(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.
(B) These general prohibitions apply to all the users of the POTW whether or not the user is subject to national categorical pretreatment standards or any other nation, state or local pretreatment standards or requirements.
(C) A user may not discharge the following substances to the POTW:
(1) Unpolluted waters. Any unpolluted waters such as infiltration/inflow to any sanitary sewer. Storm water and all other unpolluted drainage shall be discharged to the sewers as are specifically designed as storm sewers or to a natural outlet approved by the Superintendent and DEM. Unpolluted industrial cooling water or process waters may be discharged on approval of the Superintendent and DEM to a storm sewer or natural outlet;
(2) Liquids, solids or gas that causes fire or explosion. 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. At no time shall two successive readings on an explosion hazard meter, at the point of discharge in the system (or at any point in the system) be more than 5% nor any single reading over 10% of the Lower Explosive Limit (LEL) of the meter. Materials specifically prohibited from discharge into the POTW include gasoline, kerosene, naphtha, fuel oil and any other substances which the town, the state or EPA has notified the user is a fire hazard or a hazard to the system;
(3) Solid or viscous substances; obstruction. 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 dimensions, animal guts or tissues, paunch manure, bones, hairs hides or fleshing, entrails, whole blood, feathers, ashes, cinders, sand, spent lime, stone or marble dust, metal, glass, straw, shavings, grass clippings, rags, spent grains, spent hops, waste paper, wood, plastics, gas, tar, asphalt, residues, residues from refining or processing of fuel or lubricating oil, mud or glass grinding or polishing wastes;
(4) pH factor. 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) Toxic substances. 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 to exceed the limitation set forth in a categorical pretreatment standard;
(6) Noxious or malodorous liquids, gas or solids. 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) Unsuitable for reclamation. Any substance which may cause the POTW’s effluent or any other product of the POTW such as residues, sludge or scum, to be unsuitable for 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 being 33 U.S.C. § 1345; any criteria, guidelines or regulations affecting sludge use or disposal developed pursuant to the Solid Waste Disposal Act being 42 U.S.C. §§ 6901 et seq., the Clean Air Act being 33 U.S.C. §§ 1251 et seq., the Toxic Substances Control Act, being 15 U.S.C. §§ 2601 et seq. or state criteria applicable to the sludge management method being used;
(8) Substance which affects permits. Any substance which will cause the POTW to violate its NPDES and/or state disposal system permit or the receiving water quality standards;
(9) Color. Any wastewater with objectionable color not removed in the treatment process, such as, but not limited to, dye wastes and vegetable tanning solutions;
(10) Temperature. Any wastewater, liquid or vapors having a temperature higher than 150°F;
(11) BOD. Any pollutants, including oxygen demanding pollutants (BOD and the like) releasing at a flow and/or pollutant concentration which a user knows or has reason to know will cause interference;
(12) Radioactive wastes. Any wastewater containing any radioactive wastes or isotopes of a half-life or concentration as may exceed limits established by the town in compliance with applicable state and/or federal regulations; or
(13) Slug. Quantities of flow, concentrations or both which constitute a slug as defined herein.
(D) When the Superintendent determines that a user(s) is discharging any of the above-enumerated substances in amounts as to interfere with the operation of the POTW, the Superintendent shall:
(1) Advise the user(s) of the impact of the discharge; and
(2) Develop effluent limitations for the user(s) to correct the discharge.
