General 1 ermit Coverage. In accordance with your application to discharge treated groundwater
contaminated with fuel hydrocarbons, the Division of Water Resources (DWR or the Division) hereby
forwards this Certificate of Coverage (COC) to discharge under the subject NPDES general permit.
We issue this COC pursuant to the requirements of NorthCarolina General Statue 143-215.1 and the
Memorandum of Agreement between North Carolina and the US Environmental Protection Agency
(USEPA) dat=t October 15, 2007 (or as subsequently amended).
The following information is included with your permit package:
• A copy of the Certificate of Coverage for your treatment facility
• A copy of General Wastewater Discharge Permit NCG510000
• A copy of a Technical Bulletin for General Wastewater Discharge Permit NCG510000
• Engineer's Certification, to be signed and returned to DWR upon completion
The Division understands from your Notice of Intent (NOI) received September 12, 2017 that you
your site-remediation Corrective Action Plan (CAP) was approved August 11, 2016 by the
NCDEQ Division of Waste Management UST Section, Mooresville Regional Office.
Future reporting under this COC shall compare all analytical results to Surface Water -Quality
Standards appropriate to a receiving -stream classified. C. We note that site -assessment analytical data
(April 05, 2017) suggests that combined gasoline and kerosene, appear to be the sources of site
contamination, and that chlorinated solvents may not be a problem in the subsurface. If additional
chlorinated solvents are detected in the future, you must apply immediately for an individual NPDES
permit.
Based on the above, the General Permit's effluent monitoring Table A. (3.) applies to your facility as
having been impacted by sources of combined gasoline and diesel fuel with a design discharge flow
rate of 1,296 gpd (<0.05 MGD). Monitoring Tables A. (1.), A. (2.), A. (4.), A. (5.) and A. (6.) do not
apply.

At no time shall treatment -system operators allow contaminated (untreated) water to discharge to
surface waters of the State. At no time shall treated water discharge such that sediment is
transported and/or erosion occurs. The Measurement Frequency "Monthly Flow" is defined as total
treated effluent not -to -exceed one million gallons (1.0 MG) per month. This assumes that the
system utilizes a totalizing flow meter (or equivalent method) to determine and record total flow,
and report this value on quarterly Discharge Monitoring Reports (DMRs).
In accordance with your application for discharge and Corrective Action Plan (CAP), the Division
understands you propose to construct and operate a groundwater remediation system consisting of:
• Groundwater Recovery Wells.
• An Oil/Water separator (155 gallon) with a rated flow capacity of 20 gpm, detention time of
7.75 min and a free product disposal method that utilizes a gravity drain to an external 500-
gallon AST.
• An air stripper with four (4) trays, a rate 50 gpm, air max @400 cfin; air -to -water ratio 8:1
(cfm/cfm) (99.9% removal efficiency)
• Two (2) bag filters in series; 100 gpm.
• Two (2) carbon adsorption drums; rate 40 gpm; in series; each 200-lbs; carbon breakthrough
time: first unit time is 84 months based on calculation with an anticipated 0.9 gpm
continuous flow rate.
• Effluent discharge line with flow meter.
• Discharge outfall.
The above treatment works, Located at Speedway 7971 (Former WilcoHess 351) located at 1343 Rock
Barn Rd NE, Conover 28613-7565, will be installed and operated in accord with your discharge
application, Notice of Intent (NOI), and as described on your schematic and site plan. Treated
groundwater shall discharge under receiving stream zero -flow conditions (7Q10 and 30Q2 = 0.0 cfs)
ultimately to an unnamed tributary (UT) to Mahaffie [Stream Segment 11-76-2], a waterbody
currently classified C within Subbasin 03-08-32 [HUC: 030501011102] of the Catawba River Basin,
as documented on the attached Site Map.
In the event that treatment facilities fail to perform satisfactorily, to include creating nuisance
conditions, the Permittee shall take immediate corrective action, including those actions as may be
required by this Division, such as the construction of additional or replacement wastewater treatment
or disposal facilities. Failure to abide by the requirements contained in this ATC may subject the
Permittee to an enforcement action by the Division of Water Resources in accordance with North
Carolina General Statute I43-215.6A to 143-215.6C.
Please notify Corey Basinger of the Division's Mooresville Regional Office (MRO) by telephone 704-
663-1699 at least three (3) working days in advance of operating the treatment -system so that he may
determine the need for final inspection requirements. Please contact MRO during the normal office
hours from 8:00 a.m. until 5:00 p.m. Monday through Friday, excluding State Holidays.
NPDES Permit Contact. If you have questions concerning the requirements of this permit, please
contact the MRO or Derek Denard of the NPDES Unit, Raleigh at 919-807-6307.

If any parts, measurement frequencies or sampling requirements contained in this general permit are
unacceptable, you have the right to request an individual permit by submitting an individual NPDES
permit application. Unless such demand is made, the certificate of coverage shall be final and binding.
Please note that this permit is not transferable except after notice to the Division. The Division may
require modification or revocation and reissuance of the permit. This permit does not affect the legal
requirements to obtain other permits which may be required by the Division of Water Resources or
any other Federal, State, or Local governmental permits that may be required.
