A. SITE HISTORY
Site Usage Historically and Present: The Country Cupboard Sunoco is a retail gasoline
and convenience store located at the intersection of Jake Alexander Boulevard (Highway
601) and Statesville Boulevard (Highway 70) in Salisbury, North Carolina. The site is
triangular in shape and approximately one-half acre in size. The 2,000 square foot
convenience store occupies the western half of the property. The site has been occupied
by a retail gasoline station for at least 47 years. The site is currently operating as a
British Petroleum (BP) retail petroleum and convenience store.
Origin of the Contamination: The apparent source of groundwater contamination at the
site was identified as a combination of a leak from a gasoline UST that occurred in
October 1986 and an aboveground spill of approximately 146 gallons of unleaded
gasoline that occurred during refilling activities in June 1987.
Previous Remedial Action(s): IT Corporation submitted a Corrective Action Plan (CAP)
in August 1993. The CAP proposed the use of soil vapor extraction (SVE) to remediate
the hydrocarbon compounds at the subject site. Following approval of the CAP, the SVE
system was activated in April 1994. A CAP Addendum, submitted in October 1996,
proposed the use of air sparging technology to address dissolved -phase petroleum
hydrocarbons in groundwater. Following approval of the CAP Addendum, the air sparge
system was activated on June 11, 1997. The AS/VE system is located at the rear of the
convenience store building. The system consists of an air sparge compressor that injects
compressed air beneath the zone of groundwater contamination through 10 air sparge
wells (SP-1, SP-2, SP-3, SP-4, SP-5, SP-6, SP-7, SP-8, SP-9, and SP-10). The system
also includes a vacuum extraction blower for recovering petroleum hydrocarbon vapors
through nine vapor extraction wells (VP-1, VP-2, VP-3, VP-4, VP-4, VP-5, MW-1, MW-
4, MW-7, and RW-1). The extracted vapors are discharged to the atmosphere.
Through the end of August 2002, the AS/VE system was managed and operated by
Groundwater & Environmental Services (GES). ATC acquired the AS/VE system in
September 2002. In October 2002, ATC personnel visited the site and noted that the

system was not operating. ATC personnel were able to troubleshoot and restart the SVE
blower; however, the air sparge unit required more extensive repair work. After
replacing several parts and hiring a vendor to perform additional maintenance, ATC
personnel restarted the air sparge unit in February 2003.
The AS/VE system has been shut down since June 2007 while remedial alternatives are
being reviewed.
B. HYDROGEOLOGIC DESCRIPTION
Regional Geologic Setting: The Salisbury area is underlain by Paleozoic rocks of the
Carolina Slate Belt, which consist of granite, granodiorite, quartz monzonite, and a
mixture of granite and diorite. These rocks are generally fine to medium -grained and are
easily weathered producing a sandy, clayey saprolite. The saprolite may range in
thickness from a few feet to 50 feet.
Significant changes in lithology: None observed.
Hydraulic Conductivity, Transmissivity, and specific yield of the aquifer to be used for
injection, including a description of the test used to determine these parameters: A rising
head bail test was performed on well MW-3 in lieu of a groundwater pumping test to
assess aquifer characteristics of the saprolite. The bail test was performed on well MW-3
by quickly bailing water from the well until the well was nearly dry. Bailing was stopped
and rising water levels measured with an electric water level probe until the water level in
the well had recovered to near static conditions. A log drawdown versus time recovery
plot of water level data was prepared and evaluated using the Hvorslev method.
The hydraulic conductivity (K) of the saprolite in the vicinity of well MW-3 determined
from the bail test is approximately 1.34 gpd/ft3. This value is within the range for silt,

sandy silts, and clayey silts, and clayey sands presented in the literature. Assuming a
minimum saturated thickness (b) of the saprolite to be 50 feet, then by the relationship T
= Kb, the minimum aquifer transmissivity (T) is approximately 67 gpolft.
Depth to the Mean Seasonal High Water Table: Water levels have been measured at the
site for several years, and it is apparent that he mean water level is approximately 32 feet
below land surface.
C. INJECTION FLUID COMPOSITION
See attached RegenoxTM Brochure. MSDS Sheets for RegenoxTM Part A and
Regenox Part B are also attached.
D. INJECTION RATIONALE
Based on review of historical groundwater analytical data and current site conditions, it
appears that dissolved -phase constituents of concern are isolated to four monitoring well
locations (MW-3, MW-5, MW-6, and VMW-7). Remediation of these areas via active
mechanical remediation may not reduce the current concentrations to the groundwater
governing standards applicable to this site (NCDENR Groundwater Quality 2L Standards)
in an acceptable timeframe. As such, an advanced chemical oxidation technology is
proposed to more rapidly and effectively destroy the targeted groundwater constituents. The
chemical -oxidizing agent (RegenoxTM, which is on the NCDENR approved -chemical list)
will be introduced to the subsurface as a slurry solution via direct -injection (geoprobe grout
pump) using the above -referenced monitoring wells as injection points. Once introduced to
the subsurface, efficient oxidation reactions will occur as a result of three mechanisms
including surface mediated oxidation, direct oxidation, and free radical oxidation.
RegenoxTM, which produces minimal heat, will continue to affect the oxidation process for
up to 30 days on a single injection.

CHEMICAL OXIDATION REDEFINED...
RegenOx- is an advanced in situ chemical oxidation technology* designed to treat organic
contaminants including high concentration source areas in the saturated and vadose zones
PRODUCT FEATURES:
• Rapid and sustained oxidation of target compounds
Easily applied with readily available equipment •
Destroys a broad range of contaminants
.'10 More efficient than other solid oxidants
=u 3 Enhances subsequent bioremediation
ttA'i Avoids detrimental impacts to groundwater aquifers
RegenOx product application
HOW IT WORKS:
RegenOx maximizes in situ performance using a solid alkaline oxidant that employs a sodium percarbonate complex with
a multi -part catalytic formula. The product is delivered as two parts that are combined and injected into the subsurface using
common drilling or direct -push equipment. Once in the subsurface, the combined product produces an effective oxidation
reaction comparable to that of Fenton's Reagent without a violent exothermic reaction. RegenOx safely, effectively and rapidly
destroys a wide range of contaminants in both soil and groundwater (Table 1).
ACHIEVES RAPID OXIDATION VIA A NUMBER OF MECHANISMS
RegenOx directly oxidizes contaminants while its unique catalytic complex generates a suite of highly charged, oxidative free
radicals that are responsible for the rapid destruction of contaminants. The mechanisms by which RegenOx operates are:
=s Surface- Mediated Oxidation: (see Figure 1 and description below)
+ Direct Oxidation: C,CI, + 2 Na,CO, • 3 H2O, + 2 H2O -4--► 2CO2 + 4 NaCI + 4 H2O + 2 H2CO3
Free Radical Oxidation:
— Perhydroxyl Radical (H02')
— Hydroxyl Radical (OH-)
— Superoxide Radical (0,•)
Figure 1. Surface -Mediated Oxidation is
responsible for the majority of RegenOx
contaminant destruction. This process takes
place in two stages. First, the RegenOx activator
complex coats the subsurface. Second, the
oxidizer complex and contaminant react with
the activator complex surface destroying the
contaminant.

From Mass Reduction to Bioremediation:
RegenOx'" is an effective and rapid contaminant mass reduction technology. A single injection will remove significant amounts
of target contaminants from the subsurface. Strategies employing multiple Regenox injections coupled with follow-on accelerated
bioremediation can be used to treat highly contaminated sites to regulatory closure. In fact, RegenOx was designed specifically to
allow for a seamless transition to low-cost accelerated bioremediation using any of Regenesis controlled release compounds.
Significant Longevity:
RegenOx has been shown to destroy contaminants for periods of up to one month.
Product Application Made Safe and Easy:
RegenOx produces minimal heat and as with all oxidants proper health and safety procedures must be followed. The necessary
safety guidance accompanies all shipments of RegenOx and additional resources are available on request. Through the use of
readily available, highly mobile, direct -push equipment and an array of pumps, RegenOx has been designed to be as easy to
install as other Regenesis products like ORO' and HRC®.
Effective on a Wide Range of Contaminants:
RegenOx has been rigorously tested in both the laboratory and the field on petroleum hydrocarbons (aliphatics and aromatics),
gasoline oxygenates (e.g., MTBE and TAME), polyaromatic hydrocarbons (e.g., naphthalene and phenanthrene) and chlorinated
hydrocarbons (e.g., PCE, TCE, TCA).

Section 10 — Information on Toxicology
Toxicity Data
Sodium Silicate:
When tested for primary eye irritation potential
according to OECD Guidelines, Section 405, a similar
sodium silicate solution produced corneal, iridal and
conjunctival irritation. Some eye irritation was still
present 14 days after treatment, although the average
primary irritation score has declined from 29.7 after 1
day to 4.0 after 14 days. When tested for primary skin
irritation potential, a similar sodium silicate solution
produced irritation with a primary irritation index of 3 to
abraded skin and 0 to intact skin. Human experience
confirms that irritation occurs when sodium silicates get
on clothes at the collar, cuffs, or other areas where
abrasion may exist.
The acute oral toxicity of this product has not been
tested.
Ferrous Sulfate: LD50 Oral (rat): 319 mg/kg not a suspected carcinogen.

E. INJECTION PROCEDURE AND EQUIPMENT
Construction Plans and Materials: There will be no construction in order to complete the
proposed injections. All necessary equipment will be mobilized to the site, the injection
will take place, then all equipment will be removed from the site.
Operation Procedures: The proposed injection wells, MW-3, MW-5, MW-6, and VMW-
7, will be measured for Depth to Water, Temperature, pH, Oxidation -Reduction Potential
(ORP), Dissolved Oxygen (DO), Conductivity, and Alkalinity, then will be hooked up to
a pumping system that will be used to inject the Regenoxlm compound. See diagram
below:
ZEBRA
In Situ
Injection Setup
-od String Is advanced

Infection Probe
Assembly
Injection Chemical

The pumping system will include a gate valve downstream from the pump for restricting
the flow, which will, in turn, allow the operator to control the pressure. There will be a
pressure gauge mounted on the injection manifold for monitoring pressure. The flow rate
and total flow volume will be measured with an in -line flowmeter, similar to the type
used for residential water supply lines.
Water quality parameters (pH, Temp, Conductivity, DO, ORP, and Alkalinity) will be
measured continuously throughout the injection, as well as at the conclusion of each
event.
Planned Injection Schedule: The first injection event will take place upon approval of
this permit application, and the second and third injection events will take place at 30 day
intervals afterward.
F. MONITORING PLAN
Monitoring of monitoring wells MW-3, MW-5, MW-6, and VMW-7 is proposed on a
quarterly basis to assess the effectiveness of the application of RegenoxTM. The first
quarterly post -injection monitoring event will be conducted approximately 30 days
subsequent to the date of injection. Data collected during the post -injection monitoring will
be summarized and presented in a quarterly groundwater monitoring letter report.
Groundwater samples will be analyzed by EPA Method 624 including B'1'P,X, MTBE,
DIPE, EDB, and Naphthalene. Additionally, pH, DO, temperature, ORP, and alkalinity
measurements will be collected from the above -referenced monitoring wells during
monitoring events subsequent to the injection.
