(A) No person shall discharge or cause to be discharged any of the following described waters or wastes to any public sewers:
(1) Any gasoline, benzene, naphtha, fuel oil or other flammable or explosive liquid, solid or gas.
(2) Any waters or wastes containing toxic or poisonous solids, liquids or gases in sufficient quantity, either singly or by interaction with other wastes, to injure or interfere with any sewage treatment process, constitute a hazard to humans or animals, create a public nuisance or create any hazard in the receiving waters of the sewage treatment plant.
(3) Any waters or wastes having a pH lower than six, or higher than nine, or having any other corrosive property capable of causing damage or hazard to structure, equipment and personnel of the sewage works, or that interferes with any treatment process.
(4) 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, plastics, wood, unground garbage, whole blood, paunch, manure, hair and fleshings, entrails, paper, dishes, cups, milk containers, etc., either whole or ground by garbage grinder.
(5) Any wastewater containing any cations, anions, compounds or substances exceeding the concentrations listed below as measured at the point of discharge into the town's sewage collection system or at the sampling manhole(s) approved by the town.

(6) 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 or create a toxic effect in the receiving waters of the wastewater works.
(7) Any wastewater containing toxic pollutants which exceed the limitations set forth in the applicable Federal Categorical Pretreatment Standards or other pretreatment standard or regulations issued by EPA or the IDEM. A toxic pollutant identified pursuant to Section 307(a) of the Federal Water Pollution Control Act, as amended.
(8) Where more than one standard (local, state or federal) applies to discharge limitations for a particular pollutant, the standard which shall apply is the most stringent of the appropriate limitations.
(B) No person shall discharge or cause to be discharged the following described substances, materials or wastes if it appears likely in the opinion of the Town Board that such wastes can harm either the sewers, sewage treatment process or equipment, have an adverse effect on the receiving stream, or can otherwise endanger life, health, public property or constitute a nuisance. In forming its opinion as to the acceptability of any wastes, the Board will give consideration to all factors addressed under this subchapter including, but not limited to, the quantities of subject wastes in relation to flows and velocities in the sewers, materials of construction of the sewers, nature of the sewage treatment process, capacity of the sewage treatment plant, degree of treatability of wastes in the sewage treatment plant and other pertinent factors. The substances prohibited are:
(1) Any liquid or vapor having a temperature higher than 150°F. or 65°C.
(2) Any water or waste containing fats, wax, grease or oils, whether emulsified or not, in excess of 100 mg/l or containing substances which may solidify or become viscous at temperatures between 32° and 150°F. or 0° and 65°C.
(3) Any garbage that has not been properly shredded. The installation and operation of any garbage grinder equipped with a motor of 3/4 horsepower (0.76 hp) metric or greater shall be subject to the review and approval of the Wastewater Superintendent.
(4) Any waters or wastes containing taste or odor producing substances, in such concentrations exceeding limits which may be established by the Board as necessary, after treatment of the composite sewage, to meet the requirements of the state, federal or other public agencies of jurisdiction for such discharge to the receiving waters.
(5) Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the Town Board in compliance with applicable state or federal regulations.
(6) Materials which exert or cause:
(a) Concentrations of inert suspended solids exceeding 250 mg/l (such as, but not limited to, Fullers earth, lime slurries and lime residues) or concentrations of dissolved solids exceeding 600 mg/l (such as, but not limited to, sodium chloride and sodium sulfate).
(b) Excessive discoloration (such as, but not limited to, dye wastes and vegetable tanning solutions).
(c) Excessive B.O.D., chemical oxygen demand or chlorine requirements in quantities greater than 250 mg/l constitute a significant load on the sewage treatment works.
(d) Excessive volume of flow or concentration of wastes constituting “slugs” as defined herein.
(7) Any water or waste that causes corrosive structural damage to the treatment works or collection system or any sewer or appurtenances owned or operated by the town.
(8) Waters or wastes containing substances which are not amenable to treatment or reduction by the sewage treatment processes employed, or are amenable to treatment only to such degree that the sewage treatment plant effluent cannot meet the requirements of agencies having jurisdiction over discharge to the receiving waters.
(9) Any substance which will cause the wastewater treatment plant to violate its NPDES permit.
(10) It shall be unlawful for any person to place, deposit, permit or cause to be deposited, or discharged in any manner whatsoever, any substance into a sewer at a point different than the permitted sewer connection to the sanitary sewer system.
(C) The Town Board may impose mass-based discharge limitations in terms of pounds of specific pollutants discharged per day for new major contributors or major contributors with any increase in discharges. These mass limitations may result in lower concentration-based specific discharge limits than those established in § 51.35.
(D) A nondomestic discharger of any listed or characteristic hazardous wastes under the Resource Conservation and Recovery Act (RCRA) must immediately notify the utility of the amount and frequency of the hazardous waste discharge.
(E) Existing industrial or major contributors shall be required to meet the discharge limitations established in § 51.35(A) and (B) within three years from the date of the adoption of this subchapter.
