NORTH CAROLINA BROWNFIELDS REDEVELOPMENT SECTION
ENVIRONMENTAL MANAGEMENT PLAN
This form is to be used to prepare an Environmental Management Plan (EMP) for projects in
the North Carolina Brownfields Redevelopment Section at the direction of a Brownfields
project manager.
The EMP is a standard requirement of a Brownfields Agreement (BFA). Its purpose is to clarify
actions to be taken during demolition and construction at Brownfields properties in an effort
to avoid delays in the event of the discovery of new contamination sources or other
environmental conditions. The EMP provides a means to document redevelopment plans and
environmental data for each applicable environmental medium to inform regulatory-compliant
decision-making at the site. As much detail as possible should be included in the EMP,
including contingency planning for unknowns. Consult your project manager if you have
questions.
Prospective Developers and/or their consultants must complete and submit this form and all
pertinent attachments, see checklist below, to their Brownfields project manager prior to any
earthmoving or other development-related activities that have the potential to disturb soil at
the Brownfields Property, including demolition. For the EMP to be valid for use, it must be
completed, reviewed by the Section, signed by all parties working on the project, and
approved by the Brownfields project manager. Failure to comply with the requirements of the
EMP could jeopardize project eligibility, or in the event of a recorded agreement, be cause for
a reopener.
The EMP is valid only for the scope of work described herein and must be updated to be
applicable for new phases of redevelopment or after significant changes in applicable
regulatory guidance. Risk characterization of a Brownfields Property to DEQ’s written
satisfaction is required prior to EMP approval.
Voluntary Metrics Tab
The NC Brownfields Redevelopment Section updates estimated capital investment (from the
Brownfields Property Application) and estimated jobs created (from the Brownfields
Agreement) whenever possible. As a voluntary measure, you may opt to complete the below

from the Carolina Medical Electronics site located at 157 & 169 Industrial Drive, King, NC (Brownfields
Project No. 16017-12-085) to the proposed 450 Polo Road development. The approval was granted
12
EMP Version 3, March 2023
by NCBRS in correspondence dated August 3, 2023. S&ME notes that soils from the Carolina Medical
Electronics will be placed beneath planned impervious surfacing (buildings, parking lots areas, etc.). If
additional sources are identified after NCBRS approval of this EMP, the PD and S&ME will submit a Soil
Import Request for NCBRS’ review and approval.
Additionally, Figure 9 identifies the approximate area of shallow soils from the northern portion of the
site that will be relocated to the southern portion of the development, to be eventually “capped” with
imported fill, stone/gravel material and/or impervious surfacing.
S&ME has included a Final Grade Sampling and Analysis Plan for NCBRS’ review and approval in
Appendix VI.
☒ Confer with NC BF project manager if Brownfield Plat must be revised (or re-recorded if
actions are Post-Recordation).
☐ GPS the location and provide site map with final location.
☐ Other. Please provide a description of the measure:
4) Please describe the following action(s) to be taken during and following excavation and
management of site soils:
☒ Check to confirm that management of fugitive dust from site activities will be handled in
accordance with applicable local, state, and federal requirements.
Field screening of site soil
At a minimum, contractors shall be made aware of protocols should impacted soils (e.g. staining,
unusual odors, fill materials) be identified.
Describe the field screening method, frequency of field screening, person conducting field
screening:
As part of the review of the EMP approved by NCBRS, the General Contractor (GC) will be
made aware of the typical visual and/or olfactory evidence that is associated with
potentially contaminated soils (e.g., staining, odors, solid waste, etc.), including screening
of soils with a photoionization detector (PID).
If an unknown area of concern is encountered, redevelopment activities in the area will be
suspended. The construction company will immediately notify S&ME and the PD.
A qualified environmental professional from S&ME will assess the area, evaluate the waste
materials and/or impacted media in the area, if present, and determine the proper means
for managing these materials. Within 48 hours, S&ME will inform NCBRS of the findings
and subsequent actions to be taken for managing these materials.

EMP Version 3, March 2023
Soil sample collection
☒ Yes
☐ Not anticipated - In order to avoid delays in construction, a plan shall be in place for sampling
of suspect soils should they be encountered during redevelopment. If soil sample collection is
not anticipated but the need to do so is identified during redevelopment, notify the Brownfields
project manager of the anticipated sample and report dates for scheduling purposes.
Describe the sampling method (e.g., in-situ grab, composite, stockpile, etc.) and confirm that all
procedures outlined in applicable DEQ guidance for assessment shall be followed Typically, at
least one representative sample (per 500 yd3 for residential and 1,000 yd3 for commercial)
consisting of a 3 to 5-point composite sample with grab sample for VOCs based on the highest PID
reading is required to determine soil management options:
In the event of the discovery of unknown or impacted media during redevelopment
activities, the site work in this location will halt and the contractor will notify S&ME and
the PD. The materials will be sampled and characterized based on the recommended
sampling frequency for a residential development of one 3-point to 5-point composite,
representative sample with a grab sample for VOCs collected based on the highest
reading from a PID.
Based on the contents, the material will be removed and transported off-site for proper
disposal by a qualified environmental waste management company.
Should grossly impacted soil removal be required, confirmatory samples collected from
the newly discovered contaminant source area(s) will be submitted to a North Carolina
certified laboratory for analysis. Analytical methods to be employed for these samples
will include the following: VOCs by Method 8260; SVOCs by Method 8270; RCRA Metals
by Methods 6010/7471, and hexavalent chromium by Method 7199. Additional analyses
may be required based on field observations and requirements from NCBRS.
An environmental waste management company will be contracted to clean up any
hazardous substances that may have been released/discovered. Redevelopment activities
will not resume until after released hazardous substances have been removed, and any
explosive or dangerous atmospheric conditions have been mitigated.
Should impacted soils be reused on the site, the NCBRS Project Manager will be notified
within 48 hours and consulted as to potential for further sampling, reporting, and
mitigation.
Soil will need to be tested in accordance with the approved EMP and NCBRS approval
must be obtained prior to re-use.

EMP Version 3, March 2023
PART 1.B. IMPORTED FILL SOIL
NO SOIL MAY BE BROUGHT ONTO THE BROWNFIELDS PROPERTY WITHOUT PRIOR APPROVAL FROM
THE BROWNFIELDS REDEVELOPMENT SECTION. According to the Brownfields IR 15, “Documenting
imported soil (by sampling, analysis, and reporting in accordance with review and written approval
in advance by the Brownfields Redevelopment Section), will safeguard the liability protections
provided by the brownfields agreement and is in the best interest of the prospective
developer/property owner.”
Requirements for importing fill:
☒ Check to confirm that the import volumes outlined below have been confirmed based on
geotechnical evaluations.
1) Will fill soil be imported to the site?................................................ ☒ Yes ☐ No ☐ Unknown
2) If yes, what is the estimated volume of fill soil to be imported?
23,300 cubic yards.
3) If yes, what is the anticipated depth that fill soil will be placed at the property? (If a range
of depths, list the range.)
Based on the cut/fill calculations for the development, fill soil will be placed at depths ranging
from 1 to 10 feet deep. Figure 06 in Appendix II is an engineering plan from PGE showing the
existing elevations and proposed elevations to further illustrate the fill areas.
Figure 10 in Appendix II depicts the "cut" areas in red and the "fill" material areas in blue. The
limited “cut” of surficial soils, show in the red, will remain on-site. The blue “fill” areas will be
filled by the GC with fill materials imported from NCBRS-approved sources. Approximately over
90% of the site will be filled to raise the existing site grades to the proposed higher elevations.
PRIOR TO SOIL PLACEMENT AT THE BROWNFIELDS PROPERTY, a Soil Import Request must be
submitted for DEQ Brownfields review and approval. The request shall consist of a data
package that details:
- Fill source location/history (Phase I if available, current aerials, etc.)
- Analytical data that has been sampled in accordance with the below frequency and
following procedures outlined in the most recent Brownfields Redevelopment Section
Environmental Site Assessment Work Plan Minimum Requirements Checklist (Checklist)
and in accordance with DEQ IHSB Guidelines for Assessment and Cleanup of

At this time, the PD is considering the following local sources of import materials:
• Vulcan Quarry – 4401 Patterson Ave, Winston-Salem, NC
• Martin Marietta – Salem Stone Quarry - 4572 High Point Road, Kernersville, NC
The PD understands that the above-identified potential fill sources have not achieved pre-
approved status from NCBRS and will require soil import sampling and analysis in accordance
with the table above and other NCBRS requirements (at a minimum analyzed for VOCs, SVOCs, 8
RCRA Metals and hexavalent chromium).
As of the date of this revised EMP, up to 3,500 cubic yards of soils were approved by NCBRS for
export from the Carolina Medical Electronics site to the proposed 450 Polo Road development.
The approval was granted by NCBRS in correspondence dated August 3, 2023.
As previously discussed with NCBRS, the PD is evaluating other potential sources of import fill
including other local developments and NCBRS-approved Brownfields sites, and/or the use of a
borrow source(s). S&ME and the PD will update and request approval from NCBRS for potential
sources of fill materials, including sampling and analysis of potential import soil.
The PD assumes that stone, gravel or similar materials (virgin material from NCBRS-approved
sources) do not require testing under this EMP or NCBRS approval. The PD acknowledges that
recycled materials may require testing.

CONTINGENCY PLAN
In this section, please provide actions that will be taken to identify or manage unknown
potential new sources of contamination. During redevelopment activities, it is not uncommon
that unknown tanks, drums, fuel lines, landfills, or other waste materials are encountered.
Notification to DEQ Brownfields project manager, UST Section, Fire Department, and/or other
officials, as necessary and appropriate, is required when new potential source(s) of
contamination are discovered. These Notification Requirements were outlined on Page 1 of this
EMP.
Should potentially impacted materials be identified that are inconsistent with known site
impacts, the DEQ Brownfields project manager will be notified, and a sampling plan will be
prepared based on the EMP requirements and site-specific factors. Samples will generally be
collected to document the location of the potential impacts.
Check the following chemical analysis that are to be conducted on newly identified releases:

EMP Version 3, March 2023
Sub-Grade Feature/Pit:
Sub-grade features or pits are not anticipated to be encountered during site development. In the
event a sub-grade feature of concern is discovered, the GC will coordinate with S&ME for the
appropriate investigation and/or removal of the sub-grade feature or pit. S&ME will notify the
NCBRS Project Manager of the discovery within 48 hours and discuss whether additional
environmental assessment and/or remediation is necessary during site development
Buried Waste Material – Note that if buried waste, non-native fill, or any obviously filled materials
is encountered, the DEQ Brownfields Redevelopment Section must be notified to determine if
investigation of landfill gases is required:
In the event that buried solid waste material is discovered, the GC will coordinate with S&ME for
the appropriate investigation and/or segregation of the buried waste material pending
characterization for disposal. S&ME will notify the NCBRS Project Manager of the discovery within
48 hours and discuss whether additional environmental assessment and/or remediation is
necessary during site development
In the event that buried solid waste is encountered, S&ME will conduct screening of the worker
breathing zone for the potential presence of landfill gas (LFG) including methane and hydrogen
sulfide levels.
Re-Use of Impacted Soils Onsite:
Soils from the property will be beneficially reused as noted in the sections above. VOC-impacted
soils will not be placed under buildings or under impervious surfaces directly connected to occupied
spaces.
If unknown, impacted soil is identified onsite, management onsite can be considered after the
project team provides the necessary information, outlined in Part 1.A. Item 11, for Brownfields
project manager approval prior to final placement onsite.

S&ME Project No. 23350213
Dear Seth:
S&ME, Inc. (S&ME) has prepared this Final Grade Sampling and Analysis Plan (Plan) on behalf of 450 Polo Road,
LLC, the Prospective Developer (PD) for the development.
The purpose of this Plan is to obtain North Carolina Department of Environmental Quality (NCDEQ), Brownfield
Redevelopment Section (BRS) approval of the proposed soil sampling locations within the anticipated final
development areas.
The following sections provide the (1) regulatory requirements for the proposed sampling activities based on the
BRS’s comments and the Environmental Management Plan (EMP) for the development, (2) proposed soil sampling
methodologies and laboratory analyses and (3) estimated sampling and reporting schedule based on the current
project construction schedule.
Proposed Development
The proposed development is for 17 2-story and 3-story townhomes (“For-Rent-Only” residential units). The
development will include a total of approximately 23,000 square feet (SF) of residential townhome/residential unit
footprints, residence access sidewalks, landscaped areas surrounding the development and within the parking
areas, paved parking areas and a Clubhouse area with a pool. Based on the EMP, approximately 23,400 cubic
yards of imported fill will be brought onsite as part of the development based on the cut/fill calculations.
Based on the most recent site plan included in the EMP, nearly 167,000 SF will be disturbed during site
development and approximately 60,600 SF of the proposed development will be pervious areas (areas not
“capped” by buildings, sidewalks, paved parking areas, etc.), as shown on Figure 1, which will be available for final
grade soil quality sampling and analysis.

Soil Sampling Locations, Methodology and Laboratory Analysis
Based on comments provided by NCBRS during August 2023, Figure 1 shows the sampling locations within the
NCBRS-identified areas of the development and Table 1 summarizes the proposed soil sampling and analysis.
The approximate square footage for Sampling Areas 1 through 7 are provided in Table 1 and summarized below:
Area 1 - 8,900 SF
Area 2 – 6,350 SF
Area 3 – 9,100 SF
Area 4 – 6,700 SF
Area 5 – 5,700 SF
Area 6 – 14,000 SF
Area 7 – 9,900 SF
Soil sampling will be conducted in accordance with the sampling procedures outlined in the NCDEQ Inactive
Hazardous Site Branch’s (IHSB) Guidelines for Assessment and Cleanup of Contaminated Sites (September 2022).
Soil type, relative moisture content, and other lithologic characteristics will be documented in the field. Each soil
sample will be composited from four aliquot locations by advancing a decontaminated hand auger to
approximately 2-feet below ground surface (bgs) at each location.
The soils from each sample location will be divided equally with one-half placed in a sealed plastic bag that is
placed on ice within a cooler and the other half placed in a sealed plastic bag that is allowed to volatilize for
approximately 5 to 10 minutes. After the volatilization period, the headspace of the second plastic bag (not
placed on ice) will be screened for volatile vapors using a photo-ionization detector (PID). A grab sample for VOC
analysis will be collected from the corresponding sealed plastic bag that had been stored on ice from the location
exhibiting the highest PID reading. For composite sample collection, soils from the sealed plastic gas (placed on
ice) from each set of borings will be composited using a decontaminated stainless-steel bowl and spoon via the
sample homogenization procedures outlined in the U.S. Environmental Protection Agency’s SESDPROC-300-R3
(June 11, 2020) guidance. Therefore, S&ME proposes the following:
Seven (7) grab or discrete soil samples will be collected from the one to foot bgs interval for analysis of
volatile organic compounds (VOCs) by EPA Method 8260. The grab or discrete soil sample will be
selected based on field screening results (e.g., results from a PID, visual or olfactory observations).
Seven (7) composite samples (4-point composites) will be collected from each Sampling Area for analysis
of semi-volatile organic compounds (SVOCs) by EPA Method 8270, the eight (8) Resource Conservation
and Recovery Act (RCRA) metals by EPA Methods 6010/7471 and hexavalent chromium by EPA Method
7199.
Each composite soil sample will be comprised of a minimum of four (4) sub-samples (e.g., 4-point
composite) collected from the ground surface to approximately 2 feet bgs.
The locations of the discrete samples sub-samples will be recorded using Global Positioning System (GPS)
coordinates using a hand-held device (or equivalent) and identified on a map.

S&ME will collect one duplicate discrete sample and one composite sample for the analysis parameters
detailed above per NCDEQ quality assurance/quality control (QA/QC) guidelines.
Sample Handling and Laboratory Quality Control Procedures
Soil samples will be placed into laboratory-provided containers and submitted under strict chain-of-custody
protocol to a NCDEQ and NELAP-certified analytical laboratory for analysis. Laboratory reporting limits (RLs) and
method detection limits (MDLs) used by the designated laboratory will meet the applicable NCDEQ Division of
Waste Management (DWM) PSRGs (January 2023), to the extent feasible.
Concentrations detected between the RL and MDL will be reported as estimated values and flagged in the
laboratory analytical report with a “J” qualified. Level II QA/QC will be reported by the laboratory in the analytical
report deliverable.
Reporting
After receipt and review of the laboratory analytical results (anticipated in August/September 2024), S&ME will
prepare a Final Grade Sampling and Analysis Report (Report) for NCBRS’ review and approval. The Report will
include the following:
Summary of the field activities and laboratory analytical results in a tabulated format including a figure
showing the approximate sampling locations.
A comparison to the applicable NCDEQ Residential PSRGs.
Analytical results will be evaluated using the most up-to-date version of the NCDEQ Risk Calculator.
Copies of the laboratory analytical reports, field notes and tabulated PID results recorded during the
sampling activities.
Closing
Please contact the undersigned with any questions or comments regarding this Plan.
Sincerely,
