Incident Number: 7121
Risk Classification: Intermediate
Dear Mr. Mao,
Arcadis G&M of North Carolina, Inc. (Arcadis) has prepared this Soil Removal Action Report on behalf of
Piedmont Natural Gas Company, Inc. (PNG), to present the results of the planned soil removal action activities
completed in May and June 2022 at the Former PNG Operations Center located at 1029 Winston Street in
Greensboro, Guilford County, North Carolina (the site). The site is approximately 1.55 acres in size and historical
operations included fueling and maintenance activities associated with PNG’s service vehicles. The site is
currently owned by The North Carolina A&T Real Estate Foundation, Inc., and is zoned as Industrial. A Site
Location Map and Site Layout Map are presented as Figure 1 and Figure 2, respectively.
The purpose and objective of these soil removal action activities was to address residual benzene impacts
upgradient and around monitoring well MW-3 and residual naphthalene impacts in areas exceeding the
Industrial/Commercial soil cleanup level (SCL). The completed remedial activities are described in greater detail
below. The soil removal action activities were performed in accordance with Work Plan for Soil Removal Action,
dated January 28, 2022. Recommendations including the establishment of an optimized monitoring well network,
abandonments of select monitoring wells, and quarterly performance groundwater monitoring and sampling are
also provided.
SITE BACKGROUND
A petroleum release was discovered at the site in August 1990 during removal of two gasoline underground
storage tanks ([USTs] one 3,000-gallon and one 6,000-gallon) located in a tank pit (Figure 2) near the service
operations center and one diesel UST (500-gallon) located in a separate tank pit to the southwest. The two initial
tank pit excavations were conducted to a depth of approximately 16 feet below ground surface (bgs) and 8.5 feet
bgs, respectively. The analytical results of the soil samples collected from around the diesel UST pit did not report
detectable concentrations of diesel range hydrocarbons. The post-excavation soil samples collected from the
gasoline UST pit indicated concentrations of adsorbed-phase hydrocarbons ranging from 690 parts per million

(ppm) to 6,600 ppm; more than the North Carolina action level at the time of 10 ppm. The gasoline UST pit was
then over-excavated to a depth of 20 feet bgs and additional soil samples were collected which indicated a total
petroleum hydrocarbon result of 810 ppm. The total volume of the soils excavated and disposed of for both tank
pit excavations was approximately 550 cubic yards (CY).
No private or public water supply wells have been identified within a 1,500-foot radius of the source area. Muddy
Creek, a Class WS-V surface water body, is located approximately 350 feet west of the source area. The site is
classified as “Intermediate” risk due to the presence of the surface water body within 500 feet of the source area
and the presence of dissolved-phase constituents of potential concern (COPC) at the site above the North
Carolina Gross Contamination Level (GCL) Standard. As Muddy Creek is a Class WS-V water body, dissolved
phase COPC are also compared to the North Carolina 15A NCAC 2B Surface Water Standards.
Land Use Classification as described in 15A NCAC 02L .0408 (1) indicate this site should be classified as
Industrial/Commercial because exposure to the petroleum constituents in soil is limited in time due to the use of
the site and does not involve exposure to children.

REMEDIATION GOALS
The remediation goals for soil and groundwater are described in 15A NCAC 02L .0408 and 15A NCAC 02L .0407,
respectively. However, 15A NCAC 02L .0409 also describes procedures for cleaning up soil and groundwater to
alternate standards at intermediate and low risk sites if notification is made to the local Health Director and the
chief administrative officer of the political jurisdiction in which the site is located and all property owners and
occupants within or contiguous to the area where impacted soil and groundwater are located or where impacted
groundwater is expected to migrate. An overview of current remediation goals and/or alternate standards for soil
and groundwater are described below.

Soil
The current remediation goals for petroleum constituents in soil at intermediate risk sites are levels equal to or
less than the lowest Maximum Soil Contaminant Concentrations; however, cleanup to alternate standards can be
proposed. According to North Carolina General Statue (G.S) 143B-279.9, the unrestricted use standard for soil
impacted by a petroleum release is defined as soil impacts below the Residential SCL established in 15A NCAC
02L.0411. Although Residential SCL is the unrestricted use standard, since the site is classified as Industrial,
zoned as Industrial, and surrounded by Industrial or commercial properties, the Industrial/Commercial SCL is
proposed as the alternate standard at the site.

Groundwater
The remediation goals for groundwater at intermediate risk sites are levels equal to or less than the GCL
established in 15A NCAC 2L .0406. Additionally, groundwater must be cleaned up to levels that are sufficient to
prevent petroleum constituents associated with this site from causing a violation of the surface water rules
contained in 15A NCAC 02B. As indicated during historical surface water sampling activities, no impacts to
surface water due to this release have been identified.

SOIL REMEDIAL ACTIVITIES SUMMARY
As noted above and within previous discussions with the County, the primary remedial effort to attain closure at
the site is to address continued benzene detections above GCL in monitoring well MW-3. At the request of the
County and following agreement by Duke, Arcadis completed site investigations in 2021 which identified residual
source mass downgradient of the former gasoline UST area and in the proximity of monitoring well MW-3.
Additionally, residual naphthalene concentrations were identified in two distinct areas above the
Industrial/Commercial SCL. To address continued benzene detections above GCL at monitoring well MW-3 and
residual naphthalene in soil above Industrial/Commercial SCL, Arcadis proposed limited source area soil

excavation in areas identified during the 2021 investigation activities and as described in Work Plan for Soil
Removal Action, dated January 28, 2022. The soil excavation boundary was based on the footprint of
naphthalene determined by 2021 investigation activities and included areas immediately adjacent and upgradient
of monitoring well MW-3 to address residual benzene leaching from soil to groundwater. The limits of the
excavation are shown on Figure 3.
Prior to beginning soil excavation activities, a North Carolina 811 call was completed, and a private utility locator
was utilized to locate and mark subsurface utilities within and in proximity to the proposed excavation boundaries.
Arcadis also worked with local utility providers to re-route existing utilities (i.e., natural gas and electrical) outside
of the excavation boundary to allow access and prevent damage to existing infrastructure. Additionally, select
monitoring wells (MW-1, MW-3, MW-4, MW-6, MW-11D, and an unknown monitoring well (MW-UNK)), within or
adjacent to the proposed excavation boundary, were then abandoned prior to construction activities in
accordance with NCAC 15A 02C.0100 regulations. Well Abandonment Records documenting the abandonment of
the select monitoring wells are provided in Attachment 1.
The soil excavation was completed utilizing an excavator and other earth moving equipment. The excavation
targeted removal of impacted soils to the top of bedrock or upon encountering groundwater. The exact depth of
excavation was determined in the field based on the depth of bedrock encountered, visual observations, and soil
screening results. Excavation depths ranged from 16 to 19 feet below ground surface (bgs), predominantly at the
top of bedrock as minimal groundwater was encountered. Approximately 3,944.0 tons of excavated soil was
transported offsite for disposal at the Earth Tec Soil System in Bear Creek, North Carolina. Waste tracking
information is provided in Table 1 and waste disposal manifests are included as Attachment 2.
Arcadis collected seven confirmation soil samples from the excavation sidewalls as excavation activities
progressed to completion. Arcadis submitted the samples to Pace Analytical Services, LLC of Huntersville, North
Carolina for analysis of benzene, toluene, ethylbenzene, and xylenes (BTEX), naphthalene, and methyl-tert-butyl
ether (MTBE) by United States Environmental Protection Agency (USEPA) Method 8260B. All analytes in
samples collected and analyzed were below their respective Industrial/Commercial SCLs and only one constituent
in one sample, naphthalene in SS-05 was above the Residential SCL. Naphthalene was detected in sample SS-
05 at a concentration of 8,040 micrograms per kilogram (µg/kg). The Residential and Industrial/Commercial SCLs
for naphthalene are 5,500 and 27,000 µg/kg, respectively. Confirmation sampling results are provided in Table 2
and sample locations are shown on Figure 4. Confirmation sampling analytical reports are provided in
Attachment 3.
As shown on Figure 3 and Figure 4, Arcadis performed slot trenching in the northernmost portion of the
excavation. In the Slot Trenching Area, the excavation was backfilled to 1 foot below ground surface with
excavatable flowable fill. Following 24 hours of cure time, clean imported fill was then placed and compacted to
reach final grade. Across the remainder of the excavation area, gypsum was commingled with number 57 stone to
enhance bioremediation of residual petroleum hydrocarbons in groundwater or saturated soil. The number 57
stone backfill was used to approximately 6 feet below ground surface followed by a geotextile to provide stability
and prevent infiltration of fines. Clean imported fill was then placed and compacted in 8-inch lifts to reach final
grade. Crusher run stone or grass seed were placed on the final grade across the site as final surface coverage to
match existing conditions.
CONCLUSIONS
Arcadis completed a soil excavation to remove residual source mass targeting areas with naphthalene
concentrations above Industrial/Commercial SCLs and adjacent and upgradient of monitoring well MW-3. Arcadis
excavated approximately 3,944.0 tons of impacted soil and transported it to the Earth Tec Soil System in Bear
Creek, NC for disposal. Arcadis completed confirmation soil sampling at seven locations around the sidewalls of
the excavation and all results were below Industrial/Commercial SCLs with only naphthalene at sampling location

SS-05 above the Residential SCL. The excavated area was then backfilled with flowable fill, gypsum, stone, and
clean fill to meet existing grades.

RECOMMENDATIONS
Arcadis proposes an optimized site monitoring well network to monitor site groundwater conditions. To optimize
the site monitoring well network, Arcadis proposes to retain monitoring wells MW-2, MW-8, MW-13, MW-18, and
MW-32, while additionally reinstalling monitoring well MW-3, located within the excavation boundary, as MW-3R.
The optimized monitoring well network including the reinstalled monitoring well MW-3R and retained monitoring
wells MW-2, MW-8, MW-13, MW-18, and MW-32 is included in Figure 5. Once the new well network has been
established, Arcadis proposes to complete groundwater sampling on a routine basis until establishing that COPCs
in groundwater are equal to or less than the GCLs and will not cause a violation of the surface water rules
contained in 15A NCAC 02B. Arcadis anticipates that a Notice of Residual Petroleum (NRP) will then be filed with
the Register of Deeds in Guilford County, North Carolina.
Following establishment of the optimized monitoring well network, Arcadis proposes abandonment of remaining
monitoring wells across the site. All downgradient and side-gradient saprolite wells located offsite that Arcadis
does not propose to retain in the optimized monitoring well network have not had detections above the GCLs
since 2001. Downgradient and side-gradient monitoring wells proposed for abandonment include MW-7, MW-9,
MW-15, MW-16, MW-19, MW-25, MW-37, MW-38, MW-39, MW-41, MW-42, MW-43, MW-44, and MW-45. Also,
as previously discussed with Guilford County personnel, municipal drinking water is provided by the City of
Greensboro. Therefore, Arcadis does not recommend additional bedrock groundwater monitoring and
recommends abandonment of the following bedrock groundwater monitoring wells: MW-5, MW-10, MW-12, MW-
14D, MW-17D, MW-20D, RH-21D, RH-22D, RH-23D, MW-24D, RH-26D, MW-27D, MW-28M, MW-28D, RH-29D,
MW-30D, MW-33D, MW-34, MW-35D, MW-36D, MW-46D, MW-47M, MW-47D, and MW-48D. The BTEX,
naphthalene, and MTBE results from the four most recent groundwater samples collected from each of the
monitoring wells Arcadis proposes to abandon are included as Table 3. Monitoring wells will be permanently
abandoned in accordance with NCAC 15A 02C.0100 regulations and a permit will be requested from Guilford
County. Abandonment will include removing the well surface completion and emplacing bentonite within the
saturated portion of the well and cement grout to the surface. The details of the monitoring well installation,
monitoring well abandonment activities, and groundwater monitoring event will be documented in a Groundwater
Monitoring Report to be submitted to Guilford County for review and approval.

DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL - Adjusted Method Detection Limit.
PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean-Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as
"Total" may vary slightly from the sum of the reported component parameters.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.
TNI - The NELAC Institute.
ANALYTE QUALIFIERS
Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.M1
Analyte recovery in the matrix spike was outside QC limits for one or more of the constituent analytes used in the
calculated result.MS
The lab does not hold NELAC/TNI accreditation for this parameter but other accreditations/certifications may apply. A
complete list of accreditations/certifications is available upon request.N2
