1. PROJECT INFORMATION
The site consists of twelve parcels located between Camden Road, South Tryon Street, and
West Park Avenue in Charlotte, Mecklenburg County, North Carolina, Figure 1. In conjunction
with this assessment, ECS conducted a Phase I Environmental Site Assessment (ESA) (ECS
Project No. 08-10875-A, dated August 25, 2015) for the site. ECS identified the following
recognized environmental conditions (RECs) with respect to the subject site.
The presence of a monitoring well associated with the former Clawson Radiator or
Brownfields listing located on the site.
The auto repair facilities, potential dry cleaning facilities, chemical laboratories, photo
finishing facilities identified during the historical information review as being formerly located
on the site.
Multiple facilities identified in the EDR report in the vicinity of the site. Based on the
proximity to the site and/or the direction of groundwater flow inferred from surface
topography, ECS considers the following facilities and/or properties discussed in the
Environmental Records Review section to be RECs of the site: Kee Auto Top
Manufacturing Co. (1538 South Tryon Street), Beaty Bros Service Station (1541 South
Tryon Street), Light Rail (1511 Camden Road), Miller Service, (100 East Park Avenue, H H
Service Station (1600 Camden Road), 1600 Camden Road (1600 Camden Road), Fowler
Building (1447 South Tryon Street), Charlotte Coal Gas Plant No. 2 (South Boulevard),
BCD Development Property, LLC (1611 South Tryon Street), and Delores Sheets
Residence (1612 South Tryon Street).
Several auto repair facilities, filling stations, photo finishing facilities, manufacturers, sheet
metal shops, and other commercial and/or retail businesses identified during the historical
information review as being currently and/or historically located on surrounding properties.
Based on a potential real estate transaction, ECS was contracted to conduct an assessment of
the site. Project information is based on correspondence between Mr. Jason Frost with Cousins
Properties Incorporated and Mr. Brian Olin with ECS and the previously cited Phase I ESA (not
completed at the time the field work was conducted).
2. SCOPE OF SERVICES
The soil and groundwater assessment consisted of collecting four groundwater and four soil
samples on August 22, 2015 using a drill rig equipped to drill with hollow-stem augers. At the
request of the client, the environmental sampling was conducted in conjunction with and using
the driller used to for the geotechnical investigation. The proposed geotechnical boring locations
were modified by adding several additional borings to collect environmental samples. The
subcontractor used for this project was Pressley Drilling. Prior to commencing with field
activities, ECS contacted North Carolina One-Call to locate/mark public utilities at the site.
Required separation distances between subsurface activities and marked utilities (typically 30-
inches) were maintained during the field activities.
As part of this assessment, ECS prepared a site-specific health and safety plan (HASP) for the
site. The HASP documented the known or suspected hazards, applicable personal protective
equipment (PPE) of site personnel, and emergency response procedures. Prior to commencing

Charlotte, North Carolina
ECS Project No. 08-10875-B

with field activities, ECS and its subcontractors and applicable site personnel reviewed the site-
specific HASP.
The soil borings were drilled using a drill rig equipped to drill using hollow-stem augers. Drilling
with hollow-stem augers involves rotating a continuous stem of hollow-stem augers into the
ground. As drilling advances, the soil cuttings are removed by the rotating auger. At each sample
location, the augers are disconnected from the drill rig providing access to the interior of the augers
to facilitate soil sampling. Representative soil samples were collected at approximate five-foot
intervals using a split-spoon sampler. ECS visually classified the soils collected from each boring
and screened the soil samples for relative levels of volatile organic vapors using a field
screening instrument a (Rae Systems Mini Rae 3000 Photo-ionization detector (PID)). Evidence
of contamination or elevated PID readings were not detected, so soil samples were collected
from above the soil-groundwater interface. Upon completion, each boring was properly
abandoned.
When groundwater was encountered while drilling the geotechnical borings, a sample of water was
collected by lowering a disposable bailer through the augers. A groundwater sample was from
geotechnical borings B-1, B-2, and S-1 (This method was used as opposed to temporary
monitoring wells as proposed to accommodate the clients request to conduct the environmental
sampling in conjunction with the geotechnical drilling.) Immediately after collection, the
groundwater sample was transferred into sample containers provided by the laboratory. Because
well were not installed, accurate groundwater elevations could not be obtained to allow for
determination of groundwater flow direction.
The existing monitoring well (MW -1) was purged by removing three well volumes. After the purging
was completed, a groundwater sample was collected from the well. Purging and sampling was
accomplished using a new disposable polypropylene bailer. Immediately after collection, the
groundwater sample was transferred into sample containers provided by the laboratory.
The soil and groundwater samples were placed into laboratory prepared containers. The sample
containers were labeled with ECS project number, sample identification, sample date and time,
and requested analytical analysis. The containers were placed into protective packaging
material and placed into a cooler with ice to maintain the samples at approximately 4 Celsius
(C). The samples were submitted to (Prism Laboratories located in Charlotte, North Carolina
(North Carolina Certification # 402) for chemical analysis for volatile organic compounds (VOCs)
and semi-volatile organic compounds (SVOCs) using EPA Methods 8260 and 8270,
respectively. ECS maintained proper chain-of-custody (COC) procedures throughout the sample
collection and transportation process. Copies of the COCs are included in the Appendix.
3. RESULTS
Laboratory analysis of soil samples S-1, S-2, S-3, and B-5 did not detect targeted analytes
(VOCs and SVOCs) above laboratory detection limits, except for acetone, a common laboratory
contaminant, in S-2. The concentration does not exceed the North Carolina Maximum Soil
Contaminant Concentrations (MSCCs) or the North Carolina Soil Remediation Goals (SRGs).
Laboratory analysis of groundwater sample MW -1 did not detect targeted analytes (VOCs and
SVOCs) above laboratory detection limits.

Laboratory analysis of groundwater samples B-1GW, B-2GW, and S-1GW detected several
chlorinated VOCs above laboratory detection limits and North Carolina 2L Groundwater Quality
Standards (NC2LGWQS). Trichloroethylene was detected above the Division of Waste
Management’s (DWM) vapor screening level in the groundwater sample collected from boring
B-2 located on the west side of the site.
A summary of the groundwater laboratory analytical results is included in Table 1. The
laboratory data sheets are included in the Appendix.
4. CONCLUSIONS
Based on the results of the soil and groundwater assessment, ECS concludes the following:
Evidence of a release (petroleum/chemical odors, staining, sheens, elevated readings on
the PID) was not detected in the soil where sampled during assessment activities.
Groundwater was encountered at an approximate depth of 15 feet bgs.
Laboratory analysis of soil samples did not detect targeted analytes at concentrations that
exceed the applicable North Carolina MSCCs or SRGs.
Laboratory analysis of groundwater samples B-1 GW, B-2 GW, and S-1 GW detected
targeted analytes at concentrations that exceed the NC2LGWQS and the DWM’s vapor
screening level in B-2 GW.
5. RECOMMENDATIONS
Based on the results of the assessment, ECS recommends the following:
Evidence of impacts to the site from historical on-site activities was not identified during the
assessment based on the soil sampling or the existing on-site monitoring well.
Evidence of groundwater impacts from off-site sources was identified during the
assessment, as the compounds detected were consistent with the off-site RECs, were
detected in the perimeter groundwater samples near the off-site RECs, and were not
detected in the soil samples or monitoring well located in the historical location of onsite
operations.
If dewatering is required during site development, management of impacted groundwater
will be necessary.

Soil gas samples should be collected to assess the possibility of vapor intrusion into on-site
buildings or proposed buildings.
ECS recommends that the current property owner be notified and that they submit a copy of
the report to the North Carolina Department of Environment and Natural Resources
(NCDENR) for their review.
6. QUALIFICATIONS OF REPORT
The activities and evaluative approaches used in this assessment are generally consistent with
those normally employed in soil and groundwater assessment projects of this type. As the soil
and groundwater sampling was conducted in conjunction with the geotechnical drilling and
groundwater samples were collected though the augers instead of via temporary wells or a
designated groundwater sampling probe, it is possible that cross contamination could have
occurred. Our evaluation of site conditions has been based on our understanding of the site
project information and the data obtained during our field activities. This report was prepared for
the express use of Cousins Properties Incorporated. Use of this report by other individuals or
companies implies their acceptance of the General Conditions of Service of the original
contract.

Dear Alexandra Perillo:
The North Carolina Natural Heritage Program (NCNHP) appreciates the opportunity to provide information
about natural heritage resources for the project referenced above.
A query of the NCNHP database, based on the project area mapped with your request, indicates that there are
no records for rare species, important natural communities, natural areas, or conservation/managed areas
within the proposed project boundary. Please note that although there may be no documentation of natural
heritage elements within the project boundary, it does not imply or confirm their absence; the area may not have
been surveyed. The results of this query should not be substituted for field surveys where suitable habitat exists.
In the event that rare species are found within the project area, please contact the NCNHP so that we may
update our records.
The attached ‘Potential Occurrences’ table summarizes rare species and natural communities that have been
documented within a one-mile radius of the property boundary. The proximity of these records suggests that
these natural heritage elements may potentially be present in the project area if suitable habitat exists and is
included for reference. Tables of natural areas and conservation/managed area within a one-mile radius of the
project area, if any, are also included in this report.
Please note that natural heritage element data are maintained for the purposes of conservation planning, project
review, and scientific research, and are not intended for use as the primary criteria for regulatory decisions.
Information provided by the NCNHP database may not be published without prior written notification to the
NCNHP, and the NCNHP must be credited as an information source in these publications. Maps of NCNHP
data may not be redistributed without permission.
The NC Natural Heritage Program may follow this letter with additional correspondence if a Dedicated Nature
Preserve (DNP), Registered Heritage Area (RHA), Clean Water Management Trust Fund (CWMTF) easement,
or Federally-listed species are documented near the project area.
If you have questions regarding the information provided in this letter or need additional assistance, please
