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

2) For the Area of Proposed Redevelopment on the Brownfields Property, attach tabulated data
summaries for each impacted media and figure(s) with sample locations.
PART 1. Soil
1) Known or suspected contaminants in soil (list general groups of contaminants):
Petroleum and chlorinated solvents as documented in previous assessment reports
7
EMP Version 2, January 2021

2) Depth of known or suspected contaminants (feet):
Based on available data, if utility installations encounter contaminated soil, it will likely be
limited in area and volume. The water table is estimated to be greater than 15 feet below land
surface (BLS) for the proposed utility construction areas which is greater that the estimated
maximum depth of utility excavation activities. As such, site utility work us unlikely to encounter
groundwater and the well -documented location of a groundwater plume. Contingencies for
encountering contaminated media are included.
3) Area of soil disturbed by redevelopment (square feet):
The estimated total linear feet for the main water and sewer lines is approximately 13,100 linear
feet. Assuming the approximately average 30 ft width of soil disturbance per linear foot of line,
this provides a total approximately 393,000 square feet of soil disturbance for construction of
the main lines. Other utilities will be installed at different times and the estimated area of
disturbance cannot be estimated at this time. Equipment laydown areas will be located on
existing concrete building slabs and paved areas.
4) Depths of soil to be excavated (feet):
Maximum 15 feet BLS
5) Estimated volume of soil (cubic yards) to be excavated (attach grading plan):
Using an estimated average depth of 8 ft and width of 6ft (to include trench sloping) and an
estimated total of 13,100 linear ft, this provides and estimated volume of approximately 23,300
cubic feet of soil that will be disturbed during construction of the main water and sewer lines.
6) Estimated volume of excavated soil (cubic yards) anticipated to be impacted by contaminants:
The volume of soil impacted by contaminants cannot be reasonably estimated at this time but is
likely to be limited to localized areas. As described in this EMP, measures will be included in the
event that field observations indicate the potential presence of impacted soil during Site work.
7) Estimated volume of contaminated soil expected to be disposed of offsite, if applicable:
N/A
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 preliminarydata available).

Additional comments:
Based on available data, if utility installations encounter contaminated soil, it will likely be
limited in area and volume. As described in the following section, field screening will be used
to evaluate if soils appear to be non -impacted and can be reused as backfill for utility
excavations and grading within the area disturbed by utility work.
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

field screening:
Click or tap here to enter te,._
During construction, an EP will be present for initial excavation activities to make field
observations and field screen soils using PID headspace and ambient air methods to
10
EMP Version 2, January 2021

evaluate for evidence of impacts, particularly during management of soils in the deepest
excavation areas and closest to known/potential contaminant sources associated with
previous industrial use of the site. The level of on -site EP oversight may decrease if initial
screening results consistently suggest a lack of impacts.
Based on previously discussed existing assessment data, it is unlikely that an EP will be
required on -site for all earthwork activities. Based on initial observations during
construction, the EP will work with the PD and construction personnel (Contractor) to
determine the scope and frequency for subsequent oversight to reasonably document that
remaining soils are managed in accordance with this EMP. This may include moving to
standby and allowing the site Contractor or contractor designated representative to
provide primary oversight of construction activities. The Contractor of designated
representative will notify the EP if field conditions are encountered that could indicate the
potential presence of impacted soil (i.e. staining). While on standby, the Contractor of
designated representative will fill out a weekly log approved by the EP and provide photo
log (as necessary) to document Brownfields Property conditions. The weekly reports will be
included in a final EMP Implementation Report at the end of the project. While on standby,
the EP will initially make weekly site visits, at a minimum, to document Brownfields
Property conditions reported by the Contractor. The need and frequency of standby EP
visits will be adjusted as needed based on site conditions encountered during site
construction.
❑ 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.):
Based on previously described assessment results, no additional sample collection is
currently planned unless the following conditions are encountered:
Field Evidence of Potential Soil Impacts: If field evidence indicate the potential presence
of soil impacts that are not consistent with previous assessment findings, the soil will
either be 1) transported to a NCDEQ permitted facility for disposal; or 2) sampled and
evaluated as potential on -site fill, beneficial fill at a non-Brownfields property or fill at
another Brownfields property. Under these conditions, the soil may need to be sampled
in -situ or segregated to allow for additional sample collection. Segregation methods
utilized by the Contractor may include temporary stockpiling or roll -off boxes. Stockpiling
and/or in -situ sampling will be conducted in general accordance with NCDEQ guidance
using the analytical laboratory methods included in this EMP for import sampling.
Sampling will be conducted by the Contractor as needed based on disposal facility permit
11
EMP Version 2, January 2021

requirements or to explore potential reuse options for other sites as described below.
Additional Data to Support Soil Export to Another Site: Based on current site grading
plans, this scenario is considered unlikely. However, if excess soil is generated during site
grading, additional soil sampling may potentially be needed to support export of soil to a
non-Brownfields property as beneficial fill and/or fill on another Brownfields property.
Sampling would only be conducted if additional data is needed to evaluate if Brownfields
Property soil increases risk at the receiving property. Primary reliance on existing Phase II
Assessment data will be used be used to satisfy this requirement. If necessary, stockpile
and/or in -situ sampling will be conducted in accordance with NCDEQ guidance using the
analytical laboratory methods included in this EMP for import sampling to support this
effort. Additional NCBP correspondence and approval may be required to establish data
needs. The sampling strategy and level of effort for sampling both export soils and
background soil conditions on receiving sites (as needed) will likely depend on the
characteristics of the receiving site.

Part I.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.
Exported soil will likely be limited to less than 2,000 cubic yards of soil excavated with evidence
of impacts as identified by the EP. At this time, if impacted soil is encountered, the soil will be
exported to a NCDEQ permitted facility for disposal purposes. No off -site export to another
construction site (i.e. sites that are not a permitted disposal facility) is anticipated for this utility
construction phase of this project.
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 thata 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

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:
Trench dams will be constructed for the main line water, sewer, electrical, natural gas and
communication line excavations that are backfilled with a stone aggregate to mitigate the
potential risk of lateral vapor migration outside the of the area of the documented
groundwater plume. Typical trench dam details are provided in Attachment A. Trench dams will
for every main utility line excavation located approximately 100 ft outside the mapped edge of
the groundwater plume for portions of the utility excavations that intersect the groundwater
plume. Figure 3 provides the approximate location of the proposed trench dams. Trench dams
will also be installed for utility stub excavations to individual buildings. Attachment A also
provides details for sealing of internal utility void spaces (i.e. electrical conduit). Results of soil
gas testing (as presented in a 27 May 2021 Soil Gas Work Plan), will be used to further evaluate
the need and placement of the trench dams. Geosyntec will provide an update to the NCBP to
confirm the final trench dam and utility sealing strategy prior to construction.

Other comments regarding managing impacted soil in utility trenches:
Potentially impacted soils will not be placed back into trenched if they represent a potential vapor
risk.
PART 2. GROUNDWATER
1) What is the depth to groundwater at the Brownfields Property?
Available data reports that the approximate groundwater depth is between 1 to 18 feet bgs.
However, underlying Triassic geological conditions may be creating confined groundwater
16
EMP Version 2, January 2021

conditions, and as such, the actual depth of groundwater is likely to be at greater depths. Based
on this information, excavations are anticipated not to encounter the water table. Field
observations during construction will be used to confirm this assumption.
2) Is groundwater known to be contaminated by ®onsite ❑offsite ❑both or ❑unknown
sources? Describe source(s):
Yes — as documented in assessment reports maintained by the NCBP
3) What is the direction of groundwater flow at the Brownfields Property?
On the western portion of the property, estimated groundwater flow will follow topography
moving west-southwest. On the eastern portion of the property, estimated groundwater flow
will follow topography moving east -south east.
4) Will groundwater likely be encountered during planned redevelopment activities?
❑Yes ®No
If yes, describe these activities:
Click or tap here to enter tex
Regardless of the answer; in the event that contaminated groundwater is encountered
during redevelopment activities (evenif no is checked above), list activities for contingent
management of groundwater (e.g., dewateringof groundwater from excavations or
foundations, containerizing, offsite disposal, discharge to sanitary sewer, NPDES permit, or
sampling procedures).
In the event that groundwater is encountered, it will be displaced in the excavation and/or
pumped into a tanker truck, frac tank or other container approved by the EP. Sampling and
analysis will be conducted by the EP as needed to characterize the water for disposal purposes
based on the requirements of the disposal facility. The on -site wastewater treatment plant
(WWTP) may be used to treat containerized groundwater pending analytical results and
regulatory approval.
5) Are monitoring wells currently present on the Brownfields Property?.................OYes ❑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
17
EMP Version 2, January 2021

disturbance until notification to DEQ Brownfields can be made and approval for
abandonment is given.
7) Please provide additional details as needed:
Monitoring wells will be protected and abandoned on an as -needed basis.
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 resaonsible for replacement of the well.
PART 3. SURFACE WATER
1) Is surface water present at the property? ® Yes ❑ No ❑ Unknown
2) Attach a map showing the location of surface water at the Brownfields Property.
3) Is surface water at the property known to be contaminated? ® Yes ❑ No
4) Will workers or the public be in contact with surface water during planned redevelopment
activities? ❑ Yes ® No
5) In the event that contaminated surface water is encountered during redevelopment
activities, or clean surface water enters open excavations, list activities for management of
such events (e.g. flooding, contaminated surface water run-off, stormwater impacts):
Available information indicates impacted surface water is not present at the site with the
exception of the lagoons within the wastewater treatment plant area. At this time, utility
construction will not impact wastewater treatment plant lagoon areas. As such, impacted surface
water scenarios would only occur during a rainfall event during excavation activities. If areas of
impacted soil are encountered during construction, as needed, they will be covered with plastic
by the Contractor to prevent direct contact with rain/surface water while soil grading activities
are occurring. Stockpiles will be managed per Figure 1 of this EMP. If applicable, water that has
contacted impacted soil will be contained on -site using diking, trenching and/or will be allowed
to infiltrate into soils or placed into a tanker truck, frac tank or other storage container by the
Contractor as approved by the EP. Pending regulatory approval, the waste water lagoons may
also potentially be utilized to manage storm water from construction areas. If needed, water will
be sampled by the EP for laboratory analysis to evaluate handling/disposal options. Sampling
and analysis will be conducted based on the requirements of the disposal facility. As needed, the
impacted area will be covered by at least two feet of clean soils.
PART 4. SEDIMENT I

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, orother 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
® Metals RCRA List (8) (arsenic, barium, cadmium, chromium, mercury, lead, selenium and
silver)

Please provide details on the proposed methods of managing the following commonly
encountered issues during redevelopment of Brownfields Properties.
Available data indicates a low potential to encounter conditions beyond those already identified
under previous assessment reports.
Underground Storage Tanks:
Click or tap here to enter text Available information indicates that it is unlikely for USTs to be
present at the site. In the unlikely event that a UST is identified, UST closure and corrective action
will be followed per applicable NCDEQ UST Section regulations and guidance. This may include the
use of a mobile laboratory with Ultra -Violet Fluorescent (UVF) capabilities to help determine the
extent of impacts in the field. Confirmatory soil samples will be collected from four sidewalls and at
least one base sample (depending on size) of the final excavation. Confirmation analysis will include
VOCs by EPA Method 8260, SVOCs by EPA Method 8270, RCRA Metals by EPA Methods 6020 and
7471, and Hexavalent Chromium by EPA Method 7199, as applicable, to meet NCBP requirements.
Additional analysis may include those listed in UST Section Guidance, Table 3. Approved Methods
for Soil Analyses at Petroleum UST Closures and Over -Excavation and at Site Checks
(https://files.nc.gov/ncdeq/Waste%20Management/DWM/UST/Corrective/2OAction/ACA/`20table
s%20Chng3%20112013.pdf).
Sub -Grade Feature/Pit:
Click or tap here to enter text Because of the historical use of the Brownfields Property, it is unlikely
for sub -grade features/pits to be encountered beyond what has already been identified under
previous assessment reports. In the event that such features are identified, they will be handled
under Guidelines for Assessment and Cleanup of Contaminated Sites (NCDEQ IHSB, January 2020)
(https://files.nc.gov/ncdeq/Waste%20Management/DWM/SF/IHS/guidance/IHSB RemediationGuid
ance012720.pdf)
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:
The NCBP will be notified in the event that buried wastes are encountered. Work will be stopped
22
EMP Version 2, January 2021

and plans will be conducted to evaluate the waste if the EP believes that the characteristics of the
material is inconsistent with data from previous assessment reports.
Re -Use of Impacted Soils On -Site:
Grossly impacted soils will not be re -used on -Site. Per the procedures identified in this EMP, the EP
will screen soils to evaluate the presence of impacts, if any, and appropriate re -use scenarios.
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:
