In accordance with the provisions of Article 21 of Chapter 143, General Statutes of North Carolina as amended,
and other applicable Laws, Rules, and Regulations
PERMISSION IS HEREBY GRANTED TO
Comer Oil Company
Edgecombe County
FOR THE
continued operation of a 2880 GPD groundwater remediation facility consisting of a recovery well, air stripper,
sump collection tank with a 2 GPM sump pump, dual particulate filters in series (25 micron followed by a 10
micron), dual activated carbon filters in series, and two 50'x2'x2.5' infiltration galleries, and all associated
valves, pumps, pipes and appurtenances, to remediate gasoline contamination with no discharge of wastes to the
surface waters, pursuant to the application received February 15, 2009, and in conformity with the project plan,
specifications, and other supporting data filed and approved by the Division and considered a part of this permit.
This permit shall be effective from the date of issuance until March 31, 2014, shall void Permit No. WQ0014508
issued December 10, 2004, and shall be subject to the following specified conditions and limitations:
I. PERFORMANCE STANDARDS
The groundwater treatment system shall consistently achieve at least 95% removal of the influent
contaminants or 15A NCAC 2L Section .0202(g) Class GA Standards (whichever is higher) prior to
discharge to the infiltration galleries. The treated water discharged into the infiltration galleries must not
cause a violation of Class GA Standards for any constituent beyond the Compliance Boundary, nor cause
the migration of the contamination into unaffected areas. If the treatment system fails to consistently
achieve this standard, additional treatment units or changes in operational needs may be required.
2. This permit shall become voidable if the soils fail to adequately assimilate the remaining wastes and may
be rescinded unless the facilities are installed, maintained, and operated in a manner, which will protect
the assigned water quality standards of the surface and ground waters.
3. The issuance of this permit shall not relieve the Permittee of the responsibility for damages to surface or
ground waters resulting from the operation of this facility.
4. Any residuals generated from these treatment facilities must be disposed in accordance with General
Statute 143-215.1 and in a manner approved by the Division.
5. Diversion or bypassing of the untreated groundwater from the treatment facilities is prohibited.

discharge of any wastewater resulting from the operation of this facility. The groundwater recovery,
treatment and disposal system shall be inspected weekly. If it is determined that the system is
malfunctioning or leading to the release of wastes to the environment, a threat to human health, or a
nuisance, all repairs should be made as soon as possible and reported to the Raleigh Regional Office (see
Section V. NONCOMPLIANCE NOTIFICATION). All components of the groundwater recovery,
treatment, and disposal system shall be properly weatherproofed to prevent freezing and failure of the
system.
2. Upon classification of the wastewater treatment and remediation facilities by the Water Pollution. Control
System Operators Certification Commission (WPCSOCC), the Permittee shall designate and employ a
certified operator to be in responsible charge (ORC) and one or more certified operator(s) to be back-up

conditions specified in these rules.

5. The Permittee shall maintain an inspection log or summary including at least the date and time of
inspection, observations made, and any maintenance, repairs, or corrective actions taken by the Permittee.
This log of inspections shall be maintained by the Permittee for a period of three years from the date of
the inspection and shall be made available to the Division or other permitting authority, upon request.
6. Any duly authorized officer, employee, or representative of the Division may, upon presentation of
credentials, enter and inspect any property, premises or place on or related to the disposal site or facility at
any reasonable time for the purpose of determining compliance with this permit, may inspect or copy any

3. Prior to sampling the parameters, the measurement of water levels must be taken. The depth to water in
each well shall be measured from the surveyed point on the top of the casing. The measuring points (top
of well casing) of all monitoring wells shall be surveyed relative to a common datum.
