Subject: Permit Renewal and Minor Modification
Permit No. WQ0019336
Town of Carolina Beach
Conjunctive Use
Reclaimed Water Utilization System
New Hanover County
In accordance with your application received October 28, 2005, we are forwarding herewith Permit No.
WQ0019336, dated June 22, 2006, to The Town of Carolina Beach for the operation of the subject wastewater treatment
reclaimed water utilization system.
This permit shall be effective from the date of issuance until May 31, 2011 and shall be subject to the conditions
and limitations as specified therein. Please also 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.
As per your request, the reissued permit incorporates the town's new chlorination system and removes the
requirement for daily Total Settleable Solids monitoring. You should also note that a new daily monitoring condition has
been added for Residual Chlorine due to the addition of the chlorination system.
Please also note that condition VI.9. of this permit requires the town to request modification of its NPDES Permit
(NCO023256) to allow the conjunctive use of reclaimed water. Since your NPDES permit is scheduled to expire on
December 31, 2006, you should request this modification as part of that permit renewal. This renewal request is due to
the Division of Water Quality by no later than July 1, 2006.
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 fled 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.
