formation. Based on available information, soil impacts are expected to primarily be within 15
feet below land surface (bls).
3) Area of soil disturbed by redevelopment (square feet): Approximately 6.51 acres. See attached
drawings.
4) Depths of soil to be excavated (feet): Excavation activities will generally be limited within 15
feet below the current land surface.
S) Estimated volume of soil (cubic yards) to be excavated (attach grading plan): Undetermined at
this time, however, the site Is expected to be near neutral which will limit the amount of soil
that will need to be exported from a construction standpoint.
6) Estimated volume of excavated soil (cubic yards) anticipated to be impacted by contaminants:
Unknown at this time, but impacts will likely be limited to the general footprint of the existing
building as existing Phase II assessment data does not indicate the presence of gross
Impacts to soil and groundwater.
7) Estimated volume of contaminated soil expected to be disposed of offsite, if applicable: The
volume of impacted soil expected to be disposed of offsite is currently estimated to be less
than 750 cubic yards.

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 hereto 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
❑ 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: Available Phase II assessment data does not indicate the presence of
gross impacts to soil and that impacts are likely limited to common petroleum constituents and
degreasing agents used in automotive repair.
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):

EMP Form ver.1, October 23, 2014

❑ Site -specific risk -based cleanup level, or acceptable concentrations determined via
calculated cumulative risk. Enter details of methods used for determination/explanation:
Click here to enter text,
S) Check the following action(s) to betaken during excavation and management of said soils:
® Manage fugitive dust from site:
® Yes ❑ No
If yes, describe method; If no, explain rationale: Excavation areas will be monitored for
visible dust and total volatile organic compounds using a photoinionization detector. Although
petroleum impacts from dust are not anticipated, construction activities will include the use of
common dust suppression activities, such as the use of water, as needed.
® Field Screening:
® Yes ❑ No
If yes, describe method; If no, explain rationale: Localized areas of impacted soils are
expected to be encountered immediately under the concrete slab to the existing building during
building demolition and around former UST locations. The floor drain system and oil/water
separator will also need to be decommissioned/cleaned prior to removal and it is expected that
impacted soils may be encountered during their removal. It is also possible for additional USTs to
be identified during demolition which may require UST closure activities to be conducted. During
these activities, personnel under the direct supervision of a N.C. licensed PE or PG will be on -
site to screen soils in the field for evidence of impacts to determine the extent of excavation
activities. Soil sampling (as described below) will be conducted to confirm that excavation
activities have removed impacted soil below applicable residential screening levels. Soils will also
be screened for evidence of petroleum or other potential impacts during construction excavation
and site grading activities on other portions of the site. Field screening will include the use of a
PID for both headspace analysis of selected soil samples and ambient air monitoring. See
attached drawing for known and potential contaminant source locations and the GIS overlay map
showing the estimated depths of grading and excavations. All field screening visits will be
documented with field notes and photographs to be submitted with the final EMP compliance
deliverable.
® Soil Sample Collection:
® Yes ❑ No
If yes, describe method (e.g., in -situ grab, composite, stockpile, etc.); If no, explain rationale:
Initial Phase Il assessment results indicate that releases of petroleum and common degreasing
agents have occurred under and around the perimeter of the existing building, floor drain and
oil/water separator system and former UST locations. Field screening will be used to primarily
confirm that impacted soil has been removed. Conformation soil samples will be collected at the
extents (sidewalls and base) of soil excavation areas where contamination is found and will be
analyzed for volatile organic compounds (VOCs) using EPA Method 826013, semi -volatile organic
compounds (SVOCs) using EPA Method 8270D and RCRA 8 Metals using EPA Method 6020B
and 7471A. Results will be compared against PSRGs for the purpose of evaluating
environmental risk for constructions workers and future site occupants. Existing data and
analysis of impacted soil will be used to allow impacted soils to be directly loaded into trucks for
off -site disposal at a permitted facility. In the unlikely event that unknown impacted soils are
6
EMP Form ver.1, October 23, 2014

encountered during construction that are not representative of previously assessed soils, these
soils will be stockpiled in general accordance with NCDEQ guidance. The stockpiled soils will be
sampled per applicable NCDEQ guidance for waste characterization for eventual off -site disposal
at a permitted facility or possible re -use as on -site fill subject to laboratory test results and
Brownfields Program approval. At a minimum, stockpiles soils will be analyzed for VOCs using
EPA Method 8260B and SVOCs using EPA Method 8270D and Resource Conservation and
Recovery Act (RCRA) Metals, including hexavalent chromium speciation. If additional USTs are
identified, closure sampling will be conducted per UST Program guidance. Additional laboratory
analyses may be selected for Brownfields Program approval based on field characteristics of the
impacted soil and selected disposal facility requirements.
® 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:

® Other Constituent(s) & Analytical Method(s): As described above, additional
analyses may be required based on field characteristics of additional impacted soil (if any) and
selected disposal facility requirements. Brownfields Program approval will be obtained prior regarding
the use of additional analytical methods to characterize impacted soils.
® Proposed Measures to Obtain Pre -Approval for Reuse of impacted Soil within the
Brownfields Property Boundary

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 Soil documented to be impacted that is deemed
unusable at the site will be disposed of at a landfarm qualified to accept the types of documented
impacts encountered. Soil profiles of the impacted soil media to be disposed will be provided to
the landfarm, and a certificate of disposal/disposal manifests will be provided to McAdams upon
receipt of impacted soil.
❑ Use as Beneficial Fill Offsite —provide justification: Click hereto enter text.
❑ 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: Click here to enter text.
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.
8
EMP Form ver.1, October 23, 2014

® 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 o No a
If no, include rationale here. No — No evidence of gross impacts have been detected. Excavation
of impacted soil beneath the building and at known/potential contaminant sources will be
excavated to remove additional impacted soil. As such, the installation of barriers to be protective
of utilities Is not anticipated. However, as noted in Part 8, an active vapor intrusion mitigation
system (VIMS) will be installed for this site as a proactive measure due to the low levels of
chlorinated solvents detected in groundwater.
If yes, provide specifications on barrier materials
Other comments regarding managing impacted soil inutility trenches: Click hereto enter text.
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? Approximately 2 to 13 feet. Varies
across site due to Triassic Basin geologic formation. These conditions are likely associated with
perched and or artesian groundwater conditions.
Is groundwater known to be contaminated by ®onsite ❑ offsite ❑ both ❑ or unknown
sources? Describe source(s): Common petroleum and degreasing constituents, such as MTBE,
TCE and PCE were identified in groundwater at relatively low concentrations. No evidence of
gross impacts were observed.
What is the direction of groundwater flow at the Brownfields Property? Undetermined, but likely to
the west based on topography.
Will groundwater likely be encountered during planned redevelopment activities? ® Yes ❑ No
If yes, describe these activities: Perched groundwater will likely be encountered during foundation
and utility installation. According to Report of Subsurface Investigation (Revised for proposed
grades) document prepared by GeoTechnologies, Inc. (April 6, 2017), the worst -case scenario
depth at which the foundation system will be set is to the top of partially weathered rock (PWR).
The depth to PWR varies widely onsite. PWR was encountered at depths ranging between 3.5 to
9.5 feet below land surface (BLS) in the eastern portion; and 8 to 18.5 feet BLS in the western
portion of the site in which the current dealership is located. Groundwater was found at
approximately 7 to 13 feet BLS in three of the test boreholes installed in the northern portion
where PWR was relatively shallow in two of the three borings (at depths of 4, 18.5 and 3.5 feet
BLS). In the southern portion of the site, PWR is much softer and varied in depth anywhere
between 15 and 25 feet BLS. Based on the geologic characteristics of the Triassic Basin,
groundwater infiltration, if any, into excavations is likely to be limited.
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): If groundwater is encountered, sampling may be conducted to
determine if it is impacted (Using Standard Method 6200E for VOCs and EPA Method 8270 for
SVOCs). The primary method for handling water will be to use techniques to displace the water
9
EMP Form ver.1, October 23, 2014

within excavations to avoid the need to pump the water from the excavations. If water will need to
be pumped from the excavation, a separate plan will be developed for Brownfields Program
approval that will include the methods for pumping, containerization, treatment, transport and
disposal (as needed). The plan will be developed to meet construction needs and to be
protective of construction workers and future site occupants.
PART 3. SURFACE WATER — Please fill out the information below.
Attach a map showing the location of surface water at the Brownfields Property.
Is surface water at the property known to be contaminated: ❑ Yes ® No
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): Excavation of impacted soils
(as previously described) will occur at start of construction activities to remove potential
contaminant sources that could impact surface and storm water during construction. In the
unlikely event that additional contaminant sources are identified during construction, plastic
sheeting (if needed) will be placed over the surface of the impacted soil to prevent rainwater from
coming into contact with the impacted soil until it can be excavated into stockpiles or directly into
trucks for off site disposal. If needed, the site will be graded to direct runoff into construction
stormwater pond to prevent potentially impacted stormwater from migrating off -site. If a rain
event occurs that causes stormwater to flow across impacted soil, soil from impacted areas will
be screened, sampled and managed in accordance with the requirements described under Part 1
(Soil) of this EMP.
1�4.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
If yes, attach a map showing location of known contaminated sediment at the property.
In the event that contaminated sediment is encountered during redevelopment activities, list
activities for management of such events (stream bed disturbance): It is highly unlikely that
sediment will be encountered during construction based on current site characteristics. See item
No. 3 (Surfacewater) for managing surfacewater and potential impacted soils.
IF —
PART S. SOIL VAPOR -- Please fill out the information below.
Do concentrations of volatile organic compounds at the Brownfields property exceed the following
vapor intrusion screening levels in the following media:
10
EMP Form ver.1, October 23, 2014

IHSB Residential Screening Levels:
Soil Vapor: ® Yes ❑ No ❑ Unknown
Groundwater: ❑ Yes ® No ❑ Unknown
IHSB Industrial/Commercial Screening levels:
Soil Vapor: ❑ Yes ® No ❑ Unknown
Groundwater: ❑ Yes ® No ❑ Unknown
Attach a map showing the location of soil vapor contaminants that exceed site screening levels.
If applicable, at what depth(s) is soil vapor known to be contaminated? Shallow soil gas samples
were collected during a previous 2016 Phase II assessment. Relatively low concentrations of
PCE was identified in a soil gas sample below its residential VISL in 2016. Soil gas sampling was
limited to two locations along the edge of the current building. There is limited information
regarding the magnitude and extend of soil vapor impacts at the site.
Will workers encounter contaminated soil vapor during planned redevelopment activities?
® 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: Soil
vapor impacts will be encountered and managed during the excavation of impacted soils at the
start of construction activities as previously described in this EMP. As available Phase II
assessment data do not indicate the presence of gross impacts, this work will likely mitigate the
risk of soil vapor impacts during the following phases of construction.
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

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: Click here to enter text.
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: See Part 5 description regarding excavation of
petroleum impacted soil. This work will be conducted at the start of construction activities which
will include the demolition of all existing building structures. Removal of the impacted soil will also
11
EMP Form ver.1, October 23, 2014

remove source area soils to minimize potential sub -slab soil vapor impacts for proposed
redevelopment.
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: Note: due to the presence of PCE and TCE in soil
and/or groundwater, limited Phase II assessment data regarding the magnitude and extent of
potential vapor intrusion impacts and difficulties in collecting representative samples (based on
site geology) to determine if there could be an unacceptable vapor intrusion risk for the proposed
building, an active vapor intrusion mitigation system (VIMS) will be designed and installed for the
subject site as described in Part 8. As of the date of this EMP, the VIMS is in the process of
being completed for Brownfields Program review and approval.
