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.

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.

overlaying new construction onto figure showing contaminated soil and groundwater locations.
1) Known or suspected contaminants in soil (list general groups of contaminants):
Tabular summaries of available soil sample analytical data in comparison to the North Carolina
Department of Environmental Quality (DEQ) Inactive Hazardous Sites Branch (IHSB) Preliminary
Soil Remediation Goals (PSRGs) and DEQ Underground Storage Tank (UST) Section Action Levels
(where applicable) are included as Table 1A and Table 1B. A soil sample location map is provided
as Figure 3A, an in situ soil sample location map is provided as Figure 3B, and a soil sample
compounds concentration map is provided as Figure 3C. A brief summary of the soil assessment
results is provided below.
7
EMP Version 2, June 2018
Volatile Organic Compounds (VOCs)
Laboratory analytical results indicate that low levels of several petroleum‐related compounds
were detected at concentrations above the laboratory method detection limits, but below the
DEQ IHSB PSRGs in an area of surficial staining in the northeastern portion of the Site. In
addition, a trace level of 1,4‐dichlorobenzene (0.0025 mg/kg) was detected at a concentration
above the laboratory method detection limit, but below DEQ IHSB PSRGs in a soil sample (SB‐4)
collected beneath the slab of the dye house in the western portion of the Site. Aside from trace
levels of acetone, no other VOCs detected above laboratory method detection limits in soil
samples collected at the Site.
Semi‐Volatile Organic Compounds (SVOCs)
As shown in Table 1B and in Figure 3C, laboratory analytical results indicate that low levels of
benzo(a)pyrene (up to 0.22 J mg/kg) were detected at concentrations above the DEQ IHSB
Residential PSRG in in situ soil characterization soil samples EX‐18 and EX‐23. No other SVOCs
were detected at concentrations above the PSRGs in soil samples collected at the Site.
Total Petroleum Hydrocarbons (TPH)
As shown in Table 1A and in Figure 3C, TPH as diesel range organics (480 mg/kg) was detected at
a concentration above the DEQ UST Section Action Level of 100 mg/kg in soil sample SS‐5
collected in an area of surficial staining located in the northeastern portion of the Site. TPH
fractions were not detected above the laboratory method detection limits in other soil samples
collected at the Site.
Metals
As expected, several metals have been detected at concentrations above the laboratory method
detection limits in soil samples collected at the Site. The detected metals concentrations appear
to be consistent with naturally occurring levels in Site area soil and are considered to represent
background concentrations.
2) Depth of known or suspected contaminants (feet):
Soil samples containing benzo(a)pyrene at concentrations exceeding the Residential PSRG were
collected from depths ranging from 0 to 3 feet below grade. It is estimated that diesel impacted
soil is limited to shallow soil (less than 2 ft bgs) in an approximate 650 sq ft area in the
northeastern portion of the Site. The locations at the Site with compound concentrations above
the applicable screening criteria are shown in Figure 3C.
3) Area of soil disturbed by redevelopment (square feet):
Grading will generally be conducted across the entire Site prior to construction (approximately
186,500 sq ft).
4) Depths of soil to be excavated (feet):
Cut depths in the western portion of the Site will extend to depths ranging from less than 1 ft to
approximately 8.5 ft.
8
EMP Version 2, June 2018
5) Estimated volume of soil (cubic yards) to be excavated (attach grading plan):
A copy of the most recent version of the cut‐fill analysis is provided as Appendix B. Grading and
construction activities for the proposed redevelopment at the Site will generate approximately
8,000 cubic yards of soil that will likely need to be transported off‐Site to achieve proposed final
grade elevations. The export soil volume includes approximately 5,600 cubic yards of
geotechnically unsuitable undocumented urban fill that has been identified at varying depths
across the Site.
Grading activities will be conducted in accordance with a grading plan utilizing grading
equipment (i.e. backhoes, front end loaders, bull dozers, etc.) and the Site development
contractor will implement best management practices in accordance with a sediment and
erosion control plan (i.e. implementation of silt fencing, berming, and covering stockpiled soil
with plastic) to manage soil on‐Site during Site redevelopment activities and to prevent
redistribution of soils onto adjacent properties. Grading and redevelopment activities will be
conducted in general accordance with applicable local, state, and federal regulations.
6) Estimated volume of excavated soil (cubic yards) anticipated to be impacted by contaminants:
Soil samples collected from in‐situ soil characterization sections EX‐18 and EX‐23 contained low
levels of benzo(a)pyrene at concentrations exceeding the Residential PSRGs. These sections
comprise a total of approximately 850 cubic yards of soil which are generally composed of urban
fill unsuitable for construction purposes and are therefore planned for excavation.
TPH as diesel range organics at a concentration above the DEQ UST Action Level are estimated to
be in shallow soil (less than 2 ft bgs) in an approximate 650 sq ft area in the northeastern portion
of the Site (Figure 3C). However, this area is proposed for fill during redevelopment activities
and no cut is this area is currently planned.
7) Estimated volume of contaminated soil expected to be disposed of offsite, if applicable:
Shallow soil unsuitable for construction purposes generated during grading activities in the areas
of EX‐18 and EX‐23 (total of approximately 850 cubic yards) will be exported off‐Site to a suitable
location with DEQ prior approval.
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).
1) HAZARDOUS WASTE DETERMINATION:
a) Does the soil contain a LISTED WASTE as defined in the North Carolina Hazardous
Waste Section under 40 CFR Part 261.31‐261.35?....................................... ☐Yes ☒No
9
EMP Version 2, June 2018
☐ If yes, explain why below, including the level of knowledge regarding processes
generating the waste (include pertinent analytical results as needed).
Click or tap here to enter text.
☐ If yes, do the soils exceed the “Contained‐Out” levels in Attachment 1 of the
North Carolina Contained‐In Policy?................................................. ☐ Yes ☐ No
b) NOTE: IF SOIL MEETS THE DEFINITION OF A LISTED HAZARDOUS WASTE AND EXCEEDS
THE CONTAINED‐OUT LEVELS IN ATTACHMENT 1 TO THE NORTH CAROLINA
CONTAINED‐IN POLICY THE SOIL MAY NOT BE RE‐USED ON SITE AND MUST BE
DISPOSED OF IN ACCORDANCE WITH DEQ HAZARDOUS WASTE SECTION RULES AND
REGULATIONS.
c) Does the soil contain a CHARACTERISTIC WASTE?.................................... ☐ Yes ☒ No
☐ If yes, mark reason(s) why below (and include pertinent analytical results).
☐ Ignitability Click or tap here to enter text.
☐ Corrosivity Click or tap here to enter text.
☐ Reactivity Click or tap here to enter text.
☐ Toxicity Click or tap here to enter text.
☐ TCLP results Click or tap here to enter text.
☐ Rule of 20 results (20 times total analytical results for an individual
hazardous constituent on TCLP list cannot, by test method, exceed regulatory
TCLP standard)
Click or tap here to enter text.
☒ If no, explain rationale:
Laboratory analysis of soil samples collected during previous assessment
activities did not identify compound concentrations at characteristically
hazardous levels or levels which exceed TCLP criteria using the Rule of 20. If soils
are disturbed during grading which are suspected to contain concentrations
above hazardous waste levels [based on visual observation or field screening
with a properly calibrated photoionization detector (PID)], the soil will be
sampled and managed in accordance with the procedures described below.
d) NOTE: IF SOIL MEETS THE DEFINITION OF A CHARACTERISTIC HAZARDOUS WASTE, THE
SOIL MAY NOT BE RE‐USED ON SITE AND MUST BE DISPOSED OF IN ACCORDANCE
WITH DEQ HAZARDOUS WASTE SECTION RULES AND REGULATIONS.
2) Screening criteria by which soil disposition decisions will be made (e.g., left in place, capped in
place with low permeability barrier, removed to onsite location and capped, removed offsite):
☒ Preliminary Health‐Based Residential SRGs

EMP Version 2, June 2018
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. Evidence of potential significantly
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:
In the unlikely event unknown 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 soil sample (no less than 3 aliquot soil samples at a sample ratio of 1 soil
sample per every approximately 1,000 cubic yards of 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. Impacted soil will be managed in the manner
described below based upon the laboratory analyses:
i. If no organic compounds are detected in a sample (other than which are
12
EMP Version 2, June 2018
attributable to sampling or laboratory artifacts) and metals are below the Protection of
Groundwater or Residential PSRG (whichever is lower for the detected compounds) and
are consistent with 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 written approval 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 IHSB
Residential 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 conditions.
iii. If detectable levels of compounds are found which exceed the DEQ IHSB
Residential 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 written approval, may be used
on‐Site as fill below an impervious surface, or at least 2 ft of verified compacted clean soil.
If the impacted soil with concentrations above Residential PSRGs is moved to an on‐Site
location, its location and depth will be documented, and its location will be provided to
DEQ.
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 redevelopment 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.
*Please note that should the PD elect to transport export soil to a permitted facility or to
a DEQ Brownfields pre‐approved receiving facility, soil will be direct loaded onto trucks
for transport off‐Site.
If soil samples are collected for analysis, please check the applicable chemical analytes:

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 future Site development (i.e., after grading
and utility construction), an environmental engineer will be contracted to assess the Site
for areas that will not be covered upon completion of the redevelopment with a minimum
of 2 ft of documented clean fill soil, building foundations, sidewalks, asphalt or concrete
parking areas and driveways, or other similar impervious areas (e.g., pavers). If such areas
exist, a Work Plan will be prepared for final grade soil sampling for DEQ Brownfields review
and approval.

EMP Version 2, June 2018
Based on the current Site redevelopment plan, one final grade soil sample will be collected
for laboratory analysis for each approximately 100 ft of linear landscape area or every
approximately 1,000 sq ft of open area. If no such areas exist, documentation will be
provided to the DEQ Brownfields project manager. Final grade soil samples will be consist
of several aliquot soil samples collected from within each evaluation area which will be
combined and homogenized to form one composite soil sample representative of that
evaluation area and submitted for analysis of SVOCs and RCRA metals. In addition, one
grab soil sample will be collected for each evaluation area and submitted for laboratory
analysis of VOCs.

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:
Based on the grading plan, grading activities at the Site will result in a net export. Therefore, the
need for a borrow source and fill material is not anticipated at this time. If necessary, upon
determination of a potential 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 at the Brownfields property.
The PD plans to import limited amounts of organic rich topsoil from a commercial landscape
15
EMP Version 2, June 2018
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.
6) Please check the applicable chemical analytes for fill soil samples. (Check all that apply):
☒ Volatile organic compounds (VOCs) by EPA Method 8260
☒ Semi‐volatile organic compounds (SVOCs) by EPA Method 8270
☒ Metals RCRA List (8) (arsenic, barium, cadmium, chromium, mercury, lead,
selenium and silver): Specify Analytical Method Number(s):
EPA Methods 6020/7471

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 import soil becomes necessary during redevelopment of the Site, 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 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.
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 analytical suite 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 the laboratory analytical suite indicated above at a general rate of approximately
one per 500 cubic yards.
16
EMP Version 2, June 2018
Fill soil will be considered suitable for use at the Site if it does not contain compound
concentrations above DEQ IHSB Residential PSRGs, DWM Risk Calculator risk thresholds, 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.
As noted above, grading for the proposed redevelopment at the Site will generate approximately
8,000 cubic yards of soil that will likely need to be transported off‐Site to achieve proposed final
grade elevations. Grading plans for the redevelopment generally include cut in western portions
of the property and fill in eastern portions of the property. However, results of geotechnical
assessment activities identified undocumented urban fill unsuitable for construction purposes at
varying depths in several areas (including fill areas in the eastern portion of the Site) that will
likely need to be exported from the Site. The anticipated export soil volume (8,000 cubic yards)
includes approximately 5,600 cubic yards of geotechnically unsuitable undocumented urban fill.
Cut depths on the western portion of the Site will extend to depths up to approximately 8.5 ft.
Results of recently completed in situ soil characterization assessment activities indicate that
composite soil samples collected from in‐situ soil characterization sections EX‐18 (0 to 3 ft below
grade) and EX‐23 (0 to 2 ft below grade) contained concentrations of benzo(a)pyrene above the
Residential PSRG. Soil in remaining areas of proposed export at the Site do not contain
compounds at concentrations above the PSRGs or naturally occurring levels in the case of metals.
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
17
EMP Version 2, June 2018
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).
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 or non‐permitted
disposal facility.
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:
Results of vapor intrusion assessment activities and recently completed supplemental vapor
intrusion assessment activities indicate that potential vapor intrusion concerns are limited to the
western portion of the Site. A vapor intrusion mitigation plan is proposed for buildings that will
be constructed in the western portion of the Site. Proposed utility trenches will be beneath the
vapor intrusion mitigation system and no additional barrier will be needed to further minimize
vapor transport through the utility trench.
Other comments regarding managing impacted soil in utility trenches:
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
18
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 in 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.
Should impacted soil be discovered during utility trenching activities, appropriate safety screening will
be performed to protect workers during utility installation activities. Safety screening activities
include monitoring the worker breathing zone with a calibrated photoionization detector or similar
instrument at all times when in utility trenches. If safety screening results indicate further action is
warranted, the work zone will be evacuated until appropriate engineering controls (such as use of
industrial fans) are implemented.
PART 2. GROUNDWATER – Please fill out the information below.
1) What is the depth to groundwater at the Brownfields Property?

EMP Version 2, June 2018
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)

☐ PCBs: Specify Analytical Method Number(s):
Click or tap here to enter text.
☒ Other Constituents & Analytical Method(s) (i.e. Hexavalent Chromium, Herbicides, etc.)
Please note, if field observations indicate the need for additional analyses, they should
be conducted, even if not listed here.
Hexavalent chromium 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 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 redevelopment activities, the
24
EMP Version 2, June 2018
environmental actions noted below will be used to assist in appropriate management of sub‐surface
environmental conditions and determination of the most suitable final disposition of potentially
impacted Site media.
Underground Storage Tanks:
In the event that an unknown 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. DEQ Brownfields will be notified within 48‐hours of discovery of the UST.
If an unknown UST is encountered, the UST will be removed, if possible, and transported off‐Site for
disposal at a suitable facility. Prior to removing the UST from the ground, residual fluids, if any, will
be sampled for VOCs, SVOCs, and RCRA metals as needed for disposal purposes. If a UST is
encountered that cannot be removed, it may be abandoned in‐place with prior DEQ approval and
construction will proceed. Where appropriate, the bottom of the UST may be penetrated before
abandonment to prevent fluid accumulation. Impacted soil in the vicinity of the UST will be
managed in accordance with the Managing On‐Site Soil section outlined in this EMP.
Sub‐Grade Feature/Pit:
If a sub‐grade feature or pit is encountered, it will be removed and transported off‐Site for disposal
at a suitable facility. If it cannot be removed, it will be filled with soil or suitable fill. Where
appropriate, the bottom of the sub‐grade feature or pit 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 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 project environmental engineer. The environmental
engineer will observe the suspect materials and collect samples for laboratory analysis, if
warranted. 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 RCRA metals (or other analyses as
appropriate based on the type of waste material). Information will be provided to DEQ Brownfields
regarding the permitted facility used for disposal of the waste or significantly impacted soil. Areas of
suspected contaminated soil that remain at the Site after excavation is complete above the DEQ
IHSB Residential PSRGs will be managed pursuant to this plan.
Re‐Use of Impacted Soils On‐Site:
25
EMP Version 2, June 2018
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:
