RALEIGH
WASTEWATER TREATMENT AND RECLAIMED WATER UTILIZATION PERMIT
In accordance with the provisions of Article 21 of Chapter 143, General Statutes of North Carolina as
amended, and other applicable Laws, Rules, and Regulations
PERMISSION IS HEREBY GRANTED TO
Duplin Land Utilities, Inc.
Duplin County
FOR THE
construction and operation of a 470,000 GPD wastewater treatment and reclaimed water utilization system
consisting of a tertiary extended aeration wastewater treatment plant and disposal on an 18 hole golf course.
The wastewater treatment system consists of two phases. Phase I includes a 250,000 GPD package treatment
plant consisting of an influent flow splitter (phase I only), a manually cleaned bar screen, a 64,700 gallon
aerated equalization basin with dual 200 GPM pumps, dual 194,000 gallon extended aeration basins with
coarse bubble diffusers, dual 34,200 gallon circular clarifiers with scum baffles, an 8,000 gallon primary
disinfection tank with a chlorine treatment system, four 43.5 square foot tertiary filters with a 14,000 gallon
mud well and a 13,050 gallon clear well, a 7,800 gallon secondary disinfection tank with a UV disinfection
system, a 5,300 gallon effluent pump tank with dual 435 GPM pumps with audible and visual alarms, a 64,700
gallon aerated sludge holding tank, a 260 CFM equalization blower, three 1,000 CFM aeration blowers and a
174 CFM filter blower, an onsite emergency generator with an automatic transfer switch, a UV disinfection
automatic sampler, a turbidity monitor, flow meter, and all other necessary pipes, pumps, valves and
appurtenances for proper operation of a wastewater treatment plant. Phase I will also include a 2.35 MG lined
5 day upset pond, a 13 MG effluent storage pond, approximately 7,500 linear feet of new six inch force main
connecting to the existing pump station and 6 inch force main to transfer wastewater to the new treatment
system, approximately 14,500 linear feet of 12 inch effluent force main to discharge at the existing irrigation
pump station and modifications of the existing golf course irrigation system to allow for effluent reuse on 18
holes of the River Landing Golf Course.
Phase II consists of the construction and operation of a second a 250,000 GPD package treatment plant
identical to the plant listed in Phase I.
This facility has been approved to serve 1,236 three bedroom homes and an additional 25,000 GPD consisting
of the clubhouse and other uses for Duplin Land Utilities, River Landing Development and Golf Course with
no discharge of wastes to the surface waters, pursuant to the application received January 14, 1998 and in
conformity with the project plan, specifications, and other supporting data subsequently filed and approved by
the Department of Environment and Natural Resources and considered a part of this permit.
This permit shall be effective from the date of issuance until March 31, 2003 and shall be subject to the
following specified conditions and limitations:

r
1. PERFORMANCE STANDARDS
I. 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. If this project is to be completed inRhases and partially certified, you shall
retain the responsibility to track further construction approved under the same permit, and shall
rovide a final certificate of completion once the entire project has been complete . Mail the
Certification to the Non -Discharge Permitting Unit, P.O. Box 29535, Raleigh, NC 27626-0535.
2. The Wilmington Regional Office, telephone number 252-395-3900, shall be notified at least forty-

hours from 8:00 a.m. until 5:00 p.m. on Monday through Friday, excluding State Holidays.
The reclaimed water utilization facilities shall be effectively maintained and operated at all times
so that there is no discharge to the surface waters, nor any contamination of ground waters which
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 (Division), 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.
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 Division.
6. Diversion or bypassing of the untreated wastewater from the treatment facilities is prohibited.
7. The following buffers shall be maintained:
a) 100 feet between wetted areas and water supply wells,
b) 100 feet between wetted areas and waters classified as SA,
c) 25 feet between wetted areas and surface waters not classified as SA,
d) 100 feet between wastewater treatment units and wells,
e) 50 feet between reclaimed water storage/irrigation ponds and property lines, and
f) 50 feet between wastewater treatment units and property lines.
Public access to the irrigation sites shall be controlled during active site use. Such controls may
include the posting of signs showing the activities being conducted at each site. A sign shall be
posted in plain sight in the club house showing these activities.
11. OPERATION AND MAINTENANCE REQUIREMENTS

D004 DEFWRIONS
The following definillons shall apply throughout this Subchapter,
(1) Activated Carbon Beds. A phys;cal/chemical 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 loot and may be either upflow cr downflow carbon beds. Carbon may or
may not be regenerated on the wastewater treatment plant site;
(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 dffusion;(3a) Extended
Aeration, An activated sludge process utilizing a minimum hydraulic detention time of 18 hours.
(d) Agriculturally managed site. Any silo on which a crop is produced, managed, and harvested (Coop Includes grasses, grains, trees, etc.);
(5) Air Stripping, A process by which the ammonium ton is first converted to dissolved 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 xylem;
(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 Impurhlea;
(7) Carbonaceous Stags. A stage of wastewater treatment designed to achieve'secondary' effluent Ilmhs;
(8) Centrifuge. A mechanical device in which centrifugal force is used to separate solids from liquids or to separate liquids of [fdferent densitlas;
(9} Chemical Addition Systems- The addtilon of chemicalts)'to wastewater at an applicatlon point for purposes of Improving solids removal, pH adjustment,
alkalinity control, etc.; the capatailfty to axperlmem with dMerent chemicals and diferent application points to achieve a specific result wilt be considered one
system; the capability to add chemlcaf(s) to dual units will be rated as one system; capability to add a chemical at a different application points for different
purposes wilt result In the systems being rated as separate systems;
(10) Chemical Sludge Conditioning. The addition of a chemical compound such as lime, ferric chloride, or a polymer to wet sludge to coalesce the mass prior to
fts application to a dewatering device;
(11) Closed Cycle Systems. Use of holding ponds or hctding tanks for containment of wastewater containing Inorganic, non -toxic materials from $and, gravel,
crushed stone or other similar operations. Such systems shall carry a maximum of two points regardless of pumping faclffties or any other appurtenances;
(12) Combined Removal of Carbonaceous BOD and N'rirogencus Removal by Nitrificatlon- A single stage system required to achieve permit effluent limits on SOD
and amrnonla nitrogen within the same biological reactor,
(13) Dechforinallom The partial or complete reduction of residual cNortne In a liquid by any chemical or physical process;
(14) Donitrtficallon Process. The conversion of nhrate-nitrogen to nitrogen gas;
