Release Information: In July 2015, ECS was contracted by Mr. Eddie Krusch to close by
removal the heating oil underground storage tank (UST) at the ATCO property at 2806
Patterson Street, Greensboro, North Carolina. The UST consisted of one 2,000-gallon fuel oil
UST. Following receipt of the laboratory analytical data, a release of petroleum was detected
beneath the UST. The amount product lost is not known. Following removal of the UST
system, approximately 90.75 tons of impacted soil was removed for off -site treatment. A
gasoline UST of unknown size was removed from the site in the past. Sample analysis in the
area of the gasoline UST detected total petroleum hydrocarbons above state action levels. A
diesel UST was reportedly removed from the site in the past, though this could not be
confirmed. Soil samples collected and analyzed in the area of the suspect diesel UST did not
detect TPH above state action levels.

1.0 SITE HISTORY
The site is the former ATCO Rubber Products, Inc. (ATCO) facility located at 2806 Patterson
Street in Greensboro, Guilford County, North Carolina (Figure 1 and Figure 2). Based on the
records search, site reconnaissance and interviews, the building was originally constructed as a
potato chip manufacturing facility. The potato chip manufacturing business operated at the site
until the early 1980s. The building was reportedly vacant for several years. In the mid-1980s,
ATCO moved into the building. ATCO reportedly manufactured flexible ductwork. There was is
no evidence that hazardous chemicals were used at the site by ATCO.
There was no evidence that underground storage tanks (USTs) were registered at the subject
site with the North Carolina Department of Environment and Natural Resources (NCDENR).
However, our review of records at the Greensboro Safety and Fire Prevention Bureau identified
documentation of several petroleum USTs that were previously located at the site. During our
site reconnaissance, an area north of the building contained a concrete area, adjacent to the
asphalt pavement. This area is believed to be the former location of a diesel UST. A former
gasoline UST was located near the northwest corner of the warehouse and a 2,000 gallon
heating oil UST was located south of the warehouse, near the former boiler room. These USTs
were considered recognized environmental conditions (RECs).
Two properties (former Chemical & Solven- and former Ashland Chemical) that previously
contained chemical manufacturing/storage cilities are located on adjoining properties east of
the site. Based on proximity, the releases -om these properties were considered RECs of the
site. Based on proximity and groundwater flow direction inferred from the surface topography,
releases from these properties could impact the property.
In April 2015, ECS completed a soil and groundwater assessment k _0S Project 25395, report
dated May 15, 2015) to determine if the on -site and/or off -site RECs eve impacted the site.
Laboratory analysis of soil samples collected in the vicinity of the former cline UST and fuel
oil UST detected total petroleum hydrocarbons (TPH) at concentrate � tr, . exceed th State
Action Level of 10 parts per million (ppm).
On July 24, 2015, ECS was contracted to remove the 2,000 gallon heating oil UST. Following
receipt of the laboratory analytical data, a release of petroleum was detected beneath the UST.
Approximately 90.32 tons of petroleum -impacted soils were excavated and transported to
Earthtec Environmental Inc. in Bear Creek, North Carolina for disposal and treatment.
Laboratory analysis of two confirmation soil samples detected 1-methyl naphthalene and/or
naphthalene above the Soil -to -Groundwater Maximum Soil Contaminant Concentrations
(MSCCs). An Initial Abatement Report was completed on September 8, 2015. ECS
recommended that a Phase I Limited Site Assessment (LSA), Notice of Residual Petroleum
(NRP), and Public Notice be completed to obtain a Notice of No Further Action (NFA) for the
gasoline and heating oil UST releases.
1.1 UST Information
No records of the UST system(s) were discovered for the site; however, one 2,000-gallon heating
oil UST was discovered and removed from the site in July 2015, one gasoline UST of unknown
size was removed from the site at some time in the past, and a diesel UST of unknown size was
removed from the site at some time in the past.

used car dealer.
3.7 Property Owners and Occupants
The names and addresses of the property owners of the site and adjacent properties are included
in Table 1. A portion of a Guilford County GIS map with adjacent property locations is presented
as Figure 3.
4.0 SITE GEOLOGY AND HYDROGEOLOGY
According to the Geologic Mar North Carolina (1985), the subject property is situated in the
Milton Belt of the Piedmont F ,siographic Province. The soils encountered in this area are the
residual product of in-placE ^hemir-' weathering of rock presently underlying the site. In
general, shallow unconfined groundwater movement within the overlying soils is controlled
largely by topographic gradients. However, as the groundwater percolates downward to the
bedrock, it becomes controlled by the orientation of the rock fracture systems. Thus, the
direction of groundwater movement may D, ►,e consistent with the reflecting topography.
Recharge occurs primarily by infiltration E ig highe- ations and typically discharges into
streams or other surface water bodies. The elevation of e shallow water table is transient and
can vary with seasonal fluctuations in precipitation. Movement of groundwater under water
table conditions is generally from higher to lower elevations.. , such, shallow groundwater
would be expected to flow to the south-southwest beneath the site.
5.0 FIELD ACTIVITIES
5.1 Soil Sampling
On August 12, 2015, ECS observed the drilling of soil borings TW ,n the vicinity of the former
gasoline UST and TW-2 within the former fuel oil tank excavation (Figure 4). The soil borings
were drilled using a track -mounted Geoprobe® drill rig. The Geoprobe® is capable of driving
various forms of soil and groundwater sampling probes into the ground to depths equivalent to
auger refusal. The Geoprobe® subcontractor used for this project was 3D Environmental
Investigations, LLC (3D). The field activities were observed by an ECS professional. Prior to
initiating the first boring and between each subsequent boring, the Geoprobe® drill rig and
associated down -hole equipment were decontaminated with a high-pressure steam cleaner.
Soil samples were collected continuously from the ground surface to the termination depth of
the boring. The soil from the boring was screened for relative levels of volatile organic vapors
using the probe of a Thermo Model 2020 toxic vapor analyzer flame ionization detector (FID).
To screen the samples, the soil from the boring was placed in resealable plastic bags and
placed in a warm location for approximately ten minutes to allow the headspace in the bag to
equilibrate with the soil. The probe of the FID was then inserted into the bag and the reading
recorded. Soil samples from the 5-foot and 10-foot intervals of boring TW-1 (TW1-5 and TW1-
10) were submitted for chemical analysis. Because soil beneath the fuel oil UST was excavated
to the water table, no soil samples were collected from soil boring TW-2. Boring logs with FID
readings are included in Appendix C.

The sampler wearing a new pair of nitrile gloves for each sample placed the samples in
laboratory prepared containers, labeled them, and placed them into a cooler with ice to maintain
the samples at a temperature of 4°C. The samples were transported to Research and
Analytical Laboratories, Inc. (R&A) for chemical analysis. Soil samples TW1-5 and TW1-10
were analyzed for volatile organic compounds (VOCs) using EPA Method 8260/5035 and
volatile petroleum hydrocarbons (VPH) using the Massachusetts Department of Environmental
Protection (MADEP) Methods. A Chain -of -Custody (COC) Record was maintained during the
sample collection and transportation process and is included in Appendix D.
5.2 Monitoring Well Construction
Temporary monitoring wells TW-1 and TW-2 were installed in the soil borings (Figure 4). The
wells were constructed with 1-inch .D. Schedule 40 PVC flushed -threaded casing and screen.
The PVC screen and casing were lowered to the bottom of the borehole. A 10-foot length of
slotted well screen with macnined 0.010-inch slot widths and threaded bottom plug was
installed at the bottom of the well. A solid section of PVC casing was placed above the
screened interval and extended to just above the ground surface. The top of the casing was
fitted with an expandable lockable cap. The annular space around the well screen was filled
with a washed, fine filter sand to approximately 2 f ;et above the top of the screen. A minimum
2-foot thick seal of bentonite pellets waE :ed immediately above the sand pack. The
monitoring well construction diagrams can be round in Ar ndix E.
5.3 Groundwater Sampling
On August 13, 2015, monitoring wells TW-1 and TW-2 were sarr,, '4d. The depth of the static
water table was measured and is included on the boring logs. Prior to sampling, the wells were
developed/purged by removing at least three well volume . The alls were developed/purged to
remove sand, silt and other fine sediments which may have entered the well during construction
and to promote communication between the surrounding forme' - , and the sand pack
surrounding the well's screened interval. The wells were develop purged using a peristaltic
pump and a new section of polyethylene tubing. After the purging was completed, a
groundwater sample was collected from the well using the pump and transferred into sample
containers provided by the laboratory. After being filled, the sample containers were appropriately
labeled, placed into a cooler containing ice to maintain the samples at approximately 40C and
transported to Research and Analytical Laboratories, Inc. (R&A). The groundwater sample
collected from monitoring well TW-1 was analyzed for VOCs using EPA Method 6200B, VPH
using the MADEP Method, ethylene dibromide (EDB) using Standard Method 504.1, and lead.
The groundwater sample collected from monitoring well TW-2 was analyzed for VOCs using
EPA Method 6200B, SVOCs using EPA Method 625BNA, and VPH and EPH using the MADEP
Methods.

6.0 LABORATORY ANALYTICAL RESULTS
6.1 Soil Sample Analysis
Laboratory analysis of the soil sample TW1-5 detected several VOCs above the laboratory
reporting limits but not above their soil -to -groundwater Maximum Soil Contaminant
Concentration (MSCC). Naphthalene was detected at a concentration above its soil -to -
groundwater MSCC but not above its residential MSCC. Laboratory analysis of the soil sample
TW1-10 did not detect VOCs or VPH compounds above the laboratory reporting limits. The
sample results are summarized in Table 2. The laboratory data sheets are included in
Appendix D.
6.2 Groundwater Sample Analysis
Laboratory analysis of the gro, water sample collected from monitoring well TW-1 detected
several VOCs above the la' atory reporting limits but not above their North Carolina 2L
Groundwater Quality Stanc, i (NC21-GWQF). Tetrachloroethene (PCE) was detected above
its NC2LGWQS; however tht ,~ �tratiu, i does not exceed its Gross Contamination Level
(GCL). Laboratory analysis of we gre, 4water sample collected from monitoring well TW-2
detected several SVOCs above the Ir ,atury rep- rting limits but not above their NC2LGWQS.
Naphthalene, 1-methyl naphthalene and C9-C2_2 aromatics were detected above their
NC2LGWQS but not above their GCLs. A summary the groundwater laboratory analytical
results is summarized in Table 3. The laboratory data s► 3ts are included in Appendix D.
7.0 CONCLUSIONS
Based on the results of the LSA, ECS concludes the ijllr g,
• Laboratory analysis of the soil samples collected in the area of the gasoline and heating
oil USTs detected naphthalene and 1-methyl naphthalene at a concer,,ration above their
Soil -to -Groundwater Maximum Soil Contaminant Concentration (MSCC): however, the
concentration were not above the residential MSCC.
Laboratory analysis of the groundwater samples collected from monitoring well in the
vicinity of the former gasoline and heating oil USTs detected PCE, naphthalene, and 1-
methyl naphthalene, respectively above their NC2LGWQS; however the concentrations
do not exceed their GCLs. The property located on the adjoining property east of the
site was formerly a wholesale industrial laundry and drycleaning supplies business
(Sanborn fire insurance map information); and was later owned by Ashland Chemical.
There are documented releases on this property. This off -site property is currently
vacant but the location of a former solvent tank area was adjacent to the subject
property. Based on the assumed groundwater flow direction, to the south-southwest, it
is ECS's opinion that the PCE detected in TW-1 is from an off -site documented release.
The concentration of PCE in the groundwater is below the North Carolina Division of
Waste Management's Residential Vapor Intrusion Screening Level.
No water supply wells were observed within 1,500 feet of the source area. The property
is currently supplied with municipal water. Water supply well questionnaires were

mailed to 11 property owners within 500 feet of the subject property. No water supply
wells were reported by the survey.
8.0 RECOMMENDATIONS
ECS recommends that a copy of this report be submitted for review to the Guilford County
Department of Environmental Health (GCDEH). The GCDEH is the implementing agency of the
NCDENR in Guilford County. Based on the soil and groundwater analytical results and the
absence of water supply wells within 1,000 feet of the release, ECS recommends that a Notice
of No Further Action (NFA) be issued for the releases pending submittal and receipt of a Notice
of Residual Petroleum (NRP) restricting groundwater use for the site.
