EXECUTIVE SUMMARY
The Texaco Food Mart site is a former petroleum retail facility and former convenience store located at 1700
Cotton Grove Road, in Lexington, Davidson County, North Carolina. The store building and canopy were razed
before the October 2018 UST closure and the lot is now vacant. Two 8,000-gallon gasoline, two 4,000-gallon
gasoline, one 4,000-gallon diesel, and one 1,000-gallon kerosene USTs, associated dispensers and product piping
were removed from the site between October 15 and 16, 2018. A previous UST system was removed from the
site on May 31, 1989 which consisted of one 2,000-gallon gasoline and one 1,000-gallon diesel USTs. A
previous incident occurred on February 8, 1999 and was reported to NCDEQ on June 2, 1999 and was assigned
an Incident Number 22332. Several monitoring wells are located around the former UST Basins and ongoing
ground water assessment continues at the site including MMPE events. Based on past monitoring reports, several
water supply wells are located within a 1,000-foot radius of the site. The site is located inside the town limits of
Lexington and is zoned Business (B). Municipal water is reportedly available to the site and surrounding areas.
The gasoline and diesel USTs were located in UST Basin #1 and were buried at a depth of approximately 3 feet
bgs. The kerosene UST was located in UST Basin #2 and was buried at a depth of approximately 2 feet bgs. The
excavation of the UST Basins #1 and #2 were limited in size to only allow for the removal of the USTs from the
basins. A total of 117.25 tons of overburden soils were excavated from UST Basin #1 and transported offsite for
disposal. No petroleum odors were observed in the soil beneath the USTs from UST Basin #1. Closure soil
samples were collected beneath the USTs, dispensers and product piping and submitted for on-site analysis by the
mobile laboratory for TPH-GRO and TPH-DRO using UVF technology. Product line samples for the diesel UST
were not collected because the dispenser was located above the UST basin. Concentrations in soil samples
collected at UST Basin #1 were all below the RALs. Concentration of TPH-GRO in UST closure sample DI-3
(3’) collected beneath the gasoline dispenser located on the west side of the property exceeded the RAL.
Concentrations of TPH-GRO and/or TPH-DRO that exceed the RALs were reported in the soil samples UST-6-1
(7’) and DI-1 (3’), collected from beneath the kerosene UST and dispenser at UST Basin #2. Based on these
results, 22.44 tons of petroleum impacted soils were removed from the base of UST Basin #2 and dispenser area
and transported off site for disposal. Following over-excavation activities at UST Basin #2 and dispenser area,
confirmation soil sample UST-6-3 (8’) was collected at the base of UST Basin #2 excavation at a depth of 8 feet
bgs and submitted for on-site analysis by RedLab for TPH-GRO and TPH-DRO using UVF technology. No
detectable concentrations of TPH-GRO and/or TPH-DRO were reported in the soil sample collected from UST-6-
3 (8’). Neither ground water nor bedrock were encountered during excavation activities. In addition, no free
product was encountered excavation activities.
Based on this information, GRI recommends no further UST closure assessment at this facility.

1.0 INTRODUCTION
The purpose of this report is to present the results of the underground storage tank (UST) closure
activities that were conducted between October 15 and October 16, 2018, at the Texaco Food Mart site
located at 1700 Cotton Grove Road in Lexington, Davidson County, North Carolina (Figure 1). The
Texaco Food Mart site is a former petroleum retail facility and former convenience store. The store
building and canopy were razed before the October 2018 UST closure and the lot is now vacant. The site
is located inside the town limits of Lexington and is zoned Business (B). Municipal water is reportedly
available to the site and surrounding area. Two 8,000-gallon gasoline, two 4,000-gallon gasoline, one
4,000-gallon diesel, and one 1,000-gallon kerosene USTs, associated dispensers and product piping were
removed from the site between October 15 and 16, 2018.
A previous UST system was removed from the site on May 31, 1989 which consisted of one 2,000-
gallon gasoline and one 1,000-gallon diesel USTs. A previous incident occurred on February 8, 1999
and was reported to the North Carolina Department of Environmental Quality (NCDEQ) on June 2, 1999
and was assigned an Incident Number 22332. Several monitoring wells are located around the former
UST Basins and ongoing ground water assessment continues at the site including Mobile Multi-Phase
Extraction (MMPE) events. Several water supply wells are located within a 1,000-foot radius of the site
based on past monitoring reports.
2.0 INITIAL ABATEMENT ACTIVITIES
Prior to closure activities, the appropriate officials were notified (i.e. Fire Marshal and
NCDEQ). According to the City of Lexington’s Fire Marshal, a fire permit was required for the
removal of the UST system. In addition, the City of Lexington’s permitting office required a
demolition permit for the removal of the store building and canopy. Copies of the Fire Permit
and Demolition Permit have been included as Appendix A. A Notice of Intent: UST Permanent
Closure or Change-in-Service (UST-3) Form was submitted to NCDEQ on July 27, 2018. A
copy of the UST-3 Form has been included as Appendix B. A copy of the Site Investigation
Report for Permanent Closure or Change-in-Service of UST (UST-2A) Form has been included
as Appendix C. A Site Specific Health and Safety Plan is included as Appendix D.
UST Owner and System Information: The UST owner and operator information has been
summarized in the attached Table 1. UST System information has been summarized in Table
2. A Site Map showing the location of the USTs has been provided as Figure 2.
Quantity of Regulated Substance Removed from UST: Prior to the initiation of the UST
2
closure activities, 86 gallons of residual liquid were removed from the USTs by Hazmat
Emergency Response and Remediation (HERR). A liquid disposal manifest is included as
Appendix E.
Source Control Actions: Two 8,000-gallon gasoline, two 4,000-gallon gasoline, one 4,000-
gallon diesel, and one 1,000-gallon kerosene USTs, associated dispensers and product piping
were removed from the site between October 15 and 16, 2018.
Contaminant Migration Control Measures: A total of 139.69 tons of soils were excavated
from the site during UST closure activities; 117.25 tons of overburden soils were excavated
from UST Basin #1 and 22.44 tons of overburden and over-excavated soils were removed from
the UST Basin #2 and kerosene dispenser area during UST closure activities.
Measures Taken to Mitigate Fire/Safety Hazards: The City of Lexington’s Fire Marshal
approved GRI’s tank inertion methods and removal procedures. Prior to closure, the
atmosphere of each UST was checked with an LEL/02 meter; once the UST atmosphere reached
less than 10% LEL, the tank was removed. No free product or water was noted in the
excavation. There did not appear to be any immediate fire or safety hazards present as a result
of the release.
Contaminated Soil Storage/Treatment and/or Disposal: A total of 139.69 tons of soils were
excavated from the site during UST closure activities and were loaded directly into dump trucks
and transported to a permitted disposal facility. A total of 117.25 tons of overburden soils were
excavated from the UST Basin #1 and 22.44 tons of overburden and over-excavated soils were
removed from the UST basin #2 and kerosene dispenser area during UST closure activities.
Copies of the soil disposal manifests for soils removed during the October 2018 UST closure
activities have been included as Appendix F.
3.0 SOURCE INVESTIGATION
On October 9, 2018, the Texaco Food Mart store building and canopy were razed during demolition
activities prior to conducting UST closure activities. On October 15, 2018, GRI staff and equipment
were mobilized to the site to conduct UST closure activities of the two 8,000-gallon gasoline, two 4,000-
gallon gasoline, one 4,000-gallon diesel, and one 1,000-gallon kerosene USTs, associated dispensers and
product piping. The gasoline and diesel USTs were located in UST Basin #1 and were buried at a depth
of approximately 3 feet below ground surface (bgs). The kerosene UST was located in UST Basin #2
and was buried at a depth of approximately 2 feet bgs. The 8,000-gallon gasoline USTs were 8 feet in
diameter and 21.3 feet in length and the 4,000-gallon diesel UST was 5.3 feet in diameter and 24 feet in
3
length. The USTs were visually inspected upon extraction and appeared to be in good condition with no
visible corrosion and/or pitting. The three USTs were constructed of fiberglass clad steel. The two
4,000-gallon gasoline USTs were 5.3 feet in diameter and 24 feet in length and the 1,000-gallon
kerosene UST was 4 feet in diameter and 10.5 feet in length. Both the 4,000-gallon gasoline USTs
appeared to be in good condition with no visible corrosion and/or pitting. The 1,000-gallon kerosene
UST appeared to be in poor condition with visible corrosion and pitting. The three USTs were
constructed of steel. The USTs were transported off site for proper disposal. Disposal manifests for the
USTs are included as Appendix G.
The excavations of the gasoline and diesel tanks in UST Basin #1 and the kerosene tank in UST Basin
#2 were limited in size to only allow for the removal of the USTs from the basin. A total of 117.25 tons
of overburden soils were excavated from UST Basin #1 and transported offsite for disposal. No
petroleum odors were noted in the soils beneath the USTs at UST Basin #1. At UST Basin #2, 22.44
tons of overburden soils and soils from immediately below the 1,000-gallon kerosene UST and kerosene
dispenser were excavated and transported offsite for disposal based on field screening results. Neither
ground water nor bedrock were encountered during excavation activities. In addition, no free product
was encountered during the excavation activities. At UST Basin #1, closure soil samples UST-1-1 (9’),
UST-1-2 (9’), UST-1-3 (9’), UST-2-1 (9’), UST-2-2 (9’), UST-2-3 (9’), UST-5-1 (9’), UST-5-2 (9’)
and UST-5-3 (9’) were collected beneath the two 4,000-gallon gasoline USTs and the 4,000-gallon
diesel UST at a depth of 9 feet bgs. Closure soil samples UST-3-1 (12’), UST-3-2 (12’), UST-3-3
(12’), UST-4-1 (12’), UST-4-2 (12’) and UST-4-3 (12’) were collected beneath the two 8,000-gallon
gasoline USTs at a depth of 12 feet bgs. At UST Basin #2, closure soil samples UST-6-1 (7’) and UST-
6-2 (7’) were collected beneath the 1,000-gallon kerosene UST at a depth of 7 feet bgs. All soil samples
were submitted for on-site analysis by Rapid Environmental Diagnostics (RedLab) for gasoline-range
and diesel-range Total Petroleum Hydrocarbons (TPH-GRO and TPH-DRO) using North Carolina
accepted UVF technology.
Two gasoline dispensers were located on separate dispenser islands (Island #1 and Island #2), one
kerosene and one diesel dispensers are also located at the site on separate islands and were removed
during UST closure activities. Soil samples DI-1 (3’) through DI-4 (3’) were collected beneath the
dispensers at a depth of approximately 3 feet bgs. During excavation activities the fiberglass product
lines were removed. Three soil samples (PP-1 (3’), PP-2 (3’) and PP-3 (3’)) were collected beneath the
gasoline product lines at a depth of 3 feet bgs and was submitted for on-site analysis by RedLab for
4
TPH-GRO and TPH-DRO using UVF technology. Product line samples were not collected at the
kerosene and diesel dispensers because the dispensers were located adjacent and/or above the associated
USTs.
Detectable concentrations of TPH-GRO and/or TPH-DRO that did not exceed the Regulatory Action
Levels (RALs) were reported in the soil samples UST-1-1 (9’), UST-1-2 (9’), UST-1-3 (9’), UST-2-1
(9’), UST-2-2 (9’), UST-2-3 (9’), UST-3-1 (12’), UST-3-2 (12’), UST-3-3 (12’), UST-4-1 (12’), UST-
4-2 (12’), UST-5-3 (9’), UST-6-2 (7’), DI-4 (3’) and PP-2 (3’). Concentrations of TPH-GRO and/or
TPH-DRO that exceed the RALs were reported in the soil samples collected from UST-6-1 (7’), DI-1
(3’) and DI-3 (3’). Based on field screening results, 22.44 tons of overburden soils and soils from below
the kerosene UST and kerosene dispenser were excavated and transported offsite for disposal. Following
over-excavation activities at the kerosene UST in Basin #2, a confirmation soil sample (UST-6-3 (8’))
was collected at the base of the excavation at a depth of 8 feet bgs and submitted for analysis by RedLab
for TPH-GRO and TPH-DRO using UVF technology. No detectable concentrations of TPH-GRO
and/or TPH-DRO were reported in the soil sample collected from UST-6-3 (8’).
All soil samples were collected using either a hand auger or directly from the bucket of the excavator.
Soil sample locations are shown on Figure 3. Soil quality results are shown on Figure 4. Soil sample
analytical results are presented in Table 3. A copy of the laboratory report is presented as Appendix H.
4.0 SUMMARY AND CONCLUSIONS
The Texaco Food Mart site is a former petroleum retail facility and former convenience store.
The store building and canopy were razed before the October UST closure and the lot is now
vacant.
The site is located inside the town limits of Lexington and is zoned Business (B). Municipal
water is reportedly available to the site and surrounding properties.
A previous incident occurred on February 8, 1999 and was reported to the NCDEQ on June 2,
1999 and was assigned an Incident Number 22332. Several monitoring wells are located around
the former UST basins and ongoing ground water assessment continues at the site including
MMPE events. Several water supply wells are located within a 1,000-foot radius of the site
based on past monitoring reports.
Two 8,000-gallon gasoline, two 4,000-gallon gasoline, one 4,000-gallon diesel, and one 1,000-
gallon kerosene USTs, associated dispensers and product piping were removed between October
5
15 and 16, 2018. A previous UST system was removed from the site on May 31, 1989 which
consisted of one 2,000-gallon gasoline and one 1,000-gallon diesel USTs.
A total of 117.25 tons of overburden soils from UST Basin #1 were transported offsite for
disposal.
Detectable concentrations of TPH-GRO and/or TPH-DRO that did not exceed the RALs were
reported in the soil samples collected from UST-1-1 (9’), UST-1-2 (9’), UST-1-3 (9’), UST-2-1
(9’), UST-2-2 (9’), UST-2-3 (9’), UST-3-1 (12’), UST-3-2 (12’), UST-3-3 (12’), UST-4-1
(12’), UST-4-2 (12’), UST-5-3 (9’), UST-6-2 (7’), DI-4 (3’) and PP-2 (3’).
Concentrations of TPH-GRO and/or TPH-DRO that exceed the RALs were reported in the soil
samples collected from UST-6-1 (7’), DI-1 (3’) and DI-3 (3’).
Based on field screening results, 22.44 tons of overburden soils and soils from below the
kerosene UST and kerosene dispenser were excavated and transported offsite for disposal.
Following over-excavation activities at the kerosene UST in Basin #2, a confirmation soil
sample (UST-6-3 (8’)) was collected at 8 feet bgs and submitted for on-site analysis by RedLab
for TPH-GRO and TPH-DRO using UVF technology. No detectable concentrations of TPH-
GRO and/or TPH-DRO were reported in the soil sample UST-6-3 (8’).
Neither ground water nor bedrock were encountered in the UST basin during excavation
activities. In addition, no free product was observed during excavation activities.
Based on this information, GRI recommends no further UST closure assessment for this facility.
