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 sewer, 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. In forming his opinion 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 sewer, materials of construction of the sewer, nature of the sewage treatment process, capacity of the sewage treatment plant, degree of treatability of wastes in the sewage treatment plant, and maximum limits established by regulatory agencies. The substances prohibited are:
(A) Any liquid or vapor having a temperature higher than One Hundred Fifty degrees Fahrenheit (150F), (65C).
(B) Any waters or wastes containing toxic or poisonous materials; or oils, whether emulsified or not, in excess of One Hundred (100) mg/l or containing substances which may solidify or become viscous at temperatures between Thirty-Two (32) and One Hundred Fifty degrees Fahrenheit (150F), (O and 65C).
(C) Any garbage that has not been properly shredded. The installation and operation of any garbage grinder equipped with a motor of three-fourths (3/4) horsepower (0.76 hp metric) or greater shall be subject to the review and approval of the Village.
(D) Any waters or wastes containing strong acid, iron pickling wastes, or concentrated plating solution whether neutralized or not.
(E) Any waters or wastes containing iron, chromium, copper, zinc, or similar objectionable or toxic substances; or wastes exerting an excessive chlorine requirement, to such degree that any such material received in the composite sewage at the sewage treatment works exceeds the limits established by the Village for such materials.
(F) Any waters or wastes containing phenols or other waste odor-producing substances, in such concentration exceeding limits which may be established by the Village as necessary after treatment of the composite sewage, to meet the requirements of the State, Federal, or other public agencies of jurisdiction for such discharge to the receiving waters.
(G) Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the Village in compliance with applicable State or Federal regulations.
(H) Any mercury or any of its compounds in excess of 0.0005 mg/l as Hq at any time except as permitted by the Village in compliance with applicable State and Federal regulations.
(I) Materials which exert or cause:
(1) unusual concentrations or 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);
(2) excessive discoloration (such as, but not limited to, dye wastes and vegetable tanning solutions);
(3) unusual BOD, chemical oxygen demand, or chlorine requirements in such quantities as to constitute a significant load on the sewage treatment works;
(4) unusual volume of flow or concentrations of wastes constituting "slugs" as defined herein. (Reference Appendix #7)
(J) Waters or wastes containing substances which are not amendable to treatment or reduction by the sewage treatment processes employed or are amendable to treatment only to such degree that the sewage treatment plant effluent cannot meet the requirements of agencies having jurisdiction over discharge to the receiving waters.
(K) Any waters or wastes having a pH in excess of 9.5.
(L) Any cyanide in excess of 0.025 mg/l at any time except as permitted by the Village in compliance with applicable State and Federal regulations.
