Guilford County
FOR THE
operation of an existing 2,700 GPD wastewater recycle system consisting of a building enclosed truck

gallon) with a sump pump, a 250 gallon coalescing oil/water separator, a 100 gallon emulsified
oil/water/solids separator, a 500 gallon treated water storage tank with an ozone generator, a return pump,
and all associated piping, valves, controls, and appurtenances to serve Overnite Transportation Company's
Greensboro Terminal Truck Wash with no discharge of wastes to the surface waters, pursuant to the
application received February 5, 1993, and in conformity with the project plan, specifications, and other
supporting data subsequently filed and approved by the Department of Environment, Health and Natural
Resources and considered a part of this permit.
This permit shall be effective from the date of issuance until February 28, 1998, and shall be
subject to the following specified conditions and limitations:
I . This permit shall become voidable unless the facilities are constructed in accordance with
the conditions of this permit, the approved plans, specifications, and other supporting data.
2. This permit is effective only with respect to the nature and volume of wastes described in
the application and other supporting data.
3. The facilities shall be properly maintained and operated at all times.
4. This permit is not transferable. In the event there is a desire for the facilities to change
ownership, or there is a name change of the Permittee, a formal permit request must be
submitted to the Division of Environmental Management accompanied by an application
fee, documentation from the parties involved, and other supporting materials as may be
appropriate. The approval of the request will be considered on its merits and may or may
not be approved.
5. In the event that the facilities fail to perform satisfactorily, including the creation of
nuisance conditions, the Permittee shall take immediate corrective action, including those as
may be required by this Division, such as the construction of additional or replacement
wastewater treatment or disposal facilities.

6. The sludge generated from these treatment facilities must be disposed of in accordance with
General Statute 143-215.1 and in a manner approved by the North Carolina Division of
Environmental Management.
7. The issuance of this permit shall not relieve the Permittee of the responsibility for damages
to surface or groundwaters resulting from the operation of this facility.
8. The facilities shall be effectively maintained and operated as a non -discharge system to
prevent the discharge of any wastewater resulting from the operation of this facility.
9. Diversion or bypassing of untreated wastewater from the treatment facilities is prohibited.
10. Any monitoring deemed necessary by the Division of Environmental Management to insure
surface and ground water protection will be established and an acceptable sampling
reporting schedule shall be followed.
11. Adequate inspection, maintenance, and cleaning shall be provided by the Permittee to
insure proper operation of the subject facilities.
12. The Permittee or his designee shall inspect the wastewater recycle facilities to prevent
malfunctions and deterioration, operator errors and discharges which may cause or lead to
the release of wastes to the environment, a threat to human health, or a nuisance. The
Permittee shall keep 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 upon request to
the Division of Environmental Management or other permitting authority.
13. Any duly authorized officer, employee, or representative of the Division of Environmental
Management may, upon presentation of credentials, enter and inspect any property,
premises or place on or related to the recycle system at any reasonable time for the purpose
of determining compliance with this permit; may inspect or copy any records that must be
kept under the terms and conditions of this permit; or may obtain samples of groundwater,
surface water, or leachate.
14. The annual administering and compliance fee must be paid by the Permittee within thirty

Permittee to an enforcement action by the Division of Environmental Management in
accordance with North Carolina General Statute 143-215.6A to 143-215.6C.

Permittee for the life of this project.
18. A record shall be maintained of all residuals removed from this facility. This record shall

municipality agreeing to accept the residuals, date the residuals were hauled, and volume of
residuals removed. This report shall be furnished to the Division's Winston-Salem
Regional Office for each calender year by January 31st of the year following the disposals.
2

The Permittee shall report by telephone to the Winston-Salem Regional Office, telephone
number 919/ 896-7007 as soon as possible, but in no case more than 24 hours or on the
next working day following the occurrence or first knowledge of the occurrence of any of

significant amounts of wastes which are abnormal in quantity or characteristic, such
as the dumping of the contents of a basin or tank; the known passage of a slug of
hazardous substance through the facility; or any other unusual circumstances.
b. Any process unit failure, due to known or unknown reasons, that render the facility
incapable of adequate wastewater treatment such as mechanical or electrical failures
of pumps, aerators, compressors, etc.
c . Any failure of a pumping station, sewer line, or treatment facility resulting in a by-
pass directly to receiving waters without treatment of all or any portion of the
influent to such station or facility.
d. Any time that self -monitoring information indicates that the facility is not in
compliance with its permit limitations.
Persons reporting such occurrences by telephone shall also file a written report in letter
form within 15 days following first knowledge of the occurrence. This report must outline
the actions taken or proposed to be taken to ensure that the problem does not recur.
20. A leakage test shall be performed on the sump tank, oil/water separator tanks and dosing
tank to insure that there are no discharges or leaks. The test results information shall be
reported to the Winston-Salem Regional Office.
21. Upon classification of the facility by the Certification Commission, the Permittee shall
employ a certified wastewater treatment plant operator to be in responsible charge (ORC) of
the wastewater treatment facilities. The operator must hold a certificate of the type and
grade at least equivalent to or greater than the classification assigned to the wastewater
