amended, and other applicable Laws, Rules, and Regulations
PERMISSION IS HEREBY GRANTED TO THE
Town of Ramseur
Randolph County
FOR THE
operation of an active sewage sludge unit consisting of a 10-acre lined lagoon and the associated piping in

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 program.
3. in the event that the sewage sludge unit is not operated satisfactorily, including the creation

drainage way,
d. 50 feet between the active sewage sludge unit and property lines (if the original permit
was issued with the buffer distance to property line as 100 feet, updated maps must be
submitted and new acreage delineated for the buffer to be reduced),
e. 10 feet between the active sewage sludge unit and any interceptor drains or surface
water diversions (upslope),
f. 25 feet between the active sewage sludge unit and any interceptor drains or surface
water diversions (downslope),
g. 25 feet between the active sewage sludge unit and any groundwater lowering and
surface drainage ditches.
5. A copy of this permit shall be maintained at the sewage sludge site when residuals are being
disposed during the life of this permit. A spill prevention and control plan shall be

MU DEFINrrK f4.S
The following dellnhions shall apply throughout this Subchapter,
(1) Activated Carbon Beds. A phys caYchemical method tot reducing soluble organic material imm wastewater effluent; The column -type beds used In this
method will have a flow rile varying from two to eight galion6 per mirwre per square foot and may be ehher uprlow or downtlow carbon beds. Carbon may or
may not be regenerated on the wastewater treatment plant she;
(2) Aerated Lagoons. A basin In which all solids are maintained In suspensiort and by which biological oxidation or organic matter Is reduced through art'rficlalty
accelerated transfer of oxygen on a flow -through basis;
(3) Aeration. A process of b6aging about inilmate contact between air or high purity oxygen In a liquid by spraying, aghatlon or dltfuslon;(3a) Extended
Aeration. An activated sludge process utilizing a minimum hycitatilc detention time of i6 hours.
(4) Agriculturally, managed she. Any she on which a Crop is prcduced, managed, and harvested (Crop Includes grasses, grairc, tie", etc.):
(5) Air Sirfippeng. A process by which the ammonium Ion is first convened to dissolved ammonia (pH adjustment) with the ammonia then released to the
atmosphare by physical means; or other similar processes which remove petmleum products such as benzene, toluene, and xylene;
(6) Carbon Regeneration. The rageneratlon of exhausted carbon by the use of a lumace to provide extremely high lempermures which vo[atlilze and oxidize the
ab6orbad Impurhlas;
(7) Carbonaceous Stage. A slags of wastewater treatment designed to achieve 'secondary' effluent Ilmhs;
(a) Centrifuge. A mechanlca.1 device in which centrifugal force Is used to separate solids from 5qulds or to separate liquids of tftfferent denshas;
(9) Chemical Addition Systems- The additlon of chemical(s) to wastewater at an application point for purposes of Improving solids removal, pH adjustment.
alkalinity control, etc.; the capability to experiment whh different chemicals and dhfererd application points to achieve a specific result wlil be considered one
systam; the capability to add chamical(s) to dual units will be rated as ore system; capability to add a chemical at a d lerent application polnis for different
purposes w111 result in the systems being rated as separate systamt;
(10) Chemical Sludge Conditioning. The addition of a chemical compound such as fame, ferric chloride, or a polymer to wet sludge to coalesce the mass prior to
As application to a dewaiering device;
(11) Closed Cycle Systems. Use of holding ponds or holding tanks for containment of wastewater containing Inorganic, non -toxic materials from sand, gravel,
crushed Mons. or other similar operations. Such systems shall carry a maximum of two points regardless of pumping lacilhles or any other appurtenances:
(12) Combined Removal of Carbonaceous BOD and Nitrogenous Removal by Nhdication- A single stago system regvired to achieve pearl; effluent llrrtts on BOD
and ammonia nhrogen within the same biological reactor,
(13) Deehlorinatlon. The partial or compfef a reduction of residual chlorine in a llquld by any chemical or physkal process;
(14) DenitrKIcation Process. The cortverslon of nitrate -nitrogen to nitrogen gas;
