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

EMP Version 2, January 2021

PART 1. Soil
1) Known or suspected contaminants in soil (list general groups of contaminants):

Numerous subsurface investigations have been conducted at the site since 2000 to investigate
impacts related to a release (NCDEQ Incident No. 15378) from an underground storage tank (UST)
system formerly located on the adjacent property to the northwest of the site (521 East Morehead
Street). These investigations identified low levels of petroleum constituents at depth, near the
water table. Naphthalene was identified above its protection of groundwater Preliminary Soil
Remediation Goal (PSRG) in two locations (P-1, 12 to 16 feet below land surface [bls]; and P-9, 12
to 16 feet bls), above its residential PSRG in one location (P-2, 12 to 16 feet bls), and above its non-
residential PSRG at one location along the property line with 521 E. Morehead Street (GP-9, 11 to
13 feet bls). The following constituents were also identified above their protection of groundwater
PSRG at GP-9: ethylbenzene, xylenes, isopropylbenzene, n-propylbenzene, 1,3,5-
trimethylbenzene, n-butylbenzene, and sec-butylbenzene. 1,2,4-trimethylbenzene was identified
above its residential PSRG at GP-9 as well. Other petroleum constituents or volatile organic
compounds (VOCs) were not identified above their PSRGs at the site during historical sampling
events.

In 2020, Terracon collected additional soil samples at the site for VOCs, semi-volatile organic
compounds (SVOCs), and Resource Conservation and Recovery Act (RCRA) Metals (plus hexavalent
chromium). The sole compound identified above laboratory detection limits in the samples
collected was arsenic at concentrations ranging from 0.72 milligrams per kilogram (mg/kg) to 2.6
mg/kg. While these concentrations exceed arsenic’s residential PSRG, these concentrations are
considered naturally occurring based on the magnitude, range, and frequency of detections, as
well as the lack of a historical process at the site that could have resulted in arsenic releases.

2) Depth of known or suspected contaminants (feet):
Contaminants at concentrations exceeding their non-residential PSRG(s) have been detected in a
sample collected from 11 to 13 feet bls. Contaminants exceeding their residential or protection
of groundwater PSRG(s) from samples collected from between 11 and 16 feet bls.

3) Area of soil disturbed by redevelopment (square feet):
Approximately 123,275 square feet.

4) Depths of soil to be excavated (feet):
Based on the existing grading plan, soil excavation beneath the southwestern portion of the
Enclave Building will be up to approximately 7 feet. Cut beneath the Overlook Building will be
limited to the approximate top 2 feet of soil. The areas of cut and fill are provided as a heat map
in Exhibit 4.

5) Estimated volume of soil (cubic yards) to be excavated (attach grading plan):

01671-003/00322972
10
EMP Version 2, January 2021
Per the current grading plans, approximately 10,642 cubic yards of soil will be cut at the site.

6) Estimated volume of excavated soil (cubic yards) anticipated to be impacted by contaminants:
Sample data does not exist for the majority of the soils to be excavated at the site, as most of the
historical samples were collected from deeper than the proposed cut depths (S-4, 0 to 5 feet bls is
the main sample within the cut area that may be representative of soils to be excavated). The
areas of cut are not expected to be impacted based on the site history; however, Terracon will be
submitting a Work Plan under separate cover for the sampling of soils in areas of cut to properly
characterize these soils prior to their disposal (see Part 1.B below).
7) Estimated volume of contaminated soil expected to be disposed of offsite, if applicable:
Based on current grading plans, there will be a net cut of approximate 4,614 cubic yards that will
require off-site disposal. It is not anticipated that the proposed cut soils at the site are
contaminated; however, as discussed in Part 1.C below, Terracon will submit a Work Plan to
sample and characterize soils that must leave the site for disposal purposes.

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).

sampling the soils will be implemented as described in the section for “Contingency for
encountering unknown tanks, drums, or other waste materials.” Laboratory analysis for
such soil sampling will be determined based on the nature of the unexpected impacts and
a discussion with the Brownfields Project Manager.

If soil samples are collected for analysis, please check the applicable chemical analytes:
☒ Volatile organic compounds (VOCs) by EPA Method 8260
☒ Semi‐volatile organic compounds (SVOCs) by EPA Method 8270

Click or tap here to enter text.

☒ Other Constituents & Respective Analytical Method(s) (i.e. Hexavalent Chromium,
Herbicides, etc.): Specify Analytical Method Number(s):
Hexavalent chromium by EPA Method 7199.

Laboratory analysis for soil sampling will be determined based on the nature of the
unexpected impacts and a discussion with the Brownfields Project Manager at the time
the impacts are encountered.
☒ Check to confirm that stockpiling of known or suspected impacted soils will be conducted
in accordance with Figure 1 of this EMP. Stockpile methodology should provide erosion
control, prohibiting contact between surface water/precipitation and contaminated soil,
and preventing contaminated runoff. Explain any variances or provide additional details as
needed:

☒ Final grade sampling of exposed native soil (i.e., soil that will not be under buildings or
permanent hardscape). Select chemical analyses for final grade samples with check boxes
below (Check all that apply):
☒ Volatile organic compounds (VOCs) by EPA Method 8260
☒ Semi‐volatile organic compounds (SVOCs) by EPA Method 8270
Deviations from Figure 1 will not occur during stockpiling of soils. If construction logistics (e.g. schedule,
physical site constraints, etc.) prevent proper stockpiling of soils, the contingency procedures will be to
directly load soils onto trucks for export and disposal off the site. Should this alternative be required,
the exported soils will be sampled in accordance with Brownfields requirements and the selected
disposal facility will be contacted to discuss sampling requirements (analyses, frequency). Brownfields
approval will be obtained prior to soil export from the 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.

Based on preliminary development plans for the site, it is expected that exposed soils (not
capped under structures or hardscapes) will be limited to relatively minor landscaped
areas at the site between the buildings and sidewalks.

Six composite soil samples will be collected from these areas of exposed soil, as shown on
Exhibit 7. Composite soil samples will be collected using a decontaminated hand auger
from shallow depths (0 to 2 feet) in accordance with the sampling procedures outlined in
the NCDEQ Inactive Hazardous Site Branch’s (IHSB) Guidelines for Assessment and Cleanup
of Contaminated Sites (January 2020). Each of the samples will be composited from three
or four individual locations. The soils from each location will be divided equally with one
half placed in a sealed plastic bag that is placed on ice within a cooler and the other half
placed in a sealed plastic bag that is left in the sun and allowed to volatilize for
approximately 5 to 10 minutes. After the volatilization period, the headspace of the second
plastic bag will be screened for volatile vapors using a photo-ionization detector (PID). A
grab sample for VOC analysis will be collected from the sealed plastic bag that had been
stored on ice from the location exhibiting the highest PID reading. For composite sample
collection, soils from the sealed plastic bags (placed on ice) from each set of borings will
then be composited using a decontaminated stainless-steel bowl and spoon via the sample
homogenization procedures outlined in the U.S. Environmental Protection Agency’s
SESDPROC-300-R3 (June 11, 2020) guidance.

Samples will be analyzed for VOCs (8260), SVOCs (8270), RCRA 8 Metals (6010/7471), and
hexavalent chromium (7199). In addition to the six composite samples, Terracon will also
collect the following samples for quality assurance/quality control purposes: one

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.”

Requirements for importing fill:

1) Will fill soil be imported to the site?................................................ ☐ Yes ☒ No ☐ Unknown

Based on current grading plans, the site has a net cut of approximately 4,614 cubic yards. The
proposed redevelopment will utilize cut soils from portions of the site to satisfy fill
requirements in other areas. As such, no fill soil is planned for import at this time.

2) If yes, what is the estimated volume of fill soil to be imported?
0 cubic yards.

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.)
Some portions of the site will require fill up to approximately 8-feet (filling and raising grade of the
existing stormwater detention pond in the northeast portion of the site). The majority of areas to
receive fill will only require between 0 and 2 feet of fill. As discussed above, import of soils for use
of fill is not planned, as cut soils from other portions of the site will be utilized as fill material.

EMP Version 2, January 2021
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:

There are no plans for import fill. If soils are proposed for import to the site in the future; a work
plan for pre-import sampling would be submitted to the Brownfields PM for approval, or such soils
will be obtained from a source which has been pre-approved by the Brownfields Program as a
suitable fill source and pre-import sampling is not necessary.

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.

Not applicable, as import soil is not currently planned. If plans change and soils are to be imported,
attempts will be made to import them from an NCDEQ-approved source. If construction
plans/logistics dictate an alternative, non-approved fill source be selected during the project, a
work plan for pre-import sampling will be submitted to the Brownfields PM for approval that
demonstrates acceptable criteria for obtaining soils from the alternate fill source. Approval will be
obtained from the PM prior to the import of soils.

6) Please check the applicable chemical analytes for fill soil samples. (Check all that apply):
☒ Volatile organic compounds (VOCs) by EPA Method 8260
☒ Semi‐volatile organic compounds (SVOCs) by EPA Method 8270
☒ Metals RCRA List (8) (arsenic, barium, cadmium, chromium, mercury, lead,
selenium and silver): Specify Analytical Method Number(s):

☒ 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.

A work plan will be prepared and submitted under separate cover if it is determined that the
source of any import soils has not been pre-approved by the NCDEQ.

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 current grading plans, approximately 4,614 cubic yards of excavated soils will require
export from the site. Existing sample data does not exist for these soils. Terracon is preparing a
Work Plan to be submitted under separate cover to adequately characterize these soils for disposal
purposes. Disposal decisions for these soils will be based on the analytical results of said sampling.
Based on site history and past sampling, it is not anticipated that the soils to be exported will be
impacted by contaminants. Soils determined to not be impacted would be disposed at a nearby
LCID landfill such as the Lakeview Road Landfill, Reeves Landfill, Old 27 Landfill, or Kelly Road
Landfill (please note that these landfills are provided as examples of possible LCID disposal facilities
and this list is not intended to limit the PD’s disposal options). Soils determined to be impacted by
contaminants would either be disposed off-site at a permitted, lined landfill (Subtitle D) such as
the CMS Republic Landfill located at 5105 Morehead Road in Concord, North Carolina) or instead
transferred to another Brownfields site with similar contaminants and contaminant
concentrations, should such a site be present nearby and willing to accept the soils and prior DEQ
approval is obtained.

Additional off-site soil disposal methods (landfarming, as beneficial fill at a non-Brownfields
property) have also been selected to provide flexibility in the event the PD wishes to change its
contingency plans.

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 requirements 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

01671-003/00322972

EMP Version 2, January 2021
the potential for risk to human health and the environment at the receiving Brownfields
property, and that a record of the acceptance of such soils from the property owner of
the receiving site is provided to the Brownfields Program. 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).
See Part 1.C Item 1 above. Following completion of in situ soil characterization, proposed soil
export disposal locations (other than CMS Republic) will be provided to the Brownfields
Program for approval before any export occurs.

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.

During initial site grading activities, workers should use appropriate safety personal protective
equipment (PPE). The on-site Health and Safety Plan will address potential exposure of workers to
constituents of concern (COCs). Soils will at times be disturbed for the construction of utilities or
other structures. With respect to subsurface utility construction at the site, the general rule will be
to remove and stockpiled soils so that a “last out, first in” process occurs. During excavation, soils in
the upper 2 feet will be stockpiled and segregated as the first materials removed. These soils/fill
materials will be the last returned to the excavation during backfilling. Soils will typically “bulk” or
expand in volume when disturbed by excavation. The contractor will compact these materials into
place according to the compaction requirements of the construction design. If no specifications for
compacted fill exist, the contractor will tamp the materials in place using the mechanical excavator
or equivalent. Utilities or structures will replace a certain volume of soils in these areas, resulting in
excess soils as excavation spoils. After the initial grading of the site, the worker and contractor
should plan from onset of construction to maintain a cap comprised of either (a) clean fill, or (b)
other barrier approved by the NCDEQ for areas that will not be capped with a building, asphalt, or
concrete surface. If excess contaminant impacted soils/fill are produced from excavation as spoils
which cannot be restored to original depths through the process of “first out, last in”, they must be
handled with special care. The worker or contractor will work with the Brownfields Project Manager
to ensure that, if the soils are contaminated, they are either properly re-used on the site or disposed
at an off-site location.

EMP Version 2, January 2021
☒ 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:
Click or tap here to enter text.

☒ If no, include rationale here:
Soil vapor data at the site indicates that vapor mitigation measures are not necessary at the site.
Summaries of the NCDEQ Risk Calculator model results, which do not indicate unacceptable risk
associated with vapor intrusion from soil vapor concentrations obtained in both 2020 and 2021,
are included as attachments to the EMP.

☐ Unknown, details to be provided in the Vapor Mitigation Plan for the site.

Click or tap here to enter text.

Other comments regarding managing impacted soil in utility trenches:
Concerns and methods for handling impacted soils do not preclude or modify any of the
Occupational Safety and Health Administration (OSHA) requirements for worker safety
incumbent upon contractors for regular site safety and trenching/excavation activities. OSHA
requirements will dictate adjustments of the soil management methods, where necessary.

PART 2. GROUNDWATER

1) What is the depth to groundwater at the Brownfields Property?
Depth to groundwater has been ranging from approximately 17 to 25 feet bls at the site.

2) Is groundwater known to be contaminated by ☐onsite ☒offsite ☐both or ☐unknown
sources? Describe source(s):
Existing data indicate various petroleum constituents, including benzene, toluene, ethylbenzene,
and xylene (BTEX) have been identified above their 2L Standards at the site. Refer to attached
Table 2 for specific concentrations.

These compounds are due to the release (NCDEQ LUST Incident 15378) from the UST system
formerly located on the adjacent property to the northwest of the site.

3) What is the direction of groundwater flow at the Brownfields Property?
Based on surficial topography, the direction of shallow groundwater flow is inferred to be toward
the east.

4) Will groundwater likely be encountered during planned redevelopment activities?
☒Yes ☐No
If yes, describe these activities:

01671-003/00322972
20
EMP Version 2, January 2021
Based on the proposed development plans, grading activities at the site are not anticipated to
exceed a depth of approximately 8 feet bls; as such, groundwater will likely not be encountered
during the majority of the soil work that will occur will not encountered groundwater. However,
the Overlook building will require the installation of deep foundations that will be installed into
bedrock, which averages approximately 31 feet bls. The installation of the foundations will be
achieved by drilling large diameter boreholes (ranging from approximately 3 to 6.5 feet) to the
necessary depth, installing concrete caissons within the boreholes, and then installing the deep
foundations inside the caissons. As these boreholes intersect the water table, it is anticipated
that some temporary dewatering will be necessary. The boreholes typically are open for
approximately one day prior to installation of the caissons. Based on the anticipated extent of
the interaction with groundwater during construction activities (e.g. during installation of
foundational caissons only), construction activities are not expected to modify existing
groundwater flow in a manner that would have an effect on adjacent properties or increase vapor
intrusion risk at the property.

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).

Generally speaking, excavations in areas where groundwater is encountered will be allowed
to re-infiltrate for approximately 24 hours, if it does not affect the construction schedule. If
the groundwater must be removed so that construction activities may proceed, the
groundwater will be discharged to a tanker or aboveground storage containers pending
approval by the Brownfields Program, and laboratory analysis for disposal. Copies of
laboratory data and disposal manifests will also be provided to the Brownfields Program.

In the case of the temporary dewatering that will likely be necessary during foundation
installation, the PD is currently evaluating its options. Such options may include off-site
disposal, temporary containerization coupled with on-site treatment (e.g. use of a granular
activated carbon filtration) prior to discharge in accordance with the site’s construction
stormwater permit, or discharge to the municipal POTW (if granted permission by the
municipality), etc. Please note that the above procedures are given as possible examples and
are not intended to limit the PD in its selection of the ultimate groundwater management
protocol(s). Once a groundwater management option that complies with all applicable laws
has been selected, the Brownfields Program will be contacted for approval.

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.

01671-003/00322972

EMP Version 2, January 2021
☐ 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
4) Will workers or the public be in contact with surface water during planned redevelopment
activities? ☐ Yes ☒ No
Stormwater can potentially accumulate in excavations and utility trenches during construction
activities following precipitation events. In the event stormwater management is required, the
applicable excavation activities should cease pending infiltration of the water or removal and
characterization of the water.
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):
Water is not anticipated to discharge into open excavations. Excavations and trenches shall be
graded, bermed, or provided with an equivalent barrier where necessary to help prevent surface
water and/or stormwater from entering excavations and/or leaving the site boundaries.
Stormwater or water from an unidentified source that collects in excavation areas will be allowed
to infiltrate naturally if construction schedule allows or removed so that construction activities
may proceed. The water will be containerized or diverted to an on-site stormwater management
basin where the water will be sampled for disposal characterization before it is allowed to leave
the site. Based on the types of contaminants documented on the site, water samples will be
analyzed for VOCs, SVOCs and RCRA metals. If containerized water is determined to be above
regulatory standards, the Brownfields Project Manager will be contacted, and the water will be
disposed in accordance with regulatory requirements.

Any identified monitoring wells will be abandoned in accordance with the applicable regulations,
following approval from NCDEQ.

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):
Not applicable. There are no known current or historical natural drainage features on the site.

PART 5. SOIL VAPOR

1) Do concentrations of volatile organic compounds at the Brownfields property exceed the
following vapor intrusion screening levels (current version) in the following media:
IHSB Residential Screening Levels:
Soil Vapor: ………..☒ Yes ☐ No ☐ Unknown
Groundwater: .….☒ Yes ☐ No ☐ Unknown
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?

In 2020, five soil vapor points were installed within the footprint of the planned building at depths
ranging from approximately 3 to 5.25 feet bls. While numerous VOCs were detected, the sole
compound exceeding its residential Soil Gas Screening Level (SGSL) was chloroform (at a concentration
of 8.37 µg/m3 vs. its residential SGSL of 8.1 µg/m3).

Five additional soil vapor points were installed and sampled at the site in 2021 to confirm the prior
results. The 2021 soil vapor points were installed to depths ranging from 5.25 feet to 8 feet bls. VOC
concentrations were not identified above their residential SGSLs.

Refer to the attached Tables 5 and 6 for specific soil vapor concentrations. Copies of modeled vapor
intrusion risk results using the NCDEQ Risk Calculator for both the 2020 and 2021 sample data sets are
also included behind the tables in the appendices. The NCDEQ Risk Calculator indicates there is not
unacceptable risk to future residential site occupants from the identified soil vapor VOC
concentrations.

01671-003/00322972
23
EMP Version 2, January 2021
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:
Volatile organic compounds (VOCs) have been identified in localized areas (building footprint)
within soil vapor and groundwater. The concentrations of VOCs detected within soil vapor were
below residential SGSLs with the exception of chloroform in one sample, at a level only slightly in
excess of its SGSL. Based on the identified levels, it is not anticipated that construction workers
will encounter contaminated soil vapor during redevelopment activities. However, during
construction, site workers will be informed of the possible presence of contaminated soil vapors
particularly in trenches and other excavations on the site. If during construction, workers identify
evidence of elevated vapor concentrations (odor, lightheadedness, etc.), work will be stopped
until Terracon can mobilize to the site to complete vapor screening activities. Work will not begin
again until the vapor field screening indicates concentrations have returned to background levels.

PART 6. SUB‐SLAB SOIL VAPOR
1) Do concentrations of volatile organic compounds at the Brownfields property exceed the
following vapor intrusion screening levels (current version) in sub-slab soil vapor:
IHSB Residential Screening Levels:
Soil Vapor:………..☐ Yes ☐ No ☒ Unknown
Groundwater:.….☐ Yes ☐ No ☒ Unknown
IHSB Industrial/Commercial Screening Levels:
Soil Vapor:………..☐ Yes ☐ No ☒ Unknown
2) Groundwater:…..☐ Yes ☐ No ☒ Unknown If data indicate that sub‐slab soil vapor
concentrations exceed screening levels, attach a map showing the location of these exceedances.
3) At what depth(s) is sub‐slab soil vapor known to be contaminated? ☐0‐6 inches ☐Other, please
describe:
There are no structures currently located on the site; as such, sub-slab soil vapor samples have not
been collected.

4) Will workers encounter contaminated sub‐slab soil vapor during planned redevelopment
activities? ☐ Yes ☐ No ☒ Unknown

☒ If no, include rationale here:
There are no structures currently located on the site.
5) In the event that contaminated soil vapor is encountered during redevelopment activities, list
activities for management of such contact
Volatile organic compounds (VOCs) have been identified in localized areas within soil vapor and
groundwater beneath the site. Vapors will be evaluated, as discussed in Part 5.

PART 7. INDOOR AIR

1) Are indoor air data available for the Brownfields Property? ☐ Yes ☒ No ☐ Unknown
2) Attach a map showing the location(s) where indoor air contaminants exceed site screening levels.
3) If the structures where indoor air has been documented to exceed risk‐based screening levels will
not be demolished as part of redevelopment activities, will workers encounter contaminated
indoor air during planned redevelopment activities? ☐ Yes ☒ No ☐ Unknown

☒ If no, include rationale here:
Not applicable.
4) In the event that contaminated indoor air is encountered during redevelopment activities, list
activities for management of such contact:

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

☒ If no or unknown, include rationale here as well as plans for pre-occupancy sampling, as
necessary:
Based on the 2020 and 2021 soil vapor sampling, concentrations of VOCs have not been
identified at levels that pose unacceptable risk to future residential occupants (see attached
NCDEQ Risk Calculator summaries).

DEQ’s determination is based on site conditions observed prior to redevelopment. While a
source of petroleum contamination is located on the property adjacent to the Brownfields
Property, based on the anticipated extent of the interaction with groundwater during
construction activities (e.g. during installation of foundational caissons only), construction
activities are not expected to modify existing groundwater flow in a manner that would have
an effect on adjacent properties or increase vapor intrusion risk at the property.

If yes, ☐ VIMS Plan Attached or ☐ VIMS Plan to be submitted separately
If submitted separately provide date:

VIMS Plan shall be signed and sealed by a NC Professional Engineer

If no, please provide a brief rationale as to why no vapor mitigation plan is warranted:
See above

Note that approval of this EMP does not imply approval with any vapor intrusion mitigation land
use restrictions or requirements of the recorded or draft Brownfields Agreement and that
separate approval of mitigation measures will be required.
Not applicable.

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 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.

Should potentially impacted materials be identified that are inconsistent with known site

Please provide details on the proposed methods of managing the following commonly
encountered issues during redevelopment of Brownfields Properties.
There is a possibility that materials of unknown type (tanks, drums or impacted soils) could be
present on the site. The worker and contractor will be able to recognize when conditions change at
the site. Field staff will be able to determine if a new discovery of changed chemical conditions has
occurred, and if so, if it is significant. If there is question of the significance of a new discovery or

01671-003/00322972
26
EMP Version 2, January 2021
changed condition, the environmental manager (Terracon) or equivalent qualified environmental
professional should make the determination. The worker or contractor will be alert during
earthwork for the following indications that will trigger the possible identification of a new condition
not addressed by previous investigations and evaluation. All work will be completed in accordance
with applicable regulatory requirements.

Prior to beginning site work, the environmental manager 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 the environmental manager
of the discovery of unknown subsurface features or potentially impacted media at the site.

Underground Storage Tanks:
Prior assessment reports have not identified suspected underground storage tanks (USTs) remaining
at the site. The worker and contractor will be cognizant of man-made containers or remnants of
containers of any material. The presence of whole or crushed drums or containers in excess of one
gallon in the soils in combination with odor or unique color changes may be indicative of a changed
condition. Should USTs, drums, or similar items be encountered during redevelopment activities, the
environmental manager (Will Frazier) will be contacted immediately, and the identified item should
remain as encountered. The NCBP Project Manager will be notified by the environmental manager
for the site within 48 hours of discovery. Following notification of the Brownfields Project Manager,
the UST or other containers will be removed from the ground after potential combustible vapors
have been stabilized. Residual fluids, if present, will be removed and sampled for VOCs, SVOCs, and
RCRA 8 metals. The fluids will be transported off-site for disposal at a suitable facility based on the
laboratory analytical results. The UST or other containers will be hauled to an off-site facility for
proper disposal and soil samples will be collected from the location of the UST or other containers
and analyzed for VOCs (EPA Method 8260B), SVOCs (EPA Method 8270D) and RCRA metals (EPA
Methods 6010D and 7471B), in accordance with the applicable DEQ UST Guidance and Brownfields
Program protocols. Impacted soil, if encountered, will be managed in accordance with the
“Managing On-site Soil” section of the EMP, as outlined above.
Documentation of the UST/container removal activities, UST disposal, and sampling results will be
provided to the Brownfields Project Manager upon receipt by the environmental manager.

Sub-Grade Feature/Pit:
If during redevelopment activities, an unknown sub-grade feature/pit is encountered, the
environmental manager (Will Frazier) will be notified immediately. The feature will be removed if
possible and the environmental manager will supervise exploratory excavation near the feature and
soils will be screened for potential impacts. If potential impacts are identified, the Brownfields
Project Manager will be notified, and soil samples will be collected from the area of potential impacts
and analyzed for VOCs (EPA Method 8260B), SVOCs (EPA Method 8270D) and RCRA metals (EPA
Methods 6010D and 7471B). The sample frequency will be determined based on the nature of the
feature and will be discussed with the Brownfields Project Manager prior to the collection of the
samples. If left in place, the location of the feature will be recorded for future reference. Soil
sampling results will be provided to the Brownfields Project Manager. If water is encountered within
a sub-grade pit, the procedures outlined in Part 3 will be followed. If a sub-grade feature or pit is
encountered and does not require removal for environmental, geotechnical, or construction

01671-003/00322972
27
EMP Version 2, January 2021
purposes, it will be filled with soil or suitable fill and construction will proceed.

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 below described protocols apply only to debris encountered during construction. If removal of
the debris is not necessary for construction or geotechnical reasons, the below protocols will not
apply.
If during redevelopment activities, buried waste materials are encountered, the environmental
manager (Will Frazier) will be notified immediately, and the identified waste should remain as
encountered. The Brownfields Project Manager will be notified by the environmental manager
within 24 hours of the environmental manager being notified. Following notification of the
Brownfields Project Manager, the environmental manager will supervise exploratory excavation
activities near the waste and soils will be screened for potential impacts. The waste will be
segregated from surrounding soils, inventoried and evaluated for proper management. If potential
impacts are identified, the Brownfields Project Manager will be notified, and soil samples will be
collected from the area of potential impacts and analyzed for VOCs (EPA Method 8260B), SVOCs
(EPA Method 8270D) and RCRA metals (EPA Methods 6010D and 7471B). The sample frequency will
be determined based on the nature of the debris and will be discussed with the Brownfields Project
Manager prior to the collection of the samples, and a determination will be made regarding the need
for an investigation of landfill gases. Additional laboratory analyses may be required based on the
types of waste discovered. The location of the debris will be recorded for future reference.
Documentation of the waste management activities and sampling results will be provided to the
Brownfields Project Manager upon receipt by the environmental manager.
If construction debris is identified during site grading, Terracon will evaluate whether the debris is
likely to be environmentally deleterious. If the debris appears to consist solely of former building
materials (e.g. concrete, wood, etc.), with Brownfields Program approval, the debris will be disposed
at an off-site C&D landfill. If the debris appears to consist of impacted materials, a sampling and
disposal protocol will be determined in coordination with the Brownfields Program. Areas of
suspected contaminated soil that remain at the site after excavation is complete above the NCDEQ
Residential PSRG will be managed pursuant to this plan.

Re-Use of Impacted Soils On-Site:
See Part 1 – Soil and Part 1.A for details regarding the re-use of impacted soils on the site.

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:
If impacted soils are noted at the site, the suspected soils will be isolated as soon as possible from
contact and disturbance from rain and wind until screening identification can be conducted.
Construction flagging tape attached to stakes can be used to prevent accidental movement of the
soils by earthwork operations. Covering of the soils with plastic sheeting anchored by planks,

sandbags, or an equivalent material will occur. The soils will be screened for volatile and semi-
volatile organic compounds and RCRA metals. The screening will be conducted by the on-site
environmental manager or other qualified environmental professional. The owner or contractor
may alternatively go directly to laboratory testing for identification purposes.

Screening activities can be conducted on the site and can produce preliminary results quickly. The
field tests do not produce a precise measurement of the amounts of contaminants found in the
soils but indicates whether contaminants are likely present and will generally warrant further
caution and actual measurement. If preliminary screening activities indicate a changed condition
may be present, it may be necessary to conduct laboratory testing to determine if contaminants
are present in the soil and actually pose a significant risk. Laboratory testing requires time that
varies depending on the type of test needed. In general, laboratory testing for VOCs, SVOCs and
metals can be completed in approximately 5 to 7 business days unless special arrangements are
made with the laboratory for more expensive “RUSH” results. During this time, the suspected
impacted soils should be further isolated from worker and public exposure. Special handling and
care must be taken in sampling and transporting soils for the laboratory tests to be accurate. The
workers in physical contact with suspected impacted soils should have training consistent with 29
OSHA 1910.120.

For small volumes, the soils may be placed temporarily in steel open-top drums with bolt-on lids.
After sealing, the drum should be clearly labeled with pertinent information such as “Do Not
Disturb”, sample number, date, and name of sampler. The drums should be placed in an on-site
area protected from general traffic. For larger volumes, it may be effective to place the soils into
commercial roll-off dumpsters which have been previously washed and cleaned of residues or soils
can be stockpiled on plastic sheeting. The containers will not have free-draining bottoms and
stockpiles shall be graded, bermed, or provided with an equivalent barrier where necessary to help
prevent water run-off, in accordance with Figure 1. The tops of the containers or stockpiles will
then be covered with plastic sheeting and secured against wind and rain. The commercial
containers or stockpiles should be placarded with information similar to the notation on drums.

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 1/31/2023

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;

01671-003/00322972

EMP Version 2, January 2021
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.
