WQ0006115 issued January 13, 1993, and shall be subject to the following specified conditions and
limitations:
I. PERFORMANCE STANDARDS
1. The spray irrigation 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, such as the construction of additional or replacement wastewater treatment and
disposal facilities.
2. 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.
3. 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.

4. Diversion or bypassing of the untreated wastewater from the treatment facilities is
prohibited.
5. The following buffers shall be maintained:
a) 400 feet between wetted area and any residence or places of public assembly under
separate ownership,
b) 150 feet between wetted area and property lines,
c) 100 feet between wetted area and wells,
d) 100 feet between wetted area and drainageways or surface water bodies,
e) 50 feet between wetted area and public right of ways,
f) 100 feet between treatment/storage units and any wells, and
g) 50 feet between treatment units and property lines.
Some of the buffers specified above may not have been included in previous permits for
this waste treatment and disposal system. These buffers are not intended to prohibit or
prevent modifications, which are required by the Division, to improve performance of the
existing treatment facility. These buffers do, however, apply to modifications of the
treatment and disposal facilities which are for the purpose of increasing the now that is
tributary to the facility. These buffers do apply to any expansion or modification of the
spray irrigation areas and apply in instances in which the sale of property would cause any
of the buffers now complied with, for the treatment and disposal facilities, to be violated.
The applicant is advised that any modifications to the existing facilities will require a permit
modification.
II. OPERATION AND MAINTENANCE REQUIREMENTS
1. The facilities shall be properly maintained and operated at all times.

.0004 DERNFTIONS
The following definitions shall apply throughout this Subchapler.
(1) Activated Carbon Beds. A physical/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 foot and may be either upftow or downflow carbon beds, Carbon may or
may nct be regenerated on the wastewater treatment plant silo;
(2) Aerwed 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 Inllmale contact between air or high purity oxygen In a liquid by spraying, aghallon or dlffuslon;(3a) Extended
Aeration. An activated sludge process utilizing a minimum hydraulic detention time of 16 hours -
(4) Agricuhurally managed she. Any site an 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 ammonia 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 furnace to provide extremely high temperatures which volatilize and oxidize the
absorbed Impurities;
(7) Carbonaceous Stage. A stage of wastewater treatment designed to achieve 'secondary' effluent 11mlis;
(8) Centrifuge. A mechanical device In which centrifugal force Is used to separate solids from liquids or to separate liquids of drfferent dens-cfas;
(9) Chemical Addition Systems- The addhlon of chemical(s) to wastewater at an application point for purposes of Improving solids removal, pH adjustment,
alkallnlly control, etc.; the capablihy to experiment with different chemicals and different application points to achieve a speciflc result will be considered one
system; the capability to add chemical(s) to dual units will be rated as ane system; capability to add a chemical at a different application points for different
purposes will result In the systems being rated as separate systems;
(10) Chemlcai Sludge Conditioning. The addition of a chemical compound such as Ilme, ferric chloride, or a polymer to wet sludge to coalesce the mass prior to
its application to a dewatering device;
(11) Closed Cycle Systems Use of holding ponds or holding tanks for containment of wastewater conlalning Inorganic, non-toxic materials from sand, gravel,
crushed slope or other similar operations. Such systems shall carry a maximum of two paints regardless of pumping facilities or any other appurtenances;
(12) Combined Removal of Carbonaceous BOD and Nitrogenous Removal by Nitrification- A single stage system required to achieve permit effluent limits on BOD
and ammonia nhrogen within the same biological reactor,
(13) DecNorinatiort. The partial or complete reduction of residual chlorine in a liquid by any chemical or physical process;
(14) Denitrificatlon Process. The conversion of nitrate -nitrogen 10 nitrogen gas;
