The license numbers of the company are C-155 (geology) and C-1869 (engineering). i 1st Semi-Annual Corrective Action Plan Monitoring Report – 2014 Executive Summary During the first half of 2014, on behalf of ExxonMobil Environmental Services (EMES), ARCADIS G&M of North Carolina (ARCADIS) completed monthly manual free product monitoring events, and a liquid level monitoring and sampling event at the former ExxonMobil Facility #40962 located at 5001 Raeford Road, Fayetteville, Cumberland County, North Carolina (the site). The objective of the groundwater monitoring and sampling program is to determine concentrations of dissolved-phase chemicals of concern (COCs) and maintain compliance with the North Carolina Department of Environment and Natural Resources (NCDENR) Underground Storage Tank (UST) Program requirements for the site. On March 26, 2014 three (3) groundwater monitoring wells, MW-11D, MW-14, and MW-15, and three (3) soil vapor extraction (SVE) wells, SVE-1/MW-9, SVE-2, and SVE-3, were gauged during the monitoring event to determine depth to bottom (DTB), depth to water (DTW), and depth to product (DTP), if present. Depth to water ranged from 22.48 feet below top of well casing (btoc) in groundwater monitoring well MW-11D to 27.81 feet btoc in SVE well SVE-2. Free product was not detected during the March 26, 2014 gauging event in any wells. Groundwater flow direction was observed to be toward the southeast which is consistent with historical observed groundwater flow direction. Groundwater samples were collected from SVE wells SVE-1/MW-9 and SVE-2 on March 26, 2014. The maximum concentrations of selected dissolved-phase COCs are presented below: Maximum Groundwater Concentrations (March 26, 2014) Chemical of Concern (COC) Monitoring Well ID Concentration (µg/L) GCL Standard (µg/L) Benzene SVE-2 229 5,000 Toluene SVE-2 24,100 260,000 Ethylbenzene SVE-2 3,580 84,500 Xylenes (total) SVE-2 31,400 85,500 Methyl tert-Butyl Ether SVE-2 354 20,000 Diisopropyl ether MW-9/SVE-1 4.24 70,000 Naphthalene SVE-2 1,290 6,000 1,2,4-Trimethylbenzene MW-9/SVE-1 5,830 28,500 1,3,5-Trimethylbenzene SVE-2 1,550 25,000 Tetrachloroethene (PCE) MW-9/SVE-1 1,820 700 Note: Concentrations in Bold exceed the applicable GCL µg/L = micrograms per liter No dissolved-phase concentrations of COCs derived from gasoline constituents were detected in groundwater samples collected at the site on March 26, 2014 in concentrations exceeding the applicable North Carolina Gross Contaminant Level (GCL) standards. ii 1st Semi-Annual Corrective Action Plan Monitoring Report – 2014 Dissolved-phase concentrations of tetrachloroethene (PCE) were detected in groundwater samples collected at SVE well MW-9/SVE-1 exceeding the applicable North Carolina GCL standard. Dissolved-phase concentrations of PCE at the site can be attributed to the chlorinated solvent release at the former dry cleaner property located adjacent to the site across Raeford Road. This property has been assigned NCDENR Dry-Cleaning Solvent Act (DCSA) Identification Number DC260006 and is located upgradient with respect to groundwater flow direction from the site. Monthly free product monitoring visits were conducted on January 8, 2014, February 5, 2014, March 12, 2014, and April 9, 2014. Results of the monthly monitoring and manual recovery events indicated the following: · January 8, 2014: Free product was not detected at either SVE wells SVE-2 or SVE-1/MW-9 during this event. · February 5, 2014: Free product was not detected at either SVE wells SVE-2 or SVE-1/MW-9 during this event. · March 12, 2014: Free product was not detected at either SVE wells SVE-2 or SVE- 1/MW-9 during this event. · April 9, 2014: Free product was not detected at either SVE wells SVE-2 or SVE- 1/MW-9 during this event. ARCADIS recommends the continuation of monthly free product monitoring events at SVE wells SVE-1/MW-9 and SVE-2. The last detection of free product at the site was at SVE- 1/MW-9 on September 23, 2013. The next semi-annual groundwater monitoring and sampling event is scheduled for September 2014. All groundwater monitoring wells and SVE wells associated with the site will be gauged to check for the presence of free product and to determine the potentiometric surface of the site. ARCADIS will collect groundwater samples from SVE wells SVE-1/MW-9 and SVE-2 to be analyzed for volatile organic compounds (VOCs) by Standard Method (SM) 6200B. A groundwater monitoring report detailing the results of the groundwater monitoring and sampling and the monthly free product monitoring events will be submitted to NCDENR for review within 45 days of receipt of the laboratory analytical report. If no free product is detected through September 2014, and gasoline-constituent dissolved- phase COCs are not detected in September 2014 in concentrations exceeding the applicable North Carolina GCL Standards, ARCADIS will respectfully recommend a reclassification of the risk ranking for the site from Intermediate to Low, the completion and filing of a Notice of Residual Petroleum (NORP) with the Cumberland County Register of Deeds, and that No Further Action (NFA) status be granted for the subject incident number. iii 1st Semi-Annual Corrective Action Plan Monitoring Report – 2014 Table of Contents Executive Summary ii 1.0 Site History and Characterization 1 2.0 Free Product 2 3.0 Groundwater Monitoring 3 3.1 Groundwater Gauging 3 3.2 Groundwater Sampling 3 3.3 Groundwater Analytical Results 4 4.0 Site Remediation 5 4.1 Site Remediation to Date 5 5.0 Conclusions and Recommendations 6 Figures 1.

Laboratory Analytical Report and Chain-of-Custody 1 1st Semi-Annual CAP Monitoring Report - 2014 1.0 Site History and Characterization Former ExxonMobil (Exxon) Facility #40962, located at 5001 Raeford Road, Fayetteville, Cumberland County, North Carolina is currently occupied by Li’l Thrift Food Mart, a retail gasoline facility and convenience store. In 1987, a release was discovered from a product line during a tightness test. Three 6,000-gallon gasoline underground storage tanks (USTs), one 570-gallon fuel oil UST, and one 1,000-gallon used oil UST were removed, along with associated piping and dispensers, in February of 1992. Through October 1999, the site underwent active remediation by soil vapor extraction (SVE). The SVE system was connected to monitoring wells MW-9, MW-14 and six vapor extraction wells (VE-1 through VE-6). On October 27, 1999, the SVE system was shut down due to a breach in the subsurface piping. The SVE equipment had been damaged as a result of large quantities of sand moving through the system. ExxonMobil continued hot spot remediation efforts by conducting a series of aggressive fluid vapor recovery (AFVR) events. Additionally, a passive product recovery device was installed in monitoring well SVE-1/MW-9 until 1999. In August 2000, the SVE system was modified and re-connected to monitoring well MW-14 due to high concentrations of dissolved-phase benzene in the monitoring well. Free product was detected in monitoring wells SVE-1/MW-9 and MW-14. Subsequently, SVE-1/MW-9 was re-connected to the SVE system in August 2002. The SVE system operated at monitoring wells SVE-1/MW-9 and MW-14 from August 2002 until May 2005, when the system was shut down due to damaged SVE piping once again. A mobile multi-phase extraction (MMPE) event was conducted in May 2009. Two (2) additional SVE wells (SVE- 2 and SVE-3) were also installed in 2009. The site is located in a commercially developed area of Fayetteville within the city limits. Topography at the site is generally flat with an average grade of approximately 1.0% to the northwest. Soils at the site generally consist of sandstone and sandy mudstone, with clays present. The water table occurs at depths of 11 to 31 feet below ground surface (bgs) and groundwater generally flows to the southeast in the vicinity of the site. The nearest surface water body to the site is Beaver Creek, located approximately 4,200 feet to the southwest. On October 23, 2011, an updated potable well survey was submitted to NCDENR. The updated potable well survey indicated that two potable wells were located upgradient of the site. Based on an evaluation of the historic potentiometric/groundwater flow direction and the lack of off-site impacts, ARCADIS determined that impacts to the upgradient potable wells would not occur. After reviewing the results of the updated potable well survey, NCDENR lowered the site risk classification from High to Intermediate. As an intermediate risk site, groundwater analytical cleanup standards will be held to the North Carolina Gross 2 1st Semi-Annual CAP Monitoring Report - 2014 Contaminant Levels (GCLs). A Site Location Map is presented in Figure 1 and a Site Map is shown as Figure 2. 2.0 Free Product From June 1996 to present, free product has been historically observed in groundwater monitoring wells MW-1 and MW-14 and SVE wells SVE-1/MW-9, SVE-2 and SVE-3 at maximum thicknesses of 0.01 feet, 2.00 feet, 2.63 feet, 3.12 feet, and 0.07 feet, respectively. Monthly free product monitoring was conducted at the site during the first half of the 2014 monitoring period. SVE wells SVE-1/MW-9 and SVE-2 were gauged monthly to determine depth to bottom (DTB), depth to water (DTW) and depth to product (DTP), if present. · January 8, 2014: Free product was not detected at either SVE wells SVE-2 or SVE-1/MW-9 during this event. · February 5, 2014: Free product was not detected at either SVE wells SVE-2 or SVE-1/MW-9 during this event. · March 11, 2014: Free product was not detected at either SVE wells SVE-2 or SVE-1/MW-9 during this event. · April 9, 2014: Free product was not detected at either SVE wells SVE-2 or SVE-1/MW-9 during this event. Free product has historically been recovered by manual bailing methods using a polyethylene bailer and nylon rope, and by placing petroleum absorbent socks in the SVE wells to facilitate passive free product recovery at the completion of the manual bailing activities. Recovered free product was stored in a dedicated 55-gallon department of transportation (DOT) approved steel drum and was characterized as non-hazardous. Free product was last detected at the site at SVE well MW-9/SVE-1 on September 23, 2014 at a maximum apparent thickness of 0.12 feet. Current and historical groundwater elevations along with free product thickness data are summarized in Table 1. 3 1st Semi-Annual CAP Monitoring Report - 2014 3.0 Groundwater Monitoring 3.1 Groundwater Gauging On March 26, 2014, ARCADIS G&M of North Carolina, Inc. (ARCADIS) personnel gauged three (3) groundwater monitoring wells MW-11D, MW-14, and MW-15, and three (3) SVE wells, SVE-1/MW-9, SVE-2 and SVE-3. Groundwater monitoring wells MW-12, MW-13, MW-16, and MW-20 were could not be located during the March 26, 2014 gauging event. Groundwater gauging was conducted with an oil/water interface probe (IP) prior to purging and sampling to determine DTB, DTW and DTP, if present. The IP and attached tape, marked in 0.01-foot increments, was properly decontaminated before each use with Alconox soap and rinsed with distilled water. The DTW was measured from the marked survey point on the top of the well casing (TOC). All measurements were recorded to the nearest 0.01-foot increment. Current and historical groundwater elevations are summarized in Table 1. Depths to water from the March 26, 2014 groundwater gauging event ranged from 22.48 feet below top of well casing (btoc) in groundwater monitoring well MW-11D to 27.81 feet btoc in soil vapor extraction well SVE-1. Free product was not detected during the March 26, 2014 groundwater gauging event. A potentiometric surface map showing groundwater elevations for all groundwater monitoring wells gauged is presented as Figure 3. Groundwater flow direction was observed to be toward the southeast which is consistent with historical observed groundwater flow direction. 3.2 Groundwater Sampling On March 26, 2014, soil vapor extraction wells SVE-1/MW-9 and SVE-2 were purged of stagnant water. Prior to purging, the amount of water to be removed was calculated using the following formula: 3.1415 x r2 x (TD – DTW) x 7.481 = gallons of water (1 well volume) Where: r = radius of well (in feet) TD = total depth of well (in feet) DTW = depth to water (in feet) In order to ensure that the water in the SVE well after purging was representative of the water in the aquifer, a minimum of three well volumes was removed. Groundwater monitoring wells that did not generate three well volumes of water were bailed dry and then 4 1st Semi-Annual CAP Monitoring Report - 2014 given sufficient time to allow for recharging. All sampling tasks were completed within 24 hours of purging. Groundwater samples were obtained from soil vapor extraction wells SVE-1/MW-9 and SVE-2 using a disposable polyethylene bailer and new nylon rope. All groundwater samples were placed in laboratory-supplied containers and shipped on wet ice to TestAmerica, Inc. in Nashville, Tennessee, for analysis of volatile organic compounds (VOCs) by Standard Method (SM) 6200B. Groundwater samples submitted for VOC analysis were placed in triplicate 40-milliliter (mL) volatile organic analysis (VOA) glass vials with Teflon-lined septa screw caps preserved with hydrochloric acid (HCl). Laboratory analytical results and chain-of-custody documentation are included as Appendix A. 3.3 Groundwater Analytical Results Analytical data from the March 26, 2014 groundwater sampling event indicated the following: · Dissolved-phase concentrations of tetrachloroethene (PCE) were detected in concentrations exceeding the applicable North Carolina Gross Contaminant Level (GCL) Standard (700 microgram per liter (µg/L)) at SVE well MW-9/SVE-1 at 1,820 µg/L. Dissolved-phase concentrations of PCE at the site can be attributed to the chlorinated solvent release at the former dry cleaner property located adjacent to the site across Raeford Road. This property has been assigned NCDENR Dry-Cleaning Solvent Act (DCSA) Identification Number DC260006 and is located upgradient with respect to groundwater flow direction from the site. Current and historical groundwater analytical data is presented in Table 2. A groundwater analytical map is presented as Figure 4. An isoconcentration map depicting the dissolved- phase extent of PCE at the site in included as Figure 5. The Laboratory analytical results and chain-of-custody documentation are included as Appendix A The maximum dissolved phase concentrations for select COCs detected on March 26, 2014 are listed in the table below: 5 1st Semi-Annual CAP Monitoring Report - 2014 Maximum Groundwater Concentrations (March 26, 2014) Chemical of Concern (COC) Monitoring Well ID Concentration (µg/L) GCL Standard (µg/L) Benzene SVE-2 229 5,000 Toluene SVE-2 24,100 260,000 Ethylbenzene SVE-2 3,580 84,500 Xylenes (total) SVE-2 31,400 85,500 Methyl tert-Butyl Ether (MTBE) SVE-2 354 20,000 Diisopropyl ether (IPE) MW-9/SVE-1 4.24 70,000 Naphthalene SVE-2 1,290 6,000 1,2,4-Trimethylbenzene MW-9/SVE-1 5,830 28,500 1,3,5-Trimethylbenzene SVE-2 1,550 25,000 Tetrachloroethene (PCE) MW-9/SVE-1 1,820 700 Note: Concentrations in Bold exceed the applicable GCL µg/L = micrograms per liter 4.0 Site Remediation 4.1 Remediation Activities to Date Summarized in the table below is a chronology of remediation activities performed at the site to date: 6 1st Semi-Annual CAP Monitoring Report - 2014 Remediation Activities to Date Date Activity 1987 to 1998 Manual and passive recovery and SVE System operated – 893.5 pounds (lbs.) of TPH recovered.
