Dear Mr. Daniel:
Subject: Permit No. WQ0007569
Carolina Water Service, Inc, of NC
Brandywine Bay
Wastewater Spray Irrigation
Carteret County
In accordance with the amendment request received November 12, 1996, we are forwarding
herewith Permit No. WQ0007569, dated April 11, 1997, to Carolina Water Service, Inc. of NC for the
construction and operation of the subject wastewater treatment and spray irrigation facilities. This permit
is being amended to allow the construction and operation of a 50,000 GPD expansion to the existing
wastewater treatment and spray irrigation disposal system.
This permit was originally approved to allow effluent from the wastewater treatment facility to go
directly to the 5-day upset pond and then on to the effluent storage pond. The Division now recommends
that the 5-day upset pond be a separate "side -stream" pond and that all effluent go directly to the effluent
storage pond. The turbidimeter should direct all effluent which does not meet the reuse criteria to the 5-
day upset 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. The Division strongly
recommends that piping changes be undertaken at this facility to allow the effluent to bypass the 5-day
upset pond and go directly to the effluent storage pond.
Please be advised, this facility shall operate under the old buffers listed in the previous permit and
not the revised buffers in Permit Condition No. 17 until the proposed turbidimeter is installed and placed
into operation.
This permit shall be effective from the date of issuance until February 28, 1999, shall void Permit
No. WQ0007569 issued March 30, 1994, 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 15013 of the
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.

A004 DEFINITIONS
The following dallntlions shall apply throughout this Subchapler,
(1) Activated Carbon Beds. A physicaVchemical method for reducing soluble organic maletial from wastewater effiuert; The column -type beds used In this
method will have a flow rate varying from two to eight gallons per minute per square foot and may be either upflow or downflcw carbon beds. Carbon may or
may not be regenerated on the wastewater treatmerd plant she;
(2) Aerated Lagoons. A basin In which all solids are maintained In suspension and by which biological oxidation or organic matter is reduced through artificially
accelerated transfer of oxygen on a flow -through basis;
(3) Aeration. A process of bringing about intimate contact between air or high purity oxygen In a liquid by spraying, agitation or diffuslon;(3a) Extended
Aeration. An activated sludge process utilizing a minimum hydraulic detention time of 18 hours.
(4) Agricuhuraliy managed silo. Any site on which a crop is produced, managed, and harvested (Crop Includes grasses, grains, trees, etc.);
(5) Air Stripping. A process by which the ammonlum ion is first converted to dissolved ammonia (pH adjustment) with the ammor4 then released to the
atmosphere by physical means; or other similar processes which remove petroleum products such as benzene, toluene, and xylene;
(6) Carbon Regeneration. The regeneration of exhausted carbon by the use of a lumace to provide extremely high temperatures which volatilize and oxidize the
absorbed Impurities;
(7) Carbonaceous Stage, A slzge of wastewater treatment designed to achieve 'secondary' effluent Ilmhs;
(8) Centrifuge. A mechanical device In which centrifugal force Is used to separate solids from I;qulds or to separate liquids of dNfereni densMas;
(9) Chemical AddIllon Systems- The addition of chemlcal(s) to wastewater w an applicatlon point for purposes of improving solids removal, pH adjustment,
alkalinity control, etc.; the capability to experiment with CIMBrent chemicals and c0lerent application points 10 achieve a specific result will be considered one
"tam; the capability to add chemicals) to dual units will be rated as one system; capability to add a chemical at a dilfererti appllcatlon points for different
purposes will result In she systems be{ng rated as separate systems;
(10) Chemical Sludge Conditioning. The addition of a chemical compound such as time, ferric chloride, or a polymer to wet sludge to coalesce the mass prior to
its applicatlon to a dewalseng device;
(11) Closed Cycle Systems, Use of holding ponds or holding tanks for containment of wastewater oontatning Inorganic, rlcrrioxic materials from sand, gravel,
crushed stone or other similar operations. Such systems shall carry a maximum of two points regardless of pumping faclfhtes or any other appurtenances;
(12) Combined Removal of Carbonaceous 130D and Nitrogenous Removal by Nitrificatlon- A single stage system required to achieve permit effluent limits on BOO
and ammonia nitrogen within the same biological reactor,
(13) Dechforinatlon. The partia! or complete reduction of residual chlorine in a fiquld by any chemical or physical process;
(14) Denhrffication Process. The conversion of nitrate -nitrogen to nitrogen gas;
