Y. EVAL UATIONAND RECOMMENDATIONS
1. Provide any additional narrative regarding your review of the application: This is a small-scale injection
intended to remediate a small plume of dissolved chlorinated solvents from a DOT asphalt testing lab. In terms
of potential receptors, there is one water supply well about 1500 feet away that is not likely to be impacted by
any injection activities. The facility and adjacent businesses are connected to municipal water supply.
Unnamed tributaries to Second Creek can be found to the south and east sides of the property; the closest to the
injection is to the east about 250 feet and it is also unlikely to be impacted by the injection given the volume of
injectant, distance and conductivity of the regolith. One issue is that the key monitoring wells, 35MW-1 and
35DW-1, have been partially covered by gravel & asphalt due to activities at the site. After scraping briefly
with a shovel, one of the well covers was visible and part of the pad of the other well was visible. These wells
need maintenance as they are in a traffic area — likely reconstruction of the protective covers and pads — but it
is possible they might need to be replaced if the wells have been damaged beyond repair. If replacement were
necessary, then a permit would be required from the MRO. Otherwise, the MRO sees no significant issues
with this proposal and recommends that it be permitted.
2. Attach Well Construction Data Sheet - if needed information is available
3. Do you foresee any problems with issuance/renewal of this permit? n Yes ® No. If yes, please explain
briefly.
4. List any items that you would like APS Central Office to obtain through an additional information request.
Make sure that you provide a reason for each item:

DWQ - A. uifer Protection
Table 3 provides a summary of the well construction for existing monitoring wells and proposed
temporary injection wells.
F.2 MONITORING PARAMETERS AND ANALYTICAL METHODS
During each sampling event, a set of site -wide water level measurements will be collected from
all monitoring wells. Each well to be sampled will then be purged and DO, ORP, specific
conductance, pH, and temperature measurements will be taken. Groundwater samples will then
be collected and submitted to a certified laboratory for analysis of VOCs (Method 8260 B), Total
Organic Carbon (Method 5310B), Nitrate (Method 353.2), Sulfate (Method 375.4).
F.3 MONITORING SCHEDULE
A groundwater monitoring event will be conducted prior to injection activities to act as a baseline
for evaluation of groundwater data. Post -injection monitoring will be completed at 1-month and
3-months following injection at the wells indicated in Section F.1. At approximately 6-month
post injection, groundwater monitoring will be conducted at all on -site monitoring wells.
G. WELL DATA
Well construction data for the existing monitoring well network and the proposed temporary
injection wells are presented in Table 3. A receptor survey conducted in 2004 by Hart &
Hickman did not identify any water supply wells within 1500 feet of the site.

SECTION V. ATTACHMENTS
A. SITE HISTORY
A.1 BACKGROUND
Site #35 is located on approximately 10.75 acres about one mile northwest of downtown
Rockwell, North Carolina at 500 Industrial Drive. Figure 1 shows the approximate location of
the site, and Figure 2 depicts the approximate site layout. The site formerly housed an NCDOT
asphalt testing facility and was an active asphalt plant until the early 1990s. The property is
currently owned by Bostco, LLC and is used as a vehicle maintenance facility with a small
adjacent aboveground storage tank (AST) farm containing fuel for the construction vehicles.
Historical information on the years of laboratory operation and solvent types and usage at this
location is not available. However, other NCDOT testing facilities in North Carolina generally
ceased operations in the early 1990s. NCDOT conducted on -site testing of asphalt at many
asphalt -producing facilities using American Society for Testing and Materials (ASTM) Method D
2172-88. The ASTM test method required the use of a solvent such as trichloroethene (TCE),
1,1,1-trichloroethane (1,1,1-TCA) or carbon tetrachloride (CT) to extract the petroleum binder
from the aggregate. The aggregate was then subject to a particle size gradation test.
According to NCDOT, on -site laboratories primarily used TCE and 1,1,1-TCA in progression
when the laboratory was in operation. The solvents were usually purchased new, and were reused
until they were no longer effective. Recycled solvents possibly containing impurities were also
used. Solvents stored, spilled or disposed of onsite near operating laboratories, resulted in
releases of chlorinated solvents to the environment.
The NCDOT entered into a memorandum of agreement with the North Carolina Department of
Environment and Natural Resources (NCDENR) Division of Water Quality's (DWQ)
Groundwater Section in 1999 outlining the objectives and procedures to be used in evaluating the
potential environmental impacts at former asphalt testing laboratories. Since that time, the
NCDENR has undergone a reorganization and the asphalt sites are currently under the
jurisdiction of the Inactive Hazardous Sites Branch (IHSB).

A.1.2 Environmental Assessments and Remedial Actions
An initial site screening conducted by NCDOT in 1989 indicated the presence of TCA and TCE
in a soil sample collected at an unspecified location. A comprehensive site assessment (CSA)
was conducted by Geraghty & Miller in 1996 and early 1997 which included a soil vapor survey,
soil and groundwater sample collection and analysis, installation of 10 monitor wells, surveying,
water level measurements, and aquifer testing. Results of the CSA indicated the possible
presence of target chlorinated solvents in the soil vapor samples in the vicinity of the former
asphalt testing laboratory. The Geoprobe® groundwater investigation identified the presence of
TCE, TCA, and 1,1-dichloroethene (1,1-DCE) at concentrations above the 15 NCAC 2L.0202
groundwater standards (NC 2L standards) in one groundwater sample collected in the vicinity of
the former asphalt testing laboratory.
The CSA concluded that the extent of TCE-impacted soils was horizontally delineated, but not
vertically delineated. In addition, the lateral extent of target chlorinated solvents had been
adequately defined for the shallow groundwater plume; however, the vertical extent of target
chlorinated solvents had not been fully defined.
In a letter dated July 1, 1997, the NCDENR issued written comments on the CSA submitted in
May 1997. The letter agreed with the CSA that the vertical extent of target chlorinated solvents
in soil and groundwater had not been adequately delineated. The letter recommended additional
soil sampling at the location of SS-3 to define the vertical extent of soil contamination, additional
monitor wells adjacent to or downgradient of SS-3 (the presumed source area), and an additional
deep monitor well to the east of 35MW-3 to define the horizontal extent of deep groundwater
contamination.
Solutions-IES conducted soil and groundwater sampling in August 2006 to complete the
delineation activities. An additional shallow monitoring well was installed in the presumed
source area. Soil samples were collected during well installation activities to define the extent of
soil contamination remaining in this area. In addition, two deep monitoring wells were installed
with the intent of delineating the horizontal extent of groundwater contamination in the western
portion of the site (35-DW6) and the vertical extent of contamination in the current groundwater
plume area (35-DW7).

B. HYDROGEOLOGIC DESCRIPTION
B.1 REGIONAL GEOLOGIC SETTING
The town of Rockwell is situated within the Carolina Slate Belt, part of the Piedmont
physiographic province. Bedrock within the Carolina Slate Belt is predominantly composed of
low grade metavolcanic rocks. The site is located in an area described as being underlain by
metavolcanic rock of interbedded mafic to felsic tuffs on the 1985 Geologic Map of North
Carolina (North Carolina Geologic Survey). The mafic rocks are described as medium grayish
green to dark green to black, fine -to medium -grained andesitic to basaltic tuffs and flows.
The typical Piedmont aquifer system is divided into three zones. These zones include the
unconsolidated saturated soil zone, the underlying saprolite and weathered bedrock. All three
zones are interconnected and act as a single aquifer system, although each zone varies in its
ability to transmit water (permeability). The base of the Piedmont bedrock aquifer is indistinct
and occurs where the fracture system is no longer effective in transmitting flow. The number of
fractures decreases with increasing depth, and often fractures are non -water bearing below a
depth of approximately 300 feet (Heath, 1980).
The site is specifically underlain by the Cecil Loam soil unit (CeB2) (NRCS Web Soil Survey
2.0). This soil type is described as: "sandy clay loam".
B.2 SIGNIFICANT CHANGES IN LITHOLOGY
The characteristics of the subsurface materials at the site were evaluated from the description of
onsite borings completed by Geraghty & Miller, as well as information obtained during the
installation of new monitor wells in July 2006 by Solutions-IES. Figure 3 shows the location of
cross sections across the site generated from historical and recent boring information. Figures 4
and 5 are cross sections showing the site lithology. Based on the boring logs, the subsurface
materials generally consist of 1 to 2 feet of fill material overlaying interbedded clays and silts to a
depth of approximately 15 feet and sandy silts to the top of a saprolite layer. The bedrock at this
site was encountered at approximately 50 ft bgs and was overlain by 1 to 5 feet of saprolite.
Numerous fractured zones were identified during the drilling of borings for the deep monitor
wells.

APPLICATION FOR PERMIT To CONSTRUCT AND/OR USE A WELL(S) FOR INJECTION
TYPE 51 WELLS -IN SITU GROUNDWATER REMEDIATION
SECTION V. ATTACHMENTS
At the site, the shallow aquifer includes surficial sediments and saprolite and has been delineated
during previous work at the site as land surface to approximately 50 ft bgs. The deep aquifer lies
below the 50 ft bgs depth and consists of a highly fractured zone to a depth of approximately 60 ft
bgs under which lies competent bedrock with few fractures.
B.2.1 Current Site Conditions
Only one well (35MW-1) screened in the shallow groundwater monitoring zone contained
concentrations of target compounds above the NC 2L standards during the February and August
2006 sampling events. TCE concentrations in 35MW-1 have been detected in concentrations
ranging from 1300 µg/L in February 2006, to 1800 µg/L in August 2006, while 1,1-DCE has
been detected at concentrations of 120 µg/L and 240 µg/L in February and August 2006
respectively.
Target compounds detected above the NC 2L standards in monitoring wells screened in the deep
aquifer include 1,1-DCE and TCE. Concentrations of 1,1-DCE have been detected in 35DW-1 at
concentrations ranging from 57 µg/L to 41 µg/L in February and August 2006 respectively. TCE
has historically been detected in 35DW-1 at concentrations as high as 820 µg/L, but has most
recently been detected at 310 µg/L in both the February and August 2006 events. In well 35DW-
2, concentrations of TCE appear to be decreasing, with the most recent concentrations being 21
µg/L and 20 µg/L, in February and August 2006 respectively. Table 1 provides a summary of
historical groundwater analytical data.
In summary, TCE and 1,1-DCE are the main target compounds presently detected in groundwater
at Site #35 at concentrations above the NC 2L standards. Target compounds were detected above
the NC 2L standards in monitor wells 35MW-1, 35DW-1, and 35DW-2 (Figures 6 and 7). Of
these wells, the most favorable conditions for reductive dechlorination were detected in 35DW-2.
Generally reducing conditions were also detected in 35DW-1. Based on current conditions, there
is some indication of natural biodegradation of TCE to cis-1,2-DCE in 35DW-1; however, in
35MW-1 and 35DW-2 there has been little change (or increase in TCE) with no appearance of
daughter products. In fact, the current TCE concentration in 35MW-1 is more than double the
1996 concentration. Conversely, in all three wells with target compounds, the concentration of

SECTION V. ATTACHMENTS
1,1,1-TCA has decreased appreciably since 1996 with the accompanying presence of 1,1-DCE,
which is an abiotic breakdown product of 1,1,1-TCA.
B.2.2 Lithology of the Injection Area
Based on the boring logs, the subsurface materials generally consist of 1 to 2 feet of fill material
overlaying interbedded clays and silts to a depth of approximately 15 feet and sandy silts to the
top of a saprolite layer. The bedrock at this site was encountered at approximately 50 ft bgs and
was overlain by 1 to 5 feet of saprolite. Numerous fractured zones were identified during the
drilling of borings for the deep monitor wells.
At the site, the shallow aquifer includes surficial sediments and saprolite and has been delineated
during previous work at the site as land surface to approximately 50 ft bgs. The deep aquifer lies
below the 50 ft bgs depth and consists of a highly fractured zone to a depth of approximately 60 ft
bgs under which lies competent bedrock with few fractures.
B.3 HYDROGEOLOGIC PARAMETERS USED FOR DESIGN
Groundwater at the site flows in a south to southeasterly direction in both the shallow and the
deep aquifer toward the unnamed creek located along the southeastern border of the property.
The water -level elevation data collected during the August 2006 sampling event were used to
create a potentiometric surface map of the shallow aquifer (Figure 8). The overall groundwater
gradient was estimated from the August 2006 water level data to be approximately 0.03 ft/ft in
the shallow aquifer and 0.007 ft/ft in the deep aquifer.
Geraghty & Miller estimated that the average hydraulic conductivity for the shallow aquifer was
0.79 ft/day and 25.54 ft/day in the bedrock aquifer. The average groundwater velocity at this site
was estimated to be 27 ft/year. Using a geometric mean hydraulic conductivity of 0.79 ft/day, an
average hydraulic gradient of 0.03 ft/ft between 35MW-2 and 35MW-4, and an estimate of 30
percent for porosity, the site -wide groundwater flow velocity is estimated as:
K Ah 0.79ft/day x0.03ft/ft=0.079ft/day

B.4 DEPTH TO MEAN SEASONAL HIGH WATER TABLE
During the most recent groundwater sampling event in August 2006 by Solutions-IES, the water
levels in the shallow aquifer ranged from 18.87 ft below top of casing (btoc); (elevation of 724.0
ft above mean sea level (amsl)) in MW-4 to 13.98 ft btoc (elevation of 731.17 ft amsl) in MW-7.
The water levels in the deep aquifer ranged from 17.69 ft btoc (elevations of 724.44 ft asml) in
monitoring well DW-4 to 16.28 ft btoc (elevation of 726.63 ft amsl) in DW-6. These values are
consistent with historical water levels recorded at the site. Table 2 provides a summary of the
historical water levels at this site.
C. INJECTION FLUB) COMPOSITION
The injection fluid is a stable emulsified -oil concentrate (EOS®) composed of food -grade soybean
oil, surfactants, amino acids, and vitamins blended to maintain a non -separated phase concentrate.
The concentrate will be diluted in the field with potable water to assist in distribution into the
aquifer. The emulsified liquid contains oil droplets in the 0.7 to 1.5 micron size range which
allow for ease of dilution, simplicity of injection and optimal subsurface distribution. The EOS®
will be handled according to the manufacturer's recommendations and in accordance with the
site's Health & Safety Plan. All materials used in the process are Generally Recognized As Safe
(GRAS) food -grade materials (21 CFR 184.1400). A Material Safety Data Sheet for EOS® is
included in Appendix A. The water source will be from a potable water supply obtained from
the City of Salisbury, which provides potable water to this area.
D. INJECTION RATIONALE
D.1 GOALS OF THE INJECTION PROJECT
The remediation goal for groundwater is to return it to its most beneficial use (which is drinking
water). The NC 2L Standards are proposed as the cleanup goals for groundwater. The goal of
this injection is to introduce a biodegradable organic substrate into portions of the aquifer with
high VOC concentrations to stimulate microbial activity and enhance reductive dechlorination of

dissolved chlorinated ethene contaminants present in groundwater at the site. Six injection wells
will be utilized for the injection of EOS®, chase water and Vitamin B-12. The well configuration
provides for two treatment zones with three injection wells per zone: one zone in the shallow
aquifer and one zone in the deep aquifer. The locations of the six proposed injection wells are
shown on Figure 9.
D.2 INJECTANT/CONTAMINANT REACTIONS
This project injects a biodegradable organic substrate into a contaminated aquifer. The
technology involves a one-time injection of slowly biodegradable, emulsified oil substrate
(EOS®). EOS® is a water miscible emulsion with an engineered droplet size that is prepared
using food -grade edible oils, surfactants, macro- and micronutrients. The EOS® process is
patented by Solutions-IES (U.S. Patent #US RE40,448E).
The emulsion is injected and distributed throughout the treatment zone using conventional
injection wells. The vegetable oil becomes trapped within the sediment grain pores leaving a
residual oil phase to support long-term anaerobic biodegradation of the target contaminants. As
the oil slowly biodegrades, it provides a continuous source of dissolved organic carbon to the
native microbial community to stimulate microbiological consumption of oxygen and production
of hydrogen. This reaction is illustrated generically in Equation 1:
(Eq. 1) C18H3202 (linoleic acid) + 34 H2O --Bacteria--> 18 CO2 + 50 H2
The organic substrate is the electron donor in this sequence of reaction. The hydrogen itself then
drives the desired anaerobic biological metabolism of the target contaminants by a second, more
specialized, group of microorganisms. These metabolic biotransfonnations are illustrated in
Equations 2 through 5 where hydrogen is used sequentially to replace each chlorine atom:
(Eq. 2) C2C14 (PCE) + H, -- Bacteria --> C,HC13 (TCE) + Cl + H
(Eq. 3) C2HC13 (TCE) + H, -- Bacteria --> C2H2C1, (DCE) + Cl + H+
(Eq. 4) C,H2C12 (cis%trans-DCE) + H2 -- Bacteria --> C2H3C1(VC) + Cl + H+
(Eq. 5) C2H3C1 (VC) + H2 -- Bacteria --> C2H4 (ethene) + CI + H+

Overall, four hydrogen molecules (4H2) are needed to completely dechlorinate the PCE molecule
to chloride.
D.3 MODELING AND TESTING RESULTS
Reductive dechlorination of chlorinated ethenes using a carbon source electron donor is a proven
groundwater remediation methodology. The amount of EOS® injected into the subsurface is
determined based on the concentrations of the target compounds (TCE and 1,1-DCE), the
concentrations of competing electron acceptors (i.e., dissolved oxygen, nitrate, sulfate,
manganese dioxide and ferric iron) and hydrogeologic conditions (i.e., subsurface lithology and
heterogeneity, hydraulic conductivity and effective porosity of the treatment zone). The available
site -specific information obtained from the Comprehensive Site Assessment (Geraghty & Miller,
1997) and testing by Solutions-IES in August 2006, were entered into the design spreadsheet
provided by EOS Remediation of Raleigh, NC. The design indicated that 5 drums
(approximately 1,300 lbs) of EOS® would be required to treat both injection zones. The design
life for this amount of substrate is approximately 3 to 5 years.
To optimize the injection process, the injection was designed to involve diluting the concentrate
10-fold as it is injected until all the EOS® has been placed in the aquifer. Then the EOS® is
further distributed away from each injection point using potable chase water.
EOS® has been thoroughly tested and is manufactured from food grade soybean oil, emulsifying
agents, micronutrients, vitamin B-12 and water. EOS® was used in a source area treatment
project at the Tarheel Army Missile Plant (TAMP) in Burlington, NC. In 2004, Solutions-IES
injected 13,000 pounds of EOS® concentrate into the 100 x 100 ft (30.5m X 30.5m) zone believed
to be the primary source area for the TCE plume. The EOS® treatment quickly stimulated
anaerobic conditions as evidenced by decreased dissolved oxygen, oxidation-reduction potential,
and sulfate concentrations and increasing ferrous iron, and methane. TCE was gone and only
degradation products were evident within one year of treatment. The regular monitoring program
confirmed the effectiveness of the selected treatment technology. Suitable conditions were
established for the contaminants to be reduced to non -chlorinated end -products.

E. INJECTION PROCEDURE AND EQUIPMENT
E.1 CONSTRUCTION PLANS AND MATERIALS
A total of six temporary injection wells will be installed to treat both the shallow and deep
treatment zones. Three shallow borings will be advanced drilled using Geoprobe® direct push
drilling techniques. The borings will be advanced to approximately 20 feet below ground surface
(ft bgs). The shallow injection wells will be constructed as 1-inch diameter PVC with 10 feet of
0.020-slot screen. An appropriately sized sand pack will be placed around the screen to
approximately 2 feet above the top of the screen. The remaining annular space will be backfilled
with bentonite pellets (periodically hydrated as they are added to the annular space) to within 3
feet of land surface. The last 3 feet of annular space shall be completed with a bentonite grout
cement mix.
In addition, three deep borings will be advanced using air -rotary drilling techniques. The borings
will be advanced to approximately 60 ft bgs. A temporary surface casing will be set during well
construction to prevent caving of the overburden. The deep injection wells will be constructed as
2-inch diameter PVC with 10 feet of 0.020-slot screen. An appropriately sized sand pack will be
placed around the screen to approximately 2 feet above the top of the screen. The remaining
annular space will be backfilled with bentonite pellets (periodically hydrated as they are added to
the annular space) to within 3 feet of land surface. The last 3 feet of annular space shall be
completed with a bentonite grout cement mix. After injection activities are completed, all of the
temporary injection wells will be abandoned.
Injection activities will be conducted in two phases, one phase will inject into the shallow aquifer
and the other phase will inject into the deep aquifer. For each phase of the injection process, the
wells will be manifolded together, but will have individual flow meters, gate valves and pressure
gauges. The Dosatron® diluter (or transfer pump) will be plumbed into a splitter that will allow
individual wells to be shut off from the injection process as needed. This will allow for the
control of pressure and flow rates of injection at each well. The manifold will be plumbed to a
Dosatron® with a potable water source (City of Salisbury) to provide dilution of the EOS®
concentrate. The Dosatron® will only allow a maximum total flow of 7 gpm. Therefore, to inject
three wells simultaneously the injection rate will be limited to 2 gpm per well.

TYPE 51 WELLS - IN SITU GROUNDWATER REMEDIATION
SECTION V. ATTACHMENTS
E.2 OPERATING PROCEDURES
Implementation of the process involves on -site blending of the EOS® concentrate with potable
water utilizing a Dosatron® water -powered proportional dosing pump. A Dosatron® will be set up
on a drum of EOS® via a flexible hose. Water from a fire hydrant will go through a City supplied
flow meter, then into the Dosatron® for use in diluting the EOS® to the proper 10:1 concentration
(10 parts water to 1 part EOS®). If the Dosatron® proportional dosing pump is unable to achieve
the design flow rate, alternative mixing and pumping approaches will be implemented.
Alternative designs may include using dilution tanks, chemical feed and transfer pumps to
conduct the injection.
The mixture will then be piped to the splitter where the injectant will be directed into flexible
hoses going to each well head manifold. Each braided hose line will have a flow meter to
determine the total volume of injectant going into each well. A gate valve and pressure valve at
each well manifold will allow field personnel to monitor and adjust flow rates and fluid pressures
during the injection process.
E.3 SYSTEM DESIGN
The EOS® solution will be injected into 6 temporary injection wells located down gradient of the
source area (Figure 9). The injection process will be performed during one mobilization in
several steps. EOS® concentrate will be diluted with potable water to a 10% concentration using
an in -line metering system. Approximately 505 gallons of dilute EOS® will be injected into each
of the 6 wells via the EOS® Metering System. Afterwards, approximately 1,000 additional
gallons of potable water will be injected to move the emulsion out into the formation away from
each well. If an injection rate of one gpm is achievable, then the injection should be completed
within approximately three days. However, if injection rates are significantly less, then additional
time in the field will be required. Figure 10 shows a schematic of the injection process.
E.4 INJECTION SCHEDULE
The injection is anticipated to occur during the Fall of 2008. The injection well installation
activities will commence within one month of receiving an approved UIC permit. The actual
injection of EOS® will occur within two weeks of the completion of the injection wells.

conductance, pH, and temperature measurements will be taken. Groundwater samples will then
be collected and submitted to a certified laboratory for analysis of VOCs (Method 8260 B), Total
Organic Carbon (Method 5310B), Nitrate (Method 353.2), Sulfate (Method 375.4).
F.3 MONITORING SCHEDULE
A groundwater monitoring event will be conducted prior to injection activities to act as a baseline
for evaluation of groundwater data. Post -injection monitoring will be completed at 1-month and
3-months following injection at the wells indicated in Section F.1. At approximately 6-month
post injection, groundwater monitoring will be conducted at all on -site monitoring wells.
G. WELL DATA
Well construction data for the existing monitoring well network and the proposed:temperry,
injection wells are presented in Table 3. A receptor survey conducted'in xxx by xxx did nod
identify any water supply wells within 1500 feet of the site.
