William G. Ross Jr., Secretary
North Carolina Department of Environment and Natural Resources
Alan W. Klimek, P-E. Director
Division of Water Quality
Subject: Permit No. WQ0002428
Townsend Farms Hatchery
Wastewater Surface Irrigation
Chatham County
In accordance with your permit renewal and modification request to increase application rates and
decrease application area received March 10, 2005, and subsequent additional information received
February 27, 2006, May 23, 2006, September 18, 2006, and September 27, 2006, we are forwarding
herewith Permit No. WQ0002428 dated November 21, 2006, to Townsend Farms, Inc. for the continued
operation of the subject wastewater treatment and surface irrigation facilities.
This permit shall be effective from the date of issuance until October 31, 2011, shall void Permit
No, WQ0002428 issued March 19, 2003, 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.
This permit approves the continued operation of the subject wastewater treatment and spray
irrigation facilities for another five-year cycle. However, please take the time to review this permit
thoroughly as some of the conditions contained therein may have been added or changed since the last
issuance of this permit. Of special interest are the following:
• Condition 111.2 — Note that an influent flow meter shall be installed when daily flows
exceed sixty percent (60%) of the permitted flow (i.e. approximately 15,000 GPD).
In addition to the installation of the influent flow meter when daily flows exceed 15,000 GPD, the
permittee shall evaluate storage at the treatment facility. The Division of Water Quality has determined
that the storage of the facility is inadequate for daily flows exceeding 15,000 GPD. At influent flows
exceeding this value, the facility approaches a critical point where the system could not accept any more
waste without the possibility of overflows.
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, 6714 Mail Service
Center, Raleigh, NC 27699-6714. Unless such demands are made this permit shall be final and binding.
