Hunt, Jr., Governor Jonathan B. Howes, Secretary p C H N A. Preston Howard, Jr., P.E., Director Carl Daniel, Vice President Carolina Water Service, Inc. of NC Post Office Box 240705 Charlotte, North Carolina 28224 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. P.O.

BB -Up Points ------------------------------------------------------------- Facilities having a rating of one through four points, Inclusive, do not require a certified operator. Facilities haying an -az,vaad sludge process will be assigned a minimum classification of C:aass IL Facilities having treatment processes for the removal of metal or cyanide wilf be assigned a minimum classification of Class U. Facilities having trearrnenrt processes for the biological removal of phosphorus will be assigned a minimum classification of Class 111. 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
