No user shall contribute or cause to be contributed, directly or indirectly, any pollutant or wastewater which will interfere with the operation or performance of the POTW. These general prohibitions apply to all users of a POTW whether or not the user is subject to National categorical pretreatment standards or any other National, State or local pretreatment standards or requirements. A user may not contribute the following substances to any public sewer:
(a) Pollutants which create a fire or explosion hazard in the POTW, including but not limited to, wastestream with a closed cup flashpoint of less than 140° Fahrenheit or 60° Centigrade, using the test method specified in 40 CFR 261.21.
(b) Solid or viscous substances which may cause obstruction to the flow in a sewer or cause interference or pass through at the wastewater treatment facilities, such as, but not limited to grease, garbage with particles greater than one-half inch in any dimensions, animal guts or tissues, paunch manure, bones, hair, hides or fleshings, entrails, whole blood, feathers, ashes, sand, spent lime, stone or marble dust, metal, glass, straw, shavings, grass clippings, rags, spent grains, spent hops, waste paper, wood, plastics, tar, asphalt residues, mud, petroleum, oil, nonbiodegradable cutting oil, or products of mineral oil origin or glass grinding or polishing wastes.
(c) Any wastewater having a pH less than 5.5 or higher than 10.0 or having any other corrosive property capable of causing damage or hazard to structures, equipment or personnel of the system.
(d) Any wastewater containing toxic pollutants in sufficient quantity, either singly or by interaction with other pollutants, to injure or interfere with any wastewater treatment process, constitute a hazard to humans or animals, create a toxic effect in the receiving waters of the POTW, or to exceed the limitation set forth in this chapter or a categorical pretreatment standard. A toxic pollutant includes but is not limited to any pollutant identified pursuant to Section 307 (a) of the Act.
(e) Any noxious or malodorous liquids, gases or solids which either singly or by interaction with other wastes are sufficient to create a public nuisance or hazard to life or are sufficient to prevent entry into the sewers for maintenance and repair.
(f) Any substance which may cause the POTW's effluent or any other product of the POTW such as residues, sludges or scums, to be unsuitable for reclamation and reuse or to interfere with the reclamation process. In no case, shall a substance discharged to the POTW cause the POTW to be in noncompliance with sludge use or disposal criteria, guidelines or regulations developed under Section 405 of the Act; any criteria, guidelines or regulations affecting sludge use or disposal developed pursuant to the Solid Waste Disposal Act, the Clean Air Act, the Toxic Substances Control Act, or State criteria applicable to the sludge management method being used.
(g) Any substance which will cause the POTW to violate its NPDES and/or State disposal system permit or the receiving water quality standards.
(h) Any wastewater with objectionable color not removed in the treatment process, such as, but not limited to, dye wastes and vegetable tanning solutions.
(i) Any wastewater having a temperature which will inhibit biological activity in the POTW treatment plant resulting in interference, but in no case wastewater with a temperature at the introduction into the POTW which exceeds 40° C. (104° F.).
(j) Any slugload, which means any pollutant, including oxygen demanding pollutants (BOD, etc.), released in a single extraordinary discharge episode of such volume or strength as to cause interference to the POTW.
(k) Any unpolluted water including, but not limited to noncontact cooling water unless the POTW is designated as a combined sewer.
(1) Any wastewater containing any radioactive wastes or isotopes of such half-life or concentration as exceed limits established by the City in compliance with applicable State or Federal regulations.
(m) Any wastewater which causes a hazard to human life or creates a public nuisance.
(n) Hauled septic or industrial wastes, except at locations and at times as designated by the Superintendent. Any removal of manhole lids, or other access to the sewer system for the purpose of discharging wastes at times and/or locations other than those designated by the Superintendent, or without the expressed permission of the Superintendent, shall be considered a violation and shall be subject to enforcement action, including fines and penalties allowed under this chapter.
