    a. Any gasoline, benzene, naphtha, fuel oil, or other flammable or explosive liquid, solid or gas.
    b. Any waters or wastes containing toxic or poisonous solids, liquids, or gases in sufficient quantity, either singularly or by interaction with other wastes, to injure or interfere with any sewage treatment process, constitute a hazard to humans or animal, create a public nuisance, or create any hazard in the receiving waters of the POTW.

In making his decision as to the acceptability of these wastes, the Superintendent will give consideration to such factors as the quantities of subject wastes in relation to flows and velocities in the sewers, materials of construction of the sewers, nature of the wastewater treatment process, capacity of the wastewater treatment plant, degree of treatability of wastes in the wastewater treatment plant, and pertinent factors.

If any waters or wastes are discharged, or are proposed to be discharged, to the public sewers, which waters contain the prohibited substances or characteristics which, in the judgment of the Superintendent, may have a deleterious effect on the POTW, or receiving waters, or which otherwise create a hazard life or constitute a public nuisance, the Superintendent may:
    a. Reject the wastes;
    b. Require pretreatment to an acceptable condition for discharge to the public sewers

    d. Require payment to cover the added cost of handling and treating the wastes not covered by existing taxes or sewer charges, under the provisions of 50.20.
