The site was operated as a manufacturer of dental equipment by Pelton & Crane Company from
approximately 1955 to 1992. In the late 1990s and early 2000s, soil, groundwater, soil gas, indoor air,
and sediment/surface water impacts were detected at the site and the site was listed on the North
Carolina Inactive Hazardous Sites list (Pelton & Crane Site, NCD055162069). Metals, volatile organic
compounds (VOCs), and polynuclear aromatic hydrocarbons (PAHs) have been detected in site soil at
concentrations exceeding regulatory screening levels. Assessment and remediation at the site are
being conducted in accordance with an Administrative Agreement for Registered Environmental
Consultant (REC) Directed Assessment and Remedial Action between Siemens and the North Carolina
Department of Environmental Quality (DEQ). Previous remedial activities performed at the site have
included soil excavation and off‐site disposal and groundwater remedial injections.
Portions of the proposed shallow construction excavation along the western side of the site building
will be within the extent of a previously excavated area near the former western baghouse,
wastewater treatment area, and original plating Area 1. Approximately 3,500 tons of impacted soil
were removed from this area during Phase I Remedial Action activities conducted in 2006. Depths of
the 2006 excavation ranged from approximately 18 inches to 72 inches below the ground surface.
Results of confirmation soil samples collected from the base and sidewalls of the excavation indicated
that compound concentrations were below the site specific protection of groundwater remedial goals
and/or background concentrations. The excavation area was backfilled with imported clean soil upon
completion of the remedial action. Therefore, the proposed shallow construction excavation along
the western side of the building will primarily be in clean backfill soils in areas previously remediated.
Details associated with the 2006 remedial action activities conducted in the vicinity of the western
side of the building are documented in the Second Quarter 2006 Remedial Action Quarterly Progress
Report prepared by Advanced Geoservices Corporation dated October 6, 2006.
Several existing groundwater monitor wells are located in the vicinity of the proposed shallow
excavation areas. The general contractor conducting site work will identify the locations of
monitoring wells in the vicinity of the proposed excavation areas and demark the wells with traffic
barrels and flagging. To minimize the potential for damaging or destroying the existing site monitor
wells, the PD modified the construction plans for the sidewalks, footers, and depressed curbs to be in
compliance with the Media Disturbance requirements stipulated in the Siemens Access and Indemnity
Agreement and Temporary Use Restriction document. Site work and associated excavations will be
at least 5 feet from existing monitoring wells (see Figure A‐111 attached).
4) Which category of risk‐based screening level is used or is anticipated to be specified in the
Brownfields Agreement?
☐ Residential ☒ Non‐residential or Industrial/Commercial
Note: If children frequent the property, residential screening levels shall be cited in the Brownfields
Agreement for comparison purposes.
5) Schedule for Redevelopment (attach construction schedule):
a) Phase I start date and anticipated duration (specify activities during each phase):
Interior Renovations: Beginning 6/13/2016 ‐ TBD
Shallow excavation site work: 6/27/2016 – 7/12/2016
b) If applicable, Phase 2 start date and anticipated duration (specify activities during each
phase): NA

c) Additional phases planned? If yes, specify activities if known:
Yes ☐ No ☒ Not in the foreseeable future ☐ Decision pending☐
d) Provide the planned date of occupancy for new buildings: TBD
CONTAMINATED MEDIA
Contaminated Media (attach tabulated data summaries for each impacted media and figure(s) with
sample locations): Tabulated data tables and figures pertinent to the proposed construction activities
are provided in Appendix B.
Part 1. Soil: ☒ Yes ☐ No ☐ Suspected
Part 2. Groundwater: ☒ Yes ☐ No ☐ Suspected
Part 3. Surface Water: ☐ Yes ☐ No ☒ Suspected
Part 4. Sediment: ☐ Yes ☐ No ☒ Suspected
Part 5. Soil Vapor: ☒ Yes ☐ No ☐ Suspected
Part 6. Sub‐Slab Soil Vapor: ☐ Yes ☐ No ☒ Suspected
Part 7. Indoor Air: ☒ Yes ☐ No ☐ Suspected
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): A Construction Plan (A‐111)
depicting the locations of proposed shallow excavation areas is included in Appendix A. Tabulated
summary of pertinent soil sample data from previous reports and maps depicting the soil sample
locations are provided in Appendix B. Historically, metals, PAHs, and chlorinated solvent compounds
have been detected at concentrations exceeding regulatory screening criteria in proposed excavation
areas located west of the site building. However, soil in this area was excavated and disposed of off‐
site as part of 2006 remedial action activities. Post excavation confirmation soil samples indicate that
concentrations of compounds of concern were below site specific protection of groundwater
remediation goals and/or established site‐specific background concentrations. The excavation basins
were subsequently backfilled with imported clean soils. Limited soil assessment activities have been
conducted on the south side of the site building where additional proposed shallow excavations are
planned for installation of new footers and depressed curbs. However, the area south of the facility
has historically been utilized for parking and it does not appear that manufacturing activities occurred
on this portion of the site.
2) Depth of known or suspected contaminants (feet):
As discussed above, impacted soils were excavated from depths ranging from 18 to 72 inches below
the ground surface along the western side of the site building. Analytical results of post excavation
soil samples collected from the base and sidewalls of the excavation did not indicate that impacts
remained at levels exceeding the site specific remediation goals and/or established site‐specific
5
background concentrations. Proposed excavation depths on the western side of the facility range
from approximately 1 ft to 3 ft below the current grade. The proposed excavation depths in this area
of the site are not expected to exceed the base of the 2006 excavation.
3) Area of soil disturbed by redevelopment (square feet): Approximately 1,100 sq ft (see Construction
Plan in Appendix A).
4) Depths of soil to be excavated (feet): Excavation depths for the sidewalk proposed for the western
side of the Site building and the depressed curbs proposed south of the building are anticipated to be
approximately 4 inches to 12 inches below grade. Excavation depths for ramp footings proposed for
the western side of the building and column footings proposed for the southeastern corner of the site
building are anticipated to be approximately 3 ft below grade.
5) Estimated volume of soil (cubic yards) to be excavated (attach grading plan): A Construction Plan
is included in Appendix A. Approximately 45 to 50 cubic yards of soil will be disturbed during the
proposed shallow excavation activities.
6) Estimated volume of excavated soil (cubic yards) anticipated to be impacted by contaminants: The
majority of the proposed excavation activities will be conducted in an area west of the Site building
where previous excavation activities were performed to remediate impacted soils. The excavation
was backfilled with clean imported soils. As such, it is anticipated that the excavation extents
proposed here will be predominantly conducted in clean backfill material and no contact with
impacted soil is anticipated. However, the general contractor will perform excavations in accordance
with the Media Disturbance terms outlined in the Access and Indemnity Agreement and Temporary
Use Restriction document including oversight by Hart & Hickman personnel.
7) Estimated volume of contaminated soil expected to be disposed offsite, if applicable: Disposal of
impacted soils at off‐site locations is not anticipated at this time. If off‐site impacted soil disposal is
warranted, then it will be conducted in accordance with the procedures identified below.
IMPORTED FILL SOIL
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? Unknown at this time.
3) If yes, what is the depth of fill soil to be used at the property? Unknown at this time.
If a range of depths, please list the range.
4) PRIOR TO ITS PLACEMENT AT 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), or attach existing data: If needed, imported fill soil will
be analyzed for the following constituents:
☒ Volatile organic compounds (VOCs) by EPA Method 8260
☒ Semi‐volatile organic compounds (SVOCs) by EPA Method 8270
6
☐ 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 and Analytical Method:
☐ Known borrow material (DESCRIBE SOURCE AND ATTACH SAMPLING PROFILE): If fill soil is
obtained from a portion of an off‐site property that has not been previously developed (i.e., virgin land),
DEQ will be contacted to discuss sampling protocol based on estimated volume of import soil. At least
one soil sample will be collected from the borrow source prior to the soil being transported to the site.
The soil sample will be analyzed for VOCs, SVOCs, and Priority Pollutant List metals plus hexavalent
chromium. Soil will be considered suitable for use at the site if it does not contain compound
concentrations above DEQ IHSB Residential PSRGs or typical background levels for metals. If fill soil is
obtained from a portion of an off‐site property that has been previously developed, then soil samples will
be collected at a rate of approximately one soil sample per 400 cubic yards. The soil sample will be
analyzed for VOCs, SVOCs, and Priority Pollutant List metals plus hexavalent chromium. Soil will be
considered suitable for use at the site if it does not contain compound concentrations above DEQ IHSB
Residential PSRGs or typical background levels for metals.
MANAGING ON‐SITE 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 and volumes are acceptable, if only preliminary data
available). A Construction Plan is included in Appendix A. Soil excavated at the site will be used as
backfill under the proposed ramp located along the western side of the building. Per the terms
stipulated in Access and Indemnity Agreement and Temporary Use Restriction, Section(viii),
construction in excavation areas will be completed and/or the excavation basin will be closed within
30 days of soil extraction.
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).
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
7
BE RE‐USED ON SITE AND MUST BE DISPOSED OF IN ACCORDANCE WITH NCDEQ 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). If no, explain rationale:
Historical analytical results from the site did identify soil that was considered to be a characteristic
hazardous waste. However, the characteristically hazardous soil was removed from the site and analytical
results of post excavation confirmation soil samples indicate that concentrations are well below
hazardous levels. Furthermore, the soils that were identified as characteristically hazardous, were located
beneath the site building. No media disturbance activities are planned beneath the site building.
☐ 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)
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 on‐site location and capped, removed offsite):
☐ Preliminary Health‐Based Residential SRGs
☒ Preliminary Health‐Based Industrial/Commercial SRGs April 2016
☐ 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: Significant areas of contaminated soil are not
expected to be encountered or disturbed during site redevelopment activities based upon previous soil
sampling data and the Construction Plan. 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.
Soil piles will be covered with plastic sheeting when not in use (and overnight) to control dust levels and
stormwater erosion. In the unlikely event that potentially impacted soil is encountered during site
redevelopment that requires excavation, particular attention will be paid by contractors to implement
dust control measures and soil will be managed as described below.
☒ Field Screening:
☒ Yes ☐ No
If yes, describe method; If no, explain rationale: During soil disturbance activities at the site, the
workers, contractors, and environmental consultant will observe soils for evidence of potential
significantly impacted soil that may not be suitable to leave in place in exposed areas at a commercial use
8
site. Evidence of potential significant impacted soil includes a distinct unnatural color, strong odor, or
observance of filled or previously disposed materials of concerns (i.e. chemicals, tanks, drums, etc).
Should the above be noted during site work, then the procedures below will be implemented. In addition,
the environmental consultant will contact the DEQ Brownfields project manager within one business day
to advise of the condition.
☐ Soil Sample Collection:
☐ Yes ☒ No
If yes, describe method (e.g., in‐situ grab, composite, stockpile, etc.); If no, explain rationale:
H&H does not anticipate collecting additional soil samples based on previous site assessment activities. If
significant impacted soil 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. Per the term stipulated in Access and
Indemnity Agreement and Temporary Use Restriction, Section 10(iv), the excavation area will be secured
and adequately covered with plastic when not being actively managed until work is completed. At least
one representative sample of the soil stockpile will be collected for analysis of total VOCs, SVOCs, and
Priority Pollutant List 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 for toxicity characteristic leaching procedure TCLP VOCs, TCLP SVOCs, and/or TCLP RCRA
metals. Impacted soil will be handled in the manner described below based upon the laboratory analyses:
i. If no organic compounds are detected in a composite sample (other than which are attributable to
sampling or laboratory artifacts) and metals are consistent with 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’s written approval, may be used on‐site as fill below an impervious surface, or beneath at least 2 ft
of 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, 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. In the unlikely event that the composite 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.

☐ Other:
☐ Final grade sampling of exposed soil (i.e., soil that will not be under buildings or permanent
hardscape): [if not checked provide rationale for not needing] Disturbed areas will be covered
with impervious surfaces upon completion of site work activities. Therefore, no final grade/post‐
construction sampling is proposed.
Provide diagram of soil sampling locations, number of samples, and denote Chemical Analytical
Program with check boxes below (Check all that apply):

☒ Other Constituents & Analytical Method:
OFF‐SITE 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: Off‐site disposal of impacted soils is not
anticipated at this time; however, if grading specifications are not met, off‐site disposal options
will be considered.
☒ Landfarm or other treatment facility: Off‐site disposal of impacted soils is not anticipated at
this time; however, if grading specifications are not met, off‐site disposal options will be
considered.
☐ Use as Beneficial Fill Offsite – provide justification:
☒ 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: DEQ approval will be obtained prior to export and placement of
site soils on another suitable Brownfields site.
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 □
If no, include rationale here.
If yes, provide specifications on barrier materials
11
Other comments regarding managing impacted soil in utility trenches: Although not anticipated, in the
event contaminated soil and/or vapors are encountered in potential utility trenches during
redevelopment activities, the trench will be evacuated and appropriate safety screening of the vapors will
be performed to protect workers. If results indicate further action is warranted in response to vapors to
protect workers, appropriate engineering controls (such as use of industrial fans) will be implemented.
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? Based on historical groundwater
gauging data, depth to groundwater is approximately 5 to 16 ft below ground surface at the site.
Is groundwater known to be contaminated by ☒ onsite ☒ offsite ☒ both ☐ or unknown sources?
Describe source(s): Extensive groundwater sampling has been performed at the site since 2004, and has
continued through present as part of on‐going performance monitoring of groundwater remedial action
activities. The selected remedial action for the site is enhanced bioremediation (injection of a vegetable
oil emulsion) combined with monitored natural attenuation. Based on recent groundwater analytical
data, VOCs detected in groundwater at concentrations above 2L Groundwater Quality Standards include
benzene, tetrachloroethene (PCE), trichloroethene (TCE), 1,1‐dichloroethane (1,1‐DCA), 1,2‐
dichloroethene (1,2‐DCE), methylene chloride, and vinyl chloride. Long‐term monitoring will continue in
accordance with Underground Injection Control (UIC) Permit Number WI0300225. Recent groundwater
analytical data, a sample location map, and isoconcentration maps for select COCs are included in
Appendix B.
What is the direction of groundwater flow at the Brownfields Property? Based on historical groundwater
gauging data, groundwater flow in shallow overburden soils and shallow bedrock is generally to the west‐
northwest. Consistent with groundwater flow in the shallower zones (overburden soils and shallow
bedrock) the deep bedrock groundwater flow is believed to flow to the west‐northwest. Recent
potentiometric maps for the three groundwater zones are included in Appendix B.
Will groundwater likely be encountered during planned redevelopment activities? ☐ Yes ☒ No
If yes, describe these activities: Proposed redevelopment activities are associated with shallow
excavations for installation of sidewalks, footings, and depressed curbs planned for areas along the
western and southern sides of the existing site building. Locations and depths of the proposed shallow
excavations are depicted on the Construction Plan (Figure A‐111) included in Appendix A. Proposed
excavation depths on the western and southern sides of the facility range from approximately 1 ft to 3 ft
below the current grade. Based on groundwater gauging data, the proposed excavation depths along the
western and southern sides of the site building will not encounter the shallow water table which is
estimated to be approximately 5 to 8 ft below ground surface in this area of the site.
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, if shallow groundwater is encountered during
site work, the contractor will contact the project environmental consultant to observe the suspect
condition. If the project environmental consultant determines that the excavation has likely encountered
shallow groundwater, then appropriate worker safety measures will be undertaken to manage
12
groundwater that 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 addition, the environmental consultant will contact the DEQ Brownfields project manager
within one business day to advise that person of the condition.
PART 3. SURFACE WATER – Please fill out the information below.
Attach a map showing the location of surface water at the Brownfields Property. A small unnamed
tributary is located in the southwestern portion of the site. Laboratory analytical data for samples
collected from the tributary during Remedial Investigation activities indicate that metals were detected
in surface water at concentrations that exceed standards. A tabular summary of historical surface water
sample analytical results and a figure depicting sample locations are included in Appendix B.
Is surface water at the property known to be contaminated: ☒ Yes ☐ No Previous investigations
have included collection of surface water samples along the unnamed tributary. Metal constituents have
been detected above standards in surface water.
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): Per the terms stipulated in Access and
Indemnity Agreement and Temporary Use Restriction, Section 10(v), steps shall be taken to prevent any
untreated stormwater runoff to come into direct contact with exposed soil or excavation areas.
Specifically, soil stockpiles and excavated areas will be covered with plastic, and temporary berms will be
placed around open areas to prevent surface water from entering an excavated area. If surface water
run‐off gathers in an open excavation in which impacted soil is present, 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).
PART 4. SEDIMENT – 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. Analytical
results of sediment samples collected from the unnamed tributary located in the southwestern portion of
the site in the early and mid‐2000s indicated that several metals were detected at concentrations
exceeding site specific remediation goals and background concentrations. The impacted sediment in the
unnamed tributary was excavated in 2006 as part of remedial action activities. Analytical results of post
excavation confirmation sediment samples collected in June 2006 indicate that metal concentrations did
13
not exceed site specific remediation goals or background concentrations. Tabular summaries of historical
sediment and post excavation confirmation sediment sample analytical results are included in Appendix
B. Additionally, figures depicting the locations of the sediment samples are included in Appendix B.
In the event that contaminated sediment is encountered during redevelopment activities, list activities
for management of such events (stream bed disturbance): Not Applicable.
PART 5. 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:
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 (Appendix A) showing the location of soil vapor contaminants exceeding site screening
levels.
If applicable, at what depth(s) is soil vapor known to be contaminated? Approximately 5 to 6 ft below
the current grade.
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: Given
that the areas where soil vapor were identified above screening levels are on the opposite side of the site
building from the proposed excavation activities, it is unlikely that workers will encounter contaminated
soil vapor during redevelopment. Although not anticipated, in the event contaminated soil vapors are
encountered during redevelopment activities, the area will be evacuated and appropriate safety screening
of the vapors will be performed. If results indicate further action is warranted, appropriate engineering
controls (such as use of industrial fans) will be implemented.
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 (Appendix
C) showing the location of these exceedances.
14
At what depth(s) is sub‐slab soil vapor known to be contaminated? ☐ 0‐6 inches ☐ Other, If other
describe: Not applicable.
Will workers encounter contaminated sub‐slab soil vapor during planned redevelopment activities?
☐ Yes ☒ No ☐ Unknown Based on the proposed redevelopment activities covered in this EMP,
it is not anticipated that workers will encounter potential contaminated sub‐slab soil vapors during
construction activities.
In the event that contaminated soil vapor is encountered during redevelopment activities, list activities
for management of such contact: Not Applicable
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: Although not anticipated, in the event that impacted indoor air vapors
are encountered during redevelopment activities, the work area will be evacuated and appropriate safety
screening/sampling of the indoor air will be performed. If results indicate further action is warranted to
protect workers, appropriate engineering controls (such as use of industrial fans) will be implemented. In
addition, the environmental consultant will contact the DEQ Brownfields project manager within one
business day to advise that person of the condition.
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.
Attach the plan.
Has the vapor mitigation plan been approved by the NC Brownfields Program?
☐ Yes ☐ No ☐ Unknown
Has the vapor mitigation plan been signed and sealed by a North Carolina professional engineer? ☐
Yes ☐ No
15
What are the components of the vapor intrusion mitigation system?
☐ Sub‐slab depressurization system
☐ Sub‐membrane depressurization system
☐ Block‐wall depressurization system
☐ Drain tile depressurization system
☐ Passive mitigation methods
☐ Vapor barriers
☐ Perforated piping vented to exterior
☐ Other method: Click here to enter text.
PART 9. CONTINGENCY FOR ENCOUNTERING UNKNOWN TANKS, DRUMS, OR OTHER WASTE
MATERIALS
Please provide a contingency plan in the event unknown tanks, drums, fuel lines, landfills, or other
waste materials are encountered during site activities.
If a sub‐grade feature or pit is encountered and does not require removal for geotechnical or construction
purposes, it will be filled with soil or suitable fill and construction will proceed. Where appropriate, the
bottom may be penetrated before back filling to prevent fluid accumulation. If the pit has waste in it, the
waste may be set aside in a secure area and will be sampled for waste disposal purposes for TCLP VOCs,
TCLP SVOCs, and TCLP metals and disposed off‐site at a permitted facility or the waste will be managed in
accordance with Part 1 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.
If buried piping is encountered and must be removed to allow development 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.
In the event that impacts associated with an underground storage tank (UST) release are found to be
present on the subject site, they will be addressed through the Brownfields Program.
If buried materials or other waste materials which do not appear to be hazardous are identified at the
site, then the material will be left in place unless it needs to be removed for geotechnical purposes. The
locations of the materials will be documented in the final EMP Report. If the non‐hazardous waste
materials need to be removed, they will be disposed off‐site. If buried materials appear to be hazardous
(such as buried drums), then grading will stop and a plan for managing the materials will be developed for
DEQ approval.
Check the following activities that will be conducted prior to commencing earth‐moving activities at
the site:
☐ Review of historic maps (Sanborn Maps, facility maps)
☐ Conduct geophysical surveys to evaluate the location of suspect UST, fuel lines, utility lines, etc.
☐ Interviews with employees/former employees/facility managers/neighbors
