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.

Management of fugitive dust from site
☒ Yes, describe the method will include:
Significant areas of contaminated soil are not expected to be encountered or disturbed
during future Site redevelopment activities based upon previous soil sampling data and field
screening soil samples during previous assessment activities. 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 potentially 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.

EMP Version 2, June 2018
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 that may not be suitable to leave in place
in exposed areas at the Site. 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 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 Sample 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
allow alternate corrective measures described below. Suspect significantly impacted soil
excavated during grading and/or utility line installation or removal may be stockpiled and
covered in a secure area to allow construction to progress. Suspect impacted soil will be
underlain by and covered with minimum 10-mil plastic sheeting. At least one
representative sample of the soil will be collected for analysis of total VOCs, SVOCs, and
RCRA metals plus hexavalent chromium. 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 the toxicity characteristic leaching procedure (TCLP) for
those compounds that could exceed the toxicity characteristic hazardous waste criteria.
Environmental sampling will be performed in general accordance with the DEQ IHSB
Guidelines for Assessment and Cleanup (Guidelines) dated October 2015, and the most
recent versions of the U.S. Environmental Protection Agency (EPA) Region IV Science and
Ecosystem Support Division (SESD) Field Branches Quality System and Technical
Procedures guidance. Impacted soil will be handled in accordance with applicable
municipal, county, DEQ, and EPA regulations and in the manner described below based
upon the laboratory analyses:
11
EMP Version 2, June 2018
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 or are
consistent with published and Site-specific background levels, then the soil will be
deemed suitable for use as on-Site fill or as off-Site fill. The proposed location(s) for off-
Site placement of soil (other than a permitted facility) along with the receiving facility’s
acknowledgement for acceptance of the soil will be provided to DEQ for approval prior to
taking the soil off-Site.
ii. If detectable levels of compounds are found which do not exceed the DEQ
Industrial/Commercial PSRGs (other than which are attributable to sampling or laboratory
artifacts or which are consistent with Site-specific background levels for metals) and the
TCLP concentrations are below hazardous waste criteria, then the soil may be used on-
Site as fill without restriction.
iii. If detectable levels of compounds are found which exceed the DEQ
Industrial/Commercial PSRGs (other than which are attributable to sampling or laboratory
artifacts or which are consistent with background levels for metals) and the TCLP
concentrations are below hazardous waste criteria, then the soil, with DEQ’s written
approval, 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 DEQ
Industrial/Commercial PSRGs 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 in an updated survey
plat.
iv. 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 written approval to dispose of soil from the Site will be
included with the final EMP report. In the unlikely event that the sample data indicates
concentrations above TCLP hazardous waste criteria, then the soil must be 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:
☒ Volatile organic compounds (VOCs) by EPA Method 8260
☒ Semi-volatile organic compounds (SVOCs) by EPA Method 8270

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 soil disturbance for any future Site development (i.e., after
grading and utility construction), an environmental professional will be contracted to
assess the Site for areas that are not covered with clean fill soil, building foundations,
sidewalks, or asphalt or concrete parking areas and driveways, or other similar impervious
areas. If such areas exist, a plan will be prepared for final grade sampling for DEQ
Brownfields review and approval. If no such areas exist, documentation will be provided to
the DEQ Brownfields project manager.

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?
The need for off-Site import of fill soil is not anticipated at this time. However, the PD plans to
import limited amounts of organic rich topsoil from a reputable landscape material vendor for use
in proposed landscaped areas.
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.
The PD does not plan to collect samples of landscaping materials prior to placement at the Site.
DEQ Brownfields will be notified of the volume of landscaping material needed and the proposed
source of the material prior to placement in proposed landscaping areas.
The need for off-Site import of fill soil is not anticipated at this time. However, should import of
structural fill be needed for future redevelopment of the Site, the PD will follow the procedures
outlined below.
If the PD plans to import fill material from Vulcan Materials Company quarry located near
Pineville, NC or from the Martin Marietta quarry located on Beatties Ford Road in Charlotte, NC,
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.
14
EMP Version 2, June 2018
For import material from unknown borrow sources, prior to bringing fill soil to the Site, historical
information about the fill Site and a proposed sampling design will be provided to DEQ for review
and approval based upon the estimated quantity of import fill to be obtained from the fill site.
The soil sample(s) will be analyzed for VOCs, SVOCs, and RCRA metals plus hexavalent chromium.
Fill soil will be considered suitable for use at the Site if it does not contain compound
concentrations above DEQ Industrial/Commercial PSRGs or typical metals concentrations which
are consistent with background levels identified at 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
☒ Semi-volatile organic compounds (SVOCs) by EPA Method 8270

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 does not plan to collect samples of landscaping materials prior to placement at the Site.
DEQ Brownfields will be notified of the volume of landscaping material needed and the proposed
source of the material prior to placement in proposed landscaping areas.
The need for off-Site import of fill soil is not anticipated at this time. However, should import of
structural fill be needed for future redevelopment of the Site, the PD will follow the procedures
outlined below.
If the PD plans to import fill material from Vulcan Materials Company quarry located near
Pineville, NC or from the Martin Marietta quarry located on Beatties Ford Road in Charlotte, NC,
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.
For import material from unknown borrow sources, prior to bringing fill soil to the Site, historical
information about the fill Site and a proposed sampling design will be provided to DEQ for review
15
EMP Version 2, June 2018
and approval based upon the estimated quantity of import fill to be obtained from the fill site.
The soil sample(s) will be analyzed for VOCs, SVOCs, and RCRA metals plus hexavalent chromium.
Fill soil will be considered suitable for use at the Site if it does not contain compound
concentrations above DEQ Industrial/Commercial PSRGs or typical metals concentrations which
are consistent with background levels identified at the Site.
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.
Export soil is not anticipated at this time. Should soil need to be exported from the Brownfields
property during redevelopment, a sampling plan will be developed and submitted to DEQ
Brownfields for review and approval once the volume of soil for export is known. Generally, soil
samples will be collected from export soil at a rate of 1 sample per every 400-500 cubic yards of
export.
DEQ approval of the sampling plan and 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 and 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
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
16
EMP Version 2, June 2018
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:
Click or tap here to enter text.
☒ If no, include rationale here:
Impacted soil has not been identified at on the Site property.
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
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
17
EMP Version 2, June 2018
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?
The depth to groundwater at the Brownfields property is highly variable. Under purview of the
United States Army Corps of Engineers (USACE), multiple phases of assessment and remediation
have been conducted at the Site as part of investigation activities for the former Charlotte Naval
Ammunition Depot (CNAD). Based on review of March 2018 groundwater assessment results,
groundwater has been identified at depths ranging from approximately 1.6 ft bgs in the central
portions of the Site to 11.2 ft bgs in the eastern portions of the Site. However, shallow depth to
groundwater measurements may not be indicative of actual groundwater elevations and may
be locally influenced by potential groundwater mounding from injection activities and/or
partially submerged wells screens in bedrock.
In addition to available information from the USACE investigation, a January 2017 geotechnical
assessment conducted at the Brownfields property indicated approximate depths to
groundwater ranging from approximately 6.0 ft bgs in the central portions of the Site to 8.0 ft
bgs in the northwestern portions of the Site. Further, groundwater elevations may also be
influenced by topography. Land surfaces at the Brownfields property slope from a topographic
high of approximately 650.6 ft above mean sea-level in the eastern portions of the Site to
approximately 614.3 ft above mean sea-level in the western portions of the Site. In general,
topographic high areas appear to exhibit deeper depth to groundwater measurements while
topographic low areas appear to exhibit shallower depth to water measurements.
It should be noted that although available information suggest that on-Site groundwater
elevations have the potential to be highly variable, current redevelopment plans propose cut for
the topographic high portions of the Site and fill for the topographic low portions of the Site.
2) Is groundwater known to be contaminated by ☐onsite ☒offsite ☐both or ☐unknown
sources? Describe source(s):
According to historical reports, the source of the groundwater contamination was an off-Site
trichloroethylene (TCE) degreasing operation associated with the former CNAD. As part of the
USACE investigation, groundwater has been monitored on the Brownfields property. The results
of the monitoring indicated that VOC cis-1,2-dichloroethene, TCE, and vinyl chloride have
impacted on-Site groundwater at concentrations that exceed 15A NCAC 02L .0202 Groundwater
Standards (2L Standards) and DEQ Non-Residential Vapor Intrusion Groundwater Screening
Levels (GWSLs). A tabular summary of on-Site groundwater analytical data in comparison to 2L
Standards and GWSLs is included as Table 2. Groundwater data exhibiting exceedances of 2L
Standards and GWSLs from the March 2018 monitoring event are shown in Figure 3.
3) What is the direction of groundwater flow at the Brownfields Property?
18
EMP Version 2, June 2018
Groundwater at the Site flows to the west.
4) Will groundwater likely be encountered during planned redevelopment activities?
☐Yes ☒No
If yes, describe these activities:
Groundwater is not expected to be encountered during redevelopment activities. However, if
groundwater is encountered, the PD or the PD’s contractor will contact the project
environmental engineer. The environmental engineer will update the DEQ Brownfields project
manager within two business days.
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).
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.
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.
The USACE and the PD are currently in process of discussing redevelopment plans and their impact on
future groundwater monitoring and remediation. At the conclusion of these discussions, an update
will be provided to the DEQ Brownfields project manager.

at concentrations exceeding Title 15A NCAC 2B Surface Water Standards (2B Standards) for Class
C Waters.
Based on redevelopment plans, it is not anticipated that the surface water bodies or wetlands
areas will be disturbed during redevelopment activities. Should they be disturbed, or if surface
water run-off gathers in an open excavation within an area determined to be impacted during
construction activities, appropriate worker safety measures will be undertaken. 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.

Click or tap here to enter text.
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.
In the unlikely event there is evidence of potential indoor air issues (i.e. unusual odors) during future
redevelopment activities, the area will be evacuated and appropriate safety screening of the indoor
air will be performed. If warranted, safety screening procedures will include periodically screening
indoor air for volatile organic vapors with a calibrated photoionization detector and calibrated
methane gas detector. If results indicate further action is warranted, appropriate engineering
controls (such as use of industrial fans) will be implemented.

Hexavalent Chromium by EPA Method 7196
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 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 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 redevelopment 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 an underground storage tank (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 and does not require removal for geotechnical or construction purposes, it
will be abandoned in-place and construction will proceed. Where appropriate, the bottom may be
penetrated before abandonment to prevent fluid accumulation. If the UST contains residual fluids,
the fluids will be removed, sampled for VOCs, SVOCs, and RCRA metals, and transported off-Site for
disposal at a suitable facility based on the laboratory analytical results. Impacted soil will be
managed in accordance with the Managing On-Site Soil section outlined above in the EMP.
Sub-Grade Feature/Pit:
24
EMP Version 2, June 2018
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
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, and the RCRA metals plus hexavalent chromium. Areas of suspected contaminated
soil that remain at the Site after excavation is complete above the DEQ Industrial/Commercial
PSRGs will be managed pursuant to this plan and incorporated into the Brownfields plat.
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:
