Re: UIC Permit Application — -urn
Former NC DOT Asphalt Testing Site No. 18 �o
Dillsboro,North Carolina
H&H Job No. DOT-101 ro o0

Dear Mr. Kane:
On behalf of the North Carolina Department of Transportation (NC DOT), Hart & Hickman
(H&H) has prepared this Underground Injection Control Permit (UIC) application for injection
of a chemical oxidant and steam to remediate impacted soil and ground water at the former NC
DOT asphalt testing site (ATS No. 18) located at 1377 Macktown Road in Dillsboro, Jackson
County, North Carolina. The site is an active asphalt production plant owned and operated by
Harrison Construction, a division of APAC-TN. From approximately 1974 through 1989, NC
DOT operated an asphalt testing laboratory in the central portion of the site which used
chlorinated volatile organic compounds(VOCs).
Relatively high concentrations of NC DOT target compounds such as trichloroethene (TCE) and
1,1,1-trichloroethane (1,1,1-TCA) are present in soil and ground water near the former asphalt
testing laboratory. For example, TCE was recently detected at concentrations up to 1,100,000
µglkg in soil and up to 32,000 µg/1 in ground water near the source area. The goal of this
S.VAA-Mute Pmjew=DOTDOT-101 Dl&bom%UIC Perrtid CCom.doo

` Mr. Evan Kane
March 7, 2005
Page 2
injection is to reduce source area soil and ground water concentrations sufficiently to allow for a
monitored natural attenuation corrective action.
A portion of the source area is covered by above ground storage tanks (ASTs) within concrete
secondary containment. The ASTs contain petroleum fuels used in asphalt plant operations. In
addition, utilities are located in this area including high voltage power, telephone, and water
lines. The asphalt plant control room and the current asphalt testing laboratory are also located
in close proximity to the area of identified soil impacts.
On September 8, 2004, H&H met with the North Carolina Department of Environment and
Natural Resources (DENR) Asheville Regional Office to discuss remedial strategy for this site.
H&H proposed a short-term multi-technology approach using in-situ hydraulic fracturing with
potassium permanganate (a chemical oxidant), in conjunction with steam injection and air
sparging/vapor extraction. This in-situ treatment is expected to significantly reduce source area
soil concentrations and shallow ground water concentrations. DENR indicated that these
activities should be conducted as a pilot study. Then, a natural attenuation Corrective Action
Plan(CAP) could then be submitted if the event is successful.
H&H has subcontracted with Redox Tech, LLC of Morrisville, North Carolina to conduct the
injection. Because the injection area is near other structures including the petroleum ASTs
within concrete secondary containment, Redox Tech, LLC will have a structural engineer review
the potential for the proposed injection to affect nearby structures prior to the event.
The injection permit application form (GW-57REM) is attached along with supporting figures
and documentation.

Injection Description
rl
Chemical oxidant will be injected to address source area soil and ground water impacts. The
j oxidant will be potassium permanganate. Initially, potassium permanganate (8,000 lbs dry
weight) will be injected in a slurry while the soils will be hydraulically fractured between two
and twenty feet below grade. Steam injection will follow this step to remove residual chlorinated
VOCs by increasing their vapor pressure forcing the VOCs into the gas phase. Steam injection
will be performed in conjunction with air sparging and vapor extraction to remove the VOCs
from the subsurface. The entire injection process will take approximately 10 working days. The
procedure is described in more detail below.
A technical grade solution of potassium permanganate (10% by weight) is mixed prior to
injection. For this site, a Geoprobe® rig will be used to drive the injection casing and line and a
proprietary injection tool to 20 ft. The injection line and the Geoprobe® casing are slightly
pressurized (<20 psig)with the potassium permanganate solution. The Geoprobe® casing is then
pulled back to retract the outer casing and expose the injection nozzle. The pressure is then
increased until the formation fractures. The potassium permanganate is injected at approximately
_I 5 to 10 pro, and the injection pressure is expected to be approximately 75 to 100 psi. The
injection is accomplished using a double diaphragm pump. After an injection interval is filled,
_ the casing and the injection tool are lifted out approximately 2 to 3 feet, and another injection
interval is completed. This process is continued up to the surface. Potassium permanganate will
be injected in approximately 7 injection wells (Figure 8). A schematic of the equipment is
provided in Figure 11.
The potassium permanganate injection will coincide with steam and air injection in seven steam
injection points. The steam injection points will be constructed using 1/2" carbon steel coupled
pipe. The steam injection points are installed by driving 2 1/8" Geoprobe casing that has an
r.WatmrfilnlcaenunaprajeuMcdotWob101 di7k6woWk pmm6'v�jwion appGntion doammtatiaadoc
Hart&Hickman, PC

expendable tip on the bottom to a depth of 20 ft. The 1/2"pipe is lowered into the Geoprobe rod.
?approximately 2 feet of coarse sand is placed around the bottom of the hole. The steam point is
the completed by adding approximately 1 foot of bentonite, and grouted to the surface. The
steam is pushed into the injection points at approximately 300,000 BTU/hr. The steam will be
injected at approximately 250 °F and 100 psi. The steam generator will consume approximately
2 gpm of potable water obtained from a municipal water source and brought to the site. The
steam is injected until the desired temperature is obtained(30 to 40 Q. Air is also injected using
I the steam points to promote distribution of the steam and enhance volatilization. Unsaturated
zone vapors will be extracted using 11 vapor extraction wells. Steam/air injection and vapor
extraction will be performed for approximately 10 days.

APPENDIX B
Geology and Hydrogeology
A description of the regional and site geology and hydrogeology is provided below. The
summary provided below incorporates information obtained from published materials and field
activities conducted during site assessment.
� I
Regional Geology/Hydrogeology
According to the North Carolina Geological Survey 1985 Geologic Map of North Carolina, the
-- site area is located within the Blue Ridge Belt of North Carolina. Rocks in the area of the subject
property are characterized as biotite granitic gneiss, which is massive to well foliated, granitic to
quartz monzonitic; includes variably mylonitized orthogneiss and paragneiss, interlayered
amphibolite, calc-silicate rock, and marble.
In the Blue Ridge Belt, the bedrock is typically overlain by a mantle of weathered rock or
saprolite of varying thickness. The saprolite consists of unconsolidated clay, silt, and sand with
lesser amounts of rock fragments. Due to the range of parent rock types and their variable
r susceptibility to weathering, the saprolite ranges widely in color, texture, and thickness.
Generally, the saprolite is thickest near interstream divides and thins toward stream beds. In
profile, the saprolite normally grades from clayey soils near the land surface to highly weathered
rock above competent bedrock.
The occurrence and movement of ground water in the Blue Ridge Belt is within two separate but
interconnected water-bearing zones. A shallow water-bearing zone occurs within the saprolite
and a deeper zone occurs within the underlying bedrock. Ground water in the shallow
Yi g w saprolite
zone occurs in the interstitial pore spaces between the grains comprising the saprolite soils.
JGround water in this zone is typically under water table or unconfined conditions. Ground water
a:�nasty filvlaaa-nastvpmjaWnc do[Wot-101 d�bamkic pemitlmjvAion application docummWnndoo
Hart&Hickman,PC

movement is generally lateral from recharge areas to small streams which serve as localized
discharge points.
The occurrence and movement of ground water in the underlying water-bearing zone within the
crystalline bedrock are controlled by secondary joints, fractures, and faults within the bedrock.
_I On a regional scale, the direction of ground water flow is typically from highlands to major
streams and ground water sinks. The saprolite has a higher porosity than the bedrock and serves
as a reservoir supplying water to a network of fractures in the bedrock.
Site Geology and Hydrogeology
Soils encountered during H&H site assessment activities ranged from fine sandy silt and silty
fine sand. Shallow soils are compacted silty fill and are up to 30 to 35 ft thick. The fill material
is underlain by partially weathered rock and bedrock. Geologic cross-sections are provided as
Figures 8 and 9 with cross-section locations shown on Figure 2.
Monitoring well water levels were collected on December 19, 2003 (Table 1). The depth to
water ranged from approximately 7 ft below ground surface (bgs) in the northern portion of the
site to approximately 20 ft bgs in the southern portion of the site. The ground water elevation
data were used to prepare an estimated shallow ground water potentiometric map (Figure 3). The
r . potentiometric map indicates that ground water at the site generally flows to the southeast. This
flow direction is consistent with site topography(Figure 1).
Monitoring well clusters located at the site provide an indication of vertical gradient. Ground
water elevation data collected in December 2003 indicate a mixed vertical gradient (Table 2).
For example, the source area well pair MW-3/MW-lI and downgradient well pair MW-6/DW-1
data indicate upward vertical gradients while downgradient well pair MW-11/MW-2I data
indicate a downward vertical gradient.

Rising head slug tests were conducted by AWARE Environmental, Inc. (AWARE) for shallow
monitoring wells MW-3 and MW-5 as part of the Comprehensive Site Assessment (CSA). The
hydraulic conductivities using slug test data from monitoring wells MW-3 and MW-5 are
_r I approximately 0.20 May and 5.5 ft/day, respectively. The geometric mean hydraulic
conductivity of the slug test data is approximately 1.0 May or 3.5 x 104 cm/sec.
I
The hydraulic gradient is calculated to be approximately 0.15 ft/ft across the area of ground water
` I impacts. Using the mean hydraulic conductivity of 1.0 ft/day, the gradient of 0.15 ft/ft, and an
assumed effective porosity of 20%, the shallow ground water velocity is estimated to be
approximately 200 to 300 ft/year.

Proposed Monitoring and Schedule
I
{
Prior to the injection event, H&H will collect ground water samples to establish baseline
it
conditions. H&H will collect groundwater samples from select monitoring wells near the source
area (MW-1, MW-lI, MW-2, MW-3, MW-5, MW-10) and from the on-site water supply well.
I �
The samples will be submitted for laboratory analysis of VOCs by EPA Method 6230D. To
evaluate potential residual products from injection of potassium permanganate, H&H will
I analyze the samples for manganese and potassium. To further evaluate the effects of the multi-
technology event on a natural attenuation CAP, the samples will be analyzed in the laboratory for
the natural attenuation parameters total organic carbon, chloride, nitrate, sulfate, and methane;
and in the field for dissolved oxygen (DO), pH, temperature, conductivity, carbon dioxide,
oxidation-reduction potential (ORP), and ferrous iron.
i
After the multi-technology remediation event, H&H will collect samples from 4 soil borings in
r the source area to evaluate the remedy effectiveness. The borings will be installed by direct push
technology(DPT) to a depth of approximately 8 ft. Two soil samples will be collected from each
boring and submitted for laboratory analysis of VOCs by EPA Method 8260B.
Immediately following the multi-technology remediation event,H&H will collect a ground water
sample from MW-3 for analysis of VOCs by EPA Method 6230D. Approximately 30 to 60 days
after the multi-technology event, H&H will collect ground water samples from the same
1
monitoring wells used in the baseline sampling event, and these samples will be analyzed for the
_ same parameters mentioned above. These data will be evaluated to determine the success of the
multi-technology event and the viability of a natural attenuation CAP. Depending on the results,
'I additional ground water monitoring may be warranted after a period of approximately 6 months.
Future ground water monitoring needs will be determined at that time.

APPENDIX D
Water Supply Well Information
I
H&H surveyed the area within a 1,500-ft radius of the former testing laboratory in October 2003
! via visual reconnaissance and resident interviews. H&H located fifteen water supply wells and
two springs within 1,500 ft of the former laboratory, including the on-site water supply well
(Table 5 and Figure 7). Based on resident interviews, some wells and springs are shared between
residences. H&H also contacted the Tuckaseegee Water Authority which stated that public water
service is only available to the east of the site on the opposite side of the Tuckaseegee River.
In October 2003, H&H collected a sample from the on-site water supply well. The sample was
analyzed for VOCs by EPA Method 62301). No VOCs were detected in the on-site water supply
well. As part of the CSA, eight water supply wells (including the on-site water supply well)
and/or springs were sampled in 1997. No analyzed compounds were detected in those samples
(Table 6).
