(A) General prohibition. Pollutants introduced into POTW’s by a non-domestic source shall not pass through the POTW or interfere with the operation or performance of the works. These general prohibitions and the specific prohibitions in division (B) below apply to all nondomestic sources introducing pollutants into a POTW whether or not the source is subject to other Natural Pretreatment Standards or any national, state, or local pretreatment.
(B) Specific prohibitions. Wastewater discharged into the sewer collection system and POTW shall not contain toxins or other pollutants in an amount or concentration that endangers public safety and physical integrity of the collection system and POTW or cause violation of effluent or water quality limitations. In addition, the following pollutants shall not be introduced into a POTW:
(1) Pollutants which create a fire or explosion hazard in the POTW;
(2) Pollutants which will cause corrosive structural damage to the POTW, but in no case discharges with pH lower than 6.5;
(3) Solid or viscous pollutants in amounts which will cause obstruction to the flow in the POTW resulting in interferences;
(4) Any pollutant, including oxygen demanding pollutants (BOD, and the like) released in a discharge at a flow rate and/or pollutant concentration which will cause interference with the POTW; and
(5) Heat in amounts which will inhibit biological activity in the POTW resulting in interference, but in no case heat in such quantities that the temperature at the POTW Treatment Plan exceeds 40°C (104°F).
(C) All discharges shall be prohibited except those that meet the criteria from “Domestic Wastewater.” BOD concentration shall not exceed 250 mg/l and the total suspended solids concentration shall not exceed 250 mg/l.
(D) Any new connections from inflow sources into the sanitary sewer portions of the sewer system shall be prohibited.
(E) No person may discharge to public sewers any waste, which by itself or by interaction with other wastes may:
(1) Injure or interfere with wastewater treatment processes or facilities;
(2) Constitute a hazard to humans or animals; or
(3) Create a hazard in receiving waters of the wastewater treatment plant effluent.
(F) All discharges shall be prohibited except those that meet the criteria for “Domestic Wastewater.” Biochemical oxygen demand (BOD) concentration shall not exceed 250 milligrams. Suspended Solids (SS) shall not exceed 250 milligrams. This amount of 250 milligrams is the maximum limit for average domestic wastewater.
(G) All industrial discharges are prohibited. At the present time there are no industrial users in the town. If an industrial user should desire to locate in the town and make use of the sewage system, an Industrial Cost Recovery System shall be initiated in accordance with EPA and state regulations at that time to compensate for this use of the system.
