Subject: Rescission of NPDES General Permit
Permit Number NCG510242
Circle K Stores, Inc. #5117
Mecklenburg County
Dear Mr. Belin:
6
Reference is made to the May 1, 2003 letter from ATC Associates requesting rescission of the
subject NPDES General Permit. The letter states that the site has been given a low priority ranking and
the groundwater treatment system has been shut down, removing the need for continued permit
coverage. In accordance with this request, NPDES General Permit NCG510242 is rescinded, effective
immediately.
Please be advised that this permit rescission is based wholly upon your statement that the
activities which would require general permit coverage at the site have ceased or been eliminated.
Division staff has not visited the site to obtain independent verification. Operating a treatment facility,
discharging wastewater or discharging specific types of stormwater to waters of the State without a valid
NPDES permit will subject the responsible party to a civil penalty of up to $25,000 per day. Enforcement
action will be certain for persons that have voluntarily relinquished permit coverage when, in fact,
continuing permit coverage was necessary. lf, in retrospect, you feel the site still requires permit
coverage, you should notify this office immediately. Furthermore, if in the future you wish to again
discharge to the State's surface waters, you must first apply for and receive a new NPDES permit.
If you have questions about this matter, please contact Bob Sledge at [phone], extension
547 or the Water Quality staff in our Mooresville Regional Office at [phone].
Sincerely,
lec

GENERAL:
The facility was last inspected on May 22, 2002, by Ms. Crystal Taylor of the Mecklenburg County
Water Quality Program (MCWQP). A Compliance Evaluation Inspection :Report was issued on June 10
2002.
PERMIT:
The general permit for the facility expires on September 30, 2006. The site is engaged in the
remediation of groundwater contaminated with gasoline. The groundwater remediation system (GWRS)
consists of an oil/water separator, air stripper rack, bag filter, and two carbon adsorption units in series.
The permit authorizes the discharge of treated groundwater to Briar Creek, a class C stream, in the
Catawba River Basin. The permitee should contact the Division of Water Quality and request the rescission
of the permit.
RECORDS/REPORTS:
Discharge Monitoring Reports (DMRs) are not required to be submitted. The facility did not
discharge during the review period; therefore, no laboratory analysis has been performed.
FACILITY SITE REVIEW:
All of the major components of the facility were not in service and were not operating at the time of
the inspection_ The system has not operated since October 25, 2001 due to the decrease in groundwater level
in the recovery wells.
FLOW MEASUREMENT:
Flow measurement at the facility is accomplished using a Master Meter mechanical flow gauge. The
tlow measurement device is acceptable under the current permit.
LABORATORY:
Because the GWRS has not been operational for the duration of the current inspection period, the
facility did not have an effluent discharge during this time frame. Therefore, no effluent laboratory analysis
has been perforrned.
EFFLUENT/RECEIVING WATERS;
The facility was not discharging at the time of the inspection.
SELF -MONITORING PROGRAM:
The review period is from March 2002 through February 2003. The facility did not discharge
during the review period. Submittal of Discharge Monitoring Reports (DMR) is not required for the GR WS
at the facility.
OPERATIONS & MAINTENANCE:
The facility is adequately secured.

PART IV - EVALUATION AND RECOMMENDATIONS
BP Oil Company requests an NPDES General Discharge Permit for
the discharge of treated groundwater from a proposed groundwater
remediation facility located at the junction of East Harris
Boulevard and Plaza Road in northeastern Charlotte, Mecklenburg
County. Groundwater has been contaminated with petroleum products
due to overfilling of the storage tanks. Recovered groundwater
will be treated via a proposed remediation facility which will
consist of an oil/water separator, an air stripper, and two
activated carbon adsorption units prior to discharging to a storm
sewer along Plaza. Road. The storm sewer may be tributar to Brier
Creek.
Since the proposed facility is located in the Charlotte -
Mecklenburg area, the applicant may need approval from the
Mecklenburg County Department of Environmental Protection (MCDEP)
for possible air emissions..
Pending final review and concurrence by the SERG and MCDEP, it
is recommended that an NPDES Individual Permit with toxicity limit
(if necessary) be issued to the applicant in lieu of the requested
General Permit.

1.0 INTRODUCTION
Page 1
In August, 1993, BP Oil Company (BP) initiated a Comprehensive Site Assessment at the site (please
refer to Figure 1 for the Site Location Map). The Assessment was completed in October, 1993 with a
subsequent Assessment Addendum completed in March 1994.
This report details a Corrective Action. Plan prepared in accordance of North Carolina Department of
Environment Health and Natural Resources (NCDEHNR) guidelines to target remediation of the
groundwater to the 15A NCAC 2L standards, or as close thereto as is economically and technologically
feasible. Table 1 presents the most recent hydrocarbon concentrations identified in the groundwater.
Various technologies were considered for the removal of the dissolved hydrocarbons in the groundwater
underlying the site, Table 2 lists the advantages and disadvantages along with cost effectiveness for
various aquifer restoration systems. After evaluation of these technologies, it is recommended that a
pump and treat groundwater recovery and treatment system be utilized for remediation of this site.
The system will consist of a recovery well, water table depression pump, oil water separator, air stripper
and granular activated carbon columns for recovery and treatment of the hydrocarbon -impacted
groundwater beneath the site. The treated groundwater will be discharged to the municipal storm sewer,

20 SITE DESCRIPTION
2.1 Site Location
Page 2
BP Site No. 24768 is located at the intersection of Harris Boulevard and Plaza Road approximately five
miles east of downtown. Charlotte, Mecklenburg County, North Carolina. The population of the area is
estimated to be 511,000, in an area of mixed commercial development and some residential areas.
Currently, the site is open and operating as a retail service station with a car wash. The building is
situated between residential units to the north, vacant lots to the south and to the west and BP Procare
across Hams Boulevard to the east.
The subject BP site currently has three 10,000 gallon fiberglass underground storage tanks (USTs) which
store three grades of unleaded gasoline,
2.2 Regional Geology and mHydrogeoIogx
The subject site is located in the Piedmont Physiographic Province of North Carolina. Specifically, the
site is located within the Charlotte Belt and is reportedly underlain by diorite -granite complex. The
effects of lithology and rock structure on topography are mostly subtle. The rocks of the Piedmont are,
for the most part, metamorphosed and deeply weathered. Outcrops are most common in stream bottoms
and on the steeper slopes with deep weathering in the uplands.

2.3 Site Geology and Hydrogeology
Page 3
The water table aquifer beneath the facility was encountered approximately 18 feet below grade level
(BGL) with a reported flow direction to the west, towards Brier Creek. Groundwater elevations in the
monitor wells were calculated, and were used by Land Tech Remedial to estimate the direction of
groundwater flow and the gradient of the water table surface in the uppermost aquifer identified in the
Comprehensive Site Assessment (CSA). The hydraulic gradient was reportedly estimated at 0.0083 Wft
(feet per foot), See Land Tech Remedial CSA dated 10/93 and CSA addendum dated 3/94
3.0 CORRECTIVE ACTION PLAN OBJECTIVES
3.1 Corrective Action Plan Objectives
The objectives of the Corrective Action Plan are to prevent migration of the hydrocarbon plume toward
private potable wells in the immediate area of the site and to target the remediation of groundwater to the
NCAC 2L standards. A groundwater table depression pump will be installed in recovery well OW-4
Pumping from this well will create a capture zone in the area of the highest MTBE concentrations in
groundwater and help prevent further migration of the hydrocarbon plume. Based upon the plume size,
configuration, and estimated aquifer characteristics; one recovery well is proposed at this time. During
the first quarter of operation, the system effectiveness will be evaluated, additional recovery wells will be
proposed if deemed necessary. Soil remediation activities are not proposed for this site since no
hydrocarbon concentrations measured in soils are above agency action levels (Land Tech Remedial, Inc.,
1994).

4. 0 DESIGN OF CORRECTIVE ACTIONS SYSTEM'
4.1 Recovery Well Details
Page 4
There is one recovery well located at the subject site (OW-4). This is a six inch diameter well installed to
a total depth of 30 feet, The well is screened from 30 feet below grade level (BGL) to 10 feet BGL.
Static water level was reportedly measured to be 19 76 feet BGL on February 7, 1994 in this well.
4.2 Pump Selection
Based upon estimated aquifer characteristics, a Grundfos model 5E12 1/2 HP groundwater recovery
pump was selected for this site. The recovery system will consist of the water table depression pump and
automatic level controls. The control panel for the system will be located in a recovery compound shed
Water will be pumped to an oil/water separator, gravity drained to a low profile aerator, pumped through
granular activated carbon (GAC) and finally discharged to the storm sewer under an NPDES permit,
Free phase product has not been encountered at this site, however, an oil/water separator has been
specified to meet the NPDES permitting requirements.
The water table depression (WTD) pump was selected based on the estimated flow rate combined with
the total head that the pump must produce to overcome the forces of gravity and friction, Component
headloss was calculated using Bernoulli's Equation (R, Perry, 1973) and equations for estimating friction
losses. Results of these analyses (Appendix D) indicate that the WTD pump must produce approximately
60 feet of head at a 5 GPM flow rate The Grundfos 5E12 pump is capable of 5 GPM at 200 feet of
head. Recovery well, pumps and recovery well vault details are provided in Figure 5.
4.3 Oil/Water Separator
In order to comply with NPDES permitting requirements, an oil/water separator has been specified for
this facility. An AFL Industries Model VTC-5 vertical tube coalescing separator was chosen. This unit is
designed for a 5 GPM nominal flow rate. This unit utilizes a 55 gallon container for recovered product
storage. Both the oiilwater separator and the storage container will be equipped with high level
interlocks to deactivate the system upon high liquid level conditions. Based on site conditions
encountered to date, free phase product is not expected to be recovered.

4.4 Low Profile Air Stripper Design
Page 5
Results from groundwater chemical data (Table i) were used to predict the constituent levels expected in
the water pumped through the aerator. The overall compound predicted levels in the stripper influent and
effluent are as follows:
COMPOUND DESIGN INFLUENT EFFLUENT
Benzene 2,700 0.6
Ethylbenzene 1,373 0.76
Toluene 12,192 0.86
Total Xylenes 10,789 0.80
MTBE 47,302 602
Notes: All values in parts per billion (ppb)
MTBE - Methyl Teri Butyl Ether
Accordingly, the treatment unit is sized to handle a 5 GPM flow rate under nominal conditions. A low
profile air stripper will contain a total of 15 aeration chambers based on a 15 cfm per chamber air flow.
An air -to -water ratio of 337 was chosen for this application to meet the required effluent limits.
Projected air stripper effluent quality was calculated based upon the design influent concentrations noted
above. Refer to Appendix C for design calculations. Based on these results, a six feet by three feet low
profile air stripper with three stages was selected for this application. An air stripper detail sheet is
provided as Figure 8.
4.5 Air Stripper Blower Sizing
A Rotron EN 707 5 HP regenerative blower was chosen for this system. The EN 707 is capable of 240
cubic feet per minute (cfm) at 30 inches of water column (w.c.) pressure and 160 cfm at 80 inches w.c.
pressure. This would allow for a maximum air -to -water ratio of 359 and a minimum ratio of 239 for a 5
GPM flow. The manufacturers' performance curve is contained in Appendix D.

4.6 Stripper Safety Features
Page 6
The air stripper will be equipped with a blower air pressure switch which will shut down the system if air
flow stops. The stripper will also be equipped with a magnahelic pressure gauge to monitor for fouling.
The equipment will be contained in a portable building. The building will be equipped with an explosion
proof thermostat controlled heater and louvered vents for climate control. All interior electrical devices
will be specified for Class I,Division I environment.
4.7 Fouling/Dissolved Solids
Aeration of the water during air stripping will cause dissolved solids present in the groundwater to
precipitate, resulting in chamber fouling. Unless fouling proves to be excessive, it will be dealt with by
cleaning the unit periodically. The blower has been sized to accommodate a possible increase in static
pressure resulting from chamber fouling. When the internal chamber pressure reaches five to six inches of
water column pressure, the unit will be cleaned.
4. Liquid Phase Carbon Treatment
Effluent results from the low profile aerator design as noted in. Section 4.3 were used to predict the
expected concentrations in the water pumped through the (GAC) columns. The actual levels that are
found during initial system start up will be more representative of operating conditions at the site, The
expected influent and design effluent for the GAC columns are as follows:

For this site, a series of three Aquatec Model MX200-L 200 pound carbon vessels will be utilized.
Assuming hydrocarbon effluent levels from the stripper remain constant, the carbon vessels will last
approximately 88 days before changeout will be necessary. Carbon specifications are attached in
Appendix D. Effluent from the stripper will be pumped through an in line bag filter prior to the carbon
treatment units, to minimize carbon fouling. Pressure gauge fittings and sampling ports will be located at
the influent, between each vessel and at the effluent in order to monitor for fouling and break through. A
differential pressure safety interlock switch will be installed to ensure that pressure in the GAC vessels
does not become too high. This switch will deactivate the treatment system when the GAC unit pressure
reaches 10 PSI. A centrifugal transfer pump with level controls capable of 5 GPM at 10 psi will be
utilized between the low profile air stripper and the GAC columns,
4.9 Treated Water Discharge
Treated water discharge from the air stripper will pumped through GAC columns units before it is
discharged to the adjacent drainage swale in accordance with the NPDES class permit,
4.10 Piping Layout
The recovered groundwater will be pumped through a 1-1/4 inch diameter gasoline/oil rated reinforced
hose. The hose as well as two 3/4 inch diameter electrical conduits will be placed inside a six inch
diameter schedule 40 PVC chase (refer to Figure 6A). The water will be pumped into a wall mounted
oil/water separator. From the oil/water separator, the water will gravity feed to a low profile air stripper.
The water discharge from the stripper will be pumped through a series of three granular activated carbon
columns, then flow through a four -inch diameter, schedule 40 PVC line to the adjacent swale (refer to
Figure 6B). Flow control valves will be installed on each line. A flow meter will be installed on the down
stream side of the liquid carbon columns. Influent and effluent sampling ports will be installed to monitor
system efficiency.
4.11 Air Discharge
Based upon projected vapor concentrations (see Appendix B for air emission estimate) during system
operation, vapor phase treatment is proposed. Vapor phase activated carbon vessels will be utilized for
this site and discharge will be permitted through the Mecklenburg county air quality section.

Vapor effluent results from the air stripper design as noted in Section 4 3 were used to predict the
hydrocarbon concentrations expected in the vapor discharged to the GAC columns. The actual levels
that are found during initial system start up will be more representative of operating conditions at the site.
The expected concentrations in the GAC columns are as follows:

For this site, two Aquatec Model MX200-V vapor phase carbon vessels will be utilized. These vessels
will be connected in parallel and each will be capable of 150 CFM air flow rate with a pressure drop of
approximately 2.8 inches w,c, Assuming vapor hydrocarbon levels remain constant, each carbon used
will last approximately 600 days before changeout will be needed. Carbon specifications are attached in
Appendix D. Pressure gauge fittings and sampling ports will be attached on the influent and effluent of
each vessel in order to monitor for fouling and break through.
5.0 CAS OPERATION AND MAINTENANCE
The Corrective Action System (CAS) installation will begin as soon as practicable after approval of the
Corrective Action Plan, NPDES permit and air permit approval. The system startup will include an eight
hour operational test to check for piping leaks, verify flow rates and collect air and water quality samples
for analysis. Air and water quality samples will be analyzed using EPA Method 602 to calculate air
emissions and verify the performance of the treatment system. After start-up, the system will be

monitored on a weekly basis for the first month of operation and twice monthly thereafter, for the first
year of operation, This will include recording of all flow rates, water levels in all wells as well as
collection of air discharge and influent/effluent water samples. Quarterly groundwater quality samples
will be collected from monitor wells OW-1, OW-2, OW-3, OW-5 and BW-4 and analyzed by EPA
Method 602/8015 to include total xylenes and MTBE and IPE.
The site visits will include the following work tasks: periodically regulating pressure and vacuum levels,
removing debris from the blower air intake, adjusting flow rates, probe cleaning, electrical checks on the
control panel, performing any equipment repairs necessary and maintaining the physical appearance of the
compound area, Maintenance tasks will be performed during the monitoring site visits whenever
possible.
6.0 PROJECTED SYSTEM COSTS
Based on sites with similar hydrogeologic conditions and hydrocarbon impacts, the remediation is
expected to be complete in a two-year time interval following startup of the system
The estimated costs for remediation at this site are as follows:
Recovery Well Pump and Hose $3,500
Low Profile Air Stripper Including Blower and Transfer Pump 8,500

m. Adsorbers. Liquid and Vapor Phase. are available in a standard 6.5 cu.ft. capacity 55 gallon drum. These
drums adsorbers are manufactured with (16 gage) tarhon steel and are rated as 5B D.O.T, Multi -Trip Containers,
For corrosion resistance These adsorbers have an internalepoxy/phenolic and external epoxy coating.
Drum adsorbers are also available in a 57 gallon Polyethylene drum which is corrosion free and safe for most
chemicals. Since this adsorber is completely disposable the incineration costs can be reduced by more than 50 %.
ACTIVATED CARBON ABSORBERS (VAPOR)
dard Vapor Phase Activated Carbon Adsorber Fig. CI is rated at 150 CFM but can be used in higher
appiicaticans if the pressure drop is not of major concern, ' These adsorbers can be utilized in parallel service, thus
compounding their ratings. The internal distribution system consists of an upper and lower vapor plenum to prevent -
channeling and to obtain maximum bed utilization. c F t ,A
This adsorber is furnished with 6.5
cubic feet of American Norit RB3 or
RB4 Lignite Pelletized Activated
Carbon. (Lignite carbons have larger
pores and are more effective than micro -
porous carbons in high organic
concentration applications. Pelletized
carbons allow for lower pressure drops
across the carbon bed). This vessels

Aqua Ertgirreering & Suptrl , Jrrt wareirous.s a wide variety of granular and powdered 1egnatc and bituminous coal activated carbons --
many of which are dartigned for specific liquid ptuificarion objectives. Not only can Aquatec Sales Representatives help In selecting the
activated carbon that best accomplishes a p,utflcation objective, they can also recommend the most cost effective standard or custom carbon
adsorber or adsorption system.
The carbon adsorbers and adsorption systems described tend pictured in this product information sheet have been engineered to prevent
preferential flow (channeling) and allow for easy delivery and carbon changeout. Safety considerations. cost, flow rate, organic and inorganic
contaminants Lira[ their concentrations, allowable pressure drop and project length all need to be taken into consideration when selecting the
most appropriate adsorption vessel or system. Agoatac has a broad line of liquid phase activated carbon adsorbers and adsorption systems
capable of treating flow rates ranging from 1 gpm to greater than 1400 gpm - all of which can be quickly delivered, installed and serviced by
trained AQuatec technicians and engineers.
All of Aquatec's liquid adzorbers are backwashable. Standard carbon adsorbers and adsorption systettss arse sleet available with inacti-
vated carbon for a lower price and are available for lease/rent u well as for purchase. Dimensional drawings are available upon request for
any standard product. Private labeling is available.
