specifications, and other supporting materials. Mail the Certification to the Water Quality
Permits and Engineering Unit, P.O. Box 29535, Raleigh, NC 27626-0535.

6. In the event that the facilities fail to perform satisfactorily, including the creation of
nuisance conditions, the Permittee shall take immediate corrective action, including those
actions that may be required by this Division, such as the construction of additional or
replacement treatment or disposal facilities.
7. The Raleigh Regional Office, telephone number 9191 571-4700 shall be notified at least
forty-eight (48) hours in advance of operation of the installed facilities so that an in-place
inspection can be made. Such notification to the regional supervisor shall be made during
the normal office hours from 8:00 a.m, until 5:00 p.m. on Monday through Friday,
excluding State Holidays.
8. 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.
9. 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.
10. The facilities shall be effectively maintained and operated as a non -discharge system to
prevent the discharge of any wastewater resulting from the operation of this facility.
It. Diversion or bypassing of untreated wastewater from the treatment facilities is prohibited.
12. Any monitoring deemed necessary by the Division of Environmental Management to insure
surface and ground water protection will be established and an acceptable sampling
reporting schedule shall be followed.
13. Adequate inspection, maintenance, and cleaning shall be provided by the Permittee to
insure proper operation of the subject facilities.
14. The Permittee or his designee shall inspect the wastewater recycle facilities to prevent
malfunctions and deterioration, operator errors and discharges which may cause or lead to

Permittee shall maintain an inspection log or summary including at least the date and time of
inspection, observations made, and any maintenance, repairs, or corrective actions taken by
the Permittee. This log of inspections shall be maintained by the Permittee for a period of
three years from the date of the inspection and shall be made available to the Division of
Environmental Management or other permitting authority, upon request.

Management may, upon presentation of credentials, enter and inspect any property,
premises or place on or related to the recycle system at any reasonable time for the purpose
of determining compliance with this permit, may inspect or copy any records that must be
maintained under the terms and conditions of this permit, and may obtain samples of
groundwater, surface water, or leachate.
16. The annual administering and compliance fee must be paid by the Permittee within thirty
(30) days after being billed by the Division. Failure to pay the fee accordingly may cause
the Division to initiate action to revoke this permit as specified by 15A NCAC 2H .0205

a. Any occurrence at the wastewater treatment facility which results in the treatment of
significant amounts of wastes which are abnormal in quantity or characteristic, such as
the dumping of the contents of a basin or tank, the known passage of a slug of
hazardous substance through the facility, or any other unusual circumstances;
b. Any process unit failure, due to known or unknown reasons, that renders the facility
incapable of adequate wastewater treatment, such as mechanical or electrical failures of
pumps, aerators, compressors, etc.;
c. Any failure of a pumping station, sewer line, or treatment facility resulting in a by-pass
directly to receiving waters without treatment of all or any portion of the influent to
such station or facility; or
d. Any time that self-monitoring information indicates that the facility is not in compliance
with its permit limitations.
Persons reporting such occurrences by telephone shall also file a written report in letter

.0074 DEFINITIONS
The following definitions shall apply throughoul this Subchapler,
(1) Activaled Carbon Bads. A physicaltchemical rnethod for reducing soluble organic materia( from wastewaler elfiuent; The column -type beds used in this
method will have a flow rate varying from two to eight gallons per minute per square Tool and may be either upllow or downtfow carbon beds. Carton may c
may not be regenerated on the wastewater lrsalmant plant site;
(2) Aerated Lagoons. A basin in which all solids are mafrtlained in suspension and by which biological oxidation or organic mazer is reduced through artificial
acceleralod transfer or oxygen on a flowthrough basis;
(3) Aeration, A process or bringing about Inlimate contact between air or high purity oxygen in a liquid by spraying, agitation or diffusion -,(3a) Extended
Aeration. An activated sludge process utilizing a minimum hydraulic detention time of 18 hours,
(4) Agriculturafly managed site. Any sits on which a crop Is produced, managed, and harvested (Crop ircludes grasses, grains, trees, etc.);
(5) Air Stripping. A process by which the ammonium -ion is first corivened to dissolved ammonia (pH adjuslmenl) wilh the arnmonia then released la the
atmosphere by physical means; or other similar processes which remove petroleum produNs such as benzene, toluene, and xylene:
(6) Carbon Regeneration, The regenerasion of exhausted carbon by 1l,e use of a furnace to provide extremely high temperatures which volatilize and oxidize
absorbed impurities;
(7) Carbonaceous Stage. A st=rte of wastewater treatment designed to 'achieve.'secondary' elflueni linwhs;
(8) Centrifuge. A mechanical device in which cenlrilugal force is used to separate solids from liquids or to separale liquids of di ferenl denscles;
(9) Chemical Addition Systems- Tho addition of chemlcal(s) to wmlawater at an application point for purposes of Improving solids removal, pH adjustment,
alkalinity control, etc.; the capabiity to experiment with different chemi_als and diileranl application points ;o achieve a specific resuh will bo considered one
system; the capability to add chomical(s) to due? units will be rated as ons system; capability to add -a chemical at a diflerent application points lar dif#erent
purposes will result in the systems toeing raled as separate syster's:
(1 0) Chemical Sludge Conditioning. The addilion of a chemical compound such as time, ferric chloride, or a polymer to wal sludge to coalesce the rrass prior
its application to a dewatering dovice;
{11) Closed Cycle Systems. Use of holding ponds or holding itr s ten containmun€ of wasiewater conlaining inorganlc, nonrioxlc materials from sand, gran
crushed siono or oil-ar simil,r operations. Such syriarns shall carry a m.,axinum of two points regardless; of pumping locililiez or any other appurenances:
i t2) Combined Romnvar of Carbonacoous BOD a,nd Nitrogenous Rernoval by NlfM;cation- A sirrlo shoe sy5lom roquired to acfl.7vn permit eft€uent limits on ii',
and arnironia nitrogen within the same biolo-ica1 reactor,
03) Dechlorination, Tho partial or complow revuction of rosidual cN;3Hr9 in a liquid by any cho.mical or pn sicai process;
(tr) Doni;rilicaiion Process• The ronvomion of nitrate -nitrogen io nrtrogon gas;
