Dear Mr. Hager:
The Division of Environmental Management is in receipt of information which
confirms that the subject facility does not discharge to the surface waters of the
State of North Carolina.
Due to this fact there is no need for this facility to have a NPDES permit.
Therefore, based on your request, NPDES Permit No. NC0004537 is hereby rescinded
effective immediately. Should you wish at some future time to discharge to the
surface waters, it will require the issuance of a new discharge permit.
If you have any questions regarding this matter, please contact Mr. Arthur
