(A) No person shall contribute or cause to be contributed, directly or indirectly, any pollutant or wastewater which singly or by interaction with other pollutants may cause interference with the POTW or pass-through the POTW. These general prohibitions apply to all such users of a POTW whether or not the user is subject to National Categorical Pretreatment Standards or any other national, state, or local pretreatment standards or requirements.
(B) No person shall discharge or cause to be discharged any of the following described waters or wastes to any public sewers:
(1) Pollutants which create a fire or explosion hazard in the POTW, including but not limited to waste streams with a closed-cup flashpoint of less than 140°F or 60°C using the test methods specified in 40 C.F.R. § 261.21;
(2) Petroleum oil, nonbiodegradable cutting oil, or products of mineral oil origin in amounts that will cause interference of pass-through;
(3) Pollutants which result in the presence of toxic gases, vapors, or fumes within the POTW in a quantity that may cause acute worker health and safety problems;
(4) Any trucked or hauled pollutants, except at discharge points designated by the POTW;
(5) Any waters or waste having a pH lower than 6.0, or having any other corrosive property capable of causing damage or hazard to structures, equipment, and personnel of the sewage works;
(6) Solid or viscous substances in quantities or of such size capable of causing obstruction to the flow in sewers, or other interference with the proper operation of the sewage works, such as but not limited to ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastic, wood, unground garbage, whole blood, paunch, manure, hair, and fleshing, entrails, and paper dishes, cups, milk containers, etc., either whole or ground by garbage grinders;
(7) Any substance which, either singly or by interaction with other wastes, is sufficient to create a public nuisance or hazard to life or is sufficient to prevent entry into the sewers for maintenance and repair;
(8) Any unusual volume of flow or concentration of wastes constituting “slugs” as defined in this chapter;
(9) Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the Director in compliance with applicable state or federal regulations;
(10) Any wastewater having a temperature which will inhibit biological activity in the POTW treatment plant resulting in interference, but in no case heat in such quantities that the temperature at the introduction into the POTW which exceeds 40°C (104°F);
(11) Any substance which may cause the POTW’s effluent or any other product of the POTW, such as residues, sludges, or scum, to be unsuitable for reclamation and reuse or to interfere with the reclamation process. In no case shall a substance discharge to the POTW cause the POTW to be in noncompliance with a sludge use or disposal 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; and
(12) Any substance which will cause the POTW to violate its NPDES and/or state disposal system permit or the receiving water quality standards.
