1.0 INTRODUCTION

ATC Associates of North Carolina, P.C. (ATC) is pleased to submit this Phase II Environmental Site
Assessment (Phase II ESA) to Cousins BD Investments L.P. documenting environmental assessment
activities at the Erwin Square property located at 2200 West Main Street in Durham, North Carolina.
A Site Vicinity Map is included as Figure 1. The scope of the Phase II ESA included a regulatory
file review, groundwater sampling, sub-slab soil gas sampling, and indoor air sampling. The results
of the Phase II ESA were evaluated in general accordance with the applicable North Carolina
Department of Environment and Natural Resources (NCDENR) regulations.

The property consists of approximately 7.519-acres of land improved with a ten-story office building
flanked to the north and west by two-story retail/office buildings and an attached four-story parking
garage. According to tax appraisal information obtained from the Durham County Geographic
Information System (GIS), the property is identified as Parcel Identification Number 0822-17-11-
7823 and is zoned for commercial usage. The legal description for the property is TR 1 ERWIN
SQUARE-PB 138-65. A Site Map is included as Figure 2. The surrounding area land use is primarily
characterized as vacant, office, and residential land. Specifically, the site is bordered to the north by an
apartment complex and an office building, to the east and west by vacant land, and to the south by
West Main Street followed by NC Highway 147.

2.0 SITE HISTORY AND NCDENR FILE REVIEW RESULTS

On September 26, 2011, ATC completed a Phase I Environmental Site Assessment (Phase I ESA) of
the property. Based on the findings of the ESA, the site property is part of a former Burlington
Industries Textile Mill with documented groundwater impacts. As part of the Phase II ESA scope of
work, ATC reviewed regulatory files maintained by NCDENR for the site. According to NCDENR
files, the site property and adjacent properties to the north and east were occupied by a textile mill
from the early 1900’s until the 1980’s. Environmental investigations were initiated in 1986 shortly
following shut-down of mill operations. Possible release sources identified during the initial
investigations included gasoline and varsol underground storage tanks (USTs), a waste oil UST, No.
5 and No. 2 fuel oil USTs, a waste oil pit, gasoline aboveground storage tanks (ASTs), a former
machine shop, floor drains and sumps, and areas of stained soil. Sampling in each of these areas
revealed impacted soil in various locations as well as generally low concentrations of volatile organic
compounds (VOCs) in groundwater. The primary constituent of concern in groundwater was
determined to be 1,1-dichloroethylene (1,1-DCE). Approximately 2,756 cubic yards of impacted soil
were excavated during demolition of the former mill between 1987 and 1989. The existing
retail/office building was then constructed in the southwestern portion of the former mill area in 1990.

In February 2000, Law Engineering and Environmental Services, Inc. (Law) prepared a Corrective
Action Plan (CAP) recommending monitoring natural attenuation of impacted groundwater. The
CAP concluded that the majority of source area impacted soil had been removed during the prior
excavation activities, and isolated areas of remaining impacted soil were not deemed a significant
risk. Periodic groundwater sampling events to monitor natural attenuation were recommended to
address residual 1,1-DCE impacts to groundwater. The CAP was approved by NCDENR in
December 2000. Groundwater sampling events were then completed to monitor natural attenuation
between 2001 and 2005. On April 18, 2007, the property owner sent a letter to NCDENR indicating
that Burlington Mills claimed they were no longer responsible for monitoring the wells and
requesting NCDENR’s assistance in enforcing the groundwater sampling obligations detailed in the
CAP. ATC did not identify a response to this request in NCDENR’s files. However, the remaining
impacts are currently regulated under the Inactive Hazardous Sites Branch (IHSB) of NCDENR. The

IHSB prioritizes sites and only directs work at higher risk sites. It appears that the site does not
currently rank high enough to require work and, as such, the IHSB has not requested additional
sampling.

In April 2011, Mid-Atlantic Associates Inc. performed a groundwater sampling event for selected
existing monitoring wells. Based on the data reviewed by ATC, this sampling appears to be the most
recent sampling event conducted on the site property. It should be noted that properties east and
north of the site, which were also part of the former mill, have entered the North Carolina
Brownfields Program, which is a voluntary program intended to provide liability protection to future
property owners. Additional sampling may have been conducted at these properties under the
Brownfields Program. However, these files were not the focus of ATC’s file review since they are
not associated with the site property.

3.0 PHYSICAL SETTINGS

3.1 Topography

ATC reviewed the USGS 7.5-Minute Series Topographic Map for the Northwest Durham, North
Carolina Quadrangle, dated 1999. According to the topographic map, the site property is situated
approximately 410 feet above mean sea level. The property slopes gently towards the northeast.
Run-off water infiltrates into areas of exposed soil or sheet flows to drainage ditches located through
the property.

3.2 Geology

According to the Geologic Map of North Carolina, 1985, the property lies within the Carolina Slate
Belt of the Piedmont Physiographic Province. More specifically, the property is underlain by
sedimentary rock of the Chatham Group with consists of conglomerates, mudstone, and sandstone
from the Triassic Period.

According to the U.S. Department of Agriculture (USDA) Soil Conservation Service (SCA) data, the
property is underlain by Urban Land. Urban Land has been cut, filled, graded, or otherwise changed
to the extent that the original soil characteristics have been altered or destroyed.

3.3 Hydrogeology

During groundwater sampling activities conducted on January 27, 2012, ATC gauged the depth to
water in monitoring wells MW-1, MW-2, MW-3, MW-4, MW-5, MW-6, and MW-7. The depths to
groundwater ranged from 9.61 to 15.32 feet below ground surface (bgs). Based on groundwater
elevation data, groundwater flow is locally variable, but the overall flow direction is east-northeast
across the site. Local variations in the groundwater flow direction were also reported during
historical sampling events and are characteristic of the low permeability Triassic Basin sediments
underlying the site. Monitoring well construction details are included in Table 1. Groundwater
elevation data is included in Table 2. A groundwater elevation contour map is included as Figure 3.

4.0 SUBSURFACE INVESTIGATION

4.1 Groundwater Sampling

On January 27, 2012, ATC mobilized to the site to conduct groundwater sampling activities. Prior to
well sampling, ATC purged three well volumes from each well. Following purging, ATC collected
Phase II Environmental Site Assessment Erwin Square
ATC Project Number 45.26881.1101 2200 West Main Street
Cousins BD Investments L.P. Durham, North Carolina
Cousins BD Investments L.P. 3 ATC Associates of North Carolina, P.C.
groundwater samples from monitoring wells MW-1, MW-2, MW-3, MW-4, MW-5, MW-6, and MW-
7. ATC attempted to collect a sample from monitoring well MW-15 but was unable access the well.
Groundwater samples were collected using disposable polyethylene bailers. Purge water accumulated
from the monitoring wells during sampling activities was placed in a 55-gallon drum that is currently
stored on the property. Following the retrieval of the drum by a certified waste handler, ATC will
submit the waste manifest to the Client.

The collected samples were placed in certified-clean, properly preserved containers appropriate for
the analysis of volatile organic compounds (VOCs) by EPA Method 8260B; stored in a cooler
containing ice for preservation; and submitted to Accutest Laboratories under standard chain-of-
custody procedures.

The laboratory analytical results indicated detectable concentrations of 1,1-DCE, 1,1-dichloroethane
(1,1-DCA), and trichlorofluoromethane. The detected concentrations were compared to three
different action levels, Title 15A NCAC 2L .0202 Groundwater Standards (2L Standards), Inactive
Hazardous Sites Branch (IHSB) Vapor Intrusion Screening Levels (VISLs) for residential
groundwater, and IHSB VISLs for industrial/commercial groundwater. 2L Standards are the remedial
goals that would need to be met in order for NCDENR to issue a no further action (NFA) letter for the
release incident. Exceedences of 2L Standards were identified for 1,1-DCE and 1,1-DCA. The IHSB
VISLs are the levels considered protective of building occupants for the vapor intrusion pathway.
Exceedences of IHSB VISLs for residential groundwater were identified for 1,1-DCE and
trichlorofluoromethane. Exceedences of IHSB VISLs for industrial/commercial groundwater were
identified for 1,1-DCE. Similar to prior sampling events, the primary constituent of concern for the
site appears to be 1,1-DCE. Concentrations of 1,1-DCE detected in January 2012 were higher than
concentrations detected during the prior sampling in April 2011, but generally within the range of
concentrations detected historically.

Groundwater laboratory analytical data is summarized in Table 3. A figure depicting chemicals of
concern in groundwater is included as Figure 4. A 1,1-DCE concentration versus time graph for
specific monitoring wells is included as Figure 5. The laboratory analytical report and chain of
custody documentation for the groundwater samples are provided in Appendix A.

4.2 Sub-Slab Soil Gas Sampling

Prior to initiation of the sub-slab soil gas sampling, the North Carolina One Call Service was
contacted to mark subsurface utilities at the site. On January 17, 2012, sub-slab soil gas monitoring
points SGMP-1 through SGMP-4 were installed at the locations shown on the attached Figure 6.
SGMP-1 was located in Wing B in the southernmost stairwell of the wing beneath the staircase.
SGMP-2 was located in the Main Building in the service hall whose entrance is located on the
northeast portion of the building. The boring was placed at the foot of stairs. SGMP-3 was located in
Wing B in the service hall whose entrance is located on the north portion of the wing. The boring
was placed at the foot of the stairs. Finally, SGMP-4 was located in Wing A in a public use stairwell.
The stairwell’s entrance is located on the north portion of wing in the bottom level of the parking
garage. The boring was placed at the foot and to the east of the stairwell.

At each sample location, a hammer drill was used to drill through the concrete floor slab inside the
building. The floor slab thickness in each location is approximately 5 to 6 inches. A piece of ¼-inch
Teflon tubing was installed at the base of the boring and connected to the surface. Beeswax was used
to seal the annular space to the ground surface.

Sampling of the sub-slab soil gas monitoring points was conducted shortly following installation.
Helium gas was used as a tracer during soil gas sampling activities for sample validation. A 5-gallon
bucket was placed over the sampling point to form a temporary shroud. Helium gas was then injected
into a fitting in the bucket. A field helium meter was used to periodically measure helium
concentrations within the shroud throughout the sampling process. Two three-way valves and a 60-
milliliter syringe were then connected to the sampling point tubing and used to purge approximately
three volumes from the sampling point. Following purging, the valves and syringe were used to
collect a vapor sample in a tedlar bag. Purging and sampling were conducted at a maximum flow rate
of 200 mL/minute. A field helium meter was used to measure the concentration of helium gas in the
sample. The helium concentrations in the shroud versus the sample were then compared to evaluate
for the presence of leaks. The results of the tracer gas testing indicated no significant leaks. Upon
completion of leak testing, a sample was collected in a 400 mL stainless steel mini-Summa canister
by connecting the canister to the Teflon tubing. The samples were packaged and shipped to H&P
Mobile Geochemistry, Inc. for analysis of VOCs by EPA Method TO-15.

The results of the laboratory analyses indicated detectable concentrations of benzene, toluene,
ethylbenzene, styrene, tetrachloroethylene, and trichlorofluoromethane in soil gas. Note that 1,1-
DCE was included in the soil gas analyses but was not detected. Constituent concentrations were
compared to the IHSB VISLs for residential and industrial/commercial soil gas. The results of this
comparison indicated benzene concentrations above IHSB VISLs for residential and
industrial/commercial soil gas in location SGMP-2. Note that benzene was not detected in
groundwater samples collected at the site, but it is possible that some isolated areas of benzene
impacts may be present in the subsurface soil or groundwater due to historical petroleum storage on-
site. Sub-slab soil gas analytical data is summarized in Table 4. The laboratory analytical report for
the sub-slab soil gas samples is included in Appendix B. A figure depicting chemicals of concern in
soil gas is included as Figure 7.

4.3 Indoor Air Sampling

Based on the sub-slab soil gas analytical results discussed in Section 4.2, ATC collected an indoor air
sample (Indoor Air #1) at the former location of sub-slab soil gas point SGMP-2 on January 27, 2012.
The indoor air sample was collected in a 6-liter Summa canister over an 8-hour timeframe. The
canister was placed approximately 3 feet above grade. The Summa canister was equipped with a
choke to regulate the sample time. At the end of sampling, the Summa canister was packaged and
submitted to Air Toxics Ltd. for analysis of VOCs by EPA Method TO-15.

The results of the laboratory analyses indicated detectable concentrations of multiple constituents in
indoor air. The indoor air analytical data is summarized in Table 5 and depicted on Figure 7. The
indoor air laboratory analytical report is included in Appendix C. NCDENR guidance for indoor air
evaluation calls for initial comparison of individual constituent concentrations to the IHSB VISLs for
residential or industrial/commercial indoor air. The results of this comparison for the subject site
indicated an exceedence of residential levels for benzene, but no exceedences of
industrial/commercial levels. If concentrations exceed the IHSB VISLs, NCDENR guidance calls for
a cumulative risk evaluation. ATC performed a cumulative risk calculation for the indoor air data
collected at the subject site in accordance with NCDENR protocol. The calculations are summarized
in Table 6. The results of the calculations for residential and industrial land use and a discussion of
how the results fall into the NCDENR regulatory framework are detailed below.

Although the property is not currently used for residential purposes, ATC performed an evaluation for
a residential scenario for the client’s use in the event future residential land use is considered. Note
that NCDENR applies residential risk goals to commercial structures where children spend significant

time such as schools and day care facilities. The cumulative risk evaluation based on a residential
land use scenario for the subject site indicated a carcinogenic risk of 3.1x10-6 and non-cancer hazard
index of 4.9x10-2. This hazard index value does not require further action. For carcinogenic risk
between 10-6 and 10-4, NCDENR requires a minimum of two sampling events, at least one of which
must be during worst-case (winter) conditions. If both events show no exceedences of a 10-4 risk
level, no further action is required.

For an industrial/commercial land use scenario, the cumulative risk evaluation indicated a
carcinogenic risk of 6.0x10-7 and non-cancer hazard index of 1.1x10-2. This hazard index value does
not require further action. For carcinogenic risk less than 10-6, NCDENR requires no further action if
the sample was collected during worst-case (winter) conditions.

As described above, the NCDENR guidance for indoor air evaluation refers to sampling during worst-
case (winter) conditions. Winter conditions are defined by NCDENR as highs of less than 60ºF.
Although the sampling at the subject site was conducted during typical winter months, the high on the
date of the sampling was 69 ºF. As such, the sampling did not meet the NCDENR criteria for “worst-
case”. However, based on ATC’s extensive experience with indoor air sampling in this region, ATC
would not expect indoor air concentrations to increase by more than an order of magnitude at the
most during colder weather, and likely may not increase at all. Since the concentrations detected at
the subject site were two to three orders of magnitude below the levels requiring mitigation, ATC
does not consider it likely that sampling during colder weather would substantially affect overall
conclusions regarding the risk of vapor intrusion for the site.

5.0 CONCLUSIONS

The site was occupied by a textile mill from the early 1900’s until the 1980’s. Environmental
investigations have been on-going since 1986 shortly following shutdown of the mill. Prior soil and
groundwater sampling indicated petroleum and chlorinated VOC impacts to soil and groundwater.
The majority of source area impacted soil was removed during demolition of the former mill and
construction of the existing retail/office building in 1990. Some isolated areas of impacted soil may
remain, but the most significant remaining impacts consist of generally low levels of VOCs in
groundwater. The primary constituent of concern in groundwater is 1,1-DCE. NCDENR has not
required sampling or other investigation at the site in recent years due to a low priority ranking within
the IHSB program; however, the release incident remains open and has not been issued NFA status.

ATC collected groundwater samples from seven existing monitoring wells to evaluate current
contaminant levels in groundwater. The results of the sampling indicated levels higher than the prior
sampling in April 2011, but generally within the range of historical concentrations. The remedial
goals for issuance of an NFA for the site are the NC 2L Standards. Exceedences of 2L Standards
were identified for 1,1-DCE and 1,1-DCA in multiple wells.

The most significant potential exposure pathway whereby current site occupants could be exposed to
the remaining contamination is the vapor intrusion pathway. As such, ATC focused on evaluation of
this pathway during the Phase II ESA. The results of the groundwater sampling indicated
exceedences of IHSB VISLs for residential and industrial/commercial groundwater. Sub-slab soil gas
sampling was also completed which also indicated exceedences of IHSB VISLs for residential and
industrial/commercial soil gas. Indoor air sampling was conducted in the area of primary vapor
intrusion concern identified based on the soil gas sampling. Note that indoor air data generally
override groundwater and soil gas data from a risk assessment perspective; as such, the indoor air data
should be of primary focus for concluding whether vapor intrusion poses a significant risk.

A cumulative risk evaluation was performed to evaluate the indoor air analytical data in accordance
with NCDENR guidance. Cumulative risk was calculated for both carcinogenic and non-cancer
(hazard index) exposures. No exceedences of non-cancer exposure limits were identified for either a
residential or industrial/commercial scenario. For carcinogenic exposure, the cumulative risk
evaluation indicated risk levels of 6.0x10-7 for an industrial/commercial scenario and 3.1x10-6 for a
residential scenario. These levels are two to three orders of magnitude below the level established by
NCDENR requiring mitigation (1.0x10-4). Based on the levels detected, NCDENR does recommend
additional confirmatory sampling during worst-case (winter) conditions; however, since
concentrations during the recent sampling were significantly below levels requiring mitigation, ATC
considers it unlikely that concentrations would increase to a level representing a significant risk.

Matrix spike (MS) and matrix spike duplicate (MSD) samples are chosen and tested at random from an analytical batch of "like" matrix to check for possible matrix effect. The MS and MSD will provide site specific matrix data for those samples spiked by the laboratory and may be applicable to
other samples of similar matrix from the site. Since the MS and MSD are chosen at random from an analytical batch, the sample chosen for spike purposes may or may not have been a sample submitted in this sample delivery group.
The validity of the analytical procedures for which data is reported in this analytical report is determined by the Laboratory Control Sample (LCS) and the Method Blank (MB). The Laboratory Control Sample (LCS) and the Method Blank (MB) are processed with the samples and the MS/MSD
to ensure method criteria are achieved throughout the entire analytical process. If insufficient sample is supplied for MS/MSD, a Laboratory Control Sample (LCS) and a Laboratory Control Sample Duplicate (LCSD) are reported with the analytical batch and serve as the batch quality
control (QC).
Results are reported on a Wet Weight Basis unless otherwise noted in the sample unit field as -dry.
The collection of samples using encores, terracores or other field collection devices may result in inconsistent initial sample weights for the parent
sample and MS/MSD samples.
The MS/MSD recovery and precision data are calculated based on detected spike concentrations that are adjusted for initial sample weights. As a result of the variability between initial sample weights, the calculated RPD may have increased bias.
Any other exceptions associated with this report will be footnoted in the analytical result page(s) or the quality control summary page(s).
Please do not hesitate to contact us if you have any questions or comments pertaining to this data report. Please reference the above Certificate of Analysis Number.
This report shall not be reproduced except in full, without the written approval of the laboratory. The reported results are only representative of the samples submitted for testing.
Accutest Gulf Coast is pleased to be of service to you. We anticipate working with you in fulfilling all your current and future analytical needs.

LABORATORY NARRATIVEModified TO-15 Full Scan/SIMATC Associates, Inc.Workorder# 1201510
Laboratory Services Since 1989
One 6 Liter Summa Canister (SIM Certified) sample was received on January 31, 2012. The laboratory
performed analysis via modified EPA Method TO-15 using GC/MS in the Full Scan and SIM
acquisition modes. The method involves concentrating up to 1.0 liters of air. The concentrated aliquot
is then flash vaporized and swept through a water management system to remove water vapor.
Following dehumidification, the sample passes directly into the GC/MS for analysis.
This workorder was independently validated prior to submittal using 'USEPA National Functional
Guidelines' as generally applied to the analysis of volatile organic compounds in air. A rules-based,
logic driven, independent validation engine was employed to assess completeness, evaluate pass/fail of
relevant project quality control requirements and verification of all quantified amounts.
Method modifications taken to run these samples are summarized in the table below. Specific project
requirements may over-ride the ATL modifications.

TO-15 (statistical MDL less than the LOQ). The
concentration of the spiked replicate may have exceeded
10X the calculated MDL in some cases
Receiving Notes
There were no receiving discrepancies.
The results for each sample in this report were acquired from two separate data files originating from
the same analytical run. The two data files have the same base file name and are differentiated with a
"sim" extension on the SIM data file.

Laboratory Services Since 1989
All Quality Control Limit exceedances and affected sample results are noted by flags. Each flag is
defined at the bottom of this Case Narrative and on each Sample Result Summary page.
Due to the linear calibration range of the instrument, the reporting limit for Chloromethane was raised
from 0.1ppbv to 0.5ppbv.
Eight qualifiers may have been used on the data analysis sheets and indicates as follows:
B - Compound present in laboratory blank greater than reporting limit (background subtraction
not performed).
J - Estimated value.
E - Exceeds instrument calibration range.
S - Saturated peak.
Q - Exceeds quality control limits.
U - Compound analyzed for but not detected above the reporting limit.
UJ- Non-detected compound associated with low bias in the CCV and/or LCS.
N - The identification is based on presumptive evidence.
File extensions may have been used on the data analysis sheets and indicates
as follows:
a-File was requantified
b-File was quantified by a second column and detector
r1-File was requantified for the purpose of reissue
