Town of Fair Bluff
Land Application of Wastewater Residuals
Columbus County
Dear Mayor Evans:
In accordance with your application received on June 1. 1994, we are forwarding herewith Permit
IVo. WQ0001935 dated September 30, 1994, to the Town of Fair Bluff for the continued operation of a
wastewater residuals land application program. Under penalty of law on both Federal and State levels, the
land application of residuals requires the stabilization of said permitted residuals to meet pathogen and
vector attraction requirements as stated in 40 CFR, Part 503. This permit contains conditions that require
the complete stabilization of the subject residuals prior to land application. It is understood the Town of
Fair Bluff will meet pathogen and vector attraction requirements using lime to raise the pH to 12 and
holding it there the required times as stated in 40 CFR Part 503, with a tanker track being used for mixing
and storage.
This permit shall be effective from the date of issuance until August 31, 1999, and shall be subject
to the conditions and limitations as specified therein. Please pay particular attention to the monitoring and
reporting requirements contained in this permit. Failure to establish an adequate system for collecting and
maintaining the required operational information will result in future compliance problems. Issuance of this
permit hereby voids Permit No. WQ0001935 issued October 13, 1989.
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 North
Carolina General Statutes, and filed with the Office of Administrative Hearings, P.O. Drawer 27447.
Raleigh, NC 27611-7447. Unless such demands are made this permit shall be final and binding.
