effectively disperse the volume of water generated by the recovery wells pumping at the maximum rates.
This permit shall be effective from the date of issuance until November 30, 2000, shall void Permit
No. WQ0004097 issued May 20, 1991, and shall be subject to the conditions and limitations as specified
therein. Please pay particular attention to the monitoring requirements in this permit. Failure to establish
an adequate system for collecting and maintaining the required operational information will result in future
compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the
right to request an adjudicatory hearing upon written request within thirty (30) days following receipt of
this permit. This request must be in the form of a written petition, conforming to Chapter 150B of the
North Carolina General Statutes, and filed with the Office of Administrative Hearings, P.O. Drawer
