ABSTRACT
Cohesion, Inc. was contracted to remove a heating oil underground storage tank. The property is located in a commercial area in downtown Sanford, NC. Lee County records indicate the building was constructed in 1955. The building was constructed for use as funeral services. The building is currently under renovation to be used for office space.
On February 8, 2023, Cohesion initiated field activities by removing the concrete floor covering the underground storage tank (UST). On February 9, 2023, a fluid removal contractor pumped and cleaned the tank. On February 16, 2023, Cohesion personnel excavated the overburden and removed the UST. Soil retrieved from beneath the UST exhibited a petroleum odor. Laboratory analysis of retrieved soil detected heating oil type
petroleum hydrocarbons exceeding the NCDENR action level of 100 mg/kg, indicating there had been a release from the UST. A soil boring conducted in the pit indicated soil contamination above action levels at a depth of 13.5 feet below ground surface. The former UST was located beneath the concrete floor of the site building. The property owner will likely seek to record a notice of residual petroleum (NRP) due to the location
of the contamination. This report was prepared and reviewed under the supervision of John Sherrill, LG of Sherrill Environmental. Sampling and testing procedures were conducted in accordance with the standards of care associated with the equipment and testing methods. Field and
lab procedures are regularly monitored for quality assurance. The analytical results contained in this report were generated using a QED Hydrocarbon Analyzer from QROS, Ltd. The QED UVF method is the only NCDEQ approved method for replacement of Gas Chromatography (Method 8015). The system is limited to 1 mg/kg
detection limits in soil and 0.05 mg/l in water for most petroleum fuels and oils, which is well within the limits required to perform the analysis herein.

INITIAL RESPONSE AND ABATEMENT ACTIVITIES
Quantity of Regulated Substance Removed from USTs
On February 9, 2023, Red Star Oil Company removed 204 gallons of residual fluid. The
fluid disposal receipt is attached in Appendix A.

5
Source Control Actions The tank was removed on February 16, 2023. The tank disposal manifest is attached in Appendix B. Contaminant Migration Control Measures
The tank was removed in accordance with industry accepted standards. Measures taken to Mitigate Fire/Safety Hazards The tank was removed in accordance with industry accepted standards. Contaminated Soil Storage, Treatment and/or Disposal
No impacted soil was removed. Status of Free Product Investigation and Associated Removal No free product was encountered in the soil. SOURCE INVESTIGATION
On February 8, 2023, field activities were initiated by removing the concrete floor covering the underground storage tank (UST). On February 9, 2023, Cohesion met with the fluid removal contractor at the tank site. Residual fluid was removed from the tank. The interior
of the tank was cleaned, and rinse-water was removed. A total of 204 gallons of fluid were
removed and transported for offsite disposal. The fluid disposal manifest is attached in Appendix A. On February 16, 2023 the tank was removed, loaded and transported off site for proper disposal. The tank disposal manifest is attached in Appendix B.
After the tank was removed, soil samples B-1 and B-2 were collected on opposite ends
from the bottom of the pit (approximately six feet below land surface). A strong petroleum odor was observed in the soil samples. The samples were analyzed for total petroleum hydrocarbons (TPH) using a QED analyzer. Analysis of sample B-1 detected a TPH diesel range organics (DRO) concentration of 35,624 mg/kg and TPH gasoline range organics
(GRO) concentration of 3,990 mg/kg. Sample B-2 analysis detected a TPH-DRO
concentration of 33,633 mg/kg and TPH-GRO concentration of 2,861 mg/kg. The detected TPH concentrations of both samples exceeds the North Carolina Department of Environmental Quality’s (NCDEQ’s) TPH cleanup limits for TPH-DRO of 100 mg/kg and TPH-GRO of 50 mg/kg.
In an attempt to determine the depth of the release, four soil samples (S1-A, S1-B, S1-C and S1-D) were collected from a single boring starting at the bottom of the pit. S1-A was collected from a depth of eight (8) feet below land surface (bls), S1-B from ten (10) feet bls, S1-C from 12 feet bls and S1-D at 13.5 feet bls. Another soil sample (SW-1) was
collected from the sidewall to determine the lateral extent in that direction. Sample locations are indicated in Figure 4. TPH analysis detected concentrations in all the boring samples exceeding NCDEQ’s TPH cleanup limits for TPH-DRO of 100 mg/kg and TPH-GRO of 50 mg/kg. The analytical
6
results are summarized on Table 1, and the analytical reports are included in Appendix C.
No impacted soil was removed for off-site disposal. While a receptor survey was not
conducted, it is believed no water supply wells are present within 150 feet of the source area. A Notice of Residual Petroleum (NRP) will be required by NCDEQ; unless all petroleum impacted soil exceeding NCDEQ applicable standards is removed.
