EMP Version 2, June 2018
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.

2
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):
Appendix C provides the survey plat for the site included with the recorded Notice of
Brownfields Property. This plat includes the locations and dimensions of areas of potential
environmental concern along with tables listing the highest and most recent concentrations
found at each sample location above unrestricted use standards for groundwater, soil, and soil
gas.

VOCs: Naphthalene and trichloroethylene (TCE) were identified at concentrations exceeding
their respective Health-Based Residential Preliminary Soil Remediation Goals (PSRGs) at one
sample location (both at SB-15) at a depth of four feet. In May 2000, approximately 139.72 tons
of impacted soil was removed from the source area located near SB-15. The final dimensions of
the excavation measured approximately 16 feet wide by 13 feet long and 22 feet deep.

Metals: Arsenic and hexavalent chromium were identified at concentrations exceeding their
respective Health-Based Residential PSRGs at numerous locations across the site. The November
2018 Groundwater, Soil, and Soil Gas Assessment Report for the site prepared by Geosyntec
Consultants of NC, PC (Geosyntec) indicates that arsenic and hexavalent chromium can likely be
attributed to naturally-occurring background concentrations of these metals.

Cadmium was identified at a concentration exceeding its Health-Based Residential PSRGs at one
location (S-8) at a depth interval of zero to two feet.

2) Depth of known or suspected contaminants (feet):
Cadmium was detected at a concentration above the Health-Based Residential PSRG at one
sample location (S-8) at a depth interval of zero to two feet.

Naphthalene and TCE were detected at concentrations above their Health-Based Residential
PSRGs at one location (SB-15) at a depth of four feet.

3) Area of soil disturbed by redevelopment (square feet):
Approximately 22 acres (958,000 square feet).

4) Depths of soil to be excavated (feet):
In general, the northern portion of the site is anticipated to be cut approximately three feet
below the existing grade, and the southern portion of the site is anticipated to be filled to
approximately three feet above the existing grade. Depths of soil to be excavated will extend up
to approximately 13 feet in some areas (e.g., stormwater basins). A draft grading plan and
cut/fill analysis are provided in Appendix B.

8
EMP Version 2, June 2018
5) Estimated volume of soil (cubic yards) to be excavated (attach grading plan):
Approximately 59,000 cubic yards of soil are anticipated to be cut (Appendix B).

6) Estimated volume of excavated soil (cubic yards) anticipated to be impacted by contaminants:
The area around SB-15 (where naphthalene and TCE were identified above their Health-Based
Residential PSRGs) is planned to be excavated to approximately four feet. The extent of
impacted soil in this area is expected to be minimal, as the area was subject to previous
remediation through excavation and off-site disposal of impacted soil.

7) Estimated volume of contaminated soil expected to be disposed of offsite, if applicable:
Approximately 6,000 cubic yards of excess soil are anticipated, however landscape mounding is
currently being planned with the aim of zero soil export.

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).

redevelopment activities based upon soil analytical data and the preliminary grading plan,
and the NCDEQ Risk Calculator indicates that there is no unacceptable risk from soil
pathways. 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. If conditions are favorable to generation of chemically-affected
dust, the grading contractor will use typical construction measures involving a water truck
spray as necessary to address visible dust.

☐ No, explain rationale:

Field Screening of site soil
☒ Yes, describe the field screening method, frequency of field screening, person conducting
field screening:
During mass grading activities, such as excavation of the sediment basins, soil to be
disturbed or excavated at the Site will be monitored by the on-site contractor via human
sensory observations, including for staining, odors, debris, or other indications of
contaminants. If indications of affected soil are detected, then the on-site contractor will
be instructed to contact Wood personnel for further evaluation.

Following notification by the on-site contractor, Wood personnel will collect soil samples
from areas identified as potentially impacted. Soil samples will be collected manually using
a new pair of nitrile gloves and placed into a dedicated re-sealable plastic bag to be
As documented in the November 2018 Groundwater, Soil, and Soil Gas Assessment Report for the site,
the NCDEQ Risk Calculator was used to assess risk including the residential soil combined pathways,
and construction worker combined pathways. The risk calculator indicated that unacceptable risk
levels were not exceeded for the soil pathways to residents on a sitewide basis. The risk calculator
indicated that unacceptable risk levels were not exceeded for the soil pathways to construction
workers when the northern and southern parcels were calculated separately. To confirm that
unacceptable risk levels are not exceeded after grading, final grade sampling will be conducted as
described below.

screened in the field using an Organic Vapor Analyzer (OVA) equipped with a Flame
Ionization Detector (FID) with a charcoal filter. Wood personnel will screen the headspace
vapors in each bag for VOCs. Samples that exhibit a field screening FID reading (methane
excluded) exceeding 10 parts per million (ppm) will be considered for laboratory analysis of
VOCs, SVOCs, and RCRA metals. If soil is identified with constituent concentrations
exceeding those historically identified at the site, the NCDEQ Risk Calculator will be used to
assess what measures should be taken in managing that soil (e.g., capping or off site
disposal).

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, a work plan for
final grade sampling may be submitted under separate cover.
Following completion of the soil disturbance activities planned for redevelopment (i.e.
after grading and utility construction), an environmental professional will be contracted by
the PD to collect soil samples from areas that are not covered with building foundations,
sidewalks, asphalt or concrete parking and/or driveways or other similar impervious areas.
This sampling may be conducted prior or after to final topsoil placement and landscaping.
Samples will be collected at five locations, shown on Figure 3. Samples will be collected
using a decontaminated, stainless steel hand auger.

At each of the five locations, three hand auger borings will be advanced at representative
locations within 100 feet of each other, and soil from the 0-2 ft below ground surface
depth intervals will be field-composited into a single sample. The five composite samples
will be analyzed for SVOCs, RCRA metals, and hexavalent chromium using the methods
specified above.

Additionally, at each of the five locations, one grab sample will be collected from the 1-2 ft
below ground surface depth interval. These five grab samples will be analyzed for VOCs
using the analytical method specified above.

EMP Version 2, June 2018

The soil samples will be placed in a cooler with ice and shipped to a laboratory certified by
the State of North Carolina. Soil samples will be maintained under a chain-of-custody
protocol. One soil field duplicate QA/QC sample will be collected for analysis of VOCs,
SVOCs and metals. No trip blank is proposed for the soil samples. Following the completion
of the soil sampling activities, the borings will be backfilled with the soil cores and/or
bentonite to the ground surface. Excess soil cores will be spread on the ground surface at
the site. The boring locations will be recorded on a hand-held GPS unit for future
reference.

The procedures and results of final grade sampling will be presented in a report to NCDEQ.
This report will include a description of field activities, tabulated data and the laboratory
data packet with applicable Level II QA/QC documentation with “j flags” reported, and a
map showing sample locations. The report will include a comparison of the results to the
IHSB PSRGs, and assessment of the data using the NCDEQ Risk Calculator. Background
concentrations of soil constituents will be considered in evaluating soil data.

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

2) If yes, what is the estimated volume of fill soil to be imported?
Fill soil is not anticipated to be imported.

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.)

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.
Planned site grading indicates that importing fill soil will not be needed during development. In
the event that it becomes necessary to import fill soil, the PD will contact DEQ Brownfields
personnel prior to importing soil to the site and the procedures outlined in items #6 and #7
below will be implemented. A three to four inch thick layer of washed gravel will be imported
and placed below planned building slabs as part of the Vapor Intrusion Mitigation Systems at this
site. Washed gravel is not planned to be sampled prior to import. If broken concrete is to be
imported and used as an aggregate, one sample of the concrete per concrete source will be
analyzed using analyses listed below. Sampling and analysis of imported topsoil will not be
performed if topsoil is obtained from a reputable source.

6) Please check the applicable chemical analytes for fill soil samples. (Check all that apply):

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.
If the PD plans to import fill material (gravel or other materials) from the Vulcan Materials
Company quarry located near Pineville, NC or from the Martin Marietta quarry locate on Beatties
Ford Road in Charlotte, NC, no samples of the virgin import material will be collected as adequate
analytical data is available in NCDEQ 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 a permitted quarry but not pre-approved by
the Brownfields Program, one soil sample will be collected from the import fill material. A
representative soil sample will be collected from the fill material at a depth of approximately two

15
EMP Version 2, June 2018
feet using a decontaminated stainless steel hand auger. The sample will be submitted to a North
Carolina certified laboratory for the analyses indicated above. The results will be submitted to
DEQ for approval prior to importing fill.

If fill soil is obtained from an off-site property that is not a known permitted 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 the laboratory analysis indicated above at a general rate of one per 500 to 1,000 cubic yards. If
the borrow source property has been previously developed, soil samples will be collected for
laboratory analysis indicated above at a general rate of one per 400 cubic yards. Fill soil will be
considered suitable for use at the site if it does not contain compound concentrations above DEQ
IHSB PSRGs for Residential Use or typical metals concentrations which are consistent with
background levels identified at the Site. Imported organic-rich material from a commercial
landscape vendor to be used in landscape areas does not require import sampling. Imported
recycled concrete (if any) will be sampled according to #5 above.

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.
Soil is not anticipated to be exported from the site during construction. If soil export becomes
necessary, the PD may export soil to a permitted Subtitle D/municipal solid waste landfill. If PD
intends to export soil anywhere other than a permitted Subtitle D landfill, PD will contact the
DEQ Brownfields program to obtain DEQ Brownfields and DEQ Solid Waste Section approval
prior to exporting soil. Some additional characterization of soil planned for export may be
necessary.

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

16
EMP Version 2, June 2018
determined by the accepting Landfill;
☐ Landfarm or other treatment facility
☒ Use as fill at another suitable Brownfields Property – determination that a
site is suitable will require, at a minimum, that similar concentrations of the same or
similar contaminants already exist at both sites, use of impacted soil will not increase
the potential for risk to human health and the environment at the receiving Brownfields
property, and that a record of the acceptance of such soil from the property owner of
the receiving site is provided to Brownfields. Please provide additional details below.
☐ Use as Beneficial Fill off-site at a non-Brownfields Property - Please provide
documentation of approval from the property owner for receipt of fill material. This will
also require approval by the DEQ Solid Waste Section. Additional information is
provided in IR 15. Please provide additional details below.

3) Additional Details: (if transfer of soil to another property is requested above, please provide
details related to the proposed plans).

Part 1.D. MANAGEMENT OF UTILITY TRENCHES

☐ Install liner between native impacted soils and base of utility trench before filling with clean fill
(Preferred)

☒ Last out, first in principle for impacted soils (if soil can safely be reused onsite and is not a
hazardous waste), i.e., impacted soils are placed back at approximately the depths they
were removed from such that impacted soil is not placed at a greater depth than the original
depth from which it was excavated.

☐ Evaluate whether necessary to install barriers in conduits to prevent soil vapor transport,
and/or degradation of conduit materials due to direct impact with contaminants?
☐ If yes, provide specifications on barrier materials:

☒ If no, include rationale here:
The potential for vapor intrusion associated with the proposed site buildings will be managed
through a vapor intrusion mitigation system at each building. Off-site migration in utility
trenches/conduits is unlikely due to long distances. For these reasons, barriers in
conduits/trenches are not proposed.

Other comments regarding managing impacted soil in utility trenches:
In the unlikely 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 soil
and/or vapors will be performed to protect workers. If results indicate further action is warranted in

17
EMP Version 2, June 2018
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 affected soil (such as distinct unnatural color or odor, chemical odor, or filled or
previously disposed materials of concern (i.e. chemicals, tanks, drums, etc.)). If the above is noted
during utility work, the contractor will be instructed to contact the environmental consultant to
observe the suspect condition. If the environmental consultant determines the material may be
affected, the procedures outlined in Managing On-Site Soil section will be implemented. In addition,
the environmental consultant will contact the Brownfields Program Project Manager within 48 hours
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?
Recent assessment data (2019) suggests the depth to groundwater at the subject property
ranges from approximately 5 to 11 feet below the existing grade.

2) Is groundwater known to be contaminated by ☒onsite ☐offsite ☐both or ☐unknown
sources? Describe source(s):
The property was formerly occupied by an aircraft parts refurbishing facility. VOCs (including TCE
and PCE) were identified during an LSA in 1995. Reportedly, the impacts were due to leaks
emanating from a washdown pad and sump area. A source area soil excavation was performed in
2000 to remediate free product TCE impacts in Site soils. A chlorinated VOC groundwater plume
emanating from the former source area is present on-site and extends to the west of the site
beneath W.T. Harris Boulevard.

3) What is the direction of groundwater flow at the Brownfields Property?
The shallow groundwater at the site flows toward the west-northwest.

4) Will groundwater likely be encountered during planned redevelopment activities?
☐Yes ☒No
If yes, describe these activities:
Click or tap here to enter text.

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).
Accumulated water may be allowed to infiltrate to confirm whether it actually represents
groundwater rather than stormwater. In the unlikely event groundwater is encountered and
extraction is deemed necessary (i.e. dewatering from excavations or foundations) samples of
the groundwater will be collected and analyzed for VOCs. Pending completion of analytical
testing, the extracted groundwater will be stored in an on-site vessel. Following receipt of

18
EMP Version 2, June 2018
analytical data, a vacuum truck will be mobilized to the property to remove the groundwater
from the storage vessel(s) and transport the water to a permitted disposal facility.

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

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 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 Methods 6010/7471

☐ Pesticides: Specify Analytical Method Number(s):
Click or tap here to enter text.

☐ PCBs: Specify Analytical Method Number(s):
Click or tap here to enter text.

☒ Other Constituents & Analytical Method(s) (i.e. Hexavalent Chromium, Herbicides, etc.)
Please note, if field observations indicate the need for additional analyses, they should

22
EMP Version 2, June 2018
be conducted, even if not listed here.
Hexavalent Chromium by EPA Method 7199

Please provide details on the proposed methods of managing the following commonly
encountered issues during redevelopment of Brownfields Properties.
During construction activities, contractors my encounter unknown subsurface environmental
conditions (i.e. tanks, drums, or waste materials) that if encountered, will require proper
management. Prior to beginning site work, Wood 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 Wood personnel of the discovery of
unknown subsurface features or potentially affected media at the site.

In the event 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 affected soil and the disposition of affected 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 and the Brownfields program will be notified within 48-hrs of discovery of a
UST.

If a UST is encountered, the UST will be removed and transported off-site for appropriate disposal. If
the UST cannot be removed (e.g., due to geotechnical considerations), the Brownfields Program will
be notified to obtain prior approval to abandon the UST in-place (and additional sampling may be
required). In the event of an in-place abandonment, the bottom may be penetrated before
backfilling to prevent fluid accumulation.

If the UST is found to contain residual fluids, prior to removal or abandonment, the fluids will be
removed and sampled for VOCs, SVOCs, and RCRA metals and transported off-site for disposal at a
suitable facility based on the analytical results. Affected soil will be managed in accordance with the
Managing On-Site Soil section outlined in this EMP

Sub-Grade Feature/Pit:
If the feature or pit 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 backfilling to prevent fluid accumulation. If the pit is found to contain waste, 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 in this EMP, whichever is
most applicable based on the type of waste present. If the pit must be removed and the observed
waste characteristics indicate that concrete may be potentially contaminated, the concrete will be

23
EMP Version 2, June 2018
sampled and analyzed by methods specified by the disposal facility.

Buried Waste Material:
If excavation into buried waste or grossly affected soil 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 grossly-affected soil is removed. The confirmation samples will be analyzed for VOCs,
SVOCs, and the RCRA metals. Areas of suspected affected soil that remain at the site after
excavation is complete above the DEQ IHSB Residential PSRGs will be managed pursuant to this plan
and incorporated into the Brownfields plat.

Re-Use of Impacted Soils On-Site:
Please refer to the description outlined in the Managing On-Site Soil section of this EMP.

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:
