No person shall discharge or cause to be discharged excessive amounts of the following described substances, materials, waters or wastes thereby harming 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. In forming his decision as to the acceptability of these wastes, the Superintendent will give consideration to those factors as the quantities of subject wastes in relation to flows and velocities in the sewers, materials of construction of sewers, nature of the sewage treatment process, capacity of the sewage treatment plant, degree of treatability of wastes in the sewage treatment plant and other pertinent factors as provided in NPDES. The substances prohibited are those that do not meet requirements of the state, federal or other public agencies of jurisdiction for such discharge to the receiving waters as follows:
(A) Any liquid or vapor having a temperature higher than 150°F. (62°C.)
(B) 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 and 150°F. (0 and 65°C.)
(C) Any garbage that has not been properly shredded. The installation and operation of any garbage grinder equipped with a motor of ¾ horsepower (0.76 hp metric) or greater shall be subject to the review and approval of the Superintendent.
(D) Any waters or wastes containing strong acid iron pickling wastes, or concentrated plating solutions whether neutralized or not.
(E) Any waters or wastes containing iron, chromium, copper, zinc, and 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 Treatment Works exceeds the capability of secondary treatment plant to reduce the pollutants in the composite waste at the plant to levels acceptable by NPDES.
(F) Any waters or wastes containing phenols or other taste or odor producing substances in such concentration in the composite exceeding limits, after treatment of composite sewage, to meet the requirements of state, federal, and 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 the limits after treatment of the composite sewage in compliance with applicable state or federal regulations.
(H) Any waters or wastes having a pH in excess of 9.0.
(I) Materials which exert or cause:
(1) Unusual concentration of inert suspended solids (such as, but not limited to, Fullers 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 those quantities as to constitute a significant load on the sewage treatment works.
(4) Unusual volume of flow or concentration of wastes constituting “slugs” as defined in § 51.001.
(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 that degree that the sewage treatment plant affluent cannot meet the requirements of other agencies having jurisdiction over discharge to receiving waters.
