Re: Request for State Lead Acceptance for the
Former Exxon Service Station located at
957 and 961 S. Fayetteville Street, Asheboro, NC 27203
DEQ Incident # Pending
Mr. Whitmire,
As requested by Tom Kemp, the brother of Phil Kemp the property owner, Pyramid
Environmental & Engineering, PC (Pyramid) prepared this letter to request acceptance for
the former Exxon Service Station site into the State Lead Program. The former Exxon
Service Station was owned and operated by Exxon prior to purchase by Phil & Anna Kemp
in 1985. The site history and supporting documentation for this State Lead Program
eligibility request is presented herein.
Service Station History
In 2018, Pyramid performed a Phase II Environmental Site Assessment (ESA) to research
the property and identify and Recognized Environmental Conditions (RECs) for the site.
The Phase I ESA was also prepared to support a property transaction being considered by
the property owner. The Phase I ESA was completed for the property owner Mr. Phil
Kemp who passed away August 23, 2018. The Phase I ESA was completed in June 2018,
and was submitted to Ms. Andria Merritt of the NCDEQ Orphaned Tank Program to see if
the site would qualify for acceptance in the Orphaned Tank Program. After consideration,
the site was not accepted and additional work was authorized for soil assessment.
Review of the Phase I ESA showed that there were two gasoline product dispenser islands
connected to Underground Storage Tanks (USTs) located south of the dispenser islands.
The following table presents a brief review of important dates and actions.

Date Site Description / Activity
1957 Previous small wooden building demolished on the property
1963 The current Service Station buildings were constructed
1964‐1983 Hammond Esso Service Station & Gene’s Exxon Station operated.
1984 The Exxon USTs were removed by the UST Owner/operator in 1984.
Deed research indicated that Humble Oil Co. (Merged with Exxon in
1973) was the owner/operator of the USTs that were removed in 1984.
1984 The Exxon in‐ground hydraulic lifts were not removed by Exxon and
were covered with steel plates.
05‐06‐1985 Phil & Anna Kemp purchased the property to use for auto sales. Phil
Kemp installed and operated an aboveground hydraulic lift in the
garage. The aboveground lift was eventually sold to the tenant and
removed from the garage in 2017.
1985‐1997 A 1,000‐gallon gasoline UST was installed by Phil Kemp, and used to fuel
private vehicles. The tank was pulled in 1997 and the UST‐12 report
showed no contamination. The UST‐12 report was submitted to the
NCDENR. Light auto repair and detailing was completed on site
associated with the primary activity which was auto sales.
1997‐2017 Auto sales and light repairs to cars were completed on site. The
operations were shut down at the end of 2017.
June 2018 The Phase I ESA and Orphaned Tank Program Acceptance letter were
prepared and sent to the NCDEQ.
May 2019 After many calls, the NCDEQ orphaned tank program ruled that the
State Lead Program would be a more appropriate place to seek
eligibility. A Phase II ESA was planned and completed to provide data
of petroleum contamination, if any were present.
The Phase I ESA includes the deed records and was previously transmitted to the NCDEQ
and is not attached to this submittal. The Phase II was completed to investigate the most
likely areas of contamination from the Exxon Service Station operations.

UST & AST Information
The former Exxon Service station was located at 957 & 961 S. Fayetteville Street in
Asheboro, Randolph County, NC. The site location is shown on Figure 1, and other maps
from the Phase I show the surrounding property owners and property use.
Figure 1 ‐ Topographic Map
Figure 2 ‐ Tax Map of the site
Figure 3 ‐ 2014 Aerial Photo with Notes
The site detail map (Figure 4) shows the location of the former Exxon gas station USTs,
gasoline dispenser islands, and the Exxon in‐ground hydraulic lift locations. An empty and
disconnected heating oil aboveground storage tank (AST) is indicated on Figure 4. In 2018
two drums were located on site, which were removed prior to the work in 2019. The
automotive tires and remaining parts inside the building were also removed in early 2019.
The size and contents of the previous Exxon gasoline USTs are unknown.
There were three gasoline dispensers located on each pump island suggesting that
there were three USTs associated with the former Exxon gasoline station.
The two Exxon in‐ground hydraulic lifts are located in the service bays and were
only used by Exxon. Each hydraulic lift holds about 40‐50 gallons of hydraulic oil.
The in‐ground hydraulic lifts were last used by Exxon in 1984.
Phil Kemp installed and operated one aboveground hydraulic lift in the garage.
The lift was sold to the tenant and removed from the garage in 2017.
A 275‐gal. heating oil AST is located behind the building, and contained no fluids.
The 55‐gallon drums were removed by the tenant in early 2019 as he moved out.
Previous Environmental Assessment Activities
In 1997, a 1,000‐gallon gasoline UST system that was used to fill private vehicles was
removed by Mr. Phil Kemp. The UST‐12 report was prepared and sent to the NCDENR.
The UST‐12 report showed no impacts of petroleum at the UST system.
Current Site Use
The property is unused and there is a pending real estate transaction. The Phase I and
Phase II assessments were completed to provide the NCDEQ with information to support
the State Lead request. The surrounding area is entirely commercial along South
Fayetteville Street, with a few residential properties uphill of the site. The City of
Asheboro has provided water supply to the area surrounding the site since the 1960’s.
No water supply wells were seen in the area of the site. No official receptor survey was
completed, but it is expected that all properties in the area are connected to City water.

Geophysical Investigations ‐ 2019
As part of the UST assessment for the site, Pyramid recommended scanning the entire
property for unknown USTs and subsurface utilities. Since the site had reportedly been
cleared of USTs before Phil Kemp purchased the property, this was a precaution which
would detect any unknown Exxon USTs. The Geophysics was completed on the property
and no unknown USTs were located. The Geophysical report and map of the
Electromagnetic data are presented in Attachment A.
Phase II Environmental Assessment ‐ 2019
After completing the Geophysical investigations, Pyramid planned for the soil assessment
at the most likely locations to detect petroleum compounds in the soil at the former
service station. The boring locations targeted the specific areas listed below.
GP‐1 thru GP‐6 Investigated former Exxon gasoline dispenser locations
GP‐6A thru GP‐10 Investigated former Exxon Gasoline UST area
GP‐11 Investigated the former heating oil AST area
GP‐12 and GP‐13 Investigated former Exxon in‐ground hydraulic lifts
The soil boring assessment was scheduled for June 18, 2019. The standard procedures
used are summarized in Attachment B. The soils were screened in the field using a
calibrated Photoionization Detector (PID). After each soil boring, a decision was made
whether to analyze soil from that boring depending on the PID readings and observed
petroleum odor. Eleven ( 11 ) soil samples were selected for laboratory analyses from
the Geoprobe™ borings.
The selected soil samples were submitted for laboratory analyses at Red Lab, LLC in
Wilmington, NC. The soils were shipped FedEx under standard Chain‐of‐Custody (COC)
procedures, and were analyzed using the Ultra‐Violet Fluorescence (UVF) method and
reported Gasoline Range Organics (GRO) and Diesel Range Organics (DRO). The Red Lab
analytical laboratory report for the soil is presented in Attachment C. The analytical
results are summarized in the following table.

Based on the laboratory analytical results, the soil samples from the dispenser island were
quite low and were below the action levels for the NCDEQ.
The tank pit was investigated using five soil borings. In several borings Pyramid observed
jumbled fill material indicating that we were in the formerly excavated area. For GP‐7,
the UST backfilled material was sampled at 8‐10 feet BLS and a concentration of 109.5
milligrams per kilogram (mg/kg) of DRO was detected. This level of contamination is just
above the NCDEQ Action level for DRO of 100 mg/kg which is a reportable concentration
of petroleum in the Exxon UST excavation at 8‐10 feet. Pyramid continued the soil boring
to a depth of 13 – 14 feet where undisturbed (Native) soil was encountered and collected
an additional soil sample for laboratory analysis. The results of the deeper soil sample
showed concentrations reduced to below the NCDEQ Action levels.

Pyramid Environmental & Engineering, PC – 2019‐188 07‐21‐2019
At the former heating oil AST, a single soil boring was completed in the area most likely
to show contamination. The soil boring showed no contamination above the NCDEQ
action levels at the AST.
The former Exxon Service Station in‐ground lifts were uncovered by removing the steel
plate from over the lifts. Each lift was investigated by installing a soil boring near each in‐
ground hydraulic lift. The results of GP‐12 (next to Lift # 1 ‐ the northern lift) showed 27.3
mg/kg GRO and 517.6 mg/kg DRO. The DRO result from this soil sample was above the
regulatory standard of 100 mg/kg. The final Geoprobe sample GP‐13 was collected at 8‐
9 feet next to Lift # 2 (the southern lift). The analytical results of GP‐13 showed both GRO
(211.7 mg/kg) and DRO (6402 mg/kg) concentrations greater than the NCDEQ regulatory
action levels.
Conclusions
Based on the assessment completed to date, the following statements can be made:
The former Exxon Service Station operated from 1964 to 1983, and the gasoline
USTs were removed in 1985. The Exxon USTs were removed prior to Phil Kemp’s
ownership; however, the Exxon in‐ground lifts remained in the garage area. The
Exxon in‐ground hydraulic lifts were covered with steel plates and were no longer
used after 1984.
Pyramid completed a Geophysical investigation to investigate for unknown USTs
and no tanks were found. The investigation also marked utilities prior to
environmental drilling.
The soil assessment at the dispensers showed low levels of petroleum
contaminants in soil at concentrations well below the NCDEQ Action Levels.
The soil assessment at the former Exxon gasoline UST area showed levels of
petroleum at concentrations greater than the NCDEQ Action Levels at GP‐7.
The deeper soil sample at the same location showed no contaminants at 13‐14
feet suggesting a limited contamination profile.
The soil assessment at the former heating oil AST showed no release.
The Exxon in‐ground lifts were not used after 1984, and both of the lifts showed
petroleum contamination.
