See Form 1 attached for site information. Information provided in this permit renewal application includes effluent discharge monitoring data collected for Outfall 001 from June 2020 to August 2022 (See Form 2C—Section 1 Attachments for outfall location). Monitoring was performed in accordance with permit requirements for analytical monitoringof Y discharged effluent. Information provided in this permit renewal application reflects effluent discharge monitoring data provided in monthly discharge monitoring reports (DMRs) submitted to the Department from June 2020 to August 2022.This information reflects the nature of effluent discharge water based on current operations. A summary of effluent flow and characteristic information is provided below. Data from Monthly DMR's for the past 26 months from June 2020 to August 2022 are provided in the tables in the Form 2C-Section 7 Attachments of this narrative. Facility Description The manufacturing process at the facility consists of an integrated system of leaching, solvent extraction, and electrowinning processes. This facility replaced a former zinc smelter. Feedstock for the Mooresboro facility, including metal bearing oxides and other raw materials, is managed in solution throughout the process. Valuable metal products are removed as precipitates,concentrates, and high-grade zinc metal. As detailed on the water flow line drawing included in the Form 2C—Section 2 Attachments,the facility differs from a traditional definition of a process facility with wastewater effluent as there is no wastewater treatment system. Removal from the process streams of what would otherwise be considered pollutants represents the generation of commercial products for this facility. Process units described on the line drawing extract valuable metals and products, most of which are listed as effluent discharge parameters. Once all cost-effective metals extraction is achieved,the resulting process wastewater stream requires no further treatment to comply with the categorical effluent standards applicable to the discharge. These process cycles are all inherent to facility operations. The uniqueness of the facility is made clear in the fact that it is only one of three facilities in the world that performs these processes. Permit History NPDES Effluent Discharge Permit No. NC0089109 ("the permit" or"the current permit") was issued to AZP for the discharge of process water effluent to the Broad River on June 9, 2020, effective July 1, 2020, and expiring July 31, 2023. On September 20, 2022,the facility's name was changed to Befesa Zinc Metals, LLC. NCDE DW Q/ Q was notified of this change via a Name Change Form. g g 1 In addition to this permit,the plant has two additional NPDES Permits: ■ NCG500677 issued by NCDEQ on January 6, 2021 -Certificate of coverage for discharge of non-contact cooling water, cooling tower and boiler blowdown, condensate, exempt stormwater, cooling water associated with hydroelectric operations, and similar wastewaters under the DEQ's General Permit NCG50000. Currently this plant continues to route these discharges through the stormwater outlet. Befesa has plans to reroute this water back into the process where it can be reused. This modification is planned for calendar year 2023 and is not anticipated to impact the parameters in this permit. ■ NCS000562 Issued by NCDEQ May 2, 2018,for the discharge of stormwater to the Broad River. Fish Tissue Study The fish tissue study required by Section A.4 of the permit in the Broad River was performed in the summer of 2022. Results have been reported to NCDEQ electronically. A copy and summary of the results have been included here for reference in Appendix 2. Discharge Volume The current permitted monthly average discharge volume is 980,000 gallons/day (0.980 MGD). As the facility production has increased over the current permit period,the effluent discharge volume has also increased accordingly while staying within the 0.98 MGD limit. The reported maximum monthly average discharge volume is 0.957 MGD with the monthly average for the permit period being 0.875 MGD. While the monitoring data summarized in Form 2C Section 7 and in this narrative includes data from the start of the permit period (June 2020)to present,the average monthly discharge of 0.875 MGD is only based on flow data back to January 2021. It was determined that the lower monthly average flows from the ramp up production period are not representative of the facility flow (i.e.,flows mostly below 0.80 MGD). Effluent Limitations and Monitoring Requirements As is now required by NCDEQ, EPA Forms 1 and 2C were completed for the facility, an existing industrial facility discharging process wastewater. The facility has met its permit limits for flow, pH, and Total Cadmium. The pH limits of>_6 SU and 5_9 SU were not exceeded per the daily averages recorded,the minimum daily average being 6.44 and the maximum daily average being 8.34. The Total Cadmium monitoring is discussed in further detail later in this narrative as it pertains to the Cadmium Compliance Schedule. The facility is requesting a waiver for the following parameters, as was done for the last permit: ■ Biochemical Oxygen Demand (BOD5) ■ Chemical Oxygen Demand (COD) ■ Total Organic Carbon (TOC) ■ Temperature (winter) ■ Temperature (summer) 2 The facility still has reason to believe that BOD5, COD,TOC, and temperature are not pollutants of concern significantly present in the effluent because of the nature of the facility operations. There are no sources that would contribute levels of these parameters with a reasonable potential to exceed water quality standards in the effluent discharge. Tables A through E in Form 2C were completed with quantitative results listed for those pollutants/parameters for which testing is required per the current permit. This includes those listed in the permit requiring quarterly or more frequent monitoring as well as the Priority Pollutants listed in Section A.5 of the permit. The permit does list parameters under the Section A.5 Priority Pollutants Analysis corresponding to pollutants/parameters in Table B Sections 1 "Toxic Metals, Cyanide, and Total Phenols", Section 2 "Organic Toxic Pollutants (GC/MS Fraction—Volatile Compounds)", Section 3 "Organic Toxic Pollutants (GC/MS Fraction—Acid Compounds)", and Section 4 "Organic Toxic Pollutants (GC/MS Fraction—Base/Neutral Compounds)". While the facility does fall into the Nonferrous Metals Manufacturing category and Form 2C indicates that the facility is required to monitor for pollutants in Table B Section 5 "Organic Toxic Pollutants (GC/MS Fraction—Pesticides)", none of these parameters were required by the previous permit and have not been analyzed. They are all believed absent from the facility with no reasonable potential to be present. There are two pollutants noted in Form 2C as "believed present" where no quantitative data were reported: Sulfide (as S) and Surfactants in Table C. These are not monitored by the facility currently and were not required in the previous permit. Sulfide is believed present in the effluent as sodium sulfide is used in the process as precipitating reagent. Surfactants are believed present in the effluent due to a flocculant is used in final solid- liquid separation step of the process. Cadmium Compliance Schedule The Cadmium Compliance Schedule (CCS) set forth in section A.6 of the current permit has a deadline to achieve full compliance as December 1, 2027. The compliance limits in the current permit for Cadmium are a monthly average of 350.0 µg/L and a daily maximum of 2,143 µg/L. The compliance limits for Cadmium at the completion of the CCS are a monthly average of 90.4 µg/L and a daily maximum of 454.4 µg/L. These CCS compliance limits have been consistently met by the facility, acknowledging only two exceedances in the last permit period.

December 1, 2027 The facility was approved in June 2020 to commence production of Zinc at the Mooresboro facility with an initial ramp up in production expected to be 75% production capacity by December 2020. Following the initial ramp up, Befesa was to begin an evaluation period for permit compliance with the cadmium discharge limits through June 2022. The CCS evaluation period ended on June 1, 2022, with additional activities required to be performed through December 1, 2027, as stated within the CCS. The next step of the CCS, as required by the permit, is for the facility to prepare and submit for review and comment a Preliminary Engineering Report (PER) of process alternatives and/or pollution prevention/waste minimization alternatives to achieve future compliance standards. The PER is required to be completed by December 2022. Information provided within this permit renewal application includes effluent discharge monitoring data provided in monthly discharge monitoring reports (DMRs) submitted to the Department for Outfall 001 since June 2020 (See Form 2C—Section 7 Attachments). Monitoring was performed in accordance with permit requirements for analytical and monitoring of discharged effluent. This information reflects the nature of effluent discharge water based on current operations and flows relating to the Total Cadmium present in the discharge.

Flow data indicates that the facility now averages less than the permitted flow requirements, at cadmium concentrations lower than required and is near maximum production capacity, with limited production increases planned in the future. As expressed in the NPDES permit issued on June 9, 2020, Permit No. NC0089109,the facility is required to meet interim Total Cadmium limits with final limits expressed in the permit as ramp up of the facility occurs over the permit term, see Table 2 above. As part of the permit,the facility is required to meet a CCS in order to achieve compliance with final limits. The facility monitoring results, since June 2020, indicate monthly averages and daily maximum levels of total cadmium in the discharge are consistently below the final effluent limits.

The facility is currently achieving compliance with the final effluent limits at current production rates and is requesting removal of the future CCS requirements and removal of the CCS from the renewed permit. The daily maximum and monthly average of cadmium in the facility's discharge indicate a daily maximum of 130 µg/L, well below final effluent limits daily maximum of 454.4 µg/L. The facility under current operating conditions has an allowable discharge rate of 3.716 lbs/day of Cadmium utilizing its maximum average monthly flow and future effluent limits. Considering the facility's current average monthly discharge rate of 0.875 MGD and the lower average monthly cadmium discharge concentrations of 90.4 µg/L, operations indicate that it may be feasible to request either a flow increase to allow for further production or a release from additional compliance schedule requirements since these parameters have routinely been achieved since the effective date of the current permit in 2020. The facility process is a refining process where treatment units are inherent to its process and intended for recovery of product rather than wastewater treatment intended to meet effluent guidelines. As part of the CCS,the Preliminary Engineering Report is required to provide process alternatives or waste minimization to achieve compliance while the facility increases flow to full production capacity. The facility effluent monitoring indicates that additional process or minimization is not necessary to meet permit requirements. Befesa is therefore requesting that no further action be required related to the CCS and that it be removed from the permit upon renewal.

In response, AZP developed a fish sampling plan for their facility located in Mooresboro, Rutherford County, North Carolina (Figure 1). The sampling plan was submitted to the North Carolina Division of Water Resources (NCDWR) Water Quality Permitting Section and Water Sciences Section for review and comment. Comments were addressed in a Revised Fish Tissue Monitoring Plan (Plan) submitted to NCDWR on April 16, 2020, and approved on May 5, 2020. The approved Plan is included as Attachment A to this report. The primary component of the Plan requires collection of fish tissue for evaluation of arsenic, cadmium and zinc(i.e.,target metal) concentrations. TRC Environmental Corporation (TRC) was contracted by AZP to advise, coordinate, and oversee implementation of the Plan in accordance with the permit requirements. EA Engineering, Science, and Technology, Inc., PBC (EA) performed the in-stream fish tissue collection efforts. This report presents-results of the fish tissue sampling effort and the fish tissue analytical results to satisfy requirements of the NPDES permit. Fish tissue sample collection efforts were conducted in the Broad River, Rutherford County, NC,at locations upstream and downstream of AZP's permitted discharge outfall in accordance with the NPDES requirements and the approved Plan..

The Permit expires on July 31, 2023. NPDES Permit NC0089109, Part I, A. (4) stipulates fish tissue monitoring as follows: A. (4.) FISH TISSUE MONITORING [G. S. 143-215. 1(b)] The facility shall conduct fish tissue monitoring once during the permit cycle and submit the results with the NPDES permit renewal application. The objective of this monitoring is to evaluate potential uptake of pollutants by fish tissue near the facility's discharge. The parameters analyzed in fish tissue shall be arsenic, cadmium, and zinc. The monitoring shall be conducted in accordance with the sampling plan approved by the Division. The plan should be submitted to the Division within 180 days from the effective date of the permit modification.

The q permit requires collection of fish tissue samples from two locations (upstream and downstream of the AZP discharge point in the Broad River) for analysis of arsenic, cadmium and zinc. The upstream fish tissue sampling station is within North Carolina Stream Index Reach 9-(25.5)which is classified bythe State to as WS IV. Class WS-IV waters are those used as sources of water supply ppy for drinking, culinary or food processing purposes where a WS-I, II, or III classification is not feasible. The downstream fish tissue sampling station is within North Carolina Stream Index Reach 9-(36.5), which is classified by the State as "C". Class C waters are those protected for uses such as aquatic life propagation, survival and maintenance of biological integrity (including fishing and fish), wildlife, secondary contact recreation, and agriculture. The Broad River is a rocky,flashy, and swift waterbody capable of rapid changes in water flow and depth. As such, site-specific sampling considerations were discussed in detail with the sampling team. Prior to implementation of the tissue sampling program, EA developed a detailed Standard Operating Procedures (SOP; April 2022) which integrated the NCDEQ approved Plan with site-specific considerations and additional details of the sampling and analysis program implementation. TRC and AZP reviewed the SOP for completeness and consistency with permit requirements prior to study implementation. The SOP provided additional details on sample locations, sampling schedule, collection methods, target species, sample processing and handling procedures and custody details. Attachment B includes EA's Standard Operating Procedures(SOP)Standard Operating Procedures for NPDES Permit (#NC0089109)Required Fish Tissue Collection(April 2022). EA obtained a Scientific Fish Collection License (Permit Number 22-SFC00267)from the North Carolina Wildlife Resources Commission (NCWRC)that specified the designated species, numbers of specimens, collection methods, and sampling locations. g A site reconnaissance was performed on March 22, 2022, to evaluate access points along the Broad River study area. Both upstream and downs tream access points were evaluated and identified during the reconnaissance. AZP obtained landown er permission for the he reconnaissance access to evaluate upstream and downstream access locations. A sampling schedule was developed based on multiple site considerations including river stage. United States Geological Survey(USGS) stream gaging Station 02151500,Broad River near Boiling Springs, North Carolina, was utilized to monitor river stage and discharge conditions. AZP provided turbidity readings to gauge water clarity during the sampling window. Sampling was conducted during May 2022 to target river levels and turbidity observations that would be optimal for sampling conditions.

Fish tissue samples were collected from two locations on the Broad River, upstream and downstream of the AZP facility (Figure 2). The upstream location extended from the Jack McKinney Road Bridge to approximately one mile downstream of the bridge. The downstream location began near the Highway 221 Bridge and extended approximately one mile downstream from the Highway 221 Bridge. The project area is in a mixed forested, industrial, agricultural, and commercial property use area. lnstream cover in the sampling locations on the Broad River was a combination of logs and woody debris, rocky shoals, overhanging vegetation, and undercut banks. Two primary access points were identified and utilized with access permissions in place. The primary collection method utilized was in stream boat electrofishing. Gill nets were also deployed during the sampling effort. Attachment C includes a photo log from the sampling event (presented in Appendix D of Attachment C). The Plan identified three target species representing the following three separate troph ic levels: largemouth bass (Micropterus salmoides),top predator, redbreast sunfish (Lepomis auritus), mid-trophic insectivore, and notchlip redhorse (Moxostoma hic omnivore. The minimum target collapsum), mi p p number of individual fish was six of each species and the maximum was 10 individuals of each species, from each sampling location. The Plan provided for substituting secondary species if target species were not encountered in appropriate numbers. Potential secondary target species identified in the Plan were bluegill, brassy jumprock, flat bullhead, smallmouth bass, white sucker, catfish, or carp. Edible-sized individuals, based on the North Carolina Inland Fishing, Hunting &Trapping Regulations Digest 2021-2022, or the 2019 NCDWR fish tissue monitoring data were targeted. Ten individual fish from each of the three targeted species were collected at both the upstream and downstream locations. Each individual fish met the minimum length requirements. Two duplicate samples were collected from both the upstream and downstream sample locations. Duplicate samples were collected from different target species. Attachment C provides a detailed accounting and information regarding fish processing, sample shipping, and quality control procedures. Attachment C also includes the chain of custody forms, laboratory analytical reports and field datasheets. TRC and EA performed quality control checks on the field and analytical data deliverables and a detailed review of the data reports and data summary tables. Fish tissue samples were shipped to Pace Analytical Services, Green Bay, Wisconsin,for analysis. Two fish tissue samples were duplicated for laboratory analysis at each location,for a maximum of 64 samples submitted to the laboratory for analysis. The laboratory was responsible for processing fish fillets, including scaling and filleting. All bass, suckers, and sunfish were processed as skin-on fillets. The right-side fillet was analyzed in each instance and provided sufficient tissue quantity (2 grams) required for analysis.

BR Broad River DS Downstream US Upstream LMB Largemouth bass NLR Notchlip redhorse RBS Redbrease sunfish Section 6 Conclusions Consistent with requirements outlined in the in NCDEQ approved Plan,fish tissue data were compared to fish consumption screening levels set by the North Carolina Department of Health and Human Services (NCDHHS). NCDHHS developed the following fish tissue screening levels in 2018 using USEPA published regional screening levels (RSLs) for fish tissue: ■ Arsenic: — 0.141 mg/kg; noncarcinogenic basis — 0.00031 mg/kg; carcinogenic basis ■ Cadmium: 0.471 mg/kg; noncarcinogenic basis ■ Zinc: 141 mg/kg; noncarcinogenic basis Detected concentrations of arsenic, cadmium, and zinc in fish tissue samples collected during the sampling event were less than the NCDHHS noncarcinogenic fish tissue screening values. A single detected concentration of arsenic in one upstream notchlip redhorse sample (BR-US-NLR-07) at a concentration of 0.031 (J) mg/kg is greater than the 0.00031 mg/kg NCDHHS carcinogenic target risk value for arsenic. The current NCDHHS screening levels are conservatively based on a subsistence fisherman exposure scenario. The AZP fish tissue sampling program meets the requirements of the permit and compares favorably to the NCDHHS screening levels.

In accordance with NPDES Permit NC0089109 issued to American Zinc Products(AZP) in Rutherford County, NC, enclosed is a Revised Fish Tissue Monitoring Plan(Revised Plan)developed for the collection, preparation and chemical analysis of fish samples collected from the Broad River upstream and downstream of AZP's permitted discharge outfall. The Revised Plan was edited to address comments provided to AZP by DWR in a letter dated December 20, 2019, and according to permit condition Part I,A. (4). A responsiveness summary is included to facilitate the Department's review of the Revised Plan. The Revised Plan identifies certified labs that may be used for the analytical evaluation of samples that are collected. A list of potential contractors for field work,including the collection,of fish and sample preservation is also provided. This information does not representa commitment by AZP to use any of the listed contractors or laboratories. AZP will select appropriate and qualified service providers to perform monitoring activities in accordance with the approved monitoring plan. Following agency approval of the monitoring plan,AZP will follow the revised plan to perform monitoring within the current permit cycle. Results from monitoring activities will be included with the Company's application for renewal of the NPDES Permit that is submitted to the Department. Please advise me if you have any questions. Thank you for your attention to this matter. Sincerely, Timothy R. Basilone End. Responsiveness Summary AZR Fish Tissue Revised Monitoring Plan and DWR Review Comments(12/20/2019) • Note addition of CZR Inc. Environmental Consultants Wilmington NC to contractor list. • Duplicate samples of two duplicates per site for a total of four duplicates 1. Comment: As stated in the permit,fish tissue monitoring of arsenic(As),cadmium(Cd),and zinc (Zn)must be performed once during the 5-year AZR NPDES permit cycle. For clarity please include these terms in the beginning of the AZR fish tissue monitoring plan, as well as in the final report. Response: Page one of the AZR revised Fish Sampling Plan incorporates the exact requirements of the NPDES Fish Tissue Monitoring requirement and is reproduced in the plan and labeled as Permit Item A. (4.). 2. Comment: Please omit the last two paragraphs on page 2 through page 4(including Figure 1 and Table 1).The referenced 2019. NCDWR fish tissue monitoring activities were conducted via internal agency request,and not specifically intended to serve as a model for NPDES fish tissue contaminant monitoring of the Broad River. However,it would be reasonableto list those species collected by DWR in 2019,and to specify which of those species are being targeted for the required AZR fish tissue monitoring. Response:The requested deletions have been made as requested. Target species have been identified based on the DWR suggestions and the 2019 collections. 3. Comment:The plan should outline AZR's proposal to compare arsenic(As),cadmium(Cd),and zinc(Zn) fish fillet concentrations from two separate locations in the vicinity of the AZR waste water discharge(upstream control, and downstream). Site boundaries should be separated by a reasonable distance(— I mile)to characterize the potential impact of AZR's waste water discharge on As,Cd,and Zn concentrations in fish. All of the current NPDES fish tissue monitoring plans in the state of North Carolina share this paradigm of upstream-downstream comparisons for the purpose of determining a facility's potential impact on fish contaminant levels. Response:The AZR revised Fish Sampling Plan incorporates two monitoring locations,one upstream and one downstream of the AZR facility. 4. Comment: The boundaries of the proposed downstream fish collection reach are reasonable and therefore will be accepted as is. Response:No changes necessary related to this comment. 5. Comment: We suggest placement of the upstream sample reach(control)to be above the Jack McKinney Road bridge (approximately 3 river miles above the AZR waste water discharge),to create considerable distance between the two reaches and provide similar habitat types and species assemblages for contaminant comparisons. Response: The AZR revised Fish Sampling Plan incorporates the addition of a Broad River sampling reach from the Jack McKinney Road Bridge to one mile downstream. 6. Comment:The plan should outline an attempt to collect 10 individuals of 3 targeted species from both sample reaches (total of 30 fish from each sample reach),with a minimum of 6 individuals per species meeting the permit requirement (total of 18 fish from each sample reach). Response: The revised Fish Sampling Plan now targets a goal of 3 species composed of 10 individual fish at each location with a minimum objective goal of 18 fish from each location. 7. Comment:Based on the NCDWR's 2019 fish collections, the most likely target species in this section of the Broad River include Largemouth Bass(top predator),Redbreast Sunfish (mid-trophic insectivore),and Notchlip Redhorse(mid- trophic omnivore). Other suitable species of bass,sunfish,suckers,catfish, or carp should also be retained during collection efforts.These fish samples may be submitted for analysis if target species are absent or low in numbers,or as supplemental observations. Response:The AZR revised Fish Sampling Plan has incorporated the suggested primary target species and the secondary target species as identified in the DWR comments. 8. Comment: In the final monitoring report,please provide data comparisons to fish consumption screening levels set by the North Carolina Department of Health and Human Services(NCDHHS)and the Environmental Protection Agency. Response: AZR is aware that EPA and NCDHHS fish tissue screening levels may be established based on different assumptions at different times and for different purposes. AZR will reference established standards and criteria and other such information available at the time the monitoring report is submitted. AZR will submit a final fish monitoring report with the NPDES permit renewal application as required in our NPDES permit Item A.(4.). Revised Fish Tissue Sampling Plan American.

Revised March, 2020 1JPage Fish Tissue Sampling Plan American Zinc Recycling NPDES NC0089109 Introduction This Sampling.Plan is designed to assist with the planning and responses necessary for the successful compliance of the Fish Tissue Monitoring Condition included in the American Zinc Recycling (AZR), LLC Forest City,Rutherford County NPDES Permit NC0089109. The Permit as modified is scheduled with an effective date of June 1, 2019. This Study Plan was revised. based on NCDWR Comments dated December 20,2019. The NPDES Fish Tissue Monitoring requirement is included as Permit Item A. (4.) as follows (taken directly from the permit): A. (4.) FISH TISSUE MONITORING fG.S. 143-215:.1(b)] The facility shall conduct fish tissue monitoring once during the permit cycle and submit the results with the NPDES permit renewal application. The objective of this monitoring is to evaluate potential uptake of pollutants by fish tissue near the facility's discharge. The parameters analyzed in fish tissue shall be arsenic, cadmium, and zinc. The monitoring shall be conducted in accordance with the sampling plan approved by the Division. The plan should be submitted to the Division within 180 days from the effective date of the permit modification. Upon approval, the plan becomes an enforceable part of the permit. Copies of all the study plans, study results, and any other applicable materials should be submitted.to: 1) Electronic Version Only (pdf and. CD) 2) Electronic Version (pdf and CD) and Hard Copy Division of Water Resources Division of Water Resources WQ Permitting Section - NPDES Water Sciences Section 1617 Mail Service Center 1621 Mail Service Center Raleigh, NC 27699-1 6 1 7 Raleigh, NC 27699-1621 Objectives All fish tissue sampling performed by American Zinc Recycling(AZR) will be conducted based on an approved sampling plan (this plan) according to the NPDES permit condition. Any exceptions to this approved Sampling Plan either due to unforeseen logistical challenges, difficulty in obtaining target species, safety concerns or other issues will be specifically detailed in writing and communicated to the NCDWR either during or after field sample collections are performed. The purpose of this Sampling Plan is to document sample collection and analytical procedures to be followed by AZR contractors for the collection and processing of fish samples for analysis of Arsenic, Cadmium, and Zinc as maybe found in the edible portion(fillet) of target species in the vicinity of the AZR waste water discharge. After obtaining the appropriate fish samples, fillet portions will be processed and delivered to a North Carolina certified laboratory for total arsenic, total cadmium, and total zinc. Results from this sampling and laboratory analysiswill be reported to the NCDWR with the next AZR NPDES permit renewal application as specified in the current NPDES permit under:A. (4.)FISH TISSUE MONITORING. It is the goal of this Sampling Plan to obtain ten individual fish for each of three different target species at two different locations. One location will be geographically upstream of the AZR facility and another location will be located geographically downstream of the facility. All fish submitted for chemical analysis will be representative of edible sizes. This goal, if attainable, 2 ' Page Fish Tissue Sampling Plan American Zinc Recycling NPDES:NC0089109 will represent a total of 60 individual fish fillet samples for total arsenic, total cadmium, and total zinc. Sample duplicates will also be submitted for laboratory analysis on four samples. Sampling Target Species The resident fish species of the Broad River near the American Zinc Recycling(AZR) facility are expected to include a number of different fish species based on North Carolina Division of Water Resources (NCDWR) fish sampling conducted on March 13, 2019. NCDWR Water Sciences Staff collected fish samples from the Broad River both upstream and downstream of the AZR facility's discharge. The following eight species were collected for metals analysis by NCDWR in March of 2019: Bluegill Sunfish Notchlip Redhorse (Sucker) Brassy Jumprock(Sucker) Redbreast Sunfish Flat Bullhead Smallmouth Bass Largemouth Bass White Sucker Based on the results of NCDWR fish collection sampling efforts in March 2019, this AZR Sampling Plan represents a lofty goal. At a minimum, this AZR Sampling Plan will strive for representation at each location with at least three edible species and a minimum of at least six individuals from each species selected from the target species list. Thus, a minimum total of 18 fish samples will be selected for laboratory analysis from each location. Because ten individual representatives of each species may not be attainable at each location, the sampling effort will be well documented by the selected AZR contractor. Based on NCDWR's 2019 fish collections and recommendations, the three species chosen as primary targets for collection in this study include: Largemouth Bass, Redbreast Sunfish, and Notchlip Redhorse. Each of these three species represent different trophic levels—top predator, mid-trophic insectivore, and mid trophic omnivore, respectively. If these three primary target species are absent from each location or a minimum of six individuals from each species are not attainable then secondary target species may be substituted. Secondary target species may include: Bluegill Sunfish,Brassy Jumprock, Flat Bullhead, Smallmouth Bass, White Sucker, catfish, carp or other species. Wage Fish Tissue Sampling Plan American Zinc Recycling NPDES NC0089109 Broad River Sampling Reach Locations The Broad River in the vicinity of the AZR facility can be a challenge for many fish collection approaches including gill nets,hook and line, electrofishing, and other practices. Fish samples will be obtained from two locations on the Broad River. The Broad River is a rocky, flashy, and swift waterbody capable of rapid changes in water depth. The first sampling reach location on the Broad River will start at the Jack McKinney Road Bridge(approximately three river miles above the AZR facility). The downstream extent of this sampling reach will be located no further than one mile downstream of the Jack McKinney Road Bridge. The second fish sampling reach will obtain fish from the Broad River below the AZP discharge. The second river sampling reach will start below the AZP discharge in the vicinity of the Highway 221 bridge over the Broad River(GPS location approximately Latitude 35.20585 Longitude -81.83773). The downstream extent of the sampling reach will be located approximately one mile downstream of the Highway 221 bridge over the Broad River(GPS location approximately Latitude 35.205356 Longitude -81.821633). In any case,depending on the availability of fish, the extent of each actual sampling reach will be measured and reported using reliable GPS positioning equipment. The agent or contractor selected for fish sample collections will provide copies of any figures, maps, and photographs needed to document the location of the sampling reach. Photographs documenting sampling collection activities will also be provided. Sampling Technique Methods It is anticipated that the AZR fish collection contractor will employ boat mounted powered electrofishing as the primacy means of fish collection. Depending on the selection of a suitable fish collection contractor, collections may also be accomplished using back pack electrofishing techniques,hook and line, trot lines,traps, or gilinets. In any case, the collection contractor will implement measures necessary to ensure that samples are collected and handled properly with minimal contamination and that each sampling reach is GPS verified. Field sampling efforts will continue at each location until either the primary or secondary target fish samples have been collected with a sufficient number of individuals. A minimum of three different species with six individuals will be collected from each location. Thus, fish collections are expected to result in a minimum of 36 laboratory samples for individual fish analysis (plus 4 duplicates) for arsenic, cadmium, and zinc. Regardless of collection method, the successful contractor will have knowledge,skills, and experience with all sampling techniques used to obtain fish samples. All personnel involved with electrofishing or other methods employed will be familiar with operational and safety procedures. At least two fish tissue samples will be duplicated for laboratory analysis at each location regardless of the total number of individual fish collected at each location. If field sampling approaches for fish collections are not successful in obtaining sufficient individuals(18 per site) for laboratory analysis NCDWR will be consulted to determine appropriate modifications. 4 1 P sg e Fish Tissue Sampling Plan American Zinc Recycling NPDES NC0089109 Field Data Sheet#1 and Field Data Sheet#2 will document Fish Tissue Collection Results on the day(s)of Field sampling.

All fish tissue samples will be analyzed for total arsenic, cadmium, and zinc. Laboratory analytical capabilities will be evaluated and compared to the DWR PQL reporting limits for arsenic, cadmium, and zinc prior to contractor selection. At least two fish tissue samples will be duplicated for laboratory analysis at each location regardless of the total number of individual fish collected at each location. Sample Handling and Delivery/Shipment Fish tissue samples collected for analyses must be processed and delivered/shipped to the selected certified laboratory in order to prevent decomposition or contamination. In all activities the selected contractor will avoid potential sources of arsenic, cadmium, and zinc contamination —i.e. no use of galvanized buckets,no cigarette smoking, powderless nitrile gloves will be worn in all fish handling activities. Fish will be removed from plastic live wells, holding tanks, or buckets, and rinsed with ambient water to remove foreign matter, and placed on a clean or new protective surface (i.e. aluminum foil) for sorting,weighing, length measurements, and wrapping. All samples will be processed individually. No fish will be composited into composite samples. • An individual whole fish wet weight will be determined for each fish to the nearest gram and recorded on Field Data. Sheet#2. All individual samples will be weighed on scales/balances that are properly calibrated and of adequate accuracy and precision to weigh samples to the nearest gram. Scales and or balances will be checked for calibration at the beginning of each weighing session. • A total length will be determined for each fish to the nearest centimeter using a length board such as the Wildco® Model 118 and recorded on Field Data Sheet#2). Individual fish will be identified to species under the supervision of an experienced staff familiar with North Carolina fish. Fish will be identified using current, identification manuals and other appropriate taxonomic literature (i.e.: Menhinick, E. F. 1991). • Skins on fish selected for analysis will be examined for breaks or lacerations from sampling gear as a possible source of contamination. Fish samples will be identified by species and sorted by species before any packaging or processing for delivery/shipment to the certified laboratory. • Fish selected for metals � analysis will be weighed and measured for length. Fish will be individually wrapped and labeled with sample number, species name, weight, and length in appropriate arsenic, cadmium, and zinc free wrap (i.e. new aluminum foil) and placed by species in polyethylene bags. After removing as much air as possible, the bags will be closed and tagged with the date, time, station name, species, and collector(s). • All fish (in bags)will be placed on wet ice and chilled to 4 degrees C for transport to either the certified laboratory or other suitable tissue processing location for preparation of fillet samples within 48 hours. • All fish will be processed as fillet samples. No fish samples for whole body metals analysis will be sent to the certified laboratory for whole body metals analysis. • All bass and sunfish species will be processed as fish fillet samples with skin-on intact. • All Suckers, Catfish, and Bullheads, and Carp will be processed as fillet samples with skin-off(no skin included). 71Page Fish Tissue Sampling Plan American Zinc Recycling NPDES NC0089109 Fish Tissue Sample Processing Procedures • Individual fish selected for filleting will be unwrapped and inspected carefully to ensure that they have not been compromised in any way(i.e., not properly preserved during shipment). Any specimen deemed unsuitable for further processing and analysis should be discarded and identified on the sample processing record. • Equipment used in processing fish samples for metals analysis will be free from arsenic, cadmium, and zinc contamination. As such, glass and plastic use will be prioritized. Only when necessary(i.e. knives) stainless steel will be used. Prior to preparing fish samples, all hard surfaces used in the processing will be washed with a detergent and rinsed with verified metal free water(treated by reverse osmosis—R.O.). Any necessary utensils and containers will be thoroughly cleaned and rinsed with tap water, soaked in 50 percent HNO3 (at least reagent grade)for 12 to 24 hours, and then rinsed with metal-free water. • All processing will be performed on surfaces covered with heavy duty aluminum foil. Aluminum foil will be rinsed with R.O. water between fish or new foil will be used. Filleting will be performed using talc free disposable gloves. Gloves will be rinsed between samples to prevent cross contamination. Fillets will be resected using high grade stainless steel knives. Knives are rinsed with R.O. water between fish species from the same station. • Fillets will be removed from the lateral area of the fish behind the head and pectoral fin and will include the belly flap. Extreme care will be taken not to cut into the gut cavity as it may contaminate the fillet tissue. • Filleting will be done on cutting boards covered with heavy duty aluminum foil that is changed after each filleting. Fillet tissues will be removed from whole fish with clean,high quality, corrosion-resistant stainless steel or with titanium blade knives and polypropylene handles. • Skin-on fillets will be processed by removing scales from the intact fish. Fish will be scaled prior to filleting using an automatic rotary scaler or hand scaler. Fish will then be rinsed with R.O. water to remove slime and foreign matter. Any scaling instruments will also be rinsed between fish to prevent contamination. The scale free fish fillet will be finely minced using the same knives to prepare individual fillet homogenates to ensure equal distribution of contaminants throughout the sample. These individual fillet tissue homogenates will be stored in heavy duty aluminum foil and appropriately labeled for delivery to the certified laboratory for chemical analysis. Where possible the final individual homogenized sample should be composed of approximately 100 g of tissue to ensure an adequate amount of material for analysis. Since samples will be composed of individual fish fillets it may not be possible to achieve 100g of sample in every case. • Fish fillet for skin-off analysis will be separated from the skin using knives. Fish will be skinned prior to filleting for all catfish and bullheads. Sucker and Carp fillets will be separated from the fish body and subsequently separated from the skin using knives. The skin free fish fillet will be finely minced using the same knives to prepare individual fillet homogenates to ensure equal distribution of contaminants throughout the sample. These individual fillet tissue homogenates will be stored in heavy duty aluminum foil and appropriately labeled for delivery to the certified laboratory for chemical analysis.

CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QUARTERLY) [15A NCAC 02B .0200 et seq.] The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to Ceriodaphnia dubia at an effluent concentration of 0.9%. The permit holder shall perform at a minimum, quarterlrq monitoring using test procedures outlined in the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised December 2010, or subsequent versions or "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised- December 2010) or subsequent versions. The tests will be performed during the months of January, April, July and October. These months signify the first month of each three-month toxicity testing quarter assigned to the facility. Effluent sampling for this testing must be obtained during representative effluent discharge and shall be performed at the NPDES permitted final effluent discharge below all treatment processes. If the test procedure performed as the first test of any single quarter results in a failure or ChV below the permit limit, then multiple-concentration testing shall be performed at a minimum, in each of the two following months as described in "North.Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised-December 2010) or subsequent versions. All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge Monitoring Form (MR-1) for the months in which tests were performed, using the parameter code TGP3B for the pass/fail results and THP3B for the Chronic Value. Additionally, DWR Form AT-3 (original) is to be sent to the following address: Attention: North Carolina Division of Water Resources Water Sciences Section/Aquatic Toxicology Branch 1621 Mail Service Center Raleigh, NC 27699-1621 Completed Aquatic Toxicity Test Forms shall be filed with the Water Sciences Section no later than 30 days after the end of the reporting period for which the report is made. Test data shall be complete, accurate, include all supporting chemical/physical measurements and all concentration/response data, and be certified by laboratory supervisor and ORC or approved designate signature. Total residual chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for disinfection of the waste stream. Should there be no discharge of flow from the facility during a month in which toxicity monitoring is required, the permittee will complete the information located at the top of the aquatic toxicity (AT) test form indicating the facility name, permit number, pipe number, county, and the month/year of the report with the notation of"No Flow" in the comment area of the form. The report shall be submitted to the Water Sciences Section at the address cited above. Should the permittee fail to monitor during a month in which toxicity monitoring is required, monitoring will be required during the following month. Assessment of toxicity compliance is Page 4 of 9 Permit NCO 089109 based on the toxicity testing quarter, which is the three month time interval that begins on the first day of the month in which toxicity testing is required by this permit and continues until the final day of the third month. Should any test data from this monitoring requirement or tests performed by the North Carolina Division of Water Resources indicate potential impacts to the receiving stream, this permit may be re-opened and modified to include alternate monitoring requirements or limits. NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control organism survival, minimum control organism reproduction, and appropriate environmental controls, shall constitute an invalid test and will require immediate follow-up testing to be completed no later than the last day of the month following the month of the initial monitoring. A. (3.)ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS [G.S. 143-215.1(b)] Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and program reports.

INTRODUCTION The American Zinc Products (AZP),LLC was required to develop a sampling plan to maintain compliance with the requirements issued in National Pollutant Discharge Elimination System (NPDES)permit#NC0089109. The plan was submitted to the North Carolina Division of Water Resources (NCDWR) Water Quality Permitting Section and Water Sciences Section for review and comment. Comments were addressed in December 2019 and a final version of the sampling plan was submitted in April 2020. The primary component of the sampling plan required a fish collection for evaluation of target metal concentrations present within the fish tissue. EA Engineering, Science, and Technology, Inc.,PBC (EA) will be performing fish tissue collection and facilitation services to meet the tissue collection and analysis requirements. 1.1 NPDES PERMIT REQUIREMENTS In accordance with NPDES permit#NC0089109, the following Fish Tissue Monitoring Condition requirement was stipulated therein: A. (4)FISH TISSUE MONITORING [G. S. 143-215. 1(b)j The facility shall conduct fish tissue monitoring once during the permit cycle and submit the results with the NPDES permit renewal application. The objective of this monitoring is to evaluate potential uptake of pollutants by fish tissue near the facility's discharge. The parameters analyzed in fish tissue shall be arsenic, cadmium, and zinc. The monitoring shall be conducted in accordance with the sampling plan approved by the Division. The plan should be submitted to the Division within 180 days from the effective date of the permit modification. AZP provided an updated revised fish tissue monitoring plan to the NCDWR NPDES Water Quality Permitting Section in April 2020 (AZP 2020). EA has reviewed the AZP Sampling Plan and integrated it into this SOP. 1.2 OBJECTIVE The primary objective is to fulfill the NPDES #NC0089109 Fish Tissue Monitoring Condition requirement, which consists of collecting fish tissue samples upstream and downstream of the AZP discharge in the Broad River to be analyzed for arsenic (As), cadmium(Cd), and zinc (Zn). Broad River,Rutherford County,North Carolina SOP-NPDES Fish Tissue Collection Version:FINAL Page 2 EA Engineering,Science,and Technology,Inc.,PBC May 2022 This intentionally left blank Broad River,Rutherford County,North Carolina SOP-NPDES Fish Tissue Collection Version:FINAL Page 3 EA Engineering,Science,and Technology,Inc.,PBC May 2022 2. METHODS AND MATERIALS The sampling locations, sampling schedule, collection methods, target species, sample processing procedures, and shipping details are described below. Sampling will be performed at two locations near the AZP facility within Broad River during Spring of 2022 with a target of mid-May. Three species of edible-size fish representing three different trophic levels will be targeted for tissue collection. The primary sampling gear will be boat electrofishing, which may be augmented by hook-and-line, gill nets, hoop nets, and trap nets. 2.1 SAMPLING LOCATIONS Fish samples will be obtained from two locations on the Broad River, one upstream(Figure 1) and the other downstream of the AZP facility(Figure 2). The upstream location will extend from the Jack McKinney Road Bridge to approximately one mile downstream of the bridge (Figure 1): jUpstream Start` \too1 111 4Upstream End Figure 1. Upstream Sampling Location Based on AZP's reconnaissance and the site visit on 22 March, the primary access area to the upstream sampling location will be via Jones Farms (0 Montgomery Rd. Ext.,Mooresboro,NC 28114) for which AZP has obtained permission for access and use. This area is depicted in the photographs below: •1' .:? tom .."$q,,,iC 1 h ! l ✓. Broad River,Rutherford County,North Carolina SOP-NPDES Fish Tissue Collection Version:FINAL Page 4 EA Engineering, Science,and Technology,Inc.,PBC May 2022 Based on AZP (2020),the downstream sampling location will start in the vicinity of the Highway 221 Bridge (Global Positioning System [GPS] waypoint Latitude 35.20585 and Longitude -81.83773), and end approximately one mile downstream of the Highway 221 Bridge (GPS waypoint Latitude 35.205356 and Longitude -81.821633) (Figure 2): t � rrr � Sampling Play Downstream Slant \j r�-�. f�-� pMg Plan Diwnslream End Figure 2.

'N� Tit 2.2 SAMPLING SCHEDULE Based on monthly mean river stage and flow data(USGS 02151500 Broad River near Boiling Springs,NC; Table 1) and river discharge data from 2021 (Figure 3), it was determined that sampling would be conducted no earlier than approximately mid-May to minimize river levels that would be unsafe and/or too turbid for sampling. The proposed sampling scheduled is provided in Table 2. Table 1.

(b)This could be delayed by inclement weather or additional days of sampling if requested by AZP. EA will track river stage and discharge conditions via the Broad River USGS gaging station prior to sampling, as well as predicted conditions via the Advanced Hydrologic Prediction Service. In addition, EA will also contact Mr. Charles Howell (AZP Environmental Manager)to gauge water clarity via turbidity readings. Turbid conditions can mask boating hazards (e.g.,rock outcrops, deadfalls, shallow riffle/run areas), and make electrofishing inefficient in terms of the ability to observe stunned fish. Broad River,Rutherford County,North Carolina SOP-NPDES Fish Tissue Collection Version:FINAL Page 6 EA Engineering, Science,and Technology,Inc.,PBC May 2022 2.3 COLLECTION METHODS EA's primary collection method will consist of DC-pulsed electrofishing equipment that will either be boat-mounted(16-ft jon boat with 9.9 hp outboard) or wadeable. However, gill nets, trap nets, hoop nets, and limb/trot lines may also be deployed overnight at each location. The sampling effort is estimated to encompass eight days, which will consist of four days of electrofishing and potentially two overnight sets of gill nets, trap nets, hoop nets, and/or limb/trot lines at each location. EA has obtained a Scientific Fish Collection License from the North Carolina Wildlife Resources Commission(NCWRC) that specifies the designated species, numbers of specimens, collection methods, and sampling locations (Appendix A). EA personnel assigned to this project have the knowledge, skills, and experience with all sampling techniques proposed to obtain the fish samples. In addition, all personnel involved with electrofishing or other methods employed are familiar with operational and safety procedures. 2.4 TARGET FISH SPECIES The three target species are Largemouth Bass, Redbreast Sunfish, and Notchlip Redhorse. They each represent different trophic levels—top predator, mid-trophic insectivore, and mid-trophic omnivore, respectively. If these three primary target species are absent from each location or a minimum of six appropriately-sized individuals from each species are not attainable, then secondary target species will be substituted: Bluegill, Brassy Jumprock, Flat Bullhead, Smallmouth Bass, White Sucker, catfish, carp, or other species. Edible-sized individuals,based on the North Carolina Inland Fishing, Hunting& Trapping Regulations Digest 2021-2022, or the 2019 NCDWR fish tissue monitoring data (NCDWR 2019), will be retained for each game fish species; however, minimum lengths for nongame species will be those reported by the NCDWR(2019) fish tissue monitoring data: Table 3.Minimum Lengths for Target Fish Species Species Minimum Length Inches Minimum Length Inches (Regulations Digest) (2019 NCDWR) Largemouth Bass 14 (allows 2 fish<14 [356 mm]) 8.5 (215 mm) Redbreast Sunfish none 5.0 (128 mm) Notchlip Redhorse none 10.8 (275 mm) Bluegill none 5.4 (138 mm) Brassy Jumprock none 12.7 (323 mm) Flat Bullhead none 6.7 (171 mm) Smallmouth Bass 14 (allows 2 fish<14 [356 mm]) 8.5 (216 mm) White Sucker none 11.7 (1 fish; 297 mm) Golden Redhorse none 14.3 (364 mm) The goal is to obtain six to 10 individual fish for each of the three different target species at the two sampling locations. Therefore, 18 to 30 individuals will be selected for laboratory analysis from each location. If field sampling is not successful in obtaining sufficient individuals (18 per location), the NCDWR will be consulted by TRC Companies, Inc. (TRC)/AZP personnel to determine appropriate modifications. Because sufficient individuals of each species may not be attainable at each location, the sampling effort will be well documented by EA. To that end, Broad River,Rutherford County,North Carolina SOP-NPDES Fish Tissue Collection Version:FINAL Page 7 EA Engineering,Science,and Technology,Inc.,PBC May 2022 Field Data Sheet# 1 and Field Data Sheet# 2 (Appendix B) from the Sampling Plan will be used to document the fish tissue collection results. One set of data sheets (2 pages)will be completed for each location for each day sampling is conducted. In addition, the extent of each actual sampling reach will be measured and reported using GPS positioning equipment. EA will provide a map and photographs to document the sampling activities within both locations. 2.5 FIELD SAMPLE PROCESSING Fish tissue samples collected for analyses will be processed and delivered/shipped to Pace Analytical Services (Pace) in a manner to prevent decomposition or contamination. During all activities, EA will avoid potential sources of arsenic, cadmium, and zinc contamination (e.g., no use of galvanized buckets,no cigarette smoking, powderless nitrile gloves will be worn during all fish handling activities). Fish will be removed from plastic live wells,holding tanks, or buckets, rinsed with ambient water to remove foreign matter, and placed on a clean or new protective surface (i.e.,plastic wrap) for sorting, weighing, length measurements, and wrapping. All samples will be processed individually as noted below: • An individual whole fish wet weight will be determined for each fish to the nearest gram and recorded on Field Data Sheet#2 (Appendix B). All individual samples will be weighed on scales/balances that are properly calibrated and of adequate accuracy and precision to weigh samples to the nearest gram. • Total length will be determined for each fish to the nearest millimeter using a calibrated measuring board and recorded on Field Data Sheet#2 (Appendix B). Individual fish will be identified to species by experienced staff using current identification manuals and other appropriate taxonomic literature (e.g., Boschung and Mayden 2004; Jenkins and Burkhead 1993; Marcy et al 2005; Menhinick 1991; Page and Burr 2011). • Fish with lesions or lacerations will not be kept for analysis. • Each fish will be placed in a clean plastic bag that will be externally labeled with the sample number, species name, weight, and length (Appendix C). The self-adhesive label will be additionally secured to the bag by clear packing tape. The labeled bag will be placed in a second clean plastic bag to protect the label. The sample information will then be documented on a chain-of-custody Form (Appendix D). 2.5.1 Label Format External labels will include a sample identification code that will be unique to each specimen: SITE—SPP-##-DDMMMYY-CONT: where, SITE =Location Code, SPP= Species Code, ## =chronological specimen number for this species, DDMMMYY=day,month, and year, and CONT =Contract Code (NPDES). Broad River,Rutherford County,North Carolina SOP-NPDES Fish Tissue Collection Version:FINAL Page 8 EA Engineering, Science,and Technology,Inc.,PBC May 2022 For example, the sample identification code for the third Bluegill for the NPDES contract at the upstream sampling location of Broad River on 15 May 2022, will be: BR-US—BGL-03- 15MAY22-NPDES.

The chain-of-custody will include the unique sample number, date, and time of collection, and the name and signature of the field collector. The analytical laboratory will counter-sign and provide copies to EA with the analytical report. 2.5.3 Sample Shipment and Delivery Whole fish samples will be double-bagged and frozen in an on-site chest freezer during the sampling effort. Upon sample effort completion, fish will be placed on wet ice and chilled to 4°C in insulated and water-tight coolers. Coolers will be lined with trash bags to contain ice melt and cushioned with absorbent pads and bubble wrap as needed. Packed coolers will be sealed with packaging tape to ensure proper closure of cooler lid and cooler plug (if present). A completed chain-of-custody(Appendix D) will be placed in a Ziploc®bag and taped to the lid of the cooler. Coolers will be shipped for next day delivery to Pace via FedEx or UPS. 2.6 DELIVERABLES EA will provide TRC the field datasheets, GPS waypoints, maps,photographs, additional field notes (those not included on the field datasheets), and the analytical report from the laboratory. EA will also develop summary tables describing number and type of species collected at each sampling location and designation of fish that were sent to the laboratory for analysis. All information will be reviewed by appropriate personnel prior to submittal.

LABORATORY PROCESSING AND ANALYSIS Fish tissue samples will be analyzed by Pace, which maintains accreditation in North Carolina. It should be noted that based on a review of applicable fields of accreditation, NCDWR does not certify for tissue analysis. All fish tissue samples will be analyzed for total arsenic, cadmium, and zinc. Laboratory analytical capabilities have been evaluated and compared to the NCDWR Practical Quantitation Limit(PQL)reporting limits for arsenic, cadmium, and zinc (Appendix E). Two fish tissue samples will be duplicated for laboratory analysis at each location regardless of the total number of individual fish collected at each location. Therefore, a maximum of 64 samples will be analyzed by the laboratory. The laboratory will be responsible for filleting. Their Laboratory Standard Operating Procedures (SOPs) for relevant analytical methods and the Laboratory Quality Manual have been included in Appendix F. All bass and sunfish species will be processed as skin-on fillets. Pursuant to our discussion on 13 December 2021, all suckers and carp will also be processed as skin-on fillets. In contrast, all catfish and bullheads will be processed as skin-off(no skin included) fillets. Also based on that discussion, only the right fillet will be analyzed for all samples with the left fillet saved for potential future analysis. However, for those instances where the right fillet does not provide sufficient mass for analysis, then both fillets will be combined and analyzed. The minimum mass per sample for Pace is 2g.

QUALITY CONTROL This SOP manual provides EA's staff with guidance regarding sampling methodologies, the equipment required, and specifications regarding acceptable calibration intervals and procedures for various field gear (e.g., scales/balances), communication, quality control and assurance measures, as well as health and safety information. It also establishes various other protocols to be followed through this project. In accordance with EA's Corporate Quality Management Plan (the master document for all disciplines at EA), we use SOPs to efficiently promote quality through consistency. This SOP is a project-specific document that integrates the methodologies and guidance with detailed specifications. It ensures that the AZP NPDES Permit objectives will be met and that the integrity of EA will be maintained. It also allows each staff member to understand his or her duties and responsibilities, as well as providing a means for minimizing disruptions associated with staff turnover. 4.1 EQUIPMENT CALIBRATION 4.1.1 Measuring Boards Measuring boards and rulers used to determine lengths of fish are calibrated once after purchase, manufacture, or repair. The measuring board is calibrated with a ruler or tape that is certified by the manufacturer to be traceable to the National Bureau of Standards (NBS). Ten randomly selected points between 20 and 600 mm are visually checked against the standard ruler. Only those measuring boards that are within the stated accuracy of the standard ruler(±1.5 mm) are used. Measuring boards that are outside the accuracy of the standard ruler are discarded. The results of the calibration are entered on a Calibration Record Form. 4.1.2 Measuring Scales Spring scales are calibrated semi-annually by weighing 3-5 weights that are within the appropriate weight range. All weights are class T or better, and are certified by the manufacturer to be traceable to the NBS. The readings are compared to the known weight and the results are recorded on a Calibration Record Form. Scales having less than 10 percent error are retained in service whereas those that exceed 10 percent error are adjusted and recalibrated, or removed from service and destroyed. 4.2 FIELD WORK Each field crew member will be expected to have read and have on hand at all times a copy of the SOP. A master field equipment checklist has been prepared so that the field crew has all the appropriate equipment needed for sampling (Appendix G). All specifications detailed previously will be carefully followed. Additional care will be taken to sample at the locations specifically needed to meet NPDES requirements; GPS coordinates are provided in AZP (2020) and Section 2.1 (see Figure 2) of the SOP. Two experienced(10 years or more) EA biologists Broad River,Rutherford County,North Carolina SOP-NPDES Fish Tissue Collection Version:FINAL Page 12 EA Engineering, Science,and Technology,Inc.,PBC May 2022 will conduct the field collections, which will ensure strict adherence to the SOP,proper identification of fish captured,and sound judgment regarding collection procedures and during potentially hazardous conditions. The sampling crew will be required to have our current NCWRC Scientific Fish Collection License on hand when in the field (Appendix A). 4.3 FIELD AND LABORATORY DATA EA will compare all (i.e., 100%) hand-entered field data against the hard copy field or laboratory data sheets. These comparisons will be kept as part of the project file, documented on a data processing log sheet, and be made available to the client at their request. In addition, the comparisons will be done by an experienced fisheries biologist; data will not be checked by a non-biologist. EA routinely provides this type of QC for all its projects. EA will review and perform quality control checks on the analytical data provided by Pace. After the data are received, EA will perform a data assessment screening on the laboratory's analytical data packages and electronic data deliverables (EDDs). Data will be reviewed for completeness by comparing them to the chain-of custody. Review of data usability will be accomplished by comparing the contents of the analytical data packages and quality assurance/quality control (QA/QC) results to the requirements contained in the Quality Assurance Project Plan or Work Plan, the respective methods, and the laboratory SOPs. EA will resolve any discrepancies with the laboratory and will inform AZP of any issues or delays. Broad River,Rutherford County,North Carolina SOP-NPDES Fish Tissue Collection Version:FINAL Page 13 EA Engineering, Science,and Technology,Inc.,PBC May 2022 5. HEALTH AND SAFETY Due to limited boating access of the study area, the use of electrofishing equipment, and maneuvering across forested and developed regions, personnel may potentially be exposed to a variety of hazards. Since crew safety is of the utmost importance,no personnel will be required or instructed to work in surroundings or under conditions that are unsafe or dangerous to his or her health and each individual employee will be responsible for complying with applicable safety requirements, wearing prescribed safety equipment, and preventing avoidable accidents. 5.1 BOATING AND ELECTROFISHING EA's Corporate Vessel and Operations Manual and Small Boat Operations SOP (Appendix H) provides the basic policies and procedures regarding safety and health during the performance of work involving boating and watercraft activities, which are to be followed during this study. Prior to sampling, the EA field crew will notify on-site AZP and TRC staff of EA's planned sampling route for the day. At a minimum, all boats will be equipped with required Coast Guard safety equipment(e.g., approved personal floatation devices, fire extinguisher, signal flares, horn, etc.) and a first aid kit. EA staff on board the boat will also have cell phones available to contact on-site AZP and TRC staff or emergency services in the event of an emergency. A GPS will be on board to provide emergency personnel with GPS location information if needed. EA's Electrofishing Field Manual (Appendix H)provides details on basic concepts and safety issues involving electrofishing systems, including safe equipment operations and appropriate personal protective equipment (PPE) during active sampling. Watercraft and Trailer Registrations are provided in Appendix I. 5.2 WEATHER HAZARDS Weather conditions will be taken into consideration during each sampling effort. Heavy rains, electrical storms, high winds, and extreme temperatures, for example, may create extremely dangerous situations for employees. Inclement weather may also impair equipment performance. Whenever unfavorable conditions arise, the Crew Leader will evaluate both the safety hazards and ability of the employees to effectively perform given tasks under such conditions. Work on the sampling vessel will be suspended during thunderstorms, tornadoes, hurricanes, or other severe weather events. Weather conditions will be monitored via broadcast from marine radio channel to identify the approach of severe weather situations. 5.3 HEAT STRESS Prolonged exposure to heat can result in heat rash (prickly heat),heat cramps, heat exhaustion, or heat stroke. Heat stroke is life threatening and requires immediate professional medical attention. An overview of these heat-induced illnesses and proper preventative actions are described below. Broad River,Rutherford County,North Carolina SOP-NPDES Fish Tissue Collection Version:FINAL Page 14 EA Engineering, Science,and Technology,Inc.,PBC May 2022 5.3.1 Heat Rash (Prickly Heat) Heat rash, which is commonly observed in tropical climates, is a painful temporary condition caused by clogged sweat pores, typically from sleeping in hot, humid quarters. Heat rash appears as tiny red bumps on the skin and can impair sweating, resulting in diminished heat tolerance. Heat rash can usually be cured by providing cool sleeping quarters;body powder may also help absorb moisture. 5.3.2 Heat Cramps Heat cramps are characterized by painful intermittent spasms of the voluntary muscles following hard physical work in a hot environment. Heat cramps usually occur after heavy sweating and often begin towards the end of the workday. The cramps are caused by a loss of electrolytes, principally salt. This results in fluids leaving the blood and collecting in muscle tissue, resulting in painful spasms. Treatment consists of increased ingestion of commercially available electrolytic"sports" drinks (because of individual sensitivity, it is best to dilute by doubling the amount of water required by package directions or add water to the liquid form). 5.3.3 Heat Exhaustion This condition is characterized by profuse sweating, weakness, low blood pressure, rapid pulse, dizziness, and frequently nausea and/or headache. The skin is cool and clammy and appears pale. The body core temperature is normal or depressed. Victim may faint and/or vomit. This is the most common work-related heat illness, and usually occurs after an extended period of work— look for signs of onset after lunch—an employee may suddenly need to sit down, feel faint, weak,or nauseated. First aid consists of placing the victim in a cool area, loosening clothing,placing in a head-low (shock prevention)position, and providing rest and plenty of fluids. Any worker who is a victim of heat exhaustion may not be exposed to a hot working environment for an absolute minimum of 24 hours, and if fainting has occurred, the victim should not return to any work until authorized by a physician. 5.3.4 Heat Stroke This is the most serious heat disorder, is life threatening, and is a true medical emergency. It results when the body's heat dissipating system is overwhelmed and shuts down (thermoregulatory failure). Heat stroke results in a continual rise in the victim's deep core body temperature, which is fatal if not checked. The symptoms are hot, dry, flushed skin, elevated body core temperature, convulsions, delirium, unconsciousness, and possibly death. First aid consists of immediately moving victim to a cool area; cool the body rapidly by immersion in cool (not cold) water or sponging the body with cool water; treat for shock and obtain immediate medical assistance. Treatment response time is critical when assisting a victim of heat stroke! Do not give coffee, tea, or alcoholic beverages. Broad River,Rutherford County,North Carolina SOP-NPDES Fish Tissue Collection Version:FINAL Page 15 EA Engineering,Science,and Technology,Inc.,PBC May 2022 5.3.5 Preventative Measures Unfortunately, there are no known PPE to prevent heat-related illnesses. However,some preventative measures to avoid heat stress include: • Frequent resting in cool or shaded areas, • Consumption of large quantities of potable water or diluted electrolyte beverages, following the suggested hydration target in Table 5: Table 5.Hydration Targets based on Air Temperature and Time Periods between Breaks Temperature Work Level Maximum Minutes Worked Hydration Target Between Hydration Breaks <80°F Normal -- 8-12 oz./hr. 80-85°F Normal -- 8-16 oz./hr. 86-90°F Normal 50 12-20 oz./hr. 91-95°F Normal 45 16-24 oz./hr. >96°F Normal 40 24-32 oz./hr. • Following a work/rest regiment from Table 6: Table 6. Work/Rest Schedule based on Air Temperature Ambient Temperature Work(hours) Rest(minutes) 70°F 3 15 75°F 2'/2 15 80°F 2 15 85°F 1'/2 15 90°F 1 15 Other factors, such as a worker's acclimatization, level of physical fitness, and age, may increase or decrease his/her susceptibility to heat stress. Before assigning a task to an individual worker, these factors will be taken into account to ensure that the task will not endanger the worker's health. If a heat-related illness is suspected or observed, the affected person must be moved to a cool or shaded area and given plenty of liquids to consume. If symptoms of a heat stroke are observed, the victim will be cooled immediately and treated as a medical emergency. Liquids will be readily available to ensure that workers stay hydrated. 5.4 BIOLOGICAL HAZARDS—INSECT BITES/STINGS Protective outer clothing such as gloves,hard hats, and coveralls can reduce the potential for insect bites and stings. Insect bite symptoms may include redness, rash, swelling, chills, fever, diarrhea, and vomiting. Any worker who has been bitten or stung and shows symptoms of a severe reaction should seek medical assistance immediately. Workers who know of their allergies to insects should advise their supervisor prior to field activities and should carry an antidote kit, if necessary. Broad River,Rutherford County,North Carolina SOP-NPDES Fish Tissue Collection Version:FINAL Page 16 EA Engineering, Science,and Technology,Inc.,PBC May 2022 When working in areas near heavy vegetation (possibly the riverbank) and to prevent contact with disease-carrying ticks, workers should wear long-sleeved shirts, long pants, and boots that extend above the ankle with socks pulled over pant cuffs or with pants legs taped to boots. Insect repellant is also an effective means of tick control. Workers should check clothing, skin, and hair for the presence of ticks periodically and thoroughly at the end of each workday. If a tick attaches to the body, it should be removed by gently tugging with tweezers where the mouth enters the skin. The tick should not be killed prior to removal. 5.5 BIOLOGICAL HAZARDS —SNAKES There are six species of venomous snakes present in North Carolina and care must be taken to avoid encounters and potential bites. Staff will be aware of physical appearances of venomous snakes but will take care to avoid all snakes. When walking through wooded areas, check the location of your next step prior to moving forward to ensure it is clear of snakes. Wear closed- toed shoes and long pants to reduce the likelihood of a snake bite if a venomous snake is disturbed. 5.6 BIOLOGICAL HAZARDS—FISH Care must be taken and the proper PPE used when handling certain fish species to avoid getting cut, spined, or bitten. Proper handling of fish will be performed by experienced EA staff to reduce the likelihood if injury. Any worker that gets injured from a fish should seek medical attention immediately. 5.7 POISON IVY AND RELATED PLANTS Poison ivy,poison oak, and poison sumac have poisonous sap (urushiol) in their roots, stems, leaves, and fruits. The urushiol may be deposited on the skin by direct contact with the plant or by contact with contaminated objects, such as clothing, shoes, tools, and animals. Preventative measures include: wear long-sleeved shirts and long pants tucked into boots; wear cloth or leather gloves; apply barrier creams (e.g., Ivy Block) to exposed skin; and be able to identify poison ivy, oak, and sumac plants. If you are exposed, according to the U.S. Food and Drug Administration (FDA), you should quickly (within 10 minutes): 1) cleanse exposed areas with rubbing alcohol; 2) wash the exposed areas with water only (no soap yet, since soap can move the urushiol, which is the oil from the poison ivy that triggers the rash, around your body and actually make the reaction worse); 3) take a shower with soap and warm water; and 4)put gloves on and wipe everything you had with you, including shoes, tools, and your clothes, with rubbing alcohol and water. Unfortunately, if you wait more than 10 minutes, the urushiol will likely stay on your skin and trigger the poison ivy rash. You may not be able to stop it on your skin, but you might still scrub your nails and wipe off your shoes, etc., so that you do not spread the urushiol to new areas. Broad River,Rutherford County,North Carolina SOP-NPDES Fish Tissue Collection Version:FINAL Page 17 EA Engineering, Science,and Technology,Inc.,PBC May 2022 5.8 ALLERGIC REACTIONS When in the field, personnel may be exposed to allergens that can cause mild to severe allergic reactions. The following guidelines will explain how to help a person having an allergic reaction. For a mild to moderate reaction: • Calm and reassure the person having the reaction, as anxiety can worsen symptoms. • Try to identify the allergen and have the person avoid further contact with it. If the allergic reaction is from a bee sting, scrape the stinger off the skin with something firm (such as a fingernail or plastic credit card). Do not use tweezers; squeezing the stinger will release more venom. • If the person develops an itchy rash, apply calamine lotion and cool compresses. Avoid medicated lotions. • Watch the person for signs of increasing distress. • Get medical help. For a mild reaction, a physician may recommend over-the- counter medications (such as antihistamines). For a severe allergic reaction: • Check the person's airway, breathing, and circulation(the ABCs of Basic Life Support). A warning sign for dangerous throat swelling is a very hoarse, whispered voice or coarse sounds when the person is breathing air in. If the victim is having difficulty breathing,is very weak, or is losing consciousness, call for emergency medical assistance. • Calm and reassure the person. • If the person has emergency allergy medication on hand, help the person take or inject the medication. Avoid oral medication if the person is having difficulty breathing. • Take steps to prevent shock. Have the person lie flat, elevate the person's feet about 12- inches, and cover him or her with a coat or blanket. DO NOT place the person in this position if a head,neck,back, or leg injury is suspected or if it causes discomfort. Broad River,Rutherford County,North Carolina SOP-NPDES Fish Tissue Collection Version:FINAL Page 18 EA Engineering, Science,and Technology,Inc.,PBC May 2022 5.9 EMERGENCY RESPONSE PLAN In the event of an emergency, the information available at the time must be properly evaluated and the appropriate steps taken to implement the emergency response plan. The Crew Leader or senior onsite supervisor will assume command of the situation and call 911 from the nearest telephone or cell phone, notify authorities of your location(the docking point at which you will meet them), evacuate personnel as needed, and take other steps needed to gain control of the emergency. Appropriate first aid will be given and emergency contacts will be made. Emergency situations will be handled by offsite support personnel; however, initial response and first aid will be available from qualified onsite personnel. Once the situation is under control, the Crew Leader or designee will immediately call EA's Corporate Safety and Health Officer(Rob Marcase at 410-329-5192)and must complete an Accident/Loss Report(Appendix J). The nearest hospital to the project site is Spartanburg Regional Hospital, located at 101 East Wood Street in Spartanburg,South Carolina(864-560-6000).Driving directions from the study area are provided in Appendix J. 5.10 CORONAVIRUS DISEASE 2019 (COVID-19) All EA staff will be fully vaccinated against COVID-19 prior to arrival on-site. EA staff will adhere to current state and/or local PPE and social distancing requirements, as necessary. Appropriate PPE, including face masks and hand sanitizer, will be available to EA staff as needed.

A laboratory is defined by ENV as any facility, however named, that provides testing, sampling, or field measurement services. When the term `laboratory" is used in this manual, the term refers to all locations listed on the Tide Page of this manual and in Section 4.1.3 unless otherwise specified. The ENV quality management system is also referred to as the quality program throughout this document. In this context, the phrase "quality management system" and "quality program" are synonymous and may be referred to by the acronym QMS. The quality management system is the collection of policies and processes established by ENV management to consistently meet customer requirements and expectations, and to achieve the goals of providing PAS customers with high quality, cost-effective,analytical measurements and services. The quality management system is also intended to establish conformance1 and compliance with the current versions of the following international and national quality system standards: ■ ISO/IEC 17025: General requirements for the competence of testing and calibration laboratories • NELAC/TNI Standard Volume 1:Management and Technical Requirements for Laboratories Performing Environmental Analysis 'The statement of conformity to these Standards pertains only to testing and sampling activities carried out by the laboratory at its physical address,in temporary or mobile facilities,in-network,or by laboratory personnel at a customer's facility. In addition to the international and national standards,the quality management system is designed to achieve regulatory compliance with the various federal and state programs for which the laboratory provides compliance testing and/or holds certification or accreditation. When federal or state requirements do not apply to all ENV locations, the requirements for compliance to those specifications are provided in addendum to this manual or in other documents that supplement the manual. Customer-specific project and program requirements are not included in the manual in order to maintain client confidentiality. • A list of accreditation and certifications held by each laboratory associated with this manual is provided in Appendix A. • A list of analytical testing capabilities offered by each laboratory associated with this manual is provided in Appendix B. 1.2 Scope and Application This manual applies to each of the PAS locations listed on the Tide Page. The manual was prepared from the quality manual template (template) created by ENV corporate quality personnel. The template outlines the minimum requirements ENV management considers necessary for every ENV location,regardless of scope of services or number of personnel,to establish in order to maintain a quality management system that achieves the objectives of the Quality Policy (See 4.2.2). In this regard, the template is the mechanism used by the corporate officers (a.k.a. 'top Page 7 of 100 °ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. management') to communicate their expectations and commitment for the quality program to ENV personnel. Each location also has the responsibility to comply with federal and state regulatory and program requirements for which it provides analytical services and holds certification or accreditation. When those requirements are more stringent than the template, the requirements for compliance are provided in addendum to this manual or in other documents that supplement the manual. This document structure maintains consistency in the presentation of the quality management system across the network while providing the location a mechanism to describe and achieve compliance requirements on a program basis. 1.2.1 Quality Manual Template The quality manual template is developed by the Corporate Quality Director with contribution and input from corporate quality personnel and the corporate officers. Approval of the template by the corporate officers (aka "top management") confirms their commitment to develop and maintain a quality management system appropriate for the analytical services offered by the organization and to communicate their expectations of the quality program to all personnel. The template and instructions for use of the template are released by corporate quality personnel to the quality assurance manager responsible for each location (Local QM). The local QM uses the template to prepare the laboratory's manual by following the instructions provided. Since the template provides the minimum requirements by which ENV locations must abide,the laboratory may not alter the font, structure or content of the template except where specified by instruction to do so. As previously stated,program specific requirements are provided in addendum or in documents that supplement this manual. The template is reviewed by corporate quality personnel annually and updated if needed. More frequent review and revision may be necessary to manage change, to maintain conformance and compliance to relevant standards,or to meet customer expectations. See standard operating procedure (SOP) ENV-SOP-CORQ-00015 Document Management and Control(most recent revision or replacement) for more information. 1.2.2 Laboratory Quality Manual The manual is approved and released to personnel under the authority of local management whose signatures are identified on the Manual Signatory Page of this manual. The manual is reviewed annually, and location specific information is updated, if needed. More frequent review and revision may be necessary when there are significant changes to the organizational structure, capabilities,and resources of the laboratory. Review and revision of the manual is managed by the local QM. If review indicates changes to the main body of the manual are necessary to maintain conformance and compliance to relevant standards,or to meet customer expectations, the local QM will notify corporate quality personnel to initiate review and/or revision of the template. See SOP ENV-SOP-CORQ-00015 Document Management and Control(most recent revision or replacement) for more information. Page 8 of 100 ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. 1.2.3 References to Supporting Documents The template and the manual include references to other laboratory documents that support the quality management system such as policies and standard operating procedures (SOPs). These references include the document's document control number and may include the document title. This information is subject to change. For example, an SOP may be converted to a policy or the document's title may change. For these types of administrative changes,the manual and template are updated to reflect the editorial change during the manual's next scheduled review/revision cycle or the next time a new version of the manual is released,whichever is sooner. The local QM maintains a current list of controlled documents used at each location that support the quality management system. This list, known as the "Master List", lists each document used by document control number, title, version, effective date, and reference to any document(s) that the current version supersedes.When there is a difference between the manual and the Master List, the document information in the Master List takes precedence. The current Master List is readily available to personnel for their use and cross-reference. Parties external to the laboratory should contact the laboratory for the most current version. 2.0 REFERENCES References used to prepare this manual include: • • "Guidelines Establishing Test Procedures for the Analysis of Pollutants Under the Clean Water Act."

Objective work product is analytical services, data, test results, and information that is not influenced by personal feeling or opinions. The quality of being objective is also known as `impartiality'. Page 18 of 100 ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. 4.2.1.1 Impartiality The laboratory achieves and maintains impartiality by implementing and adhering to the policies and processes of the quality management system, which are based on industry accepted standards and methodologies. The laboratory's procedures for handling nonconforming work (See 4.9), corrective and preventive actions (See 4.11, 4.12) and management review (See 4.15) are the primary mechanisms used to identify risk to impartiality and to prompt actions necessary to eliminate or reduce the threat when risk to impartiality is suspected or confirmed. 4.2.1.2 Risk and Opportunity Assessment Risks are variables that make achieving the goals and objectives of the quality management system uncertain. An opportunity is something that has potential positive consequences for the laboratory. Laboratory personnel manage risks and opportunities on a daily basis by carrying out the processes that make up the quality management system. Some of the ways in which the quality management system is designed to identify,minimize,or eliminate risk on a daily basis include but are not limited to: • Capability and capacity reviews of each analytical service request to assure the laboratory can meet the customer's requirements; • Maintenance of accreditation and certification for test methods in multiple states and programs to cover a broad range of jurisdiction for regulatory compliance; • SOPs and other controlled instructional documents are provided to personnel to eliminate variability in process. These documents include actions to counter risk factors inherent in the process and are reviewed on a regular basis for on-going suitability and relevancy; • Participation in proficiency testing programs and auditing activities to verify on- going competency and comparability in performance; • Provision of on-the-job training and established protocol for quality control(QC) corrective action for nonconforming events; • An established program for ethics,and data integrity; • Tiered data review process; • Culture of continuous improvement; • Monitoring activities to assess daily and long-term performance;and • Annual critical review of the effectiveness of the quality management system. Page 19 of 100 ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT®2021-2023 Pace Analytical Services,LLC. ENV also promotes a continuous improvement culture based on the principles of lean manufacturing. These principles include 3P(Process,Productivity,Performance) and Kaizen. 3P is a platform used by Pace to share best practices and standardization across the network to achieve operational excellence. Kaizen is a team-based process used to implement tools and philosophies of lean to reduce waste and achieve flow with the purpose of improving both external and internal customer satisfaction. ENV's lean programs and activities help to mitigate risk because they generate a collective understanding of vulnerabilities and utilize group-effort to develop and implement solutions at all levels. Risk and opportunities may also be formally identified using specific risk and opportunity assessment methods such as SWOT Analysis (Strength, Weakness, Opportunity,Threats) and 3-Stage Impact/Probability Grids. 4.2.1.3 Communication of the Quality Management System This manual is the primary mechanism used by laboratory management to communicate the quality management system to laboratory personnel. To assure personnel understand and implement the quality program outlined in the manual: • All laboratory personnel are required to sign a Read and Acknowledgement Statement to confirm the employee has: 1) been informed of the manual by laboratory management, 2) has access to the manual, 3) has read the manual 4) understands the content of the manual, and 5) agrees to abide by the requirements,policies and procedures therein. • Personnel are informed that the manual provides the "what" of the quality management system. The"how to"implementation of the quality management system is provided in policy, SOPs, standard work instructions, and other controlled instructional documents. 4.2.2 Quality Policy Statement The quality policy of the laboratory is to provide customers with data of known and documented quality fit for their intended purpose. The laboratory achieves this policy by implementing the quality management system defined in this manual,by following industry accepted protocol for analytical testing and quality assurance and quality control (QA/QC) activities, by conformance with published and industry accepted testing methodologies, and by compliance with international and national standards for the competency and/or accreditation of testing laboratories.

This is accomplished by making sure the laboratory has the resources necessary to maintain capability and capacity;that staff are trained and competent to perform the tasks they are assigned; that client-facing staff are trained and prepared to find solutions to problems and to assist customers with their needs for analytical services. Customer feedback,both positive and negative,is shared with personnel and used to identify opportunities for improvement. Page 20 of 100 'I °ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. ■ The laboratory maintains a quality program that complies with applicable state, federal,and industry standards for analytical testing and competency. ISO/IEC 17025 and the TNI (The NELAC Institute) Standard is used by ENV to establish the minimum requirements of the ENV quality program. ISO/IEC 17025 is a competency standard that outlines the general requirements for the management system for calibration and testing laboratories. It is the primary quality system standard from which other quality system standards,such as the TNI Standard,are based.The TNI Standards are consensus standards that provides management and technical requirements for laboratories performing environmental analysis. • Laboratory management provides training to personnel so that all personnel are familiar with the quality management system outlined in this manual and that they understand that implementation of the quality management system is achieved by adherence to the organization's policies and procedures. • Laboratory management continuously evaluates and improves the effectiveness of the quality management system by responding to customer feedback,and other measures of performance, such as but not limited to: the results of internal/external audits, proficiency testing, metrics, trend reports, and annual and periodic management reviews. 4.2.2.1 Ethics Policy/Data Integrity Program PAS has established a comprehensive ethics and data integrity program that is communicated to all PAS employees in order that they understand what is expected of them. The program is designed to promote a mindset of ethical behavior and professional conduct that is applied to all work activities. The key elements of the PAS Ethics /Data Integrity Program include: ■ Ethics Policy(COR-POL-0004); ■ Ethics Officer; • Standardized data integrity training course taken by all new employees on hire and a yearly refresher data integrity training course for all existing employees; • Policy Acknowledgement Statements that all PAS personnel, including contract and temporary, are required to sign at the time of employment and again during annual refresher training to document the employee's commitment and obligation to abide by the company's standards for ethics, data integrity and confidentiality; • SOPs that provide instructions for how to carry out a test method or process to assure tasks are done correctly and consistently by each employee; • On the Job Training; • Data integrity monitoring activities which include,but are not limited to,primary, secondary and completeness data reviews, internal technical and system audits, data audits,data surveillance,and proficiency testing;and Page 21 of 100 aceAnal ical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. ■ Confidential reporting process for alleged ethics and data integrity issues. All laboratory managers are expected to provide a work environment where personnel feel safe and can report unethical or improper behavior in complete confidence without fear of retaliation.Retaliation against any employee that reports a concern is not tolerated. PAS has engaged Lighthouse Services,Inc. to provide personnel with an anonymous reporting process available to them 24 hours a day/7 days per week. The alert line may be used by any employee to report possible violations of the company's ethics and data integrity program. When using the reporting process, the employee does need to specify the location of concern and when reporting by email,also include the company name.Messages are collected,documented,reviewed,and will be followed up on by the Ethics Compliance Officer to resolve the matter. Investigations concerning data integrity are kept confidential.

The laboratory uses electronic document management software (eDMS) to carry out the document control procedures of the SOP. eDMS automates the process for unique document identification, version control, approval, access, and archival. The eDMS software used by ENV restricts access to archived documents except to authorized users to prevent the use of obsolete documents. The local QM maintains a master list of controlled documents used at the laboratory. The master list includes the document control number,document title,and current revision status and is made available to personnel for their reference. See SOP ENV-SOP-CORQ-0015 Document Management and Control(most recent revision or replacement) for more information. Page 24 of 100 °ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. 4.3.2 Document Approval and Issue Documents that support the quality management system are reviewed by qualified personnel and approved by laboratory management prior to release for general use. Only the approved versions of documents are available to personnel for use unless use of a draft document is authorized by management. See SOP ENV-SOP-CORQ-0015 Document Management and Control(most recent revision or replacement) for more information. 4.3.3 Document Review and Change Unless a more frequent review is required by regulatory,certification or accreditation program the laboratory formally reviews documents at least every two years to ensure the document remains current,appropriate,and relevant. Documents are also informally reviewed every time the document is used. Personnel are expected to refer to and follow instructions in controlled documents when they carry out their work activities. Consequently,any concerns or problems with the document should be caught and brought to the attention of laboratory management on an on-going basis. Documents are revised whenever necessary to ensure the document remains usable and correct. Older document versions and documents no longer needed are made obsolete and archived for historical purposes. ENV does not allow hand-edits to documents. If an interim change is needed pending re- issue of the document, the interim change is communicated to those that use the document using a formal communication channel, such as SOP Change in Progress form, email, or memorandum. The document review, revision, and archival process is managed by quality personnel at the location from which the document was released using the procedures established in SOP ENV-SOP-CORQ-0015 Document Management and Control (most recent revision or replacement). 4.4 Analytical Service Request,Tender, and Contract Review The laboratory's management and/or client service personnel perform thorough reviews of requests and contracts for analytical services to verify the laboratory has the capability,capacity,and resources necessary to successfully meet the customer's needs. These review procedures are described in laboratory SOP ENV-SOP-GBAY-0006,Sample Management and Review of Analytical Requests. The proceduresSOP(s)in this SOP s) are established to ensure that: ■ The laboratory understands the purpose of data collection in order to ensure the test methods requested are appropriate for the intended use of the data and capable of meeting the client's data quality objectives; • The laboratory and any subcontractor has the capability, capacity, and resources to meet the project requirements and expectations within the requested time frame for delivery of work product; ■ Any concerns that arise from review are discussed and resolved with the client;and Page 25 of 100 aceAnalytical i LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. • The results of review and any correspondence with the client related to this process and/or any changes made to the contract are recorded and retained for historical purposes. Capability review confirms that the in-network laboratories and any potential subcontractors hold required certification/accreditation for the test method,matrix,and analyte and verifies the laboratory can achieve the client's target compound list and data quality objectives (DQOs) for analytical sensitivity and reporting limits, QA/QC protocol, and hardcopy test report and electronic data deliverable (EDD) formats. Capacity review verifies that the in-network laboratories and any potential subcontractors are able to handle the sample load and deliver work production within the delivery timeframe requested. Resource review verifies that the laboratory and any potential subcontractors have adequate qualified personnel with the skills and competency to perform the test methods and services requested and sufficient and proper equipment and instrumentation needed to perform the services requested. 4.5 Subcontracting and In-Network Work Transfer The terms `subcontract' and "subcontracting" refers to work sent to a business external to Pace Analytical Services,LLC (PAS) and the term`subcontractor'refers to these external businesses,which are also called vendors. Work transferred within the ENV network is referred to as interregional work orders (IRWO) and network laboratories are referred to as IRWO,IR,or a network laboratory. The network of ENV laboratories offers comprehensive analytical capability and capacity to ensure PAS can meet a diverse range of client needs for any type of project. If the laboratory receives a request for analytical services and it cannot fulfill the project specifications, the laboratory's client services team will work with the client to place the work within the ENV network. When it is not possible to place the work within network, the laboratory will, with documented client approval, subcontract the work to a subcontractor that has the capabilities to meet the project specifications and can meet the same commitment agreed on between the laboratory and the client. Some client programs require client consent even for in-network work transfer, and when this applies, the client services team obtains consent as required. The laboratory retains the record of client notification and their consent in the project record for historical purposes. Whenever work is transferred to a subcontractor or an in-network laboratory, the laboratory responsible for management of the project verifies each of these qualifications: ■ The subcontractor or in network laboratory has the proper accreditation/certifications required for the project and these are current;and ■ The use of the subcontractor or in network laboratory is approved by the client and/or regulatory agency,when approval is required. Record of approval is retained in the project record. All subcontractor laboratories must maintain a quality management system like ENV and that complies with ISO/IEC 17025 and the TNI Standard(s). Page 26 of 100 ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT 02021-2023 Pace Analytical Services,LLC. ENV also evaluates and pre-qualifies subcontractors as part of the company's vendor qualification program. The complete list of approved vendors is maintained by the corporate procurement department and is made available to all ENV locations. Pre-qualification of a subcontractor does not negate the requirement for the placing laboratory to verify the capability, capacity, and resources of any selected subcontractor on a project-specific basis to confirm the subcontractor can meet the client's needs. For both subcontracting and in-network work transfer, the project specifications are always communicated to the subcontractor or the in-network laboratory by the project manager so that the laboratory performing the work is aware of and understands these requirements. The procedures for subcontracting are outlined in laboratory SOP ENV-SOP-GBAY-0005, Subcontracting Samples. � 4.6 Purchasing Services and Supplies Vendors thatprovide services and supplies to the laboratoryare pre qualified to verifythe vendor's pP p q capability to meet the needs of PAS. These needs include but are not limited to competitive pricing, capacity to fill purchase orders, quality of product, customer service, and business reputation and stability. The records of vendor evaluation and the list of approved vendors is maintained by the corporate procurement department. The procedures for vendor qualification are specified in the corporate process for vendor qualification,however named. The laboratory may purchase goods and services from any supplier on the approved vendor list. The specifications (type,class,grade,tolerance,purity,etc.) of supplies,equipment,reagents,standard reference materials and other consumables used in the testing process are specified in SOPs. The SOP specifications are based on the governing requirements of the approved reference methods and any additional program driven regulatory specification, such as drinking water compliance. All requisitions for materials and consumables are approved by the department supervisor to confirm the purchase conforms with specified requirements. After approval the requisition is handled by the laboratory's designated purchasing agent. On receipt, the product is inspected and verified before use,when applicable. The laboratory's procedure for the purchase of services and supplies is specified in laboratory SOP ENV-SOP-GBAY-0145,Laboratory Supply Procedures. 4.7 Customer Service Project details and management is handled by the laboratory's customer service team. Each customer is assigned a Project Manager (PM) that is responsible for review of contract requirements and handling laboratory to customer communication about the project status. 4.7.1 Commitment to Meet Customer Expectations The laboratory cooperates and works closely with our customers to ensure their needs are met and to establish their confidence in the laboratory's capability to meet their needs for analytical services and expectations for service. Page 27 of 100 ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. The PM is the customer's primary point of contact for each analytical service request. The PM gathers information from the customer to ensure the details of their request are understood.After samples are received,the PM monitors the progress of the project and alerts the customer of any delays or excursions that may adversely impact data usability. Laboratory supervisors are expected to keep the PM informed of project status and any delays or major issues,so that the PM can keep the client informed. The laboratory encourages customers to visit the laboratory to learn more about the laboratory's capabilities,observe performance and to meet laboratory personnel. ENV customers expect confidentiality. Laboratory personnel will not divulge or release information to a third party without proper authorization unless the information is required for litigation purposes. See Section 4.1.5.4 of this manual and policy COR-POL-0004 Ethics Policy for more information on the laboratory's policy for client confidentiality. 4.7.2 Customer Feedback The laboratory actively seeks positive and negative feedback from customers through surveys and direct communication. Information from the client about their experience working with the laboratory and their satisfaction with workproduct is used to enhance processes and practices and to improve decision making. Customer feedback is communicated to laboratory management and corporate personnel in management reports and analyzed yearly during management review (See 4.15) to identify risk and opportunity. Corrective, preventive, or continuous improvement actions are taken based on nature of and/or feedback trends. Also see sections 4.9,4.10,4.11,4.12,4.14,and 4.15 for more information about how customer feedback is managed by the laboratory and used to enhance the quality management system. 4.8 Complaints Complaints provide opportunities to improve processes and build stronger working relationships with our clients. The laboratory's complaint resolutionprocess includes three steps. First, handle and resolve the r3' P P complaint to mutual satisfaction. Second,perform corrective action to prevent recurrence (See 4.11). Third,record and track the complaint and use these records for risk and opportunity assessment and preventive action (See 4.12). Page 28 of 100 ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. 4.9 Nonconforming Work 4.9.1 Definition of Nonconforming Work Nonconforming work is work that does not conform to customer requirements, standard specifications,laboratory policies and procedures,or that does not meet acceptance criteria. The discovery of non-conforming work comes from various sources which include, but are not limited to: • results of quality control samples and instrument calibrations; • quality checks on consumables and materials; • general observations of laboratory personnel; • data review; • proficiency testing; • internal and external audits; • complaints and feedback; • management review and reports;and • regulatory and certification and accreditation actions. The way in which the laboratory handles nonconforming work depends on the significance and impact(risk) of the issue. Some issues may simply require correction,others may require investigation, corrective action(See 4.11) and/or data recall(See 4.16). When the laboratory releases data and test results associated with nonconforming QC and acceptance criteria, test results are qualified, or non-conformances are noted in the final analytical report to apprise the data user of the situation. (See 5.10) Nonconforming work also includes unauthorized departure from laboratory policies, procedures and test methods. Authorized departures are explained in the following subsections. Situations that do not conform to these conditions are considered unauthorized departure(s). 4.9.1.1 Authorized Departure from SOP An authorized departure from a test method SOP is one that has been reviewed and approved by the Department Manager,designated Acting Technical Manager for TNI for the discipline the SOP pertains to (Chemistry, Inorganic Chemistry, Microbiology), Quality Manager, or the General Manager. Management review is conducted to confirm the departure does not conflict with regulatory compliance requirements for which the data will be used or does not adversely affect data integrity. The departure may originate from client request or may be necessary to overcome a problem. An authorized departure from administrative or process-oriented SOP is typically necessary to correct an error in the SOP. These departure requests are reviewed and pre-approved by the QA Manager. Page 29 of 100 a ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT 0 2021-2023 Pace Analytical Services,LLC. Documentation of SOP departures and approval decisions are retained by the laboratory as evidence that the departure was authorized.When necessary,approved departures from test method SOPs are noted in the final test report to advise the data user of any ramification to data quality. 4.9.1.2 Authorized Departure from Test Methods (Method Modifications) When test results are associated to a published reference test method,the laboratory's test method SOP must be consistent with the test method. If the test method is mandated for use by a specific regulatory program such as drinking water or wastewater or a certification or accreditation program, such as TNI/NELAC, the SOP must also comply with or include these requirements. If the procedures in the SOP are modified from the test method,these modifications must be clearly identified in the SOP. The conditions under which the laboratory may establish an SOP that is modified from these reference documents, and what is considered a modification are specified in ENV-SOP-CORQ-0011 Method Validation and Instrument Verification (most recent revision or replacement). Modifications that do not meet the requirements of this SOP (ENV-SOP-CORQ- 0011) are unauthorized. Client requests to deviate from the test method are handled as client requests to depart from the test method SOP since it is the SOP that the laboratory follows when performing work. 4.9.1.3 Stop Work Authority Stop Work Authority provides laboratory personnel with the responsibility and obligation to stop work when there is a perceived unsafe condition or behavior that may result in an unwanted event. All laboratory and corporate personnel have the authority to stop work when needed to preserve data integrity or safety of workers. Once a stop work order has been initiated and the reason for doing so is confirmed valid;laboratory management is responsible for immediate correction and corrective action (see section 4.11) before resumption of work. Laboratory management refers to the positions listed as key personnel in section 4.1.5.1.1 of this manual. For stop work orders related to safety,the decision to resume to work after correction or corrective action may be made by the Chief Compliance Officer,the EHS Director, and the General Manager or the designees for these positions. For stop work orders related to data integrity, the decision to resume to work after correction or corrective action may be made by the Chief Compliance Officer, the Corporate Quality Director, the Corporate Program Manager, the local Quality Manager or the designees for these positions. 4.10 Continuous Improvement The laboratory's quality management system is designed to achieve continuous improvement through the implementation of the quality policy and objectives outlined in this manual. Information about Page 30 of 100 *ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. the laboratory's activities and performance is gained from many sources such as customer feedback, audits, QC, trend analysis, business analytics, management reports, proficiency testing, and management systems review. This information is subsequently used during the laboratory's corrective action (see section 4.11) and preventive action(see section 4.12) processes and during annual review of the management system (see section 4.15) to establish goals and objectives for improvement. ENV also promotes a continuous improvement culture based on the principles of lean manufacturing. These principles include 3P (Process,Productivity,Performance) and Kaizen. 3P is a platform used by Pace to share best practices and standardization across the network to achieve operational excellence. Kaizen is a team-based process used to implement tools and philosophies of lean to reduce waste and achieve flow with the purpose of improving both external and internal customer satisfaction. 4.11 Corrective Action Corrective action is a process used to eliminate the cause of a detected nonconformity. It is not the same as a correction. A correction is an action taken to fix an immediate problem. The goal of the corrective action process is to find the underlying cause(s) of the problem and to put in place fixes to prevent the problem from happening again. The corrective action process, referred to as CAPA by ENV, is one of the most effective tools used by the laboratory to prevent nonconforming work, identify risk and opportunity,and improve service to our customers. The laboratory has two general processes for corrective action: The process used for actions taken in response to day to day quality control (QC) and acceptance criteria exceptions (nonconformance) that occur during the day to day testing process are called corrections.These events do not usually include formal methods for cause analysis;instead the reason for the failure is investigated through troubleshooting or other measures. Required actions for correction of routine nonconformance is specified in laboratory SOPs. When corrective action is not taken, cannot be taken,or is not successful,test results associated with the nonconforming work are qualified in the final test report.Documentation of the nonconformance and corrective action taken is documented in the analytical record. A 7-stage corrective action process is used when there is a problem or departure from the quality management system,technical activities,or when the extent of a single problem has significant impact on data, regulatory compliance or customer needs. These problems are identified through various activities such as but not limited to: quality control trends,internal and external audits,management review, customer feedback,and general observation. The laboratory's 7 Stage CAPA Process includes: 1) Identification and Containment 2) Evaluation 3) Investigation 4) Cause Analysis 5) Action Plan 6) Implementation 7) Follow Up and Effectiveness Review The 7 stage CAPA process may be initiated by any employee. Once the process is initiated it is overseen and coordinated by laboratory management. The CAPA process is documented using a software-based workflow process called Qualtrax. The Qualtrax CAPA record includes tracking Page 31 of 100 'ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. information,dates,individuals involved,those responsible for action plan implementation and follow- up,and timelines and due dates. ENV's procedures for corrective action, are specified in corporate SOP ENV-SOP-CORQ-0018, Procedure for Corrective and Preventive Action (most recent revision or replacement). Additional explanation about certain aspects of the laboratory's corrective action process are outlined in the next three subsections. 4.11.1 Cause Analysis Cause analysis is the process of investigation used by the laboratory to identify the underlying cause(s) of the problem. Once causal factors are identified,ways to mitigate the causal factors are reviewed and corrective action(s) most likely to eliminate the problem are selected. The laboratory uses different methods to conduct this analysis.The most common approach is 5-Why,but fishbone diagrams,or even brainstorming may be appropriate depending on the situation. The method used is documented in the CAPA record. 4.11.2 Effectiveness Review Monitoring corrective actions for effectiveness is an activity shared by laboratory supervisors and quality assurance personnel. Effectiveness means the actions taken were sustainable and appropriate. Sustainable means the change is still in place. Appropriate means the action(s) taken prevented recurrence of the problem since the time corrective action was taken. The timeframe in which effectiveness review takes place depends on the event and is recorded in the CAPA record with anyaddition a on actions that need to be taken. Corrective action trends are also monitored by laboratory management and used to identify opportunities for preventive action or to gain lessons learned when actions taken were not adequate to solve the problem. See Section 4.12 (Preventive Action) and 4.15 (Management Review) for more information. 4.11.3 Additional Audits When non-conformities or other problems cast doubt on compliance with the laboratory's policies,procedures,or compliance to regulatory requirements;the quality manager schedules a special audit of the area of activity in accordance with Section 4.14.1 as soon as possible. These special audits are used to determine the scope of the problem and to provide information for the CAPA process. Additional full-scale audits are done when a serious issue or risk to the laboratory's business is identified. 4.12 Preventive Action Preventive action is an action taken to eliminate the cause of a potential nonconformity and to achieve improvement.Preventive action is a forward-thinkingprocess designed to prevent problems opposed to reacting to them (corrective action). Some examples of preventative action include,but are not limited to: ! Scheduled instrument maintenance (Preventative maintenance) ! Addition of Staff and Equipment ! Professional Development Activities Page 32 of 100 aceAnalytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. ! Implementation of New Technology The laboratory looks for opportunities for preventive action from a variety of sources including but not limited to: employee idea's,customer feedback,business partners input, trend analysis,business analytics,management reviews,proficiency testing results,lean management events, and risk-benefit analysis. Laboratory management evaluates the success of preventive actions taken in any given year during annual management review. See Section 4.15 for more information. 4.12.1 Change Management Preventive actions may sometimes result in significant changes to processes and procedures used by the laboratory.Laboratory management evaluates the risks and benefits of change and includes in its implementation of change process, actions to minimize or eliminate any risk. The types of changes for which risk are considered and managed include: infrastructure change, change in analytical service offerings, certification or accreditation status, instrumentation,LIMS changes,and changes in key personnel. 4.13 Control of Records A record is a piece of evidence about the past, especially an account of an act or occurrence kept in writing or some other permanent form. Laboratory records document laboratory activities and provide evidence of conformity to the requirements established in the quality management system. These records may be hardcopy or electronic on any form of media. 4.13.1 General Requirements 4.13.1.1 Procedure The requirements for control of records is specified in corporate policy ENV-POL- CORQ-0013 Record Management. The procedure used to implement the policy is described in laboratory SOP ENV-SOP-CORQ-0015 Document Management and Control (most recent revision or replacement) and ENV-SOP-GBAY-0119 Data and Records Archival(most recent revision or replacement). The policy is established to assure quality and technical records are identified,retained, indexed,and filed to allow for retrieval during the entire retention time frame.During storage,records are kept secure and protected from deterioration. At the end of the retention time, the records are disposed of properly in order to maintain client confidentiality and to protect the interests of the company. In general, laboratory records fall into three categories: quality, technical, and administrative. Examples of each are provided in the following table: Record Type Includes Records of: Quality Document Types listed in SOP ENV-SOP-CORQ-0015 (most recent revision or replacement) Audits:Internal and External Certificates and Scopes of Accreditation Corrective&Preventive Action Management Review -- Page 33 of 100 ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. Data Investigations Method Validation Instrument Verification Training Records Technical Raw Data Logbooks Certificates of Traceability Analytical Record Test Reports&Project Information Technical Training Records&Demonstration of Capability Administrative Personnel Records Finance/Business 4.13.1.2 Record Legibility and Storage Records are designed to be legible and to clearly identify the information recorded. Manual entries are made in indelible ink;automated entries are in a typeface and of sufficient resolution to be read. The records identify laboratory personnel that performed the activity or entered the information. Records are archived and stored in a way that they are retrievable. Access to archived records is controlled and managed. For records stored electronically, the capability to restore or retrieve the electronic record is maintained for the entire retention period. Hardcopy records are filed and stored in a suitable environment to protect from damage, deterioration, or loss. Hardcopy records may be scanned to PDF for retention. Scanned records must be checked against the hardcopyto verifythe scan is complete and legible. Administrative records are kept for a minimum of 5 years and technical and quality records are kept for 10 years unless otherwise specified by the client or regulatory program. The date from which retention time is calculated depends on the record. In general, the retention time of technical records of original observation and measurement is calculated from the date the record is created. If the technical record is kept in a chronological logbook, the date of retention may be calculated from the date the logbook is archived.The retention time of test reports and project records,which are considered technical records, is calculated from the date the test report was issued. The retention time of quality records is usually calculated from the date the record is archived. Refer to the record management policy and the laboratory SOP for more information. 4.13.1.3 Security The laboratory is a secure facility and access to records is restricted to laboratory personnel. 4.13.1.4 Electronic Records The data systems used to store electronic records is backed up in accordance with laboratory SOP ENV-SOP-GBAY-0162 Electronic Records Backup (most recent revision or replacement). Access to archived records stored electronically is maintained by personnel responsible for management of the electronic system. Page 34 of 100 ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT C 2021-2023 Pace Analytical Services,LLC. 4.13.1.5 Electronic Signature Policy Work done by ENV locations include activities that require the application of a signature. Some of this work product is in electronic format and signatures are applied electronically. The Electronic Signatures in Global and National Commerce Act (E-Sign Act) clarifies that electronic signatures are legally valid and enforceable under United States law. ENV's policy for use and application of electronic signatures is specified in corporate policy ENV-POL-CORQ-0014 Electronic Signature Policy. All employees of ENV, including temporary and contract personnel, must sign an Electronic Signature Agreement to acknowledge that they understand and accept that work activities performed by them may be authenticated with application of an electronic signature and that electronic signature has the same validity as a handwritten signature. Their signed agreement also confirms the individual has read and understands the policy and agrees to abide by the requirements for use of electronic signature stated in the policy. 4.13.2 Technical Records In addition to the requirements specified in subsections 4.13.1.1 through 4.13.1.5, the requirements in the following subsections also apply to technical records. 4.13.2.1 Description Technical records are the accumulation of data and information generated from the analytical process. These records may include forms, worksheets, workbooks, checklists, notes, raw data, calibration records, final test reports, and project record. The accumulated record essentially needs to provide adequate detail to historically reconstruct the process and identify the personnel that performed the tasks associated with a test result. 4.13.2.2 Real Time Recordkeeping Personnel are instructed and expected to always record observations, data, and calculations at the time they are made. Laboratory managers are responsible to assure that data entries,whether made electronically or on hardcopy, are identifiable to the task. 4.13.2.3 Error Correction Errors in records must never be erased, deleted or made illegible. Use of correction fluid, such as white-out is prohibited. In hardcopy records,the error is corrected by a single strike through the original entry and the new entry recorded alongside or footnoted to allow for readability. Corrections are initialed and dated by the person making the correction. If the correction is not self-explanatory, a reason for the correction is recorded. For electronic records, equivalent measures of error correction or traceability of changes made is kept. For example,audit trails provide records of change. Page 35 of 100 ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. Maintenance of proper practices for error correction is monitored through the tiered data review process described in Section 5.9.3. Laboratory records are reviewed throughout the data review process. Individuals performing these reviews flag errors that are not properly corrected and bring these to the attention of the department manager or supervisor of the work area in which the record was generated so that the problem may be addressed and corrected with the individual(s) that did not make the correction properly. 4.14 Audits The laboratory performs internal systems and technical audits to assess implementation of the QMS and compliance to this manual and to procedures,such as policy,SOP and SWI. Since the processes in this manual are based on the relevant quality system standards and regulatory and accreditation/certification program requirements the laboratory provides services for, the internal audits also assess on-going compliance to these programs. The laboratory is also audited by external parties such as regulatory agencies, customers,consultants and non-government assessment bodies (NGAB). Information from internal and external audits is used by laboratory management to address compliance concerns and opportunities where improvement will increase the reliability of data. Deficiencies,observations and recommendations from audits are managed by the local QM using the laboratory's formal CAPA process. See Section 4.11 for more information. 4.14.1 Internal Audit The laboratory's internal audit program is managed by the local QM in accordance with an audit plan established at the beginning of each calendar year. The schedule is prepared to assure that all areas of the laboratory are reviewed over the course of the year. Conformance to the schedule is reported to both laboratory management and corporate quality personnel in a monthly QA report prepared by the quality manager. Although the local QM creates the audit schedule, it is the shared responsibility of local management to assure the schedule is maintained. Laboratory supervisors cooperate with the quality personnel to provide the auditors with complete access to the work area, personnel, and records needed. Internal audits are performed by personnel approved by the quality manager. In general, personnel may not audit their own activities unless it can be demonstrated that an effective and objective audit will be carried out. The auditor must be trained, qualified, and familiar enough with the objectives,principles,and procedures of laboratory operations to be able to perform a thorough and effective evaluation. The laboratory's internal audit program ensures daily practice is consistent with laboratory's SOPs and to verify SOPs are compliant with policy and procedures. Test reports are audited to verify the final product is consistent with customer/project requirements, the work was carried out in accordance with policy and SOPs, the SOP complies with the cited reference method,test results are accurate,and of known and documented quality and properly qualified, when necessary. Special audits are performed ad hoc to follow up on a specific issue such as a client complaint, negative feedback,concerns of data integrity or ethics,or a problem identified through other Page 36 of 100 6aceAnalytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. audits. Special audits may be scheduled or unscheduled. Unscheduled internal audits are conducted whenever doubts are cast on the laboratory's compliance with regulatory requirements or its own policies and procedures. These unscheduled internal audits may be conducted at any time and may be performed without an announcement to laboratory personnel. When observations and findings from any audit(internal or external) cast doubt on the validity of the laboratory's testing results,the laboratory takes immediate action to initiate investigate the problem and take corrective action. (Also see 4.11 and 4.16) The laboratory's internal audit program and auditing procedures are further described in laboratory SOP ENV-SOP-GBAY-0108 Internal and External Audits(most current revision or replacement. 4.14.1.1 Corporate Compliance Audit ENV locations are also periodically audited by corporate quality personnel to assess the location's compliance to ENV's quality management program and to evaluate the effectiveness of implementation of the policies and procedures that make up the quality management system. The purpose of the compliance audit is to identify risks and opportunities and to assist laboratory management achieve the goals and objectives of the company's quality program. 4.15 Management Review The management team formally reviews the management system of each location under their purview on an annual basis to assess for on-going suitability and effectiveness and to establish goals,objectives, and action plans for the upcoming year. The process and procedures used to conduct this review are outlined in corporate SOP ENV-SOP- CORQ-0005 Management Review(most recent revision or replacement). At a minimum,the following topics are reviewed and discussed: • The on-going suitability of policies and procedures including EHS and waste management; • Reports from managerial and supervisory personnel including topics discussed at regular management meetings held throughout the year; • The outcome of recent internal audits; ■ Corrective and preventive actions; • Assessments by external bodies; • The results of interlaboratory comparisons or proficiency tests; • Changes in the volume and type of the work; ■ Customer and personnel feedback,including complaints; • Effectiveness of improvements /preventive actions made since last review; • Internal and external issues of relevance and risk identification; Page 37 of 100 *ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. • A review of the status of actions from prior management reviews;and • Other relevant factors,such as quality control activities,resources,and staff training. The discussion and results of this review are documented in a formal report prepared by laboratory management. This report includes a determination of the effectiveness of the management system and its processes; goals and objectives for improvements in the coming year with timelines and responsibilities,and any other need for change. Goals and action items from annual management systems review are shared with local employees and with corporate management to highlight focus areas for improvement in addition to areas in which the laboratory has excelled. 4.16 Data Integrity ENV's procedures for the investigation and response to events that may affect data integrity are described in the corporate SOPs for data inquiries and data recall and corrective and preventive action, however named. Customers whose data are affected by these events are notified in a timely manner,usually within 30 days after the impact of the problem is understood. Some accreditation programs also require notification to the accreditation body (AB) within a certain timeframe from date of discovery when the underlying cause of the issue impacts accreditation. The laboratory follows any program or project specific client notification requirements for notification,when applicable. 5.0 TECHNICAL REQUIREMENTS 5.1 General Many factors contribute to the correctness and reliability of the technical work performed by the laboratory.These factors fall under these general categories: • Human Performance • Facility and Environmental Conditions • Test Method Performance and Validation • Measurement Traceability ty • Handling of Samples The impact of each of these factors varies based on the type of work performed. To minimize negative effects from each of these factors,the laboratory accounts for the contribution from each of these categories when developing test method and process (administrative) SOPs, evaluating personnel qualifications and competence,and in the selection of equipment and supplies used. 5.2 Personnel 5.2.1 Personnel Qualifications The laboratory's program for personnel management is structured to ensure personnel are selected, qualified,and competent to perform the roles and responsibilities of their position based on education,experience,and training. Page 38 of 100 ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. Qualifications, duties, responsibilities, and authorities of each position are specified in job descriptions maintained by corporate HR(See Section 5.2.4).These job descriptions provide the general basis for the selection of personnel for hire and are used by the laboratory to communicate to personnel the duties,responsibilities,and authorities of their position. The term "personnel" refers to individuals employed by the laboratory directly as full-time, part-time, or temporary, and individuals employed by the laboratory by contract, such as through an employment agency.The term"personnel"is used interchangeably with the term "employee"throughout this manual. For purposes of this manual,these terms are equivalent. The personnel management program is structured to establish and maintain records for each of the following: • Selection of personnel; • Training of personnel; • Supervision of personnel; • Authorization of personnel;and • Monitoring Competence of personnel. 5.2.1.1 Competence Competence is the ability to apply a skill or series of skills to complete a task or series of tasks correctly within defined expectations. Competence for technical personnel authorized by ENV to provide opinion and interpretation of data to customers also includes the demonstrated ability to: • Apply knowledge, experience, and skills needed to safely and properly use equipment,instrumentation,and materials required to carry out testing and other work activities in accordance with manufacturer specifications and laboratory SOPs; • Understand and apply knowledge of general regulatory requirements necessary to achieve regulatory compliance in work product;and • Understand the significance of departures and deviations from procedure that may occur during the analytical testing process and the capability and initiative to troubleshoot and correct the problem, document the situation and decision- making process,and to properly qualify the data and analytical results. The laboratory's requirements for the competence of personnel (education, qualification, work experience, technical skills, and responsibilities) are specified in job descriptions created by management and kept by human resources (HR).The job description provides the basis for the selection of personnel for each position. An employee is considered competent when he/she has completed required training. The policies and standard operating procedures (SOPs) for the following topics are established by management as minimum required training for all personnel: ■ Ethics and Data Integrity Page 39 of 100 *ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. • Quality Manual • Safety Manual • Quality Management System • Technical Process and Procedure relevant to their job tasks • Successful Demonstration of Capability(DOC)—Analytical Personnel Only Personnel are initially authorized competent to independently carry out their assigned duties when required training is complete and documented. Records of required training and qualification provide the record of competence for the individual. Qualification records may include but are not limited to diploma, transcripts,and curriculum vitae (CV). The on-going competence of each employee is monitored by laboratory management through on-the-job performance. Analytical employees are also required to successfully complete another demonstration of capability for each test method performed on an annual basis. 5.2.2 Training (Required) ENV's training requirements are outlined in policies COR-POL-0023 Mandatory Training Policy, COR-POL-0004 Ethics Policy,and laboratory SOP ENV-SOP-GBAY-0094 Employee Orientation and Training. 5.2.2.1 Required Training The laboratory's training program includes these elements: • Scheduling of Required Training • Execution of Required Training • Documentation and Tracking of Required Training • Evaluation of Training Effectiveness Required training is delivered using various methods that incorporate techniques that appeal to the main learning styles:visual,aural,linguistic,and kinesthetic.Techniques include,on-the-job,instructor-led,self-study,eLearning,and blended. The employee's direct supervisor is responsible for oversight of completion of the employee's required training and for providing adequate time to the employee to complete training assignments. Both the supervisor and employee are responsible to make sure the employee's training status and training records for required training are current and complete. The status of completion of required training is monitored by the local QM, who provides the status to the GM at least monthly or more frequently, if necessary, to ensure required training for personnel is complete and up to date. The following subsections describe the elements of ENV's required training program. Page 40 of 100 °aceAnalytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. 5.2.2.1.1 New Hire Training New hire training requirements apply to new personnel and to existing employees starting in a new position or different work area. Required new hire training includes each of the following: • Ethics and Data Integrity(See 5.2.2.1.3) • Quality Manual/ Quality Management System (See 5.2.2.1.4) • Safety Manual and any training requirements specified in the manual. • Policies&SOPs relevant to their job tasks • Technical personnel that test samples must also successfully complete an initial demonstration of capability (IDOL) for the test methods performed before independently testing customer samples. (See 5.2.2.1.5). Independent testing means handling of client samples without direct supervision of the work activity by the supervisor or a qualified trainer. All required training must be current and complete before the employee is authorized to work independently. Until then, the employee's direct supervisor is responsible for review and acceptance of the employee's work product. 5.2.2.1.2 On-Going Training Personnel receive on-going training in each of the following topics: • Ethics and Data Integrity(See 5.2.2.1.3) • Quality Manual/ Quality Management System (See 5.2.2.1.4) • Safety Training • Changes to Policies&SOPs • Technical employees that carry out testing must also successfully complete on-going demonstration of capability(CDOC) for all test methods performed on an annual basis. (See 5.2.2.1.5) Personnel are expected to maintain their DOCs current and complete and to complete training assignments in a timely manner. 5.2.2.1.3 Ethics and Data Integrity Training Data integrity training is provided to all new personnel and refresher data integrity training is provided to all employees on an annual basis. Personnel are required to acknowledge they understand that any infractions of the laboratory data integrity procedures will result in a detailed investigation that could lead to very serious consequences including immediate termination, debarment, or civil/criminal prosecution. Page 41 of 100 ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. Completion of data integrity training is documented by employee signature to provide evidence that the employee has participated in training on this topic and understand their obligations related to data integrity. The following topics and activities are covered: • Policy for honesty and full disclosure in all analytical reporting; • Prohibited Practices; • How and when to report data integrity issues; • Record keeping. The training emphasizes the importance of proper written documentation on the part of the analyst with respect to those cases where analytical data may be useful, but are in one sense or another partially nonconforming; 1 • Training Program, including discussion regarding all data integrity procedures; • Data integrity training documentation; • In-depth procedures for data monitoring;and • Specific examples of breaches of ethical behavior such as improper data manipulations, adjustments of instrument time clocks, and inappropriate changes in concentrations of standards. All PAS personnel, including contract and temporary, are required to sign an"Attestation of Ethics and Confidentiality"at the time of employment and during annual refresher training. This document clearly identifies inappropriate and questionable behavior. Violations of this document result in serious consequences, including prosecution and termination,if necessary. Also see SOP-ENV-COR-POL-0004 Ethics Policy (most recent revision or replacement) for more information. .2.2.1.4 Management System Document Training The Quality Manual and ENV manuals, policies, and SOPs are the documents used by regulatory bodies and PAS customers to verify the laboratory's capability, competency, and compliance with their requirements and expectations. In addition to on-the-job training, employees must have a signed Read and Acknowledgement Statement (R&A) on record for the laboratory quality manual, and the policies and SOPs relating to his/her job responsibilities. This statement, whether signed by the employee electronically or by wet signature, confirms that the employee has received, read, and understands the content of the document, that the employee agrees to follow the document when Page 42 of 100 'ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. carrying out their work tasks; and the employee understands that unauthorized change to procedures in an SOP is not allowed except in accordance with the SOP departure policy(See 4. 9.1). See SOP ENV-CORQ-0016 Standard Operating Procedures and Standard Work Instructions (most recent revision or replacement) for more information. 5.22.1.5 Demonstration of Capability(DOC) Demonstration of capability is based on the employee's capability to achieve acceptable precision and accuracy for each analyte reported by the laboratory for the test method using the laboratory's test method SOP. Technical employees must complete an initial demonstration of capability (IDOC) prior to independent work on client samples analyzed by the test methods they perform.After successful IDOC, the employee must demonstrate continued proficiency(CDOC) for the test method on an annual basis. If more than a year has passed since the employee last performed the method;then capability must be re-established with an IDOC. Records of IDOC and CDOC are kept in the employee's training file. 5.2.2.2 Effectiveness of Training The results of the performance measures used to identify training needs are the same measures used by the laboratory to measure effectiveness of the training program. Improvement in key performance measures suggest the training program is successful (See 5.2.2.1). Effectiveness of individual employee training is measured by their demonstrated ability to comprehend the training material and apply knowledge and skills gained to their job task. Measurements include but are not limited to: • Testing of the employee's knowledge of the quality management system,policies, and technical and administrative procedures through various mechanisms, such as quizzes,observation,and interviews. • Demonstrated ability to convey information correctly and factuallyin written and verbal communication to internal and external parties. • Demonstrated ability to carry out tasks in accordance with SOPs and other work instructions. • Demonstrated ability to make sound decisions based on guidance and information available. • Demonstrated initiative to seek help or guidance when the employee is unsure of how to proceed. Page 43 of 100 aceAnalytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. 5.2.2.3 Supplemental Learning Supplemental learning objectives are established for newly hired personnel to aid in their development of administrative and technical skills.These learning objectives and materials, referred to as Learning Plans (LP), are created and maintained by ENV's 3P program and managed by the employee's direct supervisor. In addition to LPs, PAS maintains a wide variety of supplemental learning courses that are made available to all PAS employees for professional development. These learning materials,maintained by PAS's corporate training personnel,are accessed via the company's employee portal, PaceConnect. The learning may be self-initiated based on an employee's interest or may be assigned to the employee at the discretion of management as professional development as part of an employee's annual goals. Supplemental learning courses and learning plan activities are not prerequisites for competency (Section 5.2.1.1) and are not part of the required QMS training specified in Section 5.2.2.1. 5.2.3 Personnel Supervision Every employee is assigned a direct supervisor,however named,who is responsible for their supervision. Supervision is the set of activities carried out by the supervisor to oversee the progress and productivity of the employees that report to them. General supervisory responsibilities may include but are not limited to: ■ Hiring Employees ■ Training Employees ■ Performance Management ■ Development, oversight,and execution of personnel training plans ■ Monitoring personnel work product to assure the work is carried out in accordance with this quality manual, policies, SOPs, and other documents that support the quality management system. 5.2.4 Job Descriptions Job Descriptions that define the required education,qualifications, experience,skills,roles and responsibilities, and reporting relationships for each PAS position are established by top management and kept by corporate HR. PAS laboratories use these job descriptions as the source of positions and job titles for the laboratory. The job descriptions apply to employees who are directly employed by PAS,part-time,temporary,technical and administrative and by those that are under contract with PAS through other means. The job descriptions include the education,expertise,and experience required for the position and the responsibilities and duties,including any supervisory or managerial duties assigned to the position. 5.2.5 Authorization of Technical Personnel Laboratory management authorizes technical personnel to perform the technical aspects of their position after it has been verified that the employee meets the qualifications for the position,has successfully completed required training(Section 5.2.2.1),and the employee has Page 44 of 100 'ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. completed initial demonstrated capability (Section 5.2.2.1.5). After initial authorization, technical personnel are expected to maintain a current and complete training record, demonstrate on-going capability at least annually for each test method performed,and produce reliable results through accurate analysis of certified reference materials, proficiency testing samples,and/or routine quality control samples in order to remain authorized to continue to perform their duties. Records to support authorization including, education, experience, training, and other evaluations are kept by the laboratory. 5.3 Accommodations and Facilities 5.3.1 Facilities The laboratory is designed to support the correct performance of procedures and to not adversely affect measurement integrity or safety. Access to the laboratory is controlled by various measures,such as card access,locked doors,main entry. Visitors to the laboratory are required to sign-in and to be escorted by laboratory personnel during their visit. A visitor is any person that is not an employee of the laboratory. 5.3.2 Environmental Conditions The laboratory is equipped with energy sources,lighting,heating,and ventilation necessary to facilitate proper performance of calibrations and tests. The laboratory ensures that housekeeping, electromagnetic interference, humidity, line voltage, temperature, sound and vibration levels are appropriately controlled to ensure the integrity of specific measurement results and to prevent adverse effects on accuracy or increases in the uncertainty of each measurement. Environmental conditions are monitored,controlled,and recorded as required by the relevant specifications,methods,and procedures.Laboratory operations are stopped if it is discovered that the laboratory's environmental conditions jeopardize the analytical results. 5.3.3 Separation of Incompatible Activities The layout and infrastructure of each work area including air handling systems,power supplies, and gas supplies of each laboratory work area is specifically designed for the type of analytical activity performed. Effective separation between incompatible work activities is maintained. For example, sample storage,preparation,and chemical handling for volatile organic analysis (VOA) is kept separate from semi-volatile organic (SVOA). The laboratory separates samples known or suspected to contain high concentration of analytes from other samples to avoid the possibility for cross-contamination. If contamination is found, the source of contamination is investigated and resolved in accordance with laboratory SOPs. 5.3.4 Laboratory Security Security is maintained by controlled access to the building and by surveillance of work areas by authorized personnel. Access is controlled to each area depending on the required personnel,the sensitivity of the operations performed,and possible safety concerns.The main entrance is kept unlocked during normal business hours for visitors and is continuously Page 45 of 100 Pace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. monitored by laboratory staff. All visitors must sign a visitor's log,and a staff member must accompany them during the duration of their stay. 5.3.5 Good Housekeeping The laboratory ensures good housekeeping practices in work areas to maintain a standard of cleanliness necessary for analytical integrity and personnel health and safety. Minimally,these measures include regular cleaning of the work area. Where necessary, areas are periodically monitored to detect and resolve specific contamination and/or possible safety issues. 5.4 Test Methods 5.4.1 General Requirements The laboratory uses test methods and procedures that are appropriate for the scope of analytical services the laboratory offers. Instructions on the use and operation of equipment and sample handling, preparation, and analysis of samples are provided in SOPs. The instructions in SOPs may be supplemented with other documents including but not limited to,standard work instructions (SWI),manuals, guides,project documents and reference documents. These documents are managed using the procedures described in SOP ENV-SOP-CORQ- 0015 Document Management and Control(most recent revision or replacement) and SOP ENV- SOP-CORQ-0016 Standard Operating Procedures and Standard 'Work Instructions (most recent revision or replacement). 5.4.2 Method Selection The test methods and protocols used by the laboratory are selected to meet the needs of the customer, are appropriate for the item tested and intended use of the data, and to conform with regulatory requirements when regulatory requirements apply. In general,the test methods offered are industry accepted methods published by international, regional, or national standards. The laboratory bases its procedure on the latest approved edition of a method unless it is not appropriate or possible to do so, or unless regulatory requirements specify otherwise. The laboratory confirms that it can perform the test method and achieve desired outcome before analyzing samples (see section 5.4.5). If there is a change in the published analytical method,then the confirmation is repeated. When a customer does not specify the test method(s) to be used,the laboratory may suggest test methods that are appropriate for the intended use of the data and the type of samples to be tested. The laboratory will also inform customers when test methods requested are considered inappropriate for their purpose and/or out of date. This discourse takes place during review of analytical service requests (See Section 4.4). 5.4.3 Laboratory Developed Methods A laboratory developed method is a method developed from scratch (no published source method), a procedure that modifies the chemistry from the source method, or a procedure that exceeds the scope and application of the source method. Page 46 of 100 ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. Laboratory developed methods must be validated prior to use (see section 5.4.5) and the procedure documented in a test method SOP. The requirements for non-standard methods(Section 5.4.4)also apply to laboratory developed methods. 1 5.4.4 Non-standard Methods A non-standard method is a method that is not published or approved for use by conventional industry standards for the intended purpose of the data. Non-standard methods must be validated prior to use (see section 5.4.5) and the procedure developed and documented in a test method SOP. At a minimum,the following information must be included in the procedure: • Title/Identification of Method; • Scope and Application; • Description of the type of item to be analyzed; • Parameters or quantities and ranges to be determined; • Apparatus and equipment,including technical performance requirements; • Reference standards and reference materials required; • Environmental conditions required and any stabilization period needed;and • Description of the procedure,including: o Affixing identification marks, handling, transporting, storing and preparing of items; o Checks to be made before the work is started; o Verifying equipment function and,where required, calibrating and/or adjusting the equipment before each use; o Method of recording the observations and results; o Any safety measures to be observed; o Criteria and/or requirements for approval/rejection; o Data to be recorded and method of analysis and presentation;and o Uncertainty or procedure for estimating uncertainty. Use of a non-standard method for testing must be agreed upon with the customer. The agreement, which is retained by the laboratory in the project record, must include the specifications of the client's requirements, the purpose of testing,and their authorization for use of the non-standard method. 5.4.5 Method Validation 5.4.5.1 Validation Description Validation is the process of conformation and the provision of objective evidence that the stated requirements for a specific method/procedure are fulfilled. Page 47 of 100 'ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. The laboratory's requirements and procedures for method validation are outlined in SOP ENV-SOP-CORQ-0011 Method Validation and Instrument Verification(most recent revision or replacement). 5.4.5.2 Validation Summary All test methods offered by the laboratory are validated before use to confirm the procedure works and the data and results achieved meet the goals for the method and repeated when there are major changes to the laboratory procedure. Results of validation are retained are kept in accordance with method validation SOP and the corporate policy ENV-CORQ-POL-0013 Record Management (most recent revision or replacement). 5.4.5.3 Validation of Customer Need The validation process includes review of accuracy, precision, sensitivity, selectivity, linearity, repeatability, reproducibility, robustness, and cross-sensitivity of the procedure against general customer needs to ensure the laboratory's procedure will meet those needs. The following subsections highlight some of these concepts: 5.4.5.3.1 Accuracy Accuracy is the degree to which the result of a measurement, calculation, or specification conforms to the correct value or a standard. When the result recovers within a range from the known value (control limit); the result generated using the laboratory's test method SOP is considered accurate. 5.4.5.3.2 Precision Precision refers to the closeness of two or more measurements to each other. It is generally measured by calculating the relative percent difference (RPD) or relative standard deviation(RSD) from results of separate analysis of the same sample. Precision provides information about repeatability, reproducibility, and robustness of the laboratory's procedure. 5.4.5.3.3 Limits of Detection(LOD) (Chemistry) The LOD is the minimum result which can be reliably discriminated • from a blank with a predetermined confidence level. The LOD establishes the limit of method sensitivity and is also known as the detection limit(DL) or the method detection limit(MDL). Values below the LOD cannot be reliably measured and are not reported by the laboratory unless otherwise specified by regulatory program or test method. The LOD is established during method validation and after major changes to the analytical system or procedure that affect sensitivity are made. Page 48 of 100 'ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. 5.4.5.3.4 Limits of Quantitation (LOQ) and Reporting Limit (RL) The LOQ is the minimum level, concentration, or quantity of a target analyte that can be reported with a specified degree of confidence. The LOQ is established at the same time as the LOD. The LLOQ is the value of the lowest calibration standard included in the calibration curve. The LLOQ establishes the lower limit of quantitation. The LOQ and LLOQ represent quantitative sensitivity of the test method. ■ The LOQ must always be equal to or greater than the LLOQ and the LLOQ must always be greater than the LOD. • Any reported value (detect or non-detect) less than the LLOQ is a qualitative value. The RL is the value to which the presence of a target analyte is reported as detected or not detected. The RL is project-defined based on project data quality objectives (DQO). In the absence of project specific requirements, the RL is usually set to the LOQ or the LLOQ. The laboratory's procedures for LOD/LOQ determination is detailed in laboratory SOP ENV-SOP-GBAY-0106,Determination of the LOD and LOQ. The local SOP is based on guidance provided by corporate quality and must comply with 40CFR 136 Appendix B and the TNI Standard. 5.4.5.3.5 Linearity Linearity is a mathematical concept applied to calibration models that employ multiple points to establish a calibration range used for quantitative analysis. Linearity is measured differently based on the calibration model. In general, if linearity is demonstrated then the slope of the response of standards are sufficiently close to one another. The accuracy of the linear regression and non-linear curves is verified by checking percent error or relative standard error(RSE), which is the process of refitting calibration data back to the model to determine if the results are accurate. For linear curves that use average calibration or response factor, error is measured by relative standard difference (RSD). Linearity also establishes the range of quantitation for the test method used which directly impacts the sensitivity of the test method and uncertainty in measurement results. As previously noted, the LLOQ establishes the lower limit of quantitation. Similarly, the upper range of linearity establishes the upper limit of Page 49 of 100 t2eAnaIjicaI LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. quantitation. In general,results outside of this range are considered qualitative values. However, some inorganic methods allow for extension of the linear range above the upper limit of quantitation when accuracy at this value is verified. Linearity can also be used to establish repeatability, reproducibility, and robustness of the laboratory's test method. When linearity is demonstrated using a specific calibration model during method validation, then use of this same calibration model to achieve linearity on a day to day basis confirms the laboratory's method is repeatable,reproducible,and robust. 5.4.5.3.6 Demonstration of Capability(DOC) The DOC performed during method validation confirms that the procedure demonstrated acceptable precision and accuracy. The procedure used for DOC for method validation is the same as described in section 5.2.2.1.5 for demonstration of analyst capability. 5.4.6 Measurement Uncertainty The laboratory provides an estimate of uncertainty in testing measurements when required or on client request. In general, the uncertainty of the test method is reflected in the control limits used to evaluate QC performance. (See 5.9.1.1.9). ISO/IEC supports this concept with language that reads when a well-recognized test method specifies limits to the values of the major source of uncertainty of measurement and specifies the form of presentation of calculated results, the laboratory has satisfied the requirements on analytical uncertainty by following the test method and reporting instructions. When measurement uncertainty cannot be satisfied through control limits,the laboratory will provide a reasonable estimation of uncertainty. A reasonable estimation is based on knowledge of method performance and previous experience. When estimating the analytical uncertainty, all uncertainty components which are of importance in the given situation are taken into account. 5.4.7 Control of Data The laboratory has policies and processes in place to assure that reported data is free from calculation and transcription errors,that quality control is reviewed and evaluated before data is reported,and to address manual calculation and integration. 5.4.7.1 Calculations,Data Transfer, Reduction and Review Whenever possible, calculations, transfer of data, and data reduction are performed using validated software programs (See 5.4.7.2). If manual calculations are performed, the results of these calculations are verified during the data review process outlined in section 5.9.3. 5.4.7.11 Manual Integration The laboratory's policy and procedures for manual integration are provided in corporate SOP ENV-SOP-CORQ-0006 Manual Integration (most recent revision or replacement). Page 50 of 100 ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT 02021-2023 Pace Analytical Services,LLC.

Required documentation of manual integration includes: ■ complete audit trail to permit reconstruction of before and after results; ■ identification of the analyst that performed the integration and the reason the integration was performed;and • identification of the individual(s) that reviewed the integration and verified the integration was done and documented in compliance with the SOP. 5.4.7.2 Use of Computers and Automated Acquisition Whenever possible the laboratory uses software and automation for the acquisition, processing,recording,reporting,storage, and/or retrieval of data. Software applications developed by PAS are validated by corporate IT for adequacy before release for general use. Commercial off the shelf software is considered sufficiently validated when the laboratory follows the manufacturer or vendor's manual for set-up and use. Records of validation are kept by the corporate information technology (IT) group or by the local laboratory, whichever group performed the validation. The laboratory's process for the protection of data stored in electronic systems include: • Individual user names and passwords for Laboratory Information Management Systems (LIMS) and auxiliary systems used to store or process data. • Employee Training in Computer Security Awareness • Validation of spreadsheets used for calculations to verify formulas and logic yield correct results and protection of these cells to prevent unauthorized change. • Operating system and file access safeguards • Protection from Computer Viruses • Regular system backup;and testing of retrieved data The laboratory's process for software development and testing process includes: • Verification the software application works as expected and is adequate for use and fulfills compliance requirements,such as the need to record date/time of data generation. • Change control to assure requests for changes are reviewed and approved by management before the change is made. • Communication channels to assure all staff are aware of changes made.

These procedures are detailed in laboratory SOPs ENV-SOP-CORQ-0015 Document Management and Control. 5.5 Equipment 5.5.1 Availability of Equipment The laboratory is furnished with all equipment and instrumentation necessary to correctly perform the tests offered in compliance with the specifications of the test method and to achieve the accuracy and sensitivity required. 5.5.2 Calibration Equipment and instrumentation are checked prior to use to verify it performs within tolerance for its intended application. Laboratory management is made aware of the status of equipment and instrumentation and any needs for either on a daily basis. This information is obtained during laboratory walkthroughs (LDM) that are conducted as part of the laboratory's lean program. 5.5.2.1 Support Equipment The laboratory confirms support equipment is in proper working order and meets the specifications for general laboratory use prior to placement in service with intermediate checks thereafter. Equipment that does not meet specifications is removed from service until repaired or replaced. Records of repair and maintenance activities are maintained. Procedures used to carry out and record these checks are outlined laboratory in SOP ENV-SOP-GBAY-0115 Support Equipment. 5.5.2.2 Analytical Instruments Analytical instruments are checked prior to placement in service in accordance with SOP ENV-SOP-CORQ-0011 Method Validation and Instrument Verification(most recent revision or replacement). After the initial service date,the calibration of instruments and verification calibration is performed in accordance with local test method SOPs. The calibration procedures in the test method SOPs comply with the requirements for acceptable calibration practices outlined in corporate policy ENV-POL-CORQ- 0005 Acceptable Calibration Practices(most recent revision or replacement),the reference methods,and any applicable regulatory or program requirements. 5.5.3 Equipment Use and Operation Equipment is operated and maintained by laboratory personnel that are trained on the test method SOP. Up-to-date instructions and procedures for the use and maintenance of analytical equipment are included in SOPs and/or supplemental documents such as standard work instructions (SWI) or instrument manuals which are made readily accessible in the work area to all laboratory personnel. Page 52 of 100 ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. 5.5.4 Equipment Identification The laboratory uniquely identifies equipment by serial number or any other unique ID system, when practical. The identifier is included in the equipment list maintained by the quality department. 5.5.5 Equipment Lists and Records 5.5.5.1 Equipment List The laboratory maintains a master list of equipment that includes information about the equipment including a description, manufacturer, serial number, date placed in service, condition when received,identity,and the current location in the laboratory. The date of purchase is tracked by the procurement record. The equipment list(s) for each location covered by this manual is provided in Appendix E. 5.5.5.2 Equipment Records In addition to the equipment list,the laboratory maintains records of equipment that include: • Verification that equipment conforms with specifications. • Calibration records including dates, results, acceptance criteria, and next calibration dates. • Maintenance plan and records • Records of damage,malfunction,or repair The laboratory follows an equipment maintenance program designed to optimize performance and to prevent instrument failure which is described in laboratory SOP ENV-SOP-GBAY-0098 Preventative, Routine, or Non-routine Maintenance (most recent revision or replacement) or in individual test method SOPs. The maintenance program includes routine maintenance activities which are performed as recommended by the manufacturer at the frequency recommended and non-routine maintenance, which is performed to resolve a specific problem such as degradation of peak resolution, shift in calibration relationship,loss of sensitivity, or repeat failure of instrument performance checks and quality control samples. Maintenance is performed by laboratory personnel or by outside service providers. All maintenance activities performed by laboratory personnel are recorded by the individual(s) that performed the activity at the time the maintenance was performed in an instrument maintenance log. The maintenance record minimally includes the date of maintenance, the initials of the person(s) performing maintenance, a description of the activity performed,why (when the maintenance is non-routine), and the return to analytical control. When maintenance is performed by an external vendor, the laboratory staples the service record into hardcopy maintenance logs or scans the record for easy retrieval. The laboratory provides unrestricted access to instrument maintenance logs in order to promote good instrument maintenance and recordkeeping practices. Page 53 of 100 aceAnalytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. If an instrument must be moved, the laboratory will use safe practices for handling and transport to minimize damage and contamination. 5.5.6 Out of Service Protocol Equipment that has been subjected to overloading, mishandling, gives suspect results, has been shown to be defective,or is performing outside of specified limits is taken out of service and either removed from the work area or labeled to prevent accidental use until it has been repaired and verified to perform correctly. When analytical equipment is taken out of service,the laboratory examines the potential effect it may have had on previous analytical results to identify any non-conforming work. (See section 4.9). 5.5.7 Calibration Status The laboratory labels support equipment to indicate calibration status, whenever practicable or otherwise maintains the calibration status in a visible location in the work area. These procedures are described in laboratory SOP ENV-SOP-GBAY-0115 Support Equipment(most recent revision or .re lacement P ) The calibration status of analytical instruments is documented in the analytical record.Analysts verify on-going acceptability of calibration status prior to use and with instrument performance check standards. These procedures are described in test method SOPs. 5.5.8 Returned Equipment Checks When equipment or an instrument is sent out of the laboratory for service, the laboratory ensures that the function and calibration status of the equipment is checked and shown to be satisfactory before the equipment is returned to service.These procedures are outlined in SOP ENV-SOP-CORQ-0011 Method Validation and Instrument Verification (most recent revision or replacement). 5.5.9 Intermediate Equipment Checks The laboratory performs intermediate checks on equipment to verify the on-going calibration status. For example, most test methods require some form of continuing calibration verification check and these procedures are included in the test method SOP. Periodic checks of support equipment are also performed;see laboratory SOP ENV-SOP-GBAY-0115 Support Equipment(most recent revision or replacement) for more information. 5.5.10 Safeguarding Equipment Integrity The laboratory safeguards equipment integrity using a variety of mechanisms that include but are not limited to: • Adherence to manufacturer's specification for instrument use so that settings do not exceed manufacturer's recommendation or stress the performance of the equipment. • Established maintenance programs. • Transparent maintenance records and unrestricted access to maintenance logs. • Validation and approval of software before use. • Audits to confirm instrument settings are consistent with SOPs.

Traceability requires an established calibration hierarchy of equipment (instruments) used during testing including equipment used for subsidiary measurements. The laboratory assures this equipment is calibrated prior to being put into service and that the reference standard and materials used for calibration are traceable to the international standard of units (SI) or national measurement standard. When strict traceability to SI units cannot be made,the laboratory establishes traceability with the use of reference standards and equipment obtained from competent suppliers that provide calibration certificates and/or certificates of analysis (COA). 5.6.2 Equipment Correction Factors When correction factors are used to adjust results the laboratory will assure that results in computer software are also updated. For example,if the direct instrument or reading output must be corrected based on preparation factor or concentration factors, laboratory management will assure the corrected result is also updated in the software. 5.6.3 Specific Requirements 5.6.3.1 Requirements for Calibration Laboratories The laboratory does not offer calibration services to customers. 5.6.3.2 Requirements for Testing Laboratories The laboratory has procedures in place to verify equipment is calibrated prior to being put into service (See 5.5.2) and ensures the reference standard and materials used for calibration are traceable to the international standard of units (SI) or national measurement standard. When strict traceability to SI units cannot be made, the laboratory establishes traceability with the use of reference standards and equipment obtained from competent suppliers that provide calibration certificates and/or certificates of analysis (COA). 5.6.4 Reference Standards and Reference Materials 5.6.4.1 Reference Standards The laboratory uses reference standards of measurement to verify adequacy of working weights and thermometers. The working weight is the weight(s) used for daily balance calibration checks and the working thermometers are used for temperature measurements on a daily basis. Intermediate checks of the working reference measurement standards are performed to verify adequacy between calibration from an external calibration laboratory. The measurements from working weights and thermometers are compared to measurements taken by the reference standard which is traceable to SI or a national Page 55 of 100 ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. standard. The reference weights and thermometers are used solely for verification purposes unless the laboratory can prove that daily use does not adversely affect performance of the reference standard. The laboratory performs intermediate checks of the working weights at least annually. Working thermometers (glass and digital) are checked against the reference thermometer prior to placement in service to establish a correction factor and then rechecked annually(glass) or quarterly(digital) thereafter. The calibration of liquid in glass reference thermometers is verified every 5 years and the calibration of digital reference thermometers is verified annually by an ISO/IEC 17025 accredited calibration laboratory or service provider that provides traceability to a national standard. The calibration of the reference weight(s) is verified every 5 years by an ISO/IEC 17025 accredited calibration laboratory. If criteria for the intermediate checks or recertification is not acceptable, the impact on previously reported results is evaluated using the process for evaluation of nonconforming work(See 4.9). See laboratory SOP ENV-SOP-GBAY-0115 SupportEquipment(most recent revision or replacement)for more information about this process. 5.6.4.2 Reference Materials The laboratory purchases chemical reference materials (also known as stock standards) from vendors that are accredited to ISO 17034 or Guide 34. Purchased reference materials must be received with a Certificate of Analysis (COA) where available. If a reference material cannot be purchased with a COA,it must be verified by analysis and comparison to a certified reference material and/or there must be a demonstration of capability for characterization. COA are reviewed for adequacy and retained by the laboratory for future reference. All prepared standards, reference materials, and reagents are verified to meet the requirements of the test method through routine analyses of quality control samples. The laboratory procedure for traceability and use of these materials is provided in laboratory SOP ENV-SOP-GBAY-0145 Laboratory Supply Procedures (most recent revision or replacement. This SOP includes each of the following requirements: • Procedures for documentation of receipt and tracking. The record of entry includes name of the material,the lot number,receipt date,and expiration date. • Storage conditions and requirements. Reference materials must be stored separately from samples, extracts,and digestates. • Requirements to assure that preparations of intermediate or working solutions are recorded and assigned a unique identification number for tracking. Records of preparation include the lot number of the stock standard(s) used,the type and Page 56 of 100 e> ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. lot number of the solvent, the formulation, date, expiration date, and the preparer's initials. The lot number of the working standards is recorded in the analytical record to provide traceability to the standard preparation record. The preparation record provides traceability to the COA,which is traceable to SI or the national measurement standard. ■ A requirement that the expiration dates of prepared standards may not exceed the expiration date of the parent standard. Standards, reference materials, and reagents are not used after their expiration dates unless it is not possible to procure a new standard and the reliability of the expired material is verified and documented by the laboratory using a procedure approved by corporate quality personnel. Otherwise, the expired material is promptly removed from the work area or clearly labeled as acceptable for qualitative/troubleshooting purposes only. ■ The second source materials used for verification of instrument calibration are obtained from a different manufacturer or may be a different lot from the same manufacturer. • Procedures to check reference materials for degradation and replacement of material if degradation or evaporation is suspected. • Procedures for labeling. At a minimum the container must identify the material, the ID of the material and the expiration date. Original containers should also be labeled with date opened. 5.6.4.3 Intermediate Checks Checks to confirm the calibration status of standards and materials are described in laboratory SOPs. These checks include use of second source standards and reference materials reserved only for the purpose of calibration checks. 5.6.4.4 Transport and Storage The laboratory handles and transports reference standards and materials in a manner that protects the integrity of the materials.Reference standard and material integrity is protected by separation from incompatible materials and/or minimizing exposure to degrading environments or materials. Standards and reference materials are stored separately from samples, extracts, and digestates. All standards are stored according to the manufacturer's recommended conditions. Temperatures colder than the manufacturer's recommendation are acceptable if it does not compromise the integrity of the material (e.g.remains in liquid state and does not freeze solid).In the event a standard is made from more than a single source with different storage conditions, the standard will be stored according to the conditions specified in the analytical method. See the applicable analytical SOPs for specific reference material storage and transport protocols. Page 57 of 100 ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. 5.7 Sampling Sampling refers to the field collection of samples and to subsamples taken by the laboratory for analysis from the field collected sample. Subsampling procedures are included in each test method SOP or a stand-alone SOP to assure the aliquot used for testing is representative of the field collected sample. The requirements in the following subsections apply when field sampling is performed by the laboratory. 5.7.1 Sampling Plans and SOPs When the laboratory performs field collection of samples, sampling is carried out in accordance with a written sample plan prepared by the customer or by the laboratory and by relevant sampling SOPs. These documents are made readily accessible at the sampling location. Sampling plans and SOPs are,whenever reasonable,based on appropriate governing methods and address the factors to be controlled to ensure the validity of the analytical results. 5.7.2 Customer Requested Deviations When the customer requires deviations, additions, or exclusions from the documented laboratory sampling plan and/or procedure,the laboratory records the client's change request in detail with the sampling record, communicates the change to sampling personnel, and includes this information in the final test report. 5.7.3 Recordkeeping The laboratory assures the sampling record includes the sampling procedure used, any deviations from the procedure,the date and time of sampling,the identification of the sampler, environmental conditions (if relevant),and the sampling location. 5.8 Sample Management &Handling 5.8.1 Procedures The laboratory's procedures for sample management and handling are outlined in laboratory SOP ENV-SOP-GBAY-0006,Sample Management and Review of Analytical Requests. The procedures in these SOPs are established to maintain the safe handling and integrity of samples from transport, storage,to disposal and during all processing steps to maintain client confidentiality,and to protect the interests of PAS and its customers. 5.8.1.1 Chain of Custody All samples received by the laboratory must be accompanied with a Chain of Custody (COC) record. The COC provides information about the samples collected and submitted for testing and documents the possession of samples from time of collection to receipt by the laboratory. The COC record must minimally include the following information: • Client name,address,phone number; • Project Reference; Page 58 of 100 'ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT®2021-2023 Pace Analytical Services,LLC. ■ Client Sample Identification(Client ID); • Date,Time,and Location of Sampling; ■ Sampler's Name or Initials; • Matrix; • Type of container,and total number collected for each sample; • Preservatives; • Analyses Requested; • Mode of collection; • Any special instructions;and • The date and time and signature of each sample transfer from time of collection to receipt in the laboratory. When the COC is transported inside the cooler, independent couriers do not sign the COC, the shipping manifests and/or air bills are the records of possession during transport. The shipping manifest must be retained as part of the COC record and included in the test report when required (See Section 5.10.3). A complete and legible COC is required. If the laboratory observes that the COC is incomplete or illegible,the client is contacted for resolution. The COC must be filled out in indelible ink. Personnel correct errors by drawing a single line through the initial entry so the entry is not obscured, entering the correct information, and initialing,and dating the change. 5.8.1.2 Legal Chain of Custody Legal chain of custody is a chain of custody protocol used for evidentiary or legal purposes. The protocol is followed by the laboratory when requested by customer or where mandated by a regulatory program. Legal chain of custody(COC) protocol establishes an intact,continuous record of the physical possession*, storage, and disposal of "samples" which includes sample aliquots,and sample extracts/digestates/distillates. Legal COC records account for all time periods associated with the samples and identifies all individuals who physically handled individual samples.Legal COC begins at the point established by legal authority, which is usually at the time the sample containers are provided by the laboratory for sample collection or when sample collection begins. *A sample is in someone's custody if: • It is in one's physical possession; • It is in one's view after being in one's physical possession; • It has been in one's physical possession and then locked or sealed so that no one can tamper with it;and/or Page 59 of 100 ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. ■ It is kept in a secure area,restricted to authorized personnel only. Refer to laboratory SOP ENV-SOP-GBAY-0006, Sample Management and Review of Analytical Requests for more information. 5.8.2 Unique Identification Each sample is assigned a unique identification number by the laboratory (Lab ID) after the sample has been checked and accepted by the laboratory in accordance with the laboratory's sample acceptance policy (See 5.8.3). The Lab ID is affixed to the sample container using a durable label. The unique identification of samples also applies to subsamples,and prepared samples,such as extracts,digestates, etc. The lab ID is linked to the field ID (client ID) in the laboratory's record. Both IDs are linked to the testing activities performed on the sample and the documentation records of the test. Also see 5.8.4. 5.8.3 Sample Receipt Checks and Sample Acceptance Policy The laboratory checks the condition and integrity of samples on receipt and compares the labels on the sample containers to the COC record. Any problem or discrepancy is recorded. If the problem impacts the suitability of the sample for analysis or if the documentation is incomplete,the client is notified for resolution.Decisions and instructions from the client are maintained in the project record. 5.8.3.1 Sample Receipt Checks The following checks are performed: ■ Verification that the COC is complete and legible. • Verification that each sample's container label includes the client sample ID,the date and time of collection and the preservative in indelible ink. ■ The container type and preservative are appropriate for each test requested. • Adequate volume is received for each test requested. • Visual inspection for damage or evidence of tampering. • Visual inspection for presence of headspace in VOA vials. (VOA = volatile organic analysis). • Thermal Preservation:Generally,for chemical testing methods for which thermal preservation is required,temperature on receipt is acceptable if the measurement is above freezing but <6°C. The requirements for thermal preservation vary based on test method or by regulatory program. For example, for microbiology, temperature on receipt is acceptable if the measurement is <10°C. Refer to the laboratory's SOP for sample receipt for specific requirements. For samples that are hand-delivered to the laboratory immediately after sample collection, there must be evidence that the chilling process began immediately after sample Page 60 of 100 °ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. collection and prior to delivery of the samples to the laboratory or service center, such as arrival of the samples on ice. • Chemical Preservation ■ Holding Time: Sample receiving personnel are trained to recognize tests where the holding time is 48 hours or less and to expedite the log-in of these samples. Except for tests with immediate holding times (15 minutes from time of collection or less), when samples are received out of hold, the laboratory will notify the client and request instruction.If the decision is made to proceed with analysis,the final test report will include notation of this instruction. 5.8.3.2 Sample Acceptance Policy The laboratory maintains a sample acceptance policy in accordance with regulatory guidelines to clearly establish the circumstances in which sample receipt is accepted or rejected. When receipt does not meet criteria for any one of these conditions, the laboratory must document the noncompliance, contact the customer, and either reject the samples or fully document any decisions to proceed with testing.In accordance with regulatory specifications, test results associated with receipt conditions that do not meet criteria are qualified in the final test report. All samples received must meet each of the following criteria: • Be listed on a complete and legible COC; • Be received in properly labeled sample containers; • Be received in appropriate containers that identify preservative; • The COC must include the date and time of collection for each sample; • The COC must include the test method requested for each sample; • Be in appropriate sample containers with clear documentation of the preservatives used; • Be received within holding time.Any samples received beyond the holding time will not be processed without prior customer approval; • Have sufficient sample volume to proceed with the analytical testing. If insufficient sample volume is received,analysis will not proceed without customer approval;and • Be received within appropriate temperature ranges unless program requirements or customer contractual obligations mandate otherwise.The cooler temperature is recorded directly on the COC. Samples that are delivered to the laboratory immediately after collection are considered acceptable if there is evidence that the chilling process has been started. For example, by the arrival of the samples on ice. If samples arrive that Page 61 of 100 ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. are not compliant with these temperature requirements, the customer will be notified. The analysis will NOT proceed unless otherwise directed by the customer. If less than 72 hours remain in the hold time for the analysis, the analysis may be started while the customer is contacted to avoid missing the hold time. Data associated with any deviations from the above sample acceptance policy requirements will be appropriately qualified. 5.8.4 Sample Control and Tracking The samples are controlled and tracked using the Laboratory Information Management System (LIMS). The LIMS stores information about the samples and project. The process of enteringinformation into the LIMS is called log-in and these procedures are described in g laboratory SOP ENV-SOP-GBAY-0006, Sample Management and Review of Analytical Requests. After log-in, a label is generated and affixed to each sample container. Information on this label, such as the lab ID,links the sample container to the information in LIMS. At a minimum,the following information is entered during log-in: • Client Name and Contact Information; • The laboratory ID linked to the client ID; • Date and time of sample collection; • Date and time of sample receipt; • Matrix;and • Tests Requested. 5.8.5 Sample Storage,Handling, and Disposal The laboratory procedures for sample storage,handling and disposal are detailed in laboratory SOPs ENV-SOP-GBAY-0006, Sample Management and Review of Analytical Requests and ENV- SOP-GBAY-0126, Waste Handling and Management(most current revision(s) or replacement(s). 5.8.5.1 Sample Storage The samples are stored according to method and regulatory requirements as per test method SOPs. Samples are stored away from all standards, reagents, or other potential sources of contamination and stored in a manner that prevents cross contamination.Volatile samples are stored separately from other samples.All sample fractions, extracts,leachates,and other sample preparation products are stored in the same manner as actual samples or as specified by the analytical method. Refrigerated storage areas are maintained at 5_6°C (but not frozen) and freezer storage areas are maintained at <-10°C, unless otherwise required per method or program. The temperature of each storage area is checked and documented at least once for each day of use.If the temperature falls outside the acceptable limits, then corrective actions are taken and appropriately documented. The laboratory is operated under controlled access protocols to ensure sample and data integrity.Visitors must register at the front desk and be properly escorted while on-site. Samples are taken to the appropriate storage location immediately after sample receipt and log-in procedures are completed. All sample storage areas have Page 62 of 100 ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. limited access. Samples are removed from storage areas by designated personnel and returned to the storage areas as soon as possible after the required sample quantity has been taken. 5.8.5.2 Sample Retention and Disposal The procedures used by the laboratory for sample retention and disposal are detailed in laboratory SOP ENV-SOP-GBAY-0126, Waste Handling and Management. In general,unused sample volume and prepared samples such as extracts,digestates, distillates and leachates (samples) are retained by the laboratory for the timeframe necessary to protect the interests of the laboratory and the customer. Samples may be stored at ambient temperature when all analyses are complete, the hold time is expired, the report has been delivered, and/or when allowed by the customer or program. Samples requiring storage beyond the minimum sample retention time due to special requests or contractual obligations may be stored at ambient temperature unless the laboratory has a capacity and their presence does not compromise the integrity of other samples. After this period expires, non-hazardous samples are properly disposed of as non- hazardous waste. The preferred method for disposition of hazardous samples is to return the excess sample to the customer. 5.9 Assuring the Quality of Test Results 5.9.1 Quality Control(QC) Procedures The laboratory monitors the validity and reliability of test results using quality control (QC) samples that are prepared and analyzed concurrently with field samples in the same manner as field samples. QC results are always associated to and reported with the field samples they were prepared and analyzed with from the same preparation or analytical batch. See the glossary for definition of preparation and analytical batch. The results of QC performed during the testing process are used by the laboratory to assure the results of analysis are consistent, comparable,accurate, and/or precise within a specified limit. When the results are not within acceptance criteria or expectations for method performance, correction and corrective action(s) are taken. These actions may include retesting or reporting of data with qualification to alert the end user of the situation. Other QC measures performed include the use of certified reference materials (see 5.6.4), participation in interlaboratory proficiency testing(see 5.9.1.2),verification that formulae used for reduction of data and calculation of results is accurate (see 5.9.3),on-going monitoring of environmental conditions that could impact test results (see 5.3.2), and evaluation and verification of method selectivity and sensitivity(see 5.4.5). QC results are also used by the laboratory to monitor performance statistical trends over time and to establish acceptance criteria when no method or regulatory criteria exist.(See 5.9.1.1.9)). 5.9.1.1 Essential QC Although the general principles of QC for the testing process apply to all testing,the QC protocol used for each test depends on the type of test performed. Page 63 of 100 aceAnalytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. QC protocol used by the laboratory to monitor the validity of the test are specified in test method SOPs. The SOP includes QC type, frequency, acceptance criteria, corrective actions,and procedures for reporting of nonconforming work. These requirements in the SOP conform to the reference method and any applicable regulations or certification and accreditation program requirement for which results of the test are used. When a project requires more stringent QC protocol than specified in the SOP,project specification is followed. When the project requires less stringent QC protocol, the project specification may be followed as an authorized departure from the SOP when the project specifications meet the requirements in the mandated method and any regulatory compliance requirements for which the data will be used. The following are examples of essential QC for Chemistry: 5.9.1.1.1 Second Source Standard (ICV/QCS) The second source standard is a standard obtained from a different vendor than the vendor of the standards used for calibration or it may be from a different lot from the same vendor when there are limited vendors that offer the material. It is a positive control used to verify the accuracy of a new calibration relative to the purity of the standards used for calibration. This check is referred to in test method and quality system standards as the initial calibration verification (ICV) or quality control sample (QCS). The second source standard is analyzed immediately after the calibration and before analysis of any samples. When the ICV is not within acceptance criteria,a problem with the purity or preparation of the standards may be indicated. 5.9.1.1.2 Continuing Calibration Verification(CCV) CCV results are used to determine if the analytical response has significantly changed since initial calibration. If the response of the CCV is within criteria, the calibration is considered valid. If not, there is a problem that requires further investigation. Actions taken are technology and method specific. 5.9.1.1.3 Method Blank(MB) / Other Blanks A method blank is a negative control used to assess for contamination during the prep/analysis process. The MB consists of a clean matrix, similar to the associated samples that is known to be free of analytes of interest. The MB, unless otherwise specified by the test method, is processed with and carried through all preparation and analytical steps as the associated samples. In general, contamination is suspected when the target analyte is detected in the MB above the reporting limit. Some programs may require evaluation of the MB to 1/2 the reporting limit or the detection limit. When contamination is evident, the source is investigated, and corrections are taken to reduce or eliminate it. Page 64 of 100 ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. Analytical results associated with MB that does not meet criteria are qualified in the final test report. Other types of blanks that serve as negative controls in the process may include: ■ Trip Blanks (VOA) ■ Storage Blanks ■ Equipment Blanks ■ Field Blanks • Calibration Blanks • Cleanup Blanks • Instrument Blanks 5. .1.1. Laboratory Control Sample (LCS) The LCS is positive control used to measure the accuracy of process in a blank matrix. The LCS is spiked by the laboratory with a known amount of analyte. The spike is a standard solution that is pre-made or prepared from a certified reference standard.Like the MB,unless otherwise specified in the test method, the LCS is processed with and carried through all preparation and analytical steps as the associated samples. When the percent recovery(%R) of the LCS is within the established control limit, sufficient accuracy has been achieved. If not, the source of the problem is investigated and corrected, and the procedure may be repeated. Analytical results associated with LCS that does not meet criteria are qualified in the final test report. 5. .1.1. Matrix Spike (MS) and Matrix Spike Duplicate (MSD) Matrix spikes measure the effect the sample matrix has on precision and accuracy of the determinative test method. The MS and MSD are replicates of a client sample that is spiked with known amount of target analyte. • Due to the heterogeneity of matrices even of the same general matrix type, matrix spike results mostly provide information on the effect of the matrix to the client whose sample was used and on samples of the same matrix from the same sampling site. Therefore, MS should be client-specific when the impact of matrix on accuracy and precision is a project data quality objective. When there is not a client-specified MS for any sample in the batch, the laboratory randomly selects a sample from the batch; the sample selected at random is called a"batch"matrix spike. The MS/MSD results for percent recovery and relative percent difference are checked against control limits. Because the performance of matrix spikes is matrix-dependent, the result of matrix spikes is not used to determine the acceptability of the test. Page 65 of 100 "ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. 5.9.1.1.6 Sample Duplicate (SD) A sample duplicate is a second replicate of sample that is prepared and analyzed in the laboratory along another replicate. The SD is used to measure precision. The relative percent difference between replicates are evaluated against the method or laboratory derived criteria for relative percent difference (RPD), when this criterion is applicable. If RPD is not met,associated test results are reported with qualification. 5.9.1.1.7 Surrogates Surrogates are compounds that mimic the chemistry of target analytes but are not expected to occur naturally in real world samples. Surrogates are added to each sample and matrix QC samples (MS, MSD, SD) at known concentration to measure the impact of the matrix on the accuracy of method performance. Surrogates are also added to the positive and negative control samples (MB, LCS) to evaluate performance in a clean matrix, and included in the calibration standards and calibration check standards. The percent recovery of surrogates is evaluated against method- specified limits or statistically derived in-house limits. Project- specific limits and/or program-specific limits are used when required. Results with surrogate recovery out of limits in samples are reported with qualification. Samples with surrogate failures can also be re-extracted and/or re-analyzed to confirm that the out-of- control value was caused by the matrix of the sample and not by some other systematic error. 5.9.1.1.8 Internal Standards Internal Standards are compounds not expected to occur naturally in field samples. They are added to every standard and sample at a known concentration prior to analysis for the purpose of adjusting the response factor used in quantifying target analytes. The laboratory follows specific guidelines for the treatment of internal standard recoveries and further information can be found in the applicable laboratory SOP. 5.9.1.1.9 QC Acceptance Criteria and Control Limits The QC acceptance criteria are specified in test method SOPs. The criteria in the SOP are based on the requirements in the published test method or regulatory program. When there are no established acceptance criteria, the laboratory develops acceptance criteria in accordance with recognized industry standards. Some methods and programs require the laboratory to establish control limits for LCS, MS/MSD, and surrogate evaluation using historical data. Laboratory developed limits are referred to as "in- Page 66 of 100 *ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. house" control limits. In-house control limits represent ± 3 Standard Deviations (99% confidence level) from the average recovery of at least 20 data points generated using the same preparation and analytical procedure in a similar matrix. See laboratory SOP ENV-SOP-GBAY-0116, Control Charting and Trend Analysis for more information about the procedures used to establish in-house control limits. 5.9.1.2 Proficiency Testing(PT) The laboratory participates in interlaboratory proficiency testing (PT) studies to measure performance of the test method and to identify or solve analytical problems. PT samples measure laboratory performance through the analysis of unknown samples provided by an external source. The PT samples are obtained from accredited proficiency testing providers (PTP) and handled as field samples which means they are included in the laboratory's normal analytical processes and do not receive extraordinary attention due to their nature. The laboratory does not share PT samples with other laboratories, does not communicate with other laboratories regarding current PT sample results during the duration of the study, and does not attempt to obtain the assigned value of any PT sample from the PT provider. The laboratory investigates and implements corrective action whenever PT results are scored unacceptable by the PT provider. The frequency of PT participation is based on the certification and accreditation requirements held by the laboratory. 5.9.2 QC Corrective Action When the results of QC are not within acceptance criteria or expectations for method performance, correction and corrective action(s) are taken per the specifications in the test method SOP. These actions may include retesting or reporting of data with qualification to alert the end user of the situation. 5.9.3 Data Review The laboratory uses a tiered system for data review. The tiered process provides sequential checks to verify data transfer is complete; manual calculations, if performed, are correct, manual integrations are appropriate and documented, calibration and QC requirements are met,appropriate corrective action was taken when required,test results are properly qualified, process and test method SOPs were followed,project specific requirements were met,when applicable,and the test report is complete. The sequential process includes three tiers referred to as primary review, secondary review, and administrative/completeness review. Detailed procedures for the data review process are described in laboratory SOP ENV-SOP- GBAY-0120,Data Review and Final ReportProcess. The general expectations for the tiered review process are described in the following sections: Page 67 of 100 'ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. 5.9.3.1 Primary Review Primary review is performed by the individual that performed the task. All laboratory personnel are responsible for review of their work product to assure it is complete, accurate,documented,and consistent with policy and SOPs. Checks performed during primary review include but are not limited to: ■ Verification that data transfer and acquisition is complete • Manual calculations,if performed,are documented and accurate • Manual integrations,if performed,are documented and comply with SOP ENV- SOP-CORQ-006 Manual Integration(most recent revision or replacement) ■ Calibration and QC criteria were met, and/or proper correction and corrective actions were taken, and data and test results associated with QC and criteria exceptions are properly qualified • Work is consistent with SOPs and any other relevant instructional document such as SWI,program requirements,or project QAPP. 5.9.3.2 Secondary Review Secondary review is performed by a qualified peer or supervisor. Secondary review is essentially a repeat of the checks performed during primary review by another person. In addition to the checks of primary review, secondary review includes chromatography review to check the accuracy of quantitative analyte identification. 5.9.3.3 Completeness Review Completeness review is an administrative review performed prior to release of the test report to the customer. Completeness review verifies that the final test report is complete and meets project specification. This review also assures that information necessary for the client's interpretation of results are explained in the case narrative or footnoted in the test report. 5.9.3.4 Data Audits In addition to the 3-tier data review process, test reports may be audited by local quality personnel to verify compliance with SOPs and to check for data integrity, technical accuracy,and regulatory compliance. These audits are not usually done prior to issuance of the test report to the customer. The reports chosen for the data audits are selected at random. If any problems with the data or test results are found during the data audit,the impact of the nonconforming work is evaluated using the process described in Section 4.9. Also see Section 4.14 for internal audits. 5.9.4 Calibration Certificates The laboratory does not perform calibration activities for its customers and calibration certificates are not offered or issued. Page 68 of 100 'ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. 5.9.5 Opinions and Interpretations The laboratory provides objective data and information to its customers of sufficient detail for their interpretation and decision making. Objective data and information are based solely on fact and does not attempt to explain the meaning(interpret) or offer a view or judgement (opinion). Sometimes the customer may request the laboratory provide opinion or interpretation to assist them with their decisions about the data. When opinions and interpretations are included in the test report, the laboratory will document the basis upon which the opinions and interpretations have been made and clearly identify this content as opinion or interpretation in the test report. Examples of opinion and interpretation include but are not limited to: ■ The laboratory's viewpoint on how a nonconformance impacts the quality of the data or usability of results. ■ The laboratory's judgment of fulfillment of contractual requirements. • Recommendations for how the customer should use the test results and information. • Suggestions or guidance to the customer for improvement. When opinions or interpretations are verbally discussed with the customer, the content of these conversations is summarized by the laboratory and kept in the project record. 5.9.6 Subcontractor Reports When analytical work has been subcontracted to an organization external to PAS, the test report from the subcontractor is included in its entirety as an amendment to the final test report. Test results performed by multiple locations within the PAS network may be merged into a single test report. The test report issued clearly identifies the location and address of each network location that performed testing,and which tests they performed. (See 5.10.2) 5.9.7 Electronic Transmission of Results When test results and/or reports are submitted to the customer through electronic transmission, the procedures established in this manual for confidentiality and protection of data apply. 5.9.8 Format of Test Reports The test formats offered by the laboratory are designed to accommodate each type of analytical test method carried out by the laboratory and to minimize the possibility of misunderstanding or misuse of analytical results. The format of electronic data deliverables (EDD) follow the specifications for the EDD. 5.9.9 Amendments to Test Reports Test reports that are revised or amended by the laboratory after date of release of the original final test report to the customer are issued as a new test report that is clearly identified as an amendment or revision and that includes a reference to the originally issued final test report. The customer is the organization doing business with PAS external to PAS. Page 69 of 100 'ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. Changes made to test results and data before the final test report is issued to the customer are not amendments or revisions, these are corrections to errors found during the laboratory's data verification and review process. The laboratory's procedure for report amendments and revision are outlined in laboratory SOP ENV-SOP-GBAY-0120,Data Review and Final Report Process. 5.10 Reporting 5.10.1 General Requirements The laboratory reports results of testing in a way that assures the results are clear, and unambiguous.All data and results are reviewed prior to reporting to assure the results reported are accurate and complete. Test results are summarized in test reports that include all information necessary for the customer's interpretation of the test results. Additional information necessary to clarify the data or disclose nonconformance, exceptions,or deviations that occurred during the analytical process are also reported to the customer in the test report. The specifications for test reports and EDD are established between the laboratory and the customer at the time the request est for analytical services is initiated. The rep ort y specifications include the test report format, protocol for the reporting limit (RL), conventions for the reporting of results less than the limit of quantitation (LOQ), and specification for the use of project or program specific data qualifiers. Information about review of analytical service requests is provided in Section 4.4. 5.10.2 Test Reports: Required Items Test Reports are prepared by the laboratory at the end of the testing process. The format of the report depends on the level of reporting requested by the customer. The laboratory offers a variety of standardized test report formats and can provide custom test report formats,when necessary. The level of detail required in the test report depends on the customer's needs for data verification, validation, and usability assessments that occur after the laboratory releases the test report to the customer. The test report formats offered by the laboratory provide gradient levels of detail to meet the unique needs of each customer. The laboratory project manager helps the customer select the test report format that best meets their needs. When a specific report format or protocol is required for a regulatory or program compliance,the laboratory project manager must ensure the test report selected meets those requirements. Every test report issued by the laboratory includes each of the following items: a) Title b) Name and phone number of a point of contact from the laboratory issuing the report. c) Name and address of the laboratory where testing was performed. When testing is done at multiple locations within network (IRWO), the report must clearly identify which network laboratory performed each test and must include the physical address of each laboratory. d) Unique identification of the test report and an identifier on each page of the report to link each page to the test report and clear identification of the end of the report.

Each subsection is stand-alone, meaning the requirements for the quality management system in each subsection only apply to the program referenced. Additionally,only program requirements for the quality management system that are more stringent than the content of the main body of the manual are included. 8.1 DoD/DoE PAS-Green Bay maintains accreditation for DoD/DoE Environmental Laboratory Approval Program(ELAP) This addendum outlines additional policies and processes established by this laboratory to maintain compliance with DoD/DOE program specific requirements as outlined in the DoD/DoE Consolidated Quality Systems Manual (QSM) for Environmental Laboratories. The QSM incorporates ISO/IEC 17025 and the TNI Standard and includes additional program-specific requirements for laboratories that perform analytical testing services for DoD and DoE and which must be followed for DoD / DoE projects. Section 4.2.5: Supporting Documents Technical SOPs used for DoD/DoE testing must also include instructions for equipment and instrument maintenance, computer software/hardware,and troubleshooting. The review frequency for technical SOPs used for DoD/DoE testing is annual, instead of every 2 years. Section 4.4: Review of Analytical Service Requests If the DoD/DoE customer requests a statement of conformity, the standard used for the decision rule must be communicated to and agreed on with the customer and identified in the final test report. Laboratory requests to deviate from the requirements specified in the DoD/DoE QSM must be requested on a project-basis and include technical justifications for the deviation. These requests are submitted to and approved by the DoD/DoE project chemist or contractor, however named, in addition to the PAS client. For DoD / DoE projects, will also seek clarification from the customer when the customer has requested an incorrect, obsolete or improper method for the intended use of data; the laboratory needs to depart from its test method SOP in order to meet project-specific data quality objectives; information in project planning documents is missing or is unclear, Section 4.5: Subcontracting In addition to written client approval of any subcontractor for testing,the customer is notified of the laboratory's intent to use a subcontractor for any management system element (such as data review, data processing, project management or IT support) and consent for subcontracting is obtained approved in writing by the DoD/DoE customer and record of consent kept in the project record. Section 4.6: Purchasing and Supplies The laboratory procedure for records of receipt of materials and supplies used in testing also include a specification to record the date opened(DoE only). Page 98 of 100 ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. Section 4.9.3: Nonconforming Work The laboratory's procedure for client notification includes the 15-business day DoD/DOE timeframe for notification of the problem and the 30-business day timeframe for submission of the corrective action plan or corrective actions taken.This procedure also includes the DoD/DoE requirement for AB notification of discovery. Section 4.13: Control of Records Technical Records: The laboratory's procedure for logbooks includes measures to prevent the removal of or addition of pages to the logbook(applies to both hardcopy and electronic). Hardcopy logbooks are version controlled, pre-numbered and bound. Initials and entries and are signed or initialed and dated by the person making the entry and the entry is made at the time the activity is performed and in chronological order. Each page of the logbook must be closed by the last person making the entry on the page. Closure is recorded by the initial and date of the person making the last entry. Section 5.4.5.3.3: Limit of Detection For DoD/DoE the LOD is an estimate of the minimum amount of an analyte that can be reliably detected by an analytical process. For clarification, the LOD is the analyte concentration necessary to distinguish its presence from its absence. The LOD may be used as the lowest concentration for reliably reporting a non-detect(ND). The LOD is specific to each suite of analyte,matrix,and method including sample preparation. After each DL determination,the laboratory establishes the LOD by spiking a quality system matrix at a concentration of least 2X but no greater than 4X the DL (i.e. 2X DL <_ LOD Spike <_ 4X DL). The spike concentration establishes the LOD and the concentration at which the LOD is verified. The LOD is established during method validation and after major changes to the analytical system or procedure that affects sensitivity of analysis or how the procedure is performed. An LOD study is not required for any component for which spiking solutions or quality control samples are not available. Additionally,an LOD study is not required if the laboratory does not report data below the LOQ. The LOD must be verified on a quarterly basis. Each preparation method listed on the scope of accreditation must have quarterly LOD verifications; however, verification of all possible combinations of preparation and clean-up techniques is not required. Where LOD verifications are not performed on all combinations, the LOD verification is based on the worst-case combination (preparation method with all applicable cleanup steps). The laboratory's procedure for LOD determination and verification is detailed in laboratory SOP ENV-SOP-GBAY-0106 Determination of the LOD and LQQ (most recent revision or replacement). Section 5.4.5.3.4: Limit of Quantitation For DoD/DoE, the LOQ is established for each analyte-matrix-method combination, including surrogates. When an LOD is determined or verified by the laboratory,the LOQ must be above the LOD [DL<LOD<LOQ]. At a minimum,the LOQ must be verified quarterly;however,verification of all possible combinations of preparation and clean-up techniques is not required. Where LOQ verifications are not performed Page 99 of 100 *ace Analytical LABORATORY QUALITY MANUAL Pace Analytical Services,LLC COPYRIGHT©2021-2023 Pace Analytical Services,LLC. on all combinations,the LOQ verification on the worst-case combination (preparation method with all applicable cleanup steps). The laboratory's procedure for LOQ determination and verification is detailed in laboratory SOP ENV-SOP-GBAY-0106 Determination of the LOD and LOQ (most recent revision or replacement). Section 5.4.7: Control of Data The laboratory will assure LIMS passwords are changed at least once per year. An audit of the LIMS will be incorporated into the laboratory's annual internal audit schedule. The laboratory will have procedures in place to notify DoD/DoE customers of changes to LIMS software or hardware configurations that may impact the customer's integrity of electronic data Section 5.9.1: Quality Control For DoD/DoE,storage blanks are essential QC to monitor the storage of samples for volatile organic analysis (VOA). The laboratory's SOP for storage of VOA samples must include a contamination monitoring program based on the performance of storage blanks. (See QSM 5.3.3) Section 5.8.5: Sample Disposal For DoE projects, the record of disposal must also include how the sample was disposed and the name of the person that performed the task. Appendix E: Support Equipment Calibration Mechanical Volumetric Pipette: In addition to the quarterly verification check, pipettes used for DoD/DoE projects are checked daily before use using the same procedure and criteria specified for the quarterly check. Water Purification System: The performance of the water purification system is checked daily prior to use in accordance with laboratory SOP ENV-SOP-GBAY-0127 Use and Maintenance of Water Purification Systems(most recent revision or replacement). Radiological Survey Equipment: The performance of the radiological survey equipment is checked daily prior to use in accordance with laboratory SOP ENV-SOP-GBAY-0158 ECD Management(most recent revision or replacement). Additional: (DoE): Section 6.0 of the QSM outlines additional management system requirements for the management of hazardous and radioactive materials management and health and safety practices. The laboratory,if approved for DoE,will work with the PAS Health and Safety Director to establish plans, policies and procedures that conform to these comprehensive specifications and incorporate these documents into the quality management system.

When dissolved constituents are required, samples must be filtered and acid-preserved prior to analysis. Dissolved samples are typically acid digested prior to analysis. Acid digestion prior to centrifuging and analysis is required for aqueous and solid samples for which total (acid-leachable) elements are required. 1.1 Target Analyte List Isotope Element Symbol CASRN 27 Aluminum Al 7429-90-5 121 Antimony Sb 7440-36-0 75 Arsenic As 7440-38-2 137 Barium Ba 7440-39-3 9 Beryllium Be 7440-41-7 10 Boron B 7440-42-8 111 Cadmium Cd 7440-43-9 43 Calcium Ca 7440-70-29 133 Cesium Cs 7440-46-2 52 Chromium Cr 7440-47-3 59 Cobalt Co 7440-48-4 63 Copper Cu 7440-50-8 54 Iron Fe 7439-89-6 7 Lithium Li 7439-93-2 208 Lead Pb 7439-92-1 25 Magnesium Mg 7439-95-4 55 Manganese Mn 7439-96-5 201 Mercury Hg 7439-97-6 95 Molybdenum Mo 7439-98-7 60 Nickel Ni 7440-02-0 105 Palladium Pd 7440-06-4 31 Phosphorous P 7723-14-0 195 Platinum Pt 7440-05-3 39 Potassium K 7440-09-7 78 Selenium Se 7782-49-2 28 Silicon Si 7440-21-3 - 107 Silver Ag 7440-22-4 23 Sodium Na 7440-23-5 88 Strontium Sr 7440-24-6 205 Thallium TI 7440-28-0 118 Tin Sn 7440-31-5 47 Titanium Ti 7440-32-6 182 Tungsten W 7440-33-7 238 Uranium U 7440-61-1 51 Vanadium V 7440-62-2 Any printed copy of this SOP and all copies of this SOP outside of Pace are uncontrolled copies.

A number of methods are recommended in SW846 and EPAsamplepreparation/digestion 200.8 for the of various matrices for tr ace metals analysis by ICPMS. Applicable analytes are listed in the Target Analyte List. 2.2 Methods 6020B/200.8 describe the multi-elemental determination of analytes by ICPMS. The method measures ions produced by a radio frequency inductively coupled argon plasma. Analyte species originating in a liquid are nebulized and the resulting aerosol transported by argon gas into the plasma torch. The ions produced are entrained in the plasma gas and introduced, by means of an interface, into a mass spectrometer. The ions produced in the plasma are sorted according to their mass-to-charge ratios and quantified with a channel electron multiplier. Interferences must be assessed, and valid corrections applied, or the data must be flagged to indicate problems. Interference correction must include compensation for background ions contributed by the plasma gas, reagents, and constituents of the sample matrix as well as isobaric elemental corrections. 3.0 INTERFERENCES 3.1 Isobaric Elemental Interferences — Isobaric elemental interferences result when isotopes of different elements have the same nominal mass-to-charge ratio and cannot be resolved with the instruments spectrometer. One way to solve this problem is to measure a different isotope for which there is no interference. Alternatively, one can monitor another isotope of the element and subtract an appropriate amount from the element being analyzed, using known isotope ratio information. Corrections for most of the common elemental interferences are programmed into the software. 3.2 Isobaric Polyatomic Interferences — Isobaric polyatomic interferences result when ions containing more than one atom have the same nominal mass-to-charge ratio as an analyte of interest and cannot be resolved by the instrument's spectrometer. An example includes CIO+ (mass 51), which interferes with V, and must be corrected by measuring CIO+ at mass 53. When possible, an interference free isotope should be chosen for measurement. Any printed copy of this SOP and all copies of this SOP outside of Pace are uncontrolled copies. Uncontrolled copies are not tracked or replaced when new versions are released or the SOP is made obsolete. Users of the SOP should verify the copy in possession is the current version of the SOP before use.

Nebulization and transport processes can be affected if a matrix component causes a change in surface tension or viscosity. Changes in matrix composition can cause significant signal suppression or enhancement. Dissolved solids can deposit on then nebuli zer zer tip of a pneumatic nebulizer and on the interface skimmers (reducing the orifice size and the instrument performance). Total solid levels below 0.2% (2,000 mg/L) have been currently recommended to minimize solid deposition. An internal standard can be used to correct for physical interferences if it is carefully matched to the analyte so that the two elements are similarly affected by matrix changes. 3.4 Memory interferences can occur when there are large concentration differences between samples or standards which are analyzed sequentially. Sample deposition on the sampler and skimmer cones, spray chamber design, and the type of nebulizer affects the extent of the memory interferences which are observed. The rinse period between samples must be long enough to eliminate significant memory interference. 3.5 It is important to note that matrix matching acid concentrations and compositions between standards, blanks, and samples is required and cannot be ignored. 3.6 Chromic acid should never be used to clean any container used in ICPMS analysis. 3.7 Borosilicate glass in sample containers can lead to interference of Boron concentrations in samples. This is also true of volumetric flasks, thus when dilution in the flask is complete the standards must be removed as soon as possible from the dilution container and placed into a clean plastic container. 4.0 DEFINITIONS Refer to the Laboratory Quality Manual for a glossary of common lab terms and definitions. 5.0 HEALTH AND SAFETY The toxicity or carcinogenicity of each chemical material used in the laboratory has not been fully established. Each chemical should be regarded as a potential health hazard and exposure to these compounds should be as low as reasonably achievable. The laboratory maintains documentation of hazard assessments and OSHA regulations regarding the safe handling of the chemicals specified in each method. Safety data sheets for all hazardous chemicals are available to all personnel. Employees must abide by the health, safety and environmental (HSE) policies and procedures specified in this SOP and in the Pace Chemical Hygiene/Safety Manual. Personal protective equipment (PPE) such as safety glasses, gloves, and a laboratory coat must be worn in designated areas and while handling samples and chemical materials to protect against physical contact with samples that contain potentially hazardous chemicals and exposure to chemical materials used in the procedure.

When working with acids, always add acid to water to prevent violent reactions. Any processes that emit large volumes of solvents (evaporation/concentration processes) must be in a hood or apparatus that prevents employee exposure. Contact your supervisor or local HSE coordinator with questions or concerns regarding safety protocol or safe handling procedures for this procedure. 6.0 SAMPLE COLLECTION, PRESERVATION, HOLDING TIME, AND STORAGE Requirements for container type, preservation, and field quality control (QC) for the common list of test methods offered by Pace are included in the laboratory's quality manual. Samples should be collected in accordance with a sampling plan and procedures appropriate to achieve the regulatory, scientific, and data quality objectives for the project. The laboratory will provide containers for the collection of samples upon client request for analytical services. Bottle kits are prepared in accordance with laboratory SOP ENV-SOP-GBAY-0007 Bottle Preparation (most recent version or replacement). 6.1 All sample containers must be HDPE, glass, or Teflon. The containers are purchased pre-cleaned and documented to be contaminant free. Where applicable, the bottle ware is demonstrated to be fee of target analytes. When bottle ware not originating from the lab is used, the data may be qualified with either one or both of the following data qualifiers: 6.1.1 Sample field preservation does not meet EPA or method recommendations for this analysis. 6.1.2 Sample container did not meet EPA or method requirements. 6.2 Aqueous Samples 6.2.1 Dissolved samples must be filtered through a 0.45-pm pore diameter membrane filter at the time of collection or as soon after as practically possible. The laboratory can perform the filtration if the step was not performed in the field. The filtrate is then preserved to a pH<2 with nitric acid, acid not to exceed 2% of the container capacity. 6.2.2 Total samples are preserved to a pH<2 with nitric acid, acid not to exceed 2% of the container capacity. Note: Aqueous samples that react violently to the addition of acid maybe collected without chemical preservation with proper variances approved by the regulatory authority. The responsibility of requesting this variance lies with the sample collector. Note: Samples may be preserved in the lab. The samples may not be processed until 24 hours after preservation with a pH test of <2, unless otherwise noted on the data. Samples that do not attain a pH<2 or samples that are filtered in the lab must be flagged with P4. Any printed copy of this SOP and all copies of this SOP outside of Pace are uncontrolled copies.

Thermal preservation is checked and recorded on receipt in the laboratory in accordance with laboratory SOP ENV-SOP-GBAY-0006 Sample Management (most recent revision or replacement). Chemical preservation is checked and recorded at time of receipt or prior to sample preparation. Shipments of soil and water samples to the laboratory require thermal preservation in the form of cubed, block or dry ice. At the time of laboratory receipt, proper thermal preservation is checked by measuring the temperature of melt water or when provided the temperature blank. The Pace Analytical acceptable temperature range is 0 to 6°C (or 5.-10 for dry ice for biota samples). All QAPjP and regulatory authority requirements become priority over this requirement. After receipt, aqueous samples are stored at room temperature, solid samples are stored at 0 - 6°C, and biota samples are stored at -10°C or less until sample preparation. Prepared samples (digestates)are stored at room temperature until sample analysis. After analysis, unless otherwise specified in the analytical services contract, samples are retained for 21 days from date of final report and then disposed of in accordance with Federal, State, and Local regulations.

Rnf42 ace Analytical TEST METHOD STANDARD OPERATING PROCEDURE TITLE: Determination of Trace Metals in Waters and Wastes By Inductively Coupled Plasma Mass Spectroscopy TEST METHOD SW-846 6020E and EPA 200.8 ISSUER: Pace ENV—Green Bay Quality—GBAY I COPYRIGHT©2021 Pace Analytical Services, LLC 8.0 REAGENTS AND STANDARDS 8.1 Standards are used in the tuning of the instrument through the calibration, calibration verification, sample analysis, and continuing calibration verification. Standard solutions include: instrument tuning solutions, calibration and calibration check standards, ICSA/AB, internal standards, low level check standards (LLC, CRI, or CRDL), and spike standards. Please see Table 8.7 for a list of working standards. Table 8.6 lists the directions to making intermediate standards from the stock standards listed in Table 8.5. 8.1.1 Mass Spectrometer Tuning Solution: A solution containing elements representing all of the mass regions of interest (for example, 10 pg/L of 23, 24, 25Mg and 206, 207, 208Pb) must be prepared to verify that the mass resolution and mass calibration of the instrument are within the required specifications. This solution is also used to verify that the instrument has reached thermal stability. 8.1.2 Cross Calibration Solution (X Cal): contains 50 ppb of all method analyte elements (with the exception of Li, at 100ppb). This solution is used to calculate the concentration when the detector changes from pulse mode to analog mode. This enables a large linear range while protecting the detector. 8.1.3 Calibration Standards: These are an increasing gradient of concentration for the analytes of interest. These can be made in the laboratory or purchased from commercial suppliers. 8.1.4 Linear Range (LR): These standards may be a mix or single element standard used to verify the upper limit of the instrument's working range. 6020B requires that the upper limit of the range be verified every calibration. If the LDR is not verified above the high point of the calibration, it defaults to the high point of the calibration. This procedure will be followed for all sample analysis. 8.1.5 Initial Calibration Verification (ICV): The quality control standard is the initial calibration verification solution (ICV), which must be prepared in the same acid matrix as the calibration standards. This solution must be an independent standard at approximately half (or less than) of the concentration of the high standard used for instrument calibration. An independent standard is defined as a standard composed of the analytes from a source different from those used in the standards for instrument calibration. 8.1.6 Reporting Limit Verification Standard (RLVS / CRDL): With every Initial Calibration, a standard corresponding to the Pace reporting limit (PRL), or lower, must also be analyzed and meet established acceptance criteria. The RLVS is analyzed prior to any samples being analyzed. It is also analyzed at the end of the analytical sequence when following 6020B quality control samples (LOD sets and DOC sets) or by client request. Additional RLVSs may be analyzed throughout the analytical sequence at the analyst's discretion. These standards are the first calibration point for the analytes of interest. The analysis of this standard demonstrates the instruments ability to report down to the reporting limit with known accuracy. 8.1.7 ICS LDR 1, 2, and 3: These standards are analyzed to establish the linear range with each calibration. The set is essentially all of the major cations in 3 separate standards since combining all of them in one standard would cause problems with the internal standard recoveries due to the total amount of dissolved solids present. It is known that the single element Al and Ca standards contain a background of Sr above the first calibration point at Any printed copy of this SOP and all copies of this SOP outside of Pace are uncontrolled copies.

The control limit for Sr in these 2 standards (LDR 1 & 2) is < RL above the mean background concentration. 8.1.8 Interference Check Solutions (ICSA and ICSAB): The ICSA and ICSAB are prepared to contain known concentrations of interfering elements that will demonstrate the magnitude of interferences and provide an adequate test of any corrections. The ICSA and ICSAB are analyzed prior to any samples. They are also analyzed at the end of the analytical sequence by client request. Chloride in the ICS provides a means to evaluate software corrections for chloride-related interferences such as 35CI 160 on 51V. Iron is used to demonstrate adequate resolution of the spectrometer for the determination of manganese. Molybdenum serves to indicate oxide effects on cadmium isotopes. The other components are present to evaluate the ability of the measurement system to correct for various polyatomic isobaric interferences. The ICS is used to verify that the interference levels are corrected by the data system to within quality control limits. Table D provides a summary of the ICS-A and ICS-AB solution concentrations used. 8.1.9 Continuing Calibration Verification (CCV): This standard is near (or less than)the midpoint of the curve and used to verify that the instrument is still in calibration. This standard is from the same source as the calibration standards. 8.2 Reagents: Please see Table 8.4 for a list of reagents. 8.2.1 All standards, reagents, and spiking solutions are kept at room temperature. Stock standards and reagents can be used until they expire. Refer to the most recent version of ENV-SOP-GBAY-00145 Laboratory Supply Procedures for stock standard and reagent expiration rules. Intermediate and working standards are given a six-month expiration date. However, the expiration date may not extend past the earliest expiration date of any stock standard used to create the solution. The use of any standard or reagent will be terminated if any contamination or problems arise prior to the expiration date. 8.3 Log-in of Standards, reagents, and spike solutions are logged as follows: 8.3.1 Stock standards have a copy of their certificate of analysis logged into the LIMS (Epic Pro).

High solids and complex matrices can and do result in more frequent calibration. 9.1.1 Calibration Curve: Demonstration and documentation of acceptable initial calibration is required before any samples are analyzed and is required periodically throughout sample analysis as dictated by the results of the continuing calibration verification standards. Calibration consists of a calibration blank and four or five non-zero standards (analyte dependent) analyzed after a calibration blank. The ICPMS software creates a curve based on this data which is linear regression using Absolute Standard Deviation weighting inclusive of the calibration blank with a calculated intercept and uses the following equation: Y=a(x)+b. In calculating x (concentration)from y (response)the b (intercept) is subtracted. The b represents the intercept of the regression line. The correlation coefficient must be 4.998. If the correlation coefficient is not within criteria, the issue must be resolved, and the instrument recalibrated with passing criteria prior to analyzing samples. To satisfy 6020B calibration criteria the following must be met. The calculated concentration for the lowest calibration point used must have a recovery of+/-20% (i.e. a relative error of<_20%). The calculated concentration midpoint calibration standard must have a recovery of+/-10% (i.e. a relative error of 510%). The calculated concentration highpoint calibration standard must have a recovery of+/-10% (i.e. a relative error of<_10%)for LDR in 6020B. 9.1.2 Calibration Levels: Please see Table Below for directions on making the calibration standards and the calibration levels used in the calculations.

For full mass range scans, a minimum of six internal standards must be used. Procedures described in this SOP for general applications detail the use of seven internal standards; 6Li, 45Sc-CCT, 45Sc-KED, 72Ge, 89Y, 115ln, 159Tb, and 209Bi.

This is achieved by directly adding the internal standard stock solution (100ppb in 3% HNO3) to all samples, standards, and blanks by on-line addition prior to nebulization using a second channel of the peristaltic pump and a mixing T-connector. The concentration of the internal standard should be sufficiently high that good precision is obtained in the measurement of the isotope used for data correction and to minimize the possibility of correction errors if the internal standard is naturally present in the sample. A final concentration at the nebulizer of approximately 50 ppb will result from the addition of a 100 ppb solution. 9.1.3.3 Due to matrix interferences one or more of the internal standards may not be suitable. It is up to the analyst to recognize and correct the problem by diluting the sample(s) for reanalysis. This procedure may result in some analytes being diluted below the PRL and must be appropriately flagged. 9.1.3.4 During the determination, the software uses the ratio of analyte and internal standard intensities to adjust the final concentration values. Ratios are based on the intensities in the sample vs. the calibration blank intensities. 9.1.3.5 An internal standard without Li must be used if Li is an analyte of interest. If Li is to be used as an internal standard, and Li is an analyte of interest, an isotopically enriched Li standard must be used such that the analyte can be differentiated from the internal standard. (i.e. 6Li enriched internal standard to report 7Li in samples.) 9.1.4 Interference Calculations: Interference equations are used to correct for isobaric elemental and polyatomic interferences. All equations can be adjusted if necessary or added if the analyst determines that any particular correction is insufficient or if an equation is over correcting the data.

The mean value in counts per second (cps)for the calibration blank MUST be > 0 cps (ideally, all replicates should be > 0 cps). The normal operating range in cps is 0- 1 1000cps for the calibration blank and must be inspected by the analyst. 2-The ICSA/AB and the LCS sample are used in the evaluation of this equation. Ca is affected by doubly charged strontium and can vary from day to day plasma conditions. The ICSA&AB will not fully identify doubly charged conditions based on the ratio of Ca to Sr, whereas the LCS sample for waters and soils have sufficiently large Sr concentrations compared to Ca and will assist in identification of adjustment requirements for the Ca interference equation. 3-Zirconium must be less than the previously established linear dynamic range (LDR) of 10,000 pg/L on instrument for proper correction of polyatomic and doubly charged interferences. 9.1.5 Acquisition Mode: Points per Mass: 1 Number Replicates: 3 Dwell Time: 10 ms for all elements except Na, As, Se, Kr; 5 ms for Na, and 50 ms for As, Se, Kr. 9.1.6 Example Peristaltic Pump Program: Uptake time: 20 sec Any printed copy of this SOP and all copies of this SOP outside of Pace are uncontrolled copies.

The analog counting will appear to sit significantly above the pulse baseline in an observed spectra from the scan acquisition and indicates that the cross calibration needs to be performed. Also, an indication of when the Xcal needs to be reset is when the calibration loses its linearity (this will likely occur first with High Resolution Mineral elements like Na and K or high concentration elements like Fe. A deviation can also be observed for the heavy elements TI, Pb, and U).

This is done when the deviation between the pulse and analog counting methods is observed (from spectra or from linearity observations) and the minimum counts per second listed in the tuning section are achievable. Run the Instrument Calibration wizard in PlasmaLab when deviation of the analog spectra is observed. The detector cross calibration is selected by default in the wizard. This will reset the detector-gating plateau such that the analog spectra (dashed line in the spectra) will sit directly on top of the pulse baseline (solid line in the spectra). 9.2.3.4.2 Detector Setup and Cross Calibration. This is done when the minimum counts per second listed in the tune section are not achievable. Thus, the detector dynode value will be adjusted, and a new cross calibration will be performed with the new detector voltage setting. Launch the Instrument Calibration wizard in PlasmaLab and select detector set up. The detector cross calibration will be checked by default, also select the detector set up portion in the wizard. The voltage applied to the detector will be set first to achieve acceptable sensitivity followed by a detector cross calibration with the new detector setting. 9.2.3.4.3 Dead Time Experiment: This experiment must be and is only performed after a detector is replaced. The dead time experiment will identify the delay or "dead time" associated with a particular detector. The dead time is the delay between the pulse measurement and analog measurement when the detector gate is dropped. In the experiment a 1 ppb and 10ppb solution of Uranium is run, and the ratios between 235U and 238U are calculated for both concentrations. The values for the ratios are adjusted such that the ratio values are as close to identical as possible and that value (dead time in nanoseconds) is entered into PlasmaLab software via the Advanced Page. 9.2.3.5 Tune Procedure Summary (Use this order of events, some adjustments may be required after an auto tune). Save each passing configuration with the Mode followed by the Date (e.g. Standard Mode, CCT Mode, and KED Mode 09052020). The tunes for passing performance reports are valid for 36 hours. Introduce the internal standard and aspirate a new rinse blank for 5-10 minutes to eliminate any carry-over into the calibration blank.

A typical sequence will consist of a calibration blank and calibration points 0 through 5, followed by an ICV, ICB, CRDL, ICSA, ICSAB, CCV, CCB and then batch samples and QC. The repeat rules set above will insert a CCV, CCB combo every 10 analyses and at the end of the sequence. 9.2.4.3 Ensure the RLVS / CRDL standard bracket the sample list for analysis by 6020B for LOD and DOC analysis. The bracketing check may be by Client specific criteria and refer to any applicable requirements if there is uncertainty. 9.2.4.4 When the sample list and QC checks have been verified for accuracy, queue the experiment to the Technician Queue. Each experiment will require a unique code (e.g. 0905220A, 0905220B, for 401CM2, and add _3 after the name for 401CM3, etc.). 9.2.4.5 Expected values and limits for ICV, CCV, ICS LDR (1,2,&3), ICS-A, and ICS-AB can be found in Attachment II. 10.0 DATA ANALYSIS AND CALCULATIONS 10.1 The Plasma Lab software performs all calculations necessary to convert raw counts per second data into quantitative concentration results. 10.2 Consideration should be given to the interference equations that are in the method. As a result of changing tune parameters over time, the equations may require adjustment periodically to ensure they are not overcompensating or under compensating for the polyatomic or isobaric interferences. This is especially true of 52Cr and 51V as the CCT-KED tune can vary slightly from day to day operation. This variation (primarily in the add gas for the collision cell) will change the counts per second acquired for CI and CIO ions. This can make the counts per second in the calibration blank for these isotopes artificially high or low (See Section 9.1.4). In the case of Lead, quantitation is based on the sum of isotopes 206, 207, and 208 to compensate for any variation in naturally occurring isotope ratios. This is accomplished through the use of the interference correction equation for lead. Any printed copy of this SOP and all copies of this SOP outside of Pace are uncontrolled copies.

They consist of Method QC, Instrument QC, and Prep/Batch QC. 11.2 Method QC consists of the instrument detection limits, linear ranges, method detection limits, the lower limit quantitation check, and demonstrations of capability. This QC must be completed prior to analyzing any samples. 11.2.1 Instrument Detection limits (IDLs): IDLs in pg/L are estimated as the mean plus the average of the standard deviations of the three runs on three non-consecutive days from the analysis of a reagent blank solution with ten consecutive measurements per day. Each measurement must be performed as though it were a separate analytical sample (i.e., each measurement must be followed by a rinse and/or any other procedure normally performed between the analysis of separate samples). IDLs must be determined quarterly. 11.2.2 Linear Dynamic Ranges (LDR): The LDR for each element is determined by analyzing a standard series ending at a concentration expected to be near the high end of the instruments range. The result must be within ± 10% of the expected concentration, or a lesser concentration tested until acceptable results are obtained. This procedure is done with each new instrument to determine the LDR of a particular model of Instrument and methodology. This is critical to the determination of any doubly charged, polyatomic and memory interferences. Once established, 6020B methodology will be followed. For 6020B the LDR is verified for each calibration. If the ICS solutions for the higher concentration elements does not recover within the 90-110% acceptance range, the high point of the calibration sets the high end of the instrument working range and is the highest reportable concentration for that element. The 6020B criteria is more stringent than 200.8 and will be followed for both methods. 11.2.3 Method Detection Limits (MDLs): Method detection limits, at a minimum, are obtained by multiplying 3.143 by the standard deviation of seven spikes. The spikes went through the digestion procedures and were spiked at a concentration suspected to be within a factor of ten greater than the MDL. The most recent version of the MDL SOP, S-ALL-Q-004, must be followed when determining MDLs. Note: The MDL determined by the MDL study is the theoretical MDL. The MDL used for reporting purposes may be higher than the theoretical MDL. 11.2.4 Lower Limit of Quantitation Check Standard (LLOQ): The LLOQ is a standard at the reporting limit concentration that has gone through all the preparation procedures. For the purposes of 6020B, the acceptance criteria is ± 35% for the LLOQ sample. The Percent RSD for the acquired LLOQ replicates should be <_ 20%. It is analyzed to establish the lower limit of quantitation, verified quarterly using the data from the LOD studies collected throughout the year, and whenever new limits are established. If an element repeatedly does not meet criteria at a certain level, it should be re- evaluated to determine if that level is realistic.

When the intensity of any required internal standard fails to fall between 60 and 125 percent of the intensity of that internal standard in the blank of the calibration, one of the following procedures is followed'. The sample is diluted appropriately and reanalyzed with the addition of appropriate amounts of internal standards. This procedure must be repeated until the required internal standard intensities fall within the prescribed window. If significant deviation cannot be overcome by dilution of the sample in the same analytical run, then recalibration is required. Sudden increases in internal standard recoveries of 10 or more percent may also indicate that dilutions are necessary. The presence of high levels of dissolved solids in samples can result in instrument drift. A sequence with high solids samples will have recoveries drift down. Should the internal standards drift outside of the acceptance range; these samples will need to be re-analyzed at a dilution. If a subsequent batch is clean (samples with low dissolved solids present) the instrument may see an increase in signal and internal standard recovery. Unless the internal standards are actually present in the samples, these can be re-analyzed at the same dilution after a passing recalibration. 16020B allows for the lower limit of the internal standard recovery to be set at 30%. 11.3.2 The ICSA, ICSAB, and ICS LDR solutions are used to verify the magnitude of elemental and molecular-ion isobaric interferences and the adequacy of any corrections. They are analyzed after the CRDL, prior to the analysis of any samples. For 200.8, additional ICSA and ICSABs are not analyzed, as sequences do not reach 12 or more hours in duration. By client request, the ICSA and ICSAB will be analyzed at the end of the analytical sequence. The analyst should be aware that precipitation from solution AB may occur with some elements, specifically silver. The control limits for the elements in the ICSA and ICSAB solutions is 80 to 120% for 200.8 and those elements not being used for linear range purposes. For 6020B the recovery of the elements with concentrations to establish the linear range is 90-110% (specifically for Ti and Mo). Elements that are not spiked in the ICSA, must have a measurement lower than the LOQ. If an element of interest does not meet these limits, then the problem must be corrected, the instrument recalibrated, and the run reanalyzed. 11.3.3 The ICV is analyzed to check the accuracy of the curve. It must be evaluated after each calibration and before any samples are analyzed. The ICV should be at or near (or lower than) the midpoint of the calibration curve, derived from a source independent of the calibration standards, and must quantitate within ± 10% of the expected value. If these limits are not met for an element of interest, the problem must be corrected, the instrument recalibrated, and the run reanalyzed. If the ICV fails high and the samples are non-detects, then they may be reported. 11.3.4 Reporting Limit Verification Standard (RLVS / CRDL): With every Initial Calibration, a standard corresponding to the Pace reporting limit (PRL) or lower than the derived LLOQ Any printed copy of this SOP and all copies of this SOP outside of Pace are uncontrolled copies.

The RLVS is analyzed prior to any samples being analyzed. By client request it will also be analyzed at the end of the analytical sequence. Additional RLVSs may be analyzed throughout the analytical sequence at the analyst's discretion. The limits for the RLVS are ± 30% of the true concentration. These standards are the first calibration standard for the analytes of interest. The analysis of this standard demonstrates the instruments ability to quantify down to the reporting limit with known accuracy. If an element fails the CRDL, but the CCV passes and the samples are greater than the CCV concentration or if the samples are <LOD/ ND, then the sample data may be reported with the filing of a non-conformance report with the data. Results >LOD but<CCV must be re-analyzed under passing criteria. 11.3.5 The CCV is analyzed to check for calibration drift. The CCV is run prior to any samples, after every 10 samples and again at the end of samples. It must quantitate within 10% of the expected value. Any sample analyzed under out-of-control calibration must be reanalyzed, following the successful re-calibration of the instrument. If the CCV fails high and the samples are non-detects, then they may be reported. All others must be re- analyzed under passing criteria. 11.3.6 The ICB is analyzed to check the accuracy of the curve. The CCBs are analyzed to check for calibration drift and memory from high concentration samples. In the absence of Project specificreportinglimits, 1/2the results of the calibration blanks must be less than the LLOQ (<1/2 the concentration in Cal 1). For the ICB result must be less than one half the reporting limit (for ease in identifying an issue, reference the first non-zero standard). The ICB is run after the ICV and the CCBs are run after the CCVs. If the CCB fails high for an analyte and the samples are non-detects or are greater than 10x the blank value, then they may be reported. All others must be re-analyzed under passing criteria. 11.4 A batch will consist of 20 or fewer samples. Batch Quality Control will include a Method Blank (MB), Chicken Blank (CB) (Biota only), Laboratory Control Spike (LCS), Matrix Spike (MS), Matrix Spike Duplicate (MSD), Post Digestion Spike (PDS), and a Serial Dilution (SD). It may also include a Laboratory Control Spike Duplicate (LCSD) and/or Standard Reference Material (SRM). 11.4.1 The Method Blank is used to verify that interferences caused by contaminants in the solvents, reagents, glassware, etc. are known and minimized. The method blank is processed through all clean-ups, etc., which were performed on the samples in the batch. For a method blank to be acceptable, in the absence of project specific criteria, the concentration shall not be higher than the highest of the following: The reporting limit, or ten percent of the regulatory limit of concern for that analyte, or ten percent of the measured concentration in a particular sample of interest. Each sample in the batch is assessed against the above criteria to determine if the sample results are acceptable. Any sample associated with an unacceptable blank is either flagged, re-prepped for analysis, or if re- prepping is not an alternative, the results are reported with the appropriate data qualifying codes. 11.4.2 The Chicken Blank (CB) must be prepared with every biota batch, and is processed through all clean-ups, etc., which were performed on the samples. It consists of a control matrix (ground chicken) to verify the interferences in the biological tissue is known and minimized. The CB will contain detectable amounts of elements such as K, Ca, Na, Mg, and P etc., and is used to ensure acceptable performance of the laboratory control spike.

Laboratory Control Samples are analyzed at a minimum of 1 per batch of 20 or fewer samples or preparation method. Results of the LCS are expressed in terms of percent recovery and are used to determine batch acceptance. Acceptance limits 6020B are 80 to 120% of the expected concentration. Acceptance limits for 200.8 are 85 to 115% of the expected concentration. If these limits are not met with the instrument in control, then the entire batch will be re-digested and re-analyzed. 11.4.4 An LCS Duplicate may be analyzed to evaluate laboratory precision. The LCSD must also meet the criteria for the LCS. The Relative Percent Difference (RPD)will be calculated between the LCS and LCSD. The RPD is calculated as outlined below: RPD = I Di - D2 [ x 100 (Di, + D2,)/2 Where: RPD = relative percent difference. Di =first sample value. D2 = second sample value (duplicate) The control limit for RPD is 20% or is based on laboratory generated data and not to exceed 20%. If outside this limit, all associated results are given a R1 data qualifier. Data generated with LCS samples that fall outside the established acceptance criteria are judged to be out-of-control. These data are considered suspect and the corresponding samples are reanalyzed or reported with qualifiers. For the biota matrix, any detections greater than the MDL must be subtracted from the LCS/LCSD on-instrument value before calculating the recovery limits. NOTE: In the event where adequate sample is not supplied by the client to perform a Matrix Spike/ Matrix Spike Duplicate, the LCS and duplicate can lend insight on the precision of the analysis. 11.4.5 Matrix spikes (MS and MSD) are performed to evaluate the effect of the sample matrix upon analytical methodology. A separate aliquot of sample is spiked with the analyte of interest and analyzed with the sample. For 6020B an MS and MSD are performed at a minimum frequency of 5% per batch. One pair in 20 samples, per matrix type, per sample preparation method and are performed more frequently where regulations require. For 200.8, an MS/MSD pair, are performed at a 10% frequency per batch. Matrix spike recoveries are evaluated against in-house control limits. The recovery must not exceed 75 to 125% of the expected recovery. If outside this recovery, the parent is flagged with an appropriate data qualifier. If the recovery of an analyte is outside this range but the spike level in not at least 25% the background concentration in the parent sample, the data is flagged with an appropriate data qualifier. The RPD between the MS and MSD must be less than or equal to 20%. If outside this limit, the parent is given an appropriate data qualifier. The parent sample for the MS/MSD is chosen at random unless specified by a client. Poor performance in a matrix spike generally indicates a problem with the sample composition, and not the laboratory analysis, and results are used to assist in data Any printed copy of this SOP and all copies of this SOP outside of Pace are uncontrolled copies.

A matrix effect is indicated if the LCS data are within acceptance criteria, but the matrix spike data exceed the acceptance criteria. Prior to calculating recovery, the parent sample concentration (results <Reporting MDL = 0) is subtracted from the spike aliquot concentrations. 11.4.6 The Post Digestion Spike (PDS) is run to verify matrix interferences. A spike is added to a portion of a prepared sample, or its dilution and must be recovered to within 80 to 120 percent of the known value. If the spike is not recovered within the specified limits with the instrument in control, then the sample has a confirmed matrix effect. Dilute the parent and re-spike the diluted sample until the PDS recovers within acceptance criteria. 11.4.7 The Serial Dilution (SD) is run to check for matrix interferences. If the analyte concentration is within the linear dynamic range (LDR) of the instrument and sufficiently high (minimally, a factor of at least 10 times greater than the lower limit of quantitation for the diluted sample, 50 times the RLVS standard for the parent sample, or by project/client specific criteria) an analysis of a fivefold (1+4) dilution must agree within ± 10% of the original determination for 200.8. For the analysis of 6020B the limit is 25 times the RLVS standard with the fivefold dilution agreement ± 20%. If these limits are not met, then an interference effect must be suspected, and the data qualified with an SD data qualifier. If the analytes of interest are greater than the LDR in the parent sample, the sample can be diluted, and an SDL done from the dilution. Client specific requirements may require different reference concentrations and limits. 11.4.8 The type of SRM is typically prepped and analyzed upon client request. It is a sample of known concentration chosen to resemble the matrix being analyzed. Unless an alternative is provided and specified by the client, the default SRM used for all Biota batches is TORT- 3 (Lobster Hepatopancreas) as it contains 15 commonly requested elements. 11.5 Data Assessment and Acceptance Criteria for QC Measures Analytical Frequency Method b Quality Control Measure 41 Acceptance Criteria Method Blank One per batch, not to exceed 20samples. < LOD <LOQ Laboratory One LCS per batch, not to exceed 20samples. 6020B: ±20% recovery of the true value.

Refer to Pace ENV corporate SOP ENV-SOP-CORQ-0011 Method Validation and Instrument Verification and to the laboratory's SOP ENV-SOP-GBAY-0106 Determination of LOD and LOQ (most recent revision or replacement)for these procedures. 11.6.1.2 The LOD and LOQ are always adjusted to account for actual amounts used and for dilution. 11.6.1.3 Current LOD and LOQ can be found in the Laboratory Information Management System (LIMS)— EpicPro and is subject to change. 11.6.1.4 Level of Detection (LOD): The LOD is determined by the 40CFR Part 136B MDL study. Once the 40CFR Part 136B MDL is determined it may be elevated if deemed unrealistic as demonstrated using method blank evaluations. 11.6.2 Periodic performance evaluation (PE) samples are analyzed per ENV-SOP- GBAY-0107, PE/PT Program (current revision or replacement), to demonstrate continuing competence. All results are stored in the QA office. At a minimum, these are performed twice a year for the aqueous and soil matrices 11.6.3 A linear dynamic range study must be conducted at least once. The study is conducted for each element by analyzing increasing concentrations (at least 3 levels) until the results generated exceed ±10% difference from the true value, or another reason the data becomes of unacceptable quality (e.g. Internal Standard Recovery failure or excessive memory effect). The highest concentration within the 10% criteria is the maximum of the linear range for that element.

For the analysis of samples, the highest standard used in the same calibration event must be used for the linear range within that analysis set. If the ICS LDR standards at levels higher than the upper calibrations standard do not meet± 10% the true value of the standard, then the linear range becomes the same concentration as the highest calibration standard provided the readback after the linear regression is 90-100% the expected value. All samples will be diluted and reanalyzed that are over the linear calibration range. 11.7 Analyst Qualifications and Training Employees that perform any step of this procedure must have a completed Read and Acknowledgment Statement for this version of the SOP in their training record. In addition, prior to unsupervised (independent) work on any client sample, analysts that prepare or analyze samples must have successful initial demonstration of capability (IDOC) and must successfully demonstrate on-going proficiency on an annual basis. Successful means the initial and on-going DOC met criteria, documentation of the DOC is complete, and the DOC record is in the employee's training file. Refer to laboratory SOP ENV-SOP-GBAY-0094 Orientation and Training Procedures (most recent revision or replacement)for more information. 12.0 DATA REVIEW AND CORRECTIVE ACTION 12.1 Data Review Pace's data review process includes a series of checks performed at different stages of the analytical process by different people to ensure that SOPs were followed, the analytical record is complete and properly documented, proper corrective actions were taken for QC failure and other nonconformance(s), and that test results are reported with proper qualification. The review steps and checks that occur as employee's complete tasks and review their own work is called primary review. An experienced peer or supervisor also reviews all data and results. Secondary review is performed to verify SOPs were followed, that calibration, instrument performance, and QC criteria were met and/or proper corrective actions were taken, qualitative ID and quantitative measurement is accurate, all manual integrations are justified and documented in accordance with the Pace ENV's SOP for manual integration, calculations are correct, the analytical record is complete and traceable, and that results are properly qualified. Reporting performs a third-level review, called a completeness check, or project management staff to verify the data report is not missing information and project specifications were met. Refer to laboratory SOP ENV-SOP-GBAY-0120 Data Review and Final Report Processes (most recent revision or replacement) for specific instructions and requirements for each step of the data review process. Draw a single-line strikethrough for any unacceptable or changed data, then DATE and INITIAL and provide a written explanation of the reason for the change. Any printed copy of this SOP and all copies of this SOP outside of Pace are uncontrolled copies. Uncontrolled copies are not tracked or replaced when new versions are released or the SOP is made obsolete. Users of the SOP should verify the copy in possession is the current version of the SOP before use.

Any discrepancies and issues occurring with each batch should be included on the cover sheet to be incorporated into a narrative. To assist the primary and secondary reviewer of the data, a spreadsheet (ENV-FRM-GBAY- 0428) was created to copy and paste the calibration curve and initial QC samples into from the LIMS Link generated bench sheet. This spreadsheet will automatically flag any non-compliant quality control samples and QC checks. 12.2 Corrective Action Corrective action is expected any time QC or sample results are not within acceptance criteria. If corrective action is not taken or was not successful, the decision/outcome must be documented in the analytical record. The primary analyst has primary responsibility for taking corrective action when QA/QC criteria are not met. Secondary data reviewers must verify that appropriate action was taken and/or that results reported with QC failure are properly qualified. Corrective action is also required when carryover is suspected and when results are over range. Samples analyzed after a high concentration sample must be checked for carryover and reanalyzed if carryover is suspected. Carryover is usually indicated by low concentration detects of the analyte in successive samples analyzed after the high concentration sample. Sample results at concentrations above the upper limit of quantitation must be diluted and reanalyzed. The result in the diluted samples should be within the upper half of the calibration range. Results less than the mid-range of the calibration indicate the sample was over diluted and analysis should be repeated with a lower level of dilution. If dilution is not performed, any result reported above the upper range is considered a qualitative measurement and must be qualified as an estimated value. 12.2.1 DATA ASSESSMENT/CORRECTIVE ACTION Data Assessment Measure If these conditions are not achieved MB ! 1 LCS/LCSD ! 2 MS/MSD ! 3 PS ! 4 SD ! 5 DUP ! 6 SRM ! 7 Initial Calibration ! 8 ICV ! 9 ICB ! 10 ICSA ! 11 ICSAB ! 12 CRDL ! 13 CCV ! 14 CCB ! 15 Any printed copy of this SOP and all copies of this SOP outside of Pace are uncontrolled copies.

If not<LOQ,verify by second analysis. If second analysis confirms contamination for target analyte at or greater than the LOQ, re-digest sample batch and batch QC provided sufficient sample volume remains. If insufficient sample volume remains, consult with project manager and client on how to proceed. For MB detections greater than or equal to the LOD, but less than the LOQ; qualify applicable sample results. For negative measurements more negative than the LOD, applicable data is given the following data qualifier: "Analyte was measured in the associated method blank at a concentration of- #.#units." *For positive MB failures, samples that are non-detection need not be qualified. In addition,samples that are greater than 10 times the MB detection, need not be qualified. * For negative MB failures samples that are greater than 10 times the absolute value of the negative MB measurement, need not be qualified. 2. Verify failure by second analysis. If second analysis confirms LCS(LCSD)failure, re-digest sample batch and batch QC provided sufficient sample volume remains. If insufficient sample volume remains, consult with project manager and client on how to proceed. 3. If the parent, MS, or MSD is greater than the reportable linear dynamic range, dilute and reanalyze the parent, MS, and MSD. If the concentration of the spike is less than 25%of the concentration of the parent,the MS and MSD recoveries are not evaluated. Any failures resulting from this are qualified appropriately with a P6 qualifier. If the concentration of the spike is greater than 25%of the concentration of the parent, appropriately qualify(MO)the parent sample if either the MS and/or MSD fail accuracy. If the MS and MSD fail precision control limits flag the parent with the appropriate precision data qualifier(R1). 4. If the spike is not recovered within the specified limits with the instrument in control, dilute the parent and re-spike the diluted sample until the PS recovers within acceptance criteria. 5. If these limits are not met(as listed in Table 11.5),then an interference effect must be suspected, and the data qualified with an appropriate data qualifier. If the analytes of interest are greater than the LDR in the parent sample,the sample can be diluted, and an SDL done from the dilution. 6. If the DUP fails precision control limits flag the parent with the appropriate precision data qualifier 7. For Biota analysis only. Outside of client specific criteria,the SRM is digested and analyzed only to demonstrate analyte recovery in a standard reference material. When the recovery is outside the lab generated statistical limits,the element that failed recovery will be flagged in the samples for the element that failed.Client specific action may also exist. 8. Correct the issue and recalibrate. 9. Verify failure by second analysis. If second analysis confirms ICV failure, correct the issue and recalibrate the instrument. No data may be reported unless there is a passing ICV for that target element. If verification passes criteria,then proceed with the analytical sequence. 10. Verify failure by second analysis when possible. If second analysis confirms ICB failure, correct the issue and recalibrate the instrument. No data may be reported unless there is a passing ICB for that target element. 11. Verify failure by second analysis. If second analysis confirms ICSA failure,the system is out of control. Correct the issue and recalibrate the instrument. No data may be reported unless there is a passing ICSA for that target element. 12. Verify failure by second analysis. If second analysis confirms ICSAB failure,the system is out of control. Correct the issue and recalibrate the instrument. No data may be reported unless there is a passing ICSAB for that target element. 13. Verify failure by second analysis when possible. If second analysis confirms CRDL failure,the system is out of control. Correct the issue and recalibrate the instrument. No data may be reported unless there is a passing CRDL for that target element.

Verify failure by second analysis. If second analysis confirms CCV failure,correct the issue and recalibrate the instrument. On unattended sequence, CCVs may fail and then pass later in the sequence, but no data may be reported unless bracketed by passing CCVs for that target element. 15. Verify failure by second analysis when possible. If second analysis confirms CCB failure, correct the issue and recalibrate the instrument. On unattended sequence, CCBs may fail and then pass later in the sequence, but no data may be reported unless bracketed by passing CCBs. Exceptions;if the failure is biased high and the sample is a non-detection, or the sample concentration is greater than 10 times the detection in the CCB for that target element. High concentration samples are the likely cause of a CCB failure. The memory in the sample introduction system was not high enough to cause a CCV failure, but enough to cause a CCB to fail high. 13.0 POLLUTION PREVENTION AND WASTE MANAGEMENT Pace proactively seeks ways to minimize waste generated during our work processes. Some examples of pollution prevention include but are not limited to: reduced solvent extraction, solvent capture, use of reusable cycletainers for solvent management, and real-time purchasing. The EPA requires that laboratory waste management practice to be conducted consistent with all applicable federal and state laws and regulations. Excess reagents, samples and method process wastes must be characterized and disposed of in an acceptable manner in accordance with Pace's Chemical Hygiene Plan / Safety Manual. For further information on waste management, consult ENV-SOP-GBAY-0125 Waste Handling and Management(most recent revision or replacement). 14.0 MODIFICATIONS A modification is a change to a reference test method made by the laboratory. For example, changes in stoichiometry, technology, quantitation ions, reagent or solvent volumes, reducing digestion or extraction times, instrument runtimes, etc., are all examples of modifications. Refer to Pace ENV corporate SOP ENV-SOP-CORQ-0011 Method Validation and Instrument Verification for the conditions under which the procedures in test method SOPs may be modified and for the procedure and document requirements. 14.1 When there is insufficient volume provided by the client for the method specified matrix spike/matrix spike duplicate (MS/MSD), a laboratory control spike duplicate will be analyzed to demonstrate precision criteria. Laboratory batches will be qualified with the appropriate "M5" data qualifier. When performing this analysis on paint chip samples, a MS/MSD will not be completed on the samples due to high levels of elements present in the native sample. 15.0 RESPONSIBILITIES Pace ENV employees that perform any part this procedure in their work activities must have a signed Read and Acknowledgement Statement in their training file for this version of the SOP.

For the most up to date LOQ, refer to the LIMS or contact the laboratory. LOQ are established in accordance with Pace policy and SOPs for method validation and for the determination of detection limits (DL) and quantitation limits (LOQ). DL and LOQ are routinely verified and updated when needed. The reporting limit (RL) is the value to which analytes are reported as detected or not detected in the final report. When the RL is less than the lower limit of quantitation (LLOQ), all detects and non-detects at the RL are qualitative. The LLOQ is the lowest point of the calibration curve used for each target analyte. DL, LOQ, and RL are always adjusted to account for actual amounts used and for dilution. 1.2 Applicable Matrices- EPA 245.6 applies biological tissue samples. 1.3 Personnel: The policies and procedures contained in this SOP are applicable to all personnel involved in the analytical method or non-analytical process. 2.0 SUMMARY OF METHOD 2.1 Cold vapor atomic absorption utilizes the volatile property of elemental mercury at the 253.7 nm wavelength. To release mercury from organic complexes, the sample is digested with oxidizing reagents and acids in a hot block digester at 58°C, followed by overnight oxidation with potassium permanganate and potassium per-sulfate at room temperature. 2.2 After digestion, the oxidizing reagents are neutralized by adding hydroxylamine hydrochloride. The Flow Injection Analysis System sweeps the volatile elemental mercury out of the sample and into the cell of an atomic absorption spectrophotometer. The absorbance signal is proportional to the amount of mercury in the sample. 2.3 Results are reported in parts per million (mg/kg). 3.0 INTERFERENCES 3.1 Biota samples can contain diverse matrix types, each of which may present analytical challenges. Spiked samples and Laboratory Control Samples are important for determining digestion efficiency. Any printed copy of this SOP and all copies of this SOP outside of Pace are uncontrolled copies. Uncontrolled copies are not tracked or replaced when new versions are released, or the SOP is made obsolete. Users of the SOP should verify the copy in possession is the current version of the SOP before use. ..tnc aceAnaIicaI® TEST METHOD STANDARD OPERATING PROCEDURE TITLE: Mercury Analysis of Biological Samples by CVAAS CETAC M-7500 TEST METHOD EPA 245.6 ISSUER: Pace ENV—Green Bay—GBAY COPYRIGHT©2020 Pace Analytical Services, LLC 3.2 During the oxidation step, chlorides are converted to free chlorine, which also absorbs radiation at 253.7 nm. Care must therefore be taken to ensure that free chlorine is absent before the Mercury is reduced and swept into the cell. This may be accomplished by using an excess of hydroxylamine hydrochloride reagent. 3.3 Certain volatile organic materials that absorb at this wavelength may also interfere. A preliminary run without reagents may be used to determine if this type of interference is present. 4.0 DEFINITIONS Refer to the Laboratory Quality Manual for a glossary of common lab terms and definitions. 4.1 Biota Control Blank (Matrix Blank): A sample of a matrix that is used for the control spike. The biota control blank will either be catfish, tilapia, chicken, or other tissue whichever is available at the time of analysis. The biota control blank should be "farm-raised" to minimize background mercury levels. The concentration in the biota control blank will be subtracted from the concentration of the laboratory control spike when the biota control blank concentration is greater than/equal to the MDL. This is done because the biota control blank is known to have some contamination. This SOP will reference biota control blank for ease. Note: For plant material analysis, alfalfa can be used as the biota control blank matrix. 4.2 Standardized Reference Material (SRM): A certified reference material produced by the U.S. National Institute of Standards and Technology or other equivalent organization and characterized for absolute content, independent of analytical method. A SRM is analyzed with each analytical batch of biota samples. 5.0 HEALTH AND SAFETY The toxicity or carcinogenicity of each chemical material used in the laboratory has not been fully established. Each chemical should be regarded as a potential health hazard and exposure to these compounds should be as low as reasonably achievable. The laboratory maintains documentation of hazard assessments and OSHA regulations regarding the safe handling of the chemicals specified in each method. Safety data sheets for all hazardous chemicals are available to all personnel. Employees must abide by the health, safety and environmental (HSE) policies and procedures specified in this SOP and in the Pace Chemical Hygiene /Safety Manual. Personal protective equipment (PPE) such as safety glasses, gloves, and a laboratory coat must be worn in designated areas and while handling samples and chemical materials to protect against physical contact with samples that contain potentially hazardous chemicals and exposure to chemical materials used in the procedure. Concentrated corrosives present additional hazards and are damaging to skin and mucus membranes. Use these acids in a fume hood whenever possible with additional PPE designed for handing these materials. If eye or skin contact occurs, flush with large volumes of water. When working with acids, always add acid to water to prevent violent reactions. Any processes that emit large volumes of solvents (evaporation/concentration processes) must be in a hood or apparatus that prevents employee exposure. Any printed copy of this SOP and all copies of this SOP outside of Pace are uncontrolled copies. Uncontrolled copies are not tracked or replaced when new versions are released, or the SOP is made obsolete. Users of the SOP should verify the copy in possession is the current version of the SOP before use.

The samples must undergo a special procedure to destroy any Hantavirus, which may be present. Refer to the most recent version of SOP ENV-SOP-GBAY-0130 Small Rodent Handling and Homogenization for details. Contact your supervisor or local HSE coordinator with questions or concerns regarding safety protocol or safe handling procedures for this procedure. 6.0 SAMPLE COLLECTION, PRESERVATION, HOLDING TIME, AND STORAGE Samples should be collected in accordance with a sampling plan and procedures appropriate to achieve the regulatory, scientific, and data quality objectives for the project. The laboratory does not perform sample collection or field measurements for this test method. To assure sample collection and field checks and treatment are performed in accordance with applicable regulations Pace project managers will inform the client of these requirements at the time of request for analytical services when the request for testing is received prior to sample collection. If samples were already collected, the laboratory will record any nonconformance to these requirements in the laboratory's sample receipt record when sufficient information about sample collection is provided with the samples. The laboratory will provide containers for the collection of samples upon client request for analytical services. Bottle kits are prepared in accordance with laboratory SOP ENV-SOP-GBAY-0007 Bottle Preparation (current revision or replacement). 6.1 Where applicable, the bottle ware is demonstrated to be fee of target analytes. When bottle ware not originating from the lab is used, the data may be qualified with either one or both of the following data qualifiers: 6.1.1 Sample field preservation does not meet EPA or method recommendations for this analysis. 6.1.2 Sample container did not meet EPA or method requirements.

At a minimum these included ICV, ICB, CRDL, CCV(s), and CCB(s). See section 11 for more details on calibration verification QC. 9.5.7 See Attachment I: QC Summary and laboratory SOP: ENV-SOP-GBAY-0138, Calibration Procedures (most recent revision or replacement)for additional guidance. 9.6 Biological Tissue Sample Digestion (EPA 245.6): 9.6.1 50 mL digestion vials are used for Biota samples. 9.6.2 Prior to analysis the samples and calibration curve must be digested. 9.6.3 Turn on the hot block and set the temperature to maintain a sample temperature of 58±3°C. Before placing samples in the hot block to digest, use a temperature blank to verify that the block temperature is correct and adjust as required. Record the temperature in the electronic prep log. Verify that the hood is functioning. 9.6.4 Add 2.5 mL of Nano-Pure water and add the appropriate amounts (as shown in Section 8.3) of Hg Calibration Intermediate and Hg ICV Intermediate to digestion vials for the curve, ICV, CCV, ICB, and CCB. Additional blanks (and standards) may be prepared to be used as continuing calibration blanks and calibration check standards and to be used as diluent in cases where the sample concentration exceeds the high point of the calibration curve or matrix interferences are observed. 9.6.5 Prepare one Method Blank. For biota analysis, leave the Method Blank empty. A Biota Control Blank is also prepared by weighing 0.6 g of homogenized biota control blank tissue (chicken) into a digestion vial. 9.6.6 Prepare the LCS for biota samples by weighing 0.6 g of homogenized biota control blank 1 into the digestion vial. Add 2.5 mL of Hg ICV Intermediate (100 pg/L CVAA Hg Spk) the vial. Only prep a Laboratory Control Spike Duplicate (LCSD) if requested by client or there is not enough sample to run a MS/MSD. Prepare the LCSD in the same fashion as the LCS. 9.6.7 For biota samples, weigh approximately 0.05 g of Standard Reference Material into a labeled digestion vial (DORM-4 or equivalent). 9.6.8 Weigh 0.6 g of homogenized sample into a labeled digestion vial. Record the weight to the nearest 0.01 g in the digestion prep log. Try to minimize any thawing of the sample during the weighing process to prevent fluid migration within the tissue. 9.6.9 To prepare a Matrix Spike and Matrix Spike Duplicate, a sample with sufficient volume is chosen at random. Weigh 2 additional 0.6g aliquots into digestion vials. Add 2.5 mL of Hg ICV Intermediate (100 pg/L CVAA Hg Spk)to each vial. 9.6.10 To each digestion vial add 2.0 mL of concentrated sulfuric acid and 0.5mL of concentrated nitric acid and cap loosely.

Samples may react violently if added too quickly. 9.6.14 To each sample, including QC, add 4 mL of potassium persulfate solution, cap loosely, and allow the samples to sit overnight at room temperature. 9.6.15 To each sample, including QC, add 3 mL of hydroxylamine solution to decolorize it and let sit for about two hours (capped)to allow gases to diffuse out of solution. 9.6.16 Bring to a final volume of 50 mL with water. 9.6.17 All samples and QC need to be diluted by a dilution factor of 5. Add 2.0 mL of sample to a digestion vessel. Dilute the sample by adding 8.0 mL of blank water that has been digested by the EPA 245.6 method. 9.7 Dry Ice Blank and Blender Blank Preparation: 9.7.1 Dry Ice Blank-Add 50 mL of DI water and 1.0 mL of nitric acid to Dry Ice Blank jar sent by sampler. 9.7.2 Blender Blank — Rinse blender with 50 mL of DI water acidified with 1 mL of nitric acid. Collect in sample container and label as Blender Blank. 9.7.3 Close each sample jar, shake well, and let stand for at least 30 minutes. 9.7.4 Pipette a 25 mL aliquot of the prepared sample into a sample digestion vessel. This procedure will allow enough sample digestate for one re-analysis, if necessary. 9.7.5 Digest the dry ice blank and blender blank. 9.7.6 See Section 10 for calculation of results for dry ice blanks and blender blanks. 9.8 Dilutions: All reported results must be within the range of the calibration curve. Dilute when results are greater than the high standard in the curve. Dilutions on sample extracts must be prepared in a volumetric fashion. Sample aliquots should be taken with a calibrated pipette and brought to an appropriate final volume. In the event a dilution is made to bring a target analyte into calibration range, the analyst should make a dilution such that the target analyte is roughly the equivalent of the mid calibration point whenever possible. 9.9 CETAC M-7500 Basic System Operation (Analytical): This portion of the SOP is designed to allow the user to set up and run a method, print a sample report, then shut down using the more basic software functions.

The filter blank is evaluated and qualified the same as a method blank. 11.3.1.1 Frequency: A MB must be analyzed with each batch of samples or every 20 samples, whichever is more frequent. 11.3.1.2 Acceptance Criteria: The MB is evaluated for both positive and negative bias and must have an absolute value less than the LOQ. For samples reporting down to the LOD, the MB measurements are evaluated to the LOD. In these cases, qualify applicable samples for MB measurements from >LOD to <LOQ. 11.3.1.3 Corrective Action: If the MB is greater than the LOQ, perform the following: 11.3.1.3.1 Check for errors in calculations. If an error or problem is found and can be corrected by amending the calculations and the result falls within the limits, accept the data and report without a qualifier flag. 11.3.1.3.2 If there is sufficient sample available and hold time remaining, re- prepare the MB and all associated. If the MB is less than the LOQ in this analysis, accept the second set of data. If the MB is still outside the RL after re-analysis, contact the PM to determine the resolution. If the client does not require additional work, report the data, applying an appropriate flag to the samples associated with the non-compliant MB. 11.3.1.3.3 If sufficient sample volume is not available, report the sample data with a qualifier flag on each of the samples associated with the non- compliant MB. Contact the project manager regarding the occurrence. Any printed copy of this SOP and all copies of this SOP outside of Pace are uncontrolled copies.

Application may be extended to higher levels by selection of a smaller sample size or by calibration of the analytical system across a higher range. Since the calibration used only extends to 10 pg/L, the reportable linear range will not exceed 10 pg/L. 11.6.1.3 Periodic performance evaluation (PE) samples Periodic performance evaluation (PE) samples are analyzed per ENV-SOP- GBAY-0107, PE/PT Program (most recent revision or replacement), to demonstrate continuing competence. All results are stored in the QA office. 1 11.6.2 Analyst Qualifications and Training Employees that perform any step of this procedure must have a completed Read and Acknowledgment Statement for this version of the SOP in their training record. In addition, prior to unsupervised (independent) work on any client sample, analysts that prepare or analyze samples must have successful initial demonstration of capability (IDOC) and must successfully demonstrate on-going proficiency on an annual basis. Successful means the initial and on-going DOC met criteria, documentation of the DOC is complete, and the DOC record is in the employee's training file. Refer to laboratory SOP ENV-SOP-GBAY-0094 Employee Orientation and Training Procedures (current revision or replacement)for more information. 12.0 DATA REVIEW AND CORRECTIVE ACTION 12.1 Data Review Pace's data review process includes a series of checks performed at different stages of the analytical process by different people to ensure that SOPs were followed, the analytical record is complete and properly documented, proper corrective actions were taken for QC failure and other nonconformance(s), and that test results are reported with proper qualification. The review steps and checks that occur as employees complete tasks and review their own work are called primary review. All data and results are also reviewed by an experienced peer or supervisor. Secondary review is performed to verify SOPs were followed, that calibration, instrument performance, and QC criteria were met and/or proper corrective actions were taken, qualitative ID and quantitative measurement is accurate, all manual integrations are justified and documented in accordance with the Pace ENV's SOP for manual integration, calculations are correct, the analytical record is complete and traceable, and that results are properly qualified. A third-level review, called a completeness check, is performed by reporting or project management staff to verify the data report is not missing information and project specifications were met. Draw a single-line strikethrough for any unacceptable or changed data, then DATE and INITIAL and provide a written explanation of the reason for the change. Any discrepancies and issues occurring with each batch should be included on the cover sheet to be incorporated into a narrative. Any printed copy of this SOP and all copies of this SOP outside of Pace are uncontrolled copies. Uncontrolled copies are not tracked or replaced when new versions are released, or the SOP is made obsolete.

If corrective action is not taken or was not successful, the decision/outcome must be documented in the analytical record. The primary analyst has primary responsibility for taking corrective action when QA/QC criteria are not met. Secondary data reviewers must verify that appropriate action was taken and/or that results reported with QC failure are properly qualified. Corrective action is also required when carryover is suspected and when results are over range. Samples analyzed after a high concentration sample must be checked for carryover and reanalyzed if carryover is suspected. Carryover is usually indicated by low concentration detects of the analyte in successive samples analyzed after the high concentration sample. Sample results at concentrations above the upper limit of quantitation must be diluted and reanalyzed. The result in the diluted samples should be within the upper half of the calibration range. Results less than the mid-range of the calibration indicate the sample was over diluted and analysis should be repeated with a lower level of dilution. If dilution is not performed, any result reported above the upper range is considered a qualitative measurement and must be qualified as an estimated value. 13.0 POLLUTION PREVENTION AND WASTE MANAGEMENT Pace proactively seeks ways to minimize waste generated during our work processes. Some examples of pollution prevention include but are not limited to: reduced solvent extraction, solvent capture, use of reusable cycletainers for solvent management, and real-time purchasing. Regulated soil samples are to be handled in accordance with Pace SOP: ENV-SOP-GBAY-0121, Regulated Soil Handling (current revision or replacement). The EPA requires that laboratory waste management practice to be conducted consistent with all applicable federal and state laws and regulations. Excess reagents, samples and method process wastes must be characterized and disposed of in an acceptable manner in accordance with Pace's Chemical Hygiene Plan/Safety Manual. 14.0 MODIFICATIONS A modification is a change to a reference test method made by the laboratory. For example, changes in stoichiometry, technology, quantitation ions, reagent or solvent volumes, reducing digestion or extraction times, instrument runtimes, etc. are all examples of modifications. Refer to Pace ENV corporate SOP ENV-SOP-CORQ-0011 Method Validation and Instrument Verification(current revision or replacement)for the conditions under which the procedures in test method SOPs may be modified and for the procedure and document requirements. EPA method 245.6 Rev.2.3 1991; throughout the document equipment and supplies are mentioned that have had advances in technology. This has resulted in differences in descriptions (11.2 circulating pump) and procedures (11.6.1 Placing the aspirator inside the BOD bottle)from the method.

The lab uses a 10 % SnCl2 solution made up with a final acid concentration of 7% HCI. This is based on Section 4.1.2 of Quicktrace M-7500 Automated Mercury Analyzer. According to Method 200.3, section 8; Samples should be placed in plastic bag, sealed, and placed on ice or refrigerated at 4 degrees Celsius. The lab practice is to have thermal preservation at 5_6°C. The lab bases this on 40CFR Part 136, page 29808, footnote 18. While Biota is not listed as a matrix, this is consistent with temperature references of EPA methods at 4 degrees Celsius. According to Method 200.3, section 8; Dissection should be performed within 24 hours of collection. This is not practical as sampling events take days or even weeks to complete. This is why the lab prefers to have samples frozen and shipped to the lab frozen. According to Method 200.3, section 8; Tissue can also be frozen at < -20 degrees Celsius. The lab uses the criteria of< -10 degrees Celsius for storage of frozen biota samples. The preparation of Stannous Chloride solution differs from EPA 245.1: automated mercury analyzers with reduced concentration of stannous chloride have been deemed equivalent. Prepare calibration standards as liquid standards. (This is different from Method 245.6 which specifies preparing calibration tissues directly in a tissue matrix). EPA 245.6 Rev.2.3 1991, section 6.10 describes a water bath as follows: The water bath should have a covered top and capacity to sustain a water depth of 2-in. to 3-in. at 95°C+1°C. Nowhere in the document is a temperature acceptance range given for the operating temperature of 58°C. The lab follows the criteria of +3°C from similar methodology of SW846 7471 B Rev.2 2007 and also uses a hot block. For EPA 245.6 Rev.2.3 1991, the lab has chosen to use a 0.6g sample volume instead of the method specified 0.2-0.3g in section 8.3. In section 11.1, 4 mL of conc. H2SO4 and 1 mL of conc. HNO3 are added. The lab uses 2.0 mL of conc. H2SO4 and 0.5 mL of conc. HNO3. In section 11.2 5 mL of potassium permanganate and 8 mL of potassium persulfate are added. The lab uses 7.5 mL of potassium permanganate and 4 mL of potassium persulfate. The lab has established this procedure for re-occurring project work with many years of historical. 15.0 RESPONSIBILITIES Pace ENV employees that perform any part this procedure in their work activities must have a signed Read and Acknowledgement Statement in their training file for this version of the SOP. The employee is responsible for following the procedures in this SOP and handling temporary departures from this SOP in accordance with Pace's policy for temporary departure.

Applicable analytes are listed in the Target Analyte List. 2.2 The sample is acidified with nitric acid and heated on an apparatus with additions of nitric acid, hydrogen peroxide, and hydrochloric acid. 2.3 The digestate is brought to a 50 mL final volume with reagent water, and either centrifuged, allowed to settle, or filtered. 2.4 This process is to extract the metals from the biota matrix so it can go through multi-element analysis by ICPMS. 3.0 INTERFERENCES 3.1 Cross contamination from standards and samples containing high concentrations is possible. It is critical that the metals digestion (prep) lab is kept in a clean organized manner to minimize any possible cross contamination. 3.2 Isobaric Polyatomic Interferences — Isobaric polyatomic interferences result when ions containing more than one atom have the same nominal mass-to-charge ratio as an analyte of interest and cannot be resolved by the instrument's spectrometer. An example includes CIO+ (mass 51), which interferes with V, and must be corrected by measuring CIO+ at mass 53. When possible, an interference free isotope should be chosen for measurement. 3.3 Chromic acid should never be used to clean any container used in metals analysis. 3.4 Borosilicate glass in sample containers can lead to interference of Boron concentrations in samples. This is also true of volumetric flasks, thus when dilution in the flask is complete the standards must be removed as soon as possible from the dilution container and placed into a clean plastic container. 4.0 DEFINITIONS Refer to the Laboratory Quality Manual for a glossary of common lab terms and definitions. 5.0 HEALTH AND SAFETY The toxicity or carcinogenicity of each chemical material used in the laboratory has not been fully established. Each chemical should be regarded as a potential health hazard and exposure to these compounds should be as low as reasonably achievable. The laboratory maintains documentation of hazard assessments and OSHA regulations regarding the safe handling of the chemicals specified in each method. Safety data sheets for all hazardous chemicals are available to all personnel. Employees must abide by the health, safety and environmental (HSE) policies and procedures specified in this SOP and in the Pace Chemical Hygiene /Safety Manual.

Samples should be collected in accordance with a sampling plan and procedures appropriate to achieve the regulatory, scientific, and data quality objectives for the project. The laboratory will provide containers for the collection of samples upon client request for analytical services. Bottle kits are prepared in accordance with laboratory SOP ENV-SOP-GBAY-0007 Bottle Preparation. 6.1 All sample containers must be HDPE, glass, or Teflon. The containers are purchased pre- cleaned and documented to be contaminant free. Where applicable, the bottle ware is demonstrated to be free of target analytes. When bottle ware not originating from the lab is used, the data may be qualified with either one or both of the following data qualifiers: 6.1.1 Sample field preservation does not meet EPA or method recommendations for this analysis. 6.1.2 Sample container did not meet EPA or method requirements. 6.2 General Requirements Matrix Routine Minimum Container Sample Amount' Preservation Holding Time Glass, Plastic, Plastic Zip-top Thermal:�6°C;<_-10°C when frozen Removal from freezer: Biota bags, or 5g Chemical:None 6 months,excluding Hg. aluminum foil 28 Days if Hg requested. 'Minimum amount needed for each discrete analysis. Thermal preservation is checked and recorded on receipt in the laboratory in accordance with laboratory SOP ENV-SOP-GBAY-0006 Sample Management (most recent revision or replacement). Chemical preservation is checked and recorded at time of receipt or prior to sample preparation. Shipments of soil and water samples to the laboratory require thermal preservation in the form of cubed, block or dry ice. At the time of laboratory receipt, proper thermal preservation is checked by measuring the temperature of melt water or when provided the temperature blank. The Pace Analytical acceptable temperature range is 0 to 6°C (or <_-10° for dry ice for biota samples). All QAPjP and regulatory authority requirements become priority over this requirement.

Refer to Pace SOP ENV-SOP-GBAY-0115 Support Equipment (most recent revision or replacement). 9.1.1.2 Daily Calibration Check 9.1.1.2.1 Clean the balance and surrounding area prior to starting the daily calibration check. 9.1.1.2.2 Check the sight level on the balance. If it needs adjusting, level the balance. 9.1.1.2.3 The weight set ID indicated in the logbook is used as the primary set. If an alternate weight set ID is used, that ID must be recorded in the comment section of the balance calibration logbook for that day. 9.1.1.2.4 Tare the balance before weighing the NIST certified weights. 9.1.1.2.5 Use forceps or other means to lift each weight (Do not touch the weights with fingertips as the residue may artificially adjust the true value of the weights). Record the date of the calibration check, the true value of the weight, and the actual measured weight in the logbook. Repeat this procedure for the other certified weights. If calibration weights differ from the certified weights by more than specified in the balance calibration logbook, corrective action must be taken. 9.1.1.3 Corrective Action 9.1.1.3.1 Clean the balance and balance pan. Check the sight level on the balance and adjust if necessary. Re-tare and reweigh all the certified weights. 9.1.1.3.2 The internal calibration function (if available) of the balance may be used as a means of corrective action. 9.1.1.3.3 Utilize the internal calibration function and diagnostics. Refer to instrument manual. 9.1.1.3.4 Contact the QA office for assistance if the balance does not meet the calibration tolerances. 9.1.1.3.5 If the above action does not correct the problem, the balance should be taken out of service and appropriately labeled to avoid improper usage. A service technician should be contacted. 9.1.1.3.6 Record any corrective action. Initial and date all entries in the logbook. 9.1.2 Thermometer - See the most recent revision of the SOP ENV-SOP-GBAY-0115, Support Equipment for thermometer calibration and validation.

A random well is used for each verification. The block has a full temperature evaluation performed minimally each year. The temperature will be record in the Electronic Prep Log in accordance with EPIC Pro Training Module 16: Electronic Prep Log Guide (most recent revision or equivalent). 9.2.2 Batch samples in the LIMS. Identify QC samples at the frequency stated in the Quality Control Section of this SOP. Additional samples may be added to the batch, so long as 1 the total sample number in the batch does not exceed 20. The digestion of the additional samples must begin within eight hours of the start of the original digestion. 9.2.3 Log into the Electronic Prep Log. Create a new prep sheet using the 3050B1ICP_ICPMS Soil Template and the LIMS Batch HBN. 9.2.4 Verify sample IDs and LIMs numbers on containers against the prep sheet. 9.2.5 To the extent possible, mix and crush the sample as per SOP ENV-SOP-GBAY-0129, Sample Homogenization, Compositing, and Sub-sampling (most recent revision or replacement), in the sample container with a disposable plastic spatula to achieve homogeneity. Tissue samples with sufficient sample volume are typically blended with liquid nitrogen to achieve a light fluffy texture. Small volume tissue samples and vegetative samples may be cut up. 9.2.6 Prepare Method Blank (MB) by leaving the digestion tube empty. 9.2.7 Prepare a Solid Matrix Blank (typically chicken) by weight 0.500-0.504g of blended chicken into one digestion tube. Record sample weight in digestion log. 9.2.8 Prepare an SRM by weighing exactly 0.500g of the SRM into one digestion tube. Record sample weight in digestion log. 9.2.9 Prepare Laboratory Control Spike (LCS) by weighing —0.500g of solid matrix material (typically chicken) in digestion tube. Add 1.0 mL of the Biota Spike and 1.0 mL of the Biota Spike Ag to the LCS digestion tube. Spikes may be adjusted based on client requests. 9.2.10 Laboratory Spike Duplicate (LCSD) if there is insufficient volume for an MS/MSD. The LCSD may be required per client request. 9.2.11 Prepare Matrix Spike / Matrix Spike Duplicate (MS/MSD), by weighing 0.500 to 0.504 grams of parent sample into 3 separate digestion tubes. Record sample weight to nearest 0.001 gram on digestion log. Parent, MS, and MSD should be approximately the same weight. Add 1.0 mL of the Biota Spike and 1.0 mL of the Biota Spike Ag to the MS/MSD digestion tubes. Spikes may be adjusted based on client request. 9.2.12 Weigh 0.500 to 0.575g of homogenized sample into a labeled digestion tube. Record sample weight to nearest 0.001 g on digestion log. Do this for each sample in the digestion batch. Record all information in the Electronic Prep Log worksheet. Note: If a sample contains a significant amount of water a larger mass may be used.

The method blank is processed through all clean-ups, etc., which were performed on the samples in the batch. For a method blank to be acceptable, in the absence of project specific criteria, the concentration shall not be higher than the highest of the following: The reporting limit, or ten percent of the regulatory limit of concern for that analyte, or ten percent of the measured concentration in a particular sample of interest. Each sample in the batch is assessed against the above criteria to determine if the sample results are acceptable. Any sample associated with an unacceptable blank is either flagged, re- prepped for analysis, or if re-prepping is not an alternative, the results are reported with the appropriate data qualifying codes. 11.1.2 LCS: A laboratory control sample (LCS) consists of a control matrix, which has been spiked, with the elements(s) of interest. Laboratory Control Samples are analyzed at a minimum of 1 per batch of 20 or fewer samples or preparation method. Results of the LCS are expressed in terms of percent recovery and are used to determine batch acceptance. 11.1.3 An LCS Duplicate may be analyzed to evaluate laboratory precision. The LCSD must also meet the criteria for the LCS. The Relative Percent Difference (RPD) will be calculated between the LCS and LCSD. NOTE: In the event where adequate sample is not supplied by the client to perform a Matrix Spike/ Matrix Spike Duplicate, the LCS and duplicate can lend insight on the precision of the analysis. 11.1.4 MS/MSD: Matrix spikes (MS and MSD) are performed to evaluate the effect of the sample matrix upon analytical methodology. A separate aliquot of sample is spiked with the element of interest and analyzed with the sample. 11.1.4.1 MS and MSD are performed at a minimum frequency of one pair in 20 samples per matrix type per sample preparation. 11.1.4.2 MS and MSD are done more frequently where regulations and client requests require. 11.1.4.3 The RPD between the MS and MSD is evaluated. 11.1.4.4 A matrix effect is indicated if the LCS data are within acceptance criteria, but the matrix spike data exceed the acceptance criteria. Prior to calculating recovery, the parent sample concentration (results <Reporting MDL = 0) is subtracted from the spike aliquot concentrations. 11.1.5 DUP — A Laboratory Duplicate is performed by client request; and is performed on a second aliquot of sample to evaluate consistency in the analytical procedure and in the sample matrix. 11.1.6 SRM — A Standard Reference Material is typically prepared and analyzed upon client request. It is a sample of known concentration chosen to resemble the matrix being analyzed. Any printed copy of this SOP and all copies of this SOP outside of Pace are uncontrolled copies.

Refer to Pace ENV corporate SOP ENV-SOP-CORQ-0011 Method Validation and Instrument Verification and to the laboratory's SOP ENV-SOP-GBAY-0106 Determination of LOD and LOQ (most recent revision or replacement) for these procedures. 11.2.1.2 The LOD and LOQ are always adjusted to account for actual amounts used and for dilution. 11.2.1.3 Current LOD and LOQ can be found in the Laboratory Information Management System (LIMS) - EpicPro. 11.2.1.4 Level of Detection (LOD): The LOD is determined by the 40CFR Part 136B MDL study. Once the 40CFR Part 136B MDL is determined it may be elevated if deemed unrealistic as demonstrated using method blank evaluations. 11.2.2 Periodic performance evaluation (PE) samples are analyzed per ENV-SOP- GBAY-0107, PE/PT Program (current revision or replacement), to demonstrate continuing competence. All results are stored in the QA office. At a minimum, these are performed twice a year for the aqueous and soil matrices. 11.3 Analyst Qualifications and Training Employees that perform any step of this procedure must have a completed Read and Acknowledgment Statement for this version of the SOP in their training record. In addition, prior to unsupervised (independent) work on any client sample, analysts that prepare or analyze samples must have successful initial demonstration of capability (IDOL) and must successfully demonstrate on-going proficiency on an annual basis.

If the MS and MSD fail precision control limits flag the parent with the appropriate precision data qualifier. 4. If the DUP fails precision control limits flag the parent with the appropriate precision data qualifier 5. Outside of client specific criteria,the SRM is digested and analyzed only to demonstrate analyte recovery in a standard reference material. When the recovery is outside the lab generated statistical limits,the element that failed recovery will be flagged in the samples for the element that failed.Client specific action may also exist. A specific SRM may also be requested by the client and with the lack of statistical evaluation of an SRM the default calculations of the existing SRM will be used due to software limitations. 1 13.0 POLLUTION PREVENTION AND WASTE MANAGEMENT Pace proactively seeks ways to minimize waste generated during our work processes. Some examples of pollution prevention include but are not limited to: reduced solvent extraction, solvent capture, use of reusable cycletainers for solvent management, and real-time purchasing. The EPA requires that laboratory waste management practice to be conducted consistent with all applicable federal and state laws and regulations. Excess reagents, samples and method process wastes must be characterized and disposed of in an acceptable manner in accordance with Pace's Chemical Hygiene Plan/Safety Manual. For further information on waste management, consult ENV-SOP-GBAY-0125 Waste Handling and Management(most recent revision or replacement). 14.0 MODIFICATIONS A modification is a change to a reference test method made by the laboratory. For example, changes in stoichiometry, technology, quantitation ions, reagent or solvent volumes, reducing digestion or extraction times, instrument runtimes, etc. are all examples of modifications. Refer to Pace ENV corporate SOP ENV-SOP-CORQ-0011 Method Validation and Instrument Verification for the conditions under which the procedures in test method SOPs may be modified and for the procedure and document requirements. 14.1 The elements listed in the scope as reportable from analysis of this digest is more extensive that those listed in SW846 3050B Rev.2 1996. All elements reported from this digestion procedure have passed the necessary method performance criteria. This includes MDL, IDOC, CDOC, and double-blind performance samples. 14.2 SW846 3050B Rev.2 1996 section 4.8 describes the Heating source as Adjustable and able to maintain a temperature of 90-95°C. The lab follows the temperature criteria in the Procedure section 7.2 of 95°C±5°C. 14.3 Digestion occurs in 50 mL digestion tubes. These offer more refluxing action than a beaker even when uncovered. Digestion occurs with a ribbed watch glass. This allows for added refluxing while still allowing volume reduction. This is why the procedure uses the time limits instead of the volume reductions. Any printed copy of this SOP and all copies of this SOP outside of Pace are uncontrolled copies. Uncontrolled copies are not tracked or replaced when new versions are released, or the SOP is made obsolete. Users of the SOP should verify the copy in possession is the current version of the SOP before use.

The sample aliquot has been adjusted to use 0.500 — 0.575 g in place of 1.0 g. All standards and reagents have been reduced to ensure that the ratios are still consistent with the procedure. 14.5 If a client fails to provide sufficient volume for the method required Matrix Spike/Matrix Spike Duplicate (MS/MSD), the laboratory will analyze a Laboratory Control Spike Duplicate to demonstrate precision. The analytical batch will be qualified with the "M5"data qualifier. 14.6 SW846 3050B Rev.2 1996 section 6.3 describes storage as: Non-aqueous samples should be refrigerated upon receipt and analyzed as soon as possible. No target temperature or range is specified. The lab practice is to have thermal preservation at 5.6°C. This is based on 40CFR Part 136, page 29808, footnote 18. Chapter Three Rev. 4 2007 TABLE 3-2 while not providing a temperature for most metals, does provide a storage temperature for Hg and Hexavalent Cr in solids of .6°C. 14.7 SW846 3050B Rev.2 1996 was written targeting a wet sample amount of 2.0 g. The lab targets 0.50 g of sample. The acid and peroxide reagent volumes used have been adjusted to the maximum amount used in the method resulting in a final acid matrix of 10% HNO3 and 5% HCI. This is a very high acid matrix but provides an aggressive digestion while maintaining consistent acid matrix that is required for analysis. This also keeps the acid matrix consistent with batch QC and method QC such as LOD studies. 14.8 SW846 3050B Rev.2 1996 Section 7.2 describes the HNO3 addition being done in multiple steps. First a 1:1 addition followed by subsequent additions of concentrated HNO3. The lab SOP is to add all of the HNO3 in a single step but maintain the amount of acid digesting the sample during the 2-hour digest in this section. Samples that are visibly high organic material or continue to give off brown fumes at the end of the Section 7.2 2-hour heating period will be re- set with a lower sample volume that is more applicable to the acid amounts being used. 14.9 SW846 3050B Rev.2 1996 section 7.5 and 7.5.2 both have the final step in the digestion process as filtering. The lab will centrifuge the samples to eliminate/minimize and undissolved solids present after digestion. This reduces the possibility of increasing the background for target elements. There are only a few instances where there is any solid or sediment remaining after the digestion is complete. 15.0 RESPONSIBILITIES Pace ENV employees that perform any part this procedure in their work activities must have a signed Read and Acknowledgement Statement in their training file for this version of the SOP.

This procedure is restricted to use by, or under the supervision of, technicians experienced in the preparation of samples. 2.0 SUMMARY OF METHOD Solid, liquid, or biological samples are thoroughly mixed or blended to ensure that any aliquots taken are representative of the sample as a whole. The samples are mixed in either their original containers or, in the event that original container does not allow for adequate mixing, transferred to an inert container for thorough homogenization. Necropsy and/or filleting of whole-body animals may be performed to isolate the individual organs or portions of the specimen to be homogenized and utilized for analysis. This SOP involves instruction to chop, grind, and blend plant materials, biological tissue, sediment and synthetic materials into a homogenized sample compatible with preparation of semi volatile organic extracts and metals digestates. Analysts must make reasonable judgments when sub-sampling materials in order to obtain a homogenous, representative aliquot of the material. Because of the nature of environmental samples, the analyst may have to treat samples on a case-by-case basis ensuring that all aspects of the analytical method are performed. In the event that the analyst cannot reasonably determine what constitutes a representative sample, the project manager or supervisor must be involved so that the client can help ensure an appropriate representative aliquot is utilized. 3.0 INTERFERENCES Metallic Devices—Samples to be analyzed for metal constituents must not be homogenized using any metallic mixing devices or containers as it may result in contamination of the sample with a variety of metals. Use only glass, plastic or ceramic materials when working with these sample types. This may not be applicable for tissue samples since metallic devices (blenders, etc.) may be necessary for grinding and chopping prior to sample homogenization. Plastic Devices — Samples to be analyzed for organic constituents must not be homogenized using any plastic mixing devices or containers as it may result in both positive and negative interferences. Use only glass and ceramic devices when working with these sample types. Metal instruments may also be used if analysis for metals is not required from the same sample Solvents, reagents, glassware, and other sample processing hardware may yield discrete artifacts and/or elevated baselines causing misinterpretation of the analytical results. All these materials must be free from interferences under the conditions of the analysis, demonstrated by performing method blanks. Any printed copy of this SOP and all copies of this SOP outside of Pace are uncontrolled copies. Uncontrolled copies are not tracked or replaced when new versions are released, or the SOP is made obsolete. Users of the SOP should verify the copy in possession is the current version of the SOP before use.

Biota-the flora or fauna of a region. Composite-combining the typical or essential characteristics of individuals, making up a group. Fillet- to cut an edible portion of fish. This may or may not contain the ribcage and belly flap and is dependent upon the regulatory, scientific, and data quality objectives for the project. Head-the upper or anterior division of the animal body that contains the brain, the chief sense organs, and the mouth. 5.0 HEALTH AND SAFETY The toxicity or carcinogenicity of each chemical material used in the laboratory has not been fully established. Each chemical should be regarded as a potential health hazard and exposure to these compounds should be as low as reasonably achievable. The laboratory maintains documentation of hazard assessments and OSHA regulations regarding the safe handling of the chemicals specified in each method. Safety data sheets for all hazardous chemicals are available to all personnel. Employees must abide by the health, safety and environmental (HSE) policies and procedures specified in this SOP and in the Pace Chemical Hygiene / Safety Manual. Personal protective equipment (PPE) such as safety glasses, gloves, and a laboratory coat must be worn in designated areas and while handling samples and chemical materials to protect against physical contact with samples that contain potentially hazardous chemicals and exposure to chemical materials used in the procedure. Hearing protection should be worn when a blender is in operation, or during sediment processing when applicable. Liquid Nitrogen presents additional hazards and may cause cryogenic burns or displace oxygen and cause rapid suffocation. Use in a well-ventilated area with additional PPE designed for handing these materials. Contact your supervisor or local HSE coordinator with questions or concerns regarding safety protocol or safe handling procedures for this procedure.

Samples should be collected in accordance with a sampling plan and procedures appropriate to achieve the regulatory, scientific, and data quality objectives for the project. The laboratory will record any nonconformance to these requirements in the laboratory's sample receipt record. Details concerning sample shipping, preservation and storage can be found in the applicable extraction and/or analytical SOPs, or as specifically discussed below. Samples must be stored separately from all standards and reagents. Where possible, samples for trace analysis should be segregated from highly contaminated samples to avoid cross contamination. Food or drink products must always be kept away from samples and never stored in the same area with samples. Biota samples must be kept frozen at .-10°C in their original sample containers until the homogenization process occurs. Small rodents must undergo a special procedure to destroy any Hantavirus which may be present. Refer to the Pace SOP: ENV-SOP-GBAY-0130 Small Rodent Handling and Homogenization (most recent revision or replacement)for details. After homogenization, biota samples are kept frozen at 5..-10°C in glass jars sized closest to the prepared homogenate sample volume. Individual jars of samples are grouped together as appropriate and stored in a labeled cardboard box within the freezer. Sediment samples which will be air-dried are received at <_6°C. After the dry and grind procedure is completed the samples are retained at room temperature. Synthetic materials may be kept at room temperature. 7.0 EQUIPMENT AND SUPPLIES 7.1 Equipment Table 7.1: General Laboratory Homogenization Equipment and Supplies Supply Vendor* Model /ID* Catalog#* Description Spatula Fisher Stainless Steel S50822 - Spatula Fisher Cooper Surgical Inc 11080 Plastic scrapers Analytical Balance Varied Capable of weighing NA Analytical or top nearest sensitivity loading Sample Mixing Varied Metal, plastic, glass or NA Dependent upon Containers ceramic sample composition *Or equivalent Any printed copy of this SOP and all copies of this SOP outside of Pace are uncontrolled copies.
