(A) It shall be unlawful for any person to discharge or cause to be discharged any pollutant or wastewater which will interfere with the operation and/or performance of the POTW. These general prohibitions apply to all such users of the POTW, whether or not the user is subject to National Categorical Pretreatment Standards or any other national, state or local pretreatment standards or requirements. A user may not discharge the following substances to the POTW:
(1) Any unpolluted waters such as infiltration or inflow to any sanitary sewer. Stormwater and all other unpolluted drainage shall be discharged to such sewers as are specifically designed as storm sewers or to a natural outlet approved by the approving authority and the DEM. No untreated sanitary wastewater shall be discharged to any storm sewer or natural outlet;
(2) Any liquids, solids or gases which by reason of their nature or quantity are or may be sufficient, either alone or by interaction with other substances, to cause fire or explosion or be injurious in any other way to the POTW or to the operation of the POTW. Materials specifically prohibited from discharge into the POTW include gasoline, kerosene, naphtha, fuel oil, and any other substances which the local government, the state or the EPA has notified the user is a fire hazard or a hazard to the system;
(3) Solid or viscous substances which may cause obstruction to the flow in a sewer or other interference with the operation of the POTW, such as but not limited to: floatable oil, garbage with particles greater than one-half inch in any dimension, animal guts or tissues, paunch manure, bones, hair, hides or fleshings, entrails, whole blood, feathers, ashes, cinders, sand, spent lime, stone or marble dust, metal, glass, straw, shavings, grass clippings, rags, spent grains, spent hops, wastepaper, wood, plastics, gas, tar, asphalt residues, residues from refining or processing of fuel or lubricating oil, mud, or glass grinding or polishing wastes;
(4) Any wastewater having a pH less than 6.0 or greater than 9.0 or wastewater having any other corrosive property capable of causing damage or hazard to structures, equipment and/or personnel of the POTW;
(5) Any wastewater containing toxic substances in sufficient quantity, either singly or by interaction with other pollutants, to injure or interfere with any wastewater treatment process, constitute a hazard to humans or animals, create a toxic effect in the receiving waters of the POTW, or exceed the limitation set forth in a categorical pretreatment standard;
(6) Any noxious or malodorous liquids, gases or solids which, either singly or by interaction with other wastes, are sufficient to create a public nuisance or hazard to life or are sufficient to prevent entry into the sewers for their maintenance and repair;
(7) Any substance which may cause the POTW’s effluent or any other product of the POTW such as residues, sludges or scums to be unsuitable for reclamation and reuse or to interfere with the reclamation process where the POTW is pursuing a reuse and reclamation program. In no case shall a substance discharged to the POTW cause the POTW to fail to be in compliance with sludge use or disposal criteria, guidelines or regulations developed under §405 of the Act; any criteria, guidelines or regulations affecting sludge use or disposal developed pursuant to the Solid Waste Disposal Act, the Clean Air Act, the Toxic Substances Control Act, or state criteria applicable to the sludge management method being used;
(8) Any substance which will cause the POTW to violate its NPDES and/or state disposal system permit or the receiving water quality standards;
(9) Any wastewater with objectionable color not removed in the treatment process, such as but not limited to dye wastes and vegetable tanning solutions;
(10) Any wastewater, liquid or vapors having a temperature higher than 150°F;
(11) Any pollutants, including oxygen-demanding pollutants (BOD and the like), released at a flow and/or pollutant concentration which a user knows or has reason to know will cause interference;
(12) Any wastewater containing any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the local government in compliance with applicable state and/or federal regulations; and
(13) Quantities of flow, concentrations or both which constitute a slug.
(B) When the approving authority determines that a user is discharging any of the substances enumerated in division (A) of this section in such amounts as to interfere with the operation of the POTW, the approving authority shall:
(1) Advise the user of the impact of the discharge and applicable penalties associated with the continuation of such discharge; and
(2) Develop effluent limitations for such user to correct the discharge.
(C) No statement contained in this section shall be construed as preventing any special agreement or arrangement between the town and any person whereby an industrial waste of unusual strength or character may be admitted into the sanitary sewers by the town after approved pretreatment.
