(A) 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 the wastes can harm either the sewers, sewage treatment process, or equipment; would have an adverse effect on the receiving stream; can endanger life, limb, or public property; or constitute a nuisance. In forming his or her opinion as to the acceptability of these wastes, the Superintendent will give consideration to the factors as quantities of subject wastes in relation to flows and velocities in the sewers; the nature of the sewage treatment process capacity of the treatment plant, and the degree of treatability of the wastes in the plant; and other pertinent factors.
(B) The substances which may be prohibited, restricted, or regulated at the discretion of the Superintendent are:
(1) Any liquid or vapor having a temperature higher than 150°F (65°C);
(2) 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);
(3) Any garbage that has not been properly shredded (garbage grinders of three-fourths hp or more are subject to inspection and approval by the Superintendent);
(4) Any waters or wastes containing strong acid, iron pickling wastes, or concentrated plating solutions, whether neutralized or not;
(5) Any waters or wastes containing iron, chromium, copper, zinc, and 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 treatment works exceeds the limits established by the Superintendent;
(6) Any waters or wastes containing phenols or other taste or odor-producing substances, in concentrations exceeding limits established by the Superintendent as necessary, after treatment of the composite sewage, to meet the requirements of state, federal, or other public agencies having jurisdiction over the discharges to the receiving waters;
(7) Any radioactive wastes or isotopes of the half-life or concentration exceeding the limits established by the Superintendent in compliance with applicable state or federal regulations;
(8) Any waters or wastes having a pH in excess of 9.5;
(9) Any materials which exert or cause:
(a) Unusual concentration of 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 solution;
(c) Unusual B.O.D., chemical oxygen demand, or chlorine requirement in the quantities as to constitute a significant load on the treatment works; and/or
(d) Unusual volume of flow or concentrations of wastes constituting slugs as defined in § 53.01. (10) Waters or wastes containing substances which are not amenable to treatment or reduction by the treatment process employed, or are treatable only to the degree that the treatment plant effluent cannot meet the requirements of agencies having jurisdiction over the receiving waters.
