The following prohibitive discharge standards shall apply:
(a) 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 or will pass through the POTW.
(b) The following general prohibitions shall apply to all users of the POTW, whether or not a user is subject to National Categorical Pretreatment Standards or any other National, State or local pretreatment standard or requirement. A user shall not contribute the following pollutants, substances or wastewater to the POTW:
(1) Any liquids, solids or gases which by reason of their nature or quantity are or may be sufficient, either alone or by interaction with other substances, to cause fire or explosion or be injurious or hazardous in any other way to the POTW or to the operation of the POTW; in no case pollutants with a closed cup flashpoint of less than 140 degrees Fahrenheit or sixty degrees Celsius using the test methods specified in 40 CFR 261.21.
(2) Solid or viscous pollutants in amounts which will cause obstruction to the flow in the POTW resulting in interference with the operation of the wastewater treatment facilities.
(3) Any wastewater which will cause corrosive structural damage to the POTW, but in no case wastewater having a pH less than 5.0 or greater than 9.5, unless more strictly limited elsewhere in this chapter.
(4) Any wastewater containing incompatible 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, cause a violation of the water quality standards of the receiving waters of the POTW, exceed the limitation set forth in a National Categorical Pretreatment Standard (when effective) or in Section 1046.10 or create a public nuisance.
(5) Any noxious or malodorous liquids, gases or solids which, either singly or by interaction with other wastewaters, are sufficient to create a public nuisance or hazard to life or are sufficient to prevent entry into sewers for their maintenance and repair.
(6) Any substance discharged to the POTW that will cause the POTW to be in noncompliance with sludge use or disposal criteria, guidelines or regulations developed under Section 405 of the Act or any criteria, guidelines or regulations affecting sludge use or disposal developed pursuant to the RCRA, SWDA, the Clean Water Act, the Toxic Substances Control Act or State criteria applicable to the sludge management method being used.
(7) Any substance which will cause the POTW to violate its NPDES permit or the receiving water quality standards.
(8) Any wastewater having a temperature at the point of discharge to the POTW which will inhibit biological activity in the POTW treatment plant, resulting in interference. In no case shall wastewater liquid or vapor be introduced to the POTW sewers which exceeds sixty-five degrees Celsius (150 degrees Fahrenheit) and/or exceeds forty degrees Celsius (104 degrees Fahrenheit) at the POTW treatment plant.
(9) Any pollutants, including oxygen demanding pollutants (BOD, etc.) released in a discharge at a flow rate and/or pollutant concentration which, either singly or by interaction with other pollutants, will cause interference with the POTW.
(10) Any wastewater containing any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by State or Federal regulations.
(11) Fats, oils or greases (FOG) of animal or vegetable origin in concentrations greater than fifty milligrams per liter.
(12) Any wastewater containing BOD, total solids or suspended solids of such character and quantity that unusual attention or expense is required to handle such materials at the sewage treatment plant, provided, however, that a user may be permitted by specific, written agreement with the City, which agreement to discharge such BOD or TSS may provide for special charges, payments or provisions for treating and testing equipment.
(13) Ammonia nitrogen in amounts that would cause a violation of the water quality standards of the receiving waters of the POTW.
(14) Any discharge exceeding the standards established in 35 Ill. Adm. Code. Part 307, as amended.
(15) Any slug discharged to the POTW.
(16) Petroleum oil, nonbiodegradable cutting oil, or products of mineral oil origin in amounts that will cause interference or pass through.
(17) Any pollutant which results in the presence of toxic gases, vapors or fumes within the POTW in a quantity that may cause acute worker health and safety problems.
(18) Any trucked or hauled pollutants, except at a discharge point approved by the City or its authorized designee.
(19) Wastewater which imparts color which cannot be removed by the treatment process, such as, but not limited to, dye wastes and vegetable tanning solutions, which consequently imparts color to the treatment plant's effluent, thereby violating the City's NPDES Permit.
(20) Storm water, surface water, ground water, artesian well, roof runoff, subsurface drainage, swimming pool drainage, condensate, deionized water, non-contact cooling water, and unpolluted wastewater, unless specifically authorized by the City or its authorized designee.
(21) Sludges, screenings, or other residues from the pretreatment of industrial wastes.
(22) Medical wastes, except as specifically authorized by the City or its authorized designee in an individual wastewater discharge permit.
(23) Wastewater causing, alone or in conjunction with other sources, the treatment plant's effluent to fail toxicity tests.
(24) Detergents, surface-active agents, or other substances which might cause excessive foaming in the POTW.
Pollutants, substances or wastewater prohibited by this section shall not be processed or stored in such a manner that they could be discharged to the POTW.
Compliance with the provisions of this section shall be required on the effective date of this chapter.
