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

EMP Version 2, January 2021
PART 1. Soil
1) Known or suspected contaminants in soil (list general groups of contaminants):
Soil samples were collected from areas that will be affected by planned grading activities. Soil
analytical results are included as Table 1.
A summary of the soil sampling results for the Brownfields Property are discussed below.
VOCs:
Acetone and cyclohexane were detected in samples UCMW‐4(9‐10), SB‐1(0‐1), SB‐1(10‐11), SB‐
2(0‐1), and SB‐2(10‐11), which were below their respective North Carolina Preliminary Soil
Remediation Goals (PSRG) values.
Low, estimated concentrations of benzene (0.00095J ug/Kg) and 2‐butanone (0.024J ug/Kg) were
detected in the soil sample collected from UCSB‐4, which was obtained from soils at approximately
2 to 4 feet below the ground surface (bgs). The detected benzene and 2‐butanone concentrations
were below their respective residential PSRGs.
Low concentrations of cyclohexane and xylenes were detected in the soil sample collected from
UCSB‐5, which was obtained from soils at near surface to approximately 2 feet bgs. The detected
cyclohexane and xylene concentrations were below their respective residential PSRGs.
A low, estimated concentration of toluene (0.77J ug/Kg) was detected in the soil sample collected
from UCSB‐6, which was obtained from soils at near surface to approximately 2 feet bgs. The
detected concentration of toluene was below its residential PSRG.
No other VOCs have been detected in the soil samples collected from the Brownfields Property
above their respective laboratory method detection limits.
SVOCs/PAHs:
A few polycyclic aromatic hydrocarbons (PAHs) were detected in the soil samples collected from
UCSB‐8 (obtained from soils at approximately 0‐1 foot bgs) and in the soil sample collected from
UCMW‐9 (obtained from soils at 0‐1 foot bgs). The detected PAHs were at concentrations below
their respective residential PSRGs. No other SVOCs/PAHs have been detected in the soil samples
collected from the Brownfields Property above their respective laboratory method detection
limits.
Metals:
Various concentrations of arsenic, barium, cadmium, chromium, lead, selenium and silver have
been detected in the soil samples collected from the Brownfields Property. The detected
concentrations of barium, cadmium, lead, and silver were below their respective residential PSRG
values and appear to be representative of naturally occurring background geologic conditions. The
detected arsenic concentrations ranged from 0.103J to 1.64 mg/Kg, with four samples reporting
arsenic slightly above its residential PSRG of 0.68 mg/Kg. However, the detected arsenic
concentrations are consistent with naturally occurring background levels in North Carolina, which
9
EMP Version 2, January 2021
have been documented to range from 1 to 18 mg/Kg, with a mean background concentration of
4.8 mg/Kg, as published in Elements in North American Soil by Dragun and Chekiri, 2005.
Chromium was detected in each of the soil samples collected from the Brownfields Property. The
chromium detections were compared to the residential PSRG value for chromium VI. Twenty‐one
of the twenty‐two soil samples collected from the Brownfields Property reported total chromium
concentrations in excess of the residential chromium VI PSRG value. Due to these exceedances,
United Consulting requested that the laboratory speciate these samples for trivalent (III) and
hexavalent (VI) chromium. Based on these results, it appears that the chromium detected in the
soil samples submitted for total analysis are 100% trivalent chromium, with exception of the
sample UCSB‐3 (0‐1), which reported an estimated concentration of hexavalent chromium at 1.39J
mg/K, which was above its residential PSRG of 0.31 mg/Kg. The detected concentrations of
chromium III were well below their residential PSRG of 23,000 mg/Kg. The chromium VI detection
at UCSB‐3 (0‐1) was subsequently delineated to an approximate 10’x10’ area around UCSB‐3 with
a depth of approximately 1‐foot bgs.
PCBs:
No PCBs have been detected in the soil samples collected from the Brownfields Property above
their respective laboratory method detection limits.
2) Depth of known or suspected contaminants (feet):
Low concentrations of a few VOCs and SVOCs/PAHs have been detected in the soil samples
collected from the Brownfields Property, none of which were reported at concentrations above
their respective residential PSRGs. The VOC detections were mostly identified within the 0‐4
feet bgs interval. Three soil samples also identified low concentrations of a few VOCs in the 9‐11
feet bgs interval [SB‐1 (10‐11), SB‐2 (10‐11), UCMW‐4 (9‐10)]. Of note, VOC detections were
limited to acetone in twelve of the soil samples collected from the Brownfields Property. These
acetone detections are likely indicative of false positive results. Low concentrations of
SVOCs/PAHs were identified in two soil samples in the 0‐1 foot bgs interval [UCSB‐8 (0‐1) and
UCMW‐9 (0‐1)].
Relatively low concentrations of metals have been detected in each of the soil samples collected
from the Brownfields property. Four samples collected from the 0‐1 foot bgs interval [UCSB‐3 (0‐
1), UCSB‐7 (0‐1), UCSB‐8 (0‐1) and UCMW‐5 (0‐1)] reported arsenic slightly above its residential
PSRG. As referenced above, these arsenic detections are believed to be associated with naturally
occurring background conditions. No other metals have been detected at concentrations above
their respective residential PSRGs with exception of a lone detection of chromium VI in the sample
collected from UCSB‐3 (from the 0‐1 foot bgs interval), which has been delineated to an
approximate 10’x10’ area around UCSB‐3 with a depth of approximately 1‐foot bgs.
3) Area of soil disturbed by redevelopment (square feet):
According to the cut/fill information provided by the civil engineer, the total area of the
Brownfields Property to be disturbed by redevelopment is approximately 417,500 square feet.
10
EMP Version 2, January 2021
4) Depths of soil to be excavated (feet):
According to the cut/fill plan, soils needed to be excavated to reach final grades generally range
from 0.5 to 3.5 feet across the majority of the area where cuts will be required. Some deeper
excavations will be needed along the western portion of the development area, with excavation
depths generally ranging from approximately 2 to 12.5 feet.
5) Estimated volume of soil (cubic yards) to be excavated (attach grading plan):
According to the cut/fill plan, 14,306.16 cubic yards of will need to be excavated, followed by its
subsequent re‐use as fill. According to the cut/fill analysis, approximately 6,500 cubic yards of
additional fill material will need to be imported to meet the proposed grades. The fill material is
planned to be imported from Wake Stone Corporation in Knightdale North Carolina, which is a
pre‐approved borrow source. Should fill material be needed or planned to be imported from an
alternative source that is not pre‐approved, a work plan will be submitted for approval prior to
the fill material being brought to the Brownfields Property.
6) Estimated volume of excavated soil (cubic yards) anticipated to be impacted by contaminants:
Residential PSRG exceedances have not been identified at the Brownfields Property, with
exception of arsenic and one lone detection of chromium VI. The detected arsenic
concentrations were low and are consistent with naturally concentrations. The chromium VI has
been delineated and will be remediated prior to construction via excavation and offsite disposal.
Additional soil impacts above residential PSRGs are not anticipated to be encountered.
7) Estimated volume of contaminated soil expected to be disposed of offsite, if applicable:
The area of chromium VI identified above its residential PSRG (at UCSB‐3) has been delineated to
an approximate 10’x10’ area with a depth of 1’, which equates to approximately 4 cubic yards of
soil.
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).

evidence of potential contamination. Should the above be noted during site work, the
contractor will contact the project environmental professional to observe the suspect
condition. If the project environmental professional confirms that the material may be
impacted (by observations or by screening with a PID or organic vapor analyzer [OVA]),
then soil samples will be collected and analyzed for VOCs, SVOCs, and RCRA metals as
referenced the Contingency Plan section below). In addition, the NCDEQ Brownfields
Project Manager will be contacted within 48 hours to advise them 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.):
Based on previous site assessment activities and grading plans, it is unlikely that
significant soil impacts will be encountered during redevelopment activities, and no
additional soil sampling (other than final grade sampling) is warranted unless unexpected
soil impacts are encountered. Areas of known soil impacts with concentrations above
PSRGs are currently scheduled for removal and offsite disposal. If impacted soils are
discovered during grading, the procedures for screening and sampling the soils will be
implemented as described above (field screening of soils) and in the Contingency Plan
below, and will include collecting and analyzing soil samples for VOCs, SVOCs, and RCRA
metals.

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.
Approximately 4 cubic yards of chromium VI impacted soils from the area of UCSB‐3 are planned
to be exported from the site. Based on the TCLP results for said soils, the planned disposal
location is a Subtitle D landfill. Some amounts of topsoil may need to be disposed of to facilitate
construction. Based on the overall soil data, it is anticipated that the topsoil will be acceptable to
be disposed of at a C&D landfill, pending approval of the receiving landfill.
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
17
EMP Version 2, January 2021
☐ Use as fill at another suitable Brownfields Property – determination that a
site is suitable will require, at a minimum, that similar concentrations of the same or
similar contaminants already exist at both sites, use of impacted soil will not increase
the potential for risk to human health and the environment at the receiving Brownfields
property, and that a record of the acceptance of such soil from the property owner of
the receiving site is provided to Brownfields. Please provide additional details below.
☐ Use as Beneficial Fill off‐site at a non‐Brownfields Property ‐ Please provide
documentation of approval from the property owner for receipt of fill material. This will
also require approval by the DEQ Solid Waste Section. Additional information is
provided in IR 15. Please provide additional details below.
3) Additional Details: (if transfer of soil to another property is requested above, please provide
details related to the proposed plans).

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:
Will be included in the Vapor Mitigation Plan (if needed), which will be issued under separate

EMP Version 2, January 2021
PART 2. GROUNDWATER
1) What is the depth to groundwater at the Brownfields Property?
Based on recent environmental and geotechnical investigations conducted at the development
area of the Brownfields Property, groundwater generally ranges from 2.5 to 14 feet bgs.
2) Is groundwater known to be contaminated by ☐onsite ☒offsite ☐both or ☐unknown
sources? Describe source(s):
Groundwater on the northeastern portion of the Brownfields Property has been impacted by the
eastern adjoining Raleigh Metals facility. Groundwater sampling conducted in May of 2021
identified cis‐1,2 dichloroethene, tetrachloroethene (PCE) and trichloroethene (TCE) at estimated
concentrations of 3.2, 2.0 and 1.6 micrograms per liter (µg/L), respectively, in the sample
collected from UCMW‐2. No other volatiles were identified in the groundwater samples collected
from the Brownfields Property during sampling events conducted in May and October 2021, with
exception of acetone, which appears to be a false positive result. Based on the sampling
conducted to date, groundwater impacts appear to be isolated to the east of Wildcat Branch
creek on the northeastern portion of the property in the general area of UCMW‐2. Further, no
apparent metal impacts or SVOCs/PAHs have been identified in the groundwater samples
collected from the Brownfields Property. Of note, no impacted groundwater has been identified
during recent sampling on the proposed development area of the Brownfields Property, which is
located west of Wildcat Branch creek.
3) What is the direction of groundwater flow at the Brownfields Property?
Groundwater on the western portion of the Brownfields Property has been documented to flow
to the east, towards Wildcat Branch. Based on area topography, it is anticipated that
groundwater on the eastern portion of the property flows to the west, towards Wildcat Branch.
Wildcat Brach flows to the north.
4) Will groundwater likely be encountered during planned redevelopment activities?
☒Yes ☐No
If yes, describe these activities:
Groundwater may be encountered during foundation and/or deeper utility installations.
Groundwater impacts are not present in these areas, please see below. Due to the depths of
groundwater below the proposed finished floor elevations at two proposed building locations
(buildings 3 and 4), a gravel collection layer with a chemically rated barrier (as noted in the VIM
Plan to be submitted under separate cover) is being installed to control potential water intrusion
as a conservative measure. The gravel layer will be drained to the storm sewer.
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).
It is not anticipated that contaminated groundwater will be encountered based on prior
groundwater sampling activities. If groundwater is encountered during redevelopment
activities, appropriate worker safety measures will be undertaken and groundwater will be
19
EMP Version 2, January 2021
allowed to re‐infiltrate for approximately 24 hours (if it does not affect the construction
schedule). No soil will be added to the excavation during that time period. If accumulated water
remains in an excavation after allowing time to re‐infiltrate, samples of the accumulated water
will be collected and analyzed for VOCs, SVOCs, and the RCRA metals to determine if
contaminants are present, unless existing groundwater data for the area indicates that
additional sampling and characterization are unnecessary. Accumulated water that contains
contaminants above NCAC 2B Surface Water Standards will be containerized and disposed at an
off‐site permitted facility. Accumulated water that does not contain contaminants above NCAC
2B Surface Water Standards will be managed on the site or discharged to surface water or the
storm sewer in accordance with municipal, state and federal requirements.
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 To our knowledge,
the surface water is not known to be contaminated. Further, no impacts have been identified in
the sediment samples collected from the onsite creek. Additionally, surface water is not

20
EMP Version 2, January 2021
anticipated to be encountered during construction.
4) Will workers or the public be in contact with surface water during planned redevelopment
activities? ☐ Yes ☒ No
No contact with surface water is anticipated in connection with the PD’s redevelopment
activities, but portions of Wildcat Branch are unprotected and accessible to the public and/or
workers.
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):
No encountering of contaminated surface water is anticipated based current redevelopment
plans. Excavations and trenches in areas where potentially impacted soils could be encountered
and near property boundaries shall be graded, bermed, or provided with an equivalent barrier,
where necessary, to help prevent stormwater from entering excavations and stormwater run‐off
from leaving the site boundaries. If stormwater or water from an unidentified source collects in
excavation areas, appropriate worker safety measures will be undertaken and water will be
allowed to infiltrate for approximately 24 hours (if it does not affect the construction schedule).
If accumulated water remains in an excavation after allowing time to infiltrate, samples of the
accumulated water will be collected and analyzed for VOCs (EPA Method 8260), SVOCs (EPA
Method 8270), and RCRA metals. Accumulated water that contains contaminants above NCAC
2B Surface Water Standards will be containerized and disposed at an off‐site permitted facility.
Accumulated water that does not contain contaminants above NCAC 2B Surface Water Standards
will be managed on the site or discharged to surface water or the storm sewer in accordance with
municipal, state and federal requirements.
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 since there are no known impacts to sediment in the on‐site Wildcat Branch.
Further, the PD’s redevelopment plans do not include activities in Wildcat Branch. No other natural
drainage features are located on the site.

EMP Version 2, January 2021
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. See Figure 13
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:
Recent soil gas testing conducted at the Brownfields Property identified TCE in the samples
collected from UCSV‐U1 and UCSV‐B1 at concentrations of 39 and 38 micrograms per cubic meter
(µg/m³), which is above its residential SGSL of 14 µg/m³. No other constituents were identified at
concentrations in excess of their SGSLs with exception of 1,3‐butadine, which was reported at 20
µg/m³, above its residential SGSL of 3.1 µg/m³. The locations of these samples and their
corresponding analytical results are shown on the attached Figure 13.
These soil gas samples were collected from approximately 3 feet below the existing grade,
indicating that contaminated soil vapor may be encountered during redevelopment activities. If
contaminated vapors are detected during grading or construction activities involving excavation
of subsurface utility trenches, foundations or basement structures, the project environmental
professional will be notified to assess the presence of the vapors with a PID. If vapors do not
readily dissipate, soil samples may be obtained and analyzed for VOCs and SVOCs to evaluate the
source of the vapors and appropriate worker safety measures will be employed (such as fans) to
allow the workers to safely complete their work.
Approximately 3 feet below the existing grade
22
EMP Version 2, January 2021
PART 6. SUB‐SLAB SOIL VAPOR

identified in exterior soil gas samples that were collected from approximately 3‐feet below the
existing grade.
4) Will workers encounter contaminated sub‐slab soil vapor during planned redevelopment
activities? ☐ Yes ☒ No ☐ Unknown
☒ If no, include rationale here:
As referenced above, there are no existing structures located on the Brownfields Property where
potential sub‐slab soil vapor contamination could be encountered. In the unlikely event that
sub‐slab repairs are needed post foundation installations, the below measures will be followed.
5) In the event that contaminated soil vapor is encountered during redevelopment activities, list
activities for management of such contact
If contaminated vapors are detected during grading or construction (or post construction)
activities involving excavation of subsurface utility trenches or basement structures, the project
environmental professional will be notified to assess the presence of the vapors with a PID. If
vapors do not readily dissipate, soil samples may be obtained and analyzed for VOCs and SVOCs
to evaluate the source of the vapors and appropriate worker safety measures will be employed
(such as fans) to allow the workers to safely complete their work.
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.
23
EMP Version 2, January 2021

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.
Although not anticipated, in the event contaminated indoor air is encountered during
redevelopment activities, the work area will be evacuated, and appropriate safety screening of the
vapors will be performed. If results indicate further action is warranted, appropriate engineering
controls (such as use of industrial fans) will be implemented.
24
EMP Version 2, January 2021
Notification to DEQ Brownfields Project Manager, UST Section, Fire Department, and/or other
officials, as necessary and appropriate, is required when new potential source(s) of
contamination are discovered. These Notification Requirements were outlined on Page 1 of this
EMP.
Should potentially impacted materials be identified that are inconsistent with known site
impacts, the DEQ Brownfields Project Manager will be notified and a sampling plan will be
prepared based on the EMP requirements and site‐specific factors. Samples will generally be
collected to document the location of the potential impacts.
Check the following chemical analysis that are to be conducted on newly identified releases:
☒ Volatile organic compounds (VOCs) by EPA Method 8260
☒ Semi‐volatile organic compounds (SVOCs) by EPA Method 8270
☒ Metals RCRA List (8) (arsenic, barium, cadmium, chromium, mercury, lead, selenium and
silver)
EPA Method 6010 and 7473
☐ 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 & 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 EPA Method 7199
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 must be able to recognize when conditions change
at the site so conditions can be properly managed. In the event such conditions are encountered
during site redevelopment activities, the environmental actions noted below will be taken.
During soil disturbance, workers and contractors will observe soils for evidence of potential impacts.
Evidence of potential impacts includes odors, soil discoloration, or discovery of a tank, drums, a drain
field, or buried debris. Should any of the above be noted during site work, the contractor will contact
the project environmental professional to observe the suspect condition. If the project
environmental professional confirms that the material may be impacted, then the procedures below
will be implemented. In addition, the NCDEQ Brownfields project manager will be contacted within
48 hours of discovery.
If evidence of potential soil impacts is encountered during grading and/or the 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 to be taken.
25
EMP Version 2, January 2021
Suspect soil excavated during grading and/or utility installation or removal may be stockpiled in a
secure area onsite in accordance with Figure 1 below (NCBP Diagram for Temporary Containment of
Impacted or Potentially Impacted Soil). At least one representative sample of the soil will be
collected for analysis of VOCs by EPA Method 8260, SVOCs by EPA Method 8270, and RCRA metals
by EPA method 6010/7473 and 7199 for hexavalent chromium.
Underground Storage Tanks:
If USTs are discovered on the site during construction activities and impacts uniquely associated
with a UST release are identified, the UST and petroleum‐impacted soil will be addressed as
required by either the NCDEQ Brownfields Program or the NCDEQ UST Section.
Sub‐Grade Feature/Pit:
If a sub‐grade feature, structure, or pit is encountered during construction, it will be inspected for
the presence of waste fluids. If waste fluids are present, they will be removed, profiled and disposed
at a permitted facility by the contractor. If the structure does not require removal for construction
purposes, it will be filled with soil or suitable fill and construction will proceed. Where appropriate,
the bottom may be penetrated before backfilling to prevent rainwater accumulation. If waste is
present, the waste will be set aside in a secure area, sampled as required by NCDEQ and disposed at
an off‐site location. If a concrete structure must be removed and the observed waste characteristics
indicate the concrete may contain hazardous constituents, 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 landfilled material is encountered at the site during construction activities, the nature and extent
of the buried material will be evaluated (e.g., by test pits) and NCDEQ will be notified to discuss the
appropriate course of action. Site debris will be segregated as needed, and disposed or recycled at
an approved facility, or reused on the site as beneficial fill.
If a drum is encountered during construction, the contents will be identified by the contractor, and
if appropriate, the contents of the drum profiled and disposed at a permitted facility. The protocols
noted above for soils will be followed for areas near any drums that are encountered.
If buried piping is encountered and must be removed to allow construction to proceed, the
contractor will inspect the pipe for fluids, collect and sample fluids where appropriate, and look for
evidence of a release using field screening methods (visual and olfactory). If a release is suspected,
NCDEQ will be contacted to discuss the appropriate course of action.
Re‐Use of Impacted Soils On‐Site:
26
EMP Version 2, January 2021
Soil sampled in accordance with the preceding paragraphs will be managed in the manner described
below based on laboratory analyses:
1. If detectable levels of compounds are found that do not exceed DEQ IHSB Residential PSRGs
(or, for metals, levels that are consistent with site‐specific naturally occurring
concentrations) and the TCLP concentrations (if applicable) are less than hazardous waste
criteria, then the soil may be used on the site as fill without conditions.
2. If detectable levels of compounds are found that exceed NCDEQ IHSB Residential PSRGs (or,
for metals, levels that exceed site‐specific naturally occurring concentrations) and the TCLP
concentrations (if applicable) are less than hazardous waste criteria, then the soil, with
NCDEQ’s written approval, may be used on the site as fill below an impervious surface or
two feet of clean fill.
3. Soil may be transported to a permitted facility such as a landfill provided that the soil is
accepted at the disposal facility.
4. If excavation of impacted soil occurs, confirmation sampling will be conducted for purposes
of recording areas of impacts remaining at the site. It is anticipated that confirmation
samples will be collected at regular intervals along the base and sidewalls of a given
excavation. Base samples will not be collected if the estimated groundwater elevation is
within 1.5 ft. of the excavation floor. The confirmation samples will be analyzed for VOCs,
SVOCs, and RCRA metals.
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:
