No person shall discharge or cause to be discharged any of the following, to wit:
(A) Any liquid or vapor having a temperature higher than 150°F, 65°C;
(B) Any water or waste containing fats, wax, grease or oils, whether emulsified or not, in excess of 100 milligrams per liter, of which not more than 25 milligrams per liter is soluble oils, or containing substances which may solidify or become so highly viscous so as to retard flow in the sewer system at temperatures between 32°F and 150°F (0°C and 65°C);
(C) Any garbage that has not been properly shredded. The installation and operation of any garbage grinder (other than in a residence) may be subject to the review and approval of the Superintendent;
(D) Any waters or wastes containing strong acid iron, pickling aster or concentrated plating solutions, whether neutralized or not;
(E) Any waters or wastes exceeding the following maximum allowable limits or similar objectionable or toxic substances or wastes exerting an excessive chlorine requirement to such a degree that any such material received in the composite sewage at the sewage treatment works exceeds the limits established by the Superintendent for such materials:
Material
|
Amount
|
Material

(F) Any waters or wastes containing phenols or other waste or odor-producing substances, after treatment of the composite sewage, in such concentrations exceeding limits which may be established by the Superintendent as necessary to meet the requirements of the state, federal or other public agencies of jurisdiction for such discharge to the respective waters;
(G) 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;
(H) Any waters or wastes having a pH of less than 6 or in excess of 9;
(I) Materials which exert or cause:
(1) Unusual concentrations of inert suspended solids, such as, but not limited to, fuller’s earth or lime slurries (and such as, but not limited to, sodium chloride and sodium sulfate);
(2) Excessive discoloration (such as, but not limited to, dye wastes and vegetable tanning solutions);
(3) Unusual BOD, chemical oxygen demand and chlorine requirements in such quantities so as to constitute a significant load on the sewage treatment plant; or
(4) Unusual volume of flow or concentration of wastes.
(J) 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 a degree that the sewage treatment plant effluent cannot meet the requirements of other agencies having jurisdiction over discharge to the receiving waters.
