1.0 PROJECT INFORMATION
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. There was is no evidence that hazardous chemicals have been
utilized at the site by ATCO during flexible ductwork production.
The subject site is currently occupied by two buildings which were recently used to manufacture
flexible ductwork and as a warehouse. A portion of the main building is currently used as an
used automobile sales business. An old boiler is located in a room on the southeast side of the
main building. The building boiler is no longer in use. It appears that the boiler last operated on
natural gas; however, there is a copper line running from the boiler to the outside of the building
indicating the use of fuel oil.
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 second
UST was believed to be located near the northwest corner of the warehouse and a third UST
believed to be a heating oil UST is located south of the warehouse, near the former boiler room.
The site is located in a light industrial/commercial area of Greensboro. The site is bound on the
north by the Norfolk Southern railway property, on the east by light industrial/commercial
properties, on the south by a light industrial/commercial building and Patterson Street and on
the west by South Holden Road.
Two properties (former Chemical & Solvent, Inc. and former Ashland Chemical) that previously
contained chemical manufacturing/storage facilities are located on adjoining properties east of
the site. Based on proximity, the releases form these properties are considered RECs of the site.
Releases are identified at the Norfolk Southern railway property north of the site. Based on
proximity and groundwater flow direction inferred from the surface topography, releases at this
property could impact the property.
ECS was contracted by Mr. Eddie Krusch to conduct a soil and groundwater assessment at the
site to determine if the identified RECs could have impacted the site. Project information is
based on a conversation between Mr. Krusch and Mr. Randy Cavallier of ECS, the previous
Phase I ESA, and a recent site visit.

2.0 FIELD ACTIVITIES
2.1 Soil Assessment
On April 28, 2015, nine soil borings were drilled at the site to assess whether the suspect USTs
had had a release. Soil borings UST-1 A, UST-1 B and UST-1 C were drilled in the vicinity of the
concrete patched area on the northern portion of the site (suspected former diesel UST location).
Soil borings UST-2A, UST-213, UST-2C, and UST-2D were drilled in the vicinity of a second
concrete patched area (suspected gasoline UST location) and soil borings UST-3A and UST-313
were drilled in the vicinity of the suspected fuel oil UST. The approximate locations of the soil
borings are shown on Figure 3 and Figure 3A.
ECS proposed drilling the borings to a depth of 15 feet below the ground surface (bgs); however,
groundwater was detected at a depth of approximately 11 to 12 feet bgs, so the borings were
terminated at 10 feet bgs.
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® down -hole equipment was decontaminated with a high-pressure steam cleaner.
Soil samples were collected continuously from the ground surface to the termination depth of
each boring. The soil from each boring was screened for relative levels of volatile organic
vapors using the probe of a Thermo Model 2020 flame ionization detector (FID). To screen the
samples, the soil from the borings 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. The soil
sample from each boring with the highest reading on the FID was submitted for chemical
analysis. Because the purpose of the assessment was to determine presence or absence of
contamination, one sample from the gasoline UST area and one sample from the heating oil
UST area were not submitted for analysis, since field conditions indicated the presence of a
release.
The sampler, wearing a new pair of nitrile gloves, placed the samples in laboratory prepared
containers. Each container was labeled and placed in a cooler containing ice to maintain the
samples at approximately 4° Celsius. The samples were transported to Research and
Analytical Laboratories (R&A) in Kernersville, North Carolina to be analyzed for diesel range
and gasoline range total petroleum hydrocarbons (TPH) EPA Methods 8015/3550 and
8015/5035, respectively. Chain of Custody Records were maintained and included in Appendix
A.
2.2 Groundwater Assessment
To determine if the groundwater beneath the site has been impacted from the USTs and off -site
sources, four groundwater samples (GW-1 through GW-4) were collected at the site (Figure 4).
The groundwater samples were collected by pushing a groundwater -sampling probe to the desired

depth (generally five feet below the water table) and pulling back on the probe, exposing the
sampling screen. A piece of dedicated polyethylene tubing was inserted down the probe to the
depth of the screen. The tubing was connected to a peristaltic pump that was used to collect the
sample. The groundwater samples were submitted to R&A and analyzed for volatile organic
compounds (VOCs) and semi -volatile organic compounds (SVOCs) using Standard Method
6200B and EPA Method 625BNA, respectively. Upon completion of groundwater sampling
activities, the temporary monitoring points were properly abandoned. A Chain of Custody
Record was maintained and is included in Appendix A.
3.0 LABORATORY ANALYSIS
3.1 Soil Sample Results
Laboratory analysis of soil samples UST-2A, UST-213, and UST-313 detected gasoline and diesel
range TPH above the North Carolina Department of Environment and Natural Resources
(NCDENR), State Action Level of 10 parts per million (ppm). The laboratory analytical results
are summarized in Table 1. The laboratory data sheets are included in Appendix A.
3.2 Groundwater Sample Analysis
Laboratory analysis of the samples GW-1, GW-2 and GW-4 detected 1,2-dichloropropane at
concentrations that exceed the North Carolina 2L Groundwater Quality Standard (NC2LGWQS).
Laboratory analysis of the samples GW-3 and GW-4 detected tetrachloroethene (PCE) at
concentrations that exceed the NC2LGWQS. Ten additional VOCs were detected in sample
GW-4 at concentrations that exceed their respective NC2LGWQS. The laboratory analytical
results are summarized in Table 2. The laboratory data sheets are included in Appendix A.
4.0 CONCLUSIONS
Based on the results of the limited soil and groundwater assessment, it is ECS's opinion that
soil in the vicinity of the former gasoline UST and the heating oil UST have been impacted from
releases or spills of petroleum products associated with the USTs. It is our opinion that the
hydrocarbons detected in the groundwater are associated with releases from the off -site
sources.
5.0 RECOMMENDATIONS
Based on the laboratory analytical results of the samples collected during the recent soil and
groundwater assessment, ECS understands that a reporting obligation exists. ECS
recommended that a copy of the report be provided to the property owner and that they consult
legal counsel regarding their reporting obligation.
