Research Triangle Park, North Carolina
1.0 INTRODUCTION
CBRE is pleased to submit our Limited Phase II Environmental Site Assessment (Assessment) of
the vacant industrial facility located at 4001 E. Chapel Hill -Nelson Highway, Research Triangle
Park, North Carolina herein referred to as the "Subject".
l.l. Background and Purpose
The property, which is situated in an urban area characterized by light industrial and
commercial office development, consists of an approximately 99-acre, four -parcel
property improved with a 37-year-old (built in 1979, with several additional in the 1980s),
approximate 700,000 square -foot (SF) office/warehouse (former industrial) facility. Prior
to the construction of the existing improvements, the site was mostly undeveloped, wooded
land with minor residential improvements.
The purpose of this Assessment was to investigate a Recognized Environmental Condition
(REC) identified in a Phase I Environmental Site Assessment (ESA) prepared by CBRE,
dated February 5, 2016. Specifically, the following REC was identified, which warranted
investigation at this time.
Past Use of Property for Circuit Board Manufacturing
Although approximately 350,000 SF of the facility is now designated as warehouse, that
same area (the southern portion of the facility) was formerly used as manufacturing space
when the facility was occupied by Nortel. According to the site contact, among other
operations, circuit board assembly was conducted at the facility from approximately
1979/1980 to the late-1990s. These types of manufacturers typically use chlorinated
solvents as parts degreasers. Chlorinated solvents include tetrachlorothene, trichorothene,
1,2-dichloroethene and l,l,l-trichloroethane. The improper storage, usage and disposal
of chlorinated solvents commonly results in subsurface impacts. Although there are no
known releases of such solvents at the subject property, the historical use of the facility as
a manufacturer of circuit boards and electronics in general is indicative of a significant
environmental concern to the property. Also, the facility formerly operated as a Resource
Conservation and Recovery Act (RCRA)-Small Quantity Generator (SQG) of hazardous
waste, with several violations/enforcement actions on record in the 1980s and early
1990s.
Additionally, the following Business Environmental Risk (BER) was identified:
Monitoring Well
One inactive apparent monitoring well was observed just east of the central side of the
facility. The purpose of the well is unknown, but the site contact indicated that it is likely a
"test well." The well is fitted with secured cap, and appeared to be quite old (a stamp on
the cap indicated it was from pre-2000). Wells such as the one observed can act as
conduits to groundwater and contaminate same if harmful materials are permitted to enter
the well.

1.2. Limitations and Exceptions
• The scope of work completed was designed solely to meet the needs of the Client.
CBRE shall not be liable for any unattended usage of this report by another party.
• No subsurface investigation can wholly eliminate uncertainty regarding the presence of
contamination on a property. This Assessment was designed to reduce, but not
eliminate the potential for RECs at the Subject, within reasonable limits of time and
cost. The ESA is not intended to be exhaustive or all-inclusive and does not represent
a guarantee of the identification of all possible environmental risk.
Client is advised that if the ESA is obtained with the intent of qualifying the purchaser
as an innocent landowner, contiguous property owner, or bona fide prospective
purchaser under CERCLA, there will be continuing obligations of due care and
responsiveness and additional legal requirements that likely apply to such status.
CBRE accepts and undertakes no responsibility as to such requirements and advises
that counsel be separately consulted with respect to such requirements.
1.3. Special Terms and Conditions
There are no special terms and conditions associated with this assignment.
1.4. User Reliance
This investigation was conducted on behalf of and for the exclusive use of the Client. This
report, and the findings contained herein, shall not, in whole or part, be disseminated or
conveyed to or used by any other party without the prior written consent of CBRE.
2.0 PROPERTY DESCRIPTION

4.0 SUBSURFACE INVESTIGATION
4.1. Utility Clearance
Prior to conducting any subsurface drilling, CBRE contacted the North Carolina
underground utility mark -out system. In addition, CBRE retained the services of Probe
Utility Locating, LLC, a private utility locator, to "clear' CBREs boring locations for
underground utilities. The mark out for the boring locations was conducted using ground
penetrating radar (GPR) and electromagnetic equipment.
4.2. Soil Borings
Soil Sampling
CBRE directed the advancement of eight (8) borings on the Subject for investigation of the
above referenced REC. The borings were advanced by Innovative Environmental
Technologies, Inc. (IET) using a direct -push drill rig. Prior to the advancement of each
boring, all down -hole drilling equipment was decontaminated by IET in accordance with
U.S. EPA protocols and good commercial and customary practice.
S13-1 through SB-6 were advanced to 5 feet below ground surface (bgs) in the former
manufacturing area located in the southern portion of the building. SB-7 and S13-8 were
advanced to up to 17 feet bgs to the south and southwest (downgradient) of the building.
No soil samples were collected from S13-7 and SB-8, as these borings were not locating in
the immediate vicinity of a potential source area.
Sample locations are shown on the Sample Location Plan, attached as Figure 1 in
Appendix A.
Soil samples were collected at continuous 5-foot intervals using a macro -core sampler
and inspected for evidence of VOC contamination using a PID. No staining, odors or PID
readings above background levels were identified in any of the borings. Observed soil
conditions encountered in the borings consisted of predominantly stiff, brown, fine sandy
silt to approximately 10 to 12 feet bgs. Very dense, silty sand was identified near the
bottom of SB-7 and S13-8. Refusal was encountered in SB-7 and SB-8 at depths of 17 feet
bgs and 15 feet bgs, respectively. Groundwater was encountered at approximately 12
feet bgs in S13-7. No groundwater was encountered in the remaining soil borings. PID
readings and detailed soil descriptions are provided on the boring logs presented in
Appendix B.
CBRE collected one soil sample from S13-1 through SB-6 for laboratory analysis. Based on
the lack of field indications of soil impacts, a shallow sample (1 foot bgs) was collected in
an effort to identify a surface release. Collected samples were transferred to laboratory
supplied sample containers, packed on ice in a cooler and shipped under proper chain of
custody to TestAmerica Laboratories, Inc. (TestAmerica) in Nashville, Tennessee. Soil
samples were analyzed for VOCs by EPA Method 8260B and RCRA metals by EPA
Method 6010D/7471 B.

Research Triangle Park, North Carolina
Groundwater Sampling
In order to evaluate groundwater quality at the Subject, SB-7 was converted into a
temporary groundwater monitoring well (TMW-1) consisting of one -inch inside diameter
poly -vinyl chloride (PVC) well screen and riser pipe. A stainless steel check valve with
dedicated, disposable tubing was utilized to purge the wells and collect the groundwater
sample. Shallow refusal was encountered in three borings in the vicinity of SB-8;
therefore, no groundwater sample was able to be collected.
The groundwater sample was transferred to laboratory supplied sample containers,
packed on ice in a cooler and shipped under proper chain of custody to TestAmerica.
The sample was analyzed for VOCs by EPA Method 8260B and dissolved RCRA Metals by
EPA Method 6010D/7470A. Upon completion of sampling, all borings were backfilled
flush to grade with bentonite and the ground surface repaired with concrete.
Sub -Slab Vapor Sampling
CBRE advanced six (6) sub -slab vapor probes adjacent to each of the interior soil borings
noted above (former manufacturing area). The soil vapor probe locations denoted as
SG-1 through SG-6 are depicted on Sample Location Plan in Appendix A.
The sub -slab vapor probes were advanced by CBRE using hand-held sampling equipment,
six inches beneath the concrete slab. A sacrificial vapor point connected to Teflon tubing
was inserted into each borehole. The annular space of the borehole was filled with sand
to the base of the concrete slab, followed by a hydrated bentonite seal. Prior to sampling,
the tubing system was purged of ambient air with a low -flow pump. The samples were
collected from each point into laboratory supplied 6-liter summa canisters equipped with
regulators and manometers to ensure a flow rate of less than 200 ml/min.
To serve as a quality assurance/quality control (QA/QC) device, a tracer gas was used to
serve to verify the integrity of the soil vapor probe seal. Helium was used as the tracer
gas. A portable monitoring device was used to analyze the integrity of the seal. After
adjustments to prevent infiltration and prior to sampling, each location was proven to not
show a significant presence of Helium.
Upon completion of sampling the vapor points were removed, the boreholes were
backfilled and the ground surface was repaired. The summa canisters where shipped
under proper chain of custody to TestAmerica's Knoxville, Tennessee laboratory for
analysis of VOCs in accordance with EPA method TO-15.
4.3. Monitoring Well Abandonment
CBRE directed IET to perform the abandonment of the on -site monitoring well in
accordance with the North Carolina Department of Environmental Quality (NCDEQ)
guidelines. Specifically, the well abandonment will include the following procedures.
• Removal of the exposed steel riser pipe;
• Filling the well casing with a fluid bentonite grout mixture using a tremie pipe;

Research Triangle Park, North Carolina
• Restoring the ground surface to conform with the surrounding area.
A copy of the Well Abandonment Record is provided in Appendix C.
4.4. Discussion of Analytical Results
The soil, groundwater and sub -slab vapor sampling results for this Assessment are
discussed below. CBRE has compared the soil analytical data to the NCDEQ, Inactive
Hazardous Sites Branch Preliminary Soil Remediation goals (PSRGs) for protection of
groundwater, residential soil and commercial/industrial soil (updated October 2016).
In addition, metals data were compared to North Carolina background values
published in Elements in North American Soils, Second Edition (2005). Groundwater
data were compared to the North Carolina 2L Groundwater Standards (2L Standards).
Soil vapor data were compared to the NCDEQ, Division of Waste Management Soil
Gas screening levels (SGSLs) for residential and non-residential sites (updated October
2016. The analytical data are presented on Tables 1 through 3 in Appendix D. The
laboratory reports are provided in Appendix E.
Soil Analvtical Results
Soil analytical data indicate the presence of benzene in SB-1 (1') at a concentration
of 0.00166 mg/kg, which is below the most stringent PSRG (i.e. protection of
groundwater) of 0.0073 mg/kg. The data indicate that the remaining VOCs are not
present above the laboratory reporting limits (RSLs).
• Metals data indicate the presence of arsenic, barium, chromium and lead. A
summary of each constituent is provided as follows:
• Arsenic was detected in SB-3 (1') at a concentration of 2.32 mg/kg. The
detected concentration exceeds the residential PSRG but is within the range of
published North Carolina background levels.
• Barium was detected at concentrations ranging from 59.2 mg/kg to 121
mg/kg. The concentrations are well below the PSRGs and are consistent with
published North Carolina background levels.
• Chromium was detected at concentrations ranging from 6.88 mg/kg to 12.0
mg/kg. The concentrations are consistent with published North Carolina
background levels.
• Lead was detected at concentrations ranging from 11 .7 mg/kg to 22.6 mg/kg.
The concentrations are well below the PSRGs and are consistent with published
North Carolina background levels.

CBRE

4001 East Chapel Hill -Nelson Highway
Research Triangle Park, North Carolina
Groundwater Analytical Results
• Groundwater analytical data do not indicate the presence of VOCs in TMW-1
above laboratory reporting limits.
Barium was detected at a concentration of 222 /fig/L, which is well below the 2L
Standard of 700 pg/L.
Sub -Slab Soil Vapor Results
Soil vapor analytical data indicate the presence of numerous VOCs in SG-1 through
SG-6. Dichlorodifluoromethane (Freon 12) was detected in SG-2 and SG-5 at a
concentration of 1,100 Pg/m3, which exceeds the residential SGSL of 695 pg/m3.
However, the detected concentration is well below the applicable non-residential
SGSL of 8,760 pg/m3.
5.0 CONCLUSIONS AND RECOMMENDATIONS
The results of this Assessment are summarized below:
• Soil borings were advanced within and immediately downgradient of the former
manufacturing facility. In addition, six (6) soil samples, one (1) groundwater sample and six
(6) sub -slab vapor samples were collected for laboratory analysis.
• Soil analytical data indicated the presence of benzene in SB-1 (1'); however, the detected
concentration was below the PSRGs. Metals detected in SB-1 (1') through SB-6 (1') were
present at concentrations below the PSRGs and/or consistent with published North Carolina
background levels.
• Only barium was detected in groundwater. The detected concentration is well below the 2L
Standard.
• Dichlorodifluoromethane (Freon 12) was detected in two sub -slab vapor samples (SG-2 and
SG-5) at a concentration of 1,100 µg/m3, which exceeds the residential SGSL of 695
Ng/m3. However, the detected concentration is well below the applicable non-residential
SGSL of 8,760 µg/m3. Only trace concentrations of VOCs were detected in the remaining
sub -slab vapor samples. Based on the anticipated future commercial use of the Subject, the
level of Freon 12 detected in sub -slab vapor is appropriate for the site's intended use.
Based on the results of this Assessment, no additional investigation is recommended at this
time.
CBRE's conclusions and recommendations are based on the results this Assessment. This
Assessment was intended solely to investigate the REC identified in the Phase I Report. It was
not intended to satisfy the level of inquiry that may be necessary to support remedial solutions or
determine migration pathways related to a release from the REC.

Receipt
The samples were received on 1/12/2017 at 2:20 PM. The samples arrived in good condition and properly preserved.
Air - GC/MS VOA
Method(s) D1946, TO 15 LL, TO-14A, TO-15: EPA methods TO-14A and TO-15 specify the use of humidified "zero air" as the blank reagent
for canister cleaning, instrument calibration and sample analysis. Ultra -high purity humidified nitrogen from a cryogenic reservoir is used
in place of "zero air" by TestAmerica Knoxville.
Method(s) TO-15: The continuing calibration verification (CCV) associated with batch 140-7733 exhibited % difference of > 30% for
1,2,4-trichlorobenzene; however, the results were within the LCS acceptance limits. The EPA method requires that all target analytes in
the continuing calibration verification standard be within 30% difference from the initial calibration. According to the laboratory standard
operating procedure, the continuing calibration is acceptable if it meets the laboratory control sample acceptance criteria.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.
