Subject: Permit No. WQ0007569
Carolina Water Service, Inc. of NC
Brandywine Bay
Wastewater Treatment and Spray
Irrigation of Reuse -Quality Effluent
Carteret County
In accordance with your modification request received January 25, 1999 and the supplemental material
received June 2, 1999, we are forwarding herewith Permit No. WQ0007569, dated September 17, 1999, to
Carolina Water Service, Inc. of NC for the specified construction and continued operation of the subject
wastewater treatment and spray irrigation facilities.
This permit was originally approved to allow effluent from the wastewater treatment facility to go
directly to the five-day holding pond and then on to the effluent storage pond. In Permit No. WQ0007569
issued October 29, 1998, the Division recommended that the five-day holding pond be a separate "side -stream"
pond and that all effluent go directly to the effluent storage pond. This permit modification allows the
Permitter, to install piping and structures in the existing system so that the five-day holding pond is isolated for
use only during treatment upsets. This modification includes: plugging the existing overflow line from the
five-day holding pond to the 3.35-acre storage and infiltration pond, installing a slide gate at the existing outlet
pipe of the five-day holding pond, installing a pump and piping system that can return the contents of the five-
day holding pond to the headworks of the wastewater treatment plant, and installing a discharge line from the
wastewater treatment plant to the 3.35-acre storage and infiltration pond. This permit modification also allows
the construction of an overflow structure that will divert treated effluent from the existing storage and
infiltration pond to the irrigation pond.
Please be aware of Condition 1113 which states, "A telemetry system must be installed within 60 days
of permit issuance that will notify the ORC in the event that turbidity limits are exceeded." Also please note
Condition H 14 which states, "A continuous monitoring turbidimeter must be installed and operating within 60
days of permit issuance." The turbidimeter should direct all effluent which does not meet the reuse criteria to
the five-day holding pond until the treatment facility has been corrected. Once corrected, the effluent in the 5-
day pond should then be rerouted to the wastewater treatment facility for retreatment. Please be advised, this
facility shall operate in compliance with the buffers listed in Condition 17 and not the revised buffers in
Condition 18 until the proposed turbidimeter is installed and placed into operation.

In addition, please be aware of Condition II 15 which states, "The slide gate located in the five-day
holding pond shall remain closed at all times unless otherwise approved by the Wilmington Regional Office."
And, Condition lI 16 which states, "The overflow line leading from the five-day holding pond to the storage
and infiltration pond shall remain plugged at all times."
This permit shall be effective from the date of issuance until September 30, 2003, shall void Permit
No. WQ0007569 issued October 29, 1998, 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 filcd with the Office of Administrative Hearings, 6700 Mail Service Center, Raleigh, NC
27699-6700. Unless such demands are made this permit shall be final and binding.
One set of approved plans and specifications is being forwarded to you. If you need additional
information concerning this matter, please contact Ms. Joni Cardin at (919) V3-5083 extension 509.
