EMP Version 2, January 2021
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: Click or tap here to enter
text.
2. Estimated jobs created:
a. Construction Jobs: Approximately 400-500 jobs will be created during the redevelopment construction process.
b. Full Time Post-Redevelopment Jobs: Approximately 100 full time jobs will
be created at the post-redevelopment facility.

PART 1. Soil
1) Known or suspected contaminants in soil (list general groups of contaminants):
Operations at the Site consisted of 1) vanadium catalyst manufacturing from 1965 to 1972, 2)
solvent recovery, reclamation, and blending from 1974 to 1984, 3) bulk chemical repackaging
from 1974 to 1976, and 4) laboratory services and chromium compound manufacturing from

8
EMP Version 2, January 2021
1977 to 1988, and was vacant thereafter. In the early 1990s, soil contamination was identified at
the Site and subsequently listed as a North Carolina Inactive Hazardous Site (Aquair Corporation
Site, NCD074511361). In 1999, stabilization measures were conducted at the Site including the
removal of vanadium pellets, debris and a septic tank system. The on-Site buildings were
demolished in approximately 2000. Soil samples collected from 1990 through 2003 indicate
metals and chlorinated solvent compounds are the primary constituents of interest in soil.
Historical and more recent soil and sediment analytical data is provided in Table 1. A Site Plan
depicting historical features and soil and sediment sample locations are provided as Figure 2 and
3, respectively.

A Brownfields agreement was executed for the Site in July 2015. The Brownfields Plat depicts an
“Area of Possible Soil Contamination” and the agreement notes that an EMP must be prepared
and approved prior to soil disturbance activities in the Area of Possible Soil Contamination. In
December 2015, Terracon, on behalf of a potential purchaser of the Site, conducted soil sampling
in the area designated on the Brownfields Plat as the Area of Possible Soil Contamination. A total
of 13 surface soil samples were collected to represent this area. Additionally, four samples were
collected from borings advanced as soil vapor sample points, west of the Area of Possible Soil
Contamination. The sample locations and depths were chosen specifically to evaluate potential
impacts associated with potential redevelopment of the Site.

Site plans depicting 1) the proposed Site redevelopment 2) the locations of historical and more
recent soil sample locations depicted by consultant and date, and 3) the locations of historical and
more recent soil and sediment sample locations with concentrations above screening levels are
provided as Figures 3 through 5, respectively. Soil analytical data is summarized in Table 1.

Volatile Organic Compounds (VOCs): The results of historical soil samples indicate that several
VOCs (carbon tetrachloride, chloroform, tetrachloroethene, 1,1,2,2-tetrachloroethane, and
trichloroethene) were detected above DEQ Inactive Hazardous Sites Branch (IHSB) June 2021
Industrial/Commercial Preliminary Soil Remediation Goals (PSRGs) at depths below 1 foot below
ground surface (ft bgs) to 12 ft bgs. The 2015 surface soil samples (0-0.5 ft) had low level
detections of VOCs which were below the Industrial/Commercial PSRGs.

Semi-Volatile Organic Compounds (SVOCs):
The results of a single historical soil sample analyzed for SVOCs (SS-03) contained concentrations
of SVOCs above the laboratory reporting limit (RL) but below the June 2021 Industrial/Commercial
PSRGs, with the exception of 1,2,4-Trichlorobenzene which contained a duplicate sample slightly
above the Industrial/Commercial PSRG. The 2015 surface soil samples did not contain
concentrations of SVOCs above the RL.

Metals:
Cadmium, total chromium, lead, and mercury were detected in several historical shallow soil
samples at concentrations above the June 2021 Industrial/Commercial PSRG and regional
background levels. Vanadium was also detected in 1992 soil sample S-3 (1 ft) at a concentration
exceeding the June 2021 Industrial/Commercial PSRG and regional background levels.

9
EMP Version 2, January 2021
Depth of known or suspected contaminants (feet):
In general, historical soil samples were collected from 0-1 ft bgs. In 2003, five deeper soil boring
were installed and several compounds (carbon tetrachloride, chloroform, tetrachloroethene, and
trichloroethene) were detected above Commercial/Industrial PSRGs in two soil samples (APH-42
and APH-59) collected from 6.0-6.5 ft bgs. Soil samples from the 2015 soil sampling event were
collected from 0-0.5 ft bgs. 2) Area of soil disturbed by redevelopment (square feet):
Grading will generally be completed across most of the Site for redevelopment prior to the start
of construction (approximately 2,900,000 sq ft or 65 acres).

3) Depths of soil to be excavated (feet):
Based on review of the preliminary cut-fill analysis and grading plan, deeper cut, up to
approximately 12 feet, is proposed in the southern portion of the Site. The cut-fill map and
grading plan are included as Appendix C. Any soil not placed under impervious surface or used
as part of final grade will be wasted in the spoil mounds depicted along the Site boundaries. The
soil mounds are not included on the cut-fill plan as the engineered final grade is not yet known in
those locations.

4) Estimated volume of soil (cubic yards) to be excavated (attach grading plan):
Based on the cut-fill analysis, approximately 250,000 cubic yards of soil will be cut and filled at
the Site with no net import or export expected.

5) Estimated volume of excavated soil (cubic yards) anticipated to be impacted by contaminants:
Any net excavated soil will remain on Site due to the net balance of soil.

6) Estimated volume of contaminated soil expected to be disposed of offsite, if applicable:
No soil is expected to be disposed off-Site as the grading plan results in a net balance cut/fill.

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).
Note that vanadium pentoxide pellets were reportedly removed from the Site in
1999 which could be considered a hazardous waste if excavated. The pellets

10
EMP Version 2, January 2021
were located in the Area of Potential Soil Contamination which is an area of
expected fill. Therefore, it is unlikely that vanadium pellets, if present, will be
excavated. If potential vanadium pentoxide pellets are identified during soil
excavation/grading, the soil containing the pellets will be segregated, placed in
a covered roll-off box, and managed in coordination with the DEQ Hazardous
Waste Section.

☐ 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
☐ If yes, mark reason(s) why below (and include pertinent analytical results).
☐ Ignitability Click or tap here to enter text.
☐ Corrosivity Click or tap here to enter text.
☐ Reactivity Click or tap here to enter text.
☐ Toxicity Click or tap here to enter text.
☐ TCLP results Click or tap here to enter text.
☒ 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)
The potential for hazardous waste exists because several total chlorinated
VOCs, total lead, and total mercury concentrations in soil exceeded 20
times the toxicity characteristic leaching procedure (TCLP) “rule of thumb”
(Table 1); however, these soil samples were not analyzed by TCLP methods.
Impacted soil is located in a portion of the Site that will be a net fill area,
and export is not expected to be generated from the Site.

If soils are disturbed during grading which are suspected to contain
concentrations above toxicity characteristic hazardous waste criteria (based
on visual observations or field screening with a calibrated photoionization
detector [PID]), the soil will be sampled and managed in accordance with
the procedures outlined below.

☐ If no, explain rationale:

EMP Version 2, January 2021
d) NOTE: IF SOIL MEETS THE DEFINITION OF A CHARACTERISTIC HAZARDOUS WASTE, THE
SOIL MAY NOT BE RE-USED ON SITE AND MUST BE DISPOSED OF IN ACCORDANCE
WITH DEQ HAZARDOUS WASTE SECTION RULES AND REGULATIONS.
2) Screening criteria by which soil disposition decisions will be made (e.g., left in place, capped in
place with low permeability barrier, removed to onsite location and capped, removed offsite):
☐ Preliminary Health-Based Residential SRGs
☒ Preliminary Health-Based Industrial/Commercial SRGs

3) If known impacted soil is proposed to be reused within the Brownfields Property Boundary,
please check the measures that will be utilized to ensure safe placement and documentation of
same. Please attach a proposed location diagram/site map.
☒ Provide documentation of analytical report(s) to Brownfields Project Manager
☒ Provide documentation of final location, thickness and depth of relocated soil on site map
to Brownfields Project Manager once known
☐ Geotextile to mark depth of fill material.
Provide description of material:
Click or tap here to enter text.
☒ Manage soil under impervious cap ☒ or clean fill ☒
☒ Describe cap or fill:
In the unlikely event that impacted soil is excavated and relocated at the Site, the soils
which are disturbed will be placed within the Area of Possible Soil Contamination and/or
covered by impervious surfaces such as paved areas or building slabs, creating a cap over
potentially impacted soils (Figure 3). If potentially impacted disturbed soil is placed outside
of the Area of Possible Soil Contamination, the soil will be sampled with GPS coordinated
determined and, if compounds are detected above Industrial/Commercial PSRGs, the soil
will subsequently be covered with at least two feet of clean fill or under impervious surface
and DEQ will be contacted to about the need to amend the Brownfields Plat.
☒ Confer with NC BF Project Manager if Brownfield Plat must be revised (or re-recorded if
actions are Post-Recordation).
☒ GPS the location and provide site map with final location.

12
EMP Version 2, January 2021
☐ Other. Please provide a description of the measure:

4) Please describe the following action(s) to be taken during and following excavation and
management of site soils:
Management of fugitive dust from site
☒ Yes, describe the method will include:
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). Potentially impacted soil
will be managed as described below.

☐ 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 significantly
impacted soil includes a distinct unnatural color, strong odor, or filled or previously
disposed materials of concerns (i.e., chemicals, tanks, drums, pellets, etc.). Should the
above be noted during Site 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 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:
Soil samples have been collected from within the Area of Potential Soil Contamination,
including samples collected specifically to support the Brownfields Agreement. Based on
the grading plan, soil within the Area of Possible Soil Contamination is not planned for
excavation, but is a fill area.

In the unlikely event unknown significant soil impact is encountered during grading

EMP Version 2, January 2021
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 significantly 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 the Figure
on the final page of the EMP form below. At least one representative composite soil
sample (consisting of no less than 3 aliquot soil samples) at a sample ratio of 1 composite
soil sample per every approximately 1,000 cubic yards of soil will be collected for analysis
of total VOCs, SVOCs, and RCRA metals plus copper, nickel, vanadium, zinc, and
hexavalent chromium (note the VOC sample will be a grab sample from one aliquot soil
sample). If the results of analysis of the sample indicate that the soil could potentially
exceed toxicity characteristic hazardous waste criteria, then the soil will also be analyzed
by TCLP methods 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, 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) along with receiving facility written
approval for acceptance of the soil will be provided to DEQ for approval prior to
transporting soil off-Site.
ii. If detectable levels of compounds are found which do not exceed the DEQ IHSB
Industrial PSRGs (other than which are attributable to sampling or laboratory artifacts or
which are consistent with Site-specific background levels for metals) and the TCLP
concentrations are below hazardous waste criteria, then the soil may be used on-Site as
fill without conditions.
iii. If detectable levels of compounds are found which exceed the 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 on-Site as fill below an impervious surface, or at least 2 ft of
verified compacted clean soil. If the impacted soil with concentrations above
Industrial/Commercial PSRGs is moved to an on-Site location other than the Area of
Possible Soil Contamination on the Brownfields plat, its location and depth will be
documented, and its location will be provided to DEQ.
iv. Impacted soil may be transported to a permitted facility such as a landfill or
landfarm provided that the soil is accepted at the disposal facility. DEQ Brownfields, and

14
EMP Version 2, January 2021
when appropriate the DEQ Soil Waste Section, program approval will be requested for
potential export to an off-Site facility other than a Subtitle D lined facility. If soil is
transported to a permitted facility, permitted facility written approval to dispose of soil
from the Site will be included with the final redevelopment report.
v. 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 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 the Site development (i.e., after grading and
utility construction), Hart & Hickman will observe the Site for disturbed areas that will not
be covered 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 0-2 ft 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 copper, nickel, vanadium, zinc,
and 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

16
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 the cut-fill plan, no soil will be imported. The cut-fill analysis includes material other
than soil including gravel and aggregate, and based on the grading plan the projected import
volume will solely include gravel and aggregate.

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.)
Not Applicable

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:
If import soil is needed, the PD plans to import virgin fill material from known quarry (i.e., Vulcan
Materials Company quarry located near Pineville, NC, Martin Marietta quarry located on Beatties
Ford Road in Charlotte, NC, or Martin Marietta quarry located on Arrowood Road in Charlotte,
NC). Alternatively, if the PD elects to not import soil from a known quarry, upon determination of
the borrow source, DEQ will be notified and the procedures outlined below will be implemented

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.

If soil is imported from quarry that has been pre-approved for import to Brownfields properties
(as identified above), soil samples will not be collected prior to placement on Site. For import
soil needed during grading that is sourced from an unapproved borrow site, the procedures
outlined 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

17
EMP Version 2, January 2021
☒ Semi-volatile organic compounds (SVOCs) by EPA Method 8270
☒ Metals RCRA List (8) (arsenic, barium, cadmium, chromium, mercury, lead, selenium and silver): Specify Analytical Method Number(s): Plus copper, nickel, vanadium, and zinc by EPA Method 6020/7471
☐ Pesticides: Specify Analytical Method Number(s): Click or tap here to enter text.
☐ PCBs: Specify Analytical Method Number(s): Click or tap here to enter text.
☒ Other Constituents & Respective Analytical Method(s) (i.e. Hexavalent Chromium, Herbicides, etc.): Hexavalent Chromium by EPA Method 7199

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 that is not from a
Brownfields-approved fill soil location meets acceptable levels applicable to the Site.

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. If
the borrow source property has been previously developed, soil samples will be collected for
laboratory analyses indicated above at a general rate of approximately one per 500 cubic yards.

Fill soil will be considered suitable for transport to the Site if it does not contain compound
concentrations above DEQ IHSB Residential PSRGs, DWM Risk Calculator risk thresholds for
residential use, or typical metals concentrations which are consistent with background 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
WRITING PRIOR TO COMPLETING TRANSPORT ACTIVITIES. Please refer to Brownfields IR 15 for

18
EMP Version 2, January 2021
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 the cut-fill plan, soil is not expected to be exported from the Site. Based upon the large
size of the Site, even if there is excess soil, it is anticipated that it can be placed somewhere on-
Site. However, if soil needs to be exported, a sampling plan will be developed and submitted to
DEQ Brownfields for review and approval once the volume of soil for export is known. Generally,
soil samples will be collected from export soil at a rate of 1 composite sample consisting of 3 to 5
soil sample aliquots for every approximately 1,000 cubic yards of export.

DEQ approval of the sampling plan 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 Subtitle D lined facility, DEQ
Brownfields and DEQ Soil Waste Section 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
details related to the proposed plans).

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:
Chlorinated solvent impacts are present in groundwater at the Site. Note that the developer
plans to proactively install a passive vapor intrusion mitigation system (VIMS) during
construction of the industrial warehouse. As part of the VIMS design, the locations of sub-grade
utilities will be evaluated to confirm that the proposed VIMS will effectively minimize potential
vapor intrusion from soil vapor associated with groundwater impacts potentially migrating
preferentially through sub-grade conduits

☐ 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, pellets, 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 by the contractor or an environmental professional to protect workers during utility
installation activities. Safety screening activities include monitoring the worker breathing zone with a
calibrated photoionization detector and/or other appropriate instrument when personnel are 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

20
EMP Version 2, January 2021
PART 2. GROUNDWATER
1) What is the depth to groundwater at the Brownfields Property?
The depth to groundwater in the southern portion of the property (MW-5 and MW-7) is
approximately 11 to 13 ft bgs, 9 to 13 feet in the eastern portion of the Site (MW-9), and
approximately 4 to 5 ft bgs in the northern portion of the Site (AMW-106 and AMW-410) (See
Figure 6 for monitoring well locations).
2) Is groundwater known to be contaminated by ☒onsite ☐offsite ☐both or ☐unknown
sources? Describe source(s):
Groundwater sampling has been performed at the site beginning in the early 1990s as part of
previous investigations. The source of the groundwater contamination is identified as historical
activities at the Site. Former remediation efforts included the operation of a pump and treat
groundwater recovery system and a network of air sparge wells. On-Site groundwater is
impacted by VOCs and metals at concentrations exceeding the North Carolina Administrative
Code (NCAC) 02L.0202 Groundwater Quality Standard (2L Standard) and/or the June 2021 DEQ
Division of Waste Management (DWM) Non-Residential Groundwater Screening Levels (GWSL).
VOCs detected above 2L Standards in on-Site groundwater include carbon tetrachloride,
chloroform, 1,1-dichloroethane, 1,2-dichloroethane, 1,1-dichloroethene, cis-1,2-dichloroethene,
methylene chloride, 1,1,1,2-tetrachloroethane, tetrachloroethene (PCE), 1,1,1-trichloroethane,
1,1,2-trichloroethane, and trichloroethene (TCE). Metals detected above 2L Standards in on-Site
groundwater include chromium, manganese, and vanadium. VOCs detected above the Non-
Residential GWSLs include carbon tetrachloride, chloroform, 1,1-dichloroethene, PCE, 1,1,2-
trichloroethane, and TCE. The most recent groundwater analytical data for each well and
sampling locations are provided in Table 2 and Figure 6, respectively.

3) What is the direction of groundwater flow at the Brownfields Property?
Groundwater flow is generally to the east towards an unnamed stream (Figure 3) located east of
the railroad tracks.

4) Will groundwater likely be encountered during planned redevelopment activities?
☒Yes ☐No
If yes, describe these activities:
The proposed redevelopment plans include stormwater management ponds on the
northwestern and southwestern portions of the Site. Based on the measured high seasonal
groundwater table, impacted groundwater may be encountered during installation of the
northwestern pond. The PD plans to install a sealed liner in the pond to provide a barrier
between the groundwater table and the stormwater pond and prevent groundwater infiltration. 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).
Based on previous assessment activities, contractors will be made aware of areas at the Site
where groundwater is impacted and an environmental professional will be contacted to
conduct safety screening if groundwater is encountered in these predetermined areas. Should

21
EMP Version 2, January 2021
groundwater be encountered outside of areas of known impacts, the contractors will contact an
environmental professional 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.

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:

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
DEQ Brownfields previously approved the abandonment of all of the monitoring and remediation
wells located to the west of the railroad in preparation for the Site redevelopment activities, and the
wells were abandoned in 2018.

22
EMP Version 2, January 2021
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):
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 concerns (i.e., chemicals, tanks, drums, pellets, 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.

PART 4. SEDIMENT

1) Are sediment sources present on the property? ☒ Yes ☐ No

2) If yes, is sediment at the property known to be contaminated: ☒ Yes ☐ No ☐ Unknown

3) Will workers or the public be in contact with sediment during planned redevelopment
activities? ☐ Yes ☒ No

4) Attach a map showing location of known contaminated sediment at the property.

5) In the event that contaminated sediment is encountered during redevelopment activities, list
activities for management of such events (stream bed disturbance):
A total of 11 sediment samples have historically been collected at the Site, three of which [SED-1
(1992), SED-2 (1992), and SED-5 (1997)] contained concentrations of total chromium above the
Industrial/Commercial PSRGs and background levels. These sediment samples are not associated
with a surface water body or stream, but rather a former drain line effluent run-off area and
associated former drainage swale. These locations are within a fill area of the grading plan, and as
such, no disturbance of the sediment in this area is anticipated. Sediment analytical data and
sampling locations are provided in Table 1 and Figure 5, respectively.

IHSB Industrial/Commercial Screening Levels:
Soil Vapor:………..☒ Yes ☐ No ☐ Unknown
Groundwater:…..☒ Yes ☐ No ☐ Unknown
2) Attach a map showing the locations of soil vapor contaminants that exceed site
screening levels.
3) If applicable, at what depth(s) is soil vapor known to be contaminated?

4) Will workers encounter contaminated soil vapor during planned redevelopment activities?
☐ 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 during utility installation
activities in Limits of Groundwater Contamination that may impact soil vapor at unacceptable
levels. Safety screening activities include monitoring the worker breathing zone with a calibrated
photoionization detector or other appropriate instrument. 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.

In October 2011, Hart & Hickman, PC performed a soil gas investigation at the Site within the Limits
of Groundwater Contamination area, as depicted on the Brownfields Plat, and within and around the
footprint of the proposed building. Seven soil gas samples were collected at approximately 6 ft bgs.
Several VOCs (carbon tetrachloride, chlorobenzene, chloroform, 1,2-dichlorobenzene, 1,2-
dichloroethane, 1,1-dichloroethene, ethylbenzene, hexachlorobutadiene, 1,1,2,2-trichloroethane,
tetrachloroethene, 1,1,1-trichloroethane, 1,1,2-trichloroethane, trichloroethene, and m,p-Xylene)
were detected in at least one sample at concentrations exceeding the DEQ IHSB Non-Residential Soil
Gas Screening Levels (SGSLs).

In December 2015, Terracon collected four soil gas samples west of the Limits of Groundwater
Contamination at the Site and within the footprint of the proposed building from depths of 3 to 5 ft
bgs. VOCs were not detected above Non-Residential SGSLs. Soil gas analytical data and sampling
locations are provided in Table 3 and Figure 7, respectively.

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
In the unlikely event there is evidence of potential indoor air issues (i.e., unusual odors) during
development activities, the area will be evacuated and appropriate safety screening of the indoor air
will be performed. If warranted, safety screening procedures will be conducted by an environmental
professional and will include periodically screening with a calibrated photoionization detector or other
appropriate device to identify potential indoor air issues. If results indicate further action is
warranted, appropriate engineering controls (such as use of industrial fans) will be implemented.

26
EMP Version 2, January 2021
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
☒ Metals RCRA List (8) (arsenic, barium, cadmium, chromium, mercury, lead, selenium and

☒ Other Constituents & Analytical Method(s) (i.e. Hexavalent Chromium, Herbicides, etc.)
Please note, if field observations indicate the need for additional analyses, they should
be conducted, even if not listed here.
Hexavalent Chromium 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
concerns (i.e., tanks, drums, or waste materials) that, if encountered, will need proper
management. Prior to beginning Site work, Hart & Hickman 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 redevelopment activities, the
environmental actions noted below will be used to assist in appropriate management of the sub-
surface environmental concern and potentially impacted Site media.

Underground Storage Tanks:
In the event that an unknown UST or impacts associated with a UST release are discovered at the
Site during redevelopment activities, the UST and/or UST related impacts will be addressed through
the Brownfields Program. DEQ Brownfields will be notified within 48-hours of discovery of the UST.

If an unknown UST is encountered, the UST will be removed, if possible, and transported off-Site for
disposal at a suitable facility. Prior to removing the UST from the ground, residual fluids, if any, will
be sampled for VOCs, SVOCs, and RCRA metals as needed for disposal purposes, unless it is obvious
that the residual fluid is a petroleum fuel. If a UST is encountered that cannot be removed, it may

27
EMP Version 2, January 2021
be abandoned in-place with prior DEQ approval and construction will proceed. Where appropriate,
the bottom of the UST may be penetrated after fluid removal and 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 in this EMP.

Sub-Grade Feature/Pit:
If a sub-grade feature or pit is encountered, it will be removed from the Site, if possible and
construction will proceed. Where appropriate, the bottom may be penetrated after removal of
solids (if any) 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 Hart & Hickman. Hart & Hickman will observe the suspect
materials and collect samples for laboratory analysis, if warranted. 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 (or other analyses as appropriate based on the type of waste
material). Information will be provided to DEQ Brownfields regarding the permitted facility used for
disposal of the waste or significantly impacted soil. Areas of suspected contaminated soil that
remain at the Site after excavation is complete above the DEQ IHSB Residential PSRGs will be
managed pursuant to this plan

EMP Version 2, January 2021

POST-REDEVELOPMENT REPORTING

☒ Check this box to acknowledge that a Redevelopment Summary Report will be required for the
project. If the project duration is longer than one year, an annual update is required and will be
due by January 31 of each year, or 30 days after each one-year anniversary of the effective date of
this EMP (as agreed upon with the Project Manager). These reports will be required for as long as
physical redevelopment of the Brownfields Property continues, except that the final
Redevelopment Summary Report will be submitted within 90 days after completion of
redevelopment. Based on the estimated construction schedule, the first Redevelopment Summary
Report is anticipated to be submitted on 1/31/2022

The Redevelopment Summary Report shall include environment-related activities since the last
report, with a summary and drawings, that describes:
1. actions taken on the Brownfields Property;
2. soil grading and cut and fill actions;
3. methodology(ies) employed for field screening, sampling and laboratory analysis of
environmental media;
4. stockpiling, containerizing, decontaminating, treating, handling, laboratory analysis and
ultimate disposition of any soil, groundwater or other materials suspected or confirmed
to be contaminated with regulated substances; and
5. removal of any contaminated soil, water or other contaminated materials (for example,
concrete, demolition debris) from the Brownfields Property (copies of all legally required
manifests shall be included).

☒ Check box to acknowledge consent to provide a NC licensed P.G. or P.E. sealed, Redevelopment
Summary Report in compliance with the site’s Brownfields Agreement.
