SMARTER ENVIRONMENTAL SOLUTIONS
Following up on your October 1, 2018 request, on behalf of the Prospective Developer or PD
(LRC VII LLC), Hart & Hickman, PC (H&H) has prepared this Work Plan to conduct
Brownfields assessment activities for the Brownfields property located on Watkins Road in
Durham, Durham County, North Carolina (subject Site or Site). The subject Site totals
approximately 8.0 acres on two parcels of land located in a mixed light industrial and
commercial area of Durham. The PD sold 3.7 acres of the Brownfields Site (i.e., the western
parcel) to Crowne at 501, Limited Partnership (hereinafter referred to as the Witherspoon
Nursery West property), and the PD retained the eastern 4.3 acres of the Brownfields Site
(hereinafter referred to as the Witherspoon Nursery East Property). A Site location map is
provided as Figure 1, and a Site map is included as Figure 2.
The Witherspoon Nursery East property (3330 Watkins Road; Durham County Parcel
Identification No. [PIN] 080021836190) is improved with multiple structures previously used for

administration and storage related to historical plant nursery operations. A residential -type
structure was constructed in the mid-1950s in the northeastern portion of the Site and used for
administrative purposes. Other Site structures were constructed in various stages from the 1970s
through 1980s and are predominately situated in the central and southeastern portions of the
Witherspoon Nursery East property. In addition, an approximately 8,000 square foot (sq ft)
irrigation pond is near the eastern property boundary.
The Witherspoon Nursery West property (3312 Watkins Road; Durham County PIN
080021633681) is improved with an approximately 1,450 sq ft residential -type building located
in the northwest portion of the Site. The building was reportedly constructed in the early 1960s
and then used for administrative purposes. Remaining portions of the Witherspoon Nursery
West property include former greenhouse structures, gardens, gravel parking, and vegetated
areas.
H&H reviewed available resources to obtain information regarding the historical uses of the Site
and identify areas of potential environmental concern for Brownfields assessment. A brief
summary of our review is provided in the following section.
2.0 Background
From the mid- 1970s until the mid-201Os, Witherspoon Rose Culture Inc. conducted plant nursery
operations at the Site. These operations included selling gardening supplies, cultivation of
plants, and storage of agricultural products that contained pesticides and herbicides. From
November 2015 through March 2018, several investigations were conducted by ATC Associates
of North Carolina, P.C. (ATC) and Terracon Consultants, Inc. (Terracon) to assess areas of
potential environmental concerns related to these operations. A Site map referencing features
identified during the investigations is included as Figure 2. A brief discussion of previous
assessment activities completed at the Site is provided in the following sections.

2.1 ATC 2015 Assessment Activities
In November 2015, ATC completed soil, groundwater, and sump assessment at the subject Site.
The assessment activities were documented in a December 11, 2015 Limited Phase II
Environmental Site Assessment report. The sampling was conducted to investigate areas of
potential environmental concern identified during a previous ATC Phase I Environmental Site
Assessment (ESA).
As part of the field activities, eight (8) borings were advanced via hollow stem auger in various
locations throughout the subject Site. The borings were advanced to depths ranging from 7.5 to
25 ft below ground surface (bgs) and soils were collected from a hand auger or standard
penetration test (SPT) sampler and later screened with a photoionization detector (PID).
In addition to the soil assessment, water samples were collected from two water supply wells
located in the northeastern and northwestern portions of the Site, two sumps located in the central
and south-central portions of the Site, and two temporary monitoring wells in the south-central
and southeastern portions of the Site. The temporary monitoring wells were installed to a depth
of 25 ft bgs and groundwater was only encountered in one of the temporary wells (south-central
portion of the Site) at an approximate depth of 4.5 ft bgs. According to the report, the water
supply well, sump, and temporary monitoring well samples were analyzed for organochlorine
pesticides and chlorinated herbicides. The laboratory analytical report indicates that the samples
were also analyzed for polychlorinated biphenyls (PCBs). The analytical results did not indicate
detections of pesticides, herbicides, or PCBs in the water samples above laboratory reporting
limits.
2.2 Terracon 2017 Assessment Activities
In September 2017, Terracon completed soil assessment at the Witherspoon Nursery West
property. The assessment activities were documented in an October 11, 2017 Limited Site

Investigation report and conducted to investigate areas of potential environmental concern
identified during a previous Terracon Phase I ESA.
As part of the field activities, composite soil sampling was targeted to seven areas based on
historical plant nursery operations. In addition to the composite soil sampling, grab soil
sampling was also conducted to investigate impacts related to a heating oil aboveground storage
tank (AST) in the northwestern portion of the Site and a former septic drain field in the
southwestern portion of the Site. The composite samples were collected from the ground surface
to depths of approximately 6 ft bgs and submitted for laboratory analysis of organochlorine and
organophosphorus pesticides, chlorinated herbicides, and the metals arsenic, copper, and lead.
The grab samples were collected from depths of approximately 1 to 4 ft bgs and submitted for
laboratory analysis of gasoline -range and diesel -range total petroleum hydrocarbons (TPH-GRO
and TPH-DRO).
The laboratory analytical results indicated arsenic was detected at concentrations ranging from
0.79 to 26 milligrams per kilogram (mg/kg) in each of the composite and grab samples analyzed.
These concentrations exceed the North Carolina Department of Environmental Quality (DEQ)
Residential, Industrial/Commercial, and/or Protection of Groundwater Preliminary Soil
Remediation Goals (PSRGs). Arsenic is a naturally occurring inorganic compound and can be
found in North Carolina soils at concentrations similar to the aforementioned levels (see
Elements in North American Soils by Dragun and Chekiri, 2005).
Composite samples collected from former gardening areas in the north -central and central
portions of the Site and former septic drain field in the southwestern portion of the Site indicated
low levels of pesticides in soils. Organochlorine pesticides aldrin, gamma-BHC, alpha-BHC,
and heptachlor epoxide were detected above their respective Protection of Groundwater PSRGs
but below Residential and Industrial/Commercial PSRGs.

Grab sampling conducted in the vicinity of the heating oil AST in the northwestern portion of the
Site indicated impacted soils. DRO was detected at a concentration (270 mg/kg) that exceeds the
DEQ Action Level of 100 mg/kg.
2.3 ATC 2018 Assessment Activities
Based on the results of Terracon's 2017 soil assessment, ATC oversaw removal and excavation
activities of two former diesel ASTs (AST-1 and AST-2) on the Witherspoon Nursery East
property and one former heating oil AST (AST-3) on the Witherspoon Nursery West property.
Removal of the ASTs was conducted in March 2018 and documented in the March 28, 2018 and
May 1, 2018 Soil Excavation Activities — Witherspoon Roses Property reports prepared by ATC.
During removal activities, approximately 5.95 and 6 tons of petroleum impacted soil were
excavated from soils in the vicinity of AST-1 and AST-3, respectively. Confirmatory soil
samples were then collected from each excavation area for analysis of volatile organic
compounds (VOCs) and semi -volatile organic compounds (SVOCs). One additional soil sample
was also collected from the AST-3 excavation and analyzed for TPH-GRO and TPH-DRO and
Toxicity Characteristic Leaching Procedure (TCLP) metals (for disposal purposes). The results
of the soil sampling did not indicate exceedances of Soil -to -Groundwater Maximum Soil
Contaminant Concentrations (MSCCs).
The Site received eligibility into the DEQ Brownfields Program (Brownfields Project No. 22004-
18-032) via a Letter of Eligibility dated April 26, 2018. On October 1, 2018, The Brownfields
Project Manager requested additional assessment to evaluate risk -assessment based options for
the proposed redevelopment of the Site. On October 10, 2018, H&H participated in a conference
call with DEQ Brownfields personnel to discuss proposed redevelopment plans for the Site,
potential data gaps, and the scope of Brownfields assessment activities needed to address the data
gaps for development of an Environmental Management Plan (EMP). Based on DEQ's
requirements defined during the conference call, H&H proposes to conduct soil, groundwater,
and irrigation pond assessment activities to evaluate subsurface conditions for potential impacts

in certain areas of the property. Proposed Brownfields assessment activities are outlined in the
following sections.
During the October 10, 2018 conference call, DEQ noted that two arsenic detections of 23 mg/kg
and 26 mg/kg in soil may be elevated. However, DEQ stated that they are below internally used
DEQ screening levels for residential properties.
3.0 Brownfields Assessment Activities
H&H proposes to conduct soil, groundwater, and irrigation pond assessment activities at the Site
to evaluate the potential for impacts associated with historical Site uses and to assist in
development of an EMP for use during planned redevelopment of the Site. Specifically,
groundwater and irrigation pond assessment activities will be conducted on the Witherspoon
Nursery East property and soil and groundwater assessment activities will be conducted on the
Witherspoon Nursery West property. The proposed assessment activities will be performed in
general accordance with DEQ's Inactive Hazardous Sites Branch (IHSB) Guidelines for
Assessment and Cleanup (Guidelines) dated October 2015 and most recent versions of the U.S.
Environmental Protection Agency (EPA) Region IV Science and Ecosystem Support Division
(SESD) 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 team with a private
utility locator to identify and mark locations of sub -grade utilities at the Site that would not be
marked by the public locator. In addition, prior to boring advancement, a hand auger will be
advanced to a depth of approximately 5 ft bgs at the proposed boring locations to further clear for
potential subsurface utilities.

3.1 Soil Assessment Activities
H&H proposes to conduct soil assessment activities at the Witherspoon Nursery West property to
evaluate current subsurface conditions for potential impacts. H&H will team with a qualified
drilling contractor to advance two (2) soil borings to depths ranging from approximately 5 to 25
ft bgs (or refusal). Specifically, the borings will be advanced in the former septic drain field in
the southwestern portion of the Site (SB-1) and the former septic drain field south of the
administrative building (SB-2) in the west -central portion of the Site. Proposed soil sample
locations (denoted by SB nomenclature) are depicted on the sample location map, which is
presented as Figure 3.
The soil borings will be advanced utilizing a track -mounted direct push technology (DPT) drill
rig. Continuous soil samples will be collected from the borings using acetate lined macrocore
sleeves. Soil samples will be logged for lithological description and field screened for indication
of potential impacts by observation for staining, and the presence of organic vapors using a
calibrated PID. Based upon field screening results, one soil sample will be collected from each
soil boring for laboratory analysis from the depth interval interpreted most likely to be impacted.
If there are no obvious indications of potential impact based on field screening results, then a
sample will be collected from shallow soil potentially below the depth of the leach field
(estimated to be 3 to 5 ft bgs).
Following collection, 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. Soil samples will be submitted to a North Carolina certified
laboratory under standard chain of custody protocols for analysis of VOCs by EPA Method 8260
and SVOCs by EPA Method 8270. In addition, the soil sample collected south of the former
administrative building will also be submitted for analysis of Resource Conservation and
Recovery Act (RCRA) metals plus hexavalent chromium by EPA Methods 6020/7471/7196.

Laboratory analyses for proposed soil sampling to be conducted on the Witherspoon Nursery
West property is referenced in Table 1.
Following sampling activities, borings will be properly abandoned and the surfaces will be
repaired similar to pre -drilling conditions. Additionally, soil sample locations will be estimated
using a hand-held global positioning system (GPS) unit.
3.2 Groundwater Assessment Activities
H&H will instruct the drilling contractor to utilize the DPT drill rig (equipped with an air
hammer) to advance borings for installation of one (1) temporary groundwater monitoring well
on Witherspoon Nursery East property and three (3) temporary groundwater monitoring wells on
Witherspoon Nursery West property. The air hammer will be used due to the reported presence
of weathered siltstone at shallow depths at this Site. Based on the October 2018 conference call
with DEQ, borings for the temporary wells will be terminated at 25 ft bgs if groundwater is not
encountered. The approximate locations of the proposed temporary monitoring wells (denoted
by TMW nomenclature) are shown on the sample location map, which is presented as Figure 3,
and are described below:
• downgradient of the sumps in the central and south-central portions of the Witherspoon
Nursery East property (TMW-1);
• downgradient of the former septic drain field in the southern portion of the Witherspoon
Nursery West property and near the former boring B-05 where groundwater was
encountered (TMW-2);
• near the former septic drain field south of the administrative building in the west -central
portion of the Witherspoon Nursery West property (TMW-3); and
• near the former heating oil AST south of administrative building in the northwestern
portion of the Witherspoon Nursery West property (TMW-4).

During drilling, soil samples will be collected and logged for lithologic description and field
screened for presence of staining and elevated concentrations of volatile organic vapors using a
PID. The temporary monitoring wells will be constructed of 2-inch diameter PVC with 15 ft of
well screen set to bracket the water table and 2-inch diameter PVC well casing to the ground
surface. A sand filter pack will extend from below the base to approximately 2 ft above the top
of the well screens. The temporary wells will be completed by placing a hydrated bentonite seal
from the top of the sand filter pack to the ground surface. Once the temporary monitoring wells
are installed, the wells will be allowed to equilibrate to static conditions overnight, and a
decontaminated electronic water level indicator will be used to measure the depth to the water
table relative to the ground surface.
The wells will then be developed by removing a minimum of 3 to 5 well volumes and observing
stable field parameters (i.e. pH f 0.1 SU and conductivity varies no more than 5%). After
development, a groundwater sample will be collected utilizing low flow/low stress purging
techniques using a peristaltic pump and dedicated polyethylene tubing. 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
utilize 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).
Once groundwater parameters stabilize, groundwater samples will be collected directly into
laboratory supplied sample containers using the "soda straw" method to eliminate the potential
for volatile loss through the peristaltic pump head. The sample containers will be labeled with
the sample identification, date, and requested analysis, and placed in a laboratory supplied cooler
and iced. The samples will be delivered to a North Carolina certified laboratory under standard
chain of custody protocols for analysis of VOCs by EPA Method 8260 and SVOCs by EPA
Method 8270. Laboratory analyses for proposed groundwater sampling conducted on the

Witherspoon Nursery West and Witherspoon Nursery East properties are referenced in Tables 1
and 2, respectively.
Upon completion of groundwater sampling activities, temporary monitoring wells will be
properly abandoned by a licensed well driller and surfaces will be repaired to generally match
pre -drilling conditions. Soil and groundwater sample locations will be recorded in the field using
a hand-held GPS unit.
3.3 Irrigation Pond Assessment Activities
H&H proposes to collect two (2) co -located surface water and sediment samples for laboratory
analysis from the irrigation pond located on Witherspoon Nursery East property. Co -located
surface water and sediment sample locations (denoted by SW/SED nomenclature) are shown on
Figure 3. H&H will utilize water quality meters to collect measurements of pH, temperature,
dissolved oxygen, oxidation reduction potential, turbidity, and specific conductivity of surface
water at each sample location. Sediment samples will be collected from the base of the irrigation
pond at each sample location using a decontaminated stainless steel AMS dredge sampler or
other suitable method.
Surface water and sediment samples will be collected directly into laboratory -supplied sample
containers. The sample containers will be labeled with the sample identification, date, and
requested analysis, and placed in a laboratory supplied cooler and iced. The surface water and
sediment samples will be delivered to a North Carolina certified laboratory under standard chain
of custody protocols for analysis of VOCs by EPA Method 8260, SVOCs by EPA Method 8270,
RCRA metals plus hexavalent chromium by EPA Methods 6020/7471/7196, organochlorine
pesticides by EPA Method 8081, organophosphorus pesticides by EPA Method 8141, and
herbicides by EPA Method 8151. In addition to total RCRA metals, surface water samples will
also be analyzed for dissolved RCRA metals plus hexavalent chromium by EPA Methods
6020/7471/7196, as well as nitrate by EPA Method 353.2. Laboratory analyses for proposed

surface water and sediment sampling conducted on the Witherspoon Nursery East property are
referenced in Table 2.
Upon completion of sampling, the co -located surface water and sediment sample locations will
be estimated using a hand-held GPS unit.
3.4 Quality Assurance/Quality Control Samples
Laboratory quality assurance/quality control (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 EPA method protocols and will
include regular equipment maintenance, equipment calibrations, and adherence to specific
sample custody and data management procedures. In accordance with approved methodologies,
samples will be analyzed in conjunction with appropriate blanks, laboratory duplicates,
continuing calibration standards, and surrogate standards to monitor both instrument and analyst
performance. H&H will request that the laboratory reporting limits for each analyte will be at or
below appropriate screening criteria. Additionally, H&H will request that the laboratory include
J Flags, which are estimated concentrations for compounds that are detected at levels above the
laboratory method detection limits, but below the laboratory reporting limits.
The following activities will be conducted by H&H for QA/QC purposes:
• non -dedicated equipment and tools will be decontaminated prior to use at each boring or
sampling location, or following exposure to soil or groundwater;
• one duplicate soil sample will be analyzed for VOCs by EPA Method 8260, SVOCs by
EPA Method 8270, RCRA metals plus hexavalent chromium by EPA Methods
6020/7471 /7196;
• one duplicate groundwater sample will be analyzed for VOCs by EPA Method 8260 and
SVOCs by EPA Method 8270; and

• one trip blank will accompany samples during field and shipping activities. The trip
blank will be analyzed for VOCs by EPA Method 8260.
Laboratory analyses for proposed QA/QC sampling is referenced in Table 1. A copy of 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 will be appended to the corresponding laboratory
analytical report included with the final report.
3.5 Investigation Derived Waste
Investigation derived waste (IDW) generated during the assessment activities will be thin spread
on -Site. However, if significant impacts are suspected, the soil cuttings will be containerized in
55-gallon drums and staged on -Site pending analytical results of a composite IDW sample.
Based on laboratory analytical results of IDW samples, the drums will be transported off -Site to a
suitable facility for disposal.
3.6 Reporting
Following completion of the assessment activities and receipt of the analytical data, H&H will
document our findings in a Brownfields assessment report. The report will include a description
of the sampling activities, a figure depicting sample locations, soil boring and well construction
logs, laboratory analytical data, a discussion of the data in comparison to regulatory screening
levels, IDW manifests (if applicable), and conclusions and recommendations concerning our
activities.
