Carolina Amec Foster Wheeler Project No. 7810160654 Page 1 of 14 Executive Summary The following Water Quality Monitoring Plan (WQMP) – Revised July 28, 2016, represents the second 5-year update to the WQMP for the Duke Energy (Duke) Flue Gas Desulfurization (FGD) Residue Landfill at Marshall Steam Station. The original WQMP was approved in November 2006. The current WQMP (the first 5-year update) was prepared by Altamont Environmental, Inc. (Altamont) and titled Groundwater Sampling and Analysis Plan, dated August 19, 2011. The current Permit to Operate is scheduled to expire on November 21, 2016. As part of the permit amendment (renewal), Amec Foster Wheeler was requested to review and update the current WQMP as needed per the requirements stated in 15A NCAC 13B .0504 (1)(g)(iv). The water quality monitoring network remains unchanged for the Marshall FGD Landfill facility since the last update; therefore, the overall content of the current WQMP remains relevant and applicable. In general, Amec Foster Wheeler retained Altamont’s 2011 plan content and organization for this WQMP update with the exception of the following revisions: Minor text edits, primarily changing absolute terms to qualifier terms Updated Department of Environment and Natural Resources (DENR) references to Department of Environmental Quality (DEQ) Table 1 total depths for MS-8 and MS-16 were revised to reflect the bottom of the well and not the bottom of the borehole. Table 2 detection limits column was removed since it is lab-specific. Detection limits are generally specified by the analytical methods which are still listed. Table 2 dissolved oxygen (DO) and oxidation reduction potential (ORP) rows were added under in situ parameters. Table 2 analytical method for in situ parameters was changed to “Multi-Parameter Water Quality Meter” and “Turbidimeter” as appropriate instead of listing a specific brand of equipment. Table 2 units were changed for chloride, fluoride, nitrate, sulfate, and total dissolved solids from micrograms per liter to milligrams per liter, which is the more common laboratory reporting format for those parameters. Table 2 and 3 parameters Antimony, Beryllium, Thallium, and Vanadium were added as requested in a Permit to Operate Renewal Application letter from the North Carolina Department of Environmental Quality (DEQ), Division of Waste Management (DWM), Solid Waste Section (SWS) dated June 17, 2016. Table 2 and 3 parameter Cobalt was added as requested in an email to Mr. Mark Shumpert of Amec Foster Wheeler from Ms. Tyler Hardin of Duke Energy dated July 19, 2016. Table 3 ORP row added under in situ parameters. Table 3 holding times corrected from 6 months to 28 days for mercury and fluoride.

Amec Foster Wheeler NC Geology Firm License C-247 Water Quality Monitoring Plan – July 28, 2016 Duke Energy – Marshall Steam Station MSS FGD Landfill-Permit No. 18-09 Terrell, North Carolina Amec Foster Wheeler Project No. 7810160654 Page 3 of 14 1 Program Description 1.1 Scope of Work This Water Quality Monitoring Plan (WQMP) is designed to guide the monitoring efforts that are used to evaluate the effects of the Marshall Steam Station (Marshall) Flue Gas Desulfurization (FGD) Residue Landfill, Phase 1, Cell 1, on the groundwater in the area. This plan has been prepared according to the guidelines set forth by the North Carolina Department of Environmental Quality (DEQ) Water Quality Guidance Document for Solid Waste Facilities (SW- 1001-87), and by the Environmental Protection Agency (EPA) in "Interim Guidelines and Specifications for Preparing Quality Assurance Plans" (QAMS-500/80), and documents the methodologies of field sampling, record-keeping protocols, data quality objectives, and data validation procedures that will be used in this program. 1.2 Background and Site Hydrogeological Description Marshall Steam Station (Marshall) is located in Catawba County, on Highway NC 150, just west of Lake Norman. The station is owned and operated by Duke Energy Carolinas, LLC (Duke). Marshall is located in the Piedmont physiographic region. Figure 1 shows the location of the plant and the location of the FGD landfill, Phase 1, Cell 1. The Marshall Steam Station has a generating capacity of 2,090 megawatts (MW) of electric power by the combustion of coal. Therefore, the Marshall station generates enough electricity to power over one-and-a- half million homes. The FGD Residue Landfill will consist of two cells. When completed, the landfill footprint will contain approximately 31.9 acres. Construction of Cell 1 was completed in 2006, and a Permit to Operate was issued on November 21, 2006. Duke has not requested a Permit to Construct for Cell 2. Cell 1 has a footprint of approximately 14.8 acres. In general the landfill is permitted to receive industrial wastes generated by Duke at Marshall and at other Duke facilities. The waste received at the FGD residue landfill consists primarily of gypsum. The FGD residue is conveyed to the landfill site by truck, where the material is spread and compacted. The landfill was constructed with a leachate collection and removal system and an engineered liner system to prevent impacts to groundwater. When closed, the completed landfill will receive an engineered cover system to reduce infiltration. The FGD landfill is located entirely on Duke property, northwest of the Marshall Station and to the west of the Marshall Ash Basin. The landfill is located to the east of a north-south trending railroad line. . Located to the west of this railroad line is Sherrill’s Ford Road, which also runs north-south along a surface water divide. Located between the landfill footprint and the railroad line is a surface water drainage feature. This feature drains to the south, to an intermittent stream that drains to Lake Norman. There is a topographic divide running north-northwest through the landfill footprint, along Steam Plant Road. Surface drainage to the west of Steam Plant Road drains to the surface drainage feature and surface drainage to the east of Steam Plant Road drains to the Marshall Ash Basin. Water Quality Monitoring Plan – July 28, 2016 Duke Energy – Marshall Steam Station MSS FGD Landfill-Permit No. 18-09 Terrell, North Carolina Amec Foster Wheeler Project No. 7810160654 Page 4 of 14 As described in the site hydrogeological study (Hydrogeological Study FGD Scrubber Landfill, Duke Power-- Marshall Steam Station, Terrell, North Carolina, S&ME Project No: 1264-02-578, May 30, 2003), the subsurface conditions in the landfill area consist of residual soils and partially to fully weathered rock (saprolite) , which have formed by the in- place weathering of the parent rock. As is typical in the groundwater systems located in the Piedmont region, groundwater at the landfill site occurs within the residuum and saprolite under unconfined aquifer conditions. The predominant discharge areas for groundwater in the landfill area are expected to be the drainage feature and the ash basins located to the east of the landfill. The subsurface conditions at the landfill were described by S&ME as follows: Residuum: Beneath the ground surface, residual material consisting of silts, silty clays, clayey silts, and silty sands. Sandy silts were found at depths ranging from 2.5 to 14 feet below ground surface. Saprolite: Saprolite material was found at depths ranging from 13.5 feet to 68.5 feet below ground surface. This material is a product of weathered bedrock, consisting of silts to clayey silts and sandy silts to silty sands, having a Standard Penetration Test (SPT) resistance of 50 blows per foot or more. Partially Weathered Rock: This material is defined as material exhibiting SPT resistances in excess of 100 blows per foot. This material was found at depths ranging from 25.5 feet to 90 feet below ground surface. Bedrock: Bedrock was found at depths ranging from 25.5 feet to 79.5 feet. When sampled, this material was classified as granite, schist, and gneiss. Horizontal to high- angle fractures were found in the upper ten feet of the bedrock areas. Many fractures were found to be iron stained, indicating flow of water into the fractures. 1.3 Well Locations and Installation Groundwaterandsurfacewater conditionsat the landfill aremonitoredusingninegroundwater monitoring wells and one surface water sampling location. Monitoring well locations and construction information are provided in Table 1. The locations of these wells are shown on Figure 2. Monitoring well MS-8 will be used as the backgroundwell for this sampling program. The wells were constructed of two-inch diameter polyvinyl chloride (PVC) well screen and casing. The well screens were placed where they would intercept the aquifer and have slot sizes of 0.010 inch. The screen lengths are shown in Table 1. The wells were installed by a well driller registered in North Carolina in accordance with applicable DEQ regulations. The locations of the wells and the elevations of the tops of the casings were surveyed under the direction of a Professional Surveyor, licensed in North Carolina. Figure 3 shows a typical construction diagram for the wells. Each well is equipped with dedicated bladder- type pump systems. Well construction records for the existing wells are included in Appendix A. A brief description of the monitoring locations and their monitoring function is provided below. Water Quality Monitoring Plan – July 28, 2016 Duke Energy – Marshall Steam Station MSS FGD Landfill-Permit No. 18-09 Terrell, North Carolina Amec Foster Wheeler Project No. 7810160654 Page 5 of 14 Monitoring Well MS-8—BackgroundWell Monitoring well MS-8 will be used as a background monitoring well.

This surface water sampling location is located south of the landfill, between wells MS-12 and MS-13, as shown on Figure 2. The North Carolina State Plane coordinates and elevation for this sampling location are shown in Table 1.1. Water Quality Monitoring Plan – July 28, 2016 Duke Energy – Marshall Steam Station MSS FGD Landfill-Permit No. 18-09 Terrell, North Carolina Amec Foster Wheeler Project No. 7810160654 Page 6 of 14 1.5 Monitoring Frequency The wells and surface water sample location will be sampled semiannually in March and September. 1.6 Parameters The parameters to be sampled and analyzed, units of measure, and analytical methods are presented in Table 2. 1.7 Data Quality Objectives The overall Quality Assurance (QA) objective is to provide reliable data of known and acceptable quality. Measurements will be documented to yield results that are representative of the groundwater and surface water quality. Data will be calculated and reported in units as required by DEQ. The analytical QA objectives for precision, accuracy, and completeness have been established by the laboratories in accordance with EPA or other accepted agencies for each measurement variable, where possible. The objectives are outlined in the Duke Energy Analytical Laboratory Procedures Manual and are available upon request. Detection limits for the water analyses are generally specified by the analytical method. As stated above, appropriate methods have been selected to meet applicable standards for groundwater quality. Instances may occur, however, in which the condition of the sample may not allow detection of the desired limits for various parameters either because of matrix interference or elevated analyte concentrations requiring sample dilution. The laboratory(s) will provide sufficient documentation with each data package to notify reviewers about any analytical issues with the data, if needed. 2 Sampling Procedures 2.1 Sampling Equipment Development, purging, and sampling equipment are selected so that materials are compatible with the sample parameters and comply with state and federal regulatory requirements for sampling. Positive-gas- displacement fluorocarbon resin bladder pumps are installed in each monitoring well and are dedicated purging and sampling systems. 2.1.1 Equipment Cleaning Procedures Dedicated sampling equipment has been installed in each monitoring well. In the event non- dedicated equipment is used between wells, equipment will be cleaned before and after use in each well in accordance with standard EPA-approved cleaning procedures for field equipment. This standard is outlined in the Standard Operating Procedures and Quality Assurance Manual, Engineering Support Branch, EPA Region IV, February 1, 1991. Water Quality Monitoring Plan – July 28, 2016 Duke Energy – Marshall Steam Station MSS FGD Landfill-Permit No. 18-09 Terrell, North Carolina Amec Foster Wheeler Project No. 7810160654 Page 7 of 14 2.2 Groundwater Sampling 2.2.1 Development of Wells Each of the nine wells addressed in this WQMP have been developed. If new wells are installed they will be developed before they are sampled. After installation of new wells, and prior to initial sampling, the monitoring wells will be developed. Development reduces silt that has settled into the bottom of the well following installation, and reduces fine silt and clay particles from the well screen and sandpack surrounding the screen. Well development is performed to reduce potential for clogging and promote well performance. Development involves removing an estimated ten or more well volumes from the well using a positive-gas-displacementfluorocarbon resin bladder pump with up-and-down agitation to loosen particles from the well screen. After development of a well, a true well depth is recorded, referenced to the top of well casing (TOC). 2.2.2 Groundwater Level and Total Depth Measurements Water level measurements are collected and recorded to determine the groundwater elevations, determine groundwater flow direction, and to calculate the volume of standing water in the well. Each monitoring well has been surveyed to determine the elevation of the TOC. Total well depth and water level measurements are referenced to the TOC and recorded to the nearest one-hundredth of a foot. Water level measurements are collected with an electronic measuring device consisting of a spool of dual conductor wire and sensor. When the sensor comes in contact with water, the circuit is closed and a meter light and/or buzzer is attached to the spool to signal the contact. The sensor is lowered further until it rests on the bottom of the well to determine the total depth of the well reference to the TOC. The depth and water level measurements are used to verify that the well has not filled with silt and to calculate the volume of water in the well. The volume of well water (in gallons) is calculated using the following equation: V=h*πr2 * (7.48052 gal/ft 3) where V = volume of water in the well screen and casing (gallons) h = height of standing water (feet) = total well depth – water level r = radius of well casing (feet) In dedicated sampling systems, an accurate well depth is determined, as indicated above, after development of the well and prior to installation of the dedicated bladder pump. The well depth, water level measurement,and calculated well volume are recorded on the Groundwater Monitoring Data Sheet (Figure 4). 2.2.3 Well Purging and Sampling The selection of purging technique is dependent on the hydrogeologic properties of the aquifer and hydraulic characteristics of each well. Hydraulic conductivity, water column, well volume, screen length, and other information are evaluated to select the purging technique to acquire Water Quality Monitoring Plan – July 28, 2016 Duke Energy – Marshall Steam Station MSS FGD Landfill-Permit No. 18-09 Terrell, North Carolina Amec Foster Wheeler Project No. 7810160654 Page 8 of 14 groundwater representative of the aquifer conditions. The Groundwater Monitoring Data Sheet (Figure 4) is used to record purging methods and measurements. A multi-parameter water quality monitoring instrument is used to measure field stabilization or indicator parameters for determining representative groundwater during purging. These instruments measure pH, specific conductance, temperature, dissolved oxygen (DO), and oxidation-reduction potential (ORP). Instrument calibration must be performed and documented before and after each sampling event. The pH subsystem will be calibrated with two pH standards (pH 7.0 and 4.0) bracketing the expected groundwater pH. The specific conductance subsystem will be calibrated using two standards bracketing the expected groundwater conductivity. Calibration results will be recorded on a Field Sampling Calibration Form (Figure 5). Various well purging techniques are described below. Currently, each well is fitted with dedicated pumps. The purging method utilized at any particular well will be selected after considering the characteristics of the well and the purging method(s) used during previous sampling events. Conventional Purging This technique entails removing one equivalent well volume and measuring the indicator parameters (temperature, pH, and specific conductance). When the parameters have stabilized to within ±0.2 pH units and ±10% for temperature and conductivity over three to five well volumes, representative groundwater has been achieved for sampling. It is acceptable to begin sampling after five complete well volumes have been removed, even when indicator parameters have not stabilized. Groundwater is pumped into a graduated container to measure the volume of water purged. Under normal rates of recovery, samples should be collected immediately after purging, in accordance with EPA guidelines. For low-yield wells, incapable of yielding three to five well volumes in a reasonable amount of time (e.g., 2 hours or less), groundwater is purged to the elevation of the pump intake while measuring indicator parameters. Typically, low-yield wells are evacuated to dryness one time and sampled when sufficient water level recovery occurs. Low-Flow Purging Low-flow purging and sampling are appropriate when the recharge rate of the well approximates or equals the discharge rate of the pump with minimal drawdown of the water column (≤1 foot). During low-flow purging and sampling, groundwater is pumped into a flow-through chamber at flow rates that stabilize water level drawdown within the well. Indicator parameters are measured over time (usually at five-minute intervals). When parameters have stabilized within ±0.2 pH units and ±10% for temperature, conductivity, and DO, and ±10 milli-Volts (mV) for ORP over three consecutive readings, representative groundwater has been achieved for sampling. Turbidity is not included as a stabilization parameter, but turbidity levels of 10 nephelometric turbidity units (NTU) or less should be targeted. Water Quality Monitoring Plan – July 28, 2016 Duke Energy – Marshall Steam Station MSS FGD Landfill-Permit No. 18-09 Terrell, North Carolina Amec Foster Wheeler Project No. 7810160654 Page 9 of 14 Modified Low-Flow Purging This technique is considered a viable option particularly in the Piedmont region due to clay soils where water level drawdown cannot be stabilized while pumping. When the well recharge rate is less than the pump discharge rate, excessive drawdown (> 1 foot) of the water column occurs and mixes with stagnant water located above the screened interval. One equivalent well volume is removed initially before measuring indicator parameters. Frequently, removal of the initial well volume reduces the hydraulic head and allows for matching of the recharge rate with the pumping rate, providing stabilization of drawdown. Indicator parameters should be measured, at five-minute intervals, using a flow-through chamber attached to a multi-parameter water quality instrument.When parameters have stabilized to within ±0.2 pH units, ±10% for temperature, conductivity, and DO, and ±10 mV for ORP over three consecutive readings, representative groundwater has been achieved for sampling. Turbidity is not included as a stabilization parameter, but turbidity levels of 10 NTU or less should be targeted. Very Low Yield Well Purging This technique provides the best option for wells that historically purge to dryness and do not sufficiently recharge to provide adequate volume for sample collection. The volume of the pumping system (i.e., the pump bladder, tubing, and flow-through chamber) is calculated for removal. Two volumes will be removed by the pumping system if pumping occurs at the lowest possible rate (≤100 milliliters per minute [mL/min]). Indicator parameters will be measured and recorded initially, and then sample collection will begin. 2.2.4 Sample Collection After representative groundwater has been obtained by purging and the indicator parameters have stabilized,sampling may begin. Sampling personnel must wear new, clean, disposable, non-powdered latex or nitrile gloves during sample collection for each well. Samples are collected in the following order: Metals Sulfate and chloride Nitrate Total dissolved solids Pertinent notations, water-level measurements, removed well volumes, and indicator parameters are documented on the Groundwater Monitoring Data Sheet. 2.2.5 Sample Containers, Volume, Preservative, and Holding Time Sample containers supplied by the laboratory for the collection of groundwater samples shall be new and precleaned, as approved by EPA procedures appropriate for the parameters of interest. Table 3 summarizes the sample containers, sample volume, preservation procedures, and holding times required for each type of sample and parameter. Sample containers are kept closed until used. Sample containers are provided by Duke or vendor laboratories. Water Quality Monitoring Plan – July 28, 2016 Duke Energy – Marshall Steam Station MSS FGD Landfill-Permit No. 18-09 Terrell, North Carolina Amec Foster Wheeler Project No. 7810160654 Page 10 of 14 2.3 Surface Water Sampling Surface water samples are collected using techniques and equipment that provide representative characteristics of the water body being investigated and reduces the chance for sample contamination. Typically, samples are collected by grab or peristaltic pump. When filling a sample container by grab, use new, clean, non-powdered latex or nitrile gloves. Grasp the sample container by the lower half and position the container opening to face upstream. When using a peristaltic pump to collect a surface water sample, position the intake opening above the stream bottom to reduce the potential for collecting sediment. Run the pump for several minutes so that representative water is being collected after positioning the intake opening. 2.4 Sample Tracking The Chain-Of-Custody (COC) program allows for tracing the possession and handling of individual samples from the time of field collection through laboratory analysis and report preparation. Samples are pre-logged prior to sample collection. This process assigns a unique tracking number for each sample and generates corresponding labels. An example of the COC Record is provided as Figure 6. 2.5 Sample Labeling Sample containers are pre-labeled and organized prior to field activities as part of the pre- sampling staging process. As samples are actually collected, the sampling personnel write the following information directly on the label: sampling date and time, and initials of sample collector. This information is also recorded on the Groundwater Monitoring Data Sheet (Figure 4) and the COC Record (Figure 6). 2.6 Field Documentation Field documentation from each sampling event is recorded on the Groundwater Monitoring Data Sheets, the Field Sampling Calibration Form, and the Chain-of-Custody Record. These sheets are arranged in sequential order and filed by project and date. Additionally, a Groundwater Sampling Site Checklist (Figure 7) is completed indicating information of the monitoring well such as proper identification (ID) tag, condition of protective casing and pad. Field notations are made during the course of the field work to document the following information: Identification of well Well depth Static water level depth and measurement technique Presence of immiscible layers and detection method Well yield—high or low Purge volume or pumping rate Sample identification numbers Water Quality Monitoring Plan – July 28, 2016 Duke Energy – Marshall Steam Station MSS FGD Landfill-Permit No. 18-09 Terrell, North Carolina Amec Foster Wheeler Project No. 7810160654 Page 11 of 14 Well evacuation procedure/equipment Sample withdrawal procedure/equipment Date and time of collection Types of sample containers used Identification of replicates or blind samples Preservative(s) used Parameters requested for analysis Field analysis data and methods Sample distribution and transporter Field observations during sampling event Name of sample collector(s) Climatic conditions including estimate of air temperature Recorded entries are made in indelible ink. Errors should be corrected by drawing one line through the error, initialing and dating the correction, and starting a new entry on the next line (if necessary). 2.7 Chain-of-Custody Record The chain-of-custody (COC) Record (Figure 6)accompanies the sample(s), traces sample possession from time of collection to delivery to the laboratory(s), and clearly identifies which sample containers have been designated for each requested parameter. The record includes the following types of information: Sample identification number Signature of collector Date and time of collection Sample type (e.g., groundwater, immiscible layer) Identification of well Number of containers Parameters requested for analysis Preservative(s) used Signature of persons involved in the chain of possession Inclusive dates of possession Water Quality Monitoring Plan – July 28, 2016 Duke Energy – Marshall Steam Station MSS FGD Landfill-Permit No. 18-09 Terrell, North Carolina Amec Foster Wheeler Project No. 7810160654 Page 12 of 14 2.8 Sample Custody, Shipment, and Laboratory Receipt For the purpose of these procedures, a sample is considered in custody if it is: In actual possession of the responsible person In view, after being in physical possession Locked or sealed in a manner so that no one can tamper with it, after having been in physical custody; or in a secured area, restricted to authorized personnel Samples are maintained in the custody of the sampling crew during the sampling event. At the end of each sampling day and prior to the transfer of the samples off-site, COC entries are completed on the COC for each sample. Upon transfer of custody, the COC form is signed by a sampling crew member, including the date and time. If outside vendor laboratories are utilized, samples are delivered to these facilities by Duke personnel or courier. COC forms received by the laboratory(s) are signed and dated by the respective supervising scientist(s) or their designee (at the Duke Energy lab), or the laboratory sample custodian (at vendor labs) immediately following receipt by the laboratory. The analysts at the laboratory(s) maintain a sample-tracking record that will follow each sample through each stage of laboratory processing. The sample tracking records show the date of sample extraction or preparation, and analysis. These records are used to determine compliance with holding time limits during lab audits and data validation. Custody procedures followed by Duke laboratory personnel are described in detail in the Duke Energy Laboratory Services Procedures Manual. 3 Analytical Procedures The main analytical laboratory used in this program is the Duke Energy Laboratory Services Laboratory, which has North Carolina Drinking Water (NC37804) and Wastewater (#248) Certifications. The organizational structure and staff qualifications of the laboratory are discussed in its generic Quality Assurance Program (QAP). The QAP and Laboratory Services Procedures Manual are available for review upon request. Vendor laboratories that meet EPA and North Carolina certification requirements may be used for analyses which cannot be performed in-house. The analytical procedures are listed in Table 2. Indicator parameters are measured in the field according to:Duke Energy Scientific Services Section Quality Assurance Plan and Procedure 3210.X.1 4 Internal Quality Control Checks Internal laboratory quality control (QC) checks used by the laboratories are described in their generic QAP and procedures manual. The laboratories demonstrate the ability to produce acceptable results using the methods specified. 1 “X” indicates the most current version of the procedure Water Quality Monitoring Plan – July 28, 2016 Duke Energy – Marshall Steam Station MSS FGD Landfill-Permit No. 18-09 Terrell, North Carolina Amec Foster Wheeler Project No. 7810160654 Page 13 of 14 Internal quality control checks for sampling procedures and laboratory analyses will be conducted with each sampling event. These checks will consist of the preparation and submittal of field blanks, trip (travel) blanks,and/or field replicates for analysis of each parameter at frequencies described in the laboratory(s) procedures manuals. Equipment rinsate blanks for laboratory-cleaned equipment will be collected quarterly. The field QC blanks and replicates may be included as internal QC checks are described as below. The specific type and number of blanks used may vary depending on the sampling event and will be determined by the Duke field sampling personnel: Field Blanks: A field blank consists of a sample container filled in the field with organic- free, deionized, or distilled water prepared and preserved in the same manner as the samples. The field blank is transported to the laboratory with the samples and analyzed along with the field samples for the constituents of interest to check for contamination imparted to the samples by the sample container, preservative, or other exogenous sources. Trip Blanks: A trip (travel) blank is a sample container filled with organic-free water in the laboratory that travels unopened with the sample bottles. It is returned to the laboratory with the field samples, and analyzed along with the field samples for parameters of interest. Field Replicates: A field replicate is a duplicate sample prepared at the sampling locations from equal portions of each sample aliquots combined to make the sample. Both the field replicate and the sample are collected at the same time, in the same container type, preserved in the same way, and analyzed by the same laboratory as a measure of sampling and analytical precision. Equipment Blanks: If non-dedicated equipment is used between wells, it is recommended that equipment blanks be collected. The field equipment is cleaned following documented cleaning protocols. An aliquot of the final control rinse water is passed over the cleaned equipment directly into a sample container and submitted for analyses. 5 Validation of Field Data Package The field data package includes complete field records and measurements developed by the sampling team personnel. The field data package validation procedure consists of the following: A review of field data contained on the Groundwater Monitoring Data Sheet for completeness Verification that equipment blanks, field blanks, and trip blanks were properly prepared, identified, and analyzed A check of the Field Sampling Calibration Form for equipment calibration and instrument conditions Water Quality Monitoring Plan – July 28, 2016 Duke Energy – Marshall Steam Station MSS FGD Landfill-Permit No. 18-09 Terrell, North Carolina Amec Foster Wheeler Project No. 7810160654 Page 14 of 14 A review of the Chain-Of-Custody Record for proper completion, signatures of field personnel and the laboratory sample custodian, dates, and for verification that the correct analyses were specified. 6 Validation of Laboratory Data The laboratory will perform a validation review of the submitted samples and analytical results to check that the laboratory QA/QC requirements are acceptable. 7 Report Submittal A report of monitoring results will be submitted to the DEQ Division of Waste Management (DWM) within 120 days following the date of sampling. The report submittal will consist of the following: Environmental Monitoring Reporting Form (DEQ Form) Table of Detections and Discussion of 2L Exceedances Groundwater Elevation Contour Map Electronic Data Deliverable (EDD) in Excel Format DEQ will be notified in the event that vendor lab analyses have not been completed within this time frame. The Groundwater Monitoring Data Sheet, Field Calibration Forms, Chain-of- CustodyRecords, Laboratory(s) QA data, and Data Validation Checklists are kept on file by Duke and are available upon request.
