(A) No person shall discharge or cause to be discharged any storm water, surface water, groundwater, artesian well water, roof runoff, subsurface drainage, uncontaminated cooling water or unpolluted industrial process waters to any sanitary sewer.
(B) Storm water and all other unpolluted drainage shall be discharged to such sewers as are specifically designated as combined sewers or storm sewers, or to a natural outlet approved by the Superintendent. Industrial cooling water or unpolluted process waters may be discharged, to a storm sewer, combined sewer, or natural outlet with the approval of the Superintendent.
(C) 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; or
(3) 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, underground garbage, whole blood, paunch manure, hair and fleshings, entrails, paper dishes, cups, milk containers, and the like, either whole or ground by garbage grinders.
(D) No person shall discharge or cause to be discharged the following described substances, materials, waters, or wastes if it appears likely in the opinion of the Superintendent 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, limb, public property, or constitute a nuisance. The Superintendent will consider such factors as the quantity of subject waste in relation to flows and velocities in the sewers, sewer material and construction, nature of the sewage treatment process, capacity of the sewage treatment plant, degree of treatability of wastes at the sewage treatment plant, and other pertinent factors. The substances prohibited are:
(1) 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° F. and 150° F. (0° C. and 65° C.);
(2) Any garbage that has not been property shredded. The installation and operation of any garbage grinder equipped with a motor of three-fourths horsepower (0.76 hp metric) or greater shall be subject to the review and approval of the Superintendent;
(3) Any waters or wastes containing strong acid iron pickling wastes, or concentrated platting solutions whether neutralized or not;
(4) Any waters or wastes containing objectionable or toxic substances; or wastes exerting an excessive chlorine requirement, to such degree than any such material received in the composite sewage at the sewage treatment works exceeds any limits that may be established by the Superintendent for such materials;
(5) Any waters or wastes containing phenols or other taste or odor-producing substances, in such concentrations exceeding limits which may be established by the Superintendent as necessary, after treatment of the composite sewage, to meet the requirements of state, federal, or other public agencies of jurisdiction for such discharge to the receiving waters;
(6) 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;
(7) Material which exert or cause:
(a) Unusual concentrations in inert, suspended solids (such as, but not limited to, Fuller’s earth, lime slurries and lime residues) or of dissolved solids (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) Unusual B.O.D., chemical oxygen demand or chlorine requirements in such quantities as to constitute a significant load on the sewage treatment works; or
(d) Unusual volume of flow or concentration of wastes constituting slugs as defined in this subchapter.
(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 other agencies having jurisdiction over discharge to the receiving waters.
