70 WEST BP SITE
6200 Glenwood Avenue
Raleigh, Wake County, North Carolina
April 9, 2021
1.0 INTRODUCTION
The site is the 70 West BP located at 6200 Glenwood Avenue near Raleigh, Wake County, North
Carolina (Drawing 1). Five tanks were used at the site to store petroleum product (Drawing 2).
Two tanks were 10,000 capacity tanks (T-1 and T-4) and were used to store gasoline and diesel
product. The tanks measured 32 feet long and eight feet in diameter. Two tanks were 8,000
capacity tanks (T-2 and T-3) and were used to store gasoline product. The tanks measured 25
feet long and eight feet in diameter. Tank 5 was a 4,000 capacity tank and was 24 feet long
and five feet in diameter and previously used to store diesel. The tanks were fiberglass and in
good condition and were removed on February 23 and 24, 2021.
It is our understanding soil impact was identified in at the site as a result of an environmental
investigation in 1993. The release was assigned UST Incident 10421. A no further action letter
was issued in 2006 for the incident.
2.0 UST CLOSURE AND INTIAL ABATEMENT ACTIVITIES
Prior to tank removal, a permit to remove the five tanks was obtained from the City of Raleigh.
In addition, an UST 3 Notice of Intent form was sent to the NC UST Section in January 2021
(see Appendix A). On March 18, 2021, an UST 2 form was sent to the NC UST Section’s
Permitting Branch via email.
The bulk of the petroleum product was removed by others prior to between February 8 and 11,
2021. Between February 15, 2021 and February 17, 2021 steps were taken to remove the
dispensers and lines associated with the tanks. After the petroleum product had been removed
from the tanks by others, steps were taken to pressure wash the interior of the tanks and
simultaneously inert the tanks on February 23, 2021. Subsequent to approval from the City of
Raleigh Fire Marshall, the tank removal activities commenced on February 24, 2021. Oakes then
began the removal of the 4,000 gallon kerosene and 10,000 gallon diesel USTs. The remaining
USTs were then removed accordingly. Soils above and around the sides of the tanks were
removed using a track-hoe. Limited petroleum odors were noted during the removal process.
The excavation for the tanks measured approximately 60 feet long by 38 feet wide and 11 feet
deep.
Once the tanks, product lines and dispensers were removed, soil samples were collected from
beneath the tank locations (Drawings 3). The samples for the USTs are as follows: S1-1, S1-2,
S1-3, S1-4, S2-1, S2-2, S2-3, S3-1, S3-2, S3-3, S4-1, S4-2, S4-3, S4-4, S5-1, S5-2 and S5-3.
The samples for the product lines are as follows: LS-1 thru LS-17. The samples for the
dispensers are as follows: DS-1, DS-2, DS-3, DS-4, DS-5, DS-6 and DS-7. Soil samples were
submitted to Cohesion for the analysis of TPH as diesel (DRO) and TPH GRO according to EPA
Method 3550 and 5035 using the state approved Ultraviolet Fluorescent analytical technology.

Phase I Limited Site Assessment April 9, 2021
70 West BP Site Page 2
Regarding the 41 closure samples collected for the USTs, product lines and dispensers, TPH
concentrations were detected in six soil samples (DS-7, LS-2, S1-3, S5-1, S5-2 and S5-3) above
the North Carolina UST Sections cleanup value of 50 milligrams per kilogram (mg/kg) for gas
and/or 100 mg/kg for diesel.
TPH as gas was identified at concentrations of 50.8 mg/kg (LS-2), 99.5 mg/kg (S1-3), 270
mg/kg (S5-1) and 193 mg/kg (S5-2). In addition, TPH as diesel was identified at concentrations
of 114 mg/kg (DS-7), 307 mg/kg (S1-3), 2,314 mg/kg (S5-1), 471 mg/kg (S5-2) and 284 mg/kg
(S5-3).
Based on the presence of TPH as GRO and/or DRO in the above mentioned soil samples the
submitted samples were analyzed according to approved analytical methods to determine
concentrations of compounds which comprise gasoline and or diesel. In addition the samples
were analyzed for the presence of volatile petroleum hydrocarbons (VPH) and/or extractable
petroleum hydrocarbons (EPH).
Soil sample LS-2 was analyzed for volatile organic compounds (VOCs) according to SW-846
Methods 8260 and VPH. Soil samples S1-3, S5-1 and S5-2 were analyzed for VOCs, semi VOCs
(SVOCs) according to SW 846 Method 8270 and VPH/EPH. The remaining soil samples DS-7 and
S5-3 were analyzed for SVOCs and EPH. Based on the analytical results no VOCs, SVOCs and/or
VPH/EPH were detected at a concentration in excess of the Soil-to-Groundwater Maximum Soil
Contaminant Concentration (MSCC), except the following. EPH compounds were detected above
the soil-to-groundwater MSCCs in soil samples DS-7, S5-1 and S5-3, but were below the
residential MSCCs.
Based on the soil confirmation analytical results, Phase I Limited Site Assessment (LSA)
activities have been performed at the site. The results of the Phase I LSA are presented below.
3 RECEPTOR SURVEY
The following details the results of the receptor survey conducted in March and April 2021. A
completed Risk Classification and Land Use Form is attached in Appendix A.
3.1 Water Supply Wells
MSE personnel visited the site on March 31, 2021 to determine the location of water-supply wells
within a 1,500-foot radius of the site. A visual survey was conducted by Mr. Evan Pollard to locate
well houses and water meters. Letters were mailed to property owners within a 500-foot radius of
the site and adjoining property owners (Appendix A).
Based on the limited survey responses and site visit, MSE confirmed that no water-supply wells are
located within 1,000 feet of the source area.
3.2 Public Water Supply
City water supply is available to all residents and businesses in the area.

3.3 Surface Water
According to the USGS topographic map of the site (Drawing 1), an unnamed creek is located
northeast of the site and a large creek is located to the north and east. The closest surface water
feature is located approximately 900 to 1,000 feet northeast of the site.
3.4 Wellhead Protection Areas
According to the North Carolina Division of Public Health, Public Water Supply Section (Public
Water Supply) website, there is one wellhead protection plans currently approved for Wake
County in Rolesville, North Carolina and is not within 1,500 feet of the site.
3.5 Coastal Plain Physiographic Province
According to the Geologic Map of North Carolina (1986), published by the North Carolina
Department of Environment and Natural Resources, the site is not in the Coastal Plain
Physiographic Province.
3.6 Subsurface Structures
Underground utilities, including water, electrical, and product lines are present on the site.
3.7 Surrounding Land Use
Nearby properties are used for commercial and residential purposes. MSE has prepared a map
showing the adjacent parcels and their associated parcel numbers (Drawing 3). Table 1
summarizes the contact information for the owners of these adjacent parcels.
4 SITE GEOLOGY AND HYDROGEOLOGY
Shallow soils consist of tan sandy silt to 30 feet below land surface (BLS). Hard rock was
encountered from 30 feet BLS to 80 feet BLS during well installation activities. No water was
present in the temporary monitoring well after an extended period of time.
5 SOIL AND GROUNDWATER INVESTIGATION
5.1 Soil Sampling Activities
On March 25, 2021, an attempt to install a temporary well at the site was conducted. The
boring was advanced to 30 feet using direct-push technology. At 30 feet rock was encountered
and the boring could not be advanced further and water was not present after a period of time.
To determine the concentrations of chemical specific compounds at monitoring well TW-1, two
soil samples (TW-20 and TW-30) were collected from the boring at a depth of 20 and 30 feet
BLS. The 10 foot depth samples were collected and analyzed at the time of the UST removal
activities. The soil samples were placed in pre-labeled laboratory provided glassware, packed on
ice, and transported under chain-of-custody protocol to Environmental Conservation
Laboratories (ENCO), of Cary, North Carolina. Soil sample TW-20 collected from the TW-1
boring was analyzed for the presence of volatile petroleum hydrocarbons (VPH) and extractable
petroleum hydrocarbons (EPH) according to MADEP method. While soil sample TW-30 collected

FLAGS/NOTES AND DEFINITIONS [TOC_1]Flags/Notes[TOC]
The sample was analyzed at dilution.
The analyte was detected in the associated method blank.
The reported value is between the laboratory method detection limit (MDL) and the laboratory method
reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable.
The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation
data and moisture content, where applicable.
The concentration indicated for this analyte is an estimated value above the calibration range of the
instrument. This value is considered an estimate.
Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQL) and is
based on the low point of the calibration curve, when applicable, sample preparation factor, dilution
factor, and, in the case of soil samples, moisture content.
