The purpose of this document is to establish procedures for monitoring groundwater in the uppermost aquifer, surface water in the vicinity of the landfill, and leachate during operational and post -closure periods. The WQMP is designed to provide information to the North Carolina Department of Environmental Quality (NCDEQ) - Solid Waste Section (SWS) and the landfill owner and operations personnel to evaluate potential effects on groundwater and surface water quality. The pertinent geologic and hydrogeologic characteristics of the Site, as described in the Site Study Report Volume II — Hydrogeologic Report (April 2019), prepared by Geosyntec Consultants, Inc. are summarized herein. 1.1 Site Description The 12.5-acre landfill is generally bounded by a former railroad spur to the south, the former coal-fired power plant area and Lake Julian to the east, undeveloped land to the north, and Interstate 1-26, wetlands, and the French Broad River to the west (Appendix I, Drawing 1). The landfill received a Permit to Operate on April 1, 2021. Leachate is conveyed from the landfill to a leachate tank for short-term storage. Leachate from the tank is discharged to the Buncombe County Metropolitan Sewerage District (MSD) where it comingles with other wastewater for treatment. The waste material placed throughout the life of the landfill consists of CCR, predominantly formerly ponded fly ash and bottom ash. The landfill no longer receives waste; closure was substantially complete in April 2023. 1.2 Site Geology and Hydrogeology Asheville is within the Blue Ridge physiographic province, where soil overlying the bedrock has formed from the in -place weathering of bedrock. The groundwater system at the Site is grouped into three flow zones to distinguish the interconnected groundwater system: surficial zone (primarily saprolite), transition zone (between surficial and bedrock), and bedrock (competent rock). Groundwater is usually first encountered in the surficial flow zone; however, the surficial zone and transition zone thin to the west and northwest in the area of the landfill resulting in groundwater encountered only within the bedrock zone. Groundwater enters the system from upgradient, headwaters east of the landfill, and generally flows downward to the west toward an unnamed stream, and to the northwest toward a wetland area and several unnamed streams, which converge into Powell Creek. The wetland area and streams act as groundwater discharge zones downgradient of the landfill which are classified as Class C under Title 15A, NCAC, Subchapter 02B, Surface Water and Standards (02B standards). Flow from those surface water features eventually reaches the French Broad River, which is classified as Class B surface waters under 02B standards. CCR Landfill 1119-INDUS Revision 3, September 6, 2023 Water Quality Monitoring Plan 2.0 Monitoring System Performance of the landfill -engineered base liner system and engineered cover are evaluated for control of releases to the environment based on water quality of groundwater and surface water downgradient of the landfill. Leachate is sampled from the leachate collection system to primarily provide analytical data to assist in evaluating potential water quality exceedances to determine if the landfill performance is a contributor of constituents in the environment. Sample locations and descriptions are presented in Appendix II, Table 1. 2.1 Groundwater Monitoring (NCAC 15A 13B .0601) The groundwater monitoring network is designed to yield groundwater samples representative of aquifer conditions underlying the landfill area to monitor groundwater quality in the uppermost aquifer. The groundwater monitoring network consists of water quality wells upgradient of the landfill to determine background concentrations, water quality wells downgradient of the landfill to monitor performance of the landfill -engineered base liner system, and water -level -only wells to assist with refinement of groundwater flow. The groundwater monitoring network is shown in Appendix I, Drawing 2. Drawings 3A and 3B of Appendix I identify the water quality wells in the surficial, transition, and bedrock flow zones and depict the groundwater flow direction for each flow zone. Upgradient (background) water quality wells screened in: Surficial flow zone: • ASV-CB-9 ASV-CB9-SL • ASV- LMW-1 S Downgradient water quality wells screened in: Transition flow zone: ASV-LMW-2T Water -level -only wells screened in: Transition flow zone: ASV-CB-8 • ASV-MW-13D Bedrock flow zone: • ASV-CB-9BR ASV-LMW-1 B Bedrock flow zone: ASV-LMW-2B • ASV-LMW-3B • ASV-LMW-4B Bedrock flow zone: ASV-CB-8BR • ASV-MW-13BR Monitoring well construction details are included in Appendix II, Table 2. Boring logs and well construction records are provided in Appendix III. CCR Landfill 1119-INDUS Water Quality Monitoring Plan Revision 3, September 6, 2023 2.1.1 Groundwater— Well Construction and Decommissioning Monitoring wells are constructed in accordance with NCAC 02C .0108 and guidance provided by NCDEQ (NCDEQ, 2023). A typical monitoring well construction detail is provided on Drawing 4 of Appendix I. Constructed monitoring wells are located by a North Carolina Professional Land Surveyor to within +0.1 foot on the horizontal plane and +0.01 foot vertically in reference to existing survey points and developed in accordance with NCAC 02C .0108 (q). Dedicated stainless steel bladder pumps are installed to help reduce agitation during sampling, resulting in lower sample turbidity and minimizing the risk of cross - contamination from well to well. Pump intakes are generally set within the center of each well screen. If a monitoring well no longer provides a sample representative of the quality of groundwater passing the relevant point of compliance, the SWS will be notified. The Owner or Owner's Representative will re-evaluate the groundwater monitoring network, and provide recommendations to the SWS for modifying, rehabilitating, decommissioning, or installing replacement or additional monitoring wells, as appropriate. 2.2 Surface Water Monitoring (NCAC 15A 13B .0602) The surface water monitoring network is designed to monitor the quality of jurisdictional waters. Surface water is monitored at three locations downgradient of the landfill to monitor performance of the landfill -engineered base liner system and closure system. There are no upgradient surface water monitoring locations. The surface water monitoring network is shown in Appendix I, Drawing 2. Details about the surface water monitoring network downgradient of the landfill include: • ASV-LF-SW1 is located west of the landfill in an unnamed tributary that flows to the French Broad River, which is classified as Class B surface waters. The stream is a groundwater discharge zone approximately 100 feet side -gradient of the landfill. The location is monitored for water quality in conjunction with groundwater to monitor the performance of the landfill liner and closure systems. • ASV-LF-SW2 is located northwest of the landfill in Powell Creek, which is classified as a Class C surface water. The stream is a groundwater discharge zone approximately 300 feet downgradient of the landfill. The location is monitored for water quality in conjunction with groundwater to monitor the performance of the landfill liner and closure systems. • ASV-LF-SW3 is located north of the landfill in Powell Creek, upgradient of sampling location ASV-LF-SW2. The stream is a groundwater discharge zone approximately 120 feet downgradient of the landfill. The location is monitored for water quality in conjunction with groundwater to monitor the performance of the landfill liner and closure systems. CCR Landfill 1119-INDUS Revision 3, September 6, 2023 Water Quality Monitoring Plan 2.3 Engineered Drain Outlet Monitoring The mechanically stabilized earthen (MSE) berm is constructed with an engineered drain in the northwest area of the landfill to capture groundwater seepage from beneath the landfill - engineered base liner. The engineered drain outlet sample location ASV-DP-4 is shown in Appendix I, Drawing 2. 2.4 Leachate Monitoring One leachate sample location, ASV-LCS-1, representing leachate from the entire landfill, is collected from an in -line sampling port along the force main conveying leachate from the landfill to the Leachate Storage Tank (Drawing 2). 3.0 Sampling and Analysis Groundwater, surface water, engineered drain outlet, and leachate will be sampled and analyzed on a semiannual basis during the life of the facility and the post -closure care period. 3.1 Groundwater — Sampling and Analysis Groundwater samples are collected in accordance with NCAC 13B .0601 and guidance provided by NCDEQ (NCDEQ, 2023). Field collection procedures, labeling, chain -of -custody (COC) documentation, and laboratory receipt are included in the Duke Energy Groundwater and Sampling Collection Procedure provided as Attachment 1 of Appendix IV. Constituents for analysis and respective analytical methods are listed in Table 3 of Appendix II. Groundwater samples will be compared to appropriate North Carolina Regulatory Standards (02L). In addition, required field parameters, including but not limited to, pH, conductivity, dissolved oxygen (DO), oxidation reduction potential (ORP), temperature, and turbidity will be measured during each sampling event. 3.1.1 Establishment of Background Eight independent groundwater samples were collected from each monitoring well prior to receipt of waste material, as specified in the Solid Waste Permit to Construct. Pre - disposal samples collected from wells were analyzed for the constituents listed in Table 3 in Appendix II. The intent of pre -disposal sampling is to collect pre -waste data to compare to post -waste analytical results more accurately. This groundwater data was submitted to the SWS in the Groundwater Monitoring Report — Baseline Sampling Events #1 through #4 (SynTerra, 2021 a). 3.2 Surface Water — Sampling and Analysis Surface water samples are only collected at each location if flowing water is observed during the sampling event. Samples are obtained using the grab sample method. Field collection procedures, labeling, COC documentation, and laboratory receipt are included in the Duke Energy Landfill Sample Collection Guidelines provided as Attachment 2 of Appendix IV. Constituents for analysis and respective analytical methods are listed in Table 3 of Appendix II. Surface water analytical results are screened to applicable Classifications and Water Quality Standards Applicable to Surface Waters and Wetlands of North Carolina as defined in 15A NCAC 0213, in -stream target values (ISTV), and the U.S. Environmental Protection Agency (USEPA) National Recommended Water Quality Criteria (NRWQC) for Aquatic Life and CCR Landfill 1119-INDUS Water Quality Monitoring Plan Revision 3, September 6, 2023 Human Health (Appendix II, Table 3). Duke Energy provides comparisons against ISTV with the qualification that an exceedance of the published value is not necessarily a violation of the water quality standard for toxicity. As stated by the USEPA, NRWQC standards do not constitute regulations, nor do they impose a legally binding requirement. Therefore, comparisons with those criteria are for information purposes only. Additional information regarding surface water standards and screening criteria are outlined below: • Several 02B standards and ISTV require sampling methods specific to acute or chronic concentrations and are not applicable to the grab sample method; however acute standards are considered more applicable to grab sampling and are included for screening purposes only. Hardness -dependent standards require sampling methods specific to acute or chronic concentrations and are not applicable to the grab sample method. Duke Energy will use a standard hardness of 25 milligrams per liter (mg/L) for screening purposes only; however, if the in -stream hardness values for a given sampling event are substantially less than or greater than 25 mg/L, the minimum in -stream hardness value will be used to calculate the hardness -dependent standard to more accurately screen analytical results. • The 02B surface water standards for chromium are based upon speciation for dissolved trivalent and hexavalent chromium. Duke energy will sample for total and dissolved total chromium. Results will be screened to the dissolved trivalent 02B standard; this standard is also a hardness dependent, acute standard and will be based on 25 mg/L hardness and used for screening purposes only. The 02B surface water standard for mercury represents a total concentration and is not for acute, chronic, or hardness -dependent concentrations. The mercury 02B standard for Class B, C, and water supply waters is 0.012 micrograms per liter (pg/L). Duke Energy will use the analytical method USEPA 245.1/SW 7470A for mercury analysis, which has a reporting limit of 0.050 fag/L and is greater than the 02B criteria of 0.012 fag/L. 3.3 Engineered Drain Outlet - Sampling and Analysis An engineered drain outlet sample is only collected if flowing water is observed during the sampling event. Samples are obtained using the grab sample method. Field collection procedures, labeling, COC documentation, and laboratory receipt are included in the Duke Energy Landfill Sample Collection Guidelines provided as Attachment 2 of Appendix IV. Analytical results from the engineered drain outlet are compared to applicable 02B surface water standards. Constituents for analysis and respective analytical methods are listed in Table 3 of Appendix II. 3.4 Leachate — Sampling and Analysis A leachate sample is collected from an inline sample port. Field collection procedures, labeling, COC documentation, and laboratory receipt are included in the Duke Energy Landfill Sample Collection Guidelines provided as Attachment 2 of Appendix IV. Constituents for analysis and respective analytical methods are listed in Table 3 of Appendix II.

Purpose 1.1 The purpose of this procedure is to provide field methods used by Duke Energy staff and contractors during the collection of groundwater measurements and samples. As such, this procedure discusses multiple sampling approaches specific to various groundwater conditions and programs. The objectives of this procedure are to ensure consistent collection of valid and representative samples that provide reproducible and reliable groundwater data to meet project/program requirements. This Standard Operating Procedure (SOP) includes proper well purging and sampling techniques designed to reduce the potential of cross -contamination during sample collection and handling. Also included are procedures for field data documentation, chain of custody records, and coordination with both site personnel and the Analytical Laboratory Components of this procedure may be incorporated into a site -specific Sampling and Analyses Plan (SAP) for each program. In addition to SAP's, site specific Groundwater Program Requirements (GPR) were developed and are maintained on a secure Corporate LAN share. Compliance to these program requirements are mandatory for field personnel and compiled on a form similar to Appendix A. Any changes made to sampling requirements are updated as necessary on these forms to ensure proper analytical methods are used, that required samples are collected, and preferred sampling methods and stabilization criteria for each program are met. 2. Preparing for The Field 2.1 Proper planning, preparation, and coordination are necessary for a successful project execution. This includes a clear understanding of sampling event objectives and developing a corresponding scope of work to meet those objectives. The sampling equipment checklist (Appendix A) was developed to aid in field organization and should be used prior to each sampling event. Depending on the site -specific project/program, additional equipment/supplies may be necessary and should be determined before the scheduled sampling event. 2.1.1 Laboratory coordination is vital to project execution. The previously prepared Chain of Custody (COC) is reviewed by the Site Lead and forwarded to the lab for review and editing (30 days prior to the event). Based on the COC, bottle kits (including spare kits) are prepared and supplied by the lab the week before the scheduled field event. 2.1.2 Coordination with site contacts should be conducted at least 30 days prior to the field event. It is important that the site is aware of the type of work to be conducted, the schedule, and personnel to be involved. Site specific orientation training is required annually of all Duke personnel prior to initiating work at Duke facilities and this should be pre -arranged with the appropriate safety personnel. Maintain daily communication with site contacts and advise them of progress. Promptly advise site contacts of any project related incidents/accidents and any issues with site access. ADMP-ENV-EVS-00100 I Rev. 006 05/2020 Page 4 of 31 Duke Energy Proprietary Business Information - Not for external distribution AUTHORIZED COPY 2.1.3 Proper care should be exercised in the scheduling of personnel and the allocation of equipment, and materials so that the planned field event can be executed safely and efficiently. Equipment and instrumentation should be inspected, cleaned, and calibrated daily with nitrile gloves (start and end of day). An example calibration and post check log is included in Appendix C. 2.1.4 Safety is always important in planning and executing a sampling event. A Pre -Job Brief (PJB) and Job Hazard Analysis (JHA) should be prepared and reviewed with the field team at the site and prior to performing any field activities. A JHA has been developed for groundwater sampling and is included as Appendix B. This JHA should be reviewed prior to each event and discussed as appropriate for site -specific conditions. Additional safety tools such as conducting a "360 Inspection" on all moving equipment prior to use and "Take a Minute" to review site conditions prior to starting work should be routinely utilized. 3. Instrument Calibration 3.1 It is important that all field instrumentation is calibrated in accordance to manufacturer specifications. The water quality meter (pH, specific conductivity, and ORP) and the turbidity meter should be calibrated in the field at the beginning and at the end of the day. A Daily Calibration Log is included as Appendix C. 4. Well Development 4.1 The drilling and installation of monitoring wells disturbs geologic materials surrounding the borehole. Well development is necessary to promote hydraulic communication between the well screen and the surrounding aquifer. Proper development also ensures the removal of fine- grained soil particles from around the screen reducing turbidity and the potential for bias in groundwater sample results. Well development should be conducted promptly after well installation but no sooner than 24 hours after grouting. Common methods of well development include over pumping, surging, bailing, and jetting. Redevelopment of wells is conducted when the desired water quality is not achieved, typically but not exclusively, with regard to turbidity. Redevelopment methods are similar to development techniques and can be conducted for several episodes until the desired water quality parameters are achieved. The following steps outline the procedure that will be used to develop or redevelop a monitoring well using the over pumping method. This method involves pumping at a rate fast enough to draw the water level as low as possible while also allowing the water level to recharge back to the initial level. This method is repeated until desired water quality is achieved. 4.1.1 Measure the static water level with a decontaminated water level meter and record in the field workbook/GMDS 4.1.2 If the well is equipped with a dedicated bladder pump, carefully pull tubing and pump up (with gloves) and set aside on a clean plastic sheet. 4.1.3 Examine the pump for any damages to seals or drainage areas. 4.1.4 Carefully place a clean submersible pump down the well with attached tubing. The pump should be placed approximately one foot from the bottom of the well. ADMP-ENV-EVS-00100 I Rev. 006 05/2020 Page 5 of 31 Duke Energy Proprietary Business Information - Not for external distribution AUTHORIZED COPY 4.1.5 Secure tubing to well casing and attach water discharge line to appropriate water quality instrument. 4.1.6 Connect the pump to a power source and begin to purge well at a moderately high flow rate. 4.1.7 Frequently check the water level and flow rate to verify that the drawdown is stabilizing. Wells with poor recharge will sometimes not be able achieve a maintained drawdown and will go dry. If this happens, development will stop and continue once the well has recharged. 4.1.8 Once an acceptable flow rate has been established and drawdown has stabilized, it is acceptable to begin recording indicator field parameters at specific intervals (usually every 3 to 5 minutes). 4.1.9 Continue purging the well until desired water quality parameters are achieved. 5. Dedicated Equipment Installation 5.1 Dedicated sampling equipment is installed in monitoring wells to improve sampling efficiency and sampling results. Dedicated sampling equipment previously installed in the well eliminates the need to introduce pumps/tubing into the well disturbing the existing well water prolonging well stabilization prior to sample collection. Thus, existing dedicated equipment reduces sampling time. Dedicated well equipment also eliminates the need to decontaminate any equipment used in multiple wells reducing the potential for cross -contamination and improving monitoring results. 5.2 Dedicated well sampling equipment includes well caps, tubing, and bladder pumps. Care must be taken during installation to properly measure and cut the tubing such that the end of the tubing (peristaltic pumps) or the bladder pumps are positioned strategically at the mid -point of the wetted screen. If the equipment is positioned too deep it could disturb sediment collected in the bottom of the well increasing turbidity and if positioned too shallow could be above static water levels during periods of depressed groundwater levels. 6. Water Level Measurements 6.1 Water level measurements will be completed prior to pump placement, groundwater sampling, or aquifer characterization activities. Some groundwater sampling events/programs require a comprehensive water level sweep of all monitoring wells within a 24-hour period. In these instances, a round of synoptic depth to water measurements will be collected prior to groundwater sampling. These contemporaneous water levels are used in the construction of potentiometric surface maps for the site. The following steps outline the procedures that will be used to collect water level measurements. 6.1.1 Describe the condition of the well (lock, pad, protective casing, general access), ambient weather conditions and other factors that could affect the final data analysis. This documentation is recorded on the Groundwater Monitoring Data Sheet (GMDS) (Appendix D). 6.1.2 An electronic water -level indicator accurate to 0.01 feet should be used to measure depth to groundwater within the monitoring well. ADMP-ENV-EVS-00100 I Rev. 006 05/2020 Page 6 of 31 Duke Energy Proprietary Business Information - Not for external distribution AUTHORIZED COPY 6.1.3 The electronic water -level indicator and tape will be decontaminated prior to initiating water level measurements and between all wells. Decontamination procedures are described in Appendix E. 6.1.4 The protective casing or flush -mounted vault cover will be unlocked/removed and the inner cap on the riser removed. Caution should be exercised while accessing these areas which often are occupied by insects (wasps/spiders). Standing water present within the protective casing/well vault above the riser should be documented and removed prior to removing the well cap. After riser cap removal, the well should be left open for up to 30 minutes to allow the static water level to equilibrate with atmospheric conditions before measuring (if vented caps are not used). 6.1.5 The probe should be checked to verify that it is operational, then slowly lowered into the well. A new pair of nitrile gloves should be worn before each water level measurement is taken. 6.1.6 Fluid level measurements will be recorded relative to a fixed reference point using an electric tape graduated in 0.01-foot intervals. The fixed reference point on the riser will consist of a V-notch or an indelible mark at the top of the riser, or if neither is present, measure to lowest side of the riser and create a reference point for future measurements. 6.1.7 Using the electronic water -level indicator, measure the distance between the reference point and the water surface within the well. The measurements will be repeated until two measurements are obtained that are within 0.01 feet. Record this information on the GMDS. 6.1.8 If the total depth of the well has not been previously measured, using the water -level indicator, measure the distance from the reference point to the bottom of the well. The measurements will be repeated until two measurements are obtained that are within 0.01 feet. Record this information on the GMDS. If the total depth of the well has been previously determined, a measurement for total depth is not necessary as disturbing bottom sediment in the well can contribute to increased turbidity. 6.1.9 The water -level indicator will be removed and decontaminated if moving to another well. 7. Groundwater Sample Collection 7.1 As stated in the Introduction, the objectives of this procedure are to ensure the collection of valid and representative groundwater samples from monitoring wells that meet project, program, and permit requirements. These objectives are not limited to sample collection, but also include procedures for the proper handling, transportation and preservation of collected samples to prevent deterioration or contamination prior to laboratory analysis. Additionally, there are several methods for groundwater sampling available. The appropriate method for an individual location/project is dependent upon the program requirements and site specific hydrogeologic conditions. NOTE: New, clean nitrile gloves shall be worn during all phases of well sampling and sample handling. ADMP-ENV-EVS-00100 I Rev. 006 05/2020 Page 7 of 31 Duke Energy Proprietary Business Information - Not for external distribution AUTHORIZED COPY 7.2 CHAIN OF CUSTODY 7.2.1 The Chain of Custody (COC) is a legal document that must be complete, accurate, and show an unbroken trail of accountability that insures the physical security of a sample. A COC must accompany each shipment of samples. Each individual sample should appear on a separate line within the COC. The original COC should accompany the sample(s) to the laboratory and the sampler should keep a copy. Chain of Custody control for all samples will consist of the following: 7.2.1.1. Sample containers will be securely placed in coolers (iced) and will remain under the supervision of project personnel until transfer of the samples to the laboratory for analysis has occurred. Ensure sufficient ice is placed in cooler to reach and maintain 40C until delivery to the laboratory. 7.2.1.2. Upon delivery to the laboratory, the laboratory director or his designee will sign the Chain of Custody control forms and formally receive the samples. The laboratory will ensure that proper refrigeration of the samples is maintained. 7.2.1.3. The Chain of Custody document contains information which may include: • Client name • Client project name • Client contact • Client address • Client phone/fax number • Sampler(s) name and signature • Signature of person involved in the chain of possession • Inclusive dates of possession • Sample identification • Sample number • Date & time of collection • Matrix • Type of container and preservative • Number of containers • Sample type - grab or composite • Analysis parameter(s)/ method • Internal temperature of shipping container upon opening in the laboratory 7.3 SAMPLE HANDLING, PACKING, AND SHIPPING Samples shall be marked, labeled, packaged, and shipped in accordance with the sections outlined below. 7.3.1 Handling: The samples will be stored in coolers for transport to the site. Collected samples will be placed on ice in the sampling coolers for pickup or transport to the laboratory for analysis. Nitrile gloves should always be worn when handling or collecting samples. ADMP-ENV-EVS-00100 I Rev. 006 05/2020 Page 8 of 31 Duke Energy Proprietary Business Information - Not for external distribution AUTHORIZED COPY 7.3.2 Sampling Labels: All sample containers will be new, laboratory cleaned and certified bottles. The bottles will be properly labeled in accordance with Appendix G for identification and will include the following information: • Project Site/ID • Sample identifier (Well ID) • Name or initials of sampler(s) • Date and time of collection • Analysis parameter(s)/method • Preservative 7.4 GROUNDWATER SAMPLING METHODS 7.4.1 There are several methods of groundwater sampling available dependent upon groundwater conditions, local and state regulatory requirements, and the goals of the sampling program. These methods include Low Flow (Low Stress), Equipment Purge, and Conventional (Multiple Volume) sampling. Based upon site conditions and/or requirements, the Site Lead/Lead Scientist/SME should select the most appropriate sampling method. 7.4.2 Prior to sample collection, the monitoring well must be properly purged. Purging is the process of removing stagnant water from the monitoring well in order to access groundwater from the surrounding aquifer for the collection of a representative sample. Indicator parameters of water being withdrawn from the well during the purging process should be monitored and recorded to confirm the presence of representative groundwater. Quantities of water should also be measured and recorded in the field workbook or on the GMDS. When purging or sampling a monitoring well, all equipment and meters introduced to the well must be clean and nitrile gloves should always be worn. Prior to purging, all equipment and sampling bottles will be placed on tables covered with new plastic sheeting or sheeting on the ground in order to prevent contamination. 7.4.2.1. Low Flow Sampling Low Flow groundwater sampling is the most commonly used and preferred method at Duke Energy for groundwater sampling. Low Flow is also known as Low Stress because the intent of this method is to minimize stress on the aquifer during the purge/sampling process. The goal of Low Flow is to withdraw representative groundwater from the surrounding aquifer while causing a minimal disturbance to the stagnant water contained within the well casing, above the screen, by stabilizing drawdown and creating laminar flow from the aquifer into the well screen. Low flow purging/sampling requires the use of a variable speed pump. Typically, adjustable -rate peristaltic, bladder, or electric submersible pumps are used. Specific pump selection is dependent upon well construction details, hydrogeologic conditions, and analytes to be tested. Low - flow purging and sampling guidance is provided below: • Low Flow Purging o Measure the static water level and record in the field workbook/GMDS. If a non -dedicated pump is used, allow time for the water level to equilibrate after pump installation. ADMP-ENV-EVS-00100 I Rev. 006 05/2020 Page 9 of 31 Duke Energy Proprietary Business Information — Not for external distribution AUTHORIZED COPY o Using well specific construction details and current water -level measurement, the pump intake is typically set to the approximate mid- point of the saturated well screen or other target sample collection depth. o If the well is equipped with a dedicated bladder pump, attach the air supply and discharge tubing to the well head. If a dedicated pump is not present, attach tubing and supporting rope (if applicable) to the pump and slowly lower the unit until the target intake depth is reached. When using a peristaltic pump, lower just the tubing to the desired depth. Record the depth to the pump intake (or tubing) in the field workbook/GMDS. o If the well has been previously sampled using low -flow purging and sampling methods, begin purging at the rate known to minimize drawdown. The goal is to induce a flow rate matching the well's recharge rate by stabilizing drawdown. Frequently check the flow rate and water level to verify that drawdown is stabilized and maintained. If results from the previous sampling event are not available, begin purging the well at the minimum pumping rate of approximately 100 milliliters per minute (mL/min). Slowly increase the pumping rate to a level that does not cause the well to drawdown more than about 0.3 feet, if possible. Never increase the pumping rate to a level in excess of 500 mL/min (approximately 0.13 gallons per minute [gpm]). Record the stabilized flow rate, drawdown, and time in the field workbook/GMDS. o Certain hydrogeologic environments will result in monitoring wells with very low yielding conditions in which stabilized drawdown is difficult to attain. Typically, in these low -permeability settings, the geologic unit being screened is composed of finer grained materials (silt and clays) or fractured rock with discrete flow channels resulting in very low hydraulic conductivities. These types of conditions may require extremely low pumping rates to maintain the static water level within the well. If the drawdown does not stabilize, which is a requirement of Low Flow purging/sampling, an alternative method of sample collection should be considered (EPA-SESD, 2017). o For wells that either have very slow recharge rates or draw down excessively at a low pumping rate, the Field Team Leader shall seek guidance from the Supervising or Lead Scientist for the selection of an appropriate alternative purging and sampling. o Once an acceptable flow rate has been established and drawdown has stabilized, it is acceptable to begin recording indicator field parameters at specific intervals (usually every 3 to 5 minutes). Indicator parameters are pH, specific conductance, turbidity, and dissolved oxygen (DO). Although not considered purge stabilization parameters, temperature and oxidation reduction potential (ORP) should be recorded during purging (EPA-SESD, 2017). Base the frequency of the measurements on the ADMP-ENV-EVS-00100 I Rev. 006 05/2020 Page 10 of 31 Duke Energy Proprietary Business Information - Not for external distribution AUTHORIZED COPY time required to completely evacuate one volume of the flow- through - cell to ensure that independent measurements are made. For example, a 500-mL cell in a system pumped at a rate of 100 mL/min is evacuated in five minutes. Typically, indicator parameters are monitored every three to five minutes and recorded in the field workbook/GMDS. The water level within the well and flow rate should also be recorded at five- minute intervals to document stable drawdown is maintained. Adjust pumping rates as needed. • Low Flow Stabilization Indicator parameters of water being withdrawn from the well during the purging process should be monitored and recorded to confirm the presence of representative groundwater. The volume of water that is withdrawn should also be measured and recorded in the field workbook or on the GMDS. o During the purging process, water quality parameters will be measured and recorded in the field workbook or on the GMDS. The purpose of monitoring field parameters is to determine water chemistry stabilization, thus confirming the presence of representative groundwater from the aquifer in preparation for sample collection. Water -quality parameters monitored to confirm groundwater stabilization include pH, specific conductance, dissolved oxygen, and turbidity. Additional field parameters to be routinely monitored, although not used for groundwater stabilization determination, include temperature and oxidation reduction potential (EPA-SESD, 2017). o Water -quality stabilization is considered accomplished when three consecutive readings of field indicator parameter measurements meet the following established criteria (EPA-SESD, 2017): ■ pH ± 0.1 standard unit ■ Specific Conductance ± 5% in µS/cm ■ DO ± 0.2 mg/L or 10% saturation o Temperature and ORP field measurements should not be used as parameters for stabilization determination, however these parameters should be measured and recorded during the purging process (EPA- SESD, 2017). o The target for turbidity is less than ten nephelometric turbidity units (NTUs), which is twice the Primary Drinking Water Standard of five NTUs. Turbid conditions with higher NTUs can bias laboratory analyses for inorganic and hydrophobic parameters. In some hydrogeologic environments, even with proper well design, construction, and development, elevated turbidity values are encountered due to natural aquifer conditions (EPA, 2002). When these conditions occur, the following guidelines shall be considered. ADMP-ENV-EVS-00100 I Rev. 006 05/2020 Page 11 of 31 Duke Energy Proprietary Business Information - Not for external distribution AUTHORIZED COPY ■ If turbidity readings are slightly above 10 NTUs, but trending downward, purging and monitoring should continue. ■ If turbidity readings are greater than 10 NTUs and have stabilized to within 10% during three successive readings or if purging has continued for more than an hour, consult the Supervisor prior to collecting the groundwater sample. • Low Flow Sampling o Record the final pump settings, water level, and volume of water removed in the field workbook/GMDS prior to sample collection. o Measure and record the indicator parameter readings prior to sample collection. Follow the recommended significant figures for each parameter listed on the GMDS. o Record comments pertinent to the appearance (color, clear, clear with flocculate, turbid, sheen, etc.) and obvious odors (such as sulfur or petroleum) associated with the water. o Always wear a new pair of nitrile gloves for each well. o Arrange and label sample bottles and ensure that preservatives are added, as required. Do not overfill pre -preserved bottles. Include a unique sample number, time and date of sampling, the initials of the sampler, and the requested analysis on the label in accordance with Appendix G. Additionally, provide information pertinent to the preservation materials or chemicals used in the sample. o Generally, maintain pumping rate used during purging for sample collection. However, when collecting samples for volatile organic compounds (VOCs), the flow rate should be reduced to 100 ml/min. Collect samples directly from pump tubing prior to the flow -through cell or via an in -line T-valve. Ensure that the sampling tubing remains filled during sampling and attempt to prevent water from descending back into the well. Minimize turbulence when filling sample containers. Fill the labeled sample bottles in the following order: ➢ Metals and Radionuclides, ➢ Other inorganic analytes, and then ➢ Other water -quality parameters (including organics). o Seal each sample and place the sample on ice in a cooler to maintain sample temperature preservation requirements. Ensure a temperature blank is placed in the cooler with samples. o Note the sample identification and sample collection time in field workbook/GMDS and on Chain -of -Custody form. o Decontaminate non -dedicated equipment when sampling is complete, in accordance with procedures outlined in the Decontamination of Equipment SOP (Appendix E). ADMP-ENV-EVS-00100 I Rev. 006 05/2020 Page 12 of 31 Duke Energy Proprietary Business Information - Not for external distribution AUTHORIZED COPY o Close and secure the well. Clean up and remove debris left from the sampling event. Be sure that Investigative Derived Waste (IDW) is properly containerized and labeled, if applicable. o Review sampling records for completeness. Add additional notes as necessary. 7.4.2.2. Equipment Purge Sampling Equipment Purge (also referred to as Minimum Purge) is an alternative purging method used primarily on monitoring wells which do not meet the stabilization criteria of Low -Flow samplings due to slow recharge conditions (Kaminski, 2013). In these situations, the static water level in the well cannot be maintained, even at reduced pumping rates during the purging process. The Equipment Purge approach is preferred in both wells that historically exhibit excessive drawdown during purging and in new wells that display an inability to maintain a consistent water level during purging. The Equipment Purge approach is preferred to the Conventional (volumetric) Purge approach, which in low yielding wells results in dewatering the well (pumping the well dry) and exposing the screened interval/filter pack to air (Kaminski, 2013). Exposure of the screened interval to air promotes oxidation which can influence the redox state in groundwater, affecting water chemistry, especially for inorganics, which constitute important sampling parameters at Duke Energy sites. The Equipment Purge method is also preferred over other Minimum -Purge and No -Purge methods, such as Passive Diffusion Bags, HydraSleeves, and Snap Samplers, which do not produce the volume of water needed to complete the analytical suite typically required for Duke Energy sites. The water level should occur within the screened interval of the monitoring well when utilizing the Equipment Purge sampling approach. Equipment set up is similar to Low -Flow purging/sampling with an appropriate pump, tubing and flow -through cell. One volume of water equivalent to the volumetric sum of the tubing, flow -through cell, and bladder (if used) should be withdrawn from the well flushing the sampling equipment. Once the single volume of water has been removed, a set of field parameters should be measured/recorded prior to sample collection. This information is recorded in the field workbook/GMDS noting the sampling method used. 7.4.2.3. Conventional Sampling The Conventional method of groundwater sampling has been removing three to five equivalent well volumes and recording water quality field parameters after each well volume is removed. This is continued for three to five well volumes to determine when stabilization occurs indicating representative groundwater. Groundwater samples are then collected after a multiple well volume purge has been conducted and indicator parameters have stabilized. It is acceptable to sample after five wells volumes have been removed even though indicator parameters have not stabilized. The Field Team Leader shall seek approval from the Supervisor before utilizing the multiple volume method instead of the ADMP-ENV-EVS-00100 I Rev. 006 05/2020 Page 13 of 31 Duke Energy Proprietary Business Information - Not for external distribution AUTHORIZED COPY low -flow method. In some cases, the permit may specify conventional well volume purging. o Purge Volume Calculation - Based on the depth -to -water (DTW) and total depth (TD) measurements, the volume of standing water in the well must be calculated using the following equation: ➢ Subtract DTW from TD to calculate the length of the standing water column (L_wc) in the well. TD-DTW=L we o Multiply the length of the standing water column by the volume calculation (gallon per linear foot of depth) based on the inner casing diameter (see example list below) to determine the total standing water volume; this represents one well volume. V w = L we X2ar2 1-inch well = 0.041 gallon per linear foot 2-inch well = 0.163 gallon per linear foot 4-inch well = 0.653 gallon per linear foot 6-inch well = 1.469 gallons per linear foot 8-inch well = 2.611 gallons per linear foot o Multiply the well volume calculated in the previous step by three and five to obtain the approximate respective total purge volume. For wells with multiple casing diameters (such as open bedrock holes), consult the drill records and calculate the volume for each segment. Take the sum of the values and multiply by three and five to determine the minimum and maximum purge volumes, respectively. o Fully document the volume calculation in the field workbook\GMDS. • Conventional Purge o Maintain reasonable pumping rates to avoid over pumping or pumping the well to dryness, if possible. If necessary, adjust pumping rates, reset pump intake depth, or extend pumping times to remove the desired volume of water. The primary objective is to avoid dewatering the well screen/filter pack. o Upon reaching the target purge water volume, measure and record the indicator parameters. Repeat this process for subsequent well volumes until parameters have stabilized over three to five well volumes. Monitor the DTW to determine if excessive drawdown is occurring. It is acceptable to remove only the available well volume for subsequent readings if drawdown has changed the equivalent well volume. Do not allow the water contained in the pump tubing to drain back into the well when the pump is turned off. Use an inline check valve or similar device. The removal of three to five well volumes may not be practical in wells with slow recovery rates. If a well is pumped to near dryness, the well shall be allowed to recover prior to sampling. It is preferred to collect samples within ADMP-ENV-EVS-00100 I Rev. 006 05/2020 Page 14 of 31 Duke Energy Proprietary Business Information — Not for external distribution AUTHORIZED COPY two hours of purging after the well has recovered to provide enough volume for sample collection. Do not collect samples after 24 hours of purging because the water has re -stagnated within the well. If necessary, the two-hour limit may be exceeded to allow for sufficient recovery, but samples should be collected within 24 hours of purge completion. • Conventional Purge Stabilization Indicator parameters of water being withdrawn from the well during the purging process should be monitored and recorded to confirm the presence of representative groundwater. Quantities of removed water should also be measured and recorded in the field workbook or on the GMDS. o During the purging process, water quality parameters will be measured and recorded in the field workbook or on the GMDS. The purpose of monitoring field parameters is to determine water chemistry stabilization, thus confirming the presence of representative groundwater from the aquifer in preparation for sample collection. Water -quality parameters monitored to confirm groundwater stabilization include pH, specific conductance, dissolved oxygen, and turbidity. Additional field parameters to be routinely monitored, although not used for groundwater stabilization determination, include temperature and oxidation reduction potential (EPA-SESD, 2017). o Water -quality stabilization is considered accomplished when three consecutive readings of field indicator parameter measurements meet the following established criteria (EPA-SESD, 2017). pH f 0.1 standard unit Specific Conductance f 5% in µS/cm DO f 0.2 mg/L or 10% saturation o The target for turbidity is less than ten nephelometric turbidity units (NTUs), which is twice the Primary Drinking Water Standard of five NTUs. Turbid conditions with higher NTUs can bias laboratory analyses for inorganic and hydrophobic parameters. In some hydrogeologic environments, even with proper well design, construction, and development, elevated turbidity values are encountered due to natural aquifer conditions (EPA, 2002). When these conditions occur, the following guidelines shall be considered. o If turbidity readings are slightly above 10 NTUs, but trending downward, purging and monitoring should continue. o If turbidity readings are greater than 10 NTUs and have stabilized to within 10% during three successive readings, consult the Supervisor prior to collecting the groundwater sample. • Conventional Sampling ADMP-ENV-EVS-00100 I Rev. 006 05/2020 Page 15 of 31 Duke Energy Proprietary Business Information - Not for external distribution AUTHORIZED COPY o If during the purging process the water level within the well was substantially lowered to near dry conditions, allow the well to recharge to ensure that adequate volume is available for sample collection. If the well has not sufficiently recharged within two hours, consult the project manager. At a maximum, sampling should be completed within 24 hours of purging. o Record the final pump settings in the field workbook/GMDS prior to sample collection. o Measure and record the indicator parameter readings after each well volume is removed and prior to sample collection. Follow the recommended significant figures for each parameter listed on the GMDS. o Record comments pertinent to the appearance (color, clear, clear with flocculate, turbid, sheen, etc.) and obvious odors (such as sulfur odor or petroleum odor) associated with the water. o Always wear a new pair of nitrile gloves for each well. o Arrange and label necessary sample bottles and ensure that preservatives are added, as required. Include a unique sample number, time and date of sampling, the initials of the sampler, and the requested analysis on the label in accordance with Appendix G. Additionally, provide information pertinent to the preservation materials or chemicals used in the sample. o If sampling with a pump, care shall be taken to minimize purge water descending back into the well through the pump tubing. Minimize turbulence when filling sample containers. Fill the labeled sample bottles in the following order: ■ Metals and Radionuclides, ■ Other inorganic analytes, and then ■ Other water -quality parameters. o If sampling with a bailer (extremely rare), slowly lower a clean, disposable bailer through the fluid surface. Retrieve the bailer and fill the sample bottles as described above. Care shall be taken to minimize disturbing the sample during collection. o Seal each sample and place the sample on ice in a cooler to maintain sample temperature preservation requirements. Ensure a temperature blank is placed in the cooler with samples. o Note the sample identification and sample collection time in field workbook or on the Groundwater Sampling Field Sheets/GMDS. o Decontaminate non- dedicated equipment once sampling is complete, in accordance with procedures outlined in the Decontamination of Equipment SOP (Appendix E). ADMP-ENV-EVS-00100 I Rev. 006 05/2020 Page 16 of 31 Duke Energy Proprietary Business Information - Not for external distribution AUTHORIZED COPY o Close and secure the well. Clean up and remove debris left from the sampling event. Be sure that IDW is properly containerized and labeled, if applicable. o Review sampling records for completeness. Add additional notes as necessary. 7.5 FIELD QUALITY CONTROL SAMPLES 7.5.1 Field quality control involves the routine collection and analysis of QC blanks to verify that the sample collection and handling processes have not impaired the quality of the samples. 7.5.2 The quality control samples to be collected during every groundwater sampling event and their frequency are listed below: 7.5.2.1. Equipment Blank - a QC sample collected in the field by capturing deionized water which is poured over or through a piece of sampling/purge equipment that has been decontaminated. The equipment blank is prepared like the actual samples and returned to the laboratory for identical analysis. An equipment blank is used to determine if certain field sampling or cleaning procedures may potentially result in cross -contamination of site samples or if atmospheric contamination has occurred. One equipment blank sample will be prepared per sampling event or per 20 groundwater samples, whichever is more frequent. 7.5.2.2. Field Blank - a QC sample prepared in the field of certified clean organic -free water, which is poured into the appropriate sample containers onsite and returned to the laboratory for analysis. A field blank is used to determine potential atmospheric contamination of the samples. One field blank sample will be prepared per sampling event or per 20 groundwater samples, whichever is more frequent. 7.5.2.3. Sample Duplicate — a QC sample collected simultaneously with a standard groundwater sample from the same sampling location under identical conditions for the same analytical parameters but placed into separate sample containers. Each duplicate should be assigned its own sample number so that it will be blind to the laboratory. A duplicate sample is treated independently of its counterpart to enable assessment of the laboratory performance by comparison of the results. One duplicate sample will be prepared per sampling event or per 20 groundwater samples, whichever is more frequent 7.5.2.4. Temperature Blank — also known as Temperature Indicator (it is not really a blank) is small container of clean water that is placed in the cooler with the sample bottle kits for transport back to the laboratory after sample collection. Upon arrival at the laboratory, the temperature is measured. The Temperature Blank is not actually analyzed for the presence of contaminants. 7.5.3 Unless otherwise stated it is assumed that the QC have matching parameters to the samples which they are qualifying. The exception to this case is the field blank, which does not require TDS or filtered parameter bottles. This exception is true even if a TDS or filtered parameter bottle was taken for the sample that the field blank is qualifying. ADMP-ENV-EVS-00100 I Rev. 006 05/2020 Page 17 of 31 Duke Energy Proprietary Business Information - Not for external distribution AUTHORIZED COPY 7.6 FIELD DOCUMENTATION 7.6.1 Daily field activities shall be recorded and maintained by the Field Team Leader. Recorded activities shall be entered in the field workbook or on the Groundwater Sampling Field Sheets placed into a field Logbook to include the following information for each well: • Well identification number • Well depth • Static water level depth • Presence of immiscible layers (yes — no) • Estimated well yield, if known • Purge volume and purge pumping rate • Time well purge began and ended • Well evacuation procedure and equipment • Field analysis data • Climatic conditions including air temperature • Field observations on sampling event • Well location • Name of collector(s) • Date and time of sample collection • Sampling procedure • Sampling equipment • Types of sample containers used and sample identification numbers • Preservative used 7.6.2 The Field Team Leader shall review the recorded field entries for completeness and accuracy. The Field Team Leader is responsible for completion of the required data collection forms. At the end of each sampling event, complete a Post Sampling Well Condition Report (Appendix F), noting all challenges encountered on site. Use consistent, proper nomenclature for all field documentation of sample collection (Appendix G). 7.7 DECONTAMINATION AND WASTE MANAGEMENT 7.7.1 Sampling equipment decontamination shall be performed in a manner consistent with the Decontamination of Equipment SOP (Appendix E). Decontamination procedures shall be documented in the field Logbook. IDW produced during sampling or decontamination shall be managed in accordance with State and Station -specific rules for disposal of wastes. 8. References 8.1 U.S. EPA.

The principal purpose of a sampling and analysis program is to provide data that accurately reflect the quality of the media being investigated which begins with assurance that the composition of field samples remains unaltered before laboratory analysis. This Guideline provides information pertaining to preparation for, and field collection of, a sample. 1.2 Sampling General Requirements In addition to the information provided in this Guideline, all personnel collecting samples from a Site will: • be knowledgeable of general field collection procedures including operation of equipment to be utilized, preservatives, and storage temperature requirements, and familiar with this sampling procedure; • wear personal protective equipment (PPE) required by the Site or based on field conditions (may include a high visibility vest, hard hat, eye protection, gloves, and protective footwear); • be familiar with preservatives and/or storage temperatures required for the parameters to be analyzed; • confirm that receiving laboratory is aware of, and prepared to, accept the samples prior to mobilizing for field collection; • use new, clean, non -powdered latex or nitrile gloves at each sample collection location; • checked all equipment to ensure that it is in working order and if necessary, calibrated; • decontaminate reusable sampling equipment prior to collection of a sample; • record detailed field notes in a logbook or dedicated field form to include sample information (e.g. site name, time and date sample was collected, sample code, personnel, weather etc.), and; • document the chain of custody for each sample collected. Samples will be: • collected in certified pre -clean containers appropriate for the laboratory analyte which are labeled in accordance with Section 2.0, and supplied or recommended by the laboratory performing the analysis, filled to the brim to avoid the inclusion of air in the sample, unless there is a 'fill -to' mark (typically in pre -preserved bottles); Duke Energy Sample Collection Guideline Revision 3, July 26, 2023 • collected at locations identified in the Monitoring Plan unless an alternate location is authorized by Waste and Groundwater Programs Subject Matter Expert (SME) for the Site; documented as "Insufficient Flow" and not sampled if a location is experiencing a low flow condition that would preclude collection without entrainment of sediment, and; • stored in iced coolers, out of direct sunlight and delivered to the laboratory with minimum delay; ideally on the same day and preferably within 24 hours of sampling. 2.0 Labeling, Documentation, and Records 2.1 Sample Container Labeling 2.1.1 Prior to field mobilization Field sample containers should be labeled and organized prior to mobilization for field collection unless an emergent event precludes the ability to pre -label containers. 2.1.2 At sample collection location As samples are collected, field personnel record the date and time of collection and initials of sampler on the container label and records that information on the Monitoring Data Sheet and the Chain -of -Custody Record and Analysis Request Form (example included as an attachment to this Guideline). 2.2 Field Documentation Field documentation for each sample is recorded on the Field Monitoring Data Sheets, Field Sampling Calibration Form, and Chain -of -Custody Record and Analysis Request Form (COC Record). These sheets are arranged in sequential order and filed by project and date. Notations are made during field collection to document the following information: • identification of location; • date and time of collection; • collection method; • types of containers used; • identification of Quality Control (QC) samples (if applicable); • preservative(s) used; • parameters for analysis; • field analysis data and methods; Duke Energy Revision 3, July 26, 2023 Sample Collection Guideline • field observations during sampling event • name(s) of sample collectors(s), and; • climatic conditions including an estimate of air temperature. 2.3 Chain -of -Custody Record The COC Record 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 COC Record includes the following information: • sample identification number; • signature of collector; • date and time of collection; • sample type; • identification of location; • number of containers; • parameters requested for analysis; • preservative(s) used; • signature of all persons involved in the chain of possession, and; • inclusive dates of possession. 3.0 Sample Collection 3.1 Grab Sample Method The Grab Sample Method is simple and effective for a homogeneous sample matrix. The use of unpreserved sample containers for direct grab sampling is encouraged since the same container can be submitted for laboratory analysis after appropriate preservation. This procedure reduces sample handling and eliminates potential contamination from other sources. Sample containers with premeasured amounts of preservative shall not be used to collect field samples using this method. A clean, unpreserved sample container will be used to collect the sample and transfer the sample to the appropriate container with premeasured preservation (see Section 3.2). Sampling personnel will use the container provided or recommended by the laboratory for collecting samples that will be analyzed for volatile organic compounds (VOCs), as applicable. General steps field collection using the Grab Sample Method are: 1. Slowly submerge the container opening, neck first, into the sample media. Duke Energy Sample Collection Guideline Revision 3, July 26, 2023 2. Invert the bottle so the neck is upright and pointing towards the direction of flow (if applicable). Allow media to flow slowly into the container until filled. 3. Return the filled container quickly to the surface. 4. Pour out a few mL of sample away from and downstream of the sampling location. This procedure allows for the addition of preservatives and sample expansion. Do not use this step for volatile organics or other analytes where headspace is not allowed in the sample container, as applicable. 5. add preservatives (if applicable), securely cap container, label, and complete field notes. If sample containers are attached to a pole via a clamp, submerge the container and follow steps 3 — 5 but omit steps 1 and 2. 3.2 Unpreserved Container or Intermediate Vessel If the sample cannot be collected directly into the sample container (e.g.: Grab Sample Method) to be submitted to the laboratory, or if the laboratory provides pre - preserved sample containers, use an unpreserved, unused or decontaminated sample container or a decontaminated intermediate vessel (e.g., beakers, buckets or dippers) to collect the sample. Vessels must be constructed appropriately, including any poles or extension arms used to access the sample location. General processes for field collection using an intermediate vessel or container are: • Rinse the intermediate vessel with ample amounts of media prior to collecting the first sample. • Use an intermediate vessel or unpreserved container collect the sample as outlined in the Grab Sample Method, Section 3.1. • Use a pole mounted intermediate vessel or unpreserved container of appropriate construction to sample at unsafe distances collect the sample as outlined in the Grab Sample Method, Section 3.1. 3.3 Peristaltic Pump and Tubing This technique is not acceptable for VOCs. Extractable organics can be collected through a peristaltic pump if flexible interior -wall Teflon, polyethylene or PP tubing is used in the pump head. The most portable pump for this technique is a 12-volt peristaltic pump. Use appropriately precleaned, silicone tubing in the pump head and attach polyethylene, Tygon, etc. tubing to the pump to fill the sample container. 4.0 Custody and Laboratory Receipt 4.1 Custody of Sample For the purpose of this Guideline, a sample is considered in custody if it is: • in actual possession of the responsible person; Duke Energy Revision 3, July 26, 2023 Sample Collection Guideline • in view, after being in physical possession, or; • 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 sampling personnel throughout the duration of field collection. At the end of each day and prior to the transfer of the samples the COC Record information is completed for each sample. Upon transfer of sample custody from sampling personnel to a currier or receiving laboratory, the COC Record is: signed by sampling personnel, including date and time. If a currier is used for transporting the sample, the COC Record is: signed by the currier accepting the sample for transport, including date and time. Upon arrival at the receiving laboratory the COC Record is: signed and dated by the designee immediately following receipt by the laboratory. 4.2 Laboratory Receipt The laboratory maintains a sample -tracking record that follows the sample through each stage of processing. Sample tracking records maintain the date of sample extraction or preparation, and analysis. The sample tracking records are used to verify compliance with holding time limits during data validation and reviewed in laboratory audits. 5.0 References Environmental Protection Agency 2003.

This Plan provides information pertaining to analytical procedures, quality assurance and quality control program, and validation. 2.0 Custody and Laboratory Receipt 2.1 Laboratory Receipt The laboratory maintains a sample -tracking record that follows the sample through each stage of processing. Sample tracking records maintain the date of sample extraction or preparation, and analysis. The sample tracking records are used to verify compliance with holding time limits during data validation and reviewed in laboratory audits. 3.0 Analytical Procedures The main analytical laboratory used in this program is the Duke Energy Central Laboratory Services: NC Wastewater (#248) Certification. Vendor laboratories that meet EPA and NC certification requirements may be used for analyses with approval by Duke Energy. The analytical procedures used for this Plan are listed in Table 1. The laboratory must report any detection of any constituent (as revised in the October 27, 2006, NCDEQ Division memorandum and February 23, 2007, addendum). The laboratory certificates -of -analyses will, at a minimum, include: Narrative: The narrative will include a brief description of the sample group (number and type of samples, field and associated lab sample identification numbers, preparation and analytical methods used). The data reviewer will also include a statement that describes any method deviations or other QA/QC issues associated with that data that had the potential of affecting the usability of the data. This includes, but is not limited to: test method deviation(s), holding time violations, out -of -control incidents occurring during the processing of QC or field samples and corrective actions taken, and repeated analyses and reasons for the reanalysis (including, for example, contamination, failing surrogate recoveries, matrix effects, or dilutions). The narrative will be signed by the laboratory director or authorized laboratory representative, signifying that all statements are true to the best of the reviewer's knowledge, and that the data meet the data quality objectives as described in this Plan (except as noted). One narrative is required for each sample group. • Original Chain -of -Custody (COC) form; Page 3 of 6 • The laboratory will list all analytes for which the samples were analyzed; • Dilution factors with a narrative of the sample results, including the reasons for the dilution (if any); • Blank Data: If organic analyses is required, the laboratory will report the results of any method blanks, reagent blanks, trip blanks, field blanks, and any other blanks associated with the sample group. For inorganic analyses, the laboratory will provide the results of any preparation or initial calibration blanks associated with the sample group, and; • QC Summary: The laboratory will provide summary forms detailing laboratory QC sample results, which include individual recoveries and relative percent differences (if appropriate) for the following Quality Assurance (QA)/QC criteria: surrogates, MS analyses, MSD analyses, laboratory control samples, and sample duplicate analyses. QC control limits will also be reported; if any QC limits are exceeded, a flag or footnote will be placed to indicate the affected samples. Additional QA data and/or other pertinent data may be reported as requested. 4.0 Quality Assurance and Quality Control Program Each participating laboratory shall maintain a Quality Assurance Plan that describes the ability of the laboratory to produce acceptable quality data using the specified methods. QC checks used by the laboratory for sampling procedures and laboratory analyses are conducted for each sampling event. These QC checks consist of the preparation and submittal of field blanks, trip (travel) blanks, and/or field replicates for analysis of each of the parameters at frequencies described in the laboratory(s) procedures manuals. QC checks used by the Duke Energy laboratory for sampling procedures and laboratory analyses are conducted for each sampling event. These QC checks consist of the preparation and submittal of field blanks, trip (travel) blanks, and/or field replicates for analysis of each of the parameters at frequencies described in the laboratory(s) procedures manuals. The field QC blanks and replicates that may be included as QC checks are described below. The specific type and number of blanks used as listed below may vary depending on the sampling event and will be determined by the Duke Energy field sampling personnel: 4.1 Field Blanks • 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. Field blanks are typically utilized for each sampling event. The field blanks are typically analyzed for major anions and cations and metals. 4.2 Trip Blanks Page 4 of 6 Trip Blanks: If any samples are being analyzed for volatile organic compounds, a trip blank is required. A trip blank is a sample container filled with organic -free water in the laboratory that travels unopened with the sample bottles. The trip blank is returned to the laboratory with the field samples and analyzed along with the field samples for parameters of interest. 4.3 Field Replicates Field Replicates: A field replicate is a duplicate sample prepared at the sampling locations from equal portions of the 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. 5.0 Validation 5.1 Validation of Field Data Package The field data package includes the field records and measurements developed by the sampling team personnel. The field data package validation will be performed by Duke Energy personnel. The procedure for validation consists of the following: • a review of field data contained on the Monitoring Data Sheets for completeness; • verification that equipment blanks, field blanks, and trip blanks (if required) were properly prepared, identified, and analyzed; • a check of the Field Sampling Calibration Form for equipment calibration and instrument conditions, and; • a review of the COC Record for proper completion, signatures of field personnel and the laboratory sample custodian, dates and times, and for verification that the correct analyses were specified. 5.2 Validation of Laboratory Data The laboratory will perform a validation review of the submitted samples and analytical results to confirm that the laboratory QA/QC requirements are acceptable. Analytical results are managed in EQuIS. The EQuIS Data Qualification Module (DQM) performs the data verification/validation and creates an electronic data deliverable (EDD) file.
