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
So that the EMP provides value in protecting brownfields eligibility and public health, the
preparer shall ensure that the following steps have been completed prior to submitting the
EMP for review. Any EMP prepared without completing these steps is premature.
® Site sampling and assessment that meets Brownfields' objectives is complete and has
been reviewed and approved by the Brownfields Project Manager.
® Specific redevelopment plans, even if conceptual, have been developed for the project,
submitted and reviewed by the Brownfields Project Manager.
EMP Version 2, June 2018

Please submit, along with the completed EMP form, the following attachments, as relevant
and applicable to the proposed redevelopment:
® A set of redevelopment plans, including architectural/engineering plans, if available; if
not conceptual plans may suffice if updated when detailed plans are drafted.
❑ A figure overlaying redevelopment plans on a map of the extent of contamination for
each media.
® Site grading plans that include a cut and fill analysis.
❑ A figure showing the proposed location and depth of impacted soil that would remain
on site after construction grading.
❑ Any necessary permits for redevelopment (i.e. demolition, etc.).
® A detailed construction schedule that includes timing and phases of construction.
® Tabulated data summaries for each impacted media (i.e. soil, groundwater, soil gas,
etc.) applicable to the proposed redevelopment.
❑ Figures with the sampling locations and contamination extents for each impacted media
applicable to the proposed redevelopment.
❑ A full final grade sampling and analysis plan, if the redevelopment plan is final.
❑ If known, information about each proposed potential borrow soil source, such as aerial
photos, historic site maps, historic Sanborn maps, a site history, necessary for
brownfields approval.
❑ Information and, analytical data if required, for quarries, or other borrow sources,
detailing the type of material proposed for importation to the Brownfields Property.
❑ A work plan for the sampling and analysis of soil to be brought onto the Brownfields
Property. Refer to Issue Resolution 15 in Brownfields Program Guidelines.
❑ A map of the Brownfields Property showing the location of soils proposed for export
and sampling data from those areas.
❑ If a Vapor Mitigation System is required by the Brownfields Program, the Vapor
Intrusion Mitigation System (VIMS) plan will be signed and sealed by a NC Professional
Engineer. The VIMS Plan may also be submitted under separate cover.

PART 1. Soil — Please fill out the information below, using detailed site plans, if available, or estimate
using known areas of contaminated soil and a conceptual redevelopment plan. Provide a figure
overlaying new construction onto figure showing contaminated soil and groundwater locations.
1) Known or suspected contaminants in soil (list general groups of contaminants):
Multiple soil sampling events have been completed at the Brownfields property since 2017. The
most recent sampling event was completed by Hart & Hickman, PC in January 2019 and the work
plan was requested and approved by the North Carolina Department of Environmental Quality
(DEQ) Brownfields Program. A tabular summary of the January 2019 soil analytical data in
comparison to DEQ's Inactive Hazardous Sites Branch (IHSB) Preliminary Soil Remediation Goals
(PSRGs) is included as Table 1 and soil sample locations are shown in Figure 2. Additional tabular
summaries of available soil analytical data and associated sampling locations are included in
Appendix D. A brief summary of the soil assessment results is provided below.
Volatile Organic Compounds (VOCs)
Assessment activities conducted on the Brownfields property did not identify VOCs at
6
EMP Version 2, June 2018

concentrations above laboratory method detection limits.
Semi -Volatile Organic Compounds (SVOCs)
Assessment activities conducted at the Brownfields property indicated a low level of benzoic acid
at a concentration above the laboratory method detection limit, but below Residential Maximum
Soil Contaminant Concentrations (MSCCs). The sample was collected during post -excavation soil
sampling following removal of a former heating oil aboveground storage tank (AST) in March
2018.
Total Petroleum Hydrocarbons (TPH)
Assessment activities conducted at the Brownfields property identified a concentration of diesel -
range TPH (270 milligrams per kilogram [mg/kg]) that exceeds the DEQ Action Level of 100
mg/kg. However, soil associated with this sample were excavated during removal of the former
heating oil AST mentioned above. Post -excavation soil sampling analytical data did not indicate
exceedances of Residential MSCCs.
Pesticides
Assessment activities conducted on the Brownfields property have identified low levels of
organochlorine pesticides at concentrations above laboratory method detection limits, but
below DEQ Residential PSRGs.
Metals
Assessment activities conducted on the Brownfields property have identified arsenic at
concentrations exceeding Residential and Industrial/Commercial PSRGs. Most of the arsenic
detections appear to be naturally occurring, but potentially elevated arsenic concentrations (up
to 26 mg/kg) were evaluated to be acceptable using the February 2018 DEQ Risk Calculator. The
results of the risk calculations indicated no exceedances of acceptable cumulative risk levels for a
resident, non-residential worker, or construction worker. No other metals have been detected
at concentrations exceeding Residential PSRGs. Risk calculations are included in Appendix E.
2) Depth of known or suspected contaminants (feet):
0 to 6 ft below ground surface (bgs)
3) Area of soil disturbed by redevelopment (square feet):
Based on cut -fill analysis (Appendix B), an approximate area of 163,700 sq ft is expected to be
disturbed during redevelopment activities.
4) Depths of soil to be excavated (feet):
Proposed grading activities are expected to include excavations of up to approximately 6 ft bgs in
the central portion of the Witherspoon Nursery West property to reach the final proposed grade.
Construction of building footers, foundations and utility installations may require additional
excavations of up to 3 to 5 ft bgs.
EMP Version 2, June 2018

5) Estimated volume of soil (cubic yards) to be excavated (attach grading plan):
Approximately 10,000 cubic yards of soil are planned to be excavated and re -used on -site as
beneficial fill during grading activities.
6) Estimated volume of excavated soil (cubic yards) anticipated to be impacted by contaminants:
Based on risk calculator results, excavation of impacted soil is not anticipated. Risk calculations
are included in Appendix E.
7) Estimated volume of contaminated soil expected to be disposed of offsite, if applicable:
Topsoil (approximately 2,300 cubic yards) may be disposed off -site.
Part 1.A. MANAGING ONSITE SOIL
If soil is anticipated to be excavated fromthe 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).

4) Please describe the following action(s) to be taken during and following excavation and
management of site soils:
Management of fugitive dust from site
® Yes, describe the method will include:
The grading contractor will consider conditions such as wind speed, wind direction, and
moisture content of soil during soil grading and stockpiling activities to minimize dust
generation. In the unlikely event that contaminated soil is encountered during Site
redevelopment that requires excavation, particular attention will be paid by contractors to
implement dust control measures as needed based on Site and atmospheric conditions (i.e.
by controlled water application, hydro -seeding, and/or mulch, stone, or plastic cover).
Potentially impacted soil will be managed as described below.
❑ No, explain rationale:
Click or tap here to enter text.
Field Screening of site soil
® Yes, describe the field screening method, frequency of field screening, person conducting
field screening:
During soil disturbance at the Site, the workers or contractors will observe soils for
evidence of potential significantly impacted soil, such as a distinct unnatural color, strong
odor, or filled or previously disposed materials of concerns (i.e. chemicals, tanks, drums,
etc.). Should the above be noted during Site work, the contractor will contact the project
environmental engineer to observe the suspect condition. If the project environmental
engineer confirms that the material may be impacted, then the procedures below will be
implemented. In addition, the environmental engineer will contact the DEQ Brownfields
project manager within two business days to advise that person of the condition.
❑ No, explain rationale:
Click or tap here to enter text.
Soil Samole Collection
❑ Yes, describe the sampling method (e.g., in -situ grab, composite, stockpile, etc.):
Click or tap here to enter text.
® No, explain rationale:
Collection of additional soil samples is not anticipated based on results of previous Site
assessment activities. If significant soil impact is encountered during grading and/or
installation or removal of utilities, excavation will proceed only as far as needed to allow
grading and/or construction of the utility to continue and/or only as far as needed to
10
EMP Version 2, June 2018

allow alternate corrective measures described below. Suspect significantly impacted soil
excavated during grading and/or utility line installation or removal will be underlain by
and covered with minimum 10-mil plastic sheeting and stockpiled and covered in a secure
area to allow construction to progress. At least one representative sample of the soil will
be collected for analysis of total VOCs, SVOCs, and RCRA metals. If the results of analysis
of the sample indicate that the soil could potentially exceed toxicity characteristic
hazardous waste criteria, then the soil will also be analyzed by TCLP for those compounds
that could exceed the toxicity characteristic hazardous waste criteria. Please note that
total chromium concentrations detected at the Site will be considered trivalent chromium
as no hexavalent chromium has been detected at the Site and there is no indication that
historical operations included the use of hexavalent chromium containing materials.
Impacted soil will be handled in the manner described below based upon the laboratory
analyses: i. If no organic compounds are detected in
a sample (other than which are attributable to sampling or laboratory artifacts) and
metals are below Residential PSRGs, meet risk levels based on the February 2018 DEQ
Risk Calculator, or are consistent with Site -specific background levels, then the soil will be
deemed suitable for use as on -Site fill. For soil export, the proposed location(s) for off -
Site placement of soil (other than a permitted facility) along with the receiving facility's
written approval for acceptance of the soil will be provided to DEQ for approval prior to
taking the soil off -site
If detectable levels of
compounds are found which exceed DEQ acceptable risk levels based on the February
2018 DEQ Risk Calculator (other than which are attributable to sampling or laboratory
artifacts or which are consistent with background levels for metals), the TCLP
concentrations are below hazardous waste criteria, then the soil may be used on -Site as
fill below an impervious surface, or at least 2 ft of compacted clean soil. If the impacted
soil with concentrations above acceptable risk levels is moved to an on -Site location, its
location and depth will be documented, covered with a geotextile fabric so that its
location can be identified if encountered in the future, and its location will be provided to
DEQ.
iii. Impacted soil may be transported to a permitted facility such as a landfill provided that
the soil is accepted at the disposal facility. If soil is transported to a permitted facility, the
permitted facility's documentation for disposal of soil from the Site will be included with
the final report. In the unlikely event that the sample data indicates concentrations
above TCLP hazardous waste criteria, then the soil must be pre-treated or transported off -
site to a permitted disposal facility that can accept or treat hazardous waste.
If soil samples are collected for analysis, please check the applicable chemical analytes:

Part 1.113. 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
2) If yes, what is the estimated volume of fill soil to be imported?
According to the grading plan and cut -fill analysis, approximately 12,000 cubic yards of
structurally suitable import material will be needed to achieve proposed final grade elevations.
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.)
Up to approximately 16 feet of fill will be placed in the north -central portion of the Witherspoon
Nursery West property. According to cut -fill analysis results, fill depths across the site range from
no fill (i.e. on -grade) to 16 ft.
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:
The borrow source for fill material is unknown at this time. Upon determination of the borrow
source, DEQ will be notified and the procedures outlined below will be implemented.
5) PRIOR TO ITS PLACEMENT AT THE BROWNFIELDS PROPERTY, provide a plan to analyze fill
soil to demonstrate that it meets acceptable standards applicable to the site and can be
approved for use atthe Brownfields property.
The PD plans to import limited amounts of organic rich topsoil from a commercial landscape
material vendor for use in proposed landscaped areas. The PD does not plan to collect samples
of landscaping materials prior to placement at the site. DEQ Brownfields will be notified of the
13
EMP Version 2, June 2018

volume of landscaping material needed and the proposed source of the material prior to
placement in proposed landscaping areas. See No. 7 below for details outlining the proposed
plan to demonstrate import soil meets acceptable standards to the site.
6) Please check the applicable chemical analytes for fill soil samples. (Check all that apply):
® Volatile organic compounds (VOCs) by EPA Method 8260

7) The scope of work for import fill sampling may be provided below or in a Work Plan
submitted separately for DEQ review and approval. Attach specific location maps for in -situ
borrow sites. If using a quarry, provide information on the type of material to be brought
onto the Brownfields Property.
The PD will follow the procedures outlined below to demonstrate import soil meets acceptable
standards applicable to the Site.
If the PD plans to import virgin fill material from the Wake Stone Corporation quarry located in
Knightdale, North Carolina, no samples of the import material will be collected as adequate
analytical data is available in the DEQ Brownfields database to demonstrate material from these
facilities is suitable for use as structural fill at a Brownfields property.
If fill soil is obtained from an off -Site property that is not a known permitted quarry or is recycled
material from the Wake Stone Corporation quarry, a sampling plan will be developed and
submitted for DEQ review. DEQ approval of the sampling plan and analytical results will be
obtained prior to transporting import soil to the Site. The specific sampling rate will be outlined in
the aforementioned sampling plan. However, if the proposed borrow source has not been
previously developed (i.e., virgin land), soil samples will be collected for laboratory analyses
indicated above at a general rate of one per 1,000 cubic yards. If the borrow source property has
been previously developed, soil samples will be collected for laboratory analyses indicated above
at a general rate of approximately one per 500 cubic yards. Fill soil will be considered suitable for

EMP Version 2, June 2018

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 2,300 cubic yards of topsoil are expected to be exported. Prior to off -site
disposal, topsoil will be sampled in general accordance with DEQ's Inactive Hazardous Sites
Branch (IHSB) Guidelines for Assessment and Cleanup dated October 2015, and sampling
procedures outlined in H&H's November 16, 2018 Brownfields Assessment Work Plan. The work
plan was approved by DEQ Brownfields in an email dated December 3, 2018.
Samples will be collected from export soil at a rate of 1 sample per every 500 cubic yards of
export. Export soil samples will be collected directly into laboratory -supplied sample containers.
The sample containers will be labeled with the sample identification, date, and requested
analysis, and placed in a laboratory supplied cooler and iced. The export soil samples will be
delivered to a North Carolina certified laboratory under standard chain of custody protocols for
analysis of VOCs by EPA Method 8260, SVOCs by EPA Method 8270, RCRA metals by EPA
Methods 6020/7471, and organochlorine pesticides by EPA Method 8081.
DEQ approval of the analytical results will be obtained prior to transporting export soil from the
Site. Based on analytical results of soil samples collected from the export soil, the soil will be
transported off -Site to a suitable location. The PD will notify DEQ Brownfields of the location
receiving the export soil. If not a permitted facility, DEQ Brownfields approval and written
approval from the receiving facility will be obtained prior to transporting the soil off -Site.
2) To what type of facility will the export Brownfields soil be sent?
© Subtitle D/Municipal Solid Waste Landfill (analytical program to be determined by
landfill)
® Permitted but Unlined Landfill (i.e. LCID, C&D, etc.) Analytical program to be
determined by the accepting Landfill;
® Landfarm or other treatment facility
® 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
15
EMP Version 2, June 2018

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
provided in IR 1S. 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).
The environmental engineer will contact DEQ Brownfields to obtain DEQ Brownfields and DEQ
Solid Waste approval prior to exporting soil to a non-Brownfields property.
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
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?
❑ Ifyes, provide specifications on barrier materials:
Click or tap here to enter text.
® If no, include rationale here:
Impacted soil does not exceed acceptable risk levels based on the February 2018 DEQ Risk
Calculator.
Other comments regarding managing impacted soil in utility trenches:
Although not anticipated, in the event contaminated soil and/or vapors are encountered in utility
trenches during redevelopment activities, the trench will be evacuated and appropriate safety
screening of the vapors will be performed to protect workers. If results indicate further action is
warranted in response to vapors to protect workers, appropriate engineering controls (such as use of
industrial fans) will be implemented.
The contractor and workers will observe soil for potential impacts during utility installation activities.
Evidence of potential significant impacted soil includes a distinct unnatural color, strong odor, or filled
or previously disposed materials of concerns (i.e. chemicals, tanks, drums, etc.). Should the above be
16
EMP Version 2, June 2018

noted during utility work, the contractor will contact the project environmental engineer to observe
the suspect condition. If the project environmental engineer confirms that the material may be
impacted, then the procedures outlined Managing On -Site Soil above will be implemented. In
addition, the environmental engineer will contact the DEQ Brownfields project manager within two
business days to advise that person of the condition.
PART 2. GROUNDWATER — Please fill out the information below.
1) What is the depth to groundwater at the Brownfields 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., dewateringof groundwater from excavations or
foundations, containerizing, offsite disposal, discharge to sanitary sewer, NPDES permit, or
sampling procedures).
Although not anticipated at this time, appropriate worker safety measures will be undertaken if
groundwater gathers in an open excavation within an area determined to be impacted during
construction activities. The accumulated water will be allowed to evaporate, tested and
disposed off -Site (if impacted), or tested and discharged to the storm sewer (if not impacted
above DEQ surface water standards) in accordance with applicable municipal and State
regulations for erosion control and construction stormwater control.

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/orother
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 6020 and EPA Method 7471
© Pesticides: Specify Analytical Method Number(s):
Organochlorine pesticides (OCPs) by EPA Method 8081
21
EMP Version 2, June 2018

❑ PCBs: Specify Analytical Method Number(s):
❑ 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.
Please provide details on the proposed methods of managing the following commonly
encountered issues during redevelopment of Brownfields Properties.
During construction activities, contractors may encounter unknown sub -surface environmental
conditions (i.e. tanks, drums, or waste materials) that if encountered, will require proper
management. Prior to beginning Site work, H&H will attend a pre -construction meeting with the PD
and the redevelopment contractors to discuss the DEQ approved EMP and various scenarios when it
would be appropriate and necessary to notify H&H of the discovery of unknown subsurface features
or potentially impacted media at the Site.
In the event that such conditions are encountered during site development activities, the
environmental actions noted below will be used to direct environmental actions to be taken during
these activities and sampling data for potentially impacted soil and the disposition of impacted soil
will be provided to DEQ when the data becomes available.
Underground Storage Tanks:
In the event a UST or impacts associated with a UST release are discovered at the Site during
redevelopment activities, the UST and/or UST related impacts will be addressed through the
Brownfields Program.
If a UST is encountered, the UST will be removed and transported off -Site for disposal at a suitable
facility. If the UST contains residual fluids, the fluids will be sampled for VOCs, SVOCs, and RCRA
metals, and transported off -Site for disposal at a suitable facility based on the laboratory analytical
results prior to removing the UST from the ground. If a UST is encountered that cannot be removed
or does not require removal for geotechnical or construction purposes, with DEQ prior approval it
will be abandoned in -place and construction will proceed. Impacted soil in the vicinity of the UST
will be managed in accordance with the Managing On -Site Soil section outlined above in the EMP. If
a UST will be left in -place, DEQ Brownfields will be notified.
Sub -Grade Feature/Pit:
If a sub -grade feature or pit is encountered and does not require removal for geotechnical or
construction purposes, it will be filled with soil or suitable fill and construction will proceed. Where
appropriate, the bottom may be penetrated before back filling to prevent fluid accumulation. If the
pit has waste in it, the waste may be set aside in a secure area and will be sampled for waste
disposal purposes for TCLP VOCs, TCLP SVOCs, and TCLP metals and disposed off -site at a permitted
facility or the waste will be managed in accordance with the Managing On -Site Soil section outlined
above in the EMP, whichever is most applicable based on the type of waste present. If the pit must
be removed and the observed waste characteristics indicate the concrete may potentially be
22
EMP Version 2, June 2018

contaminated to a significant degree, the concrete will be sampled and analyzed by methods
specified by the disposal facility.
Buried Waste Material:
If excavation into buried wastes or significantly impacted soils occurs, the contractor is instructed to
stop work in that location and notify the environmental consultant. The environmental consultant
will review the materials and collect samples if warranted. In this event, confirmation sampling will
be conducted at representative locations in the base and the sidewalls of the excavation after the
waste or significantly impacted soil is removed. The confirmation samples will be analyzed for
VOCs, SVOCs, RCRA metals, and OCPs. Areas of suspected contaminated soil that remain at the Site
after excavation is complete above the DEQ IHSB Industrial/Commercial PSRGs will be managed
pursuant to this plan.
Re -Use of Impacted Soils On -Site:
Please refer to description outlined in the Managing On -Site Soil section of the EMP above.
If unknown, impacted soil is identified on -site, management on -site can be considered after the
project team provides the necessary information, outlined in Part 1.A. Item 11, for Brownfields
Project Manager approval prior to final placement on -site.
If other potential contingency plans are pertinent, please provide other details or scenarios as
needed below:

Notes:
1. If lead concentrations were entered in the exposure point concentration tables, see the individual calculator sheets for
lead concentrations in comparison to screening levels. Note that lead is not included in cumulative risk calculations.
2. * = If concentrations in groundwater exceed the NC 2L Standards or IMAC, or concentrations in surface water exceed
the NC 2B Standards, appropriate remediation and/or institutional control measures will be necessary to be eligible for a
risk -based closure.

* - Note that inhalation on this calculator refers to outdoor inhalation of volatiles and particulates, not indoor inhalation associated with vapor intrusion.
* * - Note that the EPA has no consensus on reference dose or cancer slope factor values for lead, therefore it is not possible to calculate cancer risk or hazard quotient. Lead concentrations are compared to the EPA screening level of 800 mg/kg
for commercial/industrial soil.
