(A) No user shall contribute or cause to be contributed, directly or indirectly, any pollutant or wastewater which will interfere with the operation or performance of the P.O.T.W. These general prohibitions apply to all users of a P.O.T.W., whether or not the user is subject to federal categorical pretreatment standards or any other national, state, or local pretreatment standards or requirements. A user may not contribute the following substances to any P.O.T.W.:
(1) 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 P.O.T.W. or to the operation of the P.O.T.W. At no time shall two successive readings on an explosion hazard meter, at the point of discharge into the system (or at any point in the system), be more than 5% nor any single reading over 10% of the lower explosive limit (L.E.L.) of the meter. Prohibited materials include, but are not limited to, gasoline, kerosene, naphtha, benzene, toluene, xylene, ethers, alcohols, ketones, aldehydes, peroxides, chlorates, perchlorates, bromates, carbides, hydrides and sulfides, and any other substances which the town, the state, or E.P.A. has notified the user is a fire hazard or a hazard to the system;
(2) Solid or viscous substances which may cause obstruction to the flow in a sewer or other interference with the operation of the wastewater treatment facilities, such as, but not limited to: grease, 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, 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;
(3) Any wastewater having a pH less than 5, unless the P.O.T.W. is specifically designed to accommodate the wastewater, or wastewater having any other corrosive property capable of causing damage or hazard to structures, equipment, and/or personnel of the P.O.T.W.;
(4) Any wastewater containing toxic pollutants 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 P.O.T.W., or to exceed the limitation set forth in a categorical pretreatment standard. A toxic pollutant shall include, but not be limited to, any pollutant identified pursuant to the Clean Water Act, being §§ 33 U.S.C. 1317(q) et seq.;
(5) 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 maintenance and repair;
(6) Any substance which may cause the P.O.T.W.’s effluent, or any other product of the P.O.T.W. such as residues, sludges, or scums, to be unsuitable for reclamation and reuse or to interfere with the reclamation process. In no case shall a substance discharged to the P.O.T.W. cause the P.O.T.W. to be in noncompliance 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, being 33 U.S.C. §§ 6901 et seq.; the Clean Air Act, being 42 U.S.C. §§ 7401 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;
(7) Any substance which will cause the P.O.T.W. to violate its N.P.D.E.S. and/or state disposal system permit or the receiving water quality standards;
(8) Any wastewater with objectionable color not removed in the treatment process, such as, but not limited to, dye wastes and vegetable tanning solutions;
(9) Any wastewater having a temperature which will inhibit biological activity in the P.O.T.W. treatment plant resulting in interference, but in no case wastewater with a temperature at the introduction into the P.O.T.W. which exceeds 40°C (104°F), unless the P.O.T.W. treatment plant is designed to accommodate the temperature;
(10) Any pollutants, including oxygen demanding pollutants (B.O.D. and the like), released at a flow rate and/or pollutant concentration which a user knows or has reason to know will cause interference to the P.O.T.W. In no case shall a sludge load have a flow rate or contain concentration or qualities of pollutants that exceed, for any time period longer than 15 minutes, more than five times the average 24-hour concentration, quantities, or flow during normal operation;
(11) Any wastewater containing any radioactive wastes or isotopes of a half-life or concentration as may exceed limits established by the Superintendent in compliance with applicable state or federal regulations; and
(12) Any wastewater which causes a hazard to human life or creates a public nuisance.
(B) When the Superintendent determines that a user(s) is contributing to the P.O.T.W. any of the above enumerated substances in amounts as to interfere with the operation of the P.O.T.W., the Superintendent shall:
(1) Advise the user(s) of the impact of the contribution on the P.O.T.W.; and
(2) Develop effluent limitation(s) for the user to correct the interference with the P.O.T.W.
