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:

PART 1. Soil
1) Known or suspected contaminants in soil (list general groups of contaminants):
Twenty‐nine (29) soil samples were collected for laboratory analysis in western and eastern
portions of the Site by Partner Engineering in 2020 and 2021. Previous soil assessment activities
were conducted to evaluate the potential for impacts associated with former on‐Site operations
and to characterize soil in situ within areas proposed for cut that will generate excess soil during
grading that may not be re‐used on‐Site. A tabular summary of soil analytical data collected in
2020 and 2021 in comparison to the June 2021 North Carolina Department of Environmental
Quality (DEQ) Inactive Hazardous Sites Branch (IHSB) Preliminary Soil Remediation Goals (PSRGs)
is included as Table 1. The soil sample locations are shown in Figure 2, and compound
concentrations exceeding PSRGs are shown in Figure 3 with an overlay of the proposed
redevelopment plan. A brief summary of the soil sampling results is provided below:
Volatile Organic Compounds
Trace levels of tetrachloroethene (PCE) were detected in soil samples FCC‐1A (0.0337 milligrams
per kilogram [mg/kg]), FCC‐6 (0.0128 mg/kg), FCC‐7A (0.0091 mg/kg), and FCC‐8A (0.0068 J
mg/kg) at concentrations above the DEQ IHSB Protection of Groundwater PSRG of 0.0063 mg/kg.
The “J” flag designation indicates the compound was detected at a concentration above the
laboratory method detection limits but below the laboratory reporting limits, resulting in a
laboratory estimated concentration. A low level of benzene (0.0342 mg/kg) was detected in soil
sample FCC‐7B at a concentration above the Protection of Groundwater PSRG of 0.01 mg/kg.
Low levels of carbon tetrachloride (0.0037 J mg/kg) and naphthalene (0.446 mg/kg) were
detected in B‐8 at concentrations above the Protection of Groundwater PSRGs.
9
EMP Version 2, January 2021
In addition, low levels of 1,2,3‐trichlorobenzene, 1,2,4‐trichlorobenzene, 1,2,4‐trimethylbenzene,
1,3,5‐trimethylbenzene, acetone, chlorobenzene, ethylbenzene, toluene, xylenes, n‐
butylbenzene, n‐propylbenzene, and p‐isopropyltoluene were detected in soil samples collected
at the Site but at concentrations below the DEQ IHSB PSRGs. No other VOCs were detected at
concentrations above laboratory method detection limits in the soil samples collected at the Site.
Semi‐Volatile Organic Compounds
Laboratory analytical results indicated the presence of polycyclic aromatic hydrocarbons (PAHs)
in samples FCC‐1A, FCC‐1B, FCC‐2A, FCC‐7A, FCC‐7B, and FCC‐8A at concentrations above the
DEQ IHSB PSRGs. Analytical results in four composite samples (FCC‐1A, FCC‐1B, FCC‐7A, and FCC‐
8A) indicate the presence of benzo(a)pyrene at concentrations above the DEQ IHSB
Industrial/Commercial PSRG. Benzo(a)pyryene was detected above the DEQ IHSB Residential
PSRG in FCC‐1A, FCC‐1B, FCC‐2A, FCC‐7A, FCC‐7B, and FCC‐8A. Benzo(a)anthracene was detected
above the DEQ IHSB Residential PSRG in samples FCC‐1A, FCC‐1B, FCC‐7A and FCC‐8A.
Composite samples FCC‐1A, FCC‐1B, FCC‐7A and FCC‐8A had detections of benzo(b)fluoranthene
and indeno(1,2,3‐cd)pyrene above their respective DEQ IHSB Residential PSRGs.
Dibenzo(a,h)anthracene was also detected in FCC‐1A at an estimated concentration above the
DEQ IHSB Residential PSRG. No other SVOCs were detected above DEQ IHSB PSRGs in any other
samples collected at the Site.
Metals
Laboratory analytical results indicate that several metals were detected at concentrations above
the laboratory method detection limits. The metal arsenic (up to 11.1 mg/kg) was detected in
multiple soil samples at concentrations above the DEQ IHSB Residential PSRG of 0.68 mg/kg
and/or Commercial/Industrial PSRG of 3.0 mg/kg.
Hexavalent chromium (up to 2.43 mg/kg) was detected at concentrations above the DEQ IHSB
Residential PSRG of 0.31 mg/kg in soil samples FCC‐1A, FCC‐1B, FCC‐2A, FCC‐4A, FCC‐4B, FCC‐5A,
FCC‐5B, FCC‐6, FCC‐7A, FCC‐8A, FCC‐8B, FCC‐9, B‐8, B‐9, and B‐10. Selenium (up to 2.7 mg/kg)
was detected in samples FCC‐4A, B‐1*, B‐2*, and B‐3* at concentrations above the Residential
and/or Protection of Groundwater PSRGs.
Lead (703 mg/kg) and cadmium (4.6 mg/kg) were detected in soil sample FCC‐6 (4‐8) at
concentrations above the Protection of Groundwater and/or Residential PSRGs. It is of note that
evaluation area FCC‐6 is an area proposed for placement of fill and is not planned for disturbance
during grading activities.
Additional metals, including barium, trivalent chromium, lead, mercury, and silver, were
detected in soil samples collected at the Site at concentrations below the DEQ IHSB PSRGs and
consistent with published background levels for North Carolina soils.
It is of note that metals concentrations detected in soil samples collected in areas of planned cut
appear to be generally consistent with naturally occurring levels with the exception of lead
10
EMP Version 2, January 2021
concentrations detected in FCC‐1A (114 mg/kg) and FCC‐2A (190 mg/kg).
2) Depth of known or suspected contaminants (feet):
As noted above, select VOCs, metals, and/or PAHs were detected at concentrations above the
DEQ IHSB PSRGs in composite soil samples FCC‐1A (3‐10 ft bgs), FCC‐1B (12‐16 ft bgs), FCC‐2A (5‐
10 ft bgs), FCC‐7A (2‐4 ft bgs), and FCC‐8A (0‐5) and soil borings B‐2 (10 ft bgs), B‐8 (6 ft bgs), and
B‐9 (4 ft bgs). In addition, select metals are present at levels above PSRGs in soil samples FCC‐4A
(4‐10 ft bgs), FCC‐4B (10‐14 ft bgs), FCC‐5A (5‐8 ft bgs), FCC‐5B (8‐13 ft bgs), FCC‐6 (4‐8 ft bgs),
FCC‐7A (2‐4 ft bgs), FCC‐8B (6‐8 ft bgs), B‐1* (8 ft bgs), B‐2* (8 ft bgs), B‐3* (8 ft bgs), and B‐10 (4
ft bgs).
As noted above, soil characterization area FCC‐6 is proposed for placement of fill. Soil
characterization section FCC‐7 is also proposed for placement of fill with the exception of a small
area with higher elevations that will be leveled. Soil in characterization sections FCC‐6 and FCC‐7
are planned to remain in place.
3) Area of soil disturbed by redevelopment (square feet):
Based on the preliminary grading plans and cut‐fill analysis (Appendix B), the majority of the Site
is expected to be cleared and graded (approximately 465,400 square feet) to level the Site for
redevelopment. A copy of the preliminary grading plan and cut‐fill analysis is provided as
Appendix B.
4) Depths of soil to be excavated (feet):
Based on review of the cut‐fill analysis, planned cut depths are expected to range from 1 to 4 ft
bgs on the western Site parcel for installation of paved parking areas near the existing Site
building. Review of the cut‐fill analysis prepared for the eastern Site parcels indicates that
planned cut depths are expected to range from approximately 1 to 18 ft bgs in the vicinity of the
proposed apartment buildings. Other discrete areas may include deeper excavations for
installation of deeper foundational footers, elevator banks, utility banks, etc. Remaining portions
of the Site are planned for fill to achieve final grade elevations.
5) Estimated volume of soil (cubic yards) to be excavated (attach grading plan):
Cut‐fill analysis and calculations indicate that the total volume of soil to be excavated and/or cut
from the eastern Site parcels is approximately 21,400 cubic yards. The western portion of the
Site will require approximately 2,500 cubic yards to reach final grade elevations. Soil generated
during grading on the eastern Site parcels will be used on‐Site as fill on the western Site parcel.
In addition to grading, limited excavations for installation of new utilities will be completed
during redevelopment of the Site.
6) Estimated volume of excavated soil (cubic yards) anticipated to be impacted by contaminants:
Based on a review of the preliminary grading plan and results of in situ soil characterizations
assessment activities, approximately 18,000 cubic yards of excavated soil will contain
11
EMP Version 2, January 2021
compounds at concentrations above the DEQ IHSB PSRGs.
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 21,400 cubic yards of excess soil
may need to be transported off‐Site. In‐situ soil sampling results identified PAHs at
concentrations above the DEQ IHSB Commercial/Industrial PSRGs in soil characterization areas
FCC‐1, FCC‐6, FCC‐7A, and FCC‐8A. In‐situ soil sampling results identified PAHs at concentrations
above the DEQ IHSB Residential and/or Protection of Groundwater PSRGs in soil characterization
areas FCC‐2A and FCC‐7B. Sampling results identified select metals at concentrations above the
DEQ IHSB Protection of Groundwater and/or Residential PSRGs but within naturally occurring
background concentrations in evaluation areas FCC‐4, FCC‐5, FCC‐8B, and FCC‐9. No other
compounds were detected at concentrations above the DEQ IHSB PSRGs or background levels in
the case of metals in areas of planned cut that will generate excess soil.
If 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).
1) HAZARDOUS WASTE DETERMINATION:
a) Does the soil contain a LISTED WASTE as defined in the North Carolina Hazardous
Waste Section under 40 CFR Part 261.31‐261.35?....................................... ☐Yes ☒No
☐ If yes, explain why below, including the level of knowledge regarding processes
generating the waste (include pertinent analytical results as needed).
Click or tap here to enter text.
☐ If yes, do the soils exceed the “Contained‐Out” levels in Attachment 1 of the
North Carolina Contained‐In Policy?................................................. ☐ Yes ☒ No
b) NOTE: IF SOIL MEETS THE DEFINITION OF A LISTED HAZARDOUS WASTE AND EXCEEDS
THE CONTAINED‐OUT LEVELS IN ATTACHMENT 1 TO THE NORTH CAROLINA
CONTAINED‐IN POLICY THE SOIL MAY NOT BE RE‐USED ON SITE AND MUST BE
DISPOSED OF IN ACCORDANCE WITH DEQ HAZARDOUS WASTE SECTION RULES AND
REGULATIONS.
c) Does the soil contain a CHARACTERISTIC WASTE?.................................... ☐ Yes ☒ No

☐ Rule of 20 results (20 times total analytical results for an individual
hazardous constituent on TCLP list cannot, by test method, exceed regulatory
TCLP standard)
Click or tap here to enter text.
☒ If no, explain rationale:
Lead was detected in samples FCC‐1A, FCC‐2A, FCC‐6, FCC‐7B at concentrations
greater than 100 mg/kg. Partner requested that the lab analyze soil samples
FCC‐1A, FCC‐2, and FCC‐6 for TCLP lead. Partner also requested that the lab
analyze soil samples FCC‐1A for TCLP chromium. Results of analysis indicate that
chromium and lead were not detected at concentrations above the EPA
Maximum Allowable Concentrations of 5 mg/L in any of the soil samples. Based
on results of soil assessment activities and TCLP lead and chromium analyses, no
compounds have been identified at characteristically hazardous levels. In
addition, evaluation area FCC‐6 and FCC‐7 (aside from one area of higher
elevation) are proposed for placement of fill and soils in these areas are not
likely to be significantly disturbed during future grading.
Laboratory analytical results for soil samples FCC‐8B (6‐8’), B‐2 (10’), B‐3 (8’), B‐
3* (8’), and B‐7 (13’) indicated the presence of total chromium at concentrations
above the TCLP criteria using the Rule of 20.
Deepest cut depths in soil characterization section FCC‐8 are expected to be
approximately 4 to 5 ft. Therefore, deeper soil with total chromium
concentrations above 100 mg/kg within this section are not planned for
disturbance. Soil samples B‐3, B‐3*, and B‐7 were collected in areas planned for
placement of fill and deeper soil with total chromium concentrations above 100
mg/kg in these areas are not planned for disturbance.

EMP Version 2, January 2021
Management of fugitive dust from site
☒ Yes, describe the method will include:
Areas of significantly 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 and/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
concern (i.e., chemicals, tanks, drums, etc.). Should the above be noted during Site work,
the contractor will contact Hart & Hickman to report that the material may be impacted
and the procedures outlined below will be implemented. In addition, Hart & Hickman 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. 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
15
EMP Version 2, January 2021
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 subtitle D
municipal solid waste (MSW) landfill) 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 do not exceed the DEQ IHSB
Industrial/Commercial 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 the 2213 and/or 2320
Toomey Avenue parcels as fill without conditions and will not be considered as
import/export.
iv. If detectable levels of compounds are found which exceed the DEQ IHSB
Residential 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 as fill on the multi‐family parcels below an impervious surface, or at least 2 ft of
documented compacted clean soil. If the impacted soil with concentrations above
Residential PSRGs is moved to a location on the multi‐family portion of the Site, its
location and depth will be documented, and its location will be provided to DEQ
v. If detectable levels of compounds are found which exceed the DEQ IHSB
Industrial/Commercial 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 as fill for the multi‐family parking areas, or on the 2213 Toomey
Avenue parcel and/or 2320 Toomey Avenue parcels below an impervious surface, or at
least 2 ft of documented compacted clean soil. If the impacted soil with concentrations
above Industrial/Commercial PSRGs is moved to an on‐Site location, its location and
depth will be documented provided to DEQ
vi. Impacted soil may be transported to a Brownfields approved permitted facility
such as a landfill or landfarm 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
16
EMP Version 2, January 2021
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 or treat hazardous waste.
*Please note that should the PD elect to transport export soil to a MSW landfill 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 installations), Hart & Hickman will 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. If no such areas exist, documentation will
be provided to the DEQ Brownfields project manager and/or the DEQ Brownfields
Property Management Unit. Final grade soil samples will consist of a maximum of five (5)
aliquot soil samples collected from within each evaluation area which will be combined
and homogenized to form one composite soil sample representative of that evaluation
area and submitted for analysis of SVOCs and RCRA metals plus hexavalent chromium. In
addition, one grab soil sample will be collected for each evaluation area and submitted for
laboratory analysis of VOCs.

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
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.”

EMP Version 2, January 2021
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 2,500 cubic
yards of fill will need to be imported to the western Site parcel to achieve final grade elevations.
Excess soil generated during grading on the eastern Site parcels will be used as fill on the western
Site parcel, as needed.
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 areas associated with the proposed redevelopment are located on the western Site
parcel, the northeastern and southwestern portions of the eastern Site parcels, and along Toomey
Avenue (Appendix B). The thickness of the fill ranges from approximately 1 ft to 4 ft on the
western Site parcel, approximately 1 ft to 8 ft in the northeastern portion of the eastern Site
parcels, approximately 1 to 6 ft in the southwestern portion of the eastern Site parcels, and up to
approximately 1 ft along Toomey Avenue.
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, soil generated in areas planned for cut will be
used to reach final grade elevations. In the unlikely event that additional import soil is needed,
the procedures outlined in Part 1.B. Section 7 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 cement 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):

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 the 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, 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), 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. If the proposed borrow
source is a permitted quarry that has not been pre‐approved by DEQ Brownfields (e.g., Martin
Marietta quarry located on Arrowood Road in Charlotte, NC), one composite soil sample
consisting of 3‐5 composite aliquot locations and one grab location will be collected for the
laboratory analyses indicated above.
Fill soil will be considered suitable for use on multi‐family portions of the Site if it does not contain
compound concentrations above DEQ IHSB Residential PSRGs, and DWM Risk Calculator risk
thresholds, or typical metals concentrations which are consistent with levels identified in the Site
area. Fill soil will be considered suitable for use on the 2213 and 2320 Toomey Avenue portions
of the Site if it does not contain compound concentrations above DEQ IHSB Industrial/Commercial
20
EMP Version 2, January 2021
PSRGs, and DWM Risk Calculator risk thresholds, or typical metals concentrations which are
consistent with levels identified in the Site area.
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
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.
Based on review of the grading plan and cut‐fill analysis, up to approximately 18,900 cubic yards
of soil may need to be transported off‐Site (includes using approximately 2,500 cubic yards of
excess soil for fill on the western Site parcel). Partner completed in‐situ soil characterization
sampling in areas of planned cut where excess soil will be generated that may not be re‐used on‐
Site as fill. In situ soil characterization sampling was completed in accordance with the DEQ‐
approved Brownfields Assessment Work Plan dated June 9, 2021. The assessment included
collection of sixteen (16) soil samples for laboratory analysis (FCC‐1 through FCC‐9) from nine (9)
evaluation areas to identify areas of planned cut at the Site that do not have compound
concentrations in soil above DEQ IHSB PSRGs so that soil can be direct loaded onto trucks and
transported off‐Site during grading activities. Soil characterization sections planned for cut
include FCC‐1 through FCC‐5 and FCC‐8. Soil characterization sections planned for placement of
fill include FCC‐6, FCC‐7 (with the exception of one small area that will be leveled), and FCC‐9.
In‐situ soil sampling results identified compounds at concentrations above the DEQ PSRGs (and
background levels in the case of metals) in soil characterization sections FCC‐1, FCC‐2A (shallow
soil from 5‐10 ft bgs), FCC‐7A, FCC‐7B (shallow soil from 2‐8 ft bgs), and FCC 8A (shallow soil from
0‐5 ft bgs). No compounds were detected at concentrations above the DEQ IHSB PSRGs or
background levels in the case of metals within in situ soil characterization sections FCC‐2B
(deeper soil from 12‐18 ft bgs), FCC‐3, FCC‐4, FCC‐5, or FCC‐8B (deeper soil from 6‐8 ft bgs). The
locations of in situ soil samples and in situ soil characterization sections are shown in Figure 3,
and a tabular summary of the in‐situ soil sample analytical results is included as Table 1.
Export soil generated during grading within in situ soil characterization section FCC‐1, FCC‐2A,
and FCC‐8A will be re‐used on‐Site as fill (where possible) and placed beneath at least 24 inches
of clean fill or an impervious cap, transported to a Municipal Solid Waste landfill such as the
21
EMP Version 2, January 2021
Republic Services facility in Concord, NC, or with DEQ prior written approval, to another
Brownfields property in need of import soil. Written approval from the receiving facility will be
obtained and provided to DEQ prior to transporting the soil off‐Site.
Export soil generated during grading within in situ soil characterization sections FCC‐2B (deeper
soil from 12‐18 ft bgs), FCC‐3, FCC‐4, FCC‐5, FCC‐8B (deeper soil from 6‐8 ft bgs), and FCC‐9 will
be direct loaded and transported to the Old 27 LCID Landfill, or with DEQ prior written approval,
other LCID and Construction & Demolition (C&D) landfills with similar background metals
concentrations, or to other Brownfields property(s) in need of import soil. A tabular summary
of metals concentrations detected in soil characterization sections in comparison to background
metals concentrations detected in soil samples collected at the Old 27 LCID landfill facility is
provided in Appendix C and a summary of soil management options for soil characterization
areas are provided in Appendix D.
In situ soil characterization sampling completed at the Brownfields property in June 2021 did
not include soil characterization sampling of shallow (0‐5 ft bgs) soil in characterization areas
FCC‐1, FCC‐2, FCC‐3, FCC‐4, and FCC‐8. Shallow soil from these characterization areas will be re‐
used on Site as fill, if possible.
Should additional export be required outside of the in situ soil characterization sections or if
shallow soil from sections FCC‐1, FCC‐2, FCC‐3, FCC‐4, and FCC‐8 cannot be reused on‐Site as fill,
the following sampling plan will be implemented. Prior to transporting the soil 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 one 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 for
review and approval.
DEQ approval of the sampling plan, sampling locations, and analytical results will be obtained
prior to transporting the additional 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
22
EMP Version 2, January 2021
☒ 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
details related to the proposed plans).
As noted above, prior to exporting additional soil not characterized as part of in situ soil
sampling completed in June 2021 and described above, Hart & Hickman 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 install a methane and vapor intrusion mitigation system (VIMS) during
construction of the multi‐family buildings. As part of the VIMS design, the locations of sub‐grade
utilities will be evaluated to confirm that that the proposed VIMS will effectively minimize
potential vapor intrusion. The Vapor Intrusion Mitigation Plan will be submitted under separate
cover.
The PD does not plan to install a VIMS in the existing buildings located at 2213 and 2320 Toomey
Avenue at this time. Additional vapor intrusion assessment is planned for the 2213 Toomey
Avenue building and results will be provided under separate cover.
☐ If no, include rationale here:
23
EMP Version 2, January 2021
☐ 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 Hart & Hickman to observe the suspect
condition. If Hart & Hickman confirms that the material may be impacted, then the procedures
outlined in Managing On‐Site Soil above will be implemented. In addition, Hart & Hickman 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
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?
During groundwater assessment activities completed at the Site, the depth to groundwater was
measured at a depth ranging from approximately 10 ft bgs in lower lying areas to approximately
25 ft bgs at higher elevations.
2) Is groundwater known to be contaminated by ☐onsite ☐offsite ☒both or ☐unknown
sources? Describe source(s):
Previous groundwater assessment at the Brownfields property included collection of eleven (11)
groundwater samples for laboratory analysis. The most recent groundwater assessment at the
Brownfields property included collection of four (4) groundwater samples from on‐Site
permanent monitoring wells for laboratory analysis. Locations of previous groundwater samples
are shown in Figure 2. A tabular summary of groundwater sample laboratory analytical results is
included as Table 2. Compound concentrations exceeding DEQ NCAC 15A 2L Groundwater
Quality Standards (2L Standards) and/or the DEQ Division of Waste Management (DWM) Vapor
Intrusion Groundwater Screening Levels (GWSLs) are shown in Figure 4. Aside from select metals
which appear to be affected with high bias due to elevated turbidity, no compounds have been
detected in groundwater samples collected at the Site at concentrations above the DEQ 2L
Standards or DEQ DWM Vapor Intrusion GWSLs. A brief summary of the groundwater
assessment results is provided below.
Volatile Organic Compounds
The VOCs acetone, 2‐butanone, chloromethane, ethylbenzene, 2‐hexanone, naphthalene,
toluene, and xylenes were detected in groundwater samples collected at the Site at
concentrations above the laboratory method detection limits, but well below the 2L Standards
24
EMP Version 2, January 2021
and the DEQ DWM Vapor Intrusion GWSLs.
Semi‐Volatile Organic Compounds
The SVOCs acenaphthene, benzyl alcohol, fluoranthene, fluorene, 1‐methylnaphthalene, 2‐
methylnaphthalene, naphthalene, phenanthrene, and pyrene were 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 Vapor Intrusion GWSLs. No other organic
compounds were detected in Site groundwater at concentrations above the laboratory method
detection limits.
Metals
During assessment activities conducted in 2020 and 2021, groundwater sample results indicate
that total chromium (up to 58.0 µg/L) and lead (up to 18.3 µg/L) were detected in groundwater
at the Site at concentrations above the 2L Standards of 10 µg/L and 15 µg/L, respectively.
Groundwater analytical results also indicate that arsenic, barium, cadmium, and hexavalent
chromium were detected at concentrations above the laboratory method detection limits but
below the 2L Standards.
It is of note that the environmental reports prepared for the Site indicate high turbidity in the
groundwater samples collected at the Site and elevated metals concentrations may be attributed
to high turbidity. Laboratory analytical results for filtered groundwater samples collected at the
Site in December 2020 did not detect dissolved concentrations of lead above the 2L Standards.
3) What is the direction of groundwater flow at the Brownfields Property?
Shallow groundwater is expected to mimic surface topography which slopes generally northwest
and northeast toward a tributary of Little Sugar Creek generally located along the northwestern
and northeastern Site boundaries (Figure 1).
4) Will groundwater likely be encountered during planned redevelopment activities?
☐Yes ☒No
If yes, describe these activities:
Shallow groundwater was encountered approximately 10 to 12 ft bgs during recent groundwater
assessment activities conducted in the western portions of the Brownfields property. Grading
activities in the western portion of the Site are expected to result in a net import and will not
result in decreased surface elevations in areas where shallow groundwater may be encountered.
Proposed fill depths range from 1 to 3 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.
Shallow groundwater was encountered approximately 5 to 24 ft bgs during groundwater
assessment activities conducted in the eastern portions of the Brownfields property. Shallow
groundwater may be encountered during grading and utility installation activities in this portion
of the Site. If groundwater is encountered during redevelopment activities, the procedures

management of groundwater (e.g., dewatering of groundwater from excavations or
foundations, containerizing, offsite disposal, discharge to sanitary sewer, NPDES permit, or
sampling procedures).
Based on previous assessment activities, contractors will be made aware of areas at the Site
where groundwater may be impacted and Hart & Hickman will be contacted to conduct safety
screening if groundwater is encountered in these predetermined areas. Should groundwater
be encountered outside of areas on known impacts, the contractors will contact Hart &
Hickman to observe conditions to determine if there are impacts that may pose a potential risk
to workers. 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, the water will be tested and
disposed off‐Site (if impacted), or tested and discharged to the stormwater retention systems
(if not impacted above DEQ surface water quality standards) in accordance with applicable
municipal and State regulations for erosion control and construction stormwater control.

eastern Site parcels. The intermittent stream is an unnamed tributary of Irwin Creek.
Redevelopment activities include diverting a portion of the stream through a culvert and
improving a portion that will remain exposed in the surface parking area of the proposed
redevelopment.
When excavating during construction activities at the Site, the workers or contractors will
observe soils for evidence of potential significantly impacted soil. Evidence of potential
significantly 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 excavation work, the contractor will contact Hart & Hickman to observe the suspect
condition. If Hart & Hickman confirms that the material may be impacted, then safety screening
will be conducted during work in this area.
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.

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.
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

EMP Version 2, January 2021
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 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
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. DEQ UST Program protocol (or other protocol approved in
advance by the DEQ Brownfields Program) will be followed for UST abandonment procedures.
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.
32
EMP Version 2, January 2021
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 Hart & Hickman. Hart & Hickman will screen materials using a
calibrated photoionization detector and Landtec GEM 5000® meter 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 applicable DEQ IHSB
Residential PSRGs will be managed pursuant to this plan.
If significant buried organic material or buried waste material that has the potential to produce
methane (i.e., wood, trash, etc.) is encountered during redevelopment activities, the Brownfields
program will be notified to discuss whether assessment for potential landfill gas accumulation is
warranted.
Re‐Use of Impacted Soils On‐Site:
Please refer to the 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
needed below:
