(ATC) has completed an Active Remediation Monitoring Report for Former Star-Brite Laundry Facility. This report documents groundwater monitoring results and site activities for the period of June 2023 through December 2023. The former Star-Brite Laundry Facility is located at 5639 Statesville Road, Charlotte, North Carolina. The site consists of a single-story Ice-cream store with parking and landscaped areas. The site remediation system is located to the west of the existing single-story building. The property is currently owned by Mr. Johnny Keziah and Ms. Frances Keziah and occupied by Pelican’s Snoballs. ATC performed a semi-annual groundwater sampling event in October 2023 that consisted of the collection of groundwater samples from site monitoring and recovery wells, and from vicinity water supply wells. The collected data indicated that groundwater samples from monitoring wells MW-1A, MW-9A, and recovery wells RW-1 and RW-3 contained dissolved concentrations that exceeded the corresponding 2L Standards for at least one or more constituent(s). No constituents were detected above North Carolina GCLs during the October 2023 sampling event. Chloroform was detected in the samples from water supply wells WSW-1, WSW-2, and WSW-6 at levels consistent with prior detections. Methyl tertiary butyl ether (MTBE) was detected in WSW-1 and 1,2- dichloroethane was detected in WSW-1 and WSW-2, both at concentrations below their respective 2L Standards. Methylene chloride and methyl chloride were both detected for the first time in sampling history in all three- water supply well samples sampled in October 2023. Methylene chloride was also detected in the laboratory method blank. Both compounds are common laboratory contaminants, and detections are potentially the result of cross-contamination during laboratory analysis. Influent samples for RW-1/RW-3 and effluent samples were collected in July and October 2023. WSW-1 was also sampled during the July 2023 sampling. No constituents from either of the quarterly effluent samples collected during the reporting period exceeded their allowable limits by the NPDES permit. ATC is currently performing bi-weekly O&M visits at the site to ensure proper remedial system operation. The P&T system continues to be effective in the removal of petroleum-impacted groundwater. Based on the October 2023 groundwater monitoring event, ATC recommends continued operation of the P&T system combined with semiannual groundwater monitoring and quarterly system influent and effluent sampling. The next semi-annual groundwater monitoring event is scheduled for April 2024. 3.0 INTRODUCTION Phillips 66 Company (Phillips 66) retained ATC Associates of North Carolina, P.C. (ATC) to provide environmental consulting services for the former Star-Brite Laundry Facility. The site is located at 5639 Statesville Road, Charlotte, North Carolina. The property consists of a single-story Ice-cream store with parking and landscaped areas. Most of the eastern part of the site is covered by asphalt pavement, while most of the western part is covered with landscaped and grass-covered areas. The site remediation system is located to the west of the existing single-story building. Figure 1 shows the site location on a topographic map, and a site map showing the locations of the monitoring wells and remediation wells is included as Figure 2. The site is situated in a residential and commercial area within the city limits of Charlotte, North Carolina. The Oakdale Greenhouse facility is located on an adjacent property to the east across Statesville Road. The remaining vicinity land usage is primarily residential. Former Star-Brite Laundry Facility (RM No. 0528) February 20, 2024 Page 2 of 6 ATC Project No. P660528014 Phillips 66 Company 4.0 SITE BACKGROUND In November 1995, seven underground storage tanks (USTs) were removed from the site. The USTs consisted of three gasoline tanks, one diesel fuel tank, one kerosene tank, one heating oil tank, and one used oil tank. During the UST closure, approximately 600 tons of impacted soil was removed and disposed. The petroleum release was reported to the North Carolina Department of Environment and Natural Resources (NCDENR, currently the North Carolina Department of Environmental Quality [NCDEQ]) in November 1995. In August 1997, Rust Environment and Infrastructure (Rust) completed a Comprehensive Site Assessment (CSA). The CSA indicated that soil and groundwater contamination was confined to the site. In February 1998, the NCDEQ required a Corrective Action Plan (CAP), which was submitted by Rust in June 1998. The CAP identified air sparging (AS) and soil vapor extraction (SVE) as the most feasible technologies to remediate the petroleum-impacted soil and groundwater on-site. In February 2000, the AS/SVE system was started. Enhancements to the AS/SVE system and remediation wells were completed between 2000 and 2003, and a new AS compressor was installed in early 2006. The system provided treatment of on-site constituents from its activation in 2000 until November 2011, when failure of the SVE equipment occurred. Because remaining impact was limited to deep overburden and upper bedrock zones beyond the influence of the remedial system, the NCDEQ UST Section allowed development of a New Technology Cleanup Plan (NTCP) to address the remaining impact. Additionally, a road-widening project required abandonment of monitoring and remedial system wells, which would have also disrupted remedial operations. On November 6, 2012, the NTCP was submitted to the NCDEQ. The NTCP specified a Pump and Treat (P&T) system to extract and treat groundwater from the deep saprolite and upper bedrock zones with discharge into a storm drain via a National Pollutant Discharge Elimination System (NPDES) permit. The NPDES permit for the new P&T system was approved on February 21, 2014. Completion of a stormwater drop inlet that receives the treated water occurred in June 2014, and the building permit was approved by Mecklenburg County in July 2014. System start-up occurred on July 31, 2014, with continual operation thereafter. In April 2015, ATC supervised the abandonment of vapor extraction wells VE-6 through VE-10 that were associated with the former AS/SVE system, and monitoring well MW-1R, due to a blockage in the casing. Following the well abandonments, ATC supervised the installation of site monitoring wells MW-1A, MW-2A, MW-5A, MW-8A, MW-9A, and MW-11DA. Well MW-1A is a replacement well for well MW-1R, and wells MW-2A, MW-5A, MW-8A, MW-9A, and MW-11DA are replacement wells for wells that were previously abandoned for road widening construction along Statesville Road. The road-widening project was completed during the summer of 2015. On March 28, 2018, ATC supervised the installation of recovery well RW-3. The boring location was cleared to 5.5 feet below ground surface (bgs) using air-knife technology and drilled to 68 feet bgs using a hollow stem auger drill rig. Drilling was stopped at 68 feet bgs due to auger refusal. Recovery well RW-3 was installed to a total depth of 68 feet bgs, with a 35-foot length of 0.010-inch slotted, 4-inch diameter PVC well screen extending from 33 to 68 feet bgs, and solid PVC riser casing to the ground surface. The well was completed at ground surface using a flush-mount, traffic-rated 2-foot by 2-foot well vault secured in concrete to match existing grade. On April 25 and 26, 2018, ATC removed the pump from recovery well RW-2 and subsequently decontaminated the pump prior to installing it in newly installed well RW-3. Recovery well RW-2 was not abandoned and is used as a groundwater monitoring point during groundwater monitoring events. The treatment system continues to recover impacted groundwater. Groundwater is recovered from two recovery wells equipped with electric submersible pumps and is then treated using an air stripper and bag filters, prior to discharge. The groundwater is discharged in accordance with NPDES General Permit No. NCG510000. Former Star-Brite Laundry Facility (RM No. 0528) February 20, 2024 Page 3 of 6 ATC Project No. P660528014 Phillips 66 Company 5.0 GROUNDWATER CHARACTERIZATION 5.1 GROUNDWATER LEVELS On October 23, 2023, groundwater levels were measured in the site monitoring well network. LNAPL was not detected in any site wells. Depths were measured from the top of the well casings, which are referenced to an arbitrary benchmark of 100.00 feet. The October 23, 2023, groundwater contour map for the shallow saprolite aquifer shows that shallow groundwater flow delineated by wells MW-1A, MW-2A, MW-3R, MW- 5A, MW-6R, MW-7, MW-8A and MW-9A has an overall groundwater flow direction to the east-southeast. The groundwater contour map for the deep fractured rock aquifer shows that deep groundwater flow delineated by wells MW-4D, MW-10D, MW-11DA, and MW-12D has an overall groundwater flow direction to the west-northwest. Well construction details for the monitoring wells are summarized in Table 1. The locations of the monitoring wells are shown in Figure 2, and the groundwater elevation data is summarized in Table 2. A groundwater elevation contour map for the shallow saprolite and deep fractured rock aquifers based on the October 2023 gauging data are included as Figures 3a and 3b. 5.2 GROUNDWATER QUALITY On October 23 and 24, 2023, ATC personnel conducted a groundwater monitoring event of the site well network, including recovery wells, RW-1, RW-2, and RW-3. The groundwater samples were transported on ice and under chain-of-custody documentation to North Carolina-accredited SGS-Accutest laboratory located in Orlando, Florida (North Carolina Lab Certification No. 573). The samples were analyzed for volatile organic compounds (VOCs), including benzene, toluene, ethylbenzene, total xylenes (BTEX), MTBE, isopropyl ether (IPE), and naphthalene by EPA Method 6200B and low-level ethylene dibromide (EDB) by EPA Method 504.1. The laboratory report for the October 2023 sampling event is included in Appendix A. Groundwater quality results exceeded the NCDEQ Groundwater Quality 2L Standards for the following constituents and monitoring well locations:  MTBE (2L Standard of 20 µg/L) in wells MW-9A (58.7 µg/L), RW-1 (27.0 µg/L), and RW-3 (65.6 µg/L);  Naphthalene (2L Standard of 6 µg/L) in well MW-1A (22.5 µg/L); and  1,2-Dichloroethane (1,2-DCA; 2L Standard of 0.4 µg/L) in wells MW-9A (1.2 µg/L), RW-1 (1.1 µg/L), and RW-3 (3.3 µg/L). None of the detected constituents exceeded their respective GCLs in the site monitoring or recovery wells. Groundwater analytical results for the October 2023 sampling event are summarized in Table 3, and historical groundwater analytical results are summarized in Table 4. Isoconcentration maps are provided for the following constituents: MTBE (Figure 4); and 1,2-DCA (Figure 5). 5.3 WATER SUPPLY WELLS Correspondence from the NCDEQ, dated April 23, 2003, stated that water supply wells within 500 feet of the site should be sampled. Information for each property is summarized in Table 5, and the locations of the properties with water supply wells are shown on Figure 6. On July 18, 2023, a sample was collected from water supply well WSW-1 located at the Oakdale Nursery property (5626 Statesville Road). On October 24, 2023, samples were collected from water supply wells, WSW-1 and WSW-2, located at the Oakdale Nursery property (5626 Statesville Road), and WSW-6 at the Wallace property (6325 Burmith Former Star-Brite Laundry Facility (RM No. 0528) February 20, 2024 Page 4 of 6 ATC Project No. P660528014 Phillips 66 Company Avenue). Samples could not be collected at WSW-3, WSW-4, WSW-5, and WSW-7 due to lack of power at each respective well pump. Each of the properties that contain WSW-3, WSW-4, WSW-5, and WSW-7 are connected to municipal water provided by the City of Charlotte. The water supply well samples were transported on ice and under chain-of-custody to SGS-Accutest laboratory located in Orlando, Florida. The water supply well samples were analyzed for VOCs including BTEX, MTBE, IPE and naphthalene by EPA Method 6200B. Each sample was additionally analyzed for low level EDB by EPA Method 504.1. The laboratory reports are included in Appendix A, and laboratory results are summarized in Table 6. Chloroform was detected in water supply wells WSW-1, WSW-2, and WSW-6 at concentrations that did not exceed the 2L Standard and at levels consistent with prior detections. MTBE was detected in WSW-1 and 1,2-dichloroethane was detected in WSW-1 and WSW-2, both at concentrations below their respective 2L Standards. Methylene chloride and methyl chloride were both detected for the first time in sampling history in all three- water supply well samples collected in October 2023. Methylene chloride was also detected in the laboratory method blank. Both compounds are common laboratory contaminants, and detections are potentially the result of cross-contamination during laboratory analysis. Overall, ATC concludes that the laboratory results are usable and any exceptions do not significantly impact the conclusions presented in this report. 6.0 REMEDIATION SYSTEM OPERATIONS AND MAINTENANCE 6.1 REMEDIAL SYSTEM Historically, an air sparge and soil vapor extraction (AS/SVE) system operated on site from February 2000 until 2012. In November 2012, a New Technology Cleanup Plan (NTCP) specifying pump and treat (P&T) technology was completed and approved by NCDEQ. The remediation wells associated with the AS/SVE system were abandoned in August 2013, and April 2015. The AS/SVE system was decommissioned and removed from the site in August 2013. The new P&T system was delivered to the site in February 2014, following approval of the NPDES permit on February 21, 2014. Trenching of the discharge line to the drop inlet that now serves as the point of discharge took place in April 2014. The drop inlet was completed in June 2014 by a third-party road construction contractor. Following permit approval by Mecklenburg County, the P&T system was started on July 31, 2014. Bi-weekly O&Ms have been conducted since remedial system startup to ensure proper system operation. Recovery well RW-3 was installed at the site to remove petroleum-impacted groundwater and has replaced recovery well RW-2 as an active recovery well. Recovery well RW-2 will continue to be used as a groundwater monitoring point. A new submersible pump was installed at RW-3 during the 2019 reporting period due to pump failure. From June 1, 2023, through December 31, 2023, the remedial system operated for approximately 212 days out of a possible 214 days. Minimal system shutdown resulted from routine scheduled maintenance throughout the reporting period and a groundwater sampling event in October 2023. The average dissolved VOC mass removal during the reporting period was estimated as 0.37 grams/day. 6.2 SYSTEM SAMPLING Influent samples for RW-1/RW-3 and effluent samples were collected in July and October 2023. The samples were sent to SGS Acutest in Orlando, Florida for analysis. Each sample was analyzed by EPA Method 6200B for VOCs, EPA Method 6010C for lead, and EPA Method SM-20, 2540D for TSS, and tested for pH as required by the NPDES permit. Former Star-Brite Laundry Facility (RM No. 0528) February 20, 2024 Page 5 of 6 ATC Project No. P660528014 Phillips 66 Company No constituents from either of the quarterly effluent samples collected during the reporting period exceeded their allowable limits by the NPDES permit. The laboratory results for remedial system sampling are summarized in Table 7 and included in Appendix B, with a Graph (following Figure 6) showing the trend of MTBE concentrations vs Time in active recovery well RW-3. 7.0 PLAN AND SCHEDULE 7.1 SITE ACTIVITIES The next semi-annual sampling event is proposed for April 2024. Monitoring well and water supply well samples will be analyzed for VOCs (including BTEX, MTBE, IPE, and naphthalene) by EPA Method 6200B and low level EDB by EPA Method 504.1. Quarterly treatment system effluent sampling will be conducted in January and April 2024. Each effluent sample will be analyzed for benzene, ethylbenzene, toluene, total xylenes, 1,2-dichloroethane, MTBE, and naphthalene by EPA Method 6200B, lead by EPA Method 6010C, and TSS by EPA Method SM-20, 2540D in accordance with the NPDES permit. Active Remediation Monitoring Reports will be submitted semi- annually. Operation and maintenance for the P&T system will continue to occur on a bi-weekly basis. 8.0 SUMMARY, CONCLUSIONS, AND RECOMMENDATIONS During this reporting period, bi-weekly maintenance of the P&T remedial system was conducted. ATC performed a semi-annual groundwater-sampling event in October 2023 that consisted of the collection of groundwater samples from site monitoring and recovery wells, and from vicinity water supply wells. The collected data indicated that groundwater samples from monitoring wells MW-1A, MW-9A, and recovery wells RW-1 and RW-3 contained dissolved concentrations that exceeded the corresponding 2L Standards for at least one or more constituent(s). No constituents were detected above North Carolina GCLs during the October 2023 sampling event. Chloroform was detected in water supply wells WSW-1, WSW-2, and WSW-3 at concentrations that did not exceed the 2L Standard and at levels consistent with prior detections. MTBE was detected in WSW-1 and 1,2-dichloroethane was detected in WSW-1 and WSW-2, both at concentrations below their respective 2L Standards. Methylene chloride and methyl chloride were both detected for the first time in sampling history in all three- water supply well samples sampled in October 2023. Methylene chloride was also detected in the laboratory method blank. Both compounds are common laboratory contaminants, and detections are potentially the result of cross-contamination during laboratory analysis. MTBE is the primary contaminant of concern. The highest MTBE concentrations are typically present in the eastern portion of the site in an area defined by wells RW-1, RW-3, and MW-9A. MTBE concentrations in well RW-2 have been below the 2L Standard since the April 2016 groundwater monitoring event. The highest MTBE concentrations have been detected in the groundwater samples collected from recovery well RW-3, which is an active recovery well with the current remedial system. The P&T system continues to be effective in the removal of petroleum-impacted groundwater. Based on the October 2023 groundwater monitoring event, ATC recommends continued operation of the P&T system combined with semiannual groundwater monitoring and quarterly system influent and effluent sampling. The next semi-annual groundwater monitoring event is scheduled for April 2024. 9.0 REPORT LIMITATIONS This investigation is intended to be a non-biased assessment of on-site environmental conditions proximate to the location of the former and/or current UST system.
