Upon removal of the two USTs, V GIS Address matching two leak detection soil samples were collected from the base of each of the two UST pits for laboratory analysis of TPH-DRO and TPH-GRO see Table B-3 attached). All 4 release detection samples exceeded NCDEQ's TPH-DRO ✓ Other — Google Earth ❑ Unknown screening level of 100 ppm, with levels ranging from 2,040 to 10,500 ppm. One release detection sample exceeded NCDEQ's TPH-GRO screening level of 50 ppm, with a level of 75 ppm. An attempt was made to excavate all Describe location: petroleum -impacted soil, confirmatory soil samples were collected for laboratory analysis, and an Initial Abatement Action Report is under preparation. The confirmatory soil sample analytical results at the base and two sidewalls of the excavation show exceedances of residential MSCCs; therefore, a Limited Site Assessment is being planned.

Box 7030, Charlotte, NC 28241 March 9, 2021 UST Form 61 (05/17) Page 2 of 2 Definitions of Sources: Tank: means the tank that stores the product and is part of the underground storage tank system Piping: means the piping and connectors running from the tank or submersible turbine pump to the dispenser or other end -use equipment (Vent, vapor recovery, or fill lines are excluded.) Dispenser: includes the dispenser and the equipment used to connect the dispenser to the piping (e.g., a release from a suction pump or from components located above the shear valve) Submersible Turbine Pump (STP): Area includes the submersible turbine pump head (typically located in the tank sump), the line leak detector, and the piping that connects the submersible turbine pump to the tank Delivery Problem: identifies releases that occurred during product delivery to the tank. (Typical causes associated with this source are spills and overfills.) Other: serves as the option to use when the release source is known but does not fit into one of the preceding categories (e.g., for releases from vent lines, vapor recovery lines, and fill lines) Unknown: identifies releases for which the source has not been determined Definitions of Causes: Spill: use this cause when a spill occurs (e.g., when the delivery hose is disconnected from the tank fill pipe or when the nozzle is removed from the dispenser) Overfill: use when an overfill occurs (e.g., overfills may occur from the fill pipe at the tank or when the nozzle fails to shut off at the dispenser) Corrosion: use when a metal tank, piping, or other component has a release due to corrosion (e.g., for steel, corrosion takes the form of rust) Physical or Mechanical Damage: use for all types of physical or mechanical damage, except corrosion (e.g., puncture of tank or piping, loose fittings, broken components, and components that have changed dimension) Installation Problem: use when the problem is determined to have occurred specifically because the UST system was not installed properly Other: use this option when the cause is known but does not fit into one of the preceding categories (e.g., putting regulated substances into monitoring wells) Unknown: use when the cause has not been determined A} 1 - I Ir rhl ` 2 NY iy fADOW LN I PALES,TR/NA, q W \\ V KINGBIRD CT O Y - - ------ T7, Ali C^ C" ROC.Y \ 6 CAURf[ WIG C f[ Y Ct OP CELLO ` Z CT - CHANTRESS LN -� CALLISON CT 2� , �, AVENING CT h 1 _ f VER ICA pR HARPLEY CT t� / _ = SERENADE CT w � . t P1 Q lr tf's, I S�1 v 4` .� I rTEwARrs- OSSING Girt e�Qo� j GLENMACRD �� v S - j"'`�•sr el v i \ 4 //.

ND - Not Detected at or above adjusted reporting limit. TNTC - Too Numerous To Count J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit. MDL -Adjusted Method Detection Limit. PQL - Practical Quantitation Limit. RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and bias for a specific analyte in a specific matrix. S - Surrogate 1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is a combined concentration. Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values. LCS(D) - Laboratory Control Sample (Duplicate) MS(D) - Matrix Spike (Duplicate) DUP - Sample Duplicate RPD - Relative Percent Difference NC - Not Calculable. SG - Silica Gel - Clean -Up U - Indicates the compound was analyzed for, but not detected. Acid preservation may not be appropriate for 2 Chloroethylvinyl ether. A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA Method 8260. N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for each analyte is a combined concentration. Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes. TNI -The NELAC Institute. ANALYTE QUALIFIERS Analyte was detected in the associated method blank. D3 Sample was diluted due to the presence of high levels of non -target analytes or other matrix interference. E Analyte concentration exceeded the calibration range. The reported result is estimated. IL This analyte exceeded secondary source verification criteria low for the initial calibration. The reported results should be considered an estimated value. J Analyte detected below the reporting limit, therefore result is an estimate. This qualifier is also used for all TICs. M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery. N2 The lab does not hold NELAC/TNI accreditation for this parameter but other accreditations/certifications may apply. A complete list of accreditations/certifications is available upon request. R1 RPD value was outside control limits. S2 Surrogate recovery outside laboratory control limits due to matrix interferences (confirmed by similar results from sample re -analysis). S4 Surrogate recovery not evaluated against control limits due to sample dilution. S5 Surrogate recovery outside control limits due to matrix interferences (not confirmed by re -analysis). ST Surrogate recovery was above laboratory control limits. Results may be biased high. v1 The continuing calibration verification was above the method acceptance limit.
