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 sewage works. These general prohibitions apply to all such users of the sewage works whether or not the user is subject to national, state, or local pretreatment standards or requirements. A person or user may not contribute the following substances to any sewage works:
(A) 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 sewage works or to the operation of the POTW. 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 10% of the lower explosive limit (LEL) of the meter. Prohibited materials include, but are not limited to, gasoline, diesel fuel, kerosene, naphtha, benzene, toluene, xylene, ethers, alcohols, ketones, aldehydes, peroxides, chlorates, perchlorates, bromates, carbides, hydrides and sulfides and any other substance which the village, the state or EPA has notified the user is a fire hazard or a hazard to the system.
(B) Solid or viscous substances which may cause obstruction to the flow in the sewage works or other interference with the operation of the POTW 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, wipes (including those labeled as "flushable"), spent grains, spent hops, waste paper, wood, plastics, gas, tar, asphalt residues, residues from refining or processing of fuel or lubrication oil, mud, glass grinding or polishing wastes, or butchers offal.
(C) 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.
(D) Any wastewater having a pH less than six, unless the POTW is specifically designed to accommodate such wastewater, or wastewater having any other corrosive property capable of causing damage or hazard to structures, equipment, and/or personnel of the POTW.
(E) Any wastewater containing toxic pollutants in sufficient quantity, either singly or by interaction with other pollutants, to:
(1) Injure or interfere with any wastewater treatment process.
(2) Constitute a hazard to humans or animals.
(3) Create a toxic effect on the receiving waters of the POTW or to exceed the limitation set forth in a categorical pretreatment standard.
(F) 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.
(G) Any substance which will cause the POTW to violate its limits and restrictions set forth in the village's NPDES permit.
(H) Any substance with objectionable color not removed in the treatment process, such as but not limited to, dye wastes and vegetable tanning solutions.
(I) Any wastewater having a temperature which will inhibit biological activity in the POTW resulting in interference; but in no case, wastewater with a temperature at the introduction into the POTW which exceeds 40°C (104°F) or any liquid or vapor discharged into the sewage works having a temperature higher than 60°C (140°F).
(J) Any unpolluted water, including, but not limited to non-contact cooling water.
(K) Any waters or wastes containing acid, metallic pickling wastes, or concentrated plating solutions.
(L) Any toxic radioactive isotopes of such half-life or concentration as exceeds limits established by federal regulations. The radioactive isotopes Iodine-131 and Phosphorus-32 used in hospitals are not prohibited, if they are properly diluted before being discharged into the sanitary sewer.
(M) Any waters or wastes containing any toxic substances in quantities that are sufficient to interfere with the biochemical processes of the POTW that will pass through the POTW into the receiving stream in amounts exceeding the standards set by federal, interstate, state or other competent authority having jurisdiction or contaminate sewage sludge, that contain iron or any other toxic ions, compounds, or substances in concentrations or amounts exceeding the limits established from time to time by the village that exert an excessive chlorine requirement on the POTW.
(N) Any unusual volume of flow or concentration of wastes constituting slugs that for a duration of five minutes or more have a concentration or flow of more than five times the average concentration of the BOD, the suspended solids or flow of the customer's sewage discharged during a 24-hour period of normal operation and are released in a single extraordinary discharge event which causes interference to the POTW.
(O) 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. In no case shall a substance discharged to the POTW cause the POTW to be in noncompliance with sludge use or disposal criteria, guidelines or regulations developed under Section 405 of the Act, any criteria or guidelines of or pursuant to the Solid Waste Disposal Act, Resource Conservation and Recovery Act, the Clean Air Act, the Toxic Substances Control Act, or state criteria applicable to the sludge management method being used.
(P) Any wastewater which causes a hazard to human life or creates a public nuisance.
