EXECUTIVE SUMMARY The purpose of this report is to evaluate the current status of the groundwater quality at the Arlington Branco Oil Company site (Incident No. 30114). The site is a former bulk petroleum facility and gasoline filling station located at 270 North Main Street in Jonesville, North Carolina. The property, comprised of approximately 0.92 acres, contains an approximate 1,646 sq. ft. vehicle repair shop that operates as Jordan’s Pit Stop. A separate garage/shed structure and mechanic’s pit are located to the west of the vehicle repair shop. Several inactive aboveground petroleum storage tanks from past bulk petroleum operations are located in the northeastern portion of the site. Jonesville Creek is located on the adjacent property to the west of the site. Reportedly, eight former on-site USTs were removed in the early 1990s. Analytical results of soil sampling conducted beneath the former USTs indicated a petroleum release at the site in 1994. At the direction of the NCDEQ, Terracon mobilized to the site on January 8, 2016 to sample the groundwater from six monitoring wells (MW-1 through MW-6), the on-site water supply well (WSW- 1), and surface water from Jonesville Creek. Depth to groundwater in monitoring wells (MW-1, MW- 3, MW-4, MW-5 and MW-6) ranged from approximately 12.16 to 14.64 feet below ground surface (bgs). Terracon measured a free product thickness of 0.02 feet in monitoring well MW-6. Terracon was unable to open well MW-2. The estimated groundwater flow direction is to the southwest towards Jonesville Creek. Following well development, groundwater samples were collected from each well, placed in laboratory provided containers and delivered to Pace Analytical Services, Inc. in Huntersville, North Carolina for analysis of volatile organic compounds (VOCs) by Standard Method 6200, including methyl tert-butyl ether (MTBE), ethylene dibromide (EDB) and diisopropyl ether (IPE). Laboratory results indicated various petroleum constituents were detected in the monitoring wells at the site. Benzene, 1,2-dichloroethane, IPE, ethylbenzene, isopropylbenzene, MTBE, naphthalene, n- propylbenzene, 1,2,4-trimethylbenzene, 1,3,5-trimethylbenzene, and xylenes were detected at concentrations above their respective 2L groundwater standards in the on-site wells. Recent analytical data compared to historical data seem to display an overall decreasing trend for most of the detected constituents; however, in certain wells, some constituents are static or concentrations have increased. Arlington Branco Oil Company Jonesville, North Carolina Terracon Project No. 71149678 Incident No. 30114 February 11, 2016 Responsive ■Resourceful ■Reliable 3 Based on information obtained during the completion of our assessment activities, Terracon provides the following conclusions and findings. Multiple petroleum constituents were detected in wells MW-1, MW-3 and MW-5 at concentrations that exceed their respective 15A NCAC 2L groundwater standards. Other petroleum constituents were detected in the on-site wells but at concentrations below their respective 2L groundwater standards. None of the detected petroleum constituents exceed Gross Contaminant Levels (GCLs). Groundwater monitoring well MW-6 contained 0.02 feet of free product. The well was not sampled. The estimated groundwater flow direction is to the southwest towards Jonesville Creek. Petroleum constituents were not detected in Jonesville Creek above 2B surface water standards. Benzene, naphthalene, n-Propylbenzene and 1,2,4-trimethylbenzene were detected in on-site water supply well WSW-1 at concentrations above their respective 2L standards. Multiple other petroleum constituents were detected in well WSW-1 but at concentrations below their respective 2L groundwater standards. Well WSW-1 is not currently in use as a source of potable water. Based on the data presented in this Pre-Cap Monitoring report, Terracon recommends the following activities be completed at the site. Sample on-site groundwater monitoring wells (MW-1 through MW-6) and Jonesville Creek semi- annually to evaluate the status of impact by petroleum constituents. Terracon recommends the placement of “Bio Socks” into the monitoring wells MW-1, MW-2, and MW-3 to reduce the concentrations of dissolved-phase petroleum constituents in the well semi- annually. Terracon recommends the placement of an absorbent well sock into monitoring well MW-6 to remove the free product. C. SITE HISTORY AND CHARACTERIZATION The purpose of this report is to evaluate the current status of the groundwater quality at the Arlington Branco Oil Company site located at 270 North Main Street in Jonesville, Yadkin County, North Carolina (Figure 1). Terracon completed this report to summarize the findings of assessment activities performed on January 8, 2016. This Pre-Cap Monitoring report was prepared for the site in response to a request by the Incident Manager, Mr. Herb Berger with the NCDEQ Division of Waste Management, State Lead Program. The Pre-Cap Monitoring Report was prepared in general accordance with 15A NCAC 2L .0115 regulations and the NCDEQ Underground Storage Tank (UST) Section Guidelines for Assessment and Corrective Action for UST Releases, dated July 15, 2008, revised December 2013, under the supervision of Mr. Christopher L. Corbitt, a North Carolina registered licensed geologist (North Arlington Branco Oil Company Jonesville, North Carolina Terracon Project No. 71149678 Incident No. 30114 February 11, 2016 Responsive ■Resourceful ■Reliable 4 Carolina License No. 1015). C.1 Site Setting The site is a former bulk petroleum facility and gasoline filling station located at 270 North Main Street in Jonesville, North Carolina. The property, comprised of approximately 0.92 acres, contains an approximate 1,646 sq. ft. vehicle repair shop that operates as Jordan’s Pit Stop. A separate garage/shed structure and mechanic’s pit are located to the west of the vehicle repair shop. Several inactive aboveground petroleum storage tanks from past bulk petroleum operations are located in the northeastern portion of the site. Jonesville Creek is located on the adjacent property to the west of the site. The site is depicted in Figure 2. The site is bound to the southwest by Main Street (U.S. Highway 21); to the southeast and east by Dogwood Street; and to the west and northwest by Jonesville Creek. Properties to the north and east are occupied by residences while properties to the south and west are occupied by commercial businesses and residences. C.2 Release Summary According to a UST closure report completed in January 2003 by GeoScience & Technology, P.A., eight USTs were removed from the site in the early 1990s by Haynes Engineering Associates. Soil sampling by Haynes Engineering Associates (1994) and GeoScience & Technology, P.A. (2002) discovered petroleum impacts at the locations of the former USTs, the dispenser islands and product lines. A chronological summary of petroleum releases and assessment activities at the site is included in the following section of the report. C.3 Previous Investigations A UST Closure Report prepared by GeoScience & Technology, P.A. dated January 2003 indicates eight on-site USTs were removed in December 1992 and December 1993 by Haynes Engineering. The eight USTs consisted of two 6,000-gallon gasoline USTs, one 4,000-gallon gasoline UST, one 3,000-gallon gasoline UST, one 2,000-gallon gasoline UST, one 1,000-gallon waste oil UST, one 550-gallon kerosene UST, and one 550-gallon fuel oil UST. There are no reported records of soil sampling conducted during the removal of the USTs; however, Haynes Engineering reportedly conducted soil sampling at the site in 1994. The soil samples collected in 1994 indicated petroleum impacts at the locations of the former USTs. GeoScience & Technology, P.A. collected soil samples in 2002 to complete the UST closure report. Laboratory results from the 2002 sampling event indicated petroleum constituents were detected near the dispenser islands and product lines. A Groundwater Sampling and Receptor Survey Report dated January 10, 2006, prepared by Schnabel Engineering South (Schnabel) references an incomplete Limited Site Assessment (LSA) in 2003 by GeoScience & Technology, P.A. Reportedly, GeoScience & Technology, P.A. installed two monitoring wells on the site and sampled the on-site water supply well (WSW-1). Analytical results Arlington Branco Oil Company Jonesville, North Carolina Terracon Project No. 71149678 Incident No. 30114 February 11, 2016 Responsive ■Resourceful ■Reliable 5 indicated petroleum constituents were detected above their respective 2L standards in the monitoring wells and six inches of free product was measured in well WSW-1. Schnabel also referenced a groundwater sampling event conducted by Force Environmental Service Company, LLC (Force) in 2005 that reported 3.8 feet of free product was measured in well MW-2. Reportedly, Force detected benzene above its GCL and multiple other petroleum constituents above their respective 2L standards in well MW-1. Naphthalene and 1,2,4-trimethylbenzene were detected above their GCLs and sec-butylbenzene, 1,3,5-trimethylbenzene, and xylenes were detected above their respective 2L standards in well WSW-1. Schnabel also conducted a receptor survey and identified eleven water supply wells within a 1,500-foot radius of the source area. Schnabel also noted that municipal water is available to the site area. In a Monitoring Well Installation, Groundwater and Water Supply Well Sampling Report dated October 2006, Schnabel reportedly installed four additional monitoring wells (MW-3, MW-4, MW-5 and MW-6) at the site. According to the report, soil samples from borings MW-4, MW-5 and MW-6 exceeded the regulatory action level for TPH-DRO. Schnabel also reported various petroleum constituents were detected above the 2L standards in wells MW-1, MW-3, MW-5, and MW-6, and free product was measured in wells MW-2 [0.45 feet] and WSW-1 [0.73 feet in August 2006 and 1.06 feet in September 2006]. Schnabel also sampled Jonesville Creek and off-site water supply wells WSW-6 and WSW-7. Benzene was detected in well WSW-6 at a concentration of 1.1 µg/L, which slightly exceeds the 2L standard. A Mobile Multi-Phase Extraction (MMPE) and Groundwater Sampling Report prepared by Schnabel dated April 2007 reported that a MMPE event was performed at on-site wells MW-1, MW-2, MW-6 and WSW-1. Prior to the MMPE event, free product was measured in wells MW-2, MW-6 and WSW-1. The on-site wells were sampled about one month after the completion of the MMPE event. Based on the results of the sampling event, free product was measured in wells MW-2 and MW-6 and various petroleum constituents were detected in wells MW-1, MW-3, MW-4, MW-5 and WSW-1 at concentrations above their respective 2L standards. Schnabel recommended additional MMPE events to remove the free product. Force performed a groundwater sampling event in September 2008 and identified multiple petroleum constituents above their respective 2L standards in wells MW-1, MW-3 and WSW-1. Benzene was detected above its GCL in well MW-1. Reportedly, 0.24 feet of free product was measured in well MW-2, 0.03 feet in well MW-5, and 0.89 feet in well MW-6. Only naphthalene was detected in off- site water supply well WSW-6 at an estimated concentration of 1.6J µg/L. No constituents of concern were detected in the surface water sample from Jonesville Creek. Force also conducted a groundwater sampling event in August 2009 and reported multiple petroleum constituents above their respective 2L standards in wells MW-1, MW-3, MW-4, MW-5, and WSW-1. Benzene was detected above its GCL in well MW-1. Reportedly, well MW-6 contained 0.36 feet of free product. According to the report, well MW-2 could not be located at the site. No constituents of concern were detected in the surface water sample from Jonesville Creek. Force recommended abandonment of well WSW-1 and conducting a MMPE event on wells MW-1, MW-2 and MW-6. Arlington Branco Oil Company Jonesville, North Carolina Terracon Project No. 71149678 Incident No. 30114 February 11, 2016 Responsive ■Resourceful ■Reliable 6 Force completed a second MMPE event at the site in November 2009 at wells MW-1, MW-2, MW-5, and MW-6. Reportedly, 2,800 gallons of petroleum contaminated groundwater were removed from the wells during the MMPE event. Subsequent groundwater sampling in December 2009 indicated free product was measured in wells MW-2 and MW-6 at 0.01 and 0.02 feet, respectively. Dissolved- phase petroleum constituents reportedly decreased significantly in wells MW-1, MW-2, MW-4, MW-5, MW-6 and WSW-1. Force performed groundwater sampling events in July 2011, October 2011 and July 2012 and identified various petroleum constituents in wells MW-1, MW-2, MW-3, MW-4, MW-6 and WSW-1 above their respective 2L standards. Free product was detected in well MW-6 in October 2011 and July 2012. A third MMPE event was conducted by Schnabel in January 2013 at wells MW-1, MW-2, and MW-6. Reportedly, a total of 4,692 gallons of water with dissolved petroleum constituents were removed from the wells during the MMPE event. Subsequent groundwater sampling completed by Force in February 2013 indicated free product [0.4 feet] was detected in well MW-6. Multiple petroleum constituents were detected in wells MW-1, MW-2, MW-3 and MW-5 at concentrations above their respective 2L standards; however, the dissolved-phase constituent concentrations had decreased in these wells. In November 2014, Terracon performed a groundwater monitoring event for the NCDEQ. Terracon sampled six groundwater monitoring wells (MW-1 through MW-6) and surface water from Jonesville Creek. We were unable to sample the on-site water supply well (WSW-1). Petroleum constituents were not detected in Jonesville Creek above 2B surface water standards. Multiple petroleum constituents were detected in wells MW-1, MW-2, MW-3, MW-5, and MW-6 at concentrations that exceeded their respective 2L standards. The findings of the sampling event were issued in a Federal/State-Lead Monitoring Report dated February 2, 2015. Terracon mobilized to the site in May 2015 to sample monitoring wells MW-1 through MW-6, collect a surface water sample from Jonesville Creek and sample on-site water supply well WSW-1. Multiple petroleum constituents were detected in wells MW-1, MW-2, MW-3, MW-5 and MW-6 at concentrations that exceeded their respective 2L groundwater standards. Petroleum constituents were not detected in Jonesville Creek above 2B surface water standards. Benzene and naphthalene were detected in the on-site water supply well WSW-1 at concentrations above their respective 2L standards. Terracon presented the sampling results to the NCDEQ in a Federal/State-Lead Monitoring Report dated June 29, 2015. C.4 Water Supply Wells Reportedly, eleven water supply wells (WSW-1 through WSW-11) are located within 2,000 feet of the site including well WSW-1 which is located on the site. There are no known water supply wells located down-gradient of the site. According to information provided from earlier assessment Arlington Branco Oil Company Jonesville, North Carolina Terracon Project No. 71149678 Incident No. 30114 February 11, 2016 Responsive ■Resourceful ■Reliable 7 activities, ten of the wells including the on-site well are inactive and are located on properties that are reportedly connected to municipal water. Presently, it is unknown if the property containing well WSW-5 is connected to municipal water. Well WSW-5 is located about 1,300 feet southeast of the site within a different local watershed and is not considered to be at risk of impact by the release at the site. A water-supply well inventory prepared by others is presented in Table 1 and the approximate well locations are depicted on Figure 8. C.5 Surface Water According to the USGS topographic map, the site is located within the drainage basin of the Yadkin River which is situated greater than 5,000 feet north of the site. Jonesville Creek, a tributary of the Yadkin River is located along the western property boundary of the site. Surface water features are depicted on Figure 1. C.6 Land Use Information The site is bound to the southwest by Main Street (U.S. Highway 21); to the southeast and east by Dogwood Street; and to the west and northwest by Jonesville Creek. Properties to the north and east are occupied by residences while properties to the south and west are occupied by commercial businesses and residences. D. ASSESSMENT INFORMATION D.1 Site Geology and Hydrogeology The following resources were reviewed to evaluate site-specific geological and hydrogeological characteristics. Elkin South Quadrangle, North Carolina, USGS 7.5-minute series topographic maps, dated 1996 (Figure 1). Geologic Map of North Carolina, dated 1985. The Geology of the Carolinas, Carolina Geological Society Fiftieth Anniversary Volume, edited by J. Wright Horton, Jr., and Victor A. Zullo, The University of Tennessee Press, dated 1991. Soil Survey of Yadkin County, North Carolina, US Department of Agriculture, Natural Resources Conservation Service, Web Soil Survey via the Internet,http://websoilsurvey.nrcs.usda.gov/app/ . The site is located within a thrust-faulted area of the Sauratown Mountains Anticlinorium in the Piedmont Physiographic Province. The Piedmont Province generally consists of low to medium elevation, rounded hills and long rolling northeast to southwest trending ridges with incised creeks and river channels. Underlying rock in the site area is described as fine-grained mica gneiss and metamorphosed granite. Arlington Branco Oil Company Jonesville, North Carolina Terracon Project No. 71149678 Incident No. 30114 February 11, 2016 Responsive ■Resourceful ■Reliable 8 In-place chemical and physical weathering of parent rocks typically form residual soils in the Piedmont region. Weathering is facilitated by the presence of fractures, joints, and less resistant minerals in the rock. In areas not altered by erosion, alluvial deposition or the activities of man, the typical residual soil profile consists of clay-rich unconsolidated materials at the surface, transitioning to sandy silts and silty sands at depth. Typically, the boundary between soil and rock is not sharply defined. This transitional zone is termed “partially weathered rock” or saprolite. Information obtained from the Web Soil Survey for Yadkin County, depicts soils on the site as Fairview sandy clay loam (FdE2). In the Piedmont, groundwater generally occurs in pore spaces within soils and in the structural features present in the underlying rock (i.e. joints, fractures, and faults). Recharge to the water table is primarily by precipitation infiltrating the surficial soils and percolating downward under the influence of gravity to the water table (vadose zone). Typically, the water table is not a level surface, but a subdued reflection of the land surface. The depth to the water table is not consistent and is dependent upon several factors that include the amount of rainfall, permeability of the soil, the extent of fracturing in the underlying rock and the influences of groundwater pumping. Groundwater typically flows in directions parallel to the ground surface and under the influence of gravity, migrates to discharge points such as surface water features, the toes of slopes or natural springs. Fluctuations in the depth of the water table can be expected depending on variations in precipitation, surface water run-off and other factors not evident at the time of our subsurface exploration. Normally, the highest levels of the water table occur in late winter and spring and the lowest levels occur in the late summer and fall. Based on an interpreted groundwater flow direction, groundwater is expected to flow to the southwest from the site. D.2 Sampling Activities D.2.1 Free Product Evaluation Terracon measured a free product thickness of approximately 0.02 feet in monitoring well MW-6 located within the source area. D.2.2 Groundwater Sampling Activities Terracon mobilized to the site on January 8, 2016 to conduct groundwater sampling as requested by the NCDEQ. Prior to sample collection, Terracon gauged the groundwater levels in monitoring wells MW-1, MW-3, MW-4, MW-5 and MW-6. Terracon was unable to open well MW-2. The approximate locations of the wells are shown on the Site Plan (Figure 2). Prior to sampling, the wells were purged a minimum of three well volumes. The wells were allowed to recharge a minimum of 90 percent of the original well volume before samples were collected for analysis. During this sampling event, depth to groundwater in the monitoring wells ranged from approximately 12.16 to 14.64 bgs. The estimated groundwater flow direction is to the southwest towards Jonesville Creek. A groundwater elevation map depicting groundwater elevation contours and flow direction is shown on Figure 3.

Terracon also sampled surface water from Jonesville Creek to evaluate potential impacts to the adjacent drainage feature. Terracon also collected a water sample from water supply well WSW-1 located on the site. Prior to sampling, well WSW-1 was purged using a pump since the water supply well pump had been removed from the well. Terracon purged over 40 gallons from well WSW-1. The groundwater samples and surface water sample were placed in laboratory-supplied glassware, labeled and stored in an ice-packed cooler. The samples, along with chain-of-custody documentation, were delivered to Pace Analytical Services, Inc. in Huntersville, North Carolina for analysis of volatile organic compounds (VOCs) by Standard Method 6200B, including MTBE, EDB and IPE. D.2.3 Analytical Results Laboratory results indicated various petroleum constituents were detected in the monitoring wells at the site. Benzene, 1,2-dichloroethane, IPE, ethylbenzene, isopropylbenzene, MTBE, naphthalene, n- propylbenzene, 1,2,4-trimethylbenzene, 1,3,5-trimethylbenzene, and xylenes were detected at concentrations above their respective 2L groundwater standards in the on-site wells. Recent analytical data compared to historical data seem to display an overall decreasing trend for most of the detected constituents; however, in certain wells, some constituents are static or concentrations have increased. Based on the laboratory results, the extent of the contaminant plume has not been delineated to the east and south. No petroleum constituents were detected above the MDLs in well MW-4 or above the 2B surface water standards in the water sample obtained from Jonesville Creek. The detected groundwater analytical compounds are depicted on Figure 4. Isoconcentration maps for benzene, ethylbenzene and naphthalene are provided as Figures 5, 6, and 7. The groundwater analytical results are summarized in Table 2. A copy of the laboratory analytical report is provided in Appendix A. E. CONCLUSIONS AND RECOMMENDATIONS Based on information obtained during the completion of our assessment activities, Terracon provides the following conclusions and findings. Multiple petroleum constituents were detected in wells MW-1, MW-3 and MW-5 at concentrations that exceed their respective 15A NCAC 2L groundwater standards. Other petroleum constituents were detected in the on-site wells but at concentrations below their respective 2L groundwater standards. None of the detected petroleum constituents exceed GCLs. Groundwater monitoring well MW-6 contained 0.02 feet of free product. The well was not sampled.

Petroleum constituents were not detected in Jonesville Creek above 2B surface water standards. Benzene, naphthalene, n-Propylbenzene and 1,2,4-trimethylbenzene were detected in on-site water supply well WSW-1 at concentrations above their respective 2L standards. Multiple other petroleum constituents were detected in well WSW-1 but at concentrations below their respective 2L groundwater standards. Well WSW-1 is not currently in use as a source of potable water. Based on the data presented in this Pre-Cap Monitoring report, Terracon recommends the following activities be completed at the site. Sample on-site groundwater monitoring wells (MW-1 through MW-6) and Jonesville Creek semi- annually to evaluate the status of impact by petroleum constituents. Terracon recommends the placement of “Bio Socks” into monitoring wells MW-1, MW-2, and MW-3 to reduce the concentrations of dissolved-phase petroleum constituents in the well semi-annually. Terracon recommends the placement of an absorbent well sock into monitoring well MW-6 to remove the free product.
