water recycling system to serve VME Sales North America, with no discharge of wastes to the surface
waters, pursuant to the application received March 1, 1994, 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 March 31, 1999, and shall be subject
to the following specified conditions and limitations:
This permit shall become voidable unless the facilities are constructed in accordance with

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. Upon completion of construction and prior to operation of this permitted facility, a.

the normal office hours from 8:00 a.m. until 5:00 p.m. on Monday through Friday,
excluding State Holidays.
8. The residuals generated from these treatment facilities must be disposed in accordance with
General Statute 143-215.1 and in a manner approved by the North Carolina Division of
Environmental Management. Therefore, the residuals generated from these treatment
facilities shall not be redeposited on-site.
9. 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.
10. 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.
11. Diversion or bypassing of untreated wastewater from the treatment facilities is prohibited.
12. Any monitoring deemed necessary by the Division of Environmental Management to insure
surface and ground water protection will be established and an acceptable sampling

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 renders the facility
incapable of adequate wastewater treatment, such as mechanical or electrical failures of
pumps, aerators, compressors, etc.;
