Introduction On behalf of Products (SE) Pipe Line Corporation (PPL), this 2024 Annual Monitoring Report presents the results of annual groundwater monitoring from March 19 through March 20, 2024 and quarterly monitoring for light nonaqueous phase liquid (LNAPL) at PPL’s Greensboro Bulk Petroleum Breakout Facility (Breakout Facility) and the Tank #155 area in Greensboro, North Carolina (Figure 1). This report is intended to fulfill the monitoring requirements for the site outlined in the approved Corrective Action Plan (CAP) dated April 1994 (CH2M1, 1994), the CAP Addendum dated October 1997 (CH2M, 1997), and the Tank #155 CAP dated May 27, 2005 (CH2M, 2005). The purpose of the periodic groundwater monitoring activities is to evaluate the effectiveness of past corrective actions and assess the effects of natural attenuation on the residual dissolved petroleum hydrocarbons. 1.1 Scope of Work The following sections detail the scope of work conducted during the monitoring period. 1.1.1 Annual Groundwater Monitoring In accordance with the CAPs, there are two monitoring programs for the Greensboro Bulk Petroleum Breakout Facility: (1) the Breakout Facility, and (2) Tank #155. Table 1 provides a summary of the current monitoring programs for both areas. Table 1. Summary of Groundwater Monitoring Programs Products (SE) Pipe Line Corporation Breakout Facility, Greensboro, North Carolina Monitoring Program Annual Monitoring Locations Target Analytes Breakout Facility PMW-1, PMW-3, PMW-82, PMW-9, PMW-102, PMW-11, PMW-212, PMW-22, SMW-1R3, SMW-3, SMW-4, SMW-5, SMW-11, SMW-12, SMW-14, SMW-15, SMW-16, and SMW-16A Benzene, toluene, ethylbenzene, and xylenes (BTEX); methyl tertiary butyl ether (MTBE); and di-isopropyl ether (IPE) Tank #155 PMW-82, PMW-102, PMW-12, PMW-212, PMW-23, PMW-24, PMW-25, PMW-26, PMW-27, PMW-29, PMW-30, PMW-31, PMW-324, PMW-335, and PMW-345 BTEX, MTBE, IPE, 1,2-dibromoethane (EDB), and 1,2-dichloroethane (1,2-DCA) 1 CH2M HILL (CH2M) was acquired by Jacobs Engineering Group Inc. (Jacobs) in December 2017. CH2M is now part of Jacobs. 2 PMW-8, PMW-10, and PMW-21 were originally installed as sentinel wells downgradient from the Breakout Facility release (predominantly BTEX); however, the subsequent Tank #155 release (predominantly MTBE) impacted PMW-8 and PMW-21 and required installation of a new sentinel well (PMW-23). Consequently, PMW-8 and PMW-23 are now solely associated with the Tank #155 release. PMW-10 continues to serve as a downgradient sentinel well from the Breakout Facility release, but also an upgradient well for the Tank #155 release. 3 In November 2022, SMW-1 was abandoned and replaced by monitoring well SMW-1R. 4 With NCDEQ approval, monitoring wells PMW-7 and PMW-28 were removed from the Tank #155 groundwater monitoring program in 2015. 5 In accordance with NCDEQ’s request for additional investigation of the downgradient extent of the Tank #155 release, two monitoring wells (PMW-33 and PMW-34) were installed on the adjacent property owned by Carolina Thomas in 2022. 2024 Annual Monitoring Report FES0601221613RAL 2 1.1.2 Quarterly LNAPL Gauging and Recovery Eight wells, PMW-2, PMW-16, PMW-17, PMW-21, SB-8, SMW-2, SMW-2B, and SMW-6B, are gauged quarterly to monitor the presence of LNAPL and guide product recovery activities. 1.2 Regulatory Status The Site is regulated by North Carolina Department of Environmental Quality’s (NCDEQ)’s Division of Waste Management, Underground Storage Tank (UST) Section, in accordance with the UST Section, Corrective Action Guidelines, Petroleum And Hazardous Substance UST Releases, Petroleum Non-UST Releases (NCDEQ, 2021a) along with the Guilford County Department of Health and Human Services. The primary cleanup goals are the North Carolina Groundwater Quality Standards (15A NCAC 2L Groundwater Quality Standards [2L Standards]). The releases regulated under Incident Nos. 3367, 10558, and 87158 are currently assigned the Site Risk Classification/Priority Ranking of Intermediate, based on the historical presence of LNAPL. 2024 Annual Monitoring Report FES0601221613RAL 3 2. Field Activities The annual monitoring event for 2024 was performed from March 19 to March 20, 2024, and included the following:  Measurement of liquid levels and total well depths in 55 wells  Collection of groundwater samples from 28 monitoring wells  Replacement of oil-absorbent socks in 8 wells 2.1 Groundwater Elevation and LNAPL Measurements Sitewide groundwater elevations and LNAPL measurements were collected from 55 onsite monitoring wells before sampling began using an oil/water interface probe with verification of presence/absence using product reactive paste. PMW-21 was damaged due to nearby construction activities and depth to water level could not be measured. LNAPL was detected in one well (1.48 feet in PMW-1) during the annual monitoring event. LNAPL recovery activities at PMW-1 are discussed in Section 3.3. Table 2 presents groundwater elevations and LNAPL measurements for both the Breakout Facility wells and the Tank #155 wells. Quarterly LNAPL gauging is also conducted in March, June, September, and December. Fourteen monitoring wells that historically contained LNAPL are gauged and monitored for LNAPL (PMW-2, PMW-14, PMW-15, PMW-16, PMW 17, PMW-21, SMW-2, SMW-2B, SMW-6, SMW-6B, SMW-9, SMW-9B, SMW-13, and SB-8) (Table 3). Measurable LNAPL was not detected in any of these wells during this reporting period. In addition to gauging these quarterly events also include maintaining the oil-absorbent socks. 2.2 Groundwater Sampling Groundwater samples were collected from 28 monitoring wells (PMW-3, PMW-8, PMW-9, PMW-10, PMW-11, PMW-12, PMW-22, PMW-23, PMW-24, PMW-25, PMW-26, PMW-27, PMW-29, PMW-30, PMW-31, PMW-32, PMW-33, PMW-34, SWM-1R, SMW-3, SMW-4, SMW-5, SMW-11, SMW-12, SMW-14, SMW-15, SMW-16, and SMW-16A) in March 2024. A sample could not be collected from PMW-1 due to the presence of LNAPL and PMW-21 was damaged and inaccessible. Prior to sample collection, groundwater elevations at each monitoring well were measured and a new HydraSleeve was placed in the monitoring wells where samples would be retrieved, with the exception of PMW-33 and PMW-34 which were sampled using low-flow methods. The bottom of the HydraSleeve was placed on or just above the bottom of the well, and the top of the HydraSleeve was placed as close to the bottom of the well screen as possible. Following retrieval, the contents of the HydraSleeves were immediately transferred to appropriate bottle ware and placed on ice pending shipment to the laboratory. Low-flow techniques consisted of purging using a peristaltic pump with new polyethylene tubing prior to sample collection. Water quality parameters (pH, conductivity, turbidity, DO, temperature, and ORP) were measured and recorded during the purging process using a calibrated water quality meter. Purging was considered complete when three consecutive readings of pH were within 0.1 standard unit, conductivity readings were within 10 percent of each other, turbidity readings were within 10 percent of each other or fewer than 10 nephelometric turbidity units, and if drawdown of the water column was less than approximately 5 percent of the water column. When low-flow techniques were not possible (due to greater than 5 percent drawdown of the water column), groundwater samples were collected once three well volumes were removed, or the well was purged dry, whichever occurred first. Purged water was disposed of on the ground surface in the vicinity of each monitoring well location. 2024 Annual Monitoring Report FES0601221613RAL 4 Table 4 provides a summary of the target analytes and the associated analytical methods for each well sampled. Samples were shipped on ice to North Carolina certified laboratory, Eurofins TestAmerica, under chain-of- custody control. The chain-of-custody forms are included with the analytical data packages in Appendix A. 2024 Annual Monitoring Report FES0601221613RAL 5 3. Annual Monitoring Results 3.1 Groundwater Hydrology A potentiometric surface map depicting groundwater elevations measured in March 2024 is shown on Figure 2. Shallow groundwater generally flows from north to south with a minor westerly component, which is generally consistent with historical observations. The average elevation of the water table in 2024 was approximately 0.33 foot higher than in 2023. The nearby Greensboro Piedmont Triad International Airport received approximately 45.82 inches of precipitation in 2023 (NWS, 2024), which is approximately 8 percent more than the 1981-2010 average for this location (NOAA, 2022). Figure 3 depicts groundwater elevation trends since March 2006 using data available from SMW-11, PMW-22, and PMW-23. 3.2 Groundwater Monitoring Results The following sections discuss the findings of the monitoring activities at the Breakout Facility and Tank #155 releases sites. Benzene and MTBE distributions are illustrated on Figures 4 and 5. 3.2.1 Breakout Facility Analytical results from the Breakout Facility groundwater samples collected during the March 2024 monitoring event are presented in Table 56. Historical analytical data, including data from the most recent event, are summarized in Appendix B. BTEX constituents were detected in 2 of the 14 samples, with only benzene exceeding the NC 2L Standard of 1 microgram per liter (µg/L). Concentrations of benzene ranged from 2.94 µg/L (SMW-16A) to 147 µg/L (PMW-22). The benzene concentration in PMW-22 decreased from 173 µg/L in March 2023 to 147 µg/L in March 2024. The benzene concentration in SMW-16A decreased from 4.98 µg/L in March 2023 to 2.94 µg/L in March 2024. Figure 4 illustrates the distribution of benzene in groundwater during the March 2024 monitoring event. MTBE and IPE were detected in 1 of 14 samples (SMW-16A) but did not exceed their respective NC 2L Standards. Figures 6 through 8 present contaminant trends in PMW-1, PMW-22, and SMW-16A for benzene, ethylbenzene, total BTEX, and MTBE, respectively. No new data was available for Figure 6 due to the presence of LNAPL in PMW-1. Figure 9 presents the benzene concentration trends in monitoring wells PMW-1, PMW-21, PMW-22, SMW-16, and SMW-16A. Overall, contaminant concentrations continue to decrease throughout the Breakout Facility. 6 PMW-8, PMW-10, and PMW-21 (destroyed in 2023) were originally installed as sentinel wells hydraulically downgradient from the Breakout Facility release, which consisted predominantly of BTEX constituents; however, the subsequent Tank #155 release consisted of predominantly MTBE and impacted groundwater near PMW-8 and PMW-21 requiring installation of a new sentinel well further downgradient (PMW-23). Consequently, the detections reported for PMW-8 are now presented solely in the context of the Tank #155 release (Table 6). PMW-10 continues to serve as a downgradient sentinel well from the Breakout Facility release, but also as an upgradient well for the Tank #155 release (Tables 5 and 6). 2024 Annual Monitoring Report FES0601221613RAL 6 3.2.2 Tank #155 Analytical results from the Tank #155 groundwater samples collected during the March 2024 monitoring event are presented in Table 6. Table 7 summarizes the water quality parameters following purging prior to sample collection. Figures 4 and 5 illustrate the distribution of benzene and MTBE during the March 2024 monitoring event, respectively. Historical analytical data, including data from the most recent event, are summarized in Appendix B. Due to damage to the well casing PMW-21 was inaccessible. BTEX constituents were detected in 1 of the 14 samples (PMW-30), with only benzene exceeding the NC 2L Standard. MTBE was detected in 8 of the 14 samples, with 7 samples exceeding the NC 2L Standard of 20 µg/L. The concentration detected at PMW-8 increased from 198 µg/L in March 2023 to 3,880 µg/L in March 2024, but remained below the historical maximum concentration of 6,770 µg/L detected in March 2017. IPE was detected in 8 of the 14 samples, with 5 samples exceeding the NC 2L Standard of 70 µg/L. IPE in PMW-25 has increased from 350 µg/L in March 2023 to 521 µg/L in March 2024. Concentrations of IPE generally show a stable trend, with recent concentrations below historical maximums (Appendix B). 1,2-DCA was detected and exceeded the 2L Standard of 0.4 µg/L in 4 of 14 samples (PMW-25, PMW-31, PMW-32, and PMW-33). Concentrations of 1,2-DCA generally show a stable trend, with recent concentrations below historical maximums (Appendix B). 3.3 Product Recovery Since product recovery efforts began in 1994 over 3,400 gallons of LNAPL have been removed. Heavily weathered LNAPL was measured during the most recent sampling event in PMW-1 at a thickness of 1.48 feet. A sample of the LNAPL was collected and shipped to Alpha Analytical in Mansfield, Massachusetts for Whole Oil Analysis by Method 8015. PPL provided the laboratory report to Environmental Standards for forensic analysis. The LNAPL was determined to be primarily highly degraded diesel range product, with a little moderately degraded gasoline range product. Recovery and gauging data for PMW-1 is included in Table 8, and Table 3 summarizes LNAPL gauging and recovery data from 2009 to present utilizing oil absorbents, including the recent four operation and maintenance (O&M) events conducted during the monitoring period. Moving forward PMW-1 will be incorporated into the quarterly LNAPL gauging program. As a precautionary measure, oil-absorbent socks are currently installed in eight wells: SMW-2, SMW-2B, SMW-6B, PMW-2, PMW-16, PMW-17, SB-8, and PMW-1. During March 2024 O&M activities, PMW-2 could not be located due to gravel over the well, therefore, the sock could not be changed. 2024 Annual Monitoring Report FES0601221613RAL 7 4. Conclusions and Path Forward This section presents the conclusions and path forward based upon the results of the 2023-2024 groundwater monitoring period and historical trend data. The next annual monitoring report will be submitted in June 2025.  LNAPL was detected during this reporting period for the first time since March 2018: - Degraded LNAPL consisting of diesel and gasoline was measured in PMW-1 during the annual monitoring event. - Following several LNAPL recovery events no further product accumulation was observed. An oil- absorbent sock is currently installed in PMW-1 and will be monitored quarterly moving forward.  In the Breakout Facility: - Only benzene exceeded the 2L Standards with the highest concentration of benzene detected at PMW-22 (147 µg/L) which is consistent with the overall decreasing trend since the historical high concentration (958 µg/L) detected in October 2001. - Continued annual monitoring of the existing monitoring well network is appropriate.  In the Tank #155 area: - The installation of offsite monitoring wells PMW-33 and PMW-34 provided further refinement of the downgradient extent of the MTBE plume originating from Tank #155. The concentration of MTBE detected in PMW-33 (24.4 µg/L) slightly exceeded the 2L Standard of 20 µg/L and indicates the approximate downgradient extent of plume migration. - Benzene, MTBE, IPE, and 1,2-DCA exceed their respective 2L Standards in one or more wells. MTBE was most frequently detected and also most frequently exceeded its 2L Standard. - Continued annual monitoring of the existing monitoring well network is appropriate. 2024 Annual Monitoring Report FES0601221613RAL 8 5.

Introduction The purpose of this memorandum is to present the results of the data validation process for the groundwater samples collected at the PPL Greensboro Station Site. The samples were collected in March 2024. Samples were submitted to Eurofins Savannah in Savannah, Georgia for the following analyses: • SW8260D Volatile Organic Compounds (VOCs) These data were validated for compliance with the analytical method requirements. This process included a review of these data to assess the accuracy, precision, and completeness based upon procedures described in guidance documents such as the Environmental Protection Agency (EPA) National Functional Guidelines for Organic Data Review (EPA 2020). The Quality assurance/quality control (QA/QC) summary forms and data reports were reviewed, and the resulting findings are documented within each subsection that follows. During the data validation, if QA/QC parameters were not within the acceptance limits, associated sample results were appended with a primary qualifying flag that indicated a possible anomaly with these data. The qualifying flags originated during the data review and validation processes. This qualification also included the use of secondary sub-qualifier flags. The secondary qualifiers provide the reasoning behind the assignment of a qualifier to these data. The definitions of the primary qualifiers are presented below. 2. Validation Flag Definitions The following primary qualifiers were used to qualify the data: • [=]: Detected. The analyte was analyzed for and detected at the concentration shown. • [J]: Estimated. The analyte was present, but the reported value may not be accurate or precise. • [U]: Undetected. The analyte was analyzed for but not detected above the method detection limit. Data Validation Summary – • [UJ]: Detection limit estimated. The analyte was analyzed for but qualified as not detected; the detection limit is estimated. • [R]: Rejected. The data are not useable. • [X]: Excluded. Data were not used due to another value being more appropriate. 3. Quality Control Measures The following list represents the QA/QC measures that were reviewed during the data quality evaluation procedure: • Holding Times – The holding times are evaluated to verify that samples were extracted and analyzed within holding times. • Blank Samples – Method blank, equipment blank, and trip blank samples were provided for this project. Blank samples enable the reviewer to determine if an analyte may be attributed to sampling or laboratory procedures, rather than environmental contamination from site activities. • Surrogate Recoveries – Surrogate Compounds are added to each sample and the recoveries are used to monitor lab performance and possible matrix interference. • Laboratory Control Sample (LCS) – These samples are a "controlled matrix," laboratory reagent water, in which target compounds have been added prior to extraction/analysis. The recoveries serve as a monitor of the overall performance of each step during the analysis, including sample preparation. • Matrix Spike/Matrix Spike Duplicate (MS/MSD) Samples – Spike recovery is used to evaluate potential matrix interferences, as well as accuracy. Precision information is also determined by calculating the reproducibility between the recoveries of each spiked parameter. • Field Duplicate Samples – These samples are collected to determine precision between a native and its duplicate. This information can only be determined when target compounds are detected. 4. Quality Control Review The QA/QC parameters for all samples were within acceptable control limits with the exceptions listed below. A brief overview of the data evaluation follows: 4.1 Holding Time All holding times were met. 4.2 Field Duplicate Precision Duplicate field samples were collected and submitted to the laboratory for analysis. There are two conditions under which the native and field duplicate are deemed outside acceptance criteria. For condition one, if a result for the native and field duplicate are less than five times the reporting limit, the two results must be within one times the reporting limit to meet acceptance criteria. In condition two, if the result is greater than five times the reporting limit, the two results must agree to within 20 percent relative percent difference to meet acceptance criteria. All precision criteria were met. 4.3 Recoveries - Surrogate, MS/MSD and LCS/LCSD All acceptance criteria were met. Data Validation Summary – Products (SE) Pipeline ( 4.4 Analytical Blanks No target analytes were detected in the analytical blanks. 4.5 Linear Range Ethylbenzene in sample PMW-22 exceeded linear calibration range. The laboratory did not run another dilution for this sample. Therefore, the sample result is qualified as estimated (J). Affected data are summarized in Attachment 2. 5. PARCC Precision is defined as the agreement between duplicate results, and was estimated by comparing duplicate MS recoveries, and field duplicate sample results. The precision between the native and field duplicate sample results were within acceptable criteria indicating that the sample matrix did not interfere with the overall analytical process. Accuracy is a measure of the agreement between an experimental determination and the true value of the parameter. In the case of organic analysis, each of the samples were spiked with a surrogate compound with a known concentration before preparation. The surrogate and MS/MSD data provides a measure of the matrix effects as they may affect accuracy and precision of the analytical method. The LCS results demonstrate accuracy of the method. No spike recoveries exceeded the method acceptance limits indicating no matrix interference that affects the usability of the data. Representativeness criteria are a qualitative measure of the degree to which sample data accurately and precisely represent a characteristic environmental condition. Representativeness is a subjective parameter and is used to evaluate the efficacy of the sampling plan design. Representativeness was demonstrated by providing full descriptions in the project scoping documents of the sampling techniques and the rationale used for selecting sampling locations. Completeness is defined as the percentage of measurements that are judged to be valid compared to the total number of measurements made. There were no data rejected and or seen as not usable due to quality control or sampling issues. Comparability is another qualitative measure designed to express the confidence with which one data set may be compared to another. Factors that affect comparability are sample collection and handling techniques, sample matrix type, and analytical method. Comparability is limited by the other PARCC parameters because data sets can be compared with confidence only when precision and accuracy are known. Data from this investigation are comparable with other previous data collected at the site due to the laboratories use of EPA or appropriate methods to analyze the samples and supported by the results of the laboratory’s analytical reports. 6. Conclusion A review of the analytical data submitted regarding the investigation of PPL Greensboro Station sampling event in March 2024 by Jacobs has been completed. The validation demonstrated that the analytical systems were in control and all data results can be used in the decision-making process.
