EXECUTIVE SUMMARY
The Site consists of one irregular-shaped parcel of land, totaling approximately 5.23 acres, identified as Parcel
ID Number 8903 106950. The Site is improved with one approximately 23,895-square foot automotive
dealership building and one approximately 2,944-square foot automotive detailing building. The Site is
occupied by Biggs Buick-GMC, an automotive dealership.
Petroleum-impacted soil and groundwater were discovered in 2008 during the removal of a former on-site
gasoline UST system; however, the findings were not reported to NCDEQ at the time.
Phase II assessment activities performed by EA personnel and its subcontractors in September 2022
confirmed the presence of groundwater contamination exceeding 2L Standards in the vicinity of the former
UST system.
Based on the findings of the Phase II ESA, the NCDEQ issued an Acknowledgement of Report Receipt letter
dated September 30, 2022, which required receptor survey information be provided in a Limited Site
Assessment (LSA) report.
On November 10, 2022, a Notice of Residual Petroleum, including both soil and groundwater land-use
restrictions, was recorded at the Pasquotank County Register of Deeds.
To date, no water supply wells have been identified within 1,500 feet of the source area. The nearest surface
water body, an unnamed pond, is located approximately 1,700 feet to the northeast of the source area. One
(1) school, Albemarle School, is located approximately 950 feet to the northwest of the source area.
Based on the results of this Limited Site Assessment - Phase I (LSA-I), EA offers the following conclusions:
Petroleum-impacted soil and groundwater were initially discovered during the removal of the
former UST system in 2008.
In September 2022, groundwater concentrations exceeding 2L Standards were confirmed in
the vicinity of the former UST system.
None of the target analyte concentrations exceed their respective GCLs.
No petroleum free product has been detected in on-site groundwater.
The nearest surface water body, an unnamed pond, is located approximately 1,700 feet
northeast of the source area.
To date, no water supply wells have been identified within 1,500 feet of the source area.
Municipal water service is available for all properties in the Site area.
One place of public assembly, Albemarle School, is located approximately 950 feet to the
northwest of the source area.
Based on the lack of water supply wells and other receptor information, the release appears
eligible to be classified as “Low Risk.”
A Notice of Residual Petroleum, including both soil and groundwater land-use restrictions,
was previously recorded at the Pasquotank County Register of Deeds. Therefore, the release
also appears eligible to be closed out via a No Further Action determination.
Based on the conclusions of this LSA, EA recommends the following:
Submit a copy of this report to the North Carolina Department of Environmental Quality (NCDEQ),
Washington Regional Office, Division of Waste Management, Underground Storage Tank (UST)
Program for review. The NCDEQ will ultimately determine the release risk classification and any
potential additional assessment and/or remediation actions required of the owner/responsible party of
the on-site UST system. Based on the findings of the LSA, the release appears eligible to be
classified as “Low-Risk” and closed via a No Further Action determination due to the previously
recorded Notice of Residual Petroleum.

1.0 SITE HISTORY AND CHARACTERIZATION
The Site consists of one irregular-shaped parcel of land, totaling approximately 5.23 acres, identified as Parcel
ID Number 8903 106950. The Site is improved with one approximately 23,895-square foot automotive
dealership building and one approximately 2,944-square foot automotive detailing building. The Site is
occupied by Biggs Buick-GMC, an automotive dealership. The Site is accessible via US Highway 17 South
to the northwest and Big Daddy Parkway to the southwest. The Site utilizes municipal water service provided
by the Pasquotank County Water Department. The Site utilizes septic systems located to the northeast of the
dealership building. A Site Location Map is attached as Figure 1.
The Site historically operated two 1,000-gasoline underground storage tanks (USTs). The first UST was
installed in 1974 and removed in 1992. Upon removal of the first UST, contaminated soil was removed;
however, groundwater contamination remained at the Site (Incident No. 7609). On April 20, 1992, five
groundwater monitoring wells were sampled, and one sample (MW5) contained a Benzene concentration of
1.5 micrograms per liter (ug/L), which slightly exceeded the NCAC 2L Groundwater Quality Standard (2L
Standard) of 1 ug/L for Benzene. On June 20, 1992, the five monitoring wells were resampled, and none of
the samples contained detectable concentrations of petroleum constituents. The release incident was
subsequently closed out via a Notice of No Further Action (NFA) determination on August 4, 1992.
The second UST was installed at the Site in August 1992 and removed on September 17, 2008.
Approximately 48.54 tons of contaminated soil were removed during the UST closure activities. None of the
soil samples collected from the UST basin contained detectable concentrations of Total Petroleum
Hydrocarbons (TPH) – Gasoline Range Organics (GRO) or Diesel Range Organics (DRO). However, the two
soil samples collected beneath the product lines (LB-1 and LB-2) contained concentrations exceeding TPH
Action Levels. In addition, a groundwater sample collected from a monitoring well (MW-1) contained a
concentration of Benzene (6.5 ug/L) exceeding the 2L Standard. The 2008 UST Closure Report does not
appear to have been submitted to the NCDEQ at the time.
On September 6, 2022, EA collected one groundwater sample (WS-3) in the vicinity of the soil and
groundwater contamination identified during the 2008 UST Closure, as part of a Phase II Environmental Site
Assessment (ESA). The groundwater sample contained concentrations of Benzene, Naphthalene, Toluene
and Total Xylenes exceeding 2L Standards. The location and groundwater analytical results for WS-3 are
depicted on the attached Figure 2. A copy of the Phase II ESA report was subsequently submitted to the
NCDEQ. In addition, EA obtained and submitted a copy of the prior 2008 UST Closure Report.
On September 30, 2022, the NCDEQ issued an Acknowledgement of Report Receipt letter. Based on the
findings of the 2008 UST Closure Report and 2022 Phase II ESA, the NCDEQ requested a Limited Site
Assessment (LSA) be performed at the Site. The letter indicated the groundwater data from the 2022 Phase II
ESA report could be used for completion of the LSA report. According to the letter, if the site meets the
criteria for a low risk classification based on the receptor survey information provided in the LSA Report, the
site may be eligible for site closure upon filing a Notice of Residual Petroleum, including land use restrictions
for both soil and groundwater, with the register of deeds office.

1.1 Geology and Hydrogeology
1.1.1 Regional Geology and Soil Geomorphology
Based on a review of the geologic map (North Carolina Geological Survey, 1985) of the Site vicinity, the Site
is located within the Coastal Plain Physiographic Province of North Carolina. The site area is underlain
primarily by Quaternary-aged sands, silts and clays.
Based on the USDA Web Soil Survey, http://websoilsurvey.nrcs.usda.gov/app/, dated 2022, the general soil
profile at the site consists primarily of one soil type: Hyde mucky silt loam, 0 to 2 percent slopes, (HyA).
Hyde soils typically consists of very poorly drained soil with a moderately high water capacity.
1.1.2 Topography, Surface Drainage and Regional Hydrogeology
According to the USGS Topographic Quadrangle Map of Pasquotank, North Carolina (Figure 1), the Site
elevation is approximately 10 feet above mean sea level (MSL). The topographic map indicates that the Site
slopes generally to the southeast. In the absence of any other obvious significant structural or geomorphic
drainage features, surface drainage is suspected to be influenced primarily by the surface topography.
Groundwater generally occurs as a result of infiltration of both meteoric and surface water through the
relatively permeable overburden. Fractures, joints, bedding planes and other discontinuities in the underlying
rock can affect the groundwater conditions. Site-specific groundwater flow may also be influenced by the
proximity of nearby drainage features, sinkholes, creeks, swamps, and pumped groundwater wells.
Groundwater levels and flow directions are typically site specific. In this setting, the surface of the
groundwater table is expected to be a subdued replica of the ground surface. Groundwater may occur at or
near the soil/rock interface or it may be contained within the bedrock. Based on previous groundwater data
collected at the Site, the shallow groundwater flow direction at the Site appears to be generally to the south.

2.0 SUMMARY OF SITE ASSESSMENT INFORMATION
2.1 Soil Assessment Activities – UST Closure Report and Soil Sampling (12/18/2008)
On September 17, 2008, Environmental Professionals, Inc. (EPI) oversaw the removal of the on-site gasoline
UST system. The tank dimensions were approximately 12 feet by 17 feet. The fiberglass tank was observed
to be in good condition, with no pits or holes observed. The final excavation in the UST area measured
approximately 14 feet wide by 19 feet long and a depth of 7 feet. No petroleum odors or staining were
observed in soils near the UST excavation area. Based on visual observation, the rock/gravel mixture beneath
the fuel lines were removed until native soil was encountered at a depth of approximately 4 feet. The final
excavation in the fuel line area measured approximately 5 feet wide by 22 feet long and a depth of 4 feet.
Petroleum odors and staining were noted in the soil beneath the fuel lines. Approximately 48.54 tons of
contaminated soil were excavated from the areas of the UST and fuel lines. None of the seven soil samples
collected from the bottom and sidewalls of the UST excavation area contained detectable concentrations of
TPH-GRO or TPH-GRO. However, TPH-GRO concentrations were detected in fuel line soil samples LB-1
(12.9 ppm) and LB-2 (32.9 ppm) and a TPH-DRO concentration was detected in LB-2 (16.4 ppm).
2.2 Groundwater Assessment Activities – UST Closure Report and Soil Sampling (12/18/2008)
On November 6, 2008, a groundwater monitoring well (MW-1) was installed in the area of the former UST
fuel lines, as part of the UST closure activities. The monitoring well was installed to a depth of 15 feet below
the ground surface (bgs) with a screened interval of 5 to 15 feet bgs. Laboratory analysis of groundwater
samples from MW-1 revealed a Benzene concentration of 6.5 ug/L, which exceeds the 2L Standard of 1 ug/L.
2.3 Groundwater Assessment Activities – 2022 Phase II ESA
On September 6, 2022, as part of a Phase II ESA, EA collected one groundwater sample (WS-3) in the
vicinity of the former UST system. The groundwater sample contained concentrations of Benzene,
Naphthalene, Toluene and Total Xylenes exceeding their respective 2L Standards. The location and
groundwater analytical results for WS-3 are depicted on the attached Figure 2.
2.4 Notice of Residual Petroleum – November 2022
On November 10, 2022, a Notice of Residual Petroleum, including both soil and groundwater land-use
restrictions, was recorded at the Pasquotank County Register of Deeds.

3.0 SAMPLING RESULTS
No additional soil or groundwater samples were collected during this LSA, per the NCDEQ
Acknowledgement of Report Receipt letter dated September 30, 2022.
4.0 RECEPTOR INFORMATION
On November 10, 2022, EA performed a receptor survey to identify all public water supply wells, public
water sources and wellhead protection areas located within 1,500 feet of the Site through search of municipal,
county or water district records. EA personnel also attempted to identify any unregistered or unmarked
private water supply wells within 1,500 feet of the Site, including a visual reconnaissance of the surrounding
area and a survey of property owners within 500 feet of the Site. In addition, EA personnel contacted the
Pasquotank County Water Department and the Albemarle Regional Health Services, Environmental Health
Department regarding the source of the municipal water supply, the availability of municipal water service in
the Site area and the presence of any known water supply wells in the Site area. The Receptor Survey also
included a search for surface water features within 1,500 feet of the Site and subsurface structures such as
underground utilities or basements located on-site or on adjacent properties. EA personnel also identified
areas of public assembly such as schools, parks, and churches within 1,500 feet of the Site.
To date, no water supply wells have been identified within 1,500 feet of the source area. Adjacent property
and potential receptor information is included in Table 2 and depicted on the Adjacent Property and Potential
Receptor Map attached as Figure 3.
4.1 Water Supplies
Properties in the Site area are provided municipal water primarily by the Pasquotank County Water
Department, with limited additional properties serviced by the Elizabeth City Public Works Department. The
distribution lines for the water supply are routed along adjacent road right-of-ways, including US Highway
17. EA personnel provided the Pasquotank County Water Department and the Elizabeth City Public Works
Department a list of all properties within 1,500 feet of the source area, in order to determine if municipal
water connections existed for the properties. According to the departments, municipal water service records
were found on file for the developed properties and service is available for all properties in the Site area. On
November 10, 2022, EA personnel performed a receptor survey which consisted of a visual reconnaissance of
properties within 1,500 feet of the Site. EA personnel also sent Water Supply Well Information Surveys to
property owners located within 500 feet of the Site.
To date, no water supply wells have been identified within 1,500 feet of the source area. Adjacent property
and potential receptor information is included in Table 2 and depicted on the Adjacent Property and Potential
Receptor Map attached as Figure 3.

1197 US Highway 17 South, Elizabeth City, North Carolina
Incident Number: 48685
Facility ID Number: 00-0-0000020545
EA Project No. 22-12445.3
November 21, 2022
EA personnel contacted the Albemarle Regional Health Services, Environmental Health Department
regarding water supply wells in the area. The Albemarle Regional Health Services, Environmental Health
Department database contains water supply well information dating back to 2007. EA personnel provided a
list of all properties within 1,500 feet of the source area in order to determine if well permits existed for the
properties. No water supply well permits or records were found on file for any of the properties. Adjacent
property and potential receptor information is included in Table 2 and depicted on the Adjacent Property and
Potential Receptor Map attached as Figure 3. Copies of the water supply well information surveys are
attached as Appendix A.
4.2 Surface Water
The nearest surface water body is an unnamed pond, located approximately 1,700 feet northeast of the source
area of release (Figures 1 and 3).
4.3 Wellhead Protection Areas
At the time of this investigation, no designated wellhead protection areas, as defined in 42 USC300h-7(e), are
reported to exist within 1,500 feet of the source area.
4.4 Deep Aquifers in the Coastal Plain Physiographic Province
Based on a review of the geologic map (North Carolina Geological Survey, 1985) of the Site vicinity, the
source area is located within the Coastal Plain Physiographic Province of North Carolina. The Site does not
appear to be located in an area where there is recharge to an unconfined or semi-confined deep aquifer
currently being utilized as a drinking water source.
4.5 Subsurface Structures
No basement is present at the Site. No underground utilities were identified in the general area of the source
area. Subsurface utilities are located along adjacent road right-of-ways. In addition, potential for vapors to
infiltrate the building appear minimal due to the lack of underground utilities in the area of identified
groundwater contamination, the concrete and asphalt capped surface, ventilation of the building via opening
of service area bay doors during business operations, and the fact that no vapors have been previously
reported.
4.6 Land Use
According to the Pasquotank County Planning Department, the Site is zoned as Commercial (C-1). Properties
in the surrounding area of the Site are primarily commercial, agricultural, residential and institutional in
nature. General land use information is depicted on the Land Use Map attached as Figure 4.

RISK CLASSIFICATION
AND
LAND USE FORM
Limited Site Assessment Risk Classification and Land Use Form
Part I – Groundwater/Surface Water/Vapor Impacts
High Risk
1. Has the release contaminated any water supply well including any well used for non-drinking purposes? NO
2. Is a water supply well used for drinking water located within 1,000 feet of the source area of the release? NO
3. Is a water supply well not used for drinking water (e.g., irrigation, washing cars, industrial cooling water,
filling swimming pools) located within 250 feet of the source area of the release? NO
4. Does groundwater within 500 feet of the source area of the release have the potential for future use (there is
no other source of water supply other than the groundwater)? NO
5. Do vapors from the release pose a threat of explosion because of accumulation of the vapors in a confined
space or pose any other serious threat to public health, public safety or the environment? NO
If yes, describe.
6. Are there any other factors that would cause the release to pose an imminent danger to public health, public
safety, or the environment? NO
If yes, describe.
Intermediate Risk
1. Is a surface water body located within 500 feet of the source area of the release? NO
If YES, does the maximum groundwater contaminant concentration exceed the surface water quality standards
and criteria found in 15A NCAC 2B .0200 by a factor of 10?
2. Is the source area of the release located within an approved or planned wellhead protection area as defined
in 42 USC 300h-7(e)? NO
If yes, describe.
3. Is the release located in the Coastal Plain physiographic region as designated on a map entitled “Geology of
North Carolina” published by the Department in 1985? YES
If YES, is the source area of the release located in an area in which there is recharge to an unconfined or
semi-confined deeper aquifer that is being used or may be used as a source of drinking water? UNKNOWN
If YES, describe.
The source area does not appear to be located in an area where there is recharge to an unconfined or semi-
confined deep aquifer currently being utilized as a drinking water source.
4. Do the levels of groundwater contamination for any contaminant exceed the gross contamination levels
(See Table 2.) established by the Department? NO
Part II - Land Use
Property Containing Source Area of Release
The questions below pertain to the property containing the source area of the release.
1. Does the property contain one or more primary or secondary residences (permanent or temporary)?
NO
The property does not contain any residences.
2. Does the property contain a school, daycare center, hospital, playground, park, recreation area,
church, nursing home, or other place of public assembly? NO
The property exists as an automotive dealership. The nearest place of public assembly is Albemarle
School, located approximately 950 feet northwest of the source area.
3. Does the property contain a commercial (e.g., retail, warehouse, office/business space, etc.) or
industrial (e.g., manufacturing, utilities, industrial research and development, chemical/petroleum
bulk storage, etc.) enterprise, an inactive commercial or industrial enterprise, or is the land
undeveloped? YES
The property is currently an active commercial enterprise.
4. Do children visit the property? YES
The Site is an automotive dealership. It is possible children visit the property.
Is access to the property reliably restricted consistent with its use (e.g., by fences, security personnel or
both)? NO
Access to the property is not restricted.
5. Do pavement, buildings, or other structures cap the contaminated soil? YES
Pavement, concrete and the Site building cap the area of contaminated soil.
If yes, what mechanisms are in place or can be put into place to ensure that the contaminated soil will
remain capped in the foreseeable future?
The source area is likely to remain capped since it is covered by the Site building and pavement utilized for
vehicle drive areas. In addition, a Notice of Residual Petroleum has been recorded at the Pasquotank County
Register of Deeds, which includes land-use restrictions limiting exposure to the contaminated soil.
6. What is the zoning status of the property?
Commercial
7. Is the use of the property likely to change in the next 20 years? NO
The use of the property is unlikely to change. The Notice of Residual Petroleum recorded at the Pasquotank
County Register of Deeds restricts the Site to commercial/industrial use only.
