Mid -Atlantic Associates, Inc. (Mid -Atlantic) performed a Stockpile Assessment at the Northern Telecom
redevelopment site (subject site) located in Durham, North Carolina (Drawing 1). The subject site is
comprised of three parcels totaling 94.89 acres located within the Research Triangle Park (RTP) area of
Durham, North Carolina (Drawing 2). The site has been used for industrial purposes since at least
1979. The subject site is developed with unoccupied commercial office/warehouse buildings, parking
lots, storage structures, two fire suppression water tanks and associated pump buildings, guard shack,
tennis and volleyball courts, and cemetery.
The redevelopment consists of primarily fill areas, with some cut areas located around the existing
structures where utilities will be installed. The soil in these areas is being excavated and reused on -site
if geotechnically usable. Excavated material that in not geotechnically usable is planned to be wasted
on -site in a grassy area located on the western portion of the property (Drawing 2). After the stockpiled
material is spread in the grassy area, the area will be seeded and maintained as a grass landscaped
area. The stockpile currently contains approximately 600 cubic yards of cut material.
This report details the October 2020 stockpile and grass area sampling activities conducted on the
subject site. The objective of this assessment was to determine if the stockpiled cut material was
suitable for reuse in the grassy area where the soil is planned to be spread. The assessment was
conducted in accordance with the Environmental Management Plan dated September 17, 2020.

The opinions included herein are based on our experience and the information obtained during the
study. This report is based on limited observations made on the dates noted using the procedures
described herein. If additional information becomes available, we request the opportunity to review
the information, reassess the potential environmental concerns and modify our conclusions and
recommendations, if appropriate.
SUMMARY OF FIELD ACTIVITIES
On October 6, 2020, a composite soil sample was collected from stockpiled cut material located on -
site and four grab samples were collected from the grassy area where the cut soils are planned to be
spread. The estimated volume of the stockpiled soil is approximately 600 cubic yards. The
composite sample (SP-1) was collected from the stockpile and consisted of five aliquots from varying
depths (Drawing 3). The sample was analyzed for semi -volatile organic compounds (SVOCs) and
RCRA Metals (plus hexavalent chromium). One grab sample was also collected along with each of
the composite samples and analyzed for volatile organic compounds (VOCs).
Mid -Atlantic also collected four grab soil samples from just below the surface at approximately 0.5
feet below land surface (bls) from the grass area where the stockpiled soil is planned to be spread
(Drawing 4). The four grab samples (PP-GA-1 through PP-GA-4) were analyzed for VOCs, SVOCs,
RCRA Metals (plus hexavalent chromium).
Soil cuttings from each stockpile soil boring were screened using a photoionization detector (PID) to
evaluate if VOCs were detected in soil during sample collection activities. A portion of each soil sample
was removed from the sampling device and placed in a pre -labeled, plastic "Ziploc" bag. After several
minutes, the gas contained in the "headspace" or void area within the bag was screened with a PID.
The PID was also used for air monitoring in accordance with provisions in the site health and safety plan
(HASP). The soil samples collected for laboratory analysis were removed from the sampling device and
placed directly into laboratory supplied sample jars. Samples were collected from a depth of 1 to 2 feet
into the stockpile and from 0.5 to 1 foot bls in the grass area. Samples could not be collected further into
the stockpile due to auger refusal on rocks and debris. VOCs were not detected in any of the soils
screened with the PID above 1 part per million (ppm).
Soil samples were submitted for laboratory analysis of VOCs by EPA Method 8260, SVOCs by EPA
Method 8270, eight RCRA metals by EPA Methods 7471A and 6010B, and hexavalent chromium by
EPA Method 7199. One duplicate soil sample (DUP-SP) was collected from composite soil sample
SP-1. Soil samples were shipped to Pace Analytical Laboratory (Pace) of Huntersville, North Carolina
for laboratory analysis as shown on the chain of custody record provided in Appendix A.
SUMMARY OF LABORATORY ANALYTICAL RESULTS
Soil samples were compared to the Residential Preliminary Soil Remediation Goals (PSRGs), the
Protection of Groundwater PSRGs, and the Industrial PSRGs. As summarized in Table 1, total
chromium was detected in each of the stockpile and grass area samples, and the duplicate sample
at concentrations exceeding the Residential, Industrial/Commercial, and Protection of Groundwater
ft Mid Atlantic

PSRGs for total chromium. The soil samples with the highest total chromium concentrations in each
area [SP-01 at 8.4 milligrams per kilogram (mg/kg) and PP-GA-1 at 33.9 mg/kg] were speciated for
hexavalent chromium and the concentrations were below the laboratory reporting limits. The
speciation results indicate the chromium concentrations identified in the soil samples consist
primarily of trivalent chromium. Neither the speciated hexavalent chromium concentrations nor the
remaining trivalent chromium concentrations identified in the samples exceed the PSRGs. Arsenic
was detected in samples PP-GA-1, PP-GA-3, and PP-GA-4 at concentrations exceeding the
Residential and Industrial/Commercial PSRGs, but below the Protection of Groundwater PSRG.
Arsenic was detected in samples PP-GA-2, SP-01 and the duplicate sample DUP-SP at
concentrations exceeding the Residential PSRG but below the Protection of Groundwater and
Industrial/Commercial PSRGs. Arsenic is a metal that is found naturally occurring in North Carolina
soils. According to the North Carolina Department of Agriculture and Consumer Services (NCDA),
an average concentration of 4.5 mg/Kg of arsenic was detected in laboratory testing of 3,286 soil
samples collected across North Carolina between 2005 and 2007 (NCDA, 2008). Furthermore, the
EPA notes that arsenic concentrations typically range from four to nine mg/Kg in most soils (EPA,
2003). According to the laboratory analysis, the arsenic concentrations detected in the assessment
samples collected from the subject site fall within levels believed to be found naturally in North
Carolina soils. Barium, cadmium, lead, and mercury were detected in some or all of the stockpile
and grass area samples, and the duplicate sample at concentrations above laboratory method
detection limits but below the PSRGs, and at similar concentrations to those detected in previous
soil samples collected at the subject site. As summarized in Table 1, VOCs and SVOCs were not
detected in any of the samples above to the laboratory detection limits.
Mid -Atlantic completed risk calculations for the stockpiled soil using the maximum concentrations
identified in the primary and duplicate samples. The risk calculations were completed to evaluate the
residential and non-residential worker scenarios. The Brownfields Program allows a maximum cancer
risk sum for all carcinogens of 1.0E-04 and a maximum cumulative hazard index (HI) of 1.0 for all non -
carcinogens for direct contact with soil. The HI is the sum of the hazard quotient (HQs) calculated for
each compound detected above the reporting limit.
Cancer risk sums and cumulative non -cancer hazard indexes were determined using the maximum
concentrations identified in the soil samples (Appendix B). The residential cancer risk sum was 7.1 E-
06, below the target cancer risk sum of 1.0E-04. The residential cumulative non -cancer hazard index
was 1.6E-01, below the target cancer risk sum of 1.0. The non-residential worker cancer risk sum was
1.6E-06, below the target cancer risk sum of 1.0E-04. The non-residential worker cumulative non -
cancer hazard index was 1.2E-02, below the target index of 1.0.
The objective of this assessment was to determine if the on -site stockpiled cut material is suitable to be
spread in the grass area located in the western portion of the subject site. Based on review of the data
collected during this assessment Mid -Atlantic concludes:
• With the exception of arsenic and total chromium detected in all of the soil samples, metals
concentrations in the stockpiled cut material and the grass area do not exceed the PSRGs.

The arsenic concentrations detected in the soil samples and the duplicate fall within levels
believed to be found naturally in North Carolina soils.
• Soil samples SP-01 and PP-GA-1 were speciated for hexavalent chromium and the results
are below the laboratory reporting limits;
• VOCs and SVOCs were not identified in the samples at concentrations above the laboratory
detection limits; and
• The calculated cancer risk sums and cumulative non -cancer hazard index calculated using the
maximum concentrations identified in the soil samples did not exceed the target cancer risk sum
of 1.0E-04 or the target cumulative non -cancer hazard index of 1.0 when calculated for both the
residential and non-residential worker scenarios .
Based on the totality of the data collected during this investigation, it appears that the stockpiled cut
material is suitable for spreading in the noted grass area. As such, Mid -Atlantic recommends that the
stockpiled soil located on -site be approved for spreading in the grass area located on the western
portion of the subject site.

QUALIFIERS
Project: Park Pointe Stockpile
Pace Project No.: 92499338
DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL -Adjusted Method Detection Limit.
PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean -Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.
TNI -The NELAC Institute.
ANALYTE QUALIFIERS
BC The same analyte was detected in an associated blank at a concentration above 1/2 the reporting limit but below the
laboratory reporting limit.
C8 Result may be biased high due to carryover from previously analyzed sample.
D6 The precision between the sample and sample duplicate exceeded laboratory control limits.
IK The recalculated concentration of the calibration standard(s) did not meet method acceptance criteria; this result should
be considered an estimated value.
M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.
ML Matrix spike recovery and/or matrix spike duplicate recovery was below laboratory control limits. Result may be biased
low.
v2 The continuing calibration verification was below the method acceptance limit. The analyte was not detected in the
associated samples and the sensitivity of the instrument was verified with a reporting limit check standard.
v3 The continuing calibration verification was below the method acceptance limit. Any detection for the analyte in the
associated samples may have low bias.

QUALIFIERS
Project: PARK POINT GRASS AREA
Pace Project No.: 92499316
DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL -Adjusted Method Detection Limit.
PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean -Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.
TNI -The NELAC Institute.
ANALYTE QUALIFIERS
BC The same analyte was detected in an associated blank at a concentration above 1/2 the reporting limit but below the
laboratory reporting limit.
C8 Result may be biased high due to carryover from previously analyzed sample.
IK The recalculated concentration of the calibration standard(s) did not meet method acceptance criteria; this result should
be considered an estimated value.
M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.
ML Matrix spike recovery and/or matrix spike duplicate recovery was below laboratory control limits. Result may be biased
low.
v2 The continuing calibration verification was below the method acceptance limit. The analyte was not detected in the
associated samples and the sensitivity of the instrument was verified with a reporting limit check standard.
v3 The continuing calibration verification was below the method acceptance limit. Any detection for the analyte in the
associated samples may have low bias.
