Apex Companies, LLC (Apex; dba Maryland Apex Engineering, PC) prepared this report on behalf of CPC for submittal to the North Carolina Department of Environmental Quality (NCDEQ) and the Guilford County Department of Health and Human Services. In a letter dated March 19, 2019, Apex submitted a revised semiannual groundwater monitoring program for the site which proposed a limited downgradient/compliance boundary monitoring event of the greater property outside of the Tank 845 Area each April and a full monitoring event in the Tank 845 Area each October. All seven monitoring wells included in the Tank 845 Area are gauged annually and are sampled only during the October monitoring event. Table 1 presents a summary of the semiannual groundwater monitoring program for the site approved by the NCDEQ in a letter dated April 8, 2019. A site plan showing the facility layout and property boundaries on an aerial photograph is provided as Figure 1. Three separate groundwater monitoring and remediation programs are administered at the facility. These programs include: A Gasoline Side Program which covers all investigation/remediation areas located on the western side of the Upper and Lower Ponds (Incident Number 5153); A Tank 845 Program which covers the investigation/remediation area around Tank 845 (Incident Number 95301); and, A Distillate Side Program which covers all investigation/remediation areas located on the eastern side of the Upper and Lower Ponds (Incident Numbers 18126 & 95300). Multiple hydrocarbon plumes are located on the Gasoline Side of the facility. The Tank 845 Area is a sub- area within the Gasoline Side of the facility. The historic release areas are shown on Figure 2. On July 16, 2013, a petroleum release was discovered at the Tank 845 Area on the Gasoline Side of the facility. Approximately 250 gallons of diesel fuel were released to the soil beneath and in the immediate vicinity of Tank 845. The release is believed to have been caused by a crack in the weld of the tank floor near the sump. Initial abatement activities consisted of the recovery of approximately 150 gallons of light non-aqueous phase liquid (LNAPL) fuel and the excavation of impacted soil along the southeast and east sides of Tank 845. The aboveground storage tank was subsequently raised and the impacted soil beneath the tank floor was removed. A Corrective Action Plan (CAP) was prepared to address the July 16, 2013 Tank 845 release and submitted to NCDEQ, Underground Storage Tank (UST) Section on February 27, 2015. The CAP was approved by the NCDEQ, UST Section in a letter dated March 16, 2015, which included soil vapor extraction (SVE) to Colonial Pipeline Company – Greensboro Junction June 29, 2023 Annual Monitoring Report – Tank 845 Page 2 address impacted soils and monitored natural attenuation (MNA) to address impacted groundwater. However, since the submittal and approval of the CAP, North Carolina House Bill 765 (HB 765) was passed on October 22, 2015 allowing for the risk-based closure of petroleum releases from sources other than USTs. Following the passage of HB 765 and promulgation of 15A NCAC 2L .0500, CPC received approval from NCDEQ to omit installation and operation of the SVE system in the Tank 845 Area as industrial/commercial Maximum Soil Contaminant Concentrations (MSCCs) were not exceeded. The risk classification criteria for a site established under 15A NCAC 2L .0506 is based on several factors, including the presence of LNAPL and the distance from the source area of a release to receptors such as surface water bodies, water supply wells and wellhead protection areas. Based on the risk-based rules established by 15A NCAC 2L .0500, the Tank 845 Incident Number 95301 is classified as low risk because LNAPL has not been detected in the Tank 845 Area monitoring well network since June 2013, and the nearest surface water body is located greater than 500 feet from the impacted area. Groundwater cleanup goals for the Tank 845 Area are the Gross Contaminant Levels (GCLs) established for low risk sites. The site plan in Figure 1 shows the approximate 500-foot buffer around surface water bodies. 2.0 GROUNDWATER MONITORING 2.1 Groundwater Gauging and LNAPL Thickness Measurements On October 3, 2022, water level and LNAPL thickness measurements, if present, were collected from monitoring wells included in the Tank 845 Area monitoring program. A decontaminated electronic oil/water interface probe was used to collect the liquid level measurements from each well. A total of seven wells were gauged during the October 2022 sampling event. 2.2 Groundwater Sampling and Analysis Groundwater samples were collected for laboratory analysis from seven monitoring wells during the October 2022 sampling event. Groundwater sampling field logs are presented in Appendix A. HydraSleeve™, a no-purge sampling system, was used to sample each well during the October 2022 sampling event. NCDEQ approved the use of no-purge groundwater sampling techniques in a letter dated March 28, 2016. Groundwater samples were collected in appropriate containers (preserved as required) pending shipment for laboratory analyses at Pace Analytical Services, LLC of Huntersville, North Carolina. Groundwater samples were analyzed for benzene, toluene, ethylbenzene, and total xylenes (BTEX), methyl tert-butyl ether (MTBE), and naphthalene in accordance with Environmental Protection Agency SW-846 Method 8260D. Colonial Pipeline Company – Greensboro Junction June 29, 2023 Annual Monitoring Report – Tank 845 Page 3 3.0 FINDINGS 3.1 Groundwater Gauging and LNAPL Thickness Measurements Groundwater gauging results from the October 2022 event are summarized in Table 2. Depth to water and top of well casing elevations were used to determine groundwater elevations relative to an on-site benchmark using mean sea level (MSL) datum. For shallow wells that are screened across the water table, the groundwater potentiometric surface is approximately equal to the water table elevation. A groundwater potentiometric surface map was developed for the entire CPC facility based on the October 2022 data and is shown as Figure 3. Gauging data indicates the direction of groundwater flow in the overburden aquifer beneath the Gasoline Side of the facility is east-southeast and the flow direction is consistent with historical results. Site-wide groundwater flow converges toward discharge zones located at the upper and lower ponds and the Southern Area drainage feature. Shallow groundwater flow north of Tank 826 is influenced by local topography and a northwest-southeast trending drainage feature. In the Tank 845 Area, the hydraulic gradient was calculated as 0.022 feet per foot by dividing the vertical difference between the 875 MSL equipotential contour line near the east side of Tank 845 and the 855 MSL equipotential contour line near the west side of Tank 826. LNAPL was not detected in any monitoring wells that were gauged in the Tank 845 Area during the October 2022 monitoring event. 3.2 Groundwater Analytical Results The groundwater analytical results from the October 2022 sampling event are summarized with the historical analytical results in Table 3. Laboratory analytical data reports and chain-of-custody records for the October 2022 event are provided in Appendix B. The laboratory report narrative for October 2022 samples, lot number: XJ07026, indicates that initial analyses conducted within hold time, some samples were reanalyzed out of hold time to address various quality control issues. Where possible, the laboratory reanalyzed individual analytes to minimize out of hold time analyses. Benzene was detected in three of the seven monitoring wells (MW-124, MW-140, and MW-223) during the October 2022 sampling event. Benzene detections were above the 2L Standard of 1 g/L but below the applicable GCL of 5,000 g/L for low risk sites. Figure 4A presents the distribution of benzene in groundwater for the Gasoline Side of the facility, and Figure 4B presents the distribution of benzene in groundwater at the Tank 845 Area during the October 2022 sampling event. Toluene was detected in two of the seven monitoring wells (MW-124 and MW-140) during the October 2022 sampling event. The toluene detection in MW-140 was above the 2L Standard of 600 g/L but below the Colonial Pipeline Company – Greensboro Junction June 29, 2023 Annual Monitoring Report – Tank 845 Page 4 applicable GCL of 260,000 g/L. Figure 5A presents the distribution of toluene in groundwater for the Gasoline Side of the facility, and Figure 5B presents the distribution of toluene in groundwater at the Tank 845 Area during the October 2022 sampling event. Ethylbenzene was detected in three of the seven monitoring wells (MW-124, MW-140, and MW-223) during the October 2022 sampling event. Ethylbenzene detection in MW-140 was above the 2L Standard of 600 g/L but below the applicable GCL of 80,000 g/L. Figure 6A presents the distribution of ethylbenzene in groundwater for the Gasoline Side of the facility, and Figure 6B presents the distribution of ethylbenzene in groundwater at the Tank 845 Area during the October 2022 sampling event. Total xylenes were detected in four of the seven monitoring wells (MW-124, MW-139, MW-140, and MW-223) during the October 2022 sampling event. Total xylenes detections were above the 2L Standard of 500 g/L but below the applicable GCL of 50,000 g/L for low risk sites at MW-124 and MW-140. Figure 7A presents the distribution of total xylenes in groundwater for the Gasoline Side of the facility, and Figure 7B presents the distribution of total xylenes in groundwater at the Tank 845 Area during the October 2022 sampling event. MTBE was detected in four of the seven monitoring wells (MW-30, MW-124, MW-223, and MW-224) during the October 2022 sampling event. The MTBE detection in MW-30 was above the 2L Standard of 20 g/L but below the applicable GCL of 20,000 g/L. MTBE detections were below the 2L Standard of 20 g/L in all other monitoring wells. Figure 8A presents the distribution of MTBE in groundwater for the Gasoline Side of the facility, and Figure 8B presents the distribution of MTBE in groundwater at the Tank 845 Area during the October 2022 sampling event. Naphthalene was detected in three of the seven monitoring wells (MW-124, MW-140, and MW-223) during the October 2022 sampling event. Naphthalene detections exceeded the 2L Standard of 6 g/L in wells MW-124, MW-140, and MW-223, but were below the applicable GCL of 6,000 g/L for low risk sites. Figure 9A presents the distribution of naphthalene in groundwater for the Gasoline Side of the facility, and Figure 9B presents the distribution of naphthalene in groundwater at the Tank 845 Area during the October 2022 sampling event. As shown on the figures, the Tank 845 dissolved phase plume is comingled with a historic pre-1990s release in the Tank 844-845 Area. The highest BTEX and naphthalene concentrations were observed in well MW-140 located upgradient of the 2013 Tank 845 release area. BTEX and naphthalene detections in MW-140 are a result of historic releases in the Tank 844-845 Area that predate the 1990s. MTBE detections in the Tank 845 Area are also attributed to the historic releases in the Tank 844-845 area as the 2013 Tank 845 Release involved fuel distillate. Colonial Pipeline Company – Greensboro Junction June 29, 2023 Annual Monitoring Report – Tank 845 Page 5 LNAPL has not been detected in the Tank 845 Area in over eight years and the groundwater data indicate that dissolved hydrocarbons are below their respective GCLs and continue to naturally attenuate. 4.0 CONCLUSIONS AND RECOMMENDATIONS Dissolved-phase hydrocarbon concentrations in groundwater beneath the Tank 845 Area are below applicable GCLs and LNAPL has not been detected in the Tank 845 Area monitoring wells after initial LNAPL recovery efforts were performed following discovery of the distillate release in July 2013. As previously stated, there are three separate groundwater monitoring and remediation programs administered at the facility: (i) The Gasoline Side Program, (ii) the Tank 845 Area Program, and (iii) the Distillate Side Program. A separate annual monitoring report is submitted to NCDEQ for each area. The groundwater monitoring programs and annual monitoring reports for the Gasoline Side and Distillate Side of the facility cover multiple historic release incidents. The Tank 845 Area is located on the Gasoline Side of the facility, and accordingly the results of the Tank 845 Area groundwater sampling program are presented in the Annual Report for the Gasoline Side of the facility. The groundwater plume in the Tank 845 area is stable and dissolved phase petroleum constituent concentrations are below applicable GCLs with decreasing trends for BTEX, naphthalene and MTBE. Since the information presented in the annual report for the Tank 845 Area is redundant with the information presented in the Annual Report for the Gasoline Side of the facility, it is recommended that submittal of an Annual Monitoring Report specifically for the Tank 845 Area be discontinued.
