million gallons, and approximately 88.5 acres of spray irrigation fields.
The above facilities will serve the Town of Surf City, with no discharge of wastes to the surface waters, pursuant to
the renewal request received February 6, 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 April 30, 2003, shall void Permit No.
WQ0000795 issued September 24, 1993, and shall be subject to the following specified conditions and limitations:
I. PERFORMANCE STANDARDS
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 (Division), 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.
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.
4. Diversion or bypassing of the untreated wastewater from the treatment facilities is prohibited.
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 wastewater treatment units and wells, and
g) 50 feet between wastewater 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 flow 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.

The fo%owing definitions shall apply throughout this Subchapter,
(1) Ac%rvated Carbon Beds. A physicavchemicai method tot reducing soluble organic material from wastewater ettluenc, The column -type beds used ;n this
method wi'I have a flow rase varying from two to eight gallons per minute per square tool and may be ehhsr upilow or downflow carbon beds. Garton may or
may not be regenerated on the wastewater treatment plant she;
(2) Aerated Lagoons. A basin in which all solids are mainlained in suspension and by which biological oxidation or organic maner Is reduced through artificially
accelerated transfer of oxygen on a flow-through basis;
(3) Aeration. A process of bHnging about intimate contact between air or high purtty oxygen in a liquid by spraying, agitation or dfffuslon;(3a) Extended
Aeration. A� activated 61udge process utilizing a minimum hydraulic detention time.of 18 hours.
(4) A,gricuhurally managed she. Any she on which a crop Is produced, managed, and harvaslad (Crop includes grasses, grains, trees, plc.);
(5) Air Stripping. A process by which the ammonium Ion is first convened to dissolved ammonia (pH adjustment) whir the ammonia then releasad to the
atmosphere by physical means; or other similar processes which remove petroleum products such as benzene, toluene, and xylene;
(6) Carbon Fsegeneratlom The regeneration of exhausted carbon by the use of a furnace to provide extremely high temperatures which volatilize and oxidize the
absorbed impurities;
