EMP Version 2, January 2021
NORTH CAROLINA BROWNFIELDS PROGRAM
ENVIRONMENTAL MANAGEMENT PLAN

This form is to be used to prepare an Environmental Management Plan (EMP) for projects in
the North Carolina Brownfields Program at the direction of a Brownfields project manager.

The EMP is a typical requirement of a Brownfields Agreement (BFA). Its purpose is to clarify
actions to be taken during the demolition and construction at Brownfields properties in an
effort to avoid delays in the event of the discovery of new contamination sources or other
environmental conditions. The EMP provides a means to document redevelopment plans and
environmental data for each applicable environmental medium to inform regulatory-compliant
decision-making at the site. As much detail as possible should be included in the EMP,
including contingency planning for unknowns. Consult your project manager if you have
questions.

Prospective Developers and/or their consultants must complete and submit this form and all
pertinent attachments, see checklist below, to their Brownfields project manager prior to any
earthmoving or other development-related activities that have the potential to disturb soil at
the Brownfields Property, including demolition. For the resultant EMP to be valid for use, it
must be completed, reviewed by the program, signed by all parties working on the project,
and approved by the Brownfields project manager. Failure to comply with the requirements of
the EMP could jeopardize project eligibility, or in the event of a completed agreement, be
cause for a reopener.

The EMP is valid only for the scope of work described herein and must be updated to be
applicable for new phases of redevelopment or after significant changes in applicable
regulatory guidance.

Voluntary Metrics Tab
The NC Brownfields Program updates estimated capital investment (from the Brownfields
Property Application) and estimated jobs created (from the Brownfields Agreement) whenever
possible. As a voluntary measure, you may opt to complete the below information for capital
investment and jobs created as estimated by your final redevelopment plans for the Brownfields

The redevelopment activities covered under this EMP include shallow soil excavations within and
north of the P Building (formerly known as the Training Building) for the installation of concrete
foundations for additional equipment to be used by the current tenant Eastern Fence. Eastern
Fence manufactures PVC fencing at the P Building using PVC powder and injection molding
equipment. The construction activities include installation of concrete foundations for the
following:
x Two silos north of the P Building. These silos will contain a mixture of PVC powder and
calcium carbonate.
x Three silos northeast of the P Building. The westernmost of these silos will contain
calcium carbonate, and the other two will contain PVC powder.
x Liquid stabilizer tank containment north of the P Building. A Safety Data Sheet for the
liquid stabilizer is provided in Appendix D. The liquid stabilizer tank will be in secondary
containment. The containment will have a central drain that will remain closed until
accumulated rainwater is inspected and verified to be non-impacted before draining.
x Mixer/cooler within the P Building. This is a high intensity mixer and a vertical drum
cooler with a water jacket.
x Approximate 100 ft long trench to a new power pole will also be performed to install a
new underground power line to the P Building.

The approximate locations and sizes and depths of the excavations are indicated in Figures 3 and
4, respectively. Construction drawings are provided in Appendix A. Excavation depths are not
expected to exceed 2.5 ft. In addition, two blower pads will be installed northeast and east of

7

Management of fugitive dust from site
܈ Yes, describe the method will include:
Contaminated soil is not expected to be encountered or disturbed as part of the
excavations. However, the construction contractor will take into account conditions such as
wind speed, wind direction, and moisture content of soil during soil disturbance and
stockpiling activities to minimize dust generation. 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).

܆ 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 contractor will observe soils for evidence of
potential significantly impacted soil. Evidence of potential 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 consultant 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 consultant will
contact the DEQ Brownfields project manager within 48-hours to advise that person of the
condition.

Click or tap here to enter text.

12
EMP Version 2, January 2021
Collection of additional soil samples is not anticipated based on results of previous Site
assessment activities and previous use of the P Building for training. If previously
unknown significant soil impact is encountered during soil disturbance, excavation will
proceed only as far as needed to allow construction to continue and/or only as far as
needed to allow alternate corrective measures described below.

Suspect impacted soil excavated during will 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
200 cubic yards of soil will be collected for the analyses selected below (i.e., total VOCs,
SVOCs, and RCRA metals plus hexavalent chromium). If the soil sample laboratory
analytical results 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
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 with acceptable cumulative risk
calculator results, 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
Industrial PSRGs (other than which are attributable to sampling or laboratory artifacts or
which are consistent with Site-specific background levels for metals), the TCLP
concentrations are below hazardous waste criteria, and cumulative risk calculator results
are acceptable, 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
Industrial 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 documented compacted
clean soil. If the impacted soil with concentrations above Industrial PSRGs is moved to
an on-Site location, its location and depth will be documented using GPS, and its location
will be provided to DEQ
iv. Impacted soil may be transported to a Brownfields approved 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 or
acceptance to dispose of soil from the Site will be provided to the DEQ Brownfields
project manager.
v. 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.

13
EMP Version 2, January 2021
*Please note that should export soil be transported off-Site to a permitted facility or to a
another 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:
܈ 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

Hexavalent Chromium by EPA Method 7199

܈ Check to confirm that stockpiling of known or suspected impacted soils will be conducted
in accordance with Figure 1 of this EMP. Stockpile methodology should provide erosion
control, prohibiting contact between surface water/precipitation and contaminated soil,
and preventing contaminated runoff. Explain any variances or provide additional details as
needed:

܆ Final grade sampling of exposed native soil (i.e., soil that will not be under buildings or
permanent hardscape). Select chemical analyses for final grade samples with check boxes
below (Check all that apply):

Click or tap here to enter text.

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, indicate if a work
plan for final grade sampling may be submitted under separate cover.

܈ If final grade sampling was NOT selected, please explain rationale:
No final grade soil sampling is proposed because there are no known soil impacts in the
area of the excavations and there will be minimal disturbance of soil outside the
excavation areas. If significantly impacted soil is identified during the excavations and the
impacted soil removed from the excavations is found to contain compounds above
Industrial PSRGs, then the need for final grade soil sampling will be discussed with the
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?

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.
In the unlikely event that import fill soil is needed, it will be taken from a location on-Site south
of the parking lot where no prior industrial activities have occurred. If off-Site fill soil is needed
for some reason, then the location where the fill soil will be obtained while be submitted to the
DEQ Project Manager for prior approval. If the import fill soil is not from a DEQ Brownfields pre-
approved soil import facility (i.e., pre-characterized quarry), then a plan for characterization of
the soil will also be submitted for DEQ approval.

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

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

16
EMP Version 2, January 2021
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.
No off-Site export of soil is anticipated based upon the large size of the Site where soil can be
placed (unless impacted soil is identified in the excavations and is disposed off-Site in accordance
with Part 1.A. Section 4.)

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
property, and that a record of the acceptance of such soil from the property owner of
the receiving site is provided to Brownfields. Please provide additional details below.
܆ Use as Beneficial Fill off-site at a non-Brownfields Property - Please provide
documentation of approval from the property owner for receipt of fill material. This will
also require approval by the DEQ Solid Waste Section. Additional information is
provided in IR 15. Please provide additional details below.

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

Part 1.D. MANAGEMENT OF UTILITY TRENCHES

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

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

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

17
EMP Version 2, January 2021
Vapor Mitigation Plan. Note that if vapor mitigation is planned for site buildings, utility
corridors will need to be evaluated as part of mitigation designs:
Click or tap here to enter text.

܈܈ If no, include rationale here:
Results of previous sub-slab soil vapor assessment activities completed below the P Building (as
well as elsewhere at the Site) did not indicate the presence of compounds above DEQ Non-
Residential Soil Gas Screening Levels (SGSLs). Therefore, no soil vapor impacts are expected in
utility trenches or other excavations.

܆ Unknown, details to be provided in the Vapor Mitigation Plan for site buildings

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
noted during utility work, the contractor will contact the project environmental consultant to observe
the suspect condition. If the project environmental consultant confirms that the material may be
impacted, then the procedures outlined in Part 1.A. Section 4 above will be implemented. In addition,
the environmental consultant will contact the DEQ Brownfields project manager within 48-hours to
advise that person of the condition.

Should impacted soil be discovered during utility trenching activities, appropriate safety screening will
be performed by the contractor to protect workers during utility installation activities. If safety
screening results indicate further action is warranted, the environmental consultant will be contacted
and the work zone will be evacuated until appropriate engineering controls (such as use of industrial
fans) are implemented. The environmental consultant will notify the DEQ project manager within 48
hours if engineering controls are warranted.

PART 2. GROUNDWATER

1) What is the depth to groundwater at the Brownfields Property?
The depth to groundwater in the area of the P Building is approximately 30 ft below ground
surface.

2) Is groundwater known to be contaminated by ܈onsite ܆offsite ܆both or ܆unknown
sources? Describe source(s):
The primary sources of groundwater impacts are the former DowTherm heaters located east of
the main Site building, the Glycol Recovery Unit Bottom (GRUB) landfill in the eastern portion of
the site, the Chromium Reduction Unit basins in the area of the current wastewater treatment
plant, and the wastewater polishing ponds. These areas are identified in Figure 2.

3) What is the direction of groundwater flow at the Brownfields Property?

18
EMP Version 2, January 2021
Groundwater flow is to the east toward Second Creek (see Figure 2).

4) Will groundwater likely be encountered during planned redevelopment activities?
܆܆Yes ܈No
If yes, describe these activities:
.

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).
Appropriate worker safety measures will be undertaken in the highly unlikely event that
groundwater gathers in an open excavation within an area determined to be impacted during
construction activities. The accumulated water will be allowed to evaporate/infiltrate to the
extent time for dissipation does not disrupt the construction schedule. Should the time needed
for natural dissipation of accumulated water be deemed inadequate, an environmental
professional will be contacted and the water will be tested and disposed off-Site or discharged
to the on-site wastewater treatment plant.

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.

No monitoring wells are located in the area of the proposed excavations. The closest monitoring well
is located approximately 180 ft northwest of the closest excavation area (well DT-3SS; see plat in
Appendix B).

2) Attach a map showing the location of surface water at the Brownfields Property.
3) Is surface water at the property known to be contaminated? ܈ Yes ܆ No
4) Will workers or the public be in contact with surface water during planned redevelopment
activities? ܆ Yes ܈ No
5) In the event that contaminated surface water is encountered during redevelopment
activities, or clean surface water enters open excavations, list activities for management of
such events (e.g., flooding, contaminated surface water run-off, stormwater impacts):
If surface water run-off gathers in an open excavation within an area determined to contain
impacted soil, appropriate worker safety measures will be undertaken. The accumulated water
will be allowed to evaporate/infiltrate to the extent time for dissipation does not disrupt the
construction schedule. Should the time needed for natural dissipation of accumulated water be
deemed inadequate, the water will be tested and disposed off-Site or discharged to the on-Site
wastewater treatment plant. If surface water collects in an excavation with non-impacted soil,
the water will be discharged to the surface and allowed to evaporate or discharged to the on-Site
wastewater treatment plant.

PART 4. SEDIMENT

1) Are sediment sources present on the property? ܈ Yes ܆ No

2) If yes, is sediment at the property known to be contaminated: ܈ Yes ܆ No ܆ Unknown

3) Will workers or the public be in contact with sediment during planned redevelopment
activities? ܆ Yes ܈ No

4) Attach a map showing location of known contaminated sediment at the property.

5) In the event that contaminated sediment is encountered during redevelopment activities, list
activities for management of such events (stream bed disturbance):
Contaminated sediment is known to present in the wastewater polishing ponds. The closest pond
is located greater than 900 ft from the P Building.

܆ Yes ܈ No܆ Unknown

In the event that contaminated soil vapor is encountered during redevelopment activities
(trenches, manways, basements or other subsurface work,) list activities for management of
such contact:
If potential soil or vapor impacts are identified during excavation, appropriate vapor monitoring
will be performed by the contractor. If vapor monitoring results indicate potential vapor phase
contamination at levels of concern for worker protection, an environmental professional will be
contacted and the work zone will be evacuated until appropriate engineering controls (such as
use of industrial fans) are implemented.

PART 6. SUB-SLAB SOIL VAPOR
1) Do concentrations of volatile organic compounds at the Brownfields property exceed the
following vapor intrusion screening levels (current version) in sub-slab soil vapor:
IHSB Residential Screening Levels:
Soil Vapor:………..܆ Yes ܆ No ܈ Unknown

showing the location of these exceedances.
3) At what depth(s) is sub-slab soil vapor known to be contaminated? ܈0-6 inches ܆Other, please
describe:
H&H collected sub-slab soil gas samples for laboratory analysis in June 2020 from below the P
Building as well as other Site buildings. The sample locations and a summary of the sub-slab soil
vapor analytical data is provided in Appendix C. As shown in Appendix C, no VOCs were detected
at concentrations above the DEQ Non-Residential SGSLs below the P Building or other Site
See below regarding sub-slab soil vapor.

21
EMP Version 2, January 2021
buildings where samples were collected.
.

4) Will workers encounter contaminated sub-slab soil vapor during planned redevelopment
activities? ܆܆ Yes ܈ No ܆ Unknown

܆ If no, include rationale here:
Based upon previous sub-slab soil vapor analytical data at the P Building, it is unlikely that
contaminated soil vapor will be encountered during the shallow soil excavations.
5) In the event that contaminated soil vapor is encountered during redevelopment activities, list
activities for management of such contact
As noted above, if potential soil or vapor impacts are identified during excavation, appropriate
vapor monitoring will be performed by the contractor. If vapor monitoring results indicate
potential vapor phase contamination at levels of concern for worker protection, an
environmental professional will be contacted and the work zone will be evacuated until
appropriate engineering controls (such as use of industrial fans) are implemented.

PART 7. INDOOR AIR

1) Are indoor air data available for the Brownfields Property? ܆ Yes ܈ No ܆ Unknown
2) Attach a map showing the location(s) where indoor air contaminants exceed site screening levels.
3) If the structures where indoor air has been documented to exceed risk-based screening levels will
not be demolished as part of redevelopment activities, will workers encounter contaminated
indoor air during planned redevelopment activities? ܆ Yes ܈ No ܆ Unknown

܈ If no, include rationale here:
Previous sampling of sub-slab soil vapor at the P Building did not indicate concentrations above
SGSLs. Therefore, it is unlikely that there are contaminants in indoor above risk-based screening
levels from soil or groundwater impacts at the Site.

4) In the event that contaminated indoor air is encountered during redevelopment activities, list
activities for management of such contact:

In the unlikely event there is evidence of potential indoor air issues (i.e., unusual odors) during the
interior soil excavation, appropriate indoor air monitoring will be performed by the contractor. If
indoor air monitoring results indicate potential indoor air contamination of concern for worker
protection, an environmental professional will be contacted and the work area will be evacuated until
appropriate engineering controls (such as use of industrial fans) are implemented and follow up
sampling is performed to confirm a safe working environment.

22
EMP Version 2, January 2021
VAPOR INTRUSION MITIGATION SYSTEM
Is a vapor intrusion mitigation system (VIMS) proposed for this Brownfields Property?
܆܆ Yes ܈ No ܆ Unknown

܈ If no or unknown, include rationale here as well as plans for pre-occupancy sampling, as
necessary:
Sub-slab sampling did not indicate that vapor mitigation is warranted at the Brownfields site for
existing buildings. No vapor mitigation is required for existing buildings per the draft Brownfields
agreement.

If yes, ܆ VIMS Plan Attached or ܆ VIMS Plan to be submitted separately
If submitted separately provide date:

VIMS Plan shall be signed and sealed by a NC Professional Engineer

If no, please provide a brief rationale as to why no vapor mitigation plan is warranted:
See above.

Note that approval of this EMP does not imply approval with any vapor intrusion mitigation land
use restrictions or requirements of the recorded or draft Brownfields Agreement and that
separate approval of mitigation measures will be required.

CONTINGENCY PLAN – encountering unknown tanks, drums, or other waste materials

In this section please provide actions that will be taken to identify or manage unknown
potential new sources of contamination. During redevelopment activities, it is not uncommon
that unknown tanks, drums, fuel lines, landfills, or other waste materials are encountered.
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 6020/7471

܈ 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. In the event that such conditions are encountered during construction activities, the
actions noted below will be taken. Sampling data for potentially impacted soil and the disposition
of impacted soil will be provided to DEQ when the data becomes available.

Underground Storage Tanks:
In the event a UST or impacts associated with a UST release are discovered at the Site during the
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 a UST is encountered, the UST will be removed, if possible and the UST will be transported off-Site
for disposal at a suitable facility. If the UST contains residual fluids, the fluids will be sampled for
VOCs, SVOCs, and RCRA metals (unless the fluids are a known product such as fuel oil), and
transported off-Site for disposal at a suitable facility based on the laboratory analytical results prior
to removing the UST from the ground. If a UST is encountered that cannot be removed or does not
require removal for geotechnical or construction purposes, it may be abandoned in-place with prior
DEQ approval and construction will proceed. Where appropriate, the bottom may be penetrated
after removal of residual fluids and 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 above in the EMP. DEQ UST Program protocol (or other protocol approved in advance by
the DEQ Brownfields Program) will be followed for UST abandonment procedures.

Sub-Grade Feature/Pit:
If a sub-grade feature or pit is encountered and does not require removal for geotechnical or
construction purposes, it will be filled with soil or suitable fill and construction will proceed. Where
appropriate, the bottom may be penetrated before back filling to prevent fluid accumulation. If the
pit has waste in it, the waste will 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 Part 1.A. Section 4 outlined above in the

24
EMP Version 2, January 2021
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 – Note that if buried waste, non-native fill, or any obviously filled materials
is encountered, the DEQ Brownfields Program must be notified to determine if investigation of
landfill gases is required:
If 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 RCRA metals plus hexavalent chromium. Areas of suspected contaminated soil
that remain at the Site after excavation is complete above the DEQ IHSB Industrial PSRGs will be
managed pursuant to this plan.

Re-Use of Impacted Soils On-Site:
Please refer to description outlined in the Part 1.A. Section 4 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:
