(A) Except as hereinafter provided, no person shall discharge, or cause to be discharged, any of the following described waters or wastes to any public sewer:
(1) Any liquid or vapor having a temperature higher than 150°F;
(2) Any water or waste which may contain more than 100 parts per million by weight of fat, oil, or grease;
(3) Any gasoline, benzene, naphtha, fuel oil, or other flammable or explosive liquid, solid, or gas;
(4) Any garbage that has not been properly shredded;
(5) Any ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastic, wood, paunch manure, or any other solid or viscous substance capable of causing obstruction to the flow in sewers or other interference with the proper operation of the sewage works;
(6) Any waters or wastes having a pH lower than 5.5 or higher than 9.0, or having any other corrosive property capable of causing damage or hazard to structures, equipment, and personnel of the sewage works;
(7) Any waters or wastes containing a toxic or poisonous substance in sufficient quantity to injure or interfere with any sewage treatment process, constitute a hazard to humans or animals, or create any hazard in the receiving waters of the sewage treatment plant;
(8) Any waters or wastes containing suspended solids of such character and quantity that unusual attention or expense is required to handle such materials at the sewage treatment plant;
(9) Any noxious or malodorous gas or substance capable of creating a public nuisance;
(10) Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the Superintendent in compliance with applicable state or federal regulations;
(11) Any waters or wastes containing substances which are not amenable to treatment or reduction by the wastewater treatment processes employed, or are amenable to treatment plant effluent, cannot meet the requirements of other agencies having jurisdiction over discharge of the receiving waters. Each user, which discharges any toxic pollutants which causes an increase in the cost of treating the effluent or the sludge of the city wastewater treatment facility, shall pay for such increased costs; or
(12) Any waters or wastes which, by interaction with other waters or wastes in the public sewer system, release obnoxious gases, form suspended solids which interfere with the collection process, or create a condition deleterious to structures and treatment processes.
(B) If any waters or wastes are discharged, or are proposed to be discharged, to the public sewers, which waters contain substances or possess the characteristics enumerated above, and which in the judgment of the Superintendent may have a deleterious effect upon the wastewater facilities, process, equipment, or receiving water, or which create a hazard to life or constitute a public nuisance, the Superintendent may:
(1) Reject the wastes;
(2) Require pretreatment to an acceptable condition for discharge to the public sewers;
(3) Require control over the quantities and rates of discharge; and/or
(4) Require payment to cover the added cost of handling and treating the wastes not covered by existing taxes or sewer charges.
(C) If the Superintendent permits the pretreatment or equalization of waste flows, the design and installation of the plants and equipment shall be subject to the review and approval of the Superintendent and the State Department of Water and Natural Resources.
