PART 1. SOIL — Please fill out the information below, using detailed site plans, if available, or estimate
using known areas of contaminated soil and a conceptual redevelopment plan. Provide a figure
overlaying new construction onto figure showing contaminated soil and groundwater locations.
1) Known or suspected contaminants in soil (list specific compounds):
Historical use of the Brownfields property included truck and bus repairs (1920s-1950s), electrical
switchboard and switch manufacturing (1920s-mid 1960s), and janitorial chemical manufacturing
uses (mid-1970s to current).
Laboratory analytical results of soil samples collected during March 2018 Brownfields assessment
activities, identified arsenic (up to 17 mg/kg) and lead (up to 9,300 mg/kg) at concentrations
exceeding the North Carolina Department of Environmental Quality (DEQ) Inactive Hazardous Sites
Branch (IHSB) Residential and Industrial/Commercial Preliminary Soil Remediation Goals (PSRGs).
Benzo(a)anthracene (up to 1.3 mg/kg), benzo(a)pyrene (up to 1.3 mg/kg), benzo(b)fluoranthene (up
to 1.8 mg/kg), dibenz(a,h)anthracene (up to 0.30 mg/kg), and hexavalent chromium (up to 3.2 mg/kg)
were detected at concentrations exceeding the Residential PSRGs. No other compounds have been
identified at concentrations exceeding Residential or Industrial/Commercial PSRGs in Site soil.
Soil sample laboratory analytical results are summarized in Table 1 and depicted on Figure 4.
2) Depth of known or suspected contaminants (feet): Compounds at concentrations above the
Industrial/Commercial PSRGs were identified in shallow soil (0-1 ft bgs) in the sample collected from
soil boring SB-6 advanced in the vicinity of the former electrical switchboard manufacturing area
(currently known as the "light well area"). Additionally, compounds detected at concentrations
exceeding the Residential PSRGs were identified in the SB-8 soil sample at a depth of 4.5 -5.5 ft bgs
collected adjacent to the former above -ground storage tank (AST) secondary containment system.
3) Area of soil disturbed by redevelopment (square feet):
Approximately 12,000 sq ft will be disturbed in portions of the Brownfields property planned for
parking, installation of subgrade utilities, installation of the stormwater conveyance system,
installation/repair footings, and repair of building concrete slab floors. Grading activities will be
limited to leveling for new paved parking areas. 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 (i.e.
implementation of silt fencing, berming, and covering stockpiled soil with plastic) to manage soil
during Site redevelopment activities to prevent redistribution of soils onto adjacent properties. The
proposed Grading Plan is included in Appendix D.
4) Depths of soil to be excavated (feet): Soil excavation for installation stormwater conveyance
piping, subgrade utilities, and the concrete footings may extend up to approximately 5 ft bgs.
4
EMP Form ver.1, October 23, 2014
5) Estimated volume of soil (cubic yards) to be excavated (attach grading plan): Up to
approximately 1,600 cubic yards of soil are planned to be disturbed and re -used on -Site during
grading activities.
6) Estimated volume of excavated soil (cubic yards) anticipated to be impacted by contaminants: Up
to approximately 100 cubic yards of potentially impacted soil may be excavated or disturbed during
redevelopment of the Brownfields property. If soil is disturbed during grading/Site work activities in
the vicinity of soil sample S13-6 (light well area), or if unexpected potentially impacted soil is
encountered during grading activities on the Brownfields property, soil will be segregated and
stockpiled on and covered with a minimum of 10-mil plastic to allow for construction activities to
continue. An environmental professional will collect a composite soil sample from the stockpile for
laboratory analysis (as described in the Managing Onsite Soil section below) to determine the
appropriate final disposition of the potentially impacted material.
7) Estimated volume of contaminated soil expected to be disposed of offsite, if applicable:
None anticipated
IMPORTED FILL SOIL
1) Will fill soil be imported to the site? ❑ Yes ❑ No ❑x Unknown
2) If yes, what is the estimated volume of fill soil to be imported? Import soil for use as beneficial fill
is not anticipated at this time. Should import soil be needed during redevelopment of the
Brownfields property, the PD will contact DEQ Brownfields and the procedures outlined in item #4
below will be implemented.
3) If yes, what is the depth of fill soil to be used at the property? Not applicable
If a range of depths, please list the range.
4) PRIOR TO ITS PLACEMENTAT THE BROWNFIELDS PROPERTY, provide plan to analyze fill soil to
demonstrate that it meets acceptable standards and can be considered clean for use at the
Brownfields property (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 (speciated), mercury, lead,
selenium and silver)
❑ Metals —Hazardous Substance List -14 (antimony, arsenic, beryllium, cadmium, chromium
(speciated according to IHSB protocol), copper, lead, manganese, mercury, nickel, selenium, silver,
thallium, and zinc)
❑ Metals — EPA Priority Pollutant List — 13 (arsenic, beryllium, cadmium, chromium (speciated
according to IHSB protocol), copper, mercury, nickel, lead, antimony, selenium, silver, thallium, and
zinc)
❑ Other Constituents & Analytical Method: rlirk harp to antpr tax
❑ Known borrow material (DESCRIBE SOURCE AND ATTACH SAMPLING PROFILE):
The PD does not plan to collect samples of landscaping materials obtained from a commercial vendor
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.
For import structural fill needed for future redevelopment of the Site, the PD will follow the procedures
outlined below.
EMP Form ver.1, October 23, 2014
If the PD plans to import fill material from the 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 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 NCDEQ
PSRGs for Industrial/Commercial Use or typical metals concentrations which are consistent with
background levels identified at the Site.
Fill soil may also be obtained from another Brownfields property with DEQ Brownfields prior written
approval.
MANAGING ONSITE SOIL
1) If soil in known or suspected areas of contamination 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).
2) HAZARDOUS WASTE DETERMINATION — 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
If yes, explain why below, including the level of knowledge regarding processes generating the
waste (include pertinent analytical results as needed). Click 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
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 DENR
HAZARDOUS WASTE SECTION RULES AND REGULATIONS.
3) HAZARDOUS WASTE DETERMINATION — Does the soil contain a CHARACTERISTIC WASTE?:
® Yes ❑ No
If yes, mark reason(s) why below (and include pertinent analytical results).
❑ Ignitability
❑ Corrosivity
❑ Reactivity
❑ Toxicity
® TCLP results — Elevated lead concentrations (up to 9,300 mg/kg) were detected in
soil sample SB-6 and the S13-6 duplicate soil sample DUP-1 collected at a depth of 0-1 ft bgs in the light
6
EMP Form ver.1, October 23, 2014
well area. Based on laboratory analytical results of the SB-6 and DUP-1 soil samples, the samples were
submitted for laboratory analysis for lead by Toxicity Characteristic Leaching Procedure (TCLP). TCLP
laboratory analytical results indicate that lead was detected at concentrations (up to 29 mg/L) exceeding
the Regulatory Level for lead of 5 mg/L in the soil samples collected from the light well area. Laboratory
analytical results of the TCLP analysis are included in Appendix E.
❑ 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)
If no, explain rationale:
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 DENR HAZARDOUS WASTE
SECTION RULES AND REGULATIONS.
4) 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
® Preliminary Health -Based Industrial/Commercial SRGs 2/1/2018
❑ Site -specific risk -based cleanup level, or acceptable concentrations determined via
calculated cumulative risk. Enter details of methods used for determination/explanation:
5) Check the following action(s) to be taken during excavation and management of said soils:
® Manage fugitive dust from site:
® Yes ❑ No
If yes, describe method; If no, explain rationale: Limited areas of potentially impacted soil will
be encountered or disturbed during future Site redevelopment activities based upon previous soil
sampling analytical data. The grading contractor will take into account conditions such as wind speed,
wind direction, and moisture content of soil during soil grading and stockpiling activities to minimize
dust generation.
In the event that contaminated soil is encountered during Site redevelopment that requires excavation,
particular attention will be paid by contractors to implement dust control measures as needed based on
Site and atmospheric conditions (i.e. by controlled water application). Impacted soil will be managed as
described below.
® Field Screening:
® Yes ❑ No
If yes, describe method; If no, explain rationale: During soil disturbance at the Site, the
workers or contractors will observe soils for evidence of potential significantly impacted soil. 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.
7
EMP Form ver.1, October 23, 2014
® Soil Sample Collection:
® Yes ❑ No
If yes, describe method (e.g., in -situ grab, composite, stockpile, etc.); If no, explain rationale:
If significant soil impact is encountered during grading, installation of concrete footings and slabs,
and/or installation or removal of utilities, excavation will proceed only as far as needed to allow grading
and/or construction to continue and/or only as far as needed to allow alternate corrective measures
described below. Soils disturbed from the immediate vicinity of soil boring SB-6, as well as suspect
significantly impacted soil excavated during redevelopment activities 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 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 TCLP for those compounds that could exceed the
toxicity characteristic hazardous waste criteria. Impacted soil will be handled in the manner described
below based upon the laboratory analyses:
i. If no organic compounds are detected in a sample (other than which are attributable to
sampling or laboratory artifacts) and metals are below the DEQ 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 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.
® Stockpile impacted soil in accordance with NCDENR IHSB protocol in the current version of
the "Guidelines for Assessment and Cleanup", and providing erosion control, prohibiting
contact between surface water/precipitation and contaminated soil, and preventing
contaminated runoff. Explain any variances:

❑ Metals — EPA Priority Pollutant List — 13 (arsenic, beryllium, cadmium, chromium
(speciated according to IHSB protocol), copper, mercury, nickel, lead, antimony, selenium, silver,
thallium, and zinc)
❑ Other Constituent(s) & Analytical Method(s): If suspected contaminated soil is
identified during Site redevelopment activities, soil will be sampled and analyzed for VOCs, SVOCs, and
RCRA metals plus hexavalent chromium. VOC and SVOC concentrations will be compared to
Industrial/Commercial Use PSRGs. Metal concentrations will be compared to Industrial/Commercial Use
PSRGs, Site -specific background levels.
® Proposed Measures to Obtain Pre -Approval for Reuse of Impacted Soil within the
Brownfields Property Boundary
® Provide documentation of analytical report(s) to Brownfields Project Manager
® Provide documentation of final location, thickness and depth of relocated soil on
site map to Brownfields Project Manager once known
® Use geotextile to mark depth of fill material (provide description of material)
® Manage soil under impervious cap ® or clean fill
Describe cap orfill: If contaminated soil is encountered, it will be placed under impervious
materials or at least 2 ft of clean fill. Potential impervious caps include future building foundations
and paved areas. See attached development plan in Appendix B. (provide location diagram)
® Confer with NC BF Project Manager if Brownfield Plat must be revised (or re-
recorded if actions are Post -Recordation).

EMP Form ver.1, October 23, 2014
❑ PCBs
❑ Other Constituents & Analytical Method: 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 building foundations,
sidewalks, or asphalt or concrete parking areas and driveways, or other similar impervious areas. Based
on observations made by the environmental professional, a plan will be prepared for final grade sampling
and submitted to DEQ Brownfields for review and approval.
OFFSITE TRANSPORT & DISPOSITION OF EXCAVATED SOIL
NOTE: Unless soil will be transported offsite for disposal in a permitted facility under applicable
regulations, no contaminated or potentially contaminated soil may leave the site without approval
from the brownfields program. Failure to obtain approval may violate a brownfields agreement,
endangering liability protections and making said action subject to enforcement. Justifications
provided below must be approved by the Program in writing prior to completing transport activities.
® Transport and dispose of impacted soil offsite (documentation of final disposition must be sent to
Brownfields Project Manager)
® Landfill - analytical program determined by landfill
® Landfarm or other treatment facility Click here to enter text.
❑ Use as Beneficial Fill Offsite - provide justification: slick hero t- ontor to-
® Use as Beneficial Fill at another Suitable Brownfields Site - (Note: a determination that a
site is a "Suitable Brownfields" site will require, at a minimum, that similar concentrations of the same
or similar contaminants already exist at both sites, use of impacted soil as beneficial soil will not
increase the potential for risk to human health and the environment at that site, and that notarized
documentation of the acceptance of such soil from the property owner of the receiving site is
provided to Brownfields. Provide justification: As previously mentioned, cut/fill at the site is
expected to balance. However, in the unlikely event that soil needs to be exported off -site, a request
will be submitted to DEQ requesting approval prior to movement of soil off -site, unless the soil is
taken to a permitted facility.
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? Result: Yes ❑ No X
If no, include rationale here
If yes, provide specifications on barrier materials

PART 2. GROUNDWATER — Please fill out the information below and attach figure showing
distribution of groundwater contaminants at site
What is the depth to groundwater at the Brownfields Property? During groundwater assessment
activities conducted at the Site in March 2018, the potentiometric groundwater surface was measured
at depths ranging from approximately 13.3 ft bgs (TMW-3) in the northeastern portion of the Site to
approximately 16.5 ft bgs (TMW-1) in the northwestern portion of the Site.
Is groundwater known to be contaminated by ®onsite ® offsite ❑ both ❑ or unknown
sources? Describe source(s): Laboratory analytical results of groundwater samples collected during
March 2018 Brownfields assessment activities identified benzene (up to 7.9 µg/L), naphthalene (up to
6.6 µg/L), carbon tetrachloride (up to 4.8 J µg/L), and 1-methylnaphthalene (up to 2.6 J µg/L) at
concentrations exceeding the DEQ groundwater screening criteria established under 15A NCAC
02L.0202 in upgradient temporary groundwater monitoring wells TMW-4 and/or TMW-5. Carbon
tetrachloride in the TMW-4 groundwater sample also slightly exceeds the DEQ Division of Waste
Management (DWM) February 2018 Residential Vapor Intrusion Groundwater Screening Level (GWSL).
Vinyl chloride (0.85 J µg/L) and trichloroethylene(TCE) (11 µg/L) were detected at concentrations
exceeding the 2L Standards in the TMW-2 groundwater sample collected downgradient of the former
bus repair area and Wepak Corporation operations. The TCE concentration also exceeds the DEQ DWM
Non -Residential GWSL. However, DEQ Risk Calculator (February 2018) results indicate that cumulative
Carcinogenic Risk (2.4 X 10-6) and the cumulative Hazard Index (0.51) for compounds detected in the
TMW-2 groundwater sample are within the acceptable risk range for a Non -Residential use scenario.
What is the direction of groundwater flow at the Brownfields Property? Groundwater beneath the
Site is expected to mimic surface topography and flow approximately from south-southwest toward the
north-northeast.
Will groundwater likely be encountered during planned redevelopment activities? ❑ Yes ® No
If yes, describe these activities:
It is not anticipated that groundwater will be encountered during construction activities conducted in
the area of planned redevelopment.
Should groundwater reach the surface during redevelopment of the Brownfields property, 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.
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, 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.

Will workers or the public be in contact with surface water during planned redevelopment activities?
❑ Yes ® No
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 determined during construction to be impacted,
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.
=DIMENT — Please fill out the information below.
Is sediment at the property known to be contaminated: ❑ Yes ® No
Will workers or the public be in contact with sediment during planned redevelopment activities?
❑ Yes ® No

measured at 13.7 feet bgs. The calculated cumulative risks do not exceed acceptable risk levels for a
non-residential worker exposure scenario.
Will workers encounter contaminated soil vapor during planned redevelopment activities?
❑ Yes ❑ No ® Unknown
In the event contaminated soil vapor is encountered during redevelopment activities (trenches,
manways, basements or other subsurface work), list activities for management of such contact:
In the unlikely event potentially impacted soil vapors are encountered during future redevelopment
activities, the area will be evacuated and appropriate safety screening of the vapors will be
performed (ex. worker breathing zone will be monitored using a calibrated photoionization detector)
and the Brownfields project manager will be notified. If results indicate further action is warranted,
appropriate engineering controls (such as use of industrial fans) will be implemented. In addition,
the potential need for building vapor mitigation will also be considered at that time.
PART 6. SUB -SLAB SOIL VAPOR -please fill out the information below if existing buildings or
foundations will be retained in the redevelopment.
Are sub -slab soil vapor data available for the Brownfields Property? ❑ Yes ® No ❑ Unknown
If data indicate that sub -slab soil vapor concentrations exceed screening levels, attach a map showing
the location of these exceedances.
At what depth(s) is sub -slab soil vapor known to be contaminated? ❑ 0-6 inches ® Other, If other
describe: No sub -slab vapor samples have been collected at the Site. Therefore, the potential for
impacts in sub -slab vapor is unknown.
Will workers encounter contaminated sub -slab soil vapor during planned redevelopment activities?
❑ Yes ❑ No ® Unknown
In the event that contaminated soil vapor is encountered during redevelopment activities, list
activities for management of such contact: In the unlikely event potentially impacted soil vapors are
encountered during future redevelopment activities, worker breathing zone will be monitored using
a calibrated photoionization detector and the Brownfields project manager will be notified. If results
indicate further action is warranted, appropriate engineering controls (such as use of industrial fans)
will be implemented. In addition, the potential need for building vapor mitigation will also be
considered at that time.

PART 7. INDOOR AIR — Please fill out the information below.
Are indoor air data available for the Brownfields Property? ❑ Yes ® No ❑ Unknown
If yes, attach a map showing the location where indoor air contaminants exceed site screening levels.
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
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 future redevelopment activities, the area will be evacuated and
appropriate safety screening of the indoor air will be performed, and the Brownfields project
manager will be notified. If results indicate further action is warranted, appropriate engineering
controls (such as use of industrial fans) will be implemented. If warranted, safety screening
procedures will include periodically screening indoor air for volatile organic vapors with a calibrated
photoionization detector when workers present in the Site buildings identify potential indoor air
issues. In addition, the potential need for building vapor mitigation will also be considered at that
time.
11 PART 8 — Vapor Mitigation System — Please fill out the information below.
Is a vapor intrusion mitigation system proposed for this Brownfields Property?
❑ Yes ❑ No ® Unknown
If yes, provide the date the plan was submitted to the Brownfields Program.

Notes:
1) North Carolina Department of Environmental Quality (DEQ) Inactive Hazardous Sites Branch (IHSB) Preliminary Soil Remediation Goals (PSRGs) (February 2018).
2) Range and mean values of background metals for North Carolina soils taken from Elements in North American Soils by Dragun and Chekiri, 2005. Background Cd and Ag concentrations were taken from Southeastern and Conterminous US soils.
Soil concentrations are reported in milligrams per kilogram (mg/kg).
Compound concentrations are reported to the laboratory method detection limits.
Bold values exceed Residential Health -based PSRGs and for metals exceed Site -specific ranges of concentration and mean regional background concentrations
Underlined values exceed Industrial/Commercial PSRG
Laboratory analytical methods are shown in parentheses.
VOCs = volatile organic compounds; SVOCs = semi -volatile organic compounds; PCBs = polychlorinated biphenyls; UST = underground storage tank; AST = aboveground storage tank; ft bgs= feet below ground surface
NA = Not Analyzed; NS = Not Specified; -- = Not Applicable; BRL = below laboratory reporting limits
J = compound was detected above the laboratory method detection limit but below the laboratory reporting limit resulting in an estimated concentration.
B = Analyte is found in the associated blank as well as in the sample.
R-05=Laboratory fortified blank duplicate RPD is outside of control limits. Reduced precision is anticipated for any reported value for this compound.
MS-11 = Matrix spike recovery outside of control limits. Possibility of sample matrix effects that lead to a high bias for reported result or non -homogeneous sample aliquots cannot be eliminated.
MS-19 = Sample to spike ratio is greater than or equal to 4:1. Spiked amount is not representative of the native amount in the sample. Appropriate or meaningful recoveries cannot be calculated.
R-02 = Duplicate relative percent difference (RPD) is outside of control limits. Outlier can be attributed to sample non -homogeneity encountered during sample prep.
* Heterogeneous lithology in SB-6 (0-1) likely caused differences in concentrations of SVOCs, hexavalent chromium, and mercury in duplicate sample DUP-01 when compared to the SB-6 parent sample. SB-6 and DUP-1 soil samples were homogenized by the laboratory and re -analyzed for RCRA metals by EPA method 6020 A-B.
Soil samples from SB-6 and DUP-1 were outside of the hold times for re -analysis of SVOCs and hexavalent chromium and were therefore not re -submitted.

Contingency Plan
Contingency Plan
Wepak Property
Charlotte, North Carolina
Brownfields Project No. 21048-17-060
H&H Job No. MGN.002
This Contingency Plan is being provided as required by Part 9 of the NC DEQ template
Environmental Management Plan (EMP) for future redevelopment at the Wepak Property
Brownfields property located in Charlotte, Mecklenburg County, North Carolina (Site).
Current redevelopment plans for the Site include renovation of the existing Site buildings
for commercial uses and Site work activities such as concrete footing repair/replacement,
utility installations, and shallow grading for paved parking areas.
Contingency Actions
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 development activities,
the environmental actions noted below will be used to direct environmental actions to
be taken during these activities and sampling data for potentially impacted soil and the
disposition of impacted soil will be provided to DEQ when the data becomes available.
1. 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 IHSB Industrial/Commercial Use PSRGs will be
managed pursuant to this plan and incorporated into the Brownfields plat.
2. If determined to be warranted, confirmation samples will also be used to determine
the appropriate corrective measure for soil beyond the excavation limits required
for grading and/or utility line installation or removal. Such corrective measures are
specified in the items below.
3. 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 suitable
permitted facility or the waste will be managed in accordance with Paragraph 3 of
this section above, 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.
4. If buried piping is encountered and must be removed to allow installation to
proceed, the contractor will inspect the pipe for fluids, collect the fluids where
appropriate, and look for signs of a release using field methods. The collected
fluids will be sampled for VOCs, SVOCs, and RCRA metals to determine
appropriate disposition of the fluid.
5. In the event that soil within an excavation cannot be dried adequately for
construction purposes using the methods described above, the soil may be
amended with clean soil, aggregate, drying agents, and/or stabilizing agents to
achieve the desired geotechnical qualities or placed within the void space beneath
impervious surface cover. Amendment may be conducted inside or outside the
excavation and the material replaced into the excavation. If an amendment is used,
the type of amendment will be provided to DEQ for approval prior to its use. DEQ
will be notified prior to movement of the soil to other areas at the Site if results of
laboratory analysis for soil samples collected from the excavation indicate that
compound concentrations are detected above Industrial/Commercial Use PSRGs
(other than which are attributable to sampling or laboratory artifacts or which are
consistent with Site -specific background levels for metals).
6. In the event that impacts associated with an UST release are found to be present on
the subject Site, they will be addressed through the Brownfields Program.
