maintained and operated as a non -discharge system to prevent the discharge of any wastes
resulting from the operation of this program.
2. This permit shall become voidable in the event of failure of the residuals program to
adequately protect the assigned water quality standards of the surface waters and
groundwaters.
3. The issuance of this permit shall not relieve the Permittee of the responsibility for damages

such time as it is distributed to the buyer. If an alternate storage site is to be used, approval
must be obtained from the Division of Water Quality.
4. No other residuals other than those specified under Condition 11 2 above may be
distributed. The Permittee shall request and obtain a permit amendment from the Division
of Water Quality for each additional residual source prior to acceptance of that residual.

residuals program by the Certification Commission. The Permittee must also employ a
certified back-up operator of the appropriate type to comply with the conditions of Title
15A NCAC 8A, .0202.
Adequate provisions shall be taken to prevent wind erosion and surface runoff from
conveying pollutants from the residuals treatment area onto the adjacent property or into
any surface waters.
8. A label shall be affixed to the bag or other container in which residuals that are sold or
given away for application to the land, or an information sheet shall be provided to the
person who receives the residuals sold or given away in an other container for application
to the land. The label or information sheet shall contain the following information:

.0ta04 DEFINITIONS
The following delinitions shall apply throughout this Subchapter.
(1) Activated Carbon Beds, A physlcallchem€cal method for reducing soluble organic material from wastewater effluent; The coiumn-type beds used in this
method will have a Itow rate varying from two to eight gallons per minute per square foot and may be ehher upflow or downflow carbon beds. Carbon may or
may not be regenerated on the wastewater treatmenl plant site;
(2) Aerated Lagoons. A basin in which all solids are maintained In suspension and by which biological oxidation or organic matter is reduced through artl6cialiy
accelerated transfer of oxygen on a flow -through basis;
(3) Aeration. A process of bringing about intlmate contact between air or high purity oxygen In a liquid by spraying, agitation or diffuslon;(3a) Extended
Aeration, An activated sludge process utilizing a minimum hydraulic detention time of 18 hours.
(4) Agr€cullurany 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 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 xylens;
(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 limits;
(8) Centrifuge. A mechanical device In which centrifugal force Is used to separate solids from liquids or to separate liquids of different denshfas; -
