(ATC), on behalf of Cary Oil Company (Cary Oil), is submitting a Corrective Action Performance Report which summarizes historical remedial efforts and Air Sparge/Soil Vapor Extraction (AS/SVE) system operation and maintenance (O&M) activities conducted in January 2017. As outlined in the October 31, 2012, Corrective Action Plan (CAP), high vacuum extraction through the implementation of Aggressive Fluid/Vapor Recovery (AFVR) technology appeared to be the most feasible and cost effective option for recovering remaining free product from on-site well MW-8. AFVR events were conducted between March 2012 and December 2013 and recovered approximate totals of 44 gallons of liquid phase product, 54.17 gallons of vaporized product, and 1,870 gallons of petroleum contact water from well MW-8. Historical free product recovery information is summarized in Table 1. Adsorbent socks were installed and changed as necessary in well MW-8 beginning in February 2015 to recover remaining free product. The sock was removed in early July 2015, and the well has not indicated free product during subsequent groundwater monitoring events. Natural attenuation was determined in the CAP to be the most feasible and cost effective remedial option for reducing groundwater contaminant concentrations in portions of the intermediate and deep zones of the unconfined aquifer. Historical natural attenuation sampling indicates an environment conducive to potential bioremediation in the intermediate and deep aquifer zones. Generally, measured dissolved oxygen concentrations are consistently above anoxic and hypoxic conditions, indicating a potential for aerobic activity. Dissolved oxygen concentrations in wells IMW-1 and DMW-1 remain particularly high. Petroleum compound concentrations had generally shown an increasing trend in downgradient, intermediate well IMW- 1, until January 2016 when concentrations began decreasing. Some contaminant concentration rebounding was observed in well IMW-1 during a recent monitoring event in December 2016, but the increases may be Cajah’s Mountain Superette – Corrective Action Performance Report March 9, 2017 NCDEQ Incident No. 28649 ATC Project No. CARCAJA 2 due to off-site system downtime. Impact in this well will continue to be monitored and remedial system adjustments should be made as deemed necessary. Impact in on-site, deep well DMW-1 is generally decreasing with time. Contaminants of concern in other intermediate and deep wells remain minimal. The CAP identified AS/SVE as the chosen corrective action technologies for shallow petroleum-impacted groundwater at this site. Air sparge and soil vapor extraction wells were installed at the site on December 30, 2013, through January 15, 2014. The on-site and off-site system installations were completed on January 13, 2014, through January 24, 2014. System startup activities were conducted on March 26, 2014. However, due to noise concerns, the off-site system was turned off until April 9, 2014, when the telemetry was programmed to operate the system from 8:00 am to 8:00 pm. Scheduled O&M site visits were conducted by ATC personnel on January 18 and January 31, 2017. On-site system run-time was 99% from January 18 to January 31, 2017. Vacuum readings for each well point at the on-site SVE manifold were set at approximately 40 inches of water. Following a reduction in measurable product at the site, sparge wells AS-1 through AS-3 were started in October 2015. Pressure readings for each well point at the on-site AS manifold were set at approximately eight psi. The off-site system was not operational from January 18 to January 31, 2017. Downtime was generally attributable to a power fault which resulted in burned SVE motor wires. A local motor repair shop assessed the blower motor and identified the following: one endbell needs to be bushed and the motor needs new bearings, lip seal, and filter media. ATC submitted a request for pre-approval of costs for these repairs to the NCDEQ on March 7, 2017. Additional off-site system assessment may be required following completion of repairs by the motor repair shop. As discussed in an Active Remediation Monitoring Report, dated February 13, 2017, effluent air samples were collected from the on-site and off-site SVE systems on December 14, 2016, to evaluate petroleum vapor removal and to assist with system optimization efforts. The air samples were submitted to Prism Laboratories, Inc. for analysis by EPA Method TO-18. Table 2 shows SVE cumulative recovery calculations based on system effluent sampling data. Assuming consistent recovery during each day of operation between sampling dates, approximately 899.1 and 41.5268 pounds of total BTEX have been recovered by the on-site and off- site SVE systems, respectively, from startup through December 14, 2016. A groundwater monitoring event was conducted at the site on December 28 and 29, 2016. Groundwater contamination above NCDEQ 2L standards is generally located in front of the on-site building in the vicinity of the former UST system and migrates downgradient to the east-southeast across Connelly Springs Road towards well IMW-1 and slightly to the southwest towards wells MW-9 and DMW-2. Contaminant concentrations in the source area generally indicate a decreasing trend with time, though some rebounding was observed in December 2016. Adjustments to the off-site SVE system were made in April 2016 to focus efforts on the western portion of the off-site property. In July 2016, significantly lower contaminant concentrations were observed in off-site well MW-11 which has historically contained the highest off-site shallow aquifer impact concentrations. Off-site contaminant concentrations generally increased in December 2016 during system downtime. ATC recommends continued AS/SVE system O&M visits and site groundwater monitoring at the Cajah’s Mountain Superette site. System O&M visits should continue to be conducted twice per month and continued efforts to troubleshoot the off-site system issues should be implemented. Quarterly SVE effluent air sampling is recommended during scheduled O&M visits. ATC recommends groundwater monitoring events be conducted on a semi-annual basis during winter and summer months.

(ATC) to prepare a Corrective Action Performance Report for the project site located at 1990 Connelly Springs Road in Lenoir, Caldwell County, North Carolina. Figure 1 shows the site and vicinity on part of a United States Geological Survey (USGS) site topographic map. A map showing site details is provided as Figure 2. This report documents three months of remedial system operation and maintenance. Groundwater impact at the site has historically been identified at concentrations exceeding Gross Contamination Levels (GCLs). Generally decreasing trends have been observed over time. However, according to groundwater analytical results obtained from a monitoring event performed on December 28 and 29, 2016, contaminant concentrations increased, and benzene was reported in well MW-8 at a concentration above the GCL. The remedial systems were not operational during the December 2016 groundwater monitoring event and that may be the reason for observed increased dissolved impact. Petroleum hydrocarbons were detected above the associated 15A NCAC 2L .0202 Standards (2L Standards) in eight of the 14 sampled site monitoring wells in December 2016. Historical groundwater sampling results are provided in Table 3. Free product has historically been identified in site well MW-8 at a maximum thickness of 2.97 feet. Free product was not identified in site monitoring wells in December 2016. As outlined in the October 31, 2012, Corrective Action Plan (CAP), high vacuum extraction through the implementation of Aggressive Fluid/Vapor Recovery (AFVR) technology appeared to be the most feasible and cost effective option for recovering remaining free product from on-site well MW-8. AFVR events were conducted between March 2012 and December 2013 and recovered approximately 44 gallons of liquid phase product, 54.17 gallons of vaporized product, and 1,870 gallons of petroleum-contact water from well MW-8. Historical free product recovery information is summarized in Table 4. Adsorbent socks were installed and changed as necessary in well MW-8 beginning in February 2015 to recover remaining free product. The sock was removed in early July 2015, and the well has not indicated free product during subsequent groundwater monitoring events. Natural attenuation was determined in the CAP to be the most feasible and cost effective remedial option for reducing groundwater contaminant concentrations in the intermediate and deep aquifer zones. Historical natural attenuation sampling indicates an environment conducive to potential bioremediation in the intermediate and deep aquifer zones. Generally, measured dissolved oxygen concentrations are consistently Cajah’s Mountain Superette November 1, 2017 Corrective Action Performance Report Page 2 above anoxic and hypoxic conditions, indicating a potential for aerobic activity. Dissolved oxygen concentrations in wells IMW-1 and DMW-1 tend to be particularly high. Natural attenuation parameters are presented in Table 5. Petroleum compound concentrations had generally shown an increasing trend in downgradient, intermediate well IMW-1, until January 2016 when concentrations began decreasing. Some contaminant concentration rebounding was observed in well IMW-1 during a recent monitoring event in December 2016, but the increases may be due to off-site system downtime. Impact in this well will continue to be monitored and remedial system adjustments should be made as deemed necessary. Impact in on-site, deep well DMW-1 is generally decreasing with time. Contaminants of concern in other intermediate and deep wells remain minimal. The CAP identified air sparge/soil vapor extraction (AS/SVE) as the chosen corrective action technologies for shallow petroleum-impacted groundwater at the site. Air sparge and soil vapor extraction wells were installed at the site on December 30, 2013, through January 15, 2014. The on-site and off-site system installations were completed on January 13, 2014, through January 24, 2014. System startup activities were conducted on March 26, 2014. However, due to noise concerns, the off-site system was turned off until April 9, 2014, when the telemetry was programmed to operate the system from 8:00 am to 8:00 pm. Based on impact to vicinity water supply wells and historical free product and groundwater impact in site monitoring wells, the risk classification for the site has been designated as “High” and ranked H190D by the North Carolina Department of Environmental Quality (NCDEQ). Therefore, groundwater contamination must be remediated to concentrations which are equal to or less than the associated 2L Standards. 2.0 SUPPORTING INFORMATION AND CAP IMPLEMENTATION An underground storage tank (UST) system consisting of three tanks was formerly located on-site and was operated by Cary Oil from April 2005 until August 2008 when the UST system was removed. During UST removals, soil impact was identified and led to assessment requests from the North Carolina Department of Environment and Natural Resources (NCDENR; currently the NCDEQ). The subject property is owned by Mary Lindsay and has one building that currently operates as a catering business known as Mooresridge Catering. The site formerly operated as a convenience store which included a UST system consisting of two 8,000-gallon gasoline USTs and one 4,000-gallon gasoline Cajah’s Mountain Superette November 1, 2017 Corrective Action Performance Report Page 3 UST. Site history including on-site UST system information is summarized in Table 1. A site plan that indicates monitoring well locations and other site features is provided as Figure 2. The perennial surface water body identified in the closest proximity to the site is Stafford Creek located approximately 2,000 feet to the southwest of the site. A branch of Little Gunpowder Creek lies approximately 2,500 feet to the east of the site. The Caldwell County Geographic Information System database identified surface water bodies towards the east and west at distances of 700 and 500 feet from the site, respectively; however, these surface water bodies were not identified during field activities. Surface cover at the site consists mostly of asphalt on the east side of the property and grass and gravel on the west side of the property. The site lies in the Inner Piedmont in an area characterized by inter-fingered biotite gneiss, biotite schist, and mica schist with some other minor rock types that are heavily metamorphosed and structurally complex. The shallow subsurface contains overburden of soil, saprolite, and partially weathered rock (PWR) that derive from in-place weathering. Findings from the Comprehensive Site Assessment (CSA) suggest that most of the unconsolidated subsurface materials exhibit high permeability for the Piedmont and probably can best be described as saprolite or PWR. During assessment activities, rock was encountered at decreasing depths with distance from the site towards the east, with depths ranging from 85 feet below ground surface (bgs) at on-site well DMW-3 to 20 feet bgs at downgradient well MW-21. Depth to groundwater in the site monitoring wells ranged from approximately 25 to 35 feet below top of casing (TOC) during the December 2016 groundwater sampling event. Based on the recent groundwater level measurements and calculation of groundwater elevations, groundwater flows towards the east-southeast across the site. Baton Water Corporation and the Town of Lenoir supply public water in the site vicinity. Twenty-one (21) private water supply wells have been identified within approximately 1,500 feet of the site. Water supply well information for the area is summarized in Table 2, and supply well locations relative to the source area are depicted on Figure 3. Between 2008 and 2012, site assessment, AFVR events for free product recovery, and a CAP with pilot testing were conducted related to the Cajah’s Mountain Superette release. Free product recovery efforts in the form of AFVR events, conducted between 2012 and 2013 recovered approximately 44 gallons of liquid phase product, 54.17 gallons of vaporized product, and 1,870 gallons of petroleum-contact water from well MW-8. Cajah’s Mountain Superette November 1, 2017 Corrective Action Performance Report Page 4 Historical free product recovery information is summarized in Table 4. Adsorbent socks were installed and changed as necessary in well MW-8 between February 2015 and July 2015, and the well has not indicated free product during subsequent groundwater monitoring events. Based on results of the CAP and pilot testing, ATC found that AS and SVE technologies appeared to be the most feasible and cost effective remedial options for reducing groundwater contaminant concentrations in the shallow aquifer, and monitored natural attenuation was chosen for groundwater in the intermediate and deep zones. The AS/SVE wells were installed from December 30, 2013, to January 15, 2014. Depths of the air sparge wells ranged from 50 feet to 95 feet bgs, depending on zones of groundwater impact and depth of bedrock. Wells SVE-2 through SVE-7 and SVE-10 through SVE-14 were installed to depths of 34 feet or 35 feet bgs, depending on vicinity groundwater levels. Wells SVE-8 and SVE-9 were installed to depths of 26 feet bgs due to the elevated water table encountered behind the on-site building. Vapor extraction well SVE-1 was installed to a depth of 35 feet bgs on August 22, 2012, for the pilot study. The systems were installed during the period of December 2013 through January 2014. The on-site and off- site air sparge systems consist of six and eight air sparge wells, respectively, rotary claw air compressors, and schedule 80 PVC piping for transferring compressed air from the remediation systems to the air sparge wells. The on-site and off-site vapor extraction systems consist of nine and five vapor extraction wells, respectively, regenerative vacuum blowers, condensate collection vessels, and schedule 40 PVC piping for transferring extracted vapors from the vapor extraction wells to the remediation systems. A system design drawing is included as Figure 4. 3.0 GROUNDWATER REMEDIATION System startup activities were conducted on March 26, 2014. However, due to noise concerns, the off-site system was turned off until April 9, 2014, when the telemetry could be programmed to operate the system from 8:00 am to 8:00 pm. Efforts have been made to reduce excessive noise that originates from the building but minimal reductions have been observed. Air sparge wells AS-1 through AS-3 were left off, by means of closed system manifold valves, until free product was sufficiently recovered from the area. Following a reduction in measurable product at the site, sparge wells AS-1 through AS-3 were started in October 2015. Off-site wells AS-10 and AS-11 were shut down on April 13, 2016, and wells AS-9 and AS-12 were shut down on April 28, 2016, to provide more Cajah’s Mountain Superette November 1, 2017 Corrective Action Performance Report Page 5 sparge pressure to the west side of the off-site property where higher dissolved contaminant concentrations exist. On-site system downtime has historically often been attributable to high temperature alarms which shut the system down during summer months, and power losses following storms. Off-site system downtime in 2014 occurred due to bad motor windings on the SVE blower which shut the system down. The off-site SVE blower was replaced under warranty by the system fabricator on October 15, 2014. Electrical issues (power outages, phase losses, and an indicated electrical fault) occurred at both the on-site and off-site systems in 2015. The systems were ultimately shut down manually by ATC as a safety precaution. The issue was identified to be melted high voltage fuses in each system which led the systems to run on one phase and then shut down. A small fire at the on-site catering business building occurred in August 2015, which Duke Energy attributed to insufficiently sized wires for the load. The wires were subsequently changed by Duke Energy. The combined issues are potentially related to a general electrical issue in the area, possibly caused by recent electrical storms. High voltage fuses on the on-site and off-site SVE blowers were replaced in October 2015 and the systems were re-started. Due to frequent shutdowns, the off-site SVE blower vacuum was reduced in 2016 as it was determined the operating capacity of the unit could not be fully achieved in the actual operating conditions. That is to say, the potential capacity of the blower is assumed under ideal conditions which are rarely achieved in an environmental, non-climate controlled setting. System operation and maintenance was conducted twice per month from February to April 2017 to check system components and perform routine maintenance. Efforts are made to combine site visits with visits conducted at another Cary Oil site in the vicinity, Tilley’s Superette. On-site system run-time was approximately 93% from February to April 2017. System downtime was due to a phase fault from storms in the area during the reporting period. Vacuum readings for each well point at the on-site SVE manifold were set at approximately 40 inches of water. Pressure readings for each well point at the on-site AS manifold were set at approximately nine pounds per square inch (psi). The off-site system was not operational from February to April 2017. The system downtime began in December 2016 and was generally attributable to a power fault which resulted in burned SVE motor wires. A local motor repair shop assessed the blower motor and identified the following: one endbell needs to be bushed and the motor needs new bearings, lip seal, and filter Cajah’s Mountain Superette November 1, 2017 Corrective Action Performance Report Page 6 media. Costs for these repairs were approved by the NCDEQ on March 8, 2017. The blower will be reinstalled following repairs. SVE influent air samples are collected on a quarterly basis during system operation to identify the efficiency of the SVE systems and assist with system optimization efforts. An SVE influent air sample was collected from the on-site system on March 14, 2017, and was submitted to Prism Laboratories, Inc. for analysis by EPA Method 18. The laboratory analytical report is provided in Appendix A. Table 6 shows SVE cumulative recovery calculations based on system influent sampling data. Based on laboratory analytical results from quarterly influent air sampling, approximately 1,311 and 41.53 pounds of total BTEX have been recovered by the on-site and off-site SVE systems, respectively, since startup. The on-site and off-site system influent total BTEX concentrations upon initial startup and sampling in April 2014 were 413 mg/m3 and 0.64 mg/m3, respectively. The influent total BTEX concentrations during the most recent sampling were 290 mg/m3 and 42.4 mg/m3 for the on-site and off-site systems. Free product has historically been identified in on-site well MW-8 at a maximum thickness of 2.97 feet. Following multiple AFVR events and adsorbent sock changeouts, the well has not indicated free product since 2015. Groundwater contamination above NCDEQ 2L Standards is generally located in front of the on-site building in the vicinity of the former UST system and migrates downgradient to the east-southeast across Connelly Springs Road towards well IMW-1 and slightly to the southwest towards wells MW-9 and DMW-2. Contaminant concentrations in the source area generally indicate a decreasing trend with time, though some rebounding was observed in December 2016. 4.0 CONCLUSIONS AND RECOMMENDATIONS The AS/SVE systems were started at the site in March and April 2014, and dissolved contaminant concentrations generally indicate a decreasing trend system system startup. However, a groundwater monitoring event, conducted in December 2016, indicated recent groundwater contaminant increases. System downtime during the monitoring event may be attributable to the contaminant increases. Free product was not observed in gauged wells in December 2016. Impact concentrations in intermediate and deep wells appear generally stable or are decreasing. ATC recommends continued AS/SVE system operation and maintenance (O&M) visits and site groundwater monitoring at the Cajah’s Mountain Superette site. System O&M visits should continue to be conducted Cajah’s Mountain Superette November 1, 2017 Corrective Action Performance Report Page 7 twice per month and continued efforts to optimize system efficacy should be implemented. Quarterly SVE effluent air sampling is recommended during scheduled O&M visits. ATC recommends groundwater monitoring events be conducted on a semi-annual basis during winter and summer months. 5.0 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. Subsurface investigative and remedial methodologies were performed in general accordance with applicable state and federal regulatory requirements. The information presented in this report is based upon site-specific observations, generally accepted geological and environmental consulting practices, and analytical results for environmental samples collected at the time of the field investigation was performed. The data presented in this report are believed to represent subsurface conditions at the facility; however, data may not be completely representative of subsurface conditions at every location. ATC assumes no liability arising from environmental impact to, or from, the site, regardless of the date of impact occurrence or findings.

(ATC) to prepare a Corrective Action Performance Report for the project site located at 1990 Connelly Springs Road in Lenoir, Caldwell County, North Carolina. Figure 1 shows the site and vicinity on part of a United States Geological Survey (USGS) site topographic map. A map showing site details is provided as Figure 2. This report documents three months of remedial system operation and maintenance. Groundwater impact at the site has historically been identified at concentrations exceeding Gross Contamination Levels (GCLs). Generally decreasing trends have been observed over time. However, according to groundwater analytical results obtained from a monitoring event performed in December 2016, contaminant concentrations increased, and benzene was reported in well MW-8 at a concentration above the GCL. The remedial systems were not operational during the December 2016 groundwater monitoring event and that may be the reason for observed increased dissolved impact. The remedial systems were restarted on July 10, 2017, and a subsequent groundwater monitoring event conducted on July 18 and 19, 2017, indicated stabilized or reduced contaminant concentrations. Petroleum hydrocarbons were detected above the associated 15A NCAC 2L .0202 Standards (2L Standards) in eight of the 11 sampled site monitoring wells in July 2017. Historical groundwater sampling results are provided in Table 3. Free product has historically been identified in site well MW-8 at a maximum thickness of 2.97 feet. Free product was not identified in site monitoring wells in July 2017. As outlined in the October 31, 2012, Corrective Action Plan (CAP), high vacuum extraction through the implementation of Aggressive Fluid/Vapor Recovery (AFVR) technology appeared to be the most feasible and cost effective option for recovering remaining free product from on-site well MW-8. AFVR events were conducted between March 2012 and December 2013 and recovered approximately 44 gallons of liquid phase product, 54.17 gallons of vaporized product, and 1,870 gallons of petroleum-contact water from well MW-8. Historical free product recovery information is summarized in Table 4. Adsorbent socks were installed and changed as necessary in well MW-8 beginning in February 2015 to recover remaining free product. The socks were removed in early July 2015, and the well has not indicated free product during subsequent groundwater monitoring events. Natural attenuation was determined in the CAP to be the most feasible and cost effective remedial option for reducing groundwater contaminant concentrations in the intermediate and deep aquifer zones. Historical Cajah’s Mountain Superette December 18, 2017 Corrective Action Performance Report Page 2 natural attenuation sampling indicates an environment conducive to potential bioremediation in the intermediate and deep aquifer zones. Generally, measured dissolved oxygen concentrations are consistently above anoxic and hypoxic conditions, indicating a potential for aerobic activity. Dissolved oxygen concentrations in wells IMW-1 and DMW-1 tend to be particularly high. Natural attenuation parameters are presented in Table 5. Petroleum compound concentrations had generally shown an increasing trend in downgradient, intermediate well IMW-1, until January 2016 when concentrations began decreasing. Some contaminant concentration rebounding was observed in well IMW-1 in December 2016, but the increases may have been due to off-site system downtime. The system was restarted on July 10, 2017, and a monitoring event conducted on July 18 and 19, 2017, generally indicated stabilized impact concentrations. Impact in this well will continue to be monitored and remedial system adjustments should be made as deemed necessary. Impact in on-site, deep well DMW-1 is generally decreasing with time. Contaminants of concern in other intermediate and deep wells remain minimal. The CAP identified air sparge/soil vapor extraction (AS/SVE) as the chosen corrective action technologies for shallow petroleum-impacted groundwater at the site. Air sparge and soil vapor extraction wells were installed at the site on December 30, 2013, through January 15, 2014. The on-site and off-site system installations were completed on January 13, 2014, through January 24, 2014. System startup activities were conducted on March 26, 2014. However, due to noise concerns, the off-site system was turned off until April 9, 2014, when the telemetry was programmed to operate the system from 8:00 am to 8:00 pm. Based on impact to vicinity water supply wells and historical free product and groundwater impact in site monitoring wells, the risk classification for the site has been designated as “High” and ranked H190D by the North Carolina Department of Environmental Quality (NCDEQ). Therefore, groundwater contamination must be remediated to concentrations which are equal to or less than the associated 2L Standards. 2.0 SUPPORTING INFORMATION AND CAP IMPLEMENTATION An underground storage tank (UST) system consisting of three tanks was formerly located on-site and was operated by Cary Oil from April 2005 until August 2008 when the UST system was removed. During UST removals, soil impact was identified and led to assessment requests from the North Carolina Department of Environment and Natural Resources (NCDENR; currently the NCDEQ). Cajah’s Mountain Superette December 18, 2017 Corrective Action Performance Report Page 3 The subject property is owned by Mary Lindsay and has one building that currently operates as a catering business known as Mooresridge Catering. The site formerly operated as a convenience store which included a UST system consisting of two 8,000-gallon gasoline USTs and one 4,000-gallon gasoline UST. Site history including on-site UST system information is summarized in Table 1. A site plan that indicates monitoring well locations and other site features is provided as Figure 2. The perennial surface water body identified in the closest proximity to the site is Stafford Creek located approximately 2,000 feet to the southwest of the site. A branch of Little Gunpowder Creek lies approximately 2,500 feet to the east of the site. The Caldwell County Geographic Information System database identified surface water bodies towards the east and west at distances of 700 and 500 feet from the site, respectively; however, these surface water bodies were not identified during field activities. Surface cover at the site consists mostly of asphalt on the east side of the property and grass and gravel on the west side of the property. The site lies in the Inner Piedmont in an area characterized by inter-fingered biotite gneiss, biotite schist, and mica schist with some other minor rock types that are heavily metamorphosed and structurally complex. The shallow subsurface contains overburden of soil, saprolite, and partially weathered rock (PWR) that derive from in-place weathering. Findings from the Comprehensive Site Assessment (CSA) suggest that most of the unconsolidated subsurface materials exhibit high permeability for the Piedmont and probably can best be described as saprolite or PWR. During assessment activities, rock was encountered at decreasing depths with distance from the site towards the east, with depths ranging from 85 feet below ground surface (bgs) at on-site well DMW-3 to 20 feet bgs at downgradient well MW-21. Depth to groundwater in the site monitoring wells ranged from approximately 23 to 35 feet below top of casing (TOC) during the July 2017 groundwater sampling event. Based on the recent groundwater level measurements and calculation of groundwater elevations, groundwater flows generally towards the southeast across the site. Baton Water Corporation and the Town of Lenoir supply public water in the site vicinity. Twenty-one (21) private water supply wells have been identified within approximately 1,500 feet of the site. Water supply well information for the area is summarized in Table 2, and supply well locations relative to the source area are depicted on Figure 3. Between 2008 and 2012, site assessment, AFVR events for free product recovery, and a CAP with pilot Cajah’s Mountain Superette December 18, 2017 Corrective Action Performance Report Page 4 testing were conducted related to the Cajah’s Mountain Superette release. Free product recovery efforts in the form of AFVR events, conducted between 2012 and 2013 recovered approximately 44 gallons of liquid phase product, 54.17 gallons of vaporized product, and 1,870 gallons of petroleum-contact water from well MW-8. Historical free product recovery information is summarized in Table 4. Adsorbent socks were installed and changed as necessary in well MW-8 between February 2015 and July 2015, and the well has not indicated free product during subsequent groundwater monitoring events. Based on results of the CAP and pilot testing, ATC found that AS and SVE technologies appeared to be the most feasible and cost effective remedial options for reducing groundwater contaminant concentrations in the shallow aquifer, and monitored natural attenuation was chosen for groundwater in the intermediate and deep zones. The AS/SVE wells were installed from December 30, 2013, to January 15, 2014. Depths of the air sparge wells ranged from 50 feet to 95 feet bgs, depending on zones of groundwater impact and depth of bedrock. Wells SVE-2 through SVE-7 and SVE-10 through SVE-14 were installed to depths of 34 feet or 35 feet bgs, depending on vicinity groundwater levels. Wells SVE-8 and SVE-9 were installed to depths of 26 feet bgs due to the elevated water table encountered behind the on-site building. Vapor extraction well SVE-1 was installed to a depth of 35 feet bgs on August 22, 2012, for the pilot study. The systems were installed during the period of December 2013 through January 2014. The on-site and off- site air sparge systems consist of six and eight air sparge wells, respectively, rotary claw air compressors, and schedule 80 PVC piping for transferring compressed air from the remediation systems to the air sparge wells. The on-site and off-site vapor extraction systems consist of nine and five vapor extraction wells, respectively, regenerative vacuum blowers, condensate collection vessels, and schedule 40 PVC piping for transferring extracted vapors from the vapor extraction wells to the remediation systems. A system design drawing is included as Figure 4. 3.0 GROUNDWATER REMEDIATION 3.1 Background System startup activities were conducted on March 26, 2014. However, due to noise concerns, the off-site system was turned off until April 9, 2014, when the telemetry could be programmed to operate the system from 8:00 am to 8:00 pm. Efforts have been made to reduce excessive noise that originates from the building but minimal reductions have been observed. Cajah’s Mountain Superette December 18, 2017 Corrective Action Performance Report Page 5 Air sparge wells AS-1 through AS-3 were left off, by means of closed system manifold valves, until free product was sufficiently recovered from the area. Following a reduction in measurable product at the site, sparge wells AS-1 through AS-3 were started in October 2015. Off-site wells AS-10 and AS-11 were shut down on April 13, 2016, and wells AS-9 and AS-12 were shut down on April 28, 2016, to provide more sparge pressure to the west side of the off-site property where higher dissolved contaminant concentrations exist. On-site system downtime has historically often been attributable to high temperature alarms which shut the system down during summer months, and power losses following storms. Off-site system downtime in 2014 occurred due to bad motor windings on the SVE blower which shut the system down. The off-site SVE blower was replaced under warranty by the system fabricator on October 15, 2014. Electrical issues (power outages, phase losses, and an indicated electrical fault) occurred at both the on-site and off-site systems in 2015. The systems were ultimately shut down manually by ATC as a safety precaution. The issue was identified to be melted high voltage fuses in each system which led the systems to run on one phase and then shut down. A small fire at the on-site catering business building occurred in August 2015, which Duke Energy attributed to insufficiently sized wires for the load. The wires were subsequently changed by Duke Energy. The combined issues are potentially related to a general electrical issue in the area, possibly caused by recent electrical storms. High voltage fuses on the on-site and off-site SVE blowers were replaced in October 2015 and the systems were re-started. Due to frequent shutdowns, the off-site SVE blower vacuum was reduced in 2016 as it was determined the operating capacity of the unit could not be fully achieved in the actual operating conditions. That is to say, the potential capacity of the blower is assumed under ideal conditions which are rarely achieved in an environmental, non-climate controlled setting. 3.2 System Operation and Maintenance, May-July 2017 System operation and maintenance was conducted twice per month from May to July 2017 to check system components and perform routine maintenance. Efforts are made to combine site visits with visits conducted at another Cary Oil site in the vicinity, Tilley’s Superette. On-site system run-time was approximately 89% from May to July 2017. System downtime was due to a phase fault from storms in the area during the Cajah’s Mountain Superette December 18, 2017 Corrective Action Performance Report Page 6 reporting period. Vacuum readings for each well point at the on-site SVE manifold were set at approximately 38 inches of water. Pressure readings for each well point at the on-site AS manifold were set at approximately 10 pounds per square inch (psi). The off-site system was not operational from December 2016 to July 10, 2017, due to a power fault which resulted in burned SVE motor wires. Additionally, a local motor repair shop assessed the blower motor and identified the following: one endbell needed to be bushed and the motor needed new bearings, lip seal, and filter media. Repairs were completed in June 2017 and the blower was re- installed at the site. Upon off-site system restart, a grinding noise was heard at the SVE blower. The motor repair shop assessed the problem and shaved the fan blades to prevent them from rubbing together. The system was fully restarted on July 10, 2017. During off-site system operation in July 2017, vacuum readings for each well point were set at approximately 22 inches of water. Pressure readings for each well point at the off-site AS manifold were set at approximately six psi. Off-site wells AS-9, AS-10, and AS-11 were left off to provide more sparge pressure near well IMW-1 and to the west side of the off-site property where higher dissolved contaminant concentrations exist. SVE influent air samples are collected on a quarterly basis during system operation to identify the efficiency of the SVE systems and assist with system optimization efforts. An SVE influent air sample was collected from the on-site system on June 20, 2017, and was submitted to Prism Laboratories, Inc. for analysis by EPA Method 18. The laboratory analytical report is provided in Appendix A. A sample was not collected from the off-site system following the July 2017 restart. Table 6 shows SVE cumulative recovery calculations based on system influent sampling data. Based on laboratory analytical results from quarterly influent air sampling, approximately 1,466 and 41.53 pounds of total BTEX have been recovered by the on-site and off-site SVE systems, respectively, since startup. The on-site and off-site system influent total BTEX concentrations upon initial startup and sampling in April 2014 were 413 mg/m3 and 0.64 mg/m3, respectively. The influent total BTEX concentrations during the most recent sampling were 208 mg/m3 and 42.4 mg/m3 for the on-site and off-site systems. Free product has historically been identified in on-site well MW-8 at a maximum thickness of 2.97 feet. Following multiple AFVR events and adsorbent sock changeouts, the well has not indicated free product since 2015. Groundwater contamination above NCDEQ 2L Standards is generally located in front of the on-site building in the vicinity of the former UST system and migrates downgradient to the east-southeast across Connelly Springs Road towards well IMW-1. Contaminant concentrations in the source area and downgradient generally indicate a decreasing trend with time. Cajah’s Mountain Superette December 18, 2017 Corrective Action Performance Report Page 7 4.0 CONCLUSIONS AND RECOMMENDATIONS The AS/SVE systems were started at the site in March and April 2014, and dissolved contaminant concentrations generally indicate a decreasing trend since system startup. Groundwater contaminant increases are generally observed during system downtime. Free product was not observed in gauged wells in July 2017. Impact concentrations in intermediate and deep wells appear generally stable or are decreasing. ATC recommends continued AS/SVE system operation and maintenance (O&M) visits and site groundwater monitoring at the Cajah’s Mountain Superette site. System O&M visits should continue to be conducted twice per month and continued efforts to optimize system efficacy should be implemented. Quarterly SVE effluent air sampling is recommended during scheduled O&M visits. ATC recommends groundwater monitoring events be conducted on a semi-annual basis during winter and summer months. 5.0 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. Subsurface investigative and remedial methodologies were performed in general accordance with applicable state and federal regulatory requirements. The information presented in this report is based upon site-specific observations, generally accepted geological and environmental consulting practices, and analytical results for environmental samples collected at the time of the field investigation was performed. The data presented in this report are believed to represent subsurface conditions at the facility; however, data may not be completely representative of subsurface conditions at every location.
