1. PROJECT INFORMATION

The site is approximately 12.076 acres of land developed with Hendrick Durham Auto Mall and
associated gravel parking lot located at 409 South Roxboro Street and 464 East Pettigrew
Street in Durham, Durham County, North Carolina, (Figure 1). ECS is currently conducting a
Phase I Environmental Site Assessment (ESA) for the site (ECS Project No. 06:21380). ECS
identified the following recognized environmental conditions (RECs) with respect to the subject site:

• The documented releases associated with the former use of the site as a hosiery mill
and a printing facility;

• The current use of the site as an automotive dealership and maintenance facility; and

• The historical use of surrounding properties as auto repair facilities, dry cleaning
facilities, and industrial uses.

The Phase I ESA has identified the following Controlled Recognized Environmental Conditions
(CRECs):

• The documented releases associated with the subject site.

Based on a potential real estate transaction, ECS was contracted to conduct a Phase II
Environmental Site Assessment of the site to determine whether the RECs have impacted the
site. Project information is based on correspondence between Mr. Shane Seagle with Durham
Partnership Group and Mr. Brian Smith with ECS, and the previously cited Phase I ESA/other
document

2. SCOPE OF SERVICES

The Phase II ESA consisted of collecting soil and groundwater samples using a Geoprobe® drill
rig. The subcontractor used for this project was 3D Environmental Investigations, LLC.

Field activities were conducted on February 11, 2014 and observed by an ECS professional.
Prior to commencing with field activities, ECS contacted Public Utility Locator - Utility Locate NC
One-Call and Private Utility locator Superior Locate 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
with field activities, ECS, the subcontractors and applicable site personnel reviewed the site-
specific HASP.

The Geoprobe® consists of a hydraulic jack mounted on an all-terrain vehicle (ATV). The
Geoprobe® is capable of driving various forms of groundwater, soil, and soil-gas sampling
probes into the ground to depths equivalent of auger refusal.

Six soil borings, SB-1 through SB-6, were advanced at site during the Geoprobe. Locations of
soil borings are presented in Figure 2. Depth of each soil boring was ten feet bgs or to a depth
equivalent to auger refusal. Each soil boring was advanced by hydraulically driving a five-foot
long, 1.5-inch soil sampling probe into the soil. Prior to advancing each boring, the down hole
equipment and Geoprobe® drill rig were decontaminated utilizing a high pressure steam cleaner
that utilized municipal water. The down hole equipment and drill rig were decontaminated to
prevent cross-contamination between boring locations. The soil sampling probe was lined with a
disposable clear plastic tube, which was replaced with each five-foot interval. After the probe
was driven, the clear plastic tube filled with soil was removed from the probe. The clear plastic
tube was then cut open to remove the soil. 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. Boring logs, which include descriptions of the soils encountered and field
screening results, were prepared for each boring and are included in the Appendix. Upon
completion, each boring was properly abandoned.

Each soil sample collected in the field was transferred into a new, clean resealable bag (half full),
and the bag placed in a warm location. Approximately ten minutes after the time of collection, the
bag was opened slightly and the probe of a miniRAE 2000 PID was inserted, and the bag
immediately resealed using finger pressure. The meter of the PID was monitored and the reading
recorded. The recorded PID responses are presented on the boring logs included in the Appendix.

One temporary monitoring well, SB-3/GW-1, was installed in boring SB-3 drilled as discussed
above. Location of the well is presented in Figure 2. The temporary well was constructed with one-
inch inner diameter (I.D.). Schedule 40 PVC flush-threaded casing and screen. The PVC screen
and casing was lowered into the open borehole. A ten-foot length of slotted well screen with
machined 0.010-inch slot widths and a threaded bottom plug were installed at the bottom of the
well. The screen was installed to a depth such that the screened interval intersected the estimated
groundwater surface. A solid section of PVC casing was placed above the screened interval and
extended to a point just above the ground surface. The annular space around the well was filled
with washed and graded medium sand to approximately two feet above the top of the screen. A
boring log was prepared for the temporary monitoring well, which is included in the Appendix.

The groundwater sample was collected using a peristaltic pump with a new section of plastic
tubing lowered into the groundwater. The groundwater was pumped directly into the laboratory
prepared containers. In addition, ECS collected water quality parameters during the sampling
using a YSI 556 Water Quality Meter. The results of the water quality parameters are
summarized in Table 1.

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, Inc. in Charlotte, North Carolina and
NC certification number 402.

The soil samples were submitted for chemical analysis for volatile organic compounds (VOCs)
using EPA Method 8260B, and for semi-volatile organic compounds (SVOCs) using EPA
8270D.

The groundwater samples were submitted for chemical analysis for VOCs using Standard
Method 6200B plus IPE, MTBE, and ethylene dibromide (EBD) using EPA Method 504.1, and
SVOCs using EPA Method 625BNA plus ten tentatively identified compounds (TIC). ECS
maintained proper chain-of-custody (COC) procedures throughout the sample collection and
transportation process. Copies of the COCs are appended to the laboratory test reports.

3. RESULTS

• Laboratory analysis of soil samples SB-2 through SB-5 did not detect targeted analytes
VOCs and SVOCs above laboratory detection limits;

• Laboratory analysis of soil sample SB-1 detected methyl butyl ketone (2-hexanone)
above laboratory detection limits; however, the concentration does not exceed its
respective Soil-to-Groundwater Maximum Soil Contaminant Concentrations (MSCC);

• Laboratory analysis of soil sample SB-1 detected benzene at a concentration that
exceeds its Soil-to-Groundwater MSCCs. However, the concentration does not exceed
its Industrial/Commercial Soil Cleanup Levels (ISCLs) ;

• Laboratory analysis of soil sample SB-6 detected the polycyclic aromatic hydrocarbons
(PAC), acenaphthylene, anthracene, benzo(g, h, i)perylene, benzo(k)fluranthene,
chrysene, dibenzofuran, fluranthene, fluorene, 2-methylnaphthalene, phenanthrene, and
pyrene above laboratory detection limits; however, the concentrations do not exceed
their respective MSCCs;

• Laboratory analysis of soil sample SB-6 detected benzo(a)anthracene, benzo(a)pyrene,
benzo(b)floranthene, dibenzo(a,h)anthracene, indeno(1,2,3-cd)pyrene, and naphthalene
at concentrations that exceed their respective MSCCs. The concentrations of
benzo(a)anthracene, benzo(a)pyrene, benzo(b)floranthene, dibenzo(a,h)anthracene,
and indeno(1,2,3-cd)pyrene exceed their respective ISCLs;

• Laboratory analysis of groundwater sample SB-3/GW-1 did not detect target VOCs or
SVOCs above laboratory reporting limits;

• A summary of the laboratory analytical results is included in Tables 2 and 3;

• The laboratory test results with COCs are included in the Appendix.

4. CONCLUSIONS

Based on the results of the Phase II ESA, ECS concludes the following:

• On February 11, 2014, ECS observed and documented the advancement of six soil
borings and one temporary monitoring well at the site;

• Groundwater was encountered at an approximate depth of 12.15 feet bgs;

• Drilling refusal was encountered at an approximate depth of 7 feet bgs, except for SB-3
where drilling refusal was encountered at a depth of 16 feet bgs;

• Six soil samples were submitted to a certified laboratory for chemical analysis for VOCs
using EPA Method 8260B and for SVOCs using EPA 8270D;

• One groundwater sample was submitted to a certified laboratory for chemical analysis
for VOCs using Standard Method 6200B plus IPE, MTBE, EBD using EPA Method
504.1, and SVOCs plus 10 TICs using EPA Method 625BNA;

• Laboratory analysis of soil samples SB-2 through SB-5 did not detect targeted analytes
VOCs and SVOCs above laboratory detection limits;

• Laboratory analysis of soil sample SB-1 detected methyl butyl ketone (2-hexanone)
above laboratory detection limits; however, the concentration does not exceed its
respective Soil-to-Groundwater Maximum Soil Contaminant Concentrations (MSCC);

• Laboratory analysis of soil sample SB-1 detected benzene at a concentration that
exceeds its Soil-to-Groundwater MSCCs. However, the concentration does not exceed
its Industrial/Commercial Soil Cleanup Levels (ISCLs);

• Laboratory analysis of soil sample SB-6 detected the polycyclic aromatic hydrocarbons
(PAC), acenaphthylene, anthracene, benzo(g, h, i)perylene, benzo(k)fluranthene,
chrysene, dibenzofuran, fluranthene, fluorene, 2-methylnaphthalene, phenanthrene, and
pyrene above laboratory detection limits; however, the concentrations do not exceed
their respective MSCCs;

• Laboratory analysis of soil sample SB-6 detected benzo(a)anthracene, benzo(a)pyrene,
benzo(b)floranthene, dibenzo(a,h)anthracene, indeno(1,2,3-cd)pyrene, and naphthalene
at concentrations that exceed their respective MSCCs. The concentrations of
benzo(a)anthracene, benzo(a)pyrene, benzo(b)floranthene, dibenzo(a,h)anthracene,
and indeno(1,2,3-cd)pyrene exceed their respective ISCLs;

• The suspected source of this impact could be the documented releases associated with
the site;

• The extent of impact to the site has not been fully delineated. Additional assessment
would be necessary to fully delineate the extent of impact to the site.

5. RECOMMENDATIONS

Based on the results of the Phase II ESA, ECS recommends the following:

• ECS recommends that the current property owner be notified and that they submit a
copy of the report to the NCDENR for their review; and

• The NCDENR will likely require that the extent of impact be delineated and subsequently
remediate to applicable cleanup levels.
