Dear Mr. Daniel:
January 21, 1997
Subject: Permit No. WQ0001664
Carolina Water Service, Inc. of NC
Belvedere Plantation
Wastewater Spray Irrigation
Pender County
In accordance with your application received April 25, 1996, we are forwarding herewith Permit
No., WQ0001664, dated January 21, 1997, to Carolina Water Service, Inc. of NC for the construction
and operation of the subject wastewater treatment and spray irrigation facilities.
This permit has been limited to a maximum of I10,000 GPD because the proposed wastewater
treatment system does not have dual clarifiers sized to meet the originally proposed 150,000 GPD. One
clarifier has been sized (40,606 gallons) for the increased flow, however, the back-up clarifier is only
10,000 gallons therefore the wastewater treatment capacity shall remain at 110,000 GPD until the permit
has been amended and plans submitted to increase the volume of the clarifier.
The existing Division of Environmental Health (DEH) subsurface system was not considered part
of the review of the proposed spray irrigation system. Issuance of this permit does not authorize operation
of the existing subsurface permit. If Carolina Water Service, Inc. of NC would like to maintain the
existing subsurface system as a back-up to the proposed system, it will be the company's responsibility to
maintain that subsurface disposal permit through DEH.
This permit shall be effective from the date of issuance until December 31, 2001, 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 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.

subject to the following specified conditions and limitations:
I. PERFORMANCE STANDARDS
Upon completion of construction and prior to operation of this permitted facility, a
certification must be received from a professional engineer certifying that the permitted
facility has been installed in accordance with this permit, the approved plans and
specifications, and other supporting materials. Mail the Certification to the Water Quality
Permits and Engineering Unit, P.O. Box 29535, Raleigh, NC 27626-0535.

will render them unsatisfactory for normal use. In the event that the facilities fail to
perform satisfactorily, including the creation of nuisance conditions or failure of the
irrigation area to adequately assimilate the wastewater, the Permittee shall take immediate
corrective actions including those actions that may be required by the Division of Water
Quality, such as the construction of additional or replacement wastewater treatment and
disposal facilities.
4. The issuance of this permit shall not relieve the Permittee of the responsibility for damages
to surface or groundwaters resulting from the operation of this facility.
5. The residuals generated from these treatment facilities must be disposed in accordance with
General Statute 143-215.1 and in a manner approved by the North Carolina Division of
Water Quality.

of Title 15A, Chapter 8A, .0202. The ORC of the facility must visit each Class I facility at
least weekly and each Class II, III, and IV facility at least daily, excluding weekends and
holidays, and must properly manage and document daily operation and maintenance of the
facility and must comply with all other conditions of Title 15A, Chapter 8A, .0202. Once
the facility is classified, the Permittee must submit a Ietter to the Certification Commission
which designates the operator in responsible charge within thirty days after the wastewater
treatment facilities are 50% complete.
3. A suitable vegetative cover shall be maintained on the spray irrigation areas
2
4. Irrigation shall not be performed during inclement weather or when the ground is in a
condition that will cause runoff.
5. Adequate measures shall be taken to prevent wastewater runoff from the spray field.

8. No type of wastewater other than that from Belvedere Plantation shall be sprayed onto the
irrigation area.
9. All wastewater shall be routed to the five-day holding tank should the limit for fecal
coliform (daily maximum concentration of 25 per 100 ml) or turbidity (instantaneous
maximum of 10 NTU) be exceeded, until such time that the problems associated with the

d. Any time that self -monitoring information indicates that the facility has gone out of
compliance with its permit limitations.
Persons reporting such occurrences by telephone shall also file a written report in letter
form within five (5) days following first knowledge of the occurrence. This report must

DM4 DEFLNMONS
The following delWlions shall appfy throughout this Subchapter.
(1) Activated Carbon Eads. A physlcallchemical method for reducing soluble organic material from wastewater effluent; 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 upfiow or downflow carbon beds. Carbon may or
may not be regener;ced on the wastewater traatmer7 plant site;
(2) Aerated Lagoons A basin in which all solids are maintained In suspension and by which biolcgfcaf oxidation or organic matter Is reduced through artificially
accelerated transfer of oxygen on a flow -through basis;
(3) Asratlon. A process of bringing about Intimate contact between air or high purity oxygen in a [lquid by spraying, aghatfon or dlffuslon;(3a) Extended
Aeration. An activated sludge process utilizing a minimum hydraulic detention time of 16 hours-
(4) Agricuhuraily managed site. Any site on which a crop is produced, managed, and harvested (Crop Includes grassas, grains, trees, etc.);
(5) Air Slrpping. A process by which the ammonium ion is first converted to dfssofved ammonia (pH adjustment) with the ammonia then released to the
atmosphere by physical means; or other similar processes which remove petroleum products such as benzene, toluene, and xylere;
(6) Carbon Regeneration. The regeneration of exhausted carbon by the use of a furnace to provide extremely high temperatures which volatilize and oxidize the
absorbed impurttlea-
(7) Carbonaceous Stage. A stage of wastewater treatment designed to achieve 'secondary' effluent Umits;
(8) Centrifuge. A ma&.anicaJ device In which csntrfugai force is used to separate solids from liquids or to separate liquids of d'fereni densc;as;
(9) Chemlczi Addition Systems- The add'ilon of chemica!fs) to wastewater at an appilcat!on point for purposes of improving solids removal, pH adjustment.
alkalinity control, etc-; the capabllffy to experiment with dtarern chemicals and dtferem application points to achieve a specific resuh will be considared one
system; the capability to add chamicaf(s) to dual units will be rated as one system; Capability to add a chemical at a dilterer:t appllcation points for different
purposes will result in the systems being rated as separate systems;
(10) Chotm!al Sludge Condltloning, The addition of a charnical compound such as time, ferric chloride, or a polymer to wet sludge to coalesce the mass pr"or to
Its application to a dewatering device;
(11) C!osad Cycle Systems Use of holding ponds or hcldng tanks for contafnment of wastewaler containing Inorganic, non -toxic materials from sand, gravel,
crushed store or other similar oper colons. Such systems shall carry a maximum of two points regardless of pumping facilifies or any other appurtanancus;
(12) Combined Removal of Carbonaceous 600 and Nerogerous Removal by NriHicalfonr A single stage system required to achieve pemmt elfluer4 1'vnits on BCD
and ammonia nitrogen within the same biological reactor,
(13) Dechlornallort The partial or complete reduction of residual chlorine In a liquid try any chemical or physical process;
(14) Denhritiration Process. The conversion of nhra:a-nrrcrnn in niirnnnn mac
