In accordance with North Carolina Department of Environmental Quality (NC DEQ) regulatory reporting requirements, Apex has prepared a Corrective Action Performance Report for the subject property located at 2825 Lane Street in Kannapolis, North Carolina. This report includes routine system O&M, system repairs, system monitoring, and semi-annual groundwater sampling for the period beginning July 1, 2017 and ending December 31, 2017. The site has been a working supplier of gasoline, diesel, and kerosene since at least 1984 and probably much earlier. From 1966 to 1972 the site was owned by the Humble Oil Company. In 1972 the property owner became Exxon Corporation via a name change. Aerial photographs obtained from Cabarrus County GIS department suggest that the site was a gas station by 1975. It operated as a Starvin Marvin from 1984 and then Speedway America until October 26, 2001, when Pilot Travel Centers, LLC purchased the property. The objective of the Corrective Action Plan (CAP) was to maintain groundwater quality conditions at the site below the applicable 2L Standards for benzene and meth tertbutyl ether (MTBE) while aggressively remediating source area groundwater and minor soil contamination. The corrective action approach to achieve the aforementioned goals for groundwater at the site consisted of an engineered air sparging and soil vapor extraction (SVE) system coupled with monitored natural attenuation. Air sparging will be effective to remove the volatile hydrocarbon constituents, including MTBE from the groundwater. SVE will capture volatile organic vapors from the subsurface and provide an increased pressure gradient to enhance the efficacy of the air sparging. The end of active remediation will be determined when asymptotic conditions are reached in dissolved hydrocarbon concentrations in groundwater or when the applicable 2L standards have been achieved, or risk can be reduced. CAP implementation at the site began in April 2012. Prior to CAP implementation seven monitoring wells (MW-11, MW-12, MW-19, MW-21, MW-23, MW-24, and DMW-3) were above the benzene 2L limit of 1.0 micrograms per liter (µg/L). The MTBE 2L limit of 20 µg/L was exceeded in eight monitoring wells (MW-11, MW-14, MW-17, MW-19, MW-21, MW-23, MW-24, and DMW-3) prior to CAP implementation. At the conclusion of 4t' Quarter 2017 CAP implementation only MW-23 exceeded the benzene 2L CAP endpoint and MW-12, MW-19, MW-23, and DMW-3 exceeded the MTBE 2L CAP endpoint. Petroleum compounds have never been detected in any of the area potable water supplies and sentinel wells such as MW-21, MW-22, and MW-25 continue to indicate that the gasoline plume is confined to the original source zone identified and described in both the CSA and approved CAP. Based on the continued presence of benzene and MTBE above 2L groundwater quality standards in several monitoring wells, Apex recommends continued operation of the remediation system in accordance with the approved CAP.

In accordance with North Carolina Department of Environmental Quality (NC DEQ) regulatory reporting requirements, Apex has prepared a Corrective Action Performance Report for the subject property located at 2825 Lane Street in Kannapolis, North Carolina (Figure 1). This report includes routine system O&M, system repairs, system monitoring, and semi-annual groundwater sampling for the period beginning July 1, 2017 and ending December 31, 2017. The remediation system was installed by Apex in accordance with the NC DEQ-approved Corrective Action Plan (CAP) to address the multiple -phase contaminants identified on the subject property. A description of the remediation system design and function is presented in Section 2.0. A site plan depicting pertinent features of the subject site and surrounding area is provided as Figure 2. This report for system O&M at the Pilot #56 facility is being submitted to Mr. Brett Morris of NC DEQ, on behalf of Pilot. 2.0 SITE HISTORY AND BACKGROUND The site has been a working supplier of gasoline, diesel, and kerosene since at least 1984 and probably much earlier. From 1966 to 1972 the site was owned by the Humble Oil Company. In 1972 the property owner became Exxon Corporation via a name change. Aerial photographs obtained from Cabarrus County GIS department suggest that the site was a gas station by 1975. It operated as a Starvin Marvin from 1984 and then Speedway America until October 26, 2001, when Pilot Travel Centers, LLC purchased the property. According to records reviewed by Apex, seven underground storage tanks (USTs) were closed by removal in May 1994. The UST Closure Report also documented that two 12,000- gallon USTs were removed from service in 1991. The report also documented that there were releases associated with both product lines and the southern UST tank basin. The release was assigned incident number 6379 by the North Carolina Department of Environment and Natural Resources (NCDENR). The site was redeveloped and subjected to active remediation. Following 18 months of active remediation, the incident was closed by NCDENR in 1998. In April 2006, a contractor mobilized to the site to gauge monitoring wells prior to abandonment on behalf of the responsible party for incident 6379. The contractor reportedly discovered light non -aqueous phase liquid (LNAPL) in RW-8 and MW-9. Follow-up investigation in the tank areas and product lines failed to determine a new source. NCDENR considered the LNAPL to be a new release and assigned incident number 36096. Several phases of assessment have occurred since 2006. A site check on the south side of the facility was performed which focused on soils around the new UST basin and the dispenser lines. A total of 22 soil samples were collected for total petroleum hydrocarbons (TPH) gasoline -range organics (GRO) analysis. Nine of the 22 soil samples were analyzed for TPH diesel -range organics (DRO) as well. Four soil samples were reported with GRO concentrations CA Performance Report (July 1 to December 31, 2017) 1 March 19, 2018 Pilot #56 Incident#36096 above the NCDENR UST action level of 10 milligrams per kilogram (mg/kg) at the time of the investigation. DRO was detected in five of the soil samples above 10 mg/kg. A Phase II Limited Site Assessment was conducted and submitted, and the site was assigned a "High Risk" ranking by NCDENR. On February 20, 2009, NCDENR issued a Notice of Regulatory Requirements requesting a Comprehensive Site Assessment (CSA) for the site. A CSA was prepared for the site in December 2009 that delineated the dissolved -phase groundwater contamination vertically and horizontally. An additional round of sampling conducted in September 2010 confirmed the previous delineation. The dissolved -phase hydrocarbon plume did not extend beyond the site property line and the detected groundwater analytes did not exceed the gross contaminant levels (GCLs). The site is ranked `high risk' due to the presence of water supply wells located within a 1,000-foot radius of the source area. It is important to note that all the identified supply wells are located hydraulically cross -gradient of the site and over 425 ft from any exceedances of the North Carolina 15A NCAC 2L groundwater standards (2L). Repeated sampling and analysis of the water supply wells have never detected petroleum hydrocarbons in the samples collected. Furthermore, there are three shallow sentinel wells (MW-22, MW-26, and MW-27) between the source area and the water supply wells that currently and/or historically have met 2L standards. Silty sands dominate the lithology at the site. Shallow soil on site is disturbed and very heavily compacted. Bedrock was encountered at approximately 45 ft below land surface (bls) at DMW-2. Shallow groundwater is encountered at approximately 22 ft bls in the developed portion of the site and flows to the north-northwest. The contaminant of concern is unleaded gasoline. The two primary analytes of concern are meth tertbutyl ether (MTBE) and benzene. Historically there were other exceedances of the 2L standard, but there were no 2L exceedances in wells without having either benzene or MTBE present above 2L standards. The source area was presumed as south of the building, near MW- 24. At the time of CAP development the assumed dissolved groundwater contaminant plume in the south area was approximately 150 ft long by 60 ft wide and 30 ft deep (20 to 50 ft bls). Mass balance calculations indicated that the MTBE mass in the aquifer was approximately thirty gallons and the benzene mass was approximately one gallon. Based on the risk ranking for the site, corrective action objectives (CAOs) listed below were established for each site media by NCDENR. The status of the site in achieving the established CAOs are also noted. According to the North Carolina Administrative Code, (NCAC) 15A 2L .0407 soil must be cleaned up to MSCCs for soil to groundwater or residential standards, whichever is lower. The CAOs for residential soil were achieved prior to CAP implementation. The remediation design in the CAP addressed the nominal soil contamination in the southern area subsurface that remained above soil -to -groundwater standards. According to NCAC 15A 2L .0202, surface water must be remediated to NCAC, 15A 2B standards (213). The 2B standard for benzene was 70 µg/L. The CAOs for surface water at the site were achieved prior to CAP implementation and remedial measures were not carried forward in the CAP. According to NCAC 15A 2L .0202, groundwater at the site must be remediated to the applicable 2L Standards which are 1.0 µg/L and 20 µg/L for benzene and MTBE, respectively. CA Performance Report (July 1 to December 31, 2017) 2 March 19, 2018 Pilot #56 Incident#36096 The objective of the CAP was to maintain groundwater quality conditions at the site below the applicable 2L Standards for benzene and MTBE while aggressively remediating source area groundwater and minor soil contamination. The corrective action approach to achieve the aforementioned goals for groundwater at the site consisted of an engineered air sparging and soil vapor extraction (SVE) system coupled with monitored natural attenuation. Air sparging will be effective to remove the volatile hydrocarbon constituents, including MTBE from the groundwater. SVE will capture volatile organic vapors from the subsurface and provide an increased pressure gradient to enhance the efficacy of the air sparging. The end of active remediation will be determined when asymptotic conditions are reached in dissolved hydrocarbon concentrations in groundwater or when the applicable 2L standards have been achieved, or risk can be reduced. A full description of the remediation system is provided below in Section 3.0. CAP implementation at the site began in April 2012. Prior to CAP implementation seven monitoring wells (MW-11, MW-12, MW-19, MW-21, MW-23, MW-24, and DMW-3) were above the benzene 2L limit of 1.0 µg/L. The MTBE 2L limit of 20 µg/L was exceeded in eight monitoring wells (MW-11, MW-14, MW-17, MW-19, MW-21, MW-23, MW-24, and DMW-3) prior to CAP implementation. At the conclusion of 4ffi Quarter 2017 CAP implementation only MW-23 exceeded the benzene 2L CAP endpoint and MW-12, MW-19, MW-23, and DMW-3 exceeded the MTBE 2L CAP endpoint. 3.0 REMEDIATION SYSTEM The SVE and air sparge remediation system at the Pilot #56 facility was successfully activated on April 18, 2012. The SVE system consists of a Roots Universal RAIV 36 blower (replaced February 2017) paired with a ten horsepower Baldor Electric motor. Together the system module is capable of a maximum extraction rate of 195 actual cubic feet per minute (ACFM) at a vacuum of 12.0 inches of mercury (in Hg). The air sparge system consists of a 15 horsepower "rotary screw" compressor capable of 44-cubic feet per minute (CFM) at 55.0 pounds per square inch (PSI). The complete system is housed in a mobile eight foot by 16 foot enclosed cargo trailer. The SVE manifold contains three "legs" capable of supplying a vacuum at recovery locations SVE-1 through SVE-3. The remediation system layout with SVE well locations is depicted on Figure 3. An air sparge manifold within the remediation system enclosure includes individual gate valves, pressure gauges, pressure regulators, flow meters, and check valves required to properly regulate air flow to allow for optimum treatment of the identified subsurface petroleum constituents at air sparge points AS-1 through AS-16. Activation activities included transportation of the turn -key system to the site and connection to the sub -gradient infrastructure and separately metered power from other site activities. The remediation system layout with air sparge well locations is depicted on Figure 4. 4.0 GROUNDWATER MONITORING During this phase, Apex performed a semi-annual groundwater monitoring event to assess water table elevations and current dissolved -phase contaminant levels. Pursuant to the NC CA Performance Report (July 1 to December 31, 2017) 3 March 19, 2018 Pilot #56 Incident#36096 DEQ-approved CAP, Apex performed monitoring and sampling at monitoring wells MW-9, MW-11, MW-12, MW-14, MW-17, MW-19, MW-20, MW-21, MW-22, MW-23, MW-24, MW- 25, and DMW-3. On December 12, 2017, Apex used a Solinst" electronic interface probe to investigate for the presence of free product and to measure groundwater elevations. Free product was not detected in any of the groundwater monitoring wells gauged during this phase. Groundwater elevation data for the gauging event is presented in Table 1. Groundwater flow direction beneath the site is influenced by water table depression and mounding created by system operation at the recovery/sparge wells; thus, a water table gradient map is not included, but historical groundwater flow direction has been measured to the north-northwest. Monitoring/recovery/air sparge well locations are depicted on Figures 2, 3, and 4. Per NC DEQ-directives, on December 12, 2017, Apex collected groundwater samples from thirteen monitoring wells (MW-9, MW-11, MW-12, MW-14, MW-17, MW-20, MW-19, MW-21, MW-22, MW-23, MW-24, MW-25, and DMW-3). Prior to sampling, Apex purged each well to remove suspended sediment from the water column and to collect samples representative of aquifer conditions. Each well was purged until a minimum of three well volumes had been displaced. Groundwater samples were collected using dedicated, disposable, high -density polyethylene bailers and were transferred directly into the appropriate sample containers immediately upon collection. The samples were stored on ice pending delivery to the laboratory. Disposable, latex gloves were used during all phases of sample collection. Groundwater samples were submitted to ESC Lab Sciences (ESC) in Mount Juliet, Tennessee for volatile organic compound (VOC) analysis via U.S. EPA SW-846 method 6200B. Strict sample security and chain -of -custody documentation were maintained during all phases of transport. Analytical results yielded petroleum compounds in eight of the thirteen monitoring wells sampled, with a maximum MTBE concentration of 1,900 µg/L in monitoring well MW-23. A summary of current groundwater quality data is presented in Table 2. Chain -of -custody documentation and the laboratory Certificates of Analyses are included as Appendix A. Historical groundwater analytical results are provided in Appendix B. The dissolved -phase endpoints for benzene of 1.0 µg/L was only exceeded in MW-23 at 3.61 µg/L. The dissolved - phase endpoint for MTBE of 20 µg/L was exceeded in monitoring wells MW-12, MW-19, MW- 23 and DMW-3, with a maximum exceedance of 1,900 µg/L in MW-23. Isoconcentration maps for benzene and MTBE are provided as Figures 5 and 6, respectively. Per NC DEQ-directives, on December 12, 2017, Apex also collected groundwater samples from five supply wells (5922, 5925, 5927, 5955 Turkey Road and 2865 Lane Street). A sample was not collected from 2847 Lane Street during this phase due to the occupants being away from the property during the sampling event. The supply well samples were collected from outdoor spigots after being purged for approximately ten minutes. Clean, disposable latex gloves were used during all phases of sample collection. The samples were labeled and stored on ice pending delivery to the laboratory. Supply well samples were submitted to ESC for VOC analysis via U.S. EPA SW-846 method 6200B. Strict sample security and chain -of -custody documentation were maintained during all phases of transport. Petroleum constituents were not detected in any of the supply well samples; however, tetrachloroethene at a concentration of 1.20 µg/L was detected in supply well SW-5922. Tetrachloroethene is typically associated with the use of solvents and could be the result of some recent plumbing repairs at the residence. Tetrachloroethene was also detected in SW-5922 during June 2017 sampling at a concentration CA Performance Report (July 1 to December 31, 2017) 4 March 19, 2018 Pilot #56 Incident#36096 of 1.27 µg/L. Historically petroleum compounds have not been detected in any of the supply wells. The laboratory Certificate of Analysis and chain -of -custody records are provided as Appendix A. 5.0 OPERATION AND MAINTANENCE Per NC DEQ directives, Apex performed monthly site visits during this phase for routine O&M activities, system troubleshooting, system repairs, and system monitoring. The various maintenance activities included adding lubricating oil and coolant to the air sparge system air compressor, draining of moisture from the air compressor, greasing of all fittings associated with the SVE blower and motor, replacement of faulty components, and other maintenance activities to maintain system effectiveness. On December 12, 2017 Apex met with Department of Transportation (DOT) staff and their consultant to inspect monitoring wells that were proposed for abandonment during a road construction project at the site. As a result of the construction project Apex turned off AS-5 supplying air to MW-18 pending abandonment by others. Additional wells requiring abandonment for the construction project were MW-3 and MW-19. A tabular summary of the O&M dates and activities performed is presented in Table 3. Copies of the O&M checklists are included as Appendix C. During this phase, the SVE and air sparge system components achieved runtimes of 67% and 29%, respectively. A copy of the well abandonment report is provided as Appendix D. 6.0 CORRECTIVE ACTION PERFORMANCE REPORT SUMMARY Apex has completed CAP implementation activities associated with the Pilot #56 facility located in Kannapolis, North Carolina for the period beginning July 1, 2017 and ending December 31, 2017. At the conclusion of 4th Quarter 2017 CAP implementation only MW-23 exceeded the benzene 2L CAP endpoint and MW-12, MW-19, MW-23, and DMW-3 exceeded the MTBE 2L CAP endpoint. Petroleum compounds have never been detected in any of the area potable water supplies and sentinel wells such as MW-21, MW-22, and MW-25 continue to indicate that the gasoline plume is confined to the original source zone identified and described in both the CSA and approved CAP. Based on the continued presence of benzene and MTBE above 2L groundwater quality standards in several monitoring wells, Apex recommends continued operation of the remediation system in accordance with the approved CAP. System runtime remained consistent during this phase. This report, prepared in accordance with NC DEQ-approved scope of work, is being submitted to Mr. Brett Morris of NC DEQ on behalf of Pilot.

All sample aliquots were received at the correct temperature, in the proper containers, with the appropriate preservatives, and within method specified holding times, unless qualified or notated within the report. All MDL (LOD) and RDL (LOQ) values reported for environmental samples have been corrected for the dilution factor used in the analysis. All radiochemical sample results for solids are reported on a dry weight basis with the exception of tritium, carbon-14 and radon, unless wet weight was requested by the client. All Method and Batch Quality Control are within established criteria except where addressed in this case narrative, a non-conformance form or properly qualified within the sample results. By my digital signature below, I affirm to the best of my knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the quality of the data have been identified by the laboratory, and no information or data have been knowingly withheld that would affect the quality of the data.

NATIONWIDE. The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. Abbreviations and Definitions CP IP FTC MDL Method Detection Limit. ND Not detected at the Reporting Limit (or MDL where applicable). FSS RDL Reported Detection Limit. Rec. Recovery. 4 RPD Relative Percent Difference. Cn SDG Sample Delivery Group. Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and FSr (S) Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media. U Not detected at the Reporting Limit (or MDL where applicable). s QC Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. If the sample matrix contains an interfering material, or if concentrations of analytes in the sample are higher than the Dilution highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal FAI Limits for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. This column provides a letter and/or number designation that corresponds to additional information concerning the result Qualifier reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and SC potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state "ND" (Not Detected) or "BDL" Result (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. A brief discussion about the included sample results, including a discussion of any non -conformances to protocol Case Narrative (Cn) observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control This section of the report includes the results of the laboratory quality control analyses required by procedure or Summary (Qc) analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. This is the document created in the field when your samples were initially collected. This is used to verify the time and Sample Chain of date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This Custody (Sc) chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. This section of your report will provide the results of all testing performed on your samples. These results are provided Sample Results (Sr) by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported. Sample Summary (Ss) This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis. Qualifier Description The remainder of this page intentionally left blank, there are no qualifiers applied to this SDG.

APPENDIX D MW Closure Documentation January 5, 2018 Mr. Gordon Box, L.G. GeoEnviron mental Project Manager Geotechnical Engineering Unit North Carolina Department of Transportation 1589 Mail Service Center Raleigh, NC 27699-1589 Subject: Letter Report of Monitoring Well and Vault Abandonment NCDOT Parcel #75, Pilot Gas Station 2825 Lane Street Kannapolis, Cabarrus County, North Carolina State Project 1-3802A, WBS Element: 36780.1.2 All Foster Wheeler Project: 153053802 Dear Mr. Box: .. arnec foster wheeler Amec Foster Wheeler Environment & Infrastructure, Inc. of North Carolina (Amec Foster Wheeler) is pleased to submit this report to provide documentation of the abandonment of three groundwater monitoring wells, and one remediation vault associated with NCDOT Parcel #75 in the 1-3802A project. This work was conducted in accordance with Amec Foster Wheeler's initial Technical and Cost Proposal dated December 3, 2015 and an Overage Scope Letter dated December 28, 2017. BACKGROUND INFORMATION This parcel is located at 2825 Lane Street in Kannapolis near exit 63 off 1-85. Figure 1 presents the parcel and vicinity map. Amec Foster Wheeler visited the site on December 7, 2017 to confirm the presence of the wells and review the abandonment work with personnel from Blythe Construction and NCDOT Division 10. The monitoring wells MW-18 and MW-19 were located in the south-central portion of the parcel, near the eastern entrance to the gas station off of Lane Street. Wells MW-3 and RW-7, specifically located in a vault, were located in the southwest portion of the parcel near the edge of the parking lot. Figure 2 shows the locations of these wells. According to a city directory search, the site was occupied from 1964 to present. Parcel 75 operates as a gas station and convenience store with a Subway Sandwich Shop, and has been in existence as such since 1994. Its facility ID is #11084. Another service station was present from 1975 to 1994. The property was first used as a residence and farm land in 1964, with no development prior. Thirteen USTs are associated with this facility. Eight were removed May 5, 1994, and five were installed June 30, 1994. A release was observed during the UST removals in 1994 and Amec Foster Wheeler North Carolina Inc. 2801 Yorkmont Road, Suite 100 Charlotte, NC 28208 Tel 704.357.8600 Fax 704.357.8638 www.amec.com Letter Report for Well and Vault Abandonments — NCDOT Parcel #75, 1-3802A 2825 Lane Street, Kannapolis, North Carolina assigned incident #6379. After conducting eighteen months of groundwater remediation, the incident was closed in 1998 by NCDENR, Mooresville Regional Office (MRO). When monitoring wells were to be abandoned in 2006, light non -aqueous phase liquid was identified in two wells by a consultant for the original responsible party and NCDENR assigned new incident #36096 in June of 2006. Since 2006, several phases of assessment have been conducted by multiple consultants. Most recently, a groundwater remediation system utilizing an air sparging curtain with soil vapor extraction commenced in 2010. As far as we've been informed, operation and maintenance occurs twice per month for both the air sparge and soil vapor extraction systems. Groundwater is monitored twice per year through sampling of six monitoring wells. Apex Companies performs the environmental activities for the Pilot Station responsible party. FIELD ACTIVITIES Three groundwater monitoring wells, one remediation well and one vault were abandoned on December 18, 2017, in accordance with North Carolina Administrative Code Title 15A, Subchapter 2C, Section .0100, Rule .0113. To complete the abandonment, Amec Foster Wheeler provided oversight, and contracted Geologic Exploration, a North Carolina licensed driller, to perform the well abandonment activities. Geologic Exploration filled the wells MW-18, MW-19 and MW-3 with grout made from Portland cement to the top of the well casings. Well RW-7, which was part of an historic ground -water extraction remediation system, had all lateral lines cut and the well grouted to its top of casing in the vault. Geologic Exploration then filled the vault that housed the well with grout up to the land surface. Two additional monitoring wells, MW-2 and MW-27, were intended to be abandoned although they hadn't previously been located. A few years ago the service station's grassy islands were minimized and pavement expanded. It is assumed that MW- 2 is under asphalt based on its mapped location. During this effort, MW-27 was thoroughly searched for with metal detector and shovel but to no avail. The well head possible has been covered or removed during landscape, signage or utility improvements in the past years. A Well Abandonment Record for each well has been completed and submitted to the North Carolina Department of Environmental Quality. The Well Abandonment Records are provided in Attachment 1. A photographic log is Attachment 2. A summary of the abandoned monitoring well construction data are presented in the table below.
