PERMIT ISSUANCE MEMO

FROM: John McCray
RE: Permit To Inject Oxygen (ISOC)
Former Terrell Shell gasoline station Site
I recommend that Permit Number WI0300154 be issued to Acme of South Carolina to inject Oxygen to remediate
groundwater contaminated with hydrocarbons.
SITE DESCRIPTION Hydrocarbons were released to the groundwater through the use of a former UST operated by
a gas station. Contaminants have been known to be in the soil and groundwater at the site since 1995. Prior remedial
activity at the facility has consisted of air sparging and soil vapor extraction. Currently the site is being used as a
location for commercial buildings. Contamination is located within the matrix of sandy saprolite and within the
groundwater of the surficial aquifer, extending into the upper limit of the bedrock. Groundwater flow across the site
diverges off of a groundwater ridge and is moving contaminants to the west-southwest and to the north-west.
HYDROGEOLOGIC DESCRIPTION The site is located within the inner Piedmont Physiographic Province and is
underlain primarily by saprolitic sand and clayey sand derived from underlying bedrock. Within the constraints of the
site, the surficial aquifer is contained within the saprolite and extends down into the fractures of the bedrock (Figures
4 and 5). The average depth to groundwater is 40 feet below ground surface, and it flows to the west-southwest
around to the north-west off of a groundwater ridge under a hydraulic gradient of .013 ft/ft through an aquifer with a
hydraulic conductivity of approximately 0.65 ft/day. The average velocity for groundwater under these conditions is
approximately .04 ft/day.
EXTENT OF CONTAMINATION Contaminant distribution of hydrocarbons for concentrations above the
NCGWQS, within the surficial aquifer based on the most recent sampling event, has a biaxial distribution. The
contaminant plume extends to the west-southwest and to the north-west from a point near the MW-2 area. The
contamination plume extending to the west-southwest is — 200 ft. long and —50 ft. wide, whereas the plume extending
to the north-west is —130ft. long and —76 ft. wide. The plume extends to an overall depth of —80 ft. below ground
surface in the vicinity of monitoring well MW-2D.
PROPOSED INJECTION The applicant proposes to inject oxygen at a moderated pressure to maintain a
dissolved oxygen concentration of 20 to 40 parts per million into the surficial aquifer through 3 shallow and 2 deep
monitoring wells outfitted with ISOC units over a period of five years. The total volume of injectant comprises a
negligible percentage of the injection area.
HOW IT WORKS The main remedial activity of the dissolved oxygen is to provide an electron receptor to cause
degredation of the hydrocarbons.
MONITORING Seven (7) existing monitoring wells located at the site currently being used to monitor for
changes in contaminant concentrations as part of ongoing activities at the site will be used to monitor the injection.
Sampling for constituents will be conducted quarterly using wells MW 1R, MW 1 D, MW5R, MW6, MW9R, MW 13,
and MW 15 in order to measure field parameters pH, dissolved oxygen, oxygen -reduction potential (ORP), .
temperature, and conductivity and to conduct laboratory analysis for VOCs using EPA Method 6200B, sulfate and
nitrate by EPA method 300, alkalinity by EPA method 310.1, methane by RSK SOP-75, dissolved iron, biological
oxygen demand (BOD), and chemical oxygen demand (COD) by appropriate methods. Monitoring will continue for
five years (Table 5).
EPIDEMIOLOGY On May 21, 2002, the DHHS' Epidemiology Branch provided comments on the use of
Oxygen to enhance bioremediation of petroleum groundwater contaminants. Dr. Luanne K. Williams did not present
any information that would preclude the use of these products for injection but did provide a health risk analysis and
worker safety precautions, which are in Part X of the attached permit.
REGIONAL OFFICE COMMENTS Maria Schutte of the Mooresville Regional Office recommended issuance of this
permit upon satisfactory response to an NOV issued for well construction violations.

groundwaters.
(B) The entire depth of each well shall be sounded before it is sealed to insure freedom from
obstructions that may interfere with sealing operations.
(C) The well shall be thoroughly disinfected, prior to sealing, if the Director determines that
failure to do so could lead to the contamination of an underground source of drinking
water.
