Wright's Executive Sales 11 — Import Soil Sampling Work Plan Rev. 2.0
Brownfields Project No. 24007-20-032
1.0 INTRODUCTION
The subject brownfields site (Brownfields Project Number 24007-20-032), known as Wright's
Executive Sales 11, currently consists of two parcels and a total of 2.371 acres of land (see Figures
1 and 2). It is in a commercial area of Durham just to the south of W. Geer St. and west of Foster
St. The Subject Site was occupied by three buildings associated with Acme Plumbing and Heating
offices and storage, a stand-alone yoga studio, Motorco Music Hall, and The Mothership, which
was a creative space to share, make, and collaborate on artistic projects. The Subject Site is
currently identified by the Durham County Online GIS Database with the following Parcel
Identification Numbers (PINs) and street addresses:
620 Foster St. 0822-90-31-8262; 1.91 acres
616 Foster St. 0821-99-29-7413; 0.461 acres
The property is currently planned to be redeveloped with a mixed multi -family residential,
commercial/retail, and/or restaurant complex. In order to accomplish redevelopment, it has been
estimated that the brownfields site will require an estimated additional 1,200 cubic yards of
imported fill material, with an estimated 1,400 cubic yards of imported fill material already imported
and placed onsite and utilized as utility trench/corridor backfill.
Correspondence with the North Carolina Department of Environmental Quality (NCDEQ)
Brownfields Program (the Program) on April 13, 2022 has indicated that a total of three (3)
representative composite soil characterization samples will be required to be collected from the
borrow source to support the additional import of an estimated 1,200 cubic yards. This approach
will satisfy the April 19, 2021 Program approved Environmental Management Plan (EMP) required
sampling frequency of one representative composite sample per every approximate 500 cubic
yards. Further, four (4) representative composite soil characterization samples are required to be
collected from the four sections of utility trenches/corridors where an approximate 1,400 cubic
yards of imported soil has already been placed prior to Program approval. The soil samples are
to be collected as 5-point representative composite samples.
Additionally, further Program correspondence on May 13, 2022, requested five (5) background
soil samples to be collected on the subject site and analyzed for pesticides and herbicides in an
effort to determine if the risk has increased due to the already imported soils to the subject
property. The background pesticide/herbicide soil samples will be collected as grab samples in
accordance with Section B.4 of the NCDEQ, Inactive Hazardous Sites Program Guidelines for
Assessment and Cleanup (July 2021).
The following scope of work has been developed in an effort to satisfy the import soil assessment
activities to be performed as required by the April 19, 2021 Program approved EMP. The data
obtained from executing this work plan is intended for regulatory use by the Brownfields Program
only.
2.0 SCOPE OF WORK
Per the approved EMP and per the above referenced April 13, 2022 correspondence, testing is
to be conducted for Volatiles by EPA Method 8260, Semi-volatiles by EPA Method 8270,
organochlorine pesticides by EPA Method 8081, organophosphorous pesticides by EPA Method
8141, herbicides by EPA Method 8151, Resource Conservation and Recovery Act (RCRA) 8-
Metals by EPA Method 6010, and for hexavalent chromium by EPA Method 7199. Due to
uncharacterized borrow source material already imported to the site, and the apparent historic
agricultural land use of the borrow source, this Work Plan also includes analysis of the soil for
organochlorine pesticides by EPA Method 8081, organophosphorous pesticides by EPA Method
8141, herbicides by EPA Method 8151. A total of twelve (12) samples will be collected for North

Wright's Executive Sales 11 — Import Soil Sampling Work Plan Rev. 2.0
Brownfields Project No. 24007-20-032
Carolina certified laboratory analysis. Three (3) from the area of the borrow source where
additional soil is slated to be sourced for import to the site, and four (4) from the utility
trenches/corridors where imported soil has already been placed. Additionally, five (5) background
soil grab samples will be collected on the subject brownfields property and analyzed for
organochlorine pesticides by EPA Method 8081, organophosphorous pesticides by EPA Method
8141, herbicides by EPA Method 8151.
The objective of this work plan is to maintain the liability protections offered by the Program by
characterizing the soil quality prior to it being imported to the site. The borrow source property to
be sampled is an approximate 1-acre property located at 7315 Lebanon Road in Mebane, North
Carolina as illustrated on Figure 3, and the approximate location of the imported soils already
placed on the brownfields site has been illustrated on Figure 4.
The borrow source property is reportedly undergoing residential redevelopment. A review of
historical aerial photography on Google Earth indicates that the borrow source property was used
for agricultural purposes from at least December 1985 through April 1998. By October 2005 the
property appears to be undeveloped wooded land, and it maintains this land use through at least
April 2021. Land use prior to 1985 is unknown; however, is likely to have been undeveloped
wooded land and/or used for agricultural purposes. No additional information on prior land use
history was able to be obtained for inclusion in this Work Plan.
2.1 Soil Assessment
ECS will provide an environmental professional to perform the soil sampling activities. Soil
sampling will occur from representative areas of the borrow source as well as from each of the
four (4) areas of utility trenches/corridors where imported soil was previously placed at the site.
The soil at the borrow source property is currently stockpiled, and the three (3) 5-point
representative composite soil samples will be collected from the stockpile where the import is to
be sourced from. The stockpile will be flagged off in approximate 500 cubic yard cells, and
subsequently one 5-point representative composite soil sample will be collected from each cell.
Five (5) background samples will be collected at the subject site in an effort to determine if the
risk has increased due the already imported soils to the subject property.
Soils already imported to the site will be collected with the use of a stainless -steel hand auger
and soils collected from stockpiled soils on the borrow source property will be collected utilizing a
shovel. The hand auger and shovel will be decontaminated upon arrival at each respective site,
between each representative composite soil sample area, and prior to departure from the site.
Decontamination will be conducted with scrub bushes and a municipal water/Alconox mix,
followed by a municipal water rinse. Proposed soil sample depths and additional descriptions are
included in Table 1.
2.2 Reporting
A report of the results of the sampling outlined in this work plan will be submitted to the Program.
If unidentified and unexpected conditions are encountered during the assessment, we will
consult with the Program. Holly Samaha-Smith, the Brownfields Project Manager, will be
notified 5 days prior to starting the field work.

3.0 SAMPLING METHODOLOGY
3.1 Soil Sample Collection
Soil sampling will be conducted in general accordance with the NCDEQ, Inactive Hazardous Sites
Program Guidelines for Assessment and Cleanup (July 2021). Soil characterization sample
collection will occur from representative areas of the borrow source as well as from each of the four
areas of utility trenches/corridors where imported soil was previously placed at the site. Background
soil sampling for pesticides/herbicides only will be conducted in accordance with Section BA of the
NCDEQ Inactive Hazardous Sites Program Guidelines for Assessment and Cleanup (July 2021)
from roughly the same depths of the samples collected from the utility trenches where fill soil was
previously placed.
The soil at the borrow source property is currently stockpiled, and the three 5-point representative
composite soil samples will be collected from the stockpile where the import is to be sourced from.
The stockpile will be flagged off in approximate 500 cubic yard cells, and subsequently one 5-point
representative composite soil sample will be collected from each cell.
Soils already imported to the site will be collected with the use of a stainless -steel hand auger and
soils collected from stockpiled soils on the borrow source property will be collected utilizing a shovel.
The hand auger and shovel will be decontaminated upon arrival at each respective site, between
each representative composite soil sample area, and prior to departure from the site (See Table 1).
Decontamination will be conducted with scrub bushes and a municipal water/Alconox mix, followed
by a municipal water rinse.
The ECS environmental professional will examine the soil and note the color and texture of the soil
and if the soil exhibits staining or exudes distinguishable odors. Representative samples are to be
collected from the top 5 foot depth interval exhibiting greatest field screened volatile organic vapor
concentration. If no volatile organic vapors are detected within the top 5 feet, then a representative
sample will be collected from the upper 2-feet of the boring. Please refer to Table 1 for additional
details including specific borings and proposed collection depths.
In accordance with the attached Table 1, the representative composite samples will be comprised
of five individual grab soil samples collected in duplicate re -sealable bags. One of the two duplicate
aliquots will be screened using a photoionization detector (PID) for volatile vapors and will be
ineligible for sampling. The individual grab soil sample with the highest PID reading, from the
unopened re -sealable bag will be appropriately packaged and submitted to a North Carolina certified
laboratory to be analyzed for VOCs using EPA Method 8260. Subsequently, it will be mixed with the
other four aliquots and one representative composite soil sample will be containerized for North
Carolina certified laboratory analysis by EPA Method 8270 for SVOCs, total RCRA 8-metals using
EPA Method 6010, hexavalent chromium by EPA Method 7199, organochlorine pesticides by EPA
Method 8081, organophosphorous pesticides by EPA Method 8141, herbicides by EPA Method
8151. The five background soil samples will be collected into laboratory supplied/preserved
containers and submitted for the above listed analyses for pesticides and herbicides.
Two duplicate (non -background) soil samples are to be collected during the soil assessment for
Quality Assurance/Quality Control (QA/QC) purposes. One will be collected during assessment
of the borrow source's stockpile, and one will be collected from utility trenches/corridors where
imported soil was previously placed at the site. The duplicates, identified as DUP-1 and DUP-2,
will be submitted for the same soil analyses as listed above (See Table 1).
3.2 Deviation from Approved Plan

Wright's Executive Sales 11 — Import Soil Sampling Work Plan Rev. 2.0
Brownfields Project No. 24007-20-032
This work plan is intended to be dynamic and to be adapted to specific and actual site conditions.
Accordingly, should such conditions warrant a change either by addition, deletion, or modification
of a procedure, such may be accomplished with agreement between GeerHouse Owner, LLC
representative and ECS after consultation with, and subject to approval by the Program. Such
changes will comply with applicable local, State, and Federal rules and regulations. A written
amendment shall be prepared and submitted to the Program for approval (the use of e-mail
correspondence shall suffice for approval). Amendments must have the approval of the Program
prior to implementation.
4.0 LABORATORY ANALYSIS
4.1 Soil Analytical
Following soil sample collection, the sample containers will be labeled and maintained under
chain -of -custody until delivered to Eurofins, a North Carolina certified laboratory located in
Savannah, Georgia (NC Certification No. 269) for analysis. A Chain -of -Custody document will be
utilized throughout the collection and transportation of the samples. The seven (7) composite soil
samples will be analyzed for VOCs by EPA Method 8260, SVOCs by EPA Method 8270, RCRA 8-
metals by EPA Methods 6020/7471, Cr VI by EPA Method 7199, organochlorine pesticides by EPA
Method 8081, organophosphorous pesticides by EPA Method 8141, and for herbicides by EPA
Method 8151. The five (5) background soil samples will be collected into laboratory
supplied/preserved containers and submitted for analysis of organochlorine pesticides by EPA
Method 8081, organophosphorous pesticides by EPA Method 8141, and for herbicides by EPA
Method 8151.
The two duplicate soil samples will also be collected into laboratory supplied/preserved containers
and submitted for analysis of VOCs by EPA Method 8260, SVOCs by EPA Method 8270,
organochlorine pesticides by EPA Method 8081, organophosphorous pesticides by EPA Method
8141, for herbicides by EPA Method 8151, EPA Method 6020/7471 for RCRA 8-Metals, and Cr VI
by EPA Method 7199.
The laboratory's Reporting Limits (RLs) and/or Method Detection Limits (MDLs) will be reported at
or below Residential and Industrial/Commercial Preliminary Soil Remediation Goals (PSRGs) (to the
extent feasible) and J Flags (laboratory estimated concentrations) will be reported. A Level I I QA/QC
package will be reported by the laboratory.
5.0 QA/QC
5.1 Soil Samples
Two duplicate soil samples will be collected in laboratory supplied/preserved containers and
submitted for analysis of VOCs by EPA Method 8260, SVOCs by EPA Method 8270, organochlorine
pesticides by EPA Method 8081, organophosphorous pesticides by EPA Method 8141, and for
herbicides by EPA Method 8151, EPA Method 6020/7471 for RCRA 8-Metals, and Cr VI by EPA
Method 7199. Sufficient sample volume will be collected in order for the laboratory to run MS/MSD
analysis. Following sample collection, the sample containers will be labeled and maintained under
chain -of -custody until delivered to the North Carolina certified laboratory. A Chain -of -Custody
document will be utilized throughout the collection and transportation of the samples.
6.0 INVESTIGATION DERIVED WASTE MANAGEMENT
The investigative derived waste (IDW) expected to be generated includes soil from the soil borings
and soil sampling activities. Soil IDW will be placed back down its respective borehole at the same
approximate depth it was recovered from. Excess soil, if applicable will be spread at the surface near
the borehole from which it derived.
