present approximately 23 years which includes a small outdoor patio area on the street level.
4) Building Four, identified as 500/502 West Morgan Street, contains a 5,290 square foot
commercial building constructed in 1959 and contains Wilson's Outdoor Equipment.
The prospective developer (PD), Hennepin Ventures, LLC, submitted a Brownfields Property (BP)
Application on March 30, 2020. Subsequently, on May 18, 2020, the PD was deemed eligible to
enter the North Carolina Department of Environmental Quality (NCDEQ) Brownfields Program
(the Program) and to pursue a brownfields agreement. The proposed redevelopment plan will
include a mixed -use structure consisting of multifamily space, retail space, and associated

Peerless Master Cleaners & Dyers - Brownfields Environmental In -Situ Soil Assessment Work Plan Rev. 1.0
Brownfields Project #24020-20-092
structure parking.
ECS Southeast, LLP (ECS) and TRC Environmental Corporation (TRC) previously completed
three environmental assessment reports and one geotechnical engineering report, which included
historical environmental data research and soil, soil gas, and groundwater quality sampling and
analyses. The scope and findings of the prior assessment work includes the following:
• In 2005 during a Limited Phase II Environmental Investigation performed by TRC, two soil
quality samples, SB-1 and SB-2, and two groundwater samples, SB-1 and SB-4 were
collected for analysis.
Soil samples analyzed for Volatile Organic Compounds (VOCs) and Semi -
Volatile Organic Compounds (SVOCs) did not reveal detections; and
The groundwater sample from SIB-4 which was located outside the former paint
room of the Wilson's Outdoor Equipment building, was analyzed for VOCs and
SVOCs and detected two constituents above the NCAC 2L Groundwater Quality
Standards (NC2LGWQS or 2L) as well as another constituent that did not have
a standard. Naphthalene was detected at 26 micrograms per Liter (pg/L) and the
standard is 6 pg/L. Tetrachloroethene (PCE), a common solvent, was identified
at 2.3 pg/L and the standard is 0.7 pg/L. p-Isopropyltoluene was detected at 13
pg/L and had no 2L standard. Laboratory analysis of the groundwater sample
collected from SIB-1 did not report concentrations of analytes above their
respective 2L.
• In August 2019, ECS performed a Phase I Environmental Site Assessment (Phase 1) for
the subject site and reported several recognized environmental conditions (RECs).
In November 2019, ECS performed a Limited Phase II Environmental Site Assessment
(Phase II) for the subject site. Nine soil samples and nine groundwater samples were
collected for analysis during the Phase II. Sample locations are depicted on Figure 3.
Soil samples were analyzed for Volatile Organic Compounds (VOCs), Semi -
Volatile Organic Compounds (SVOCs), RCRA-8 Metals, and Hexavalent
Chromium (Cr VI). Laboratory analysis of several samples reported
concentrations of Cr VI, arsenic, and/or total chromium that exceeded their
respective residential and/or industrial/commercial preliminary soil remediation
goals (PSRGs).
Groundwater samples were analyzed for VOCs, SVOCs, RCRA-8 Metals, and
Cr VI. Laboratory analysis of several samples reported concentrations of PCE,
lead, barium, mercury, bis(2-ethylhexyl)phthalate, and/or total chromium that
exceeded their respective NC2LGWQS.
A series of meetings and conference calls were subsequently conducted with the Program
internally in 2020 and 2021 to review the earlier assessment findings, and to discuss additional
work needed to fill data gaps for the Brownfields agreement process. A Work Plan was developed
intended to fill those data gaps, and also included additional proposed assessment activities in
an effort to meet site specific HUD 223(f) lending requirements associated with the delineation of
tetrachloroethene (PCE) in groundwater. The identified data gaps, which were the focus of that
Work Plan, included the following:
• A potential UST, yet to be verified. if warranted, the tank may need to be properly closed
in accordance with NCDEQ UST Section guidance;
• Possible soil and/or groundwater impacts in the vicinity of former geotechnical boring B-
2

Brownfields Project #24020-20-092
5 which was reported to exhibit petroleum like odors;
• The lack of soil gas data and/or sub -slab soil gas data available at the site; and,
• Four existing monitoring wells located on the property will need to be properly abandoned
prior to their destruction during redevelopment, and only upon approval by the NCDEQ;
ECS is currently completing the assessment activities outlined in Brownfields Environmental
Assessment Work Plan (Revision Number: 2.0) for the above referenced site (Brownfields Project
#24020-20-092). Sample locations for the ongoing assessment are included in Figure 4.
The proposed scope of this Environmental In -Situ Soil Assessment Work Plan includes 40 soil
borings in 8 cells, field screening, the collection of 15 soil samples, as well as one QA/QC sample
per day of soil sampling activities conducted for North Carolina certified laboratory analysis. The
soil samples proposed in this Work Plan will be analyzed for VOCs by EPA Method 8260, for
SVOCs by EPA Method 8270, by EPA Method 6020/7471 for RCRA 8-Metals, and by EPA
Method 7199 for Cr VI, as summarized in attached Table 1. Proposed sample locations are
illustrated on Figures 5 & 6. This work has been developed in accordance with the November
2018 Brownfields Program Work Plan Checklist.
Detection limits from the laboratory will be below those set forth in the most recent version of the
PSRGs. The areas and soil boring locations are shown on Figures 5 & 6. The samples will be
collected in a celled approach and at incremental depths in order to provide a better horizontal
characterization of the soil. As depicted on Figure 5, the site has been broken into 8 individual
cells. Due to varying cut and fill depths across the site, ECS calculated the approximate amount
of soil to be cut in each area, then divided soil to be assessed into two depth intervals, 0 to 5 feet
below ground surface (bgs) and 5 feet bgs to the estimated termination depth of the excavation
in that area. The amount of soil to be assessed and corresponding sample identification have
been listed below. The overall required number of samples to be analyzed by the laboratory will
be minimized by utilizing this horizontal composite sampling method. The proposed sampling
approach results in varied frequencies and will be no less than one sample per 1,070 cubic yards
as listed and described below.
2.0 SCOPE OF WORK
The objective of this work plan is to pre -characterize site soils for re -use and disposal purposes
as requested by Hennepin Ventures, LLC and to be reviewed and approved by the Program. The
scope of sampling set forth herein, once approved by DEQ, will be sufficient to characterize soils
anticipated for export from the Brownfields property to various off -site locations as approved by
DEQ and the receiving site.
2.1 Pre -Assessment Tasks
Prior to assessment activities, ECS will contact North Carolina One Call (NC811) to identify public
underground utilities at the site. This notification requires 72 hour response time exclusive
of weekends and holidays. Our experience indicates that 811 normally does not locate private
utilities. As such, ECS will provide a private utility locator to locate subsurface utilities in proposed
soil boring locations both interior and exterior to subject site buildings to clear utilities at the
proposed boring locations.
2.2 Soil Assessment
ECS will contract with a North Carolina Certified Well Contractor (NCCWC) to perform forty (40)
soil borings advanced for the collection of soil quality samples. Figures 5 & 6 have been included
as a proposed in -situ sample boring location maps and illustrate the approximate locations of the
proposed soil borings identified as B-1 through B-40. Borings except for B-36 and B-37 will be
completed with a Direct Push Technology (DPT) drill rig provided by the North Carolina Certified

Peerless Master Cleaners & Dyers - Brownfields Environmental In -Situ Soil Assessment Work Plan Rev. 1.0
Brownfields Project #24020-20-092
Well Contractor. Borings B36 and B-37 will be advanced utilizing a decontaminated hand auger.
The borings will range from zero to 12 feet and are dependent upon the existing grade and cut
plans associated with the site's redevelopment. Borings B-13, B18, B-19, B-31, B-32, B-33, and
B-34 are located within existing structures and will require a special DPT rig and equipment in
order to accomplish boring completions to their proposed termination depths.
The exact locations of the soil borings will be determined in the field to avoid buried utilities,
although will be placed in the approximate locations illustrated on Figures 5 & 6 and advanced to
the approximate depths as summarized in Table 1. Soil borings will be abandoned by a NCCWC
upon completion of the sampling event.
2.6 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. Stephanie Graham, 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). The DPT drill rig will advance
borings from ground surface to termination depths ranging from 5 feet bgs to a maximum of 12
feet bgs. Soil samples will be collected at varying depths throughout the proposed areas under
the supervision of our field geologist. Depths sampled will be in five-foot increments and with
maximum boring termination depths varying due to existing grade and redevelopment cut plans.
ECS will remove the soil cores from the disposable PVC liners produced by the DPT drill rig,
visually classify the soil collected from each boring, and screen the soil samples for relative levels
of volatile organic vapors using a photoionization detector (PID) or similar device. If elevated
volatile organic vapor concentrations or visual/olfactory observations indicate evidence of soil
impacts, ECS will denote on the soil boring log. Borings will be abandoned by the NCCWC upon
completion in accordance with NCAC 2C standards.
The samples are to be analyzed by EPA Method 8260 for VOCs, EPA Method 8270 for SVOCs,
EPA Method 6020/7471 for RCRA 8-Metals. The six samples exhibiting the highest total
chromium concentrations will be additionally analyzed for Cr VI by EPA Method 7199 in
accordance with the attached Table 1. For VOCs, a grab sample will be collected from the boring
within each celled area which contains the highest relative levels of volatile organic vapors within
that five-foot vertical increment. VOC samples will be taken directly from the core; soil that has
been screened with the PID will be ineligible for sampling.
Following the collection of representative VOC samples, SVOCs, RCRA 8-Metals, and Cr VI
samples will be composited by gently mixing the five representative samples collected from each
celled area's similar 5 foot depth horizons which will result in a celled horizontal composite
sample. Samples will be collected into laboratory supplied/preserved containers. Following
collection they will be emplaced within an ice chilled cooler for courier transportation to the
laboratory. One (1) duplicate (non -background) soil samples are to be collected per day during
the soil assessment for Quality Assurance/Quality Control (QA/QC) purposes. The duplicate(s)
will be submitted for the same soil analyses as the sample it is duplicating (See Table 1).
M

Peerless Master Cleaners & Dyers - Brownfields Environmental In -Situ Soil Assessment Work Plan Rev. 1.0
Brownfields Project #24020-20-092
For VOCs grab samples, and for SVOCs and RCRA 8-metals composite samples will be taken
as follows:
• Cell 1 will have two (2) samples
o 131-1, representative of approximately 865 cubic yards of soil
o 131-2, representative of approximately 355 cubic yards of soil
• Cell 2 will have two (2) samples;
o 132-1, representative of approximately 1,070 cubic yards of soil
o 132-2, representative of approximately 464 cubic yards of soil
• Cell 3 will have six (2) samples;
o 133-1, representative of approximately 1,040 cubic yards of soil
o 133-2, representative of approximately 360 cubic yards of soil
• Cell 4 will have one (1) sample;
o 134-1, representative of approximately 690 cubic yards of soil
• Cell 5 will have two (2) samples;
o 135-1, representative of approximately 830 cubic yards of soil
o 135-2, representative of approximately 590 cubic yards of soil
• Cell 6 will have two (2) samples;
o 136-1, representative of approximately 840 cubic yards of soil
o 136-2, representative of approximately 230 cubic yards of soil
• Cell 7 will have two (2) samples;
o 137-1, representative of approximately 950 cubic yards of soil
o 137-2, representative of approximately 550 cubic yards of soil
• Cell 8 will have two (2) samples;
o 138-1, representative of approximately 700 cubic yards of soil
o 138-2, representative of approximately 500 cubic yards of soil
The initial horizontal composite samples will be taken from 0-5 feet bgs. Subsequent samples will
be taken from 5 feet bgs to the estimated termination depth of the excavation at that location.
Soils will be collected in approximate 1-foot increments until reaching the desired boring
termination depth. The area represented by Cell 4 will only have one composite sample due to
the estimated total amount of cut soils in this area.
Duplicate soil samples are to be collected at a rate of one duplicate sample, per medium, per
container type, per field day during the soil assessment for Quality Assurance/Quality Control
(QA/QC) purposes. The duplicates (DUP-1, DUP-2, DUP-3, etc.) will be submitted for the same
soil analyses as the sample they are duplicating (See Table 1).
3.4 Deviation from Approved Plan
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 a Hennepin Ventures, 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, followed by a hard copy or electronic copy provided on
Disk or similar media) prior to implementation. Amendments must have the approval of the
Program prior to implementation.

4.0 LABORATORY ANALYSIS
4.1 Soil Analytical
Following sample collection, the sample containers will be labeled and maintained under chain
of -custody until delivered to Eurofins Analytical Laboratory (Eurofins), a North Carolina certified
laboratory located in Savanna, Georgia. Eurofins currently holds NC Lab Certification #269. A
Chain -of Custody document will be utilized throughout the collection and transportation of the
samples. The fifteen (15) soil quality samples (not inclusive of duplicates) collected from the forty
(40) proposed boring locations will be analyzed for VOCs by EPA Method 8260, SVOCs by EPA
Method 8270, RCRA 8-metals by EPA Methods 6020/7471, and Cr VI by EPA Method 7199 (six
samples with highest total chromium concentration).
Duplicate (QA/QC) soil samples will also be collected into laboratory supplied/preserved containers.
The samples will be submitted for analysis of VOCs by EPA Method 8260, SVOCs by EPA Method
8270, EPA Method 6020/7471 for RCRA 8-Metals, and Cr VI by EPA Method 7199 (where
applicable).
Field screening will be conducted with a PID or similar device. The ECS environmental
professional will observe the soil, note its color and texture, and document if the soil exhibits
staining or exudes distinguishable odors. Representative samples are to be collected as a
composite for SVOCs, RCRA 8-metals, and Cr VI (where applicable), and directly from the
macrocore registering the highest levels of VOCs on the PID. The laboratory's Reporting Limits
(RLs) and/or Method Detection Limits (MDLs) will be reported at or below Residential Preliminary
Soil Remediation Goals (PSRGs) (to the extent feasible) and J Flags (laboratory estimated
concentrations) will be reported. A Level II QA/QC package will be reported by the laboratory.
5.0 QA/QC
5.1 Soil Samples
Duplicate soil samples are to be collected at a rate of one duplicate sample, per medium, per
container type, per field day during the soil assessment for QA/QC purposes. If more than 20
samples are collected in a day, additional duplicate samples will be collected. The duplicates
(DUP-1, DUP-2, DUP-3, etc.) will be submitted for the same soil analyses as the sample they are
duplicating (See Table 1).
Following sample collection, the sample containers will be labeled and maintained under chain -
of -custody until delivered to Eurofins in Savanna, Georgia by local courier. 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.
IDW will be containerized onsite pending receipt of laboratory analytical results and will be
subsequently managed in accordance with Section B.5 Investigation -Derived Waste of the NCDEQ,
Inactive Hazardous Sites Program Guidelines for Assessment and Cleanup of Contaminated Sites
(July 2021).

Notes:
VOCs will be collected as a grab sample directly from the macrocore of the boring/horizon with the highest PID reading
SVOCs and Metals will be collected as composite samples
Refer to Figure 4 for proposed sample locations
*Duplicate samples will, if applicable, be collected at depth intervals that are found to be impacted during field work.
The six samples exhibiting the highest total chromium concentrations will be additionally analyzed for Cr VI by EPA Method 7199.
