(A) General prohibitions. No user shall introduce or cause to be introduced into the POTW any pollutant or wastewater which causes pass through or interference. These general prohibitions apply to all users of the POTW.
(B) Specific Prohibitions. No user shall introduce or cause to be introduced into the POTW the following pollutants, substances, or wastewater:
(1) Pollutants which create a fire or explosive hazard in the POTW, including, but not limited to, waste streams with a closed-cup flashpoint of less than 140°F (60°C) using the test methods specified in 40 CFR 261.21;
(2) Wastewater having a pH less than 5.5 or more than 11.5, or otherwise causing corrosive structural damage to the POTW or equipment;
(3) Fats, oils and grease (FOG) and solid or viscous substances in amounts which will cause obstruction of the flow in the sewer collection system or POTW resulting in interference;
(4) Pollutants, including oxygen-demanding pollutants (BOD, and the like), 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; or any wastewater treatment or sludge process, which will constitute a hazard to humans or animals;
(5) Wastewater having a temperature which will inhibit biological activity in the treatment plant resulting in interference, but in no case wastewater which has a temperature higher than 104°F or 40°C;
(6) Petroleum oil, nonbiodegradable cutting oil, used motor vehicle anti-freeze, motor oil, brake fluid, transmission fluid, hydraulic fluid, oil-based paint, paint thinners or products of mineral oil origin, in amounts that will cause interference or pass through; but in no case greater than 25 mg/L;
(7) Pollutants which result in the presence of toxic gases, vapors, or fumes within the sewer collection system or POTW in a quantity that may cause acute worker health and safety problems;
(8) Trucked or hauled pollutants;
(9) Noxious or malodorous liquids, gases, solids, or other wastewater which, either singly or by interaction with other wastes, are sufficient to create a public nuisance or a hazard to life, or to prevent entry into the sewers for maintenance or repair;
(10) Wastewater which imparts color which cannot be removed by the treatment process, which consequently imparts color to the treatment plant’s effluent, thereby violating the Utilities wastewater discharge permit;
(11) Wastewater containing any radioactive wastes or isotopes except in compliance with applicable IDEM or Federal regulations and only after written notification of the Utility Director;
(12) Storm water, surface water, ground water, artesian well water, roof runoff, any and all subsurface drainage including sump pump discharges, swimming pool drainage, condensate, deionized water, noncontact cooling water, and unpolluted wastewater, unless specifically authorized by the Utility Director;
(13) Sludges, screenings, or other residues from the pretreatment of industrial wastes;
(14) Medical wastes, except as specifically authorized by the Utility Director or IDEM in a discharge permit;
(15) Wastewater causing, alone or in conjunction with other sources, the treatment plant’s effluent to fail a toxicity test;
(16) Detergents, surface-active agents, or other substances which may cause excessive foaming in the POTW;
(17) Wastewater causing two readings on an explosion hazard meter at the point of discharge into the POTW, or at any point in the POTW, of more than 10% or any single reading over 25% of the lower explosive limit.
(C) 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.
