NORTH CAROLINA BROWNFIELDS PROGRAM
ENVIRONMENTAL MANAGEMENT PLAN
This form is to be used to prepare an Environmental Management Plan (EMP) for projects in
the North Carolina Brownfields Program at the direction of a Brownfields project manager.
The EMP is a typical requirement of a Brownfields Agreement (BFA). Its purpose is to clarify
actions to be taken during the 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 resultant EMP to be valid for use, it
must be completed, reviewed by the program, 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 completed 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.
Voluntary Metrics Tab
The NC Brownfields Program 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: $78,000,000
2. Estimated jobs created:
a. Construction Jobs: 100
b. Full Time Post-Redevelopment Jobs: 10

PART 1. Soil
1) Known or suspected contaminants in soil (list general groups of contaminants):
8
EMP Version 2, January 2021
Soil samples were collected for laboratory analysis at the Brownfields property in February 2021
to evaluate the potential for impacts associated with historical on‐Site operations. Soil
assessment activities advancing ten (10) soil borings in areas of concern and areas that will likely
be disturbed during future redevelopment activities. Two (2) composite soil samples were
collected for laboratory analysis from the borings to represent soil that will need to be managed
during grading in the area of the parking deck and the courtyard. A tabular summary of the soil
sample laboratory analytical results is included as Table 1. Soil sample locations are shown in
Figure 3. A summary of the previously completed soil assessment results is provided below:
Volatile Organic Compounds
No volatile organic compounds (VOCs) were detected at concentrations above the laboratory
method detection limits in the soil samples collected at the Brownfields property.
Semi‐Volatile Organic Compounds
No semi‐VOCs (SVOCs) were detected at concentrations above the laboratory method detection
limits in soil samples collected at the Brownfields property.
Metals
Soil sample laboratory analytical results indicate that several metals were detected at
concentrations above the laboratory method detection limits. The metal arsenic (up to 2.03
milligrams per kilogram [mg/kg]) was detected in each soil sample at a concentration above the
DEQ Inactive Hazardous Sites Branch (IHSB) Residential Preliminary Soil Remediation Goals
(PSRG) of 0.68 mg/kg. No other metals were detected at concentrations exceeding the DEQ IHSB
PSRGs at the Site. The detected metals, including arsenic, are consistent with background
concentrations for the Site area and are considered naturally occurring.
2) Depth of known or suspected contaminants (feet):
During the February 2021 assessment activities, no compounds were detected at concentrations
above the DEQ IHSB residential PSRGs (or background levels in the case of metals) in soil samples
collected at the Site.
3) Area of soil disturbed by redevelopment (square feet):
The entire Site is expected to be disturbed during grading (approximately 145,000 square feet).
Soil will be disturbed as part of leveling and grading activities to prepare the Site for construction
of the proposed apartment building and parking deck.
4) Depths of soil to be excavated (feet):
Based on review of the grading plan, cut is generally planned in the area of the parking deck
planned in the west‐central portion of the Site, and in the southern portion of the Site (3700
Ellenwood Place) for construction of an access road and dumpster enclosures. Planned cut
depths in the west‐central portion of the Site are expected to be up to approximately 10 ft bgs in
the vicinity of the proposed parking deck. Other discrete areas may include deeper excavations
for installation of deeper foundational footers, elevator banks, utility banks, etc. Soil generated
9
EMP Version 2, January 2021
during grading activities will be re‐used on‐Site as fill. Remaining portions of the Site area
planned fill areas.
5) Estimated volume of soil (cubic yards) to be excavated (attach grading plan):
Based on the grading plan and cut/fill analysis, the total volume of soil to be excavated and/or
cut is approximately 10,000 cubic yards. Copies of the most recent grading plan and cut/fill
analysis are provided in Appendix B. Excess soil generated during redevelopment of the Site will
be re‐used on‐Site as fill material.
6) Estimated volume of excavated soil (cubic yards) anticipated to be impacted by contaminants:
Based on a review of the preliminary grading plan and soil sample analytical results, it is not
anticipated that excess soil impacted by contaminants will be excavated at the Site.
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, approximately 3,500 cubic yards of
geotechnically unsuitable topsoil may be need to be transported off‐Site. Soil samples collected
in areas of geotechnically unsuitable topsoil indicate that no compounds were detected at
concentrations above the DEQ IHSB PSRGs or naturally occurring levels in the case of metals (see
Figure 3 and Table 1). Impacted or potentially impacted soil is not proposed for off‐Site disposal.
In the unlikely event potentially impacted soil is encountered and cannot be reused on‐Site as fill,
it will be sampled and managed in accordance with the procedures described in the following
sections.
Part 1.A. MANAGING ONSITE SOIL
If soil is anticipated to be excavated from the Brownfield Property, relocated on the Brownfields
Property, or otherwise disturbed during site grading or other redevelopment activities, please
provide a grading plan that clearly illustrates areas of cut and fill (approximate areas & volumes are
acceptable, if only preliminary data available).

4) Please describe the following action(s) to be taken during and following excavation and
management of site soils:
Management of fugitive dust from site
☒ Yes, describe the method will include:
Significant areas of contaminated soil are not expected to be encountered or disturbed
during future Site redevelopment activities based upon previous soil sampling data and field
screening during previous assessment activities. However, the grading contractor will take
into account conditions such as wind speed, wind direction, and moisture content of soil
during soil grading and stockpiling activities to minimize dust generation. Particular
attention will be paid by contractors to implement dust control measures as needed based
on Site and atmospheric conditions (i.e., by controlled water application, hydro‐seeding,
and/or mulch, stone, or plastic cover).
☐ No, explain rationale:
Click or tap here to enter text.
Field Screening of site soil
☒ Yes, 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 soils for
evidence of potential significantly impacted soil. Evidence of potential impacted soil
includes a distinct unnatural color, strong odor, or filled or previously disposed materials of
concerns (i.e., chemicals, tanks, drums, etc.). Should the above be noted during Site work,
Click or tap here to enter text.
12
EMP Version 2, January 2021
the contractor will contact the project environmental engineer to observe the suspect
condition. If the project environmental engineer confirms that the material may be
impacted, then the procedures below will be implemented. In addition, the environmental
engineer will contact the DEQ Brownfields Project Manager within 48‐hours to advise that
person of the condition.
☐ No, explain rationale:
Click or tap here to enter text.
Soil Sample Collection
☐ Yes, describe the sampling method (e.g., in‐situ grab, composite, stockpile, etc.):
Click or tap here to enter text.
☒ No, explain rationale:
Collection of additional soil samples is not anticipated based on results of previous Site
assessment activities. If previously unknown 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 and/or construction of the utility to continue and/or only
as far as needed to allow alternate corrective measures described below.
Suspect impacted soil excavated during grading and/or utility line installation or removal
may be stockpiled and covered in a secure area to allow construction to progress.
Suspect impacted soil will be underlain by and covered with minimum 10‐mil plastic
sheeting as shown in EMP Figure 1 included below. At least one representative soil
sample (no less than 3 aliquot soil samples) at a sample ratio of 1 soil sample per every
approximately 1,000 cubic yards of soil will be collected for the analyses selected below
(i.e., total VOCs, SVOCs, and RCRA metals plus hexavalent chromium). If the soil sample
laboratory analytical results indicate that the soil could potentially exceed toxicity
characteristic hazardous waste criteria, then the soil will also be analyzed by TCLP for
those compounds that could exceed the toxicity characteristic hazardous waste criteria.
Impacted soil will be managed in the manner described below based upon the laboratory
analyses:
i. If no organic compounds are detected in a sample (other than which are attributable
to sampling or laboratory artifacts) and metals are below the Protection of Groundwater
or Residential PSRG (whichever is lower for the detected compounds) and are consistent
with Site‐specific background levels with acceptable cumulative risk calculator results,
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 Subtitle D
landfill or permitted landfarm for petroleum impacted soil) 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 the DEQ IHSB
Residential PSRGs (other than which are attributable to sampling or laboratory artifacts
or which are consistent with Site‐specific background levels for metals), the TCLP
concentrations are below hazardous waste criteria, and cumulative risk calculator results
are acceptable, then the soil may be used on‐Site as fill without conditions.
iii. If detectable levels of compounds are found which exceed the DEQ IHSB Residential
13
EMP Version 2, January 2021
PSRGs (other than which 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, with DEQ written approval, may be used on‐Site
as fill below an impervious surface, or at least 2 ft of demonstrably clean soil. If the
impacted soil with concentrations above Residential PSRGs is moved to an on‐Site
location, its location and depth will be documented, and its location will be provided to
DEQ
iv. Impacted soil may be transported to a Brownfields approved permitted facility such
as a Municipal Subtitle D landfill or permitted landfarm for petroleum impacted soil
provided that the soil is accepted at the disposal facility. If soil is transported to a
permitted facility, the permitted facility’s written approval or acceptance to dispose of
soil from the Site will be included with the final redevelopment report. In the unlikely
event that the sample data indicates concentrations above TCLP hazardous waste
criteria, then the soil must be transported off‐Site to a permitted disposal facility that
can accept and/or treat hazardous waste.
v. Soil exported from the property may be transported to a Municipal Subtitle D
landfill provided that the soil is accepted at the disposal facility.
*Please note that should the PD elect to transport export soil to a permitted facility or to
a DEQ Brownfields pre‐approved receiving facility, soil will be direct loaded onto trucks
for transport off‐Site.

Please provide a scope of work for final grade sampling, including a diagram of soil
sampling locations, number of samples to be collected, and brief sampling methodology.
Samples should be collected from 0‐2 ft below ground surface, with the exception of VOCs
which should be taken from 1‐2 ft below ground surface. Alternatively, indicate if a work
plan for final grade sampling may be submitted under separate cover.
Following completion of soil disturbance for future Site development (i.e., after grading
and utility construction), an environmental engineer will be contracted to assess the Site
for areas that will not be covered upon completion of the redevelopment with a minimum
of 2 ft of demonstrably clean fill soil, building foundations, sidewalks, asphalt or concrete
parking areas and driveways, or other similar impervious areas (e.g., tightly spaced pavers
or bricks). If such areas exist, a Work Plan will be prepared for final grade soil sampling for
DEQ Brownfields review and approval.
Based on the current Site redevelopment plan, one final grade soil sample will be collected
for laboratory analysis for each approximately 100 ft of linear landscape area or every
approximately 1,000 sq ft of open area.

Part 1.B. IMPORTED FILL SOIL
NO SOIL MAY BE BROUGHT ONTO THE BROWNFIELDS PROPERTY WITHOUT PRIOR APPROVAL
FROM THE BROWNFIELDS PROGRAM. According to the Brownfields IR 15, “Documenting
15
EMP Version 2, January 2021
imported soil (by sampling, analysis, and reporting in accordance with review and written
approval in advance by the Brownfields Program), 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:
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 27,000 cubic
yards of fill will need to be imported to the Site to achieve final grade elevations.
3) If yes, what is the anticipated depth that fill soil will be placed at the property? (If a range
of depths, please list the range.)
In general, fill soil will be placed at depths ranging from approximately 1 ft to 13 ft (Appendix B).
4) Provide the source of fill, including: location, site history, nearby environmental concerns,
etc. Attach aerial photos, maps, historic Sanborn maps and a borrow source site history:
For import soil needed during grading activities, the procedures outlined in Part 1.B. Section 6
below will be followed to demonstrate import soil meets acceptable standards applicable to the
Site.
5) PRIOR TO ITS PLACEMENT AT THE BROWNFIELDS PROPERTY, provide a plan to analyze fill
soil to demonstrate that it meets acceptable standards applicable to the site and can be
approved for use at the Brownfields property.
The PD plans to import limited amounts of virgin organic rich topsoil from a commercial
landscape material vendor for use in proposed landscaped areas. The PD does not plan to collect
samples of landscaping materials prior to placement at the Site. In addition, the PD may use
limited amounts of lime or concrete as an amending agent for drying soil as needed during
grading and redevelopment activities. The PD does not plan to collect samples of lime or
concrete used as an amending agent prior to use at the Site.
For import soil needed during grading activities, the procedures outlined in Part 1.B. Section 7
below will be followed to demonstrate import soil meets acceptable standards applicable to the
Site.
6) Please check the applicable chemical analytes for fill soil samples. (Check all that apply):
☒ Volatile organic compounds (VOCs) by EPA Method 8260
☒ Semi‐volatile organic compounds (SVOCs) by EPA Method 8270

7) The scope of work for import fill sampling may be provided below or in a Work Plan
submitted separately for DEQ review and approval. Attach specific location maps for in‐situ
borrow sites. If using a quarry, provide information on the type of material to be brought
onto the Brownfields Property.
The PD will follow the procedures outlined below to demonstrate import soil meets acceptable
standards applicable to the Site, if necessary.
If the PD plans to import fill material from Vulcan Materials Company quarry located near
Pineville, NC, or from the Martin Marietta quarry located on Beatties Ford Road in Charlotte, NC,
no samples of the import material will be collected as adequate analytical data is available in the
DEQ Brownfields database to demonstrate material from these facilities is suitable for use as
structural fill at a Brownfields property.
If fill soil is obtained from an off‐Site property that is not a Brownfields pre‐approved quarry or is
recycled material from the Vulcan Materials Company quarry or the Martin Marietta quarries, a
sampling plan will be developed and submitted for DEQ review. DEQ approval of the sampling
plan and analytical results will be obtained prior to transporting import soil to the Site.
The specific sampling rate will be outlined in the aforementioned sampling plan. However, if the
proposed borrow source has not been previously developed (i.e., virgin land) or is a permitted
quarry that has not been pre‐approved by DEQ, soil samples will be collected for laboratory
analyses indicated above at a general rate of one per 1,000 cubic yards which will contain 3‐5
composite aliquot locations and one grab location.
Fill soil will be considered suitable for use at the Site if it does not contain compound
concentrations above DEQ IHSB Residential PSRGs, DWM Risk Calculator risk thresholds, or typical
metals concentrations which are consistent with levels identified at the Site.
Part 1.C. EXPORTED SOIL
NO SOIL MAY LEAVE THE BROWNFIELDS PROPERTY WITHOUT APPROVAL FROM THE
BROWNFIELDS PROGRAM. FAILURE TO OBTAIN APPROVAL MAY VIOLATE A BROWNFIELDS
AGREEMENT CAUSING A REOPENER OR JEOPARDIZING ELIGIBILITY IN THE PROGRAM,
ENDANGERING LIABILITY PROTECTIONS AND MAKING SAID ACTION POSSIBLY SUBJECT TO
ENFORCEMENT. JUSTIFICATIONS PROVIDED BELOW MUST BE APPROVED BY THE PROGRAM IN
17
EMP Version 2, January 2021
WRITING PRIOR TO COMPLETING TRANSPORT ACTIVITIES. Please refer to Brownfields IR 15 for
additional details.
1) If export from a Brownfields Property is anticipated, please provide details regarding the
proposed export actions. Volume of exported soil, depths, location from which soil will
be excavated on site, related sampling results, etc. Provide a site map with locations of
export and sampling results included.
As noted above, grading activities will result in net import Site. However, grading activities will
also include grubbing and stripping of organics and topsoil across the Site that likely cannot be
re‐used as fill. In the unlikely event excess soil will need to be exported from the Site, prior to
transporting off‐Site, a sampling plan will be developed and submitted to DEQ Brownfields for
review and approval. Generally, soil samples will be collected from export soil at a rate of 1
sample per every 1,000 cubic yards of export material which will include a minimum of three
combined composite locations and one grab location. Export soil sampling may be conducted in‐
situ prior to the onset of grading and an In‐Situ Soil Characterization Assessment Work Plan will
be provided to DEQ Brownfields for review and approval.
Although not anticipated based on the preliminary grading plan, should additional export be
required, the scope of work outlined above will be implemented. DEQ approval of the sampling
plan, sampling locations, and analytical results will be obtained prior to transporting export soil
from the Site. Based on analytical results of soil samples collected from the export soil, the soil
will be transported off‐Site to a suitable location. The PD will notify DEQ Brownfields of the
location receiving the export soil. If not a permitted facility, DEQ Brownfields approval and
written approval from the receiving facility will be obtained prior to transporting the soil off‐Site.
2) To what type of facility will the export Brownfields soil be sent?
☒ Subtitle D/Municipal Solid Waste Landfill (analytical program to be determined by
landfill)
☒ Permitted but Unlined Landfill (i.e. LCID, C&D, etc.) Analytical program to be
determined by the accepting Landfill;
☒ Landfarm or other treatment facility
☒ Use as fill at another suitable Brownfields Property – determination that a
site is suitable will require, at a minimum, that similar concentrations of the same or
similar contaminants already exist at both sites, use of impacted soil will not increase
the potential for risk to human health and the environment at the receiving Brownfields
property, and that a record of the acceptance of such soil from the property owner of
the receiving site is provided to Brownfields. Please provide additional details below.
☒ Use as Beneficial Fill off‐site at a non‐Brownfields Property ‐ Please provide
documentation of approval from the property owner for receipt of fill material. This will
also require approval by the DEQ Solid Waste Section. Additional information is
provided in IR 15. Please provide additional details below.
3) Additional Details: (if transfer of soil to another property is requested above, please provide
18
EMP Version 2, January 2021
details related to the proposed plans).
The environmental engineer will contact DEQ Brownfields to obtain DEQ Brownfields and DEQ
Solid Waste approval prior to exporting soil to a non‐Brownfields property or non‐permitted
disposal facility.
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 proactively install a DEQ Brownfields Program approved vapor intrusion
mitigation system during construction of the proposed apartment building. Utility corridors will
be contemplated in the Vapor Intrusion Mitigation Plan that is submitted for DEQ review and
approval.
☐ If no, include rationale here:
Click or tap here to enter text.
☐ Unknown, details to be provided in the Vapor Mitigation Plan for site buildings
Other comments regarding managing impacted soil in utility trenches:
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 concerns (i.e., chemicals, tanks, drums, etc.). Should the above be
noted during utility work, the contractor will contact the project environmental engineer to observe
the suspect condition. If the project environmental engineer confirms that the material may be
impacted, then the procedures outlined in Managing On‐Site Soil above will be implemented. In
addition, the environmental engineer will contact the DEQ Brownfields project manager within 48‐
hours to advise that person of the condition.
Should impacted soil be discovered during utility trenching activities, appropriate safety screening will
be performed to protect workers during utility installation activities. Safety screening activities
include monitoring the worker breathing zone with a calibrated photoionization detector or similar
19
EMP Version 2, January 2021
instrument at all times when in utility trenches. If safety screening results indicate further action is
warranted, the work zone will be evacuated until appropriate engineering controls (such as use of
industrial fans) are implemented.
PART 2. GROUNDWATER
1) What is the depth to groundwater at the Brownfields Property?
Depth to groundwater measurements were collected during assessment activities completed at
the Site in February 2021. The February 2021 potentiometric groundwater surface was
measured at depths ranging from approximately 7 ft bgs in lower lying areas in the southern
portion of the Brownfields property to approximately 13 ft bgs at higher elevations located in
the northern portion of the Brownfields property.
2) Is groundwater known to be contaminated by ☐onsite ☐offsite ☐both or ☒unknown
sources? Describe source(s):
Groundwater assessment at the Brownfields property included collection of four (4)
groundwater samples for laboratory analysis. Locations of the groundwater samples are shown
in Figure 3, and a tabular summary of groundwater sample laboratory analytical results is
included as Table 2. Compound concentrations are shown in Figure 4. A brief summary of the
groundwater assessment results is provided below.
Volatile Organic Compounds
Groundwater sample results indicate that trichloroethene (TCE) was detected in one
groundwater sample collected in the southern and topographically downgradient portion of the
Site (TMW‐3) at a concentration of 10.7 micrograms per liter (µg/L), which exceeds the DEQ 2L
Groundwater Quality Standards (2L Standards) and the DEQ Division of Waste Management
(DMW) Residential Vapor Intrusion Groundwater Screening Level (GWSL). The VOC acetone (up
to 33.2 µg/L), cis‐1,2‐dichloroethene (up to 0.37 J µg/L), and methyl‐tert‐butyl ether (up to 2.0
µg/L) were also detected in groundwater samples collected at the Site at concentrations above
the laboratory method detection limits, but well below the 2L Standards and the DEQ DWM
Residential Vapor Intrusion GWSLs. No other organic compounds were detected in Site
groundwater at concentrations above the DEQ 2L Standards or DEQ DWM Residential Vapor
Intrusion GWSLs.
Semi‐Volatile Organic Compounds
No SVOCs were detected at concentrations above the laboratory method detection limits in
groundwater samples collected at the Brownfields property.
Metals
Several metals were detected in Site groundwater, but at concentrations below the 2L
Standards and DEQ DWM Residential Vapor Intrusion GWSLs.
3) What is the direction of groundwater flow at the Brownfields Property?
20
EMP Version 2, January 2021
Shallow groundwater is expected to mimic surface topography which slopes generally south‐
southwest towards an unnamed tributary of Irwin Creek located approximately 1,800 feet west
of the Site (Figure 1).
4) Will groundwater likely be encountered during planned redevelopment activities?
☐Yes ☒No
If yes, describe these activities:
Shallow groundwater was encountered approximately 7 to 13 ft bgs at the Brownfields property.
Grading activities are expected to results in a net import Site and will not result in decreased
surface elevations. Proposed fill depths range from 1 to 5 ft. The deepest trenches for utility
installations are proposed for 5 ft bgs following grading. Therefore, encountering groundwater
during redevelopment activities is not anticipated at this time.
Regardless of the answer; in the event that contaminated 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).
Although not anticipated at this time, appropriate worker safety measures will be undertaken if
groundwater gathers in an open excavation within an area determined to be impacted during
construction activities. The accumulated water will be allowed to evaporate/infiltrate to the
extent time for dissipation does not disrupt the construction schedule. Should the time needed
for natural dissipation of accumulated water be deemed inadequate, an environmental
professional will be contacted and the water will be tested 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.
5) 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
6) 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 Program’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.
7) Please provide additional details as needed:
21
EMP Version 2, January 2021
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 ☐ Unknown
2) 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
4) Will workers or the public be in contact with surface water during planned redevelopment
activities? ☐ 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):
If surface water run‐off gathers in an open excavation within an area determined to be impacted
during construction activities, appropriate worker safety measures will be undertaken. The
accumulated water will be allowed to evaporate/infiltrate to the extent 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 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
PART 4. SEDIMENT
1) Are sediment sources present on the property? ☐ Yes ☒ No

☐ Yes ☐ No ☒ Unknown
In the event that contaminated soil vapor is encountered during redevelopment activities
(trenches, manways, basements or other subsurface work,) list activities for management of
such contact:
As noted above, appropriate safety screening will be performed to protect workers during sub‐
grade work including utility installation activities should potentially impacted media be
encountered. Safety screening activities include monitoring the worker breathing zone with a
calibrated photoionization detector or similar instrument. If safety screening results indicate
further action is warranted, an environmental professional will be contacted and the work zone
will be evacuated until appropriate engineering controls (such as use of industrial fans) are
H&H collected soil gas samples for laboratory analysis in February 2021. The soil gas samples were
collected within the footprint of the proposed apartment building to evaluate the potential for
structural vapor intrusion. The soil gas samples were collected from approximately 5.5 ft bgs. Soil gas
sample locations are shown in Figure 3, compound concentrations are shown in Figure 4, and a
tabular summary of the laboratory analytical data is provided in Table 3.
As shown in Table 3, the VOCs benzene (up to 22 micrograms per cubic meter [µg/m3]), chloroform
(up to 11 µg/m3), and trichloroethylene (up to 17 µg/m3) were detected in select soil gas samples at
concentrations above the DEQ DWM Residential Vapor Intrusion Soil Gas Screening Levels (SGSLs).
No other VOCs were detected at concentrations exceeding the DEQ DWM Residential SGSLs.
Hypothetical worst‐case residential use scenario risk calculator results for the soil gas to indoor air
vapor intrusion pathway did not exceed the target threshold values for cumulative carcinogenic or
noncarcinogenic risks. Although results of residential risk calculations do not exceed the target
threshold values, the PD intends to proactively install a DEQ Brownfields Program approved vapor
intrusion mitigation system designed by a North Carolina licensed Professional Engineer during
construction of the proposed apartment building.

Previous assessment activities did not include collection of sub‐slab soil gas samples within the
existing buildings. As noted above, the existing buildings will be demolished as part of the
planned assessment activities.
4) Will workers encounter contaminated sub‐slab soil vapor during planned redevelopment
activities? ☐ Yes ☐ No ☒ Unknown
☐ If no, include rationale here:
As noted above, sub‐slab soil gas samples have not been collected at the property. Based on the
groundwater and exterior soil gas sample analytical results, TCE has been detected a low
concentration above the risk‐based screening criteria in a limited area in the south‐central
portion of the Site. In the unlikely event impacted vapors are encountered, they will be managed
in accordance with the procedure outlined below.
5) In the event that contaminated soil vapor is encountered during redevelopment activities, list
activities for management of such contact
If impacted soil vapors are encountered during future redevelopment activities, worker
breathing zone will be monitored using a calibrated photoionization detector by an
environmental engineer. If results indicate further action is warranted, appropriate engineering
controls (such as use of industrial fans) will be implemented.
PART 7. INDOOR AIR
1) Are indoor air data available for the Brownfields Property? ☐ Yes ☒ No ☐ Unknown
2) 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
24
EMP Version 2, January 2021
indoor air during planned redevelopment activities? ☐ Yes ☐ No ☒ Unknown

cumulative risks, the PD intends to proactively install a DEQ Brownfields Program approved
vapor intrusion mitigation system designed by a North Carolina licensed Professional Engineer
during construction of the proposed apartment building.
VIMS Plan shall be signed and sealed by a NC Professional Engineer
If no, please provide a brief rationale as to why no vapor mitigation plan is warranted:
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.
CONTINGENCY PLAN – encountering unknown tanks, drums, or other waste materials
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.
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 include periodically screening
indoor air for volatile organic vapors with a calibrated photoionization detector when workers are
present in the Site buildings to identify potential indoor air issues. If results indicate further action is
warranted, appropriate engineering controls (such as the use of industrial fans) will be implemented.
25
EMP Version 2, January 2021
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:
☒ Volatile organic compounds (VOCs) by EPA Method 8260
☒ Semi‐volatile organic compounds (SVOCs) by EPA Method 8270

Hexavalent Chromium by EPA Method 7199
Please provide details on the proposed methods of managing the following commonly
encountered issues during redevelopment of Brownfields Properties.
During construction activities, contractors may encounter unknown sub‐surface environmental
conditions (i.e., tanks, drums, or waste materials) that if encountered, will require proper
management. Prior to beginning Site work, H&H will attend a pre‐construction kick‐off meeting
with the PD and the redevelopment contractors to discuss the DEQ approved EMP and various
scenarios when it would be appropriate and necessary to notify H&H of the discovery of unknown
subsurface features or potentially impacted media at the Site.
In the event that such conditions are encountered during Site development activities, the
environmental actions noted below will be used to direct environmental actions to be taken during
these activities and sampling data for potentially impacted soil and the disposition of impacted soil
will be provided to DEQ when the data becomes available.
Underground Storage Tanks:
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
26
EMP Version 2, January 2021
Brownfields Program. DEQ Brownfields will be notified within 48‐hours of discovery of the UST.
If a UST is encountered, the UST will be removed, if possible and the UST will be transported off‐Site
for disposal at a suitable facility. If the UST contains residual fluids, the fluids will be sampled for
VOCs, SVOCs, and RCRA metals, and transported off‐Site for disposal at a suitable facility based on
the laboratory analytical results prior to removing the UST from the ground. If a UST is encountered
that cannot be removed or does not require removal for geotechnical or construction purposes, it
may be abandoned in‐place with prior DEQ approval and construction will proceed. Where
appropriate, the bottom may be penetrated before abandonment to prevent fluid accumulation.
Impacted soil in the vicinity of the UST will be managed in accordance with the Managing On‐Site
Soil section outlined above in the EMP.
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 will 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 section outlined
above in the EMP, 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 Program 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 review the 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, and RCRA metals. Areas of suspected contaminated soil that remain at the Site after
excavation is complete above the DEQ IHSB Residential PSRGs will be managed pursuant to this
plan.
Re‐Use of Impacted Soils On‐Site:
Please refer to description outlined in the Managing On‐Site Soil section (Part 1A) of the EMP above.
If unknown, impacted soil is identified on‐site, management on‐site 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 on‐site.
If other potential contingency plans are pertinent, please provide other details or scenarios as
