B.2 UST Information The subject USTs were constructed of single walled steel that later were lined with fiberglass and are registered with the North Carolina Department of Environmental Quality (NC-DEQ) UST Section. The NC-DEQ UST database reports that the diesel UST was installed during May 1982 while the three 4,000-gallon gasoline USTs were added during May 1984. Product piping associated with the UST systems was single walled steel. See Appendix I, Figure 2 for Site map indicating former UST system locations. Three of the four USTs were closed by removal while the fourth UST (T-8 in Figure 2) had to be closed in-place by filling with concrete because it was located too close to the Stewarts Tire Store, Inc. building to safely remove without undermining the building foundation. Associated product lines were partially removed as well as part of the closure activities. There are no longer any operational petroleum UST systems located on the Site. General information for the USTs removed from the Stewart’s Tire & Auto, Inc. (hereinafter referred to as the “Site”) is based on historical information obtained from the NC-DEQ Registered UST Database, observation made while the UST systems were being removed and from Site representatives. This information is displayed in Table 1 in Appendix II. B.3 Non-UST Information There were no petroleum Aboveground Storage Tanks (ASTs) noted on the Site during the UST removal activities. B.4 Historical Release Description The Site once contained a 2,000-gallon kerosene UST system which released kerosene under the associated product dispenser at some time in the past. The kerosene UST system was removed along with 7.5-tons of petroleum contaminated soil during February 2006. See Figure 2 for former kerosene UST system location. The NC-DEQ assigned the release incident number 29284. Finally, incident 29824 was closed out by the NC-DEQ through issuance of a letter of no further action dated December 6, 2006. Underground Storage Tank Closure Report Stewart’s Tire & Auto, Inc. 2615 Murchison Road, Fayetteville Cumberland County, North Carolina East Coast Environmental, P.A. 3815 Junction Blvd. Raleigh, N.C. 27603 5 B.5 Site Characteristics The Site is currently occupied by the Stewart’s Tire & Auto, Inc. (Figures 1 and 2). The immediately surrounding properties are currently being used primarily for commercial and residential purposes. The Site reportedly did contain four petroleum UST systems prior to the ones that are the subject of this closure report but no new UST systems are planned for installation on the Site. The NC-DEQ database reports that the subject UST systems were installed during 1982 and 1984 and there is no record of a previous petroleum release incident associated with the subject USTs. See Table I for historical summary of all known USTs. The Site has an approximate elevation of 190-feet above mean sea level (MSL) and the Site and surrounding area is gently flat with a very mild slope to the west. Locally, groundwater is expected to flow to the west as well. No subsurface utilities were observed in the excavation while removing the UST systems. The Geologic Map of North Carolina1 locates the Site as being underlain by the Middendorf Formation of the Coastal Plain Physiographic Province. Further, the Geologic Map describes the Middendorf Formation as “Sand, sandstone and mudstone gray to pale gray with an orange cast, mottled; clay balls and iron cemented concretions common, beds laterally discontinuous, cross bedding common”. Observations made by ECE during removal of the USTs revealed that this location is underlain by yellow-orange mottled clayey silt to approximately twelve feet below land surface. Neither groundwater nor rock was observed at the bottom of the excavation. The Site and all surrounding properties utilize potable water supplied by the City of Fayetteville as their water supply. No water supply wells were noted to be located within a 1,000-foot radius of the former UST area. 1 Reference Geologic Map of North Carolina, Department of Natural Resources and Community Development, Division of Land Resources, 1985 edition. Underground Storage Tank Closure Report Stewart’s Tire & Auto, Inc. 2615 Murchison Road, Fayetteville Cumberland County, North Carolina East Coast Environmental, P.A. 3815 Junction Blvd. Raleigh, N.C. 27603 6 C UST CLOSURE C.1 Preparations for UST Closure A UST-3 (Notice of Intent) form was prepared and submitted to the NC-DEQ Fayetteville Regional Office and NC-DEQ Central Office before removal of the subject UST systems. The City of Fayetteville Fire Marshal’s Office was also contacted in order to obtain a permit for the removal of the USTs. See Appendix III for UST-3, UST-2a and City of Fayetteville Fire Marshal UST removal permit fee receipt. C.2 UST Residuals None of the three 4,000-gallon gasoline USTs contained residual liquids. The 3,000-gallon diesel fuel UST contained approximately six inches of water that was removed and disposed of by Creekside Land Development prior to beginning closure activities. C.3 Closure Procedures The UST closure activities were performed by Creekside Land Development during December 14-16, 2022 utilizing an excavator. The subject tanks were noted to be single walled steel which had been upgraded at some time in the past with the installation of internal fiberglass coatings. The associated product lines were constructed of single walled galvanized steel. See Figure 2 for former UST system locations. The excavation made to remove the tanks measured as much as 40-feet in length by 22-feet in width and was up to 12-feet in depth. Observations made by ECE during removal of the USTs revealed that this location is underlain by yellow-orange mottled clayey silt. Neither groundwater nor rock was observed at the bottom of the excavation. Finally, no obvious signs of a petroleum release to the soils under and around the tanks was noted during the UST closure excavation. As sated previously, three of the four USTs were closed by removal while the fourth UST (T-8 in Figure 2) had to be closed in-place by filling with concrete because it was located too close to the Stewarts Tire Store building to safely remove without undermining the building foundation. Associated product lines were partially removed as well as part of the closure activities. There are no longer any operational petroleum UST systems located on the Site. A UST-3 was submitted to the NC-DEQ Central Office and NC-DEQ Fayetteville Regional Office prior to beginning UST closure activities. A UST-2a (Site Investigation Report) has also been submitted to the NC-DEQ Central Office and NC-DEQ Wilmington Regional Office and included as part of this UST Closure Report. See Underground Storage Tank Closure Report Stewart’s Tire & Auto, Inc. 2615 Murchison Road, Fayetteville Cumberland County, North Carolina East Coast Environmental, P.A. 3815 Junction Blvd. Raleigh, N.C. 27603 7 Appendix III for a copy of the UST-3 and UST-2a forms. A UST disposal certificate is also included in Appendix III. C.4 Field Screening Procedures and Observations Field screening of soils consisted of their visual and olfactory profiling after the UST systems were removed from the ground. No petroleum odors or staining were noted in the soils under and surrounding the any of the USTs after their removal. Further, no petroleum odors or staining were noted in soil samples collected from under the former product dispenser locations or from under the product lines collected as part of the UST closure activities. C.5 Soil Sampling At the conclusion of UST removal activities, ECE collected a series of eleven excavation bottom samples from the bottom limits of the UST excavations utilizing a hand auger as shown in Figure 2. Nine additional soil samples were also collected from under the product lines and dispensers for completion of the UST closure activities also utilizing a hand auger. See Figure 3 in Appendix I for soil closure sample locations. Soil samples collected for closure of the UST systems were submitted to ENCO Laboratories of Cary, NC for analysis by EPA method 8015 for Gasoline Range Organics (GRO) and Diesel Range Organics (DRO). Closure samples were collected in order to comply with the North Carolina Department of Environmental Quality (NC- DEQ) “Guidelines for Site Checks, Tank Closure and Initial Response and Abatement for UST Releases March 1, 2007 Version, Change 11 2021” Hereinafter referred to as “The Guidelines”. The results for the soil closure samples collected from under the diesel and gasoline USTs and associated product lines were all below the action levels of 50-mg/kg and 100-mg/kg for GRO and DRO. C.6 Groundwater Sampling No groundwater was encountered while completing the UST excavation therefore no groundwater samples were collected for completion of these UST closure activities. C.7 Quality Control Measures The soil samples collected for laboratory analysis were handled only with clean nitrile gloves and placed in the appropriate laboratory supplied bottles for transportation on ice to ENCO Laboratories or Cary, NC for testing by EPA Method 8015 for GRO and DRO. Underground Storage Tank Closure Report Stewart’s Tire & Auto, Inc. 2615 Murchison Road, Fayetteville Cumberland County, North Carolina East Coast Environmental, P.A. 3815 Junction Blvd. Raleigh, N.C. 27603 8 Specific information related to the samples collected, including date and time of collection, is found on the Chain of Custody forms at the back of the laboratory analytical report in Appendix IV. All nitrile gloves used by ECE personnel during petroleum contaminated soil removal activities were properly discarded, along with any other potentially contaminated articles, immediately after their use. ECE followed standard EPA and NC-DEQ protocols and guidelines for collecting soil samples. It is ECE's belief that the laboratory analytical results provided in this report should not have been adversely affected by our sampling, handling and shipment procedures. Summary of Soil Analytical Results Analytical results for all soil samples collected for completion of these UST closure activities showed either GRO or DRO at concentrations in excess of their action levels of 50 mg/kg and 100-mg/kg, respectively as set forth in the Guidelines. The sample locations for these soil samples can be found in Figure 3. A summary of the analytical data can be found in Table 2 located in Appendix II. C.8 Groundwater Sampling No groundwater samples were collected as part of these closure activities as no groundwater was observed entering the excavation. D CONCLUSIONS ECE has reviewed the information obtained after the removal of three gasoline and one diesel fuel UST systems from the subject locations. Based on ECE's Site observations and the laboratory results for twenty-two soil samples collected for completion of the UST closure activities, it can be concluded that no release of either gasoline or diesel fuel was noted or detected during these closure activities at concentrations in excess of their action levels as set forth in the Guidelines. A copy of this Underground Storage Tank Closure Report should be forwarded to the NC-DEQ Wilmington Regional Office to the attention of Liz Price for review.

The analyte was detected in the associated method blank. The reported value is between the laboratory method detection limit (MDL) and the laboratory method reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable. The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation data and moisture content, where applicable. The concentration indicated for this analyte is an estimated value above the calibration range of the instrument. This value is considered an estimate. Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQL) and is based on the low point of the calibration curve, when applicable, sample preparation factor, dilution factor, and, in the case of soil samples, moisture content. MRL E U J D B N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater confidence) to make a tentative identification". P Greater than 25% concentration difference was observed between the primary and secondary GC column. The lower concentration is reported. PQL: Practical Quantitation Limit. The PQL presented is the laboratory MRL.PQL Calculated analyte - MDL/MRL reported to the highest reporting limit of the component analyses.[CALC] This report relates only to the sample as received by the laboratory, and may only be reproduced in full.FINAL Page 10 of 11Page 10 of 12 Page 11 of 12 Page 12 of 12 102-A Woodwinds Industrial Court Cary NC, 27511 919.467.3090 919.467.3515Phone:FAX:[TOC_1]ENCO Laboratories, Inc.[TOC] ENCO Workorder(s): CF19176 Raleigh, NC 27603 Unless otherwise noted in an attached project narrative, all samples were received in acceptable condition and processed in accordance with the referenced methods/procedures.

The analyte was detected in the associated method blank. The reported value is between the laboratory method detection limit (MDL) and the laboratory method reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable. The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation data and moisture content, where applicable. The concentration indicated for this analyte is an estimated value above the calibration range of the instrument. This value is considered an estimate. Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQL) and is based on the low point of the calibration curve, when applicable, sample preparation factor, dilution factor, and, in the case of soil samples, moisture content. MRL E U J D B N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater confidence) to make a tentative identification". P Greater than 25% concentration difference was observed between the primary and secondary GC column. The lower concentration is reported. PQL: Practical Quantitation Limit. The PQL presented is the laboratory MRL.PQL Calculated analyte - MDL/MRL reported to the highest reporting limit of the component analyses.[CALC] This report relates only to the sample as received by the laboratory, and may only be reproduced in full.FINAL Page 7 of 8Page 7 of 8 Page 8 of 8 ANALYTICAL REPORT PREPARED FOR Attn: Mr. Bill Scott Environmental Conservation Laboratories 102 Woodwinds Industrial Ct, Suite A Cary, North Carolina 27511 Generated 1/4/2023 9:51:17 AM JOB DESCRIPTION CF14992 JOB NUMBER 680-227941-1 See page two for job notes and contact information.
