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): The polycyclic aromatic
hydrocarbons (PAHs) benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene,
dibenzo(a,h)anthracene, and indeno(1,2,3-cd)pyrene were detected in the northern portion of the
Site . The metal manganese has been detected in soil across the Site at concentrations ranging from
171 mg/kg to 624 mg/kg. Additionally, the metal arsenic was detected in the eastern, northeastern,
and southeastern portions of the Site at concentrations ranging from 2.6 mg/kg to 3.8 mg/kg. The
arsenic and manganese detections are consistent with Site-specific and/or regional background
4
EMP Form ver.1, October 23, 2014
levels. It is H&H’s opinion that the manganese and arsenic concentrations are background and not
associated with historical Site operations. The results of analysis of the soil samples are summarized
in Table 1 and Table 2. Soil sample locations and the proposed cut/fill analysis are provided on
Figure 3.
2) Depth of known or suspected contaminants (feet): The PAHs were detected in the northern
portion of the Site at depths of up to three ft below ground surface (bgs). Manganese has been
detected in soil borings across the Site and at depths ranging from ground surface to five ft bgs.
Arsenic has been detected in the eastern portion of the Site at depths ranging from one to six ft bgs.
3) Area of soil disturbed by redevelopment (square feet): An area of approximately 493,100
square feet will be graded and redistributed to level the property and to implement positive
drainage flow across the property. Grading activities will be conducted in accordance with
applicable local, state, and federal regulations including submittal of an erosion control plan
to Gaston County. The grading contractor will utilize 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 and berming) to manage soil on-
site during site redevelopment activities.
4) Depths of soil to be excavated (feet): Preliminary grading plans indicate soil will be cut to
depths of up to approximately 8 ft in the northwestern and eastern portions of the Site.
5) Estimated volume of soil (cubic yards) to be excavated (attach grading plan): Preliminary
grading plans indicate soil will be cut to depths of up to approximately 8 ft in the
northwestern and eastern portions of the Site and redistributed to level the property. A
preliminary grading plan with preliminary cut/fill analysis is provided in Appendix B.
6) Estimated volume of excavated soil (cubic yards) anticipated to be impacted by contaminants:
Soil assessment results have indicated limited areas of soil impacts are present at the Site.
Impacted soil will be managed on-site. Based on current grading plans, there will be up to
approximately four ft of cut soil in the north-central portion of the Site. To reduce the
potential for exposure to future Site occupants, soil cut from the north-central portion of
the Site in the vicinity of SB-2 will be cut, stockpiled separate from other cut soils, and
redistributed to an area to be covered by an impervious surface (e.g. asphalt parking lot,
building, or permanent hardscape).
7) Estimated volume of contaminated soil expected to be disposed of offsite, if applicable: N/A -
Based on the current preliminary grading plans, the Site is balanced and no soil is expected to be
disposed of off-site.

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)
6
EMP Form ver.1, October 23, 2014

If no, explain rationale: Soil analytical data does not indicate detections capable of exceeding
toxicity characteristic leaching procedure (TCLP) criteria using the Rule of 20.

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

Click here to enter text.

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: Typical construction dust control
measures will be utilized such as wetting with water trucks or hoses to manage nuisance dust
levels.

☒ Field Screening:
☒ Yes ☐ No
If yes, describe method; If no, explain rationale: During soil disturbance, the workers or
contractors will observe soils for evidence of a distinct unnatural color, strong odor, or fill disposed
materials of concerns (i.e., chemicals, tanks, drums, subsurface piping, 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 in Appendix C (Contingency Plan) will be implemented. In addition, the DEQ Brownfields
project manager will be contacted within two business days to advise that person of the condition.

☒ 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 and/or installation or removal of utilities,
excavation will proceed only as far as needed to allow grading and/or construction of the utility to
continue and/or only as far as needed to allow alternate corrective measures described below. Suspect
significantly impacted soil excavated during grading and/or utility line installation or removal may be
stockpiled and covered in a secure area to allow construction to progress. Suspect impacted soil will be
underlain by and covered with minimum 10-mil plastic sheeting. At least one representative sample of
the soil will be collected for analysis of total VOCs, SVOCs, and RCRA metals. If the results of analysis of
the sample indicate that the soil could potentially exceed toxicity characteristic hazardous waste criteria
7
EMP Form ver.1, October 23, 2014
using the Rule of 20, then the soil will also be analyzed for VOCs, SVOCs, and/or RCRA metals in
accordance with the Toxicity Characteristic Leaching Procedure (TCLP). Impacted soil will be handled in
the manner described below based upon the laboratory analyses:
1) 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 may be
used on-site as fill without condition.
2) If detectable levels of compounds are found which do not exceed the DEQ 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 (if analysis was
conducted), then the soil may be used on-site as fill without condition.
3) If detectable levels of compounds are found which exceed the DEQ 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 below at least two 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.
4) 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. Copies of the waste disposal
manifests will be provided to DEQ.
☒ 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:

☒ Analyze potentially impacted soil for the following chemical analytes:
☒ Volatile organic compounds (VOCs) by EPA Method 8260
☒ Semi-volatile organic compounds (SVOCs) by EPA Method 8270
☒ Metals RCRA List (8) (arsenic, barium, cadmium, chromium (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 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 (arsenic, barium, cadmium, chromium, lead, mercury, selenium, and silver). VOC and SVOC
concentrations will be compared to Residential PSRGs. Metal concentrations will be compared to
Residential PSRGs and/or site-specific levels.

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: Click here to 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

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. Click here to enter text.
If yes, provide specifications on barrier materials

Other comments regarding managing impacted soil in utility trenches: Although not anticipated, in
the event contaminated soil and/or vapors are encountered in the 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.

groundwater from excavations or foundations, containerizing, offsite disposal, discharge to sanitary
sewer, or sampling procedures): Based on the anticipated depth to groundwater, groundwater is not
anticipated to be encountered during any redevelopment activities. Although not anticipated, if
groundwater suspected to be impacted (based on strong odor, unnatural color, sheen, etc.) is
encountered during Site work, the contractor will contact the project environmental engineer to
observe the suspect condition. If the environmental engineer determines that the excavation likely
contains impacted groundwater, then appropriate worker safety measures will be undertaken to
manage groundwater that gathers in an open excavation within an area determined to be impacted
during construction activities. The accumulated water will be tested and disposed off-site at a permitted
disposal facility (if impacted), tested and discharged to the storm sewer (if not impacted above DEQ
surface water standards) per 2H .0106, or used for dust control at the Site. Discharge to the storm

Site Contingency Plan
Former Belmont Dyers
Brownfields Site
Belmont, North Carolina
Brownfields Project # 20094-16-036
H&H Job No. RPH-001

1.0 Introduction

This Contingency Plan has been prepared in accordance with Part 9 of the North Carolina
Department of Environmental Quality (DEQ) template Environmental Management Plan (EMP)
for the proposed redevelopment at the Former Belmont Dyers Brownfields Site located at 18
Linestowe Drive in Belmont, Gaston County, North Carolina (Brownfields Project # 20094-16-
036). The Site is comprised of two parcels totaling approximately 11.32 acres situated on the
western bank of the Catawba River. A Site Location Map is provided as Figure 1.

The Site is planned to be redeveloped with 70 townhouse units and 102 multi-family apartment
units, a leasing office, limited urban greenspace, asphalt-paved parking, and landscaped areas. A
preliminary Site plan is included in Appendix A. In order for redevelopment to take place
according to the current building plans, approximately 5,400 cubic yards of soil will be cut and
redistributed on-site to achieve the desired grades and implement positive drainage across the
Site. A preliminary grading plan with cut/fill analysis is included in Appendix B.

This Contingency Plan has been prepared to identify the management policies and field
procedures to be taken to address known and potential unknown environmental conditions during
redevelopment.

2.0 Procedures to Manage Soil Based on Known Conditions

2.1 Polycyclic Aromatic Hydrocarbon Impacted Soil

Results of previous assessment activities indicate that multiple polycyclic aromatic hydrocarbons
(PAHs), including benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene,
dibenzo(a,h)anthracene, and indeno(1,2,3-cd)pyrene were detected in shallow soil located in the
north-central portion of the Site (SB-2) at concentrations exceeding the DEQ Inactive Hazardous
Sites Branch (IHSB) Residential – Preliminary Soil Remediation Goals (PSRGs). PAHs have
not been detected in any other soil samples collected at the Site. To further evaluate the risks
associated with the PAH detections in SB-2, H&H used the DEQ Risk Calculator (August 2016
Version) to calculate cumulative risks for a residential-use scenario for compounds detected in
SB-2 (including metals which appear to be naturally occurring).

Cumulative risk calculator results indicate that the calculated lifetime incremental cancer risk
(LICR) for compounds detected in SB-2 is 5.8 x 10-5, which is within the acceptable risk range
of 1 x 10-4 to 1 x 10-6. In addition, the calculated non-carcinogenic hazard index (HI) is 0.17,
which is below the acceptable threshold of 1. Based upon the cumulative risk calculations, the
compounds identified in soil in SB-2 do not pose a significant risk for future residents.

Based on current grading plans, there will be up to approximately four ft of cut soil in the north-
central portion of the Site. To reduce the potential for exposure to future Site occupants, soil cut
from the north-central portion of the Site in the vicinity of SB-2 will be segregated, stockpiled
separate from clean soils, and placed under an impervious surface (e.g. asphalt parking lot,
building, or permanent hardscape).

3.0 Site Contingency Plan Based on Unknown Conditions

During construction activities, contractors may encounter unknown sub-surface environmental
conditions (i.e. tanks, drums, subsurface piping, or waste materials) that if encountered, will
require proper management.

In the event that such conditions are encountered during Site development activities, the tasks
noted below will be used to direct environmental actions to be taken during these activities.

1. During soil disturbance at the Site, the workers or contractors will observe soils for
evidence of impacted soil. Evidence of potential impacted soil includes a distinct
unnatural color, discoloration, strong odor, or observance of filled or previously disposed
materials of concerns (i.e. chemicals, tanks, drums, etc.). Should any of the above be
noted during Site work, the contractor will contact the project environmental professional
to observe the suspect condition. If the project environmental professional confirms that
the material may be impacted, then the procedures below will be implemented. In
addition, the environmental professional will contact the DEQ Brownfields project
manager within 48 hours of discovery to advise that person of the condition. H&H will
remain on call to provide assistance on an as-needed-basis.

2. If a previously unidentified underground storage tank (UST) is encountered during
redevelopment, it will be addressed in consultation with the Brownfields program. Site
workers will be instructed to look for signs of potential signs indicative of an unidentified
UST including buried piping, steel structures, and potential fill ports.

3. Suspect significantly impacted soil encountered during grading and/or utility line
installation or removal may be stockpiled and covered in a secure area on-site 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 by EPA Method 8260B, SVOCs by EPA Method
4
S:\AAA-Master Projects\Ralph Falls (RPH)\Task 2 - Brownfields\EMP\EMP_Former Belmont Dyers.doc
8270D, and RCRA metals by EPA Methods 6020/7471. 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 appropriate compounds in
accordance with the Toxicity Characteristic Leaching Procedure (TCLP). Based on the
results of laboratory analyses and specific operations planned in the vicinity of the
detected impacts, DEQ will be notified and additional sampling may be requested by
DEQ. Impacted soil will managed in accordance with the following paragraph.

4. Soil sampled in accordance with Paragraph 3 of this section and other soil to be removed
from this Site will be handled in the manner described below based upon the laboratory
analyses:

i. If detectable levels of compounds are found which do not exceed the
DEQ IHSB Protection of Groundwater and Residential PSRGs (other
than which are attributable to sampling or laboratory artifacts or which
are consistent with published regional background levels for metals)
and the TCLP concentrations are below hazardous waste criteria (if
analysis was conducted), then the soil may be used on-site as fill
without conditions or transported to a permitted disposal facility.

ii. 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 site-
specific background levels for metals) and the TCLP concentrations
are below hazardous waste criteria (if analysis was conducted), then
the soil, with DEQ’s approval, may be used on-site as fill below an
impervious surface, beneath at least two ft of compacted clean soil, or
transported to a permitted disposal facility.

5
S:\AAA-Master Projects\Ralph Falls (RPH)\Task 2 - Brownfields\EMP\EMP_Former Belmont Dyers.doc
5. If excavation of unexpected impacted soils occurs, confirmation sampling will be
conducted for purposes of recording areas of impacts remaining at the Site, if any, and to
determine if additional soil to be removed for construction should be managed as
impacted. It is anticipated that four sidewall soil samples and one base soil sample will be
collected as post-excavation confirmation samples. The confirmation samples will be
analyzed for VOCs, SVOCs, and RCRA metals. Areas of suspected contaminated soil
that remain at the Site after excavation is complete above the DEQ IHSB Residential
PSRGs shall be incorporated into the Brownfields plat.

6. With DEQ’s written approval, corrective actions shall ensure there is a barrier between
future Site visitors/occupants/workers and soil that remains in place, if any, at
concentrations above DEQ IHSB Residential PSRGs. The barrier may be a building,
paving, hardscape surface, or clean soil of a two ft minimum overlaying thickness. If
required, imported clean soil will be managed in accordance with the following
procedures.
If imported soil is brought to the Site for use as beneficial fill, to demonstrate that the
imported soil is suitable for use at a residential property, the fill soil will be sampled
before being brought to the Site. The number of samples to be collected will be
dependent upon whether the fill soil is obtained from a virgin or previously developed
property as follows:

i. If soil is obtained from a known permitted quarry, then one soil sample
will be collected from the borrow source prior to the soil being
transported to the Site.

ii. If fill soil is obtained from an off-site property that is not a known
permitted quarry, a sampling plan will be developed and submitted for
DEQ review. DEQ approval of the sampling plan and analytical
results is required prior to bringing soil on Site. The specific sampling
6
S:\AAA-Master Projects\Ralph Falls (RPH)\Task 2 - Brownfields\EMP\EMP_Former Belmont Dyers.doc
rate will be outlined in the above work plan, however generally if the
proposed borrow source has not been previous developed (i.e. virgin
land) soil samples at a rate of one per 500-1,000 cubic yards can be
used as an estimate.

iii. If the borrow source property has been previously developed, it should
be estimated that soil samples will be collected at a rate of
approximately one per 500 cubic yards.

iv. The borrow soil samples will be analyzed for VOCs, SVOCs, and
RCRA metals. Soil will be considered suitable for use at the Site if it
does not contain compound concentrations above DEQ IHSB
Residential PSRGs or site-specific background levels for metals.

7. If a sub-grade feature or pit is encountered and does not require removal for geotechnical
or construction purposes, it will be filled with soil or suitable fill and construction will
proceed. Where appropriate, the bottom may be penetrated before back filling to prevent
fluid accumulation. If the pit has waste in it, the waste will be set aside in a secure area
and will be sampled for waste disposal purposes for TCLP VOCs, TCLP SVOCs, and
TCLP RCRA metals and disposed off-site at a 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
observation of the waste indicate the concrete may potentially be contaminated, the
concrete will be sampled and analyzed for methods specified by the disposal facility.

8. 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 the abovementioned field methods. If the nature of the fluids
is unknown, the collected fluids will be sampled for VOCs, SVOCs, and RCRA metals to
7
S:\AAA-Master Projects\Ralph Falls (RPH)\Task 2 - Brownfields\EMP\EMP_Former Belmont Dyers.doc
determine appropriate disposition of the fluid. If buried piping is indicative of a UST,
reasonable efforts will be made to investigate if a buried UST is present.

9. 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. If
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 Residential PSRGs (other than which are
attributable to sampling or laboratory artifacts or are consistent with site-specific
background levels for metals.

10. In the event that groundwater is encountered during the redevelopment activities, the
groundwater may be allowed to evaporate in the excavation if possible. If that is not
practical, then the water will be pumped out of the excavation, containerized, and
sampled for laboratory analysis. Containers could be drums, poly tanks, or equivalent
depending upon the volume of the water. A representative sample of the water will be
analyzed for VOCs or other analyses based upon the suspected constituent, and managed
as follows depending upon the analytical results.

Dust Control
Dust will be controlled by keeping Site access roads and active work areas damp and by watering
or misting as necessary prior to and during grading activities. A water truck and/or appropriate
water misting equipment will be available if needed at the Site during work activities that may
suppress dust. Non-impacted stormwater or groundwater encountered during construction may
be used for dust control.
