PERMISSION IS HEREBY GRANTED TO
Brown's of Carolina, Inc.
Duplin County
FOR THE
retrofit construction and operation of a 3,436 GPD (4,811 GPD, 5 days per week) spray irrigation
treatment and disposal facility consisting of existing dual covered truck wash bays, an existing single
stage, 42,588 ft3 lagoon, and an existing solid set irrigation system with a total of 62 sprinklers covering

to the surface waters, pursuant to the application received May 27, 1997, 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:
I. PERFORMANCE STANDARDS
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 he completed in phases
and partially certified, you shall retain the responsibility to tract further construction
approved under the same permit, and shall provide a final certificate of completion once

the normal office hours from 8:00 a.m. until 5.00 p.m. on Monday through Friday,
excluding State Holidays.

3. 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.
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.
5. 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. The land
application of the residuals generated as a result of this operation is not covered under

Standards at or beyond the Compliance Boundary is subject to immediate remediation
action in addition to the penalty provisions applicable under General Statute 143-
215.6A(a)(1).
In accordance with 15A NCAC 2L, a REVIEW BOUNDARY is established around the

1. Adequate inspection, maintenance, and cleaning shall be provided by the Permittee to
insure proper operation of the subject facilities.
2. The Permittee or his designee shall inspect the wastewater treatment and disposal

VI. GENERAL CONDITIONS
This permit shall become voidable unless the facilities are constructed in accordance with
the conditions of this permit, the approved plans and specifications, mid other supporting
data.
2. This permit is effective only with respect to the nature and volume of wastes described in
the application and other supporting data.
3. This permit is not transferable. In the event there is a desire for the facilities to change
ownership, or there is a name change of the Permittee, a formal permit request must be
submitted to the Division accompanied by an application fee, documentation from the
parties involved, and other supporting materials as may be appropriate. The approval of
this request will be considered on its merits and may or may not be approved.

.0004 DEFINfrIONS
The following definitions shall apply throughout this Subchapter.
(1) Activated Carbon Beds. A physical/chemical method for reducing soluble organic material Tram wastewater effiUera; TI•s column -type beds used in this
method will have a flow rate varying from two to eight gallons per minute per square foci and may be either upflcw or downllow carbon beds. Carbon may or
may not be regenerated on the wastewater treatment plant sits;
(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
accalaratad transfer of oxygen on a flow -through basis;
(3) Aerallom A process of bringing about intimate contact between air or high purity oxygen In a liquid by upraying, agiailon or diffuslon;(3a) Extended
Aeration. An activated sludge process utilizing a minimum hydraulic detention time of 16 hours.
(4) Agriculturally managed she. Any site on which a crop is produced, managed, and harvested (Crop includes grassas, grains, trees, etc_);
(5) Air Stripping, A process by which the ammonium Ion is first converted to dissolved ammonia (phi adjustment) w^.h tie ammonia then released to the
atmosphere by physical means; or other similar processes which remave petroleum products such as benzene, toluene, and xylene;
(6) Carbon Regeneration. The regeneratlon of exhausted carbon by the use of a lumace to provide extremely high temperatures which volatilize and axldize the
absorbed Impurities;
(7) Carbonaceous Stage. A st;tge of wastewater treatment designed to achieve 'secondary' effluent Ilmhs;
(8) Centrituge. A mechanical device In which centrtfugal farce is used to separate solids from liquids or to separate liquids of different densb:as;
(9) Chemical Addhion Systems- The addition of chemical(s) to wastewater at an application point for purposes of improving solids removal, pH adjustment,
alkalinity control, etc,; the capability to experiment with dfferent chemicals and different application points to a&ievs a specific resuft will be considered one
system; the capability to add chemiralfs) to dual units will be rated as one system; capability to add a chemical al a dfferent appilcatlon points for different
purposes will resuh in the systems being rated as separate systems;
(10) Chemical Sludge Conditioning. The addftion of a chemical compound such as lime, ferric chloride, or a polymer to wet sludge to coalesce the mass poor to
Its application to a dewatering device;
(11) Closed Cycle Systems. Use of holding ponds or Wding tanks for containment of wastewater containing inofgar.;c, non -toxic materials from Sand, gravel,
crushed stone or other similar operations. Such systems shall carry a maximum of two points regardless of purrpping laci as or any other appurtenances;
(12) Combined Removal of Carbonaceous BOO and Nlroganous Removal bry N trificaticn- A single stage system required to achieve pentO effluent limits on BOO
and ammonia nitrogen within the same biological reactor;
(13) Dechlorinatlon, The partial or complete reduction of residual chlorine In a liquid by any chemical or physical process;
(14) Dendrificatlon Process. The conversion of nitrate -nitrogen to nitrogen gas;
