Samples collected during closure activities by Wallace-Lee Consultants, llC (WLC) revealed elevated levels of hydrocarbons. An lSA Report was completed by WLC in April 2000 with an LSA Addendum completed by WlC In December 2000, which concluded that groundwater at the site contained constituents levels exceeding both NCAC 2l standards and GCls. During LSA activities conducted by WlC, free phase LNAPL was discovered at the site in monitoring well MW-2. Free product recovery efforts reportedly began in February 2000 by monthly site visits for liquid level gauging and hand bailing. To date, eight Aggressive Fluid Vapor Recovery (AFVR) and two 100-hour Mobile Multi-Phase Extraction (MMPE) events have previously been conducted at the site by WLC. A vacuum enhanced free product recovery system was installed The subject site is located in the Milton Belts of the Inner Piedmont Geologic Physiographic Province. The 1985 USGS Geologic Map of North Carolina Indicates that rock in this area is commonly characterized by inequigranular and megacrystic biotite gneiss and schist.

As proposed in the revised Corrective Action Plan completed by Excel dated March 23, 2013, the onsite remediation system was placed into operation in January of 2015 . The vacuum enhanced free product recovery system is comprised of two vapor extraction wells and two free product skimmer pumps. A summary of the field activities associated with the monthly operation and maintenance is given in subsequent sections of this report. Operation of the remediation system has resulted in a reduction of lNAPL in MW-2 from a maximum thickness of 0.44 feet measured in April of 2015 to a current thickness of 0.17 feel during Ihe reporting period. LNAPL in MW-4 is observed to have remained at a thickness of 0.02 feet (refer to Table 1 and Figure 4). The goal of the remediation system is to eliminate free product utilizing vacuum enhanced pneumatic skimmers within the source area. The stated milestone of removing free product has not yet been completed and has been delayed due to property accessibility issues caused by the current property owner. Based upon a review of the current analytical data from March 2017, the estimated size of the area of elevated benzene and MTBE exceeding GCl Standards is approximately 3,900 and 7,500 square feet (MTBE plume), primarily located on the subject property and spanning beneath the former crown building south to the former UST tank pit. Results of past receptor surveys completed by Excel during assessment activities indicate that supply wells were not identified within 1,500 feet of the property. Additionally, according to the USGS Topographical Map no surface water bodies are located within 1,500 feet of the source area. SITE HISTORY The (former) Servco No. 0171 1 facility is located at 850 North Liberty Street within the city of Winston-Salem, Forsyth County, North Carolina (refer to Figure 1). A site map of the facility detailing former structures and monitoring well locations is provided as Figure 2. Various assessment activities have been conducted at the (former) Servco No. 0171 1 facility following UST Closure Assessment activities conducted by Service Distributing Company, Incorporated (Servco) in August 1999 completed by Wallace-Lee Consultants, LLC (WLC) of Wilmington, North Carolina. During the assessment activities, seven regulated UST's were removed as part of one excavation during the closure activities. Following removal of the USTs, reportedly no additional soils were excavated with excavated soils returned to the UST basin. A total of 32 soil samples were collected from the UST basins, beneath the product lines and dispenser islands and analyzed for Total Petroleum Hydrocarbons (TPH) by EPA Methods 5030 and 3550 (Gasoline and Diesel Range OrganiCS, respectively). Based on review of the report submitted to the NCDEQ on August 17. 1999, analytical results revealed elevated levels of petroleum hydrocarbons in multiple soil samples collected from beneath the UST system. At the request of the North Carolina Department of Environmental Quality (NCDEQ). Winston- Salem Regional Office (WsRO), Division of Waste Management, UST Section, a LSA was EXCEL CtVIL & ENVIRONMENTAL AsSOCIATES, PLlC www.excelengr.com Monitoring Report (Former) Servco No. 01711 Winston-Salem, North Carolina July 11, 2017 Incident No. 20966 Excel No. 24090 completed for the subject property. Servco contracted Wl C to complete the LSA, which included the installation of five Type II monitoring wells, a potable well survey, soil and groundwater sampling with associated laboratory analysis and the completion of the LSA report. The soil samples collected at the location of MW-1 were found to be above the Soil-Io-Water Maximum Soil Contaminant Concentrations (MSCC) for various constituents as detailed in the January 2, 1998 Groundwater Section Guidelines as amended. None of the samples collected revealed hydrocarbon levels above applicable Industrial/Commercial MSCCs. The laboratory results of the groundwater samples collected from MW-1, MW-3 and MW-4 were found to exceed Gross Contam ination levels (GCLs) for benzene as detailed in the January 2, 1998 Groundwater Section Guidelines as amended. During the LSA activities, free product was encountered in monitoring well MW-2 with a measured thickness of approximately 2.64-feel. To date, Excel and others have conducted multiple free product recovery events incorporating both aggressive and passive techniques since February 2000. Eight Aggressive Fluid-Vapor Recovery (AFVR) events were conducted by WLC reportedly yielding a collective approximate 315-gallons of product. In addition, WLC conducted two 100-hour Mobile Multi-Phase Extraction (MMPE) events and Excel completed one 100-hour MMPE event recovering a total of 830- gallons of producUwater mixture from the location of MW-2. At the request of the NCDEQ, a Free Product Recovery Specification Report was completed by Excel on April 15, 2010. Activities included the installation of two additional monitoring wells MW-6 and MW-7 and the completion of a free product evaluation at the location of MW-2. Results of the field evaluation revealed no free product in the newly installed monitoring wells and that the true free product thickness at MW-2 was measured at 0.04-feet with an expected recovery rate of O.4-gallons per hour, Excel recommended the implementation of a free product recovery system at the site. As directed by the NCDEQ, one additional downgradient monitoring well (MW-13) and two vapor extraction wells (SVE-1 and SVE-2) were installed on November 24,2014. Replacement monitoring well MW-2R was installed January 15, 20 15. The onsite remediation system, utilizing vacuum enhanced free product recovery was placed into operation in Ja nuary of 2015. The soil vapor extraction system is comprised of two vapor extraction wells. A summary of the field activities associated wi th the monthly operation and maintenance is given in subsequent sections of this report. Site access was denied to ECEA by the property owner in June of 2016 and ECEA was not granted access to return to the property until March of 2017. During the interim, the free product recovery system maintenance could not be completed. The lack of site access has delayed site cleanup activities by the responsible party. Cleanup levels (soil) for the site would be the lesser of the Industrial/Commercial Maximum Soil Contaminant Concentrations (MSCCs) or the Soil-la-Water Maximum Soil Contaminant Concentrations (MSCCs). This CAP proposed the res tora tion of groundwater quality to a site- specific aclion levels approximating Gross Contamination Levels (GCls) for the applicable standards developed for this site. Following achievement of the site-specific action level, the site risk classification can be reduced to "Low" and active grou ndwater remediation can be EXCEl CIVil & ENVIRONMENTAL ASSOCIATES, PllC www.excelengr.com Monitoring Report July 11 , 2017 Incident No. 20966 Excel No. 24090 (Former) Servco No. 01711 Win ston-Salem, North Carolina suspended. Once risk reduction has occurred, the applicable soil cleanup levels for the site wou ld be Industrial/Commercial. CURRENT ASSESSMENT INFORMATION • • • • • • Groundwater quality samples were collected from eight monitor wells on March 24, 2017 and laboratory analyzed for full range volatile organic compounds (VOCs) by EPA Method 6200B. It is Excel's standard operating procedure not to gauge monitoring wells with an oil· water interface probe prior to sampling if said well has not historically shown free product. Static water levels were collected with a decontaminated water level indicator at locations where free product has not previously been encountered. Groundwater quality samples were collected from monitoring wells MW-1, MW-6, MW-7, MW-8, MW-9, MW-10, MW-11, and MW-13 on March 24, 2017. Monitoring wells MW-2R and MW-4 were not sampled due to the presence of free product: monitoring wells MW-3, MW-5 and MW-12 could not be located. A map depicting the estimated extent of free product is provided as Figure 4. The results of the laboratory data for the groundwater samples collected were compared against the Gross Contamination levels (GCls). The analytical data presented for the constituents detected was determined based on the highest result from the various EPA Methods described above. A review of the laboratory analytical results indicated the following constituents were above applicable regulatory standards: > Benzene • GCl: MW-1 and MW-7 ~ Methyl-tert-butyl-ether (MTBE) • GCl: MW-1, MW-6 and MW-7 Based upon a review of the current analytical data, the estimated size of the area of elevated benzene and MTBE exceeding GCl Standards is approximately 3,900 and 7,500 square feet (MTBE plume), primarily located on the subject property and spanning beneath the former crown building south to th e former UST tank pit. The elevated benzene and MTBE levels exceeding NCAC 2l levels were observed to be spanning offsite onto the adjacent properties to the south and east. The remaining constituents are a minor portion of the benzene and MTBE plumes. Some seasonal fluctuations were observed in the groundwater quality data from select wells. The onsite remediation system was placed into operation in January of 2015. The soil vapor extraction system is comprised of two vapor extraction wells. A summary of the field activities associated with the monthly operation and maintenance is given in subsequent sections of this report. A copy of the system maintenance form is included in Appendix D. Soil samples were collected at the site from four soil boring locations, in accordance with an agreement with the property owner. Soil samples were collected at depths ranging from 3- fbgl to B-fbgl on March 24, 2017. Table 4 summarizes the soil results from the onsite samples collected during the current assessment activities conducted by Excel. Soil EXCEL CIVIL & ENVIRONMENTAL ASSOCIATES, Pll C www.excetengr.com Monitoring Report (Former) Servco No. 01711 Winston-Salem, North Carolina July 11, 2017 Incident No. 20966 Excel No. 24090 samples were collected in laboratory provided containers and analyzed by Environmental Science Corporation of Mt. Juliet, Tennessee for the following parameters: Volatile Organics by EPA Method 8260; Semivolatile Organics by EPA Method 8270; Total Petroleum Hydrocarbons, Diesel Range Organics by EPA Method 5030; and MADEP Volatile Petroleum Hydrocarbons (VPH). A review of soils data collected by Excel during the March 2017 sampling event does not indicate impacted soil levels which exceed Industrial/Commercial MSCCs. Figure 6 in Appendix B depicts select groundwater constituents. A complete copy of the laboratory analytical data is located in Appendix B. • Based on the liquid level data collected, groundwater flow is estimated to be to the south. A groundwater contour map is included in Appendix B, Figure 3. • Results of past receptor surveys completed by Excel during assessment activities indicate that supply wells were not identified within 1,500 feet of the property. Additionally, according to the USGS Topographical Map no surface water bodies are located within 1,500 feet of the source area. FREE PRODUCT REMOVAL • Based upon a review of the current analytical data, the estimated size of the LNAPL is approximately 500 square feet, primarily located to the south of the former Crown building. • Operation of the remediation system has resulted in a reduction of LNAPL in MW-2 from a maximum thickness of 0.44 feet measured in April of 2015 to a current thickness of 0.17 feet during the report ing period. LNAPL in MW-4 is observed to have remained at a thickness of 0.02 feet (refer to Table 1 and Figure 4). The free product collection tank was recorded to contain approximately 12.53 gallons of producUwater mix on May 30, 2017. CONCLUSIONS & RECOMMENDATIONS • In summary, current laboratory analytical data indicates that overall dissolved phase hydrocarbon constituents (primarily BTEX and MTBE) continues to occur at the site and are decreasing with some seasonal fluctuations. Remaining cons tituent levels exceed the GCL and NCAC 2L Standards at multiple locations for various constituents. • Mann-Kendall graphs are provided in Appendix A. The graphs showing concentration trends for Monitoring Wells MW-1, MW-3, MW-6, MW-7 and MW-8. The concentration trends for benzene and MTBE show decreasing or no trend for all wells with the exception of MW-7. MW-7 is located adjacent to the LNAPL and should begin to decrease once the free product has been removed from that area. • At this time and based on the information in this report, we recommend continued operation of the vacuum enhanced free product recovery, free product recovery efforts at monitoring wells MW-2R and MW-4, and continuing semiannu al groundwater sampling of select wells.

ND Not detected at the Reporting Limit (or MDL where applicable). U Not detected at the Reporting Limit (or MDL where applicable). RPD Relative Percent Difference. (dry)Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils]. Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control sample. The Original Sample may not be included within the reported SDG. (S)Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media. Rec.Recovery. Qualifier Description B The same analyte is found in the associated blank. E The analyte concentration exceeds the upper limit of the calibration range of the instrument established by the initial calibration (ICAL). J The identification of the analyte is acceptable; the reported value is an estimate. J1 Surrogate recovery limits have been exceeded; values are outside upper control limits. J3 The associated batch QC was outside the established quality control range for precision. J4 The associated batch QC was outside the established quality control range for accuracy. J5 The sample matrix interfered with the ability to make any accurate determination; spike value is high. J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low. J7 Surrogate recovery cannot be used for control limit evaluation due to dilution. V3 The internal standard exhibited poor recovery due to sample matrix interference. The analytical results will be biased high. BDL results will be unaffected. 1 Cp 2Tc 3Ss 4Cn 5Sr 6Qc 7Gl 8Al 9Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Excel Civil & Environmental Associates 24090 L898293 04/07/17 09:00 59 of 62 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Excel Civil & Environmental Associates 24090 L898293 04/07/17 10:15 59 of 62 ONE LAB.
