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 whether or not they are subject to categorical pretreatment standards or any other National, State, or local pretreatment standards or requirements.
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, including, but not limited to, wastestreams with a closed cup flashpoint of less than one hundred forty degrees Fahrenheit (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 9.5, or otherwise causing corrosive structural damage to the POTW or equipment;
3. Solid or viscous substances in amounts which will cause obstruction of the flow in the POTW resulting in interference but in no case solids greater than 0.5 inch or 1.27 centimeters;
4. Pollutants, including oxygen demanding pollutants (BOD, etc.), released in a discharge at a flowrate and/or pollutant concentration that, either singly or by interaction with other pollutants, will cause interference with the POTW;
5. Wastewater having a temperature greater than one hundred fifty degrees Fahrenheit (150°F) (65.6°C), or which will inhibit biological activity in the treatment plant resulting in Interference, but in no case wastewater which causes the temperature at the introduction into the treatment plant to exceed one hundred four degrees Fahrenheit (104°F) (40°C);
6. Petroleum oil, non-biodegradable cutting oil, products of mineral oil origin, or synthetic oils in amounts that will cause interference or pass through;
7. Pollutants that result in the presence of toxic gases, vapors, or fumes within the POTW in a quantity that may cause acute worker health and safety problems;
8. Trucked or hauled pollutants, except at discharge points designated by the public works coordinator in accordance with section 8-13-3-4 of this chapter;
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 health, or to prevent entry into the sewers for maintenance or repair;
10. Wastewater which imparts color that 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 Village's NPDES permit;
11. Wastewater containing any radioactive wastes or isotopes;
12. Stormwater, surface water, ground water, artesian well water, roof runoff, subsurface drainage, swimming pool drainage, condensate, deionized water, noncontact cooling water, and unpolluted wastewater, unless specifically authorized in writing by the public works coordinator;
13. Sludges, screenings, or other residues from the pretreatment of industrial wastes or from industrial processes;
14. Medical wastes, except as specifically authorized by the public works coordinator or in an individual wastewater 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 that might cause excessive foaming in the POTW;
17. Any liquid, 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 in any other way to the POTW or to the operation of the POTW. At no time shall two (2) successive readings on an explosion meter, at the point of discharge into the system (or at any point in the system), be more than five percent (5%) nor any single reading over ten percent (10%) of the lower explosive limit (LEL) of the meter;
18. Grease, animal guts or tissues, paunch manure, bones, hair, hides or fleshings, entrails, whole blood, feathers, ashes, cinders, sand, spent lime, stone or marble dusts, metal, glass, straw, shavings, grass clippings, rags, spent grains, spent hops, waste paper, wood, plastics, gas, tar asphalt residues, residues from refining or processing of fuel or lubricating oil, mud, or glass grinding or polishing wastes;
19. Any substance which will cause the Village to violate its NPDES permit and/or other disposal system permits;
20. Any wastewater, which in the opinion of the Public Works Coordinator can cause harm either to 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;
21. The contents of any tank or other vessel owned or used by any person in the business of collecting or pumping sewage, effluent, septic tank waste, or other wastewater unless said person has first obtained testing and approval by the Village and paid all fees assessed for the privilege of said discharge;
22. Any hazardous wastes as defined in State regulations or in 40 CFR Part 261;
23. Persistent pesticides and/or pesticides regulated by the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA);
24. Sewage sludge, except in accordance with the Village's NPDES permit.
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. (Ord. 701, 12-8-2020)
