SMARTER ENVIRONMENTAL SOLUTIONS
On behalf of the Town of Chapel Hill (Town), Hart & Hickman, P.C. (H&H) has prepared this
Work Plan to conduct Brownfields assessment activities at the Chapel Hill Police Department
Brownfields property (Brownfields Project No. 23022-19068) located at 828 Martin Luther King
Jr. Boulevard in Chapel Hill, Orange County, North Carolina (subject Site or Site). The Site is
comprised of one parcel of land that is approximately 10.24 acres in size and is developed with a
two-story approximately 35,000 square foot (sq ft) building located in the north -central portion of
the Site. The building and associated parking areas are currently used for police department
operations by the Town. A Site location map is provided as Figure 1, and the Site and surrounding
area are shown in Figure 2.
The Town is currently evaluating potential mixed -used redevelopment that may include a new
Municipal Services Center, residential housing, and/or retail. As part of the evaluation process,
the Town applied for entry into the North Carolina Department of Environmental Quality (DEQ)

Brownfields Program, and received eligibility (Brownfields Project No. 23022-19-068) via a
Letter of Eligibility dated October 1, 2019.
A brief summary of prior environmental assessment activities conducted at the Site is provided in
Section 2.0 below.
2.0 Site Background
Previous assessment activities indicated that the Site was initially used as a borrow pit from the
late 1950s to early 1960s, and then was used as a fill site by a previous owner for construction
debris and coal combustion products (CCPs) from the mid- 1960s to the mid- 1970s. In the early
1980s, the Town acquired the property and constructed the current police department building.
The Site consists of an upper level where the borrow pit was located which is now occupied by the
police department building and parking areas, and a lower level adjacent to Bolin Creek where the
Bolin Creek Trail is located. The upper and lower levels are separated by a steep embankment.
The Site layout and area of CCPs are depicted on Figure 2.
Assessment activities were conducted at the Site from 2013 to 2020 to investigate potential
environmental impacts associated with historical placement of structural fill containing CCPs. The
investigation activities included the collection and laboratory analysis of CCPs, groundwater, soil,
sediment, and surface water samples. Based on assessment activities, the primary compounds of
concern (COCs) detected in CCPs, shallow soil, and drainage pathway soil are certain metals.
Results of analysis of samples of CCPs indicate that arsenic, barium, manganese, mercury, and
selenium were detected above soil background levels and the DEQ Preliminary Soil Remediation
Goals (PSRGs). The most prevalent compound detected above soil background levels and PSRGs
in CCPs is arsenic.
In addition to COCs being identified in CCPs and soil, COCs have been detected in perched
groundwater zones within the fill material. However, groundwater assessment activities identified
limited to no impacts in the underlying unconfined aquifer downgradient of the fill area.
Assessment activities also identified no significant impacts to stream sediment or surface water in

Bolin Creek. Additional background information and the methods and results of previous
assessment activities are provided in the following documents:
• Phase I & Limited Phase II Environmental Site Assessment, Falcon Engineering, Inc., July
18, 2013;
• Phase II Remedial Investigation Report, H&H, January 26, 2017;
• Results of Data Gap Sampling Report, H&H, May 23, 2019; and
• Results of Post -Data Gap Assessment Report, H&H, December 1, 2020.
In 2020, interim remedial measures (IRMs) were implemented, which included excavation and
off -Site disposal of soil and exposed CCPs along Bolin Creek Trail, stabilization and cover of
exposed CCPs along the embankment between the upper and lower portions of the Site, and
temporary measures to address stormwater and erosion control in the area of the embankment.
Specifically, approximately 1,004 tons of soil/CCPs at the base of the embankment and along
Bolin Creek were excavated and transported off -Site for disposal. In addition, super silt fencing
and hydroseed were placed along the embankment, and a new stormwater diversion channel was
installed along portions of the top of the embankment to minimize the potential for future erosion
of soil/CCPs on the embankment. The interim measures are documented in an Interim Remedial
Measures Report prepared by H&H dated April 19, 2021.
Risk assessment activities performed after IRMs concluded that the Bolin Creek Trail is safe for
users. Under present conditions, CCP fill material at the Site is covered by at least 2 ft of soil
cover, with the exception of localized areas in the upper level with 1 to 2 ft of soil cover and
localized areas of exposed CCPs along the embankment where IRMs were implemented (see
Figure 2). Based on potential future redevelopment scenarios, the Town requested that H&H
perform additional risk assessment activities to evaluate further measures recommended to address
CCPs at the Site. The risk assessment recommended implementation of permanent measures to
address exposed CCPs along the embankment, potentially addressing isolated areas of soil impacts
if the Site is used for residential purposes, and managing CCPs through the implementation of land
use restrictions (LURs) and/or a DEQ-approved Environmental Management Plan (EMP), which

can all be implemented as part of Site redevelopment. Details associated with the risk assessment
activities are provided in a Risk Assessment Report dated October 7, 2021.
On March 30, 2022, H&H participated in a virtual meeting with the DEQ Brownfields Program
and Town personnel to discuss potential data gaps and the scope of Brownfields assessment
activities needed to address potential data gaps. On June 22, 2022, H&H participated in an
additional virtual meeting with the DEQ Brownfields Program to further discuss proposed
Brownfields assessment activities. The June 22nd meeting resulted in an email from DEQ
requesting assessment of groundwater, soil, and vapor intrusion. To address DEQ's request for
assessment at the Site, H&H submitted a Brownfields Assessment Work Plan (Work Plan) dated
July 21, 2022. Following review of the Work Plan, DEQ provided comments in an email dated
August 18, 2022. This Revised Work Plan has been prepared to address those comments, the
details of which are included in the following sections.
3.0 Brownfields Assessment Activities
The proposed Brownfields assessment activities will be performed in general accordance with the
DEQ Inactive Hazardous Sites Branch (IHSB) Guidelines for Assessment and Cleanup
(Guidelines) dated July 2021, the DEQ Division of Waste Management (DWM) Vapor Intrusion
Guidance dated March 2018, Brownfield's Vapor Intrusion Assessment Work Plan & Report
Checklist dated July 2021, and the most recent versions of the U.S. EPA Region IV Laboratory
Services and Applied Science Division (LSASD) Field Branches Quality System and Technical
Procedures guidance.
Prior to conducting field activities, H&H will contact North Carolina 811 One -Call, the public
utility locator service, to mark subsurface utilities at the Site. H&H will also contract a private
utility locator to identify and mark locations of sub -grade utilities in the vicinity of the proposed
assessment activities at the Site that may not be marked by the public locator.

3.1 Receptor Survey
H&H will perform a Brownfields receptor survey in accordance with DEQ Brownfields Section
guidance. The receptor survey will use the Brownfields Property Receptor Survey Form and will
include information about land use in the Site area including zoning. H&H will also conduct a
field search for water supply wells, basements, utility manways and chases, storm sewers, other
underground utilities, drains, and surface water within a 1,500 ft radius of the Brownfields property
boundaries.
3.2 Soil Assessment Activities
H&H proposes to advance one soil boring to evaluate subsurface conditions in the vicinity of a
diesel fuel aboveground storage tank (AST). The AST is associated with an emergency generator
located in the northern portion of the Site. Additionally, three shallow soil borings will be advanced
in the proposed stormwater pond area located in the eastern portion of the site. The approximate
location of the proposed soil borings are shown on Figures 3 and 4.
H&H will use a decontaminated stainless steel hand auger to advance the borings to a depth of
approximately 5 feet below ground surface (ft bgs). The soil borings will be logged for lithological
description and field screened for indication of potential impacts by observation for staining,
unusual odors, the presence of CCPs, and the presence of volatile organic vapors using a calibrated
photoionization detector (PID). One sample will be collected from each soil boring at a depth
interval interpreted most likely to be impacted based on field observations and PID readings. If
evidence of impacts are not observed, surficial soil samples (approximately 0-2 ft bgs) will be
collected.
The soil samples will be placed in dedicated laboratory -supplied sample containers, labeled with
the sample identification, date, and requested analysis, and placed in a laboratory -supplied cooler
with ice. The soil samples will then be submitted to Pace Analytical (Pace), a North Carolina
certified laboratory, under standard chain of custody protocols for analysis of volatile organic
compounds (VOCs) by EPA Method 8260 and semi-VOCs (SVOCs) by EPA Method 8270. Based

upon previous analytical data, the soil samples will also be analyzed for the Site -specific COCs:
arsenic, barium, beryllium, cadmium, total chromium, cobalt, copper, manganese, nickel,
selenium, thallium, and vanadium by EPA Method 6020, hexavalent chromium by EPA Method
7199, mercury by EPA 7471, and strontium by EPA Method 6010. Proposed laboratory analyses
are also provided in Table 1. Information pertaining to Pace's certifications and accreditations is
provided in Appendix A.
Following sampling activities, the soil borings will be properly abandoned and the surfaces will
be repaired similar to pre -sampling conditions. Additionally, the soil sample locations will be
recorded using a hand-held GPS unit.
3.3 Groundwater Assessment Activities
H&H proposes to sample all existing monitoring wells, which include an upgradient well (MW-
5), wells installed in perched water in the fill (MW-1, MW-lA, MW-8 and MW-9), wells
downgradient and cross -gradient of the fill area (MW-3A, MW-4A, MW-6, and MW-7), and a
well in bedrock below the fill (MW-11D). The locations of the existing monitoring wells are
depicted on Figures 3 and 4.
Prior to groundwater sampling, H&H will open the monitoring wells to allow for water level
equilibration. Following equilibration, water levels will be collected from monitoring wells for
the generation of a potentiometric surface map. H&H will collect groundwater samples using low
flow/low stress purging techniques using a peristaltic pump and disposable polyethylene tubing or
a bladder pump if the depth to water is below 30 ft bgs. The intake point of the pump tubing will
be placed approximately in the mid -portion of the screened interval of the well and groundwater
will be removed at a rate no greater than 200 milliliters per minute. H&H will use a water quality
meter to measure pH, temperature, dissolved oxygen, oxidation reduction potential, turbidity, and
specific conductivity at 3 to 5-minute intervals during purging. Purging will be considered
complete when water quality parameters stabilize (i.e., pH ± 0.1 SU, conductivity varies no more
than 5%, and turbidity is less than 10 NTUs). If turbidity cannot be reduced to less than 10 NTUs,
a filtered and unfiltered sample will be collected for analysis of metals.

Once groundwater parameters stabilize, a groundwater sample from each monitoring well will be
collected directly from the pump tubing into laboratory -supplied sample containers except that
samples for VOC analysis that are collected with a peristaltic pump will be collected using the
"soda straw" method to minimize volatile loss through the peristaltic pump head. Specifically, for
the soda straw method, the sample tubing will be disconnected from the outflow side of the pump
head, the tubing will be removed from the well, and then the sample containers will be filled by
reversing the flow direction of the peristaltic pump. The sample containers will be labeled with
the sample identification, date, and requested analysis, and then placed in a laboratory -supplied
cooler and iced. The samples will be delivered to Pace under standard chain of custody protocols
for analysis of VOCs by EPA Method 8260 (including low level 1,4-dioxane via Selected Ion
Monitoring [SIM]), SVOCs by EPA Method 8270, hexavalent chromium by EPA Method 7199,
strontium by EPA Method 6010, and an additional inorganics analytes list determined by DEQ
(DEQ Analyte List). The DEQ Analyte List with analytical methods is provided in Appendix B
and was derived from Duke Energy's monitoring plan for an industrial landfill at the Marshall
Steam Station facility in Catawba County, North Carolina that is permitted to receive CCPs as well
as other materials. Note that H&H proposes to omit calcium, iron, lead, magnesium, and silver
from the proposed DEQ Analyte List. These analytes are not considered COCs because
groundwater samples were previously collected for analysis of these metals and they were not
detected above standards as documented in previous reports. Additionally, after the initial
assessment activities at the Site, DEQ IHSB provided concurrence with the omission of these
analytes for further assessment activities that are documented in the January 2017 Phase II
Remedial Investigation Report. However, at the request of the DEQ Brownfields Program
following their review of the July 2022 Work Plan, antimony, boron, molybdenum, thallium,
vanadium, and zinc have been added to the proposed DEQ Analyte List.
Table 1 summarizes the proposed groundwater samples and associated analyses. Information
pertaining to Pace's certifications and accreditations is provided in Appendix A.

3.4 Vapor Intrusion Assessment Activities
H&H proposes to conduct sub -slab soil vapor and exterior soil gas assessment activities to evaluate
the potential for structural vapor intrusion into current and potential future Site structures. The
approximate locations of the proposed sub -slab soil vapor samples (2) and the exterior soil gas
samples (7) are shown on Figures 3 and 4, and are described below:
• Two sub -slab vapor samples will be collected from the western and eastern portions of the
existing police building;
• One soil gas sample will be collected in the footprint of a conceptual office building; and
• Six soil gas samples will be collected in the footprint of a conceptual multi -family
residential building with an integrated parking garage.
H&H proposes to install each sub -slab vapor point by utilizing a hammer drill and 5/8-inch
diameter drill bit to advance the boring through the concrete slab. Following concrete borehole
advancement, loose concrete cuttings will be removed from the boring using a bottlebrush and
vacuum with a high -efficiency particulate air (HEPA) filter. A Cox -Colvin Vapor PinTM (vapor
pin) assembly (brass sampling point and silicone sleeve) will be seated in the borehole using an
installation/extraction tool and hammer. The vapor pins will be connected at the surface with 1/4—
inch new and dedicated Teflon® tubing and installed as temporary sub -slab vapor points. Sample
points will be allowed at least 2 hours following installation to equilibrate prior to sampling.
H&H will install each exterior soil gas point to a depth of approximately 5.5 ft bgs using a hand
auger. The soil gas points will each be installed with a 6-inch long 0.010-inch slot stainless steel
screen set at the base of the boring connected to the surface with 1/4-inch new and dedicated
Teflon® tubing. The annular space will be filled with filter sand followed by a bentonite seal to
prevent short-circuiting of air from the surface. The soil gas points will be installed as temporary
points and will be allowed to equilibrate for a minimum of 48 hours after installation and prior to
sample collection described below.

Prior to sample collection, a Landtec Gem 5000' or equivalent device will be connected to the
sample Teflon® tubing and field measurements of static and differential pressure readings will be
collected from each sampling point. After pressure readings are collected, a "shut-in" test will be
conducted on the sampling train and helium leak checks will be conducted at each sampling point.
The purpose of the shut-in test and helium leak check described below are to ensure that short
circuiting with ambient air does not occur during sampling. A description of the shut-in test and
helium leak testing procedures is provided below.
The shut-in test will be conducted by connecting the flow regulator with the vacuum gauge to the
Summa® canister and sealing the flow regulator with the laboratory provided brass cap. Once the
sampling train is "closed", the sample valve on the Summa® canister will be opened and the
reading on the vacuum gauge will be recorded. The Summa® canister sample valve will then be
closed, and the vacuum gauge will be observed to ensure no vacuum loss occurs. If the vacuum
reading remains the same, the shut-in test will be considered successful. If vacuum loss occurs,
the flow regulator and/or brass cap will be reseated, and the shut-in test will be repeated until the
vacuum reading remains stable.
Following a successful shut-in test, a leak check will be conducted by constructing a shroud around
the sample train at each sampling point and flooding the air with helium gas. Helium
concentrations inside the shroud will be measured using a calibrated helium gas detector and
maintained at concentrations of approximately 15% to 30% for the duration of the leak check.
Using a syringe and three-way valve, the Teflon® sample tubing will be purged using the Landtec
Gem 50008 (or equivalent device) while concurrently collecting field measurements of pressure,
oxygen, carbon dioxide, and methane (percent by volume and percent lower explosive limit).
Following collection of these measurements, a sample will be collected from the sample tubing
outside the shroud into a Tedlar bag and analyzed using the helium gas detector to ensure that
helium concentrations are less than 10% of the helium concentrations measure within the shroud.
After completion of the helium leak check, mercury vapor samples will be collected using an in -
line laboratory -provided sorbent tube sampler. An air sampling pump and a flow meter will be
used to collect the sample through the sample train at a constant rate of approximately 200

milliliters per minute over a laboratory -specified timeframe to achieve the suitable laboratory
method detection limits. Due to the potential presence of background mercury in air, one field
blank will be prepared during the sampling event. The field blank will be prepared by opening the
sample media (sorbent tube) in an exterior field location and sealing it without collection of gas
through the media.
Following sample collection for mercury analysis, the sample media will be shipped under
standard chain -of -custody protocols to EMSL Analytical, Inc. (EMSL) for analysis of elemental
mercury by National Institute for Occupational Safety and Health (NIOSH) Method 6009. The
sample will be collected over a period of time and at a flow rate for the laboratory to achieve a
minimum reporting limit for mercury below the July 2022 DEQ Residential Sub -Slab and Exterior
Soil Gas Screening Level (SGSL) of 2.1 micrograms per cubic meter (µg/ru).
Following mercury sampling, samples for VOC analysis will be collected from the sampling point
using individually -certified 1-liter or 3-liter stainless steel Summa® canisters connected to an air-
flow regulator calibrated by the laboratory for collection of a sample at a rate of approximately
100 milliliters per minute. To conduct the sampling, the intake valve on the Summa® canister will
be fully opened to begin collection of the sample and vacuum readings on the Summa® canister
will be recorded prior to and following the sampling period to ensure adequate sample volume was
collected. A vacuum will be maintained within the canisters at the conclusion of the sampling
event, and vacuum measurements which include pre- and post -sampling, and sample collection
time durations will be recorded on the chain -of -custody. Canisters that have lost greater than 10%
of their vacuum as determined by comparing the vacuum recorded by the laboratory prior to
shipment and the vacuum recorded in the field during the leak test procedures will not be used for
sampling. In addition, a vacuum of five to seven inches of mercury will be maintained on the
sample canisters until the conclusion of the sampling event.
After sample collection, the intake valve will be closed, and the regulator will be disconnected from
the sample canister. The canisters will be placed in laboratory supplied shipping containers, properly
labeled, and shipped under standard chain -of -custody protocols to SGS North America Inc. — Dayton
(SGS) for analysis of VOCs by EPA Method TO-15. Table 1 summarizes the proposed sub -slab

vapor and soil gas and associated analyses. Information pertaining to EMSL's certifications and
accreditations for mercury and SGS's certifications and accreditations for TO-15 in New Jersey
(North Carolina does not provide TO-15 certifications) is provided in Appendix A.
After completion of the soil vapor VOC sample collection, H&H will cap the points for a minimum
of least four hours prior to collection of a final round of methane, carbon dioxide, oxygen, and
pressure measurements. A total of three pressure and two gas measurements will be collected per
sample location. The interpreted stabilized/peak concentration of methane (percent by volume,
percent lower explosive level, and parts per million) for each sampling point, field notes, and
instrument logs will be provided in the Brownfields Assessment Report (discussed further in
Section 3.7).
Upon completion of vapor intrusion assessment activities, sub -slab vapor and soil gas monitoring
point locations will be recorded in the field using a hand-held GPS unit, and then properly
abandoned. Surfaces will be repaired to generally match pre -sampling conditions.
3.5 Quality Assurance/Quality Control Samples
Non -dedicated equipment and tools will be decontaminated prior to use at each boring or sampling
location or following exposure to soil, soil gas, sub -slab gas, and/or groundwater samples.
Decontamination of non -dedicated equipment will follow U.S. EPA Region IV guidance
(LSASDPROC-205-R4) and will consist of wiping the equipment clean, a water -rinse of the
equipment, washing the equipment in water and detergent (i.e., Liquinox® or Luminox®), and a
final rinse with water. The process will be repeated for grossly contaminated non -dedicated
equipment.
For quality assurance and quality control purposes (QA/QC), and to evaluate the reproducibility
of the sample results, H&H will collect the following: 1) one duplicate soil sample; 2) one
duplicate groundwater sample; and 3) one duplicate soil gas or sub -slab gas sample for VOCs.
The duplicate samples will be submitted for the same laboratory analysis as their respective parent
samples. For the duplicate soil gas/sub-slab gas sample, H&H will utilize a laboratory supplied

"T-sampler" which allows for collection of two samples from the same location simultaneously.
Per laboratory standard operating procedures, a vacuum of approximately five inches of mercury
will be maintained within all canisters at the conclusion of the sampling event. In addition, one
laboratory -provided trip blank sample will be included for every cooler/shipment containing
groundwater samples for VOC analysis.
Laboratory QA/QC procedures will be employed to ensure appropriate sample handling and
analysis and to aid in the review and validation of the analytical data. QA/QC procedures will be
conducted in accordance with the method protocols and will include regular equipment
maintenance, equipment calibrations, and adherence to specific sample custody and data
management procedures. Samples will be analyzed in conjunction with appropriate blanks,
laboratory duplicates, continuing calibration standards, surrogate standards, and matrix spiking
standards in accordance with approved methodologies to monitor both instrument and analyst
performance. Laboratory reporting limits for each analyte will be at or below appropriate
screening criteria, where possible. Additionally, H&H will request that the laboratory include
estimated concentrations for compounds that are detected at levels above the laboratory method
detection limit, but below the laboratory reporting limit (i.e., J flags).
The laboratory analytical data report and QA package for each group of samples submitted to and
analyzed by the subcontracted laboratory will be provided in an appendix to the final report.
Laboratory QA data consistent with Level II documentation will be requested for this project. A
copy of the completed chain -of -custody record and shipping receipt will be appended to the
corresponding laboratory analytical report included with the final report.
3.6 Investigation Derived Waste (IDW)
Investigation derived waste (IDW) generated during the assessment activities will be thin spread
on -Site. However, if significant impacts are suspected (i.e., high PID readings, free -product, etc.),
the soil cuttings and generated groundwater will be containerized in 55-gallon drums and staged
on -Site pending analytical results of composite IDW samples.
