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 information for capital investment and jobs created as estimated by your final redevelopment
plans for the Brownfields Property:

1. Estimated capital investment in redevelopment project: Approximately $140MM
2. Estimated jobs created:

PART 1. SOIL
1) Known or suspected contaminants in soil (list general groups of contaminants):
In September 2021, H&H conducted Phase II Environmental Site Assessment (ESA) activities at
the Site which included collection of four (4) composite shallow soil samples (COMP-1 through
COMP-4) in areas planned for disturbance during future grading activities and one (1) targeted
soil sample (SB-1) in an area of potential impacts based on results of field screening. In addition,
H&H conducted in situ soil assessment activities at the Site in February 2023. Forty-one (41) soil
samples were collected for laboratory analysis from one hundred ten (110) soil borings advanced
within twenty-two (22) in situ soil characterization sections (EX-1 through EX-22). The soil
borings were advanced in areas planned for excavations associated with the proposed
redevelopment of the Brownfields property.

Soil sample analytical results were compared to the North Carolina Department of
Environmental Quality (DEQ) Preliminary Soil Remediation Goals (PSRGs) dated January 2023. In
addition, metals concentrations were compared to background metals concentrations
established for nearby Brownfields properties and published concentrations for naturally
occurring levels. Metals concentrations detected in the in situ soil characterization samples were
also compared to background ranges established for the Reeves and Old 27 Land Clearing and
Inert Debris (LCID) landfills to assist in off-Site disposal determination.

A tabular summary of the Phase II ESA shallow composite and grab soil sample analytical data is
included in Table 1. A tabular summary of the in situ soil characterization sample analytical data
is included in Table 2. Phase II ESA composite and grab soil sample locations are shown in Figure
3 and shallow soil sample compound concentrations are shown in Figure 4. In situ soil sample
locations and characterization sections are shown in Figure 5. A brief summary of the soil
assessment results is provided below.

Volatile Organic Compounds (VOCs)
Laboratory analytical results indicate that low levels of several VOCs have been detected in soil
samples (both shallow composite soil samples and in situ soil samples) collected at the Site at
concentrations above laboratory method detection limits, but below the DEQ Residential PSRGs.

Semi-Volatile Organic Compounds (SVOCs)
Trace levels of several SVOCs have been detected in the shallow composite soil samples collected
at the Site at concentrations above laboratory method detection limits, but below the DEQ
PSRGs with the exception of benzo(a)pyrene which was detected in composite soil samples
COMP-1 and its duplicate soil sample SOIL-DUP (up to 0.20 J milligram per kilogram {mg/kg}),
COMP-2 (0.13 J mg/kg), and COMP-3 (0.77 mg/kg) at concentrations above the DEQ Residential

9
EMP Version 3, March 2023
PSRG of 0.11 mg/kg.

Laboratory analytical results indicated the presence of several polycyclic aromatic hydrocarbons
(PAHs) at concentrations above the laboratory method detection limits in select in situ soil
samples, but below the DEQ PSRGs with the exception of benzo(a)anthracene, benzo(a)pyrene,
benzo(b)fluoranthene, dibenz(a,h)anthracene, and indeno(1,2,3-cd)pyrene which were detected
in in situ soil samples EX-2/EX-DUP1 (0-4), EX-6/EX-DUP3 (0-4), EX-6 (4-8), EX-6 (8-12), EX-7 (0-4),
EX-9 (4-8), EX-10 (0-4), EX-11 (4-8), EX-12 (0-4), EX-13 (0-3), and EX-15/EX-DUP2 (0-3). No other
SVOCs have been detected in Site soil at concentrations above the PSRGs (see Table 2).

Metals
Low levels of several metals were detected at concentrations consistent with naturally occurring
background levels in shallow composite soil samples and in situ soil characterization samples
collected at the Site.

Although below the DEQ PSRGs, total chromium (up to 268 mg/kg) was detected in soil
characterization samples EX-1 (8-12), EX-4 (8-12), EX-8 (4-8) and lead (up to 158 mg/kg) was
detected in EX-9 (4-8) at concentrations exceeding the “Rule of 20” for hazardous characteristic
of 100 mg/kg. Toxicity Characteristic Leaching Procedure (TCLP) laboratory analytical results for
these samples indicate that chromium and lead were not detected in the leachate samples at
concentrations above the Maximum Concentration for Toxicity Characteristics of 5 milligrams per
liter (mg/L).

The metals concentrations detected in Site soil appear to be generally consistent with naturally
occurring levels and consistent with concentrations detected in samples collected at the Reeves
and Old 27 LCID landfills (Table 2). No other metals were detected at concentrations exceeding
the DEQ PSRGs, naturally occurring background levels, or the Rule of 20 for potential hazardous
characteristics.

2) Depth of known or suspected contaminants (feet):
As described above, the PAH benzo(a)anthracene was detected above the DEQ PSRGs in five (5)
in situ soil characterization sections (EX-6/EX-DUP3 (0-4), EX-7 (0-4), EX-12 (0-4), EX-13 (0-3), and
EX-15/EX-DUP2 (0-3)) at depths up to 4 ft bgs; the PAH benzo(a)pyrene was detected above the
DEQ PSRGs in ten (10) in situ soil characterization sections (EX-2/EX-DUP1 (0-4), EX-6/EX-DUP3
(0-4), EX-6 (4-8), EX-7 (0-4), EX-9 (4-8), EX-10 (0-4), EX-11 (4-8), EX-12 (0-4), EX-13 (0-3), and EX-
15/EX-DUP2 (0-3)) at depths up to 8 ft bgs; the PAH benzo(b)fluoranthene was detected above
the DEQ PSRGs in three (3) in situ soil characterization sections (EX-6/EX-DUP3 (0-4), EX-6 (8-12),
and EX-15/EX-DUP2 (0-3) at depths up to 12 ft bgs; the PAH dibenz(a,h)anthracene was detected
in one (1) in situ soil characterization section (EX-6/EX-DUP3 (0-4)) at a depth up to 4 ft bgs; and
the PAH indeno(1,2,3-cd)pyrene was detected in one (1) in situ soil characterization section (EX-
6/EX-DUP3 (0-4)) at a depth up to 4 ft bgs.

10
EMP Version 3, March 2023
3) Area of soil disturbed by redevelopment (square feet):
Leveling the Site for construction of the Site buildings will include clearing and grading the entire
Brownfields property (approximately 130,000 square feet). A copy of the grading plan and cut-
fill analysis are provided as Appendix C.

4) Depths of soil to be excavated (feet):
As indicated in the grading plans and cut-fill analysis, areas planned for cut are primarily
associated with the construction of the two mixed use multi-story apartment buildings and
associated parking decks. Cut depths range from less than 1 ft bgs to approximately 12 ft bgs.
Other discrete areas may include deeper excavations for installation of deeper foundational
footers, elevator banks, utility banks, etc.

5) Estimated volume of soil (cubic yards) to be excavated (attach grading plan):
Based on the cut-fill analysis, approximately 28,000 cubic yards of soil will be excavated
and/or cut from the Site during proposed grading and construction activities.

6) Estimated volume of excavated soil (cubic yards) anticipated to be impacted by contaminants:
Based on results of in situ soil characterization assessment activities, approximately 8,420 cubic
yards of soil containing compounds at concentrations above the DEQ PSRGs will be generated
during redevelopment. Soil generated during excavations in impacted evaluation sections will be
managed on-Site beneath impervious materials, loaded onto trucks and transported off-Site for
disposal at a municipal solid waste landfill, or to another location with DEQ prior approval.

7) Estimated volume of contaminated soil expected to be disposed of offsite, if applicable:
Based on review of the grading plan and cut-fill analysis, up to approximately 23,300 cubic
yards of excess soil generated for the construction of the two mixed use multi-story apartment
buildings may need to be transported off-Site. Based on the results of in situ soil
characterization assessment activities, no compounds were detected at concentrations above
the DEQ PSRGs (or background levels in the case of metals) in samples collected in evaluation
sections EX-1 (0-12), EX-2 (4-12), EX-3 (0-12), EX-4 (0-8), EX-5 (0-12), EX-7 (4-12), EX-8 (0-4), EX-
9 (0-4), EX-10 (4-8), EX-11 (0-4), EX-12 (4-8), EX-14 (0-6), EX-16 (0-3), EX-17 (0-2), EX-18 (0-2),
EX-19 (0-2), EX-20 (0-3), EX-21 (0-6), and EX-22 (0-6). Approximately 19,990 cubic yards of
excess soil generated during excavation/grading within the above evaluation sections will be
loaded onto trucks and transported to the Reeves and/or Old 27 LICD landfills for disposal.
Approximately 8,420 cubic yards of impacted soil generated during excavation/grading within
in situ soil evaluation sections EX-2 (0-4), EX-4 (8-12), EX-6 (0-12), EX-7 (0-4), EX-8 (4-8), EX-9
(0-4), EX-10 (0-4), EX-11 (4-8), EX-12 (0-4), EX-13 (0-3), and EX-15 (0-3) will be managed on-Site
beneath impervious materials, transported off-Site for disposal in a municipal solid waste
landfill such as Republic Services located in Concord, NC, or to another location with DEQ prior
approval. A tabular summary of soil in situ soil characterization export options is provided as
Appendix D.

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:
During soil disturbance at the Site, the workers or contractors will observe soil for obvious
evidence of potential impacts. Evidence of potentially impacted soil includes a distinct
unnatural color, strong odor, or filled or previously disposed materials of potential
environmental concern (i.e., chemicals, tanks, lifts, etc.). Should the above be observed
during Site work, the contractor will contact the project environmental professional to
observe the suspect condition. If the project environmental professional confirms that
the material may be impacted, then the procedures below will be implemented. In
addition, the DEQ Brownfields project manager will be contacted within 48 hours to
advise of the condition.

Soil sample collection
☐ Yes
Click or tap here to enter text.

☒ 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:
If significant soil impact is encountered during grading and/or installation or removal of
utilities, excavation will proceed only as far as needed to allow grading or other
construction-related activity to continue and/or only as far as needed to allow alternate
corrective measures as described below. Suspect significantly impacted soil excavated
during redevelopment activities may be stockpiled and covered in a secure area to allow
construction to progress. Suspect impacted soil will be stockpiled in accordance with
Figure 1, NCBP Diagram for Temporary Containment of Impacted or Potentially Impacted
Soil.

At least one representative soil sample (no less than 3 aliquot soil samples) at a sample

14
EMP Version 3, March 2023
ratio of 1 soil sample per approximately 1,000 cubic yards of soil will be collected for
analysis of total VOCs, SVOCs, RCRA metals, and hexavalent chromium. If the soil sample
laboratory analytical results indicate that the soil could potentially exceed the hazardous
characteristic criteria based on the Rule of 20, then the soil will also be analyzed by TCLP
methods for those compounds that could exceed the hazardous characteristic criteria.
Potentially impacted soil will be managed in the manner described below based upon the
soil sample laboratory analyses:

i. If no organic compounds or metals are detected in a sample (other than those
attributable to sampling or laboratory artifacts) above unrestricted use PSRGs,
the TCLP concentrations are below hazardous waste criteria, and the cumulative
risk calculator results are acceptable, then the soil will be deemed suitable for use
as on-Site fill or as off-Site fill. The proposed location(s) for off-Site placement of
soil (other than a Municipal Solid Waste Landfill [MSWLF]) along with the
receiving facility’s written approval for acceptance of the soil will be provided to
DEQ for approval prior to taking the soil off-Site.
ii. If detectable levels of compounds are found which do not exceed Residential PSRGs
(other than those attributable to sampling or laboratory artifacts) and the TCLP
concentrations are below hazardous waste criteria, then the soil may be used on-
Site as fill without conditions.
iii. If detectable levels of compounds are found which exceed the Residential PSRGs
(other than those are attributable to sampling or laboratory artifacts or which are
consistent with background levels for metals) and the TCLP concentrations are
below hazardous waste criteria, then the soil, may be used on-Site as fill below
impervious cover, at least 2 ft of compacted demonstrably clean soil, or overlain
by a geotechnical fabric. If the impacted soil with concentrations above
Residential PSRGs is moved to an on-Site location, its location and depth will be
documented and provided to DEQ.
iv. Impacted soil may be transported to a MSWLF or DEQ permitted landfarm provided
that the soil is accepted at the disposal facility. DEQ Solid Waste Section and DEQ
Brownfields Program approval will be requested for any potential export to an
off-Site facility other than an MSWLF or DEQ permitted landfarm. If soil is
transported to an MSWLF or DEQ permitted landfarm, the facility’s written
approval in the form of waste manifests or similar will be included in an annual
redevelopment summary report. In the unlikely event that the sample data
indicates concentrations above TCLP hazardous characteristic criteria, then the
soil must be transported off-Site to a facility permitted to accept hazardous
wastes.

* Please note that should the PD elect to transport export soil to a MSWLF, DEQ
permitted landfarm, or to a DEQ Brownfields pre-approved receiving facility, soil will be
direct-loaded onto trucks for transport off-Site.

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?
Based on conversations with the PD and the available grading plans, approximately 500 cubic
yards of fill will need to be placed in the eastern and western portions of the Site to achieve final
grade elevations. Current grading plans include the generation of approximately 23,800 cubic
yards of cut. Soil generated during excavations or cut as part of grading will be used on-Site in
areas planned for fill. There is no plan to import soil to the Site for use as fill.

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.)
In general, fill areas associated with the proposed redevelopment are located in the eastern and
western portions of the Site (Figure 5 and Appendix C). The thickness of fill ranges from
approximately 1ft to 3ft.

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

PART 1.C. SOIL EXPORT

NO SOIL MAY LEAVE THE BROWNFIELDS PROPERTY WITHOUT APPROVAL FROM THE
BROWNFIELDS REDEVELOPMENT SECTION. Failure to obtain approval may violate a brownfields
agreement causing a reopener or jeopardizing eligibility in the Section, endangering liability
protections and making said action possibly subject to enforcement. Justifications provided
below must be approved by the Section in writing prior to completing transport activities. Refer
to Brownfields IR 15 for additional details.

1) If export from the Brownfields Property is anticipated, export soil must be sampled at a
frequency of one sample per 1,000 yd3 consisting of a 3-point composite sample with a
grab sample for VOCs based on the highest PID reading. Samples shall be analyzed at a
minimum for VOCs, SVOCs, and RCRA metals plus any site specific COCs.

20
EMP Version 3, March 2023
If other special considerations apply, discuss:
In situ soil characterization assessment activities have been complete at the Site. Based on results
of the assessment activities, approximately 19,800 cubic yards of excess soil that does not contain
compound concentrations above the PSRGs (or background levels in the case of metals) will be
transported off-Site to a LCID landfill, or other locations with DEQ prior approval. Approximately,
8,420 cubic yards of excess soil that contains compound concentrations above the PSRGs (or
background levels in the case of metals) will be transported off-Site for disposal at a MSWLF, or
other location with DEQ prior approval. A tabular summary of in situ soil characterization export
options is provided in Appendix D.

PART 1.D. MANAGEMENT OF UTILITY TRENCHES

☐ Install liner between native impacted soils and base of utility trench before filling with clean fill
(Preferred)

☒ Last out, first in principle for impacted soils (if soil can safely be reused onsite and is not a
hazardous waste), i.e., impacted soils are placed back at approximately the depths they were
removed from such that impacted soil is not placed at a greater depth than the original depth
from which it was excavated.

☒ Evaluate whether necessary to install barriers in conduits to prevent soil vapor transport,
and/or degradation of conduit materials due to direct impact with contaminants.
☒ If yes, provide specifications on barrier materials or provide the results of this evaluation in the
Vapor Mitigation Plan. Note that if vapor mitigation is planned for site buildings, utility corridors
will need to be evaluated as part of mitigation designs:
The PD plans to install a vapor intrusion mitigation system (VIMS) during construction of the
mixed use multi-story apartment buildings. As part of the VIMS design, the locations of sub-
grade utilities will be evaluated to confirm that the proposed VIMS will effectively minimize
potential vapor intrusion from potential lateral migration of vapors through utility trenches.
The Vapor Intrusion Mitigation Plan will be submitted under separate cover.

☐ If no, include rationale here:

☒ Unknown, details to be provided in the Vapor Mitigation Plan for site buildings

Other comments regarding managing impacted soil in utility trenches:
Although not anticipated, if evidence of contaminated soil and/or vapors (e.g., unusual odors
and/or stained soil) is encountered in utility trenches during redevelopment activities, the trench
will be evacuated, and appropriate safety screening of the vapors will be performed to protect
workers. If results indicate further action is warranted in response to vapors to protect workers,
appropriate engineering controls (such as use of industrial fans) will be implemented.

21
EMP Version 3, March 2023
The contractor and workers will observe soil for potential impacts during utility installation
activities. Evidence of potential significant impacted soil includes a distinct unnatural color,
strong odor, or filled or previously disposed materials of concern (i.e., chemicals, tanks, drums,
etc.). Should the above be noted during utility work, the contractor will contact the project
environmental professional to observe the suspect condition and screen the soil using a PID or
other similar vapor field screening instrument. If the project environmental professional
confirms that the material may be impacted, then the procedures outlined above in Managing
On‐Site Soil (Part 1.A.) will be implemented. In addition, the environmental professional will
contact the DEQ Brownfields project manager within 48 hours to advise that person of the
condition.
PART 2. GROUNDWATER

1) What is the depth to groundwater at the Brownfields Property?
During assessment activities conducted at the Site in September 2021, the depth to
groundwater was measured at depths ranging from approximately 8 ft bgs in the southwestern
portion of the Site to approximately 13 ft bgs in the northern portion of the Site. A tabular
summary of temporary monitoring well construction details and groundwater elevations are
provided as Table 3. Locations of the temporary monitoring wells installed during the
September 2021 assessment activities are shown in Figure 3.

2) What is the maximum depth of soil disturbance onsite?
As noted above, areas planned for cut are primarily associated with the construction of the
two mixed use multi-story apartment buildings and associated podium-style parking decks.
Cut depths range from less than 1 ft bgs to approximately 12 ft bgs. Other discrete areas may
include deeper excavations for the installation of deeper foundational footers, elevator banks,
utility banks, etc.

3) Is groundwater known to be contaminated by ☒onsite ☐offsite ☐both or ☐unknown
sources? Describe source(s):
Previous groundwater assessment at the Brownfields property included the collection of four
(4) groundwater samples for laboratory analysis. Locations of previous groundwater samples
are shown in Figure 3. A tabular summary of groundwater sample laboratory analytical results
is included as Table 4, and the singular compound concentration exceeding the DEQ Vapor
Intrusion Groundwater Screening Levels (GWSLs) is shown in Figure 6. No compounds were
detected at concentrations above the DEQ NCAC 15A 2L Groundwater Quality Standards (2L
Standards) in groundwater samples collected at the Site. A brief summary of the groundwater
assessment results is provided below.
Organic Compounds
Groundwater assessment results indicate that low levels of chloroform (up to 14.6 micrograms
per liter {µg/L}) were detected at concentrations above the DEQ Residential and Non-
Residential Vapor Intrusion GWSLs of 0.81 µg/L and 3.6 µg/L, respectively in the TMW-2
groundwater sample and its duplicate groundwater sample collected in the northern and
hydraulically upgradient portion of the Site. No other organic compounds were detected at
concentrations above the DEQ Vapor Intrusion GWSLs in remaining groundwater samples

22
EMP Version 3, March 2023
collected at the Site.
Metals
Low levels of several metals including arsenic (up to 0.316 J µg/L), barium (up to 69.5 µg/L), total
chromium (1.56 J µg/L), lead (2.92 µg/L), and selenium (up to 0.609 J µg/L) were detected at
concentrations above the laboratory method detection limits, but below the 2L Standards in
groundwater samples collected at the Site.

4) What is the direction of groundwater flow at the Brownfields Property?
Based on survey data and depth to groundwater measurements, the direction of groundwater is
estimated to be to the southeast toward Little Sugar Creek. This is consistent with surface
topography (Figure 1).

5) Will groundwater likely be encountered during planned redevelopment activities (e.g.
footer/utility construction or helical pilings?)
☒Yes ☐No
If yes, describe these activities:
Groundwater was measured at depths ranging from approximately 8 ft bgs in the southwestern
portion of the Site to approximately 13 ft bgs in the northern portion of the Site. Groundwater
may be encountered during redevelopment activities that include deeper excavations for the
proposed parking deck(s) and/or deeper foundational components associated with the
proposed building(s). If groundwater is encountered during redevelopment activities, the
procedures outlined below will be implemented.

In the event that groundwater is encountered during redevelopment activities (even if no is
checked above), list activities for contingent management of groundwater (e.g., dewatering
of groundwater from excavations or foundations, containerizing, offsite disposal, discharge to
sanitary sewer, NPDES permit, or sampling procedures).
If groundwater is encountered during redevelopment, appropriate worker safety measures will
be undertaken if groundwater gathers in an open excavation within an area determined to be
impacted (based on previous sampling data, strong odor, unnatural color, sheen, etc.) during
construction activities. The contractor will contact the environmental professional to observe
the area(s) suspected to be impacted. The accumulated water will be allowed to
evaporate/infiltrate to the extent that the time for dissipation does not disrupt the construction
schedule. Should the time needed for the natural dissipation of accumulated water be deemed
inadequate, the water will be tested for the presence of VOCs, SVOCs, and RCRA metals and
disposed of at an appropriate off‐Site facility (if impacted), or tested and discharged to the storm
sewer (if not impacted above DEQ surface water standards) in accordance with applicable
municipal and State regulations for erosion control and construction stormwater control as
provided in 15A NCAC 2H.0106(f). Groundwater encountered in areas of the Site where no
compounds have been identified at concentrations above the surface water quality screening
criteria based on results of previous assessments will be discharged to the municipal storm
sewer in accordance with applicable municipal and State regulations as provided in 15A NCAC
2H.0106(f).

6) Are monitoring wells currently present on the Brownfields Property?.................☐Yes ☒No
If yes, are any monitoring wells routinely monitored through DEQ or other
agencies?..................................................................................................................☐Yes ☐No

23
EMP Version 3, March 2023
7) Please check methods to be utilized in the management of known and previously
unidentified wells.
☒ Abandonment of site monitoring wells in accordance with all applicable regulations. It
is the Brownfields Redevelopment Section’s intent to allow proper abandonment of
well(s) as specified in the Brownfields Agreement, except if required for active
monitoring through another section of DEQ or the EPA.
☐ Location of existing monitoring wells marked
☐ Existing monitoring wells protected from disturbance
☒ Newly identified monitoring wells will be marked and protected from further
disturbance until notification to DEQ Brownfields can be made and approval for
abandonment is given.

8) Please provide additional details as needed:

Please note, disturbance of existing site monitoring wells without approval by DEQ is not
permissible. If monitoring wells are damaged and/or destroyed, DEQ may require that the PD
be responsible for replacement of the well.

PART 3. SURFACE WATER
1) Is surface water present at the property? ☐ Yes ☒ No
2) If yes, attach a map showing the location of surface water at the Brownfields Property
3) Is surface water at the property known to be contaminated? ☐ Yes ☒ No ☐ Unknown
4) Will workers or the public be in contact with surface water during planned redevelopment
activities or as part of the final redevelopment? ☐ Yes ☒ No
5) In the event that contaminated surface water is encountered during redevelopment
activities, or clean surface water enters open excavations, list activities for management of
such events (e.g. flooding, contaminated surface water run‐off, stormwater impacts):
Surface water features are not present at the site.
If surface water run‐off gathers in an open excavation within an area suspected to be impacted
during construction activities, appropriate worker safety and groundwater management
measures will be undertaken. The contractor will contact the environmental professional to
observe the area(s) suspected to be impacted. The accumulated water will be allowed to
evaporate/infiltrate to the extent that the time for dissipation does not disrupt the construction
schedule. Should the time needed for natural dissipation of accumulated water be deemed
inadequate, the water will be tested for the presence of VOCs, SVOCs, and RCRA metals and
disposed off‐site (if impacted), or tested and discharged to the storm sewer (if not impacted
above DEQ surface water standards) in accordance with applicable municipal and State
regulations for erosion control and construction stormwater control as provided in 15A NCAC
2H.0106(f).

DEQ will be notified if newly identified monitoring wells are discovered at the Brownfields property.

24
EMP Version 3, March 2023
PART 4. SEDIMENT
1) Are sediment sources present on the property? ☐ Yes ☒ No
2) If yes, is sediment at the property known to be contaminated? ☐ Yes ☐ No ☐ Unknown
3) Will workers or the public be in contact with sediment during planned redevelopment
activities? ☐ Yes ☒ No
4) Attach a map showing the location of known contaminated sediment at the property.
5) In the event that contaminated sediment is encountered during redevelopment activities, list
activities for management of such events (stream bed disturbance):
Not applicable

PART 5. SOIL VAPOR

1) Do concentrations of volatile organic compounds at the Brownfields property exceed the
vapor intrusion screening levels (current version) in the following media:

Groundwater Exterior Soil Vapor Sub-Slab Soil Vapor
Residential ☒ Yes ☐ No
☐ Unknown
☒ Yes ☐ No
☐ Unknown
☒ Yes ☐ No
☐ Unknown
Commercial ☒ Yes ☐ No
☐ Unknown
☒ Yes ☐ No
☐ Unknown
☐ Yes ☒ No
☐ Unknown

2) Attach a map showing the locations of all soil vapor samples including any soil vapor
contaminants that exceeds screening levels and overlays planned site development features.

3) If applicable, at what depth(s) is exterior soil vapor known to be contaminated?
Assessment activities completed in September 2021 included the collection of eight exterior soil gas
samples and four sub-slab soil gas samples for laboratory analysis. Locations of the soil gas samples
are shown in Figure 3, and tabular summaries of the laboratory analytical data in comparison to the
DEQ Vapor Intrusion Sub-slab and Exterior Soil Gas Screening Levels (SGSLs) are provided in Table 5A.
In addition, compound concentrations above the DEQ Vapor Intrusion SGSLs are shown in Figure 7.

As shown in Table 5A, several compounds were detected at concentrations above the laboratory
method detection limits in each soil gas sample. Chloroform (up to 460 micrograms per cubic meter
{µg/m3}) was identified at concentrations above the DEQ Residential and/or Non-Residential SGSLs in
6 of the 8 soil gas samples. In addition, several petroleum-related compounds including benzene (up
to 160 µg/m3), ethylbenzene (up to 1,000 µg/m3), naphthalene (up to 17,000 µg/m3), 1,2,4-
trimethylbenzene (up to 4,000 µg/m3), 1,3,5-trimethylbenzene (up to 2,700 µg/m3), and xylenes (up
to 2,900 µg/m3) were detected at concentrations above the DEQ Residential or Non-Residential SGSLs
in soil gas samples collected at the Site.

Hypothetical worst-case scenario risk calculator results for the soil gas to indoor air vapor intrusion

25
EMP Version 3, March 2023

4) If applicable, at what depth(s) is sub‐slab soil vapor known to be contaminated?
☒0‐6 inches ☐Other, please describe:
Assessment activities previously completed at the Site included collection of four sub-slab soil gas
samples within existing Site buildings. A tabular summary of the sub-slab soil gas sample
laboratory analytical data in comparison to the DEQ SGSLs is provided in Table 5B and locations of
the sub-slab soil gas samples are shown in Figure 3. Compound concentrations above the DEQ
Vapor Intrusion SGSLs in sub-slab soil gas are shown in Figure 7.

As shown in Table 5B, several compounds were detected at concentrations above the laboratory
method detection limits in each soil gas sample. A low level of TCE (15 µg/m3) was detected at a
concentration above the DEQ Residential SGSL in sub-slab soil gas sample SSV-1 collected within
Building 1 located along the northern Site boundary. No other compounds were detected at
concentrations above the DEQ SGSLs in sub-slab soil gas samples collected at the Site.

As stated above, hypothetical worst-case scenario risk calculator results for the soil gas to indoor
air vapor intrusion pathway exceed the cumulative risk threshold values for a resident. However,
the risk calculator results are primarily driven by petroleum-related compounds concentrations
detected in the soil gas sample collected from the southeastern portion of the Site (SG-6) and the
potential for structural vapor intrusion are limited to a discrete area and are not widespread at
the Site. However, the PD plans to install a vapor intrusion mitigation system during construction
of the proposed apartment buildings to address potential risks of structural vapor intrusion

5) Will workers encounter contaminated exterior or sub-slab soil vapor during planned
redevelopment activities? ☐ Yes ☐ No ☒ Unknown
In the event that apparent contaminated soil vapor is encountered (based on elevated PID
readings, unusual odors, etc.) during redevelopment activities (trenches, manways, basements or
other subsurface work,) list activities for management of such contact, INCLUDING notification to
DEQ within 48 hours of identification of the issue for determination of additional requirements:
The environmental professional will remain on call on an as-needed basis during redevelopment
activities at the Site. If contaminated soil vapors are suspected during redevelopment activities
(based on unusual or strong odors, dizziness, lightheadedness, coughing, difficulty breathing,
etc.), the excavation area will immediately be evacuated, and the environmental professional will
be called to perform appropriate safety screening of the vapors. Safety screening activities
include monitoring the worker breathing zone with a calibrated multi-gas monitor (or similar
instrument[s] capable of detecting VOCs and combustible gases) for VOCs, methane, oxygen,
pathway exceed the cumulative risks threshold values for a resident. However, the risk calculator
results are primarily driven by petroleum-related compounds concentrations detected in the soil gas
sample collected from the southeastern portion of the Site (SG-6) and the potential for structural
vapor intrusion are limited to a discrete area and are not widespread at the Site. However, the PD
plans to install a vapor intrusion mitigation system during construction of the proposed apartment
buildings to address potential risks of structural vapor intrusion.

2) If applicable, attach a map showing the location(s) where indoor air contaminants exceed site
screening levels.
3) If the structures where indoor air has been documented to exceed risk‐based screening levels will
not be demolished as part of redevelopment activities, will workers encounter contaminated
indoor air during planned redevelopment activities? ☐ Yes ☐ No ☐ Unknown ☒ N/A

☒ If no, include rationale here:
No indoor air samples have been collected within the existing Site buildings. The Site buildings
and all other Site features will be razed as part of the proposed redevelopment.
4) In the event that contaminated indoor air is encountered during redevelopment activities, list
activities for management of such contact:

VAPOR INTRUSION MITIGATION SYSTEM
1) Is a vapor intrusion mitigation system (VIMS) proposed for this Brownfields Property?
☒ Yes ☐ No ☐ Unknown

☐ If no or unknown, include rationale here as well as plans for pre-occupancy sampling, as
necessary:

If yes, ☐ VIMS Plan Attached or ☒ VIMS Plan to be submitted separately
If submitted separately provide date:
The PD intends to install a DEQ Brownfields approved passive vapor intrusion mitigation system
designed by a North Carolina licensed Professional Engineer during construction of the proposed
apartment building. The vapor intrusion mitigation plan will be submitted under separate cover.

VIMS Plan shall be signed and sealed by a NC Professional Engineer and follow the DEQ
Brownfields Redevelopment Section’s Vapor Intrusion Mitigation System Design Submittal
Requirements.
In the unlikely event there is evidence of potential indoor air issues (i.e., unusual odors) during future
redevelopment activities, the area will be evacuated and appropriate safety screening of the indoor
air will be performed. If warranted, safety screening procedures will be conducted by an
environmental professional and will include periodically screening by an environmental professional
indoor air for volatile organic vapors with a calibrated photoionization detector when workers
present in the Site buildings identify potential indoor air issues. If results indicate further action is
warranted, appropriate engineering controls (such as use of industrial fans) will be implemented.

27
EMP Version 3, March 2023
Note that approval of this EMP does not imply approval with any vapor intrusion mitigation land
use restrictions or requirements of the recorded or draft Brownfields Agreement and that
separate approval of mitigation measures will be required.

EMP Version 3, March 2023
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:
☒ Minimum Sample Requirements: Volatile organic compounds (VOCs) by EPA Method 8260;
Semi‐volatile organic compounds (SVOCs) by EPA Method 8270; and Metals RCRA List +
Hexavalent Chromium by EPA Method 6020/7199

☐ Pesticides: Specify Analytical Method Number(s):

☐ PCBs: Specify Analytical Method Number(s):

☐ Other Constituents & Analytical Method(s) (e.g. Herbicides)
Please note, if field observations indicate the need for additional analyses, they should
be conducted, even if not listed here.

Please provide details on the proposed methods of managing the following commonly
encountered issues during redevelopment of Brownfields Properties.

Underground Storage Tanks – Note that UST Section guidelines must be followed for sample
frequency during UST closure. Unless damage to onsite structures to remain as part of
redevelopment would occur, USTs shall be removed from the Brownfields Property:
In the event a UST or impacts associated with a UST release are discovered at the Site during
redevelopment activities, the UST and/or UST related impacts will be addressed through the
Brownfields Program. DEQ Brownfields will be notified within 48 hours of discovery of the UST.

If an undocumented UST is encountered, residual fluids (if present) will be removed, sampled for
VOCs, SVOCs, and RCRA metals, and transported off-Site for disposal at a suitable facility based on
the laboratory analytical results. Following the removal of residual fluids, the tank will be assessed
for closure or removal and closure soil sampling will be performed as needed. The number of soil

29
EMP Version 3, March 2023
samples will be consistent with DEQ UST Section guidelines. The soil samples will be submitted for
laboratory analysis of VOCs, SVOCs, RCRA metals, and hexavalent chromium. Impacted soil will be
managed in accordance with the Managing On-Site Soil (Part 1.A.) section outlined above.

If the UST cannot be removed for geotechnical or construction purposes, DEQ will be notified for
approval of in-place closure. Following DEQ approval, closure soil sampling will be performed in
general accordance with the DEQ UST Section guidelines. Where appropriate, the bottom of the
UST may be penetrated before abandonment to prevent fluid accumulation. If the UST contains
residual fluids, the fluids will be removed, sampled for VOCs, SVOCs, and RCRA metals, and
transported off-site for disposal at a suitable facility based on the laboratory analytical results. A
survey plat update may also be needed in the event of in-place closure of USTs, if residual
contamination is left in place above applicable standards.

Sub-Grade Feature/Pit:
If a sub-grade feature or pit is encountered and does not require removal for geotechnical or
construction purposes, it will be filled with soil or suitable fill and construction will proceed. Where
appropriate, the bottom may be penetrated before back filling to prevent fluid accumulation. If the
pit has waste in it, the waste may be set aside in a secure area and will be sampled for waste
disposal purposes for TCLP VOCs, TCLP SVOCs, and TCLP metals and disposed off-site at a permitted
facility or the waste will be managed in accordance with the Managing On-Site Soil (Part 1.A.)
section outlined above, whichever is most applicable based on the type of waste present. If the pit
must be removed and the observed waste characteristics indicate the concrete may potentially be
contaminated to a significant degree, the concrete will be sampled and analyzed by methods
specified by the disposal facility.

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:
If excavation into buried wastes or significantly impacted soils occurs, the contractor is instructed to
stop work in that location and notify the environmental consultant. The environmental consultant
will observe the suspect materials and collect samples if warranted. In this event, confirmation
sampling will be conducted at representative locations in the base and the sidewalls of the
excavation after the waste or significantly impacted soil is removed. The confirmation samples will
be analyzed for VOCs, SVOCs, RCRA metals, hexavalent chromium (or other analyses as appropriate
based on the type of waste material). Information will be provided to DEQ Brownfields regarding
the permitted facility used for disposal of the waste or significantly impacted soil. Areas of
suspected contaminated soil that remain at the site after excavation is complete above the DEQ
Residential PSRGs will be managed pursuant to this plan.

Re-Use of Impacted Soils Onsite:
Please refer to description outlined in the Managing On-Site Soil section (Part 1.A.) of the EMP
above.

30
EMP Version 3, March 2023

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.

If other potential contingency plans are pertinent, please provide other details or scenarios as
needed below:

POST‐REDEVELOPMENT REPORTING

☒ Check this box to acknowledge that a Redevelopment Summary Report will be required for the
project. If the project duration is longer than one year, an annual update is required and will be
