No user shall discharge or deposit or cause or allow to be discharged or deposited into the sewer system any wastewater which contains:
(A) Any liquid or vapor having a temperature higher than 104ºF (40ºC);
(B) Any substance which may solidify or become viscous at temperatures between 32ºF and 104ºF (0ºC and 40ºC);
(C) Oil and grease concentrations or amounts from industrial facilities violating federal, local or state pretreatment standards;
(D) Wastewater from industrial facilities containing floatable fats, wax, grease or oils;
(E) Wax, grease or oil concentrations of mineral origin exceeding 50 mg/l whether emulsified or not;
(F) Wastewater having a pH of less than six or more than eight;
(G) 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 facilities or to the operation of the system. At no time shall explosive or hazardous material be discharged in to the sewer system. Prohibited materials include, but are not limited to, gasoline, kerosene, naphtha, benzene, toluene, zylene, ethers, alcohols, keyones, aldehydes, peroxides, chlorates, perchalorates, bromates, carbides, hydrides, sulfides or any pollutant identified in the federal priority pollutant list adopted by the U.S. EPA;
(H) Noxious or malodorous solids, liquids or gasses, which, either singly or by interaction with other wastes, are capable of creating a public nuisance or hazard to life, or acre or may be sufficient to prevent entry into a sewer or its maintenance and repair;
(I) Garbage that has not been ground or comminuted to such a degree that all particles will be carried freely in suspension under flow conditions normally prevailing in the public sewers, with no particle greater than one-half inch in any dimension;
(J) Solid or viscous wastes which will or may cause obstruction to the flow in a sewer, or otherwise interfere with the proper operation of the wastewater treatment system. Prohibited materials include, but are not limited to, grease, uncomminuted garbage, animal guts or tissues, paunch, manure, bones, hair, hides of fleshings, entrails, whole blood, feathers, ashes, cinders, sand, spent lime, stone or marble dilutes, metal, glass, straw, shavings, grass clippings, rags, spent grains, spent hops, waste paper, wood, plastic, tar, asphalt residues, residues from refining of processing of fuel or lubricating oil and similar substances;
(K) Any unpolluted water which will increase the hydraulic loading on the plant including, but not limited to, any storm water, surface water, ground water, roof run-off water, subsurface drainage, uncontaminated cooling water or uncontaminated industrial process waters. The applies strictly to all new connections. All existing connections may be approved or rejected after review of hardship and/or other considerations by the village;
(L) Radioactive wastes or isotopes of such half-life or concentration that they do not comply with municipal, state or federal regulations or orders issued by the appropriate authority having control over their use and which will or may cause damage to the sewage facilities or create dangerous or hazardous conditions for the personnel operating the system;
(M) Wastes with objectionable color not removable by the treatment process;
(N) Any waste which will cause corrosion or deterioration of the sewage system. All wastes discharged to the public sewer system must have a pH value in the range of 6 to 8 standard units. Prohibited materials, include, but are not limited to, acids, sulfides, concentrated chloride and fluoride compounds and substances which will react with water to form acidic products;
(O) Any substance determined by the village to be toxic in concentrations in excess of tolerable limits as promulgated by the village;
(P) Any chemical elements or compounds or other waste or odor substances which are not susceptible to treatment or that will pass through the system; and
(Q) Any chemical element or compounds or other substances which, may interfere with the biological process or efficiency of the treatment process.
