FOR THE
continued operation of an 800,000 GPD spray irrigation treatment and disposal facility. This facility
consists of a 775 GPM influent pump station with dual pumps, a wedgewire screening unit, a 500 square
foot dissolved air flotation unit, two stabilization lagoons (one 7.755 million gallons and another 8.175
million gallons capacity) in series, a 950 GPM transfer pump station with dual pumps and liquid chlorine
feed system, a 35 million gallon storage lagoon (63 days storage capacity), 2,000 GPD irrigation pump
station with dual pumps, and approximately 147 acres of irrigation fields and 41 additional acres used only
for crop maintenance to serve House of Raeford, Inc., with no discharge of wastes to the surface waters.
Issuance of this permit is pursuant to the application received September 21, 1994, and in conformity with
the project plan, specifications, and other supporting data subsequently filed and approved by the
Department of Environment, Health and Natural Resources and considered a part of this permit.
This permit shall be effective from the date of issuance until October 31, 1999, and shall be subject
to the following specified conditions and limitations:
I. PER_FQRMANCE 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
Environmental Management, 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
Environmental Management.

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 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.
6. The sludge in the two stabilization lagoons shall be removed to a depth sufficient to provide
a minimum capacity of 7.755 million gallons in the first lagoon and 8.175 million gallons
in the second. The solids shall be disposed of on the site approved in Permit No.
WQ0001481 issued July 29, 1994.
7. The 13.1 acre reserve area included on sheet 17A of the approved plans shall be maintained
for the life of the permit.
H. OPERATION AND MAINTENANCE REQ111REMENTS
1. The facilities shall be properly maintained and operated at all times.
2. Upon classification of the facility by the Certification Commission, the Permittee shall
employ a certified wastewater treatment plant operator to be in responsible charge (ORC) of

ZC04 DEFINII DONS
The following definitions shall apply throughout this Subchaptar.
(1) Activated Carbon Bads. A physical/chemical method for reducing soluble organic material from wastewater effluent; The column -type beds used in this
method will have it flow two varying from two to eight gallons per minute per square Soot and may be shher upffow or downitow carbon beds. Carbon may or
may not be regenerated on the wastawater treatment plant she;
(2} Aerated Lagoons. A basin in which all solids are maintained In suspension and by which biological oxidation or organic matter Is reduced through arlificialty
n lerated transfer of oxygen on a flow -through basis;
(3) Aeration. A process of bringing about fntlmate contact between al. or high purity oxygen in a liquid by spraying, agitation or dlffuslon:(3a) Extended
Aerafion. An activated sludge process utilizing a minimum hydraulic detention time of 16 hours.
(4) Agricuhurally managed site. Any site on which a crop Is produced, managed, and harvested (Crop Includes grasses, grains, trees, etc.);
(5) Air Stripping. A process by which the ammonium tort Is first corr✓erted to dissolved anunonia (pH adjustment) with the ammonia than released to the
atmosphere by physical means; or other similar processes which remove petroleum prodvcts such as benzene, toluene, and xylone;
(6) Carbon Regeneratlon. 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 achleve 'secondary, effluent limits;
(8) Centrifuge. A mechanical device in which centrtfugal force Is used to separate solids Irom €tqulds or to separate hqulds of c9fforent dansr,ias;
