A. No person shall discharge or cause to be discharged any storm water, foundation drain water, ground water, roof runoff, surface drainage, cooling waters, or any other unpolluted water to any sanitary sewer.
B. No user shall contribute or cause to be contributed, directly or indirectly, any pollutant or wastewater contaminant which will cause pass through, cause interference with, inhibition of, or potential problem to the operation or performance of the POTW.
C. 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 requirements. A user shall not contribute the following substances to the POTW:
1. Any liquids, solids, or gases that result in toxic gases, vapors or fumes within the POTW in quantities that may cause acute worker health and safety problems, or be hazardous in any other way to the operation of the POTW or its employees as outlined in 40 CFR 403.5(b)(7). At no time shall two (2) successive readings on a meter capable of reading LEL (lower explosive limit) at a point at the nearest accessible point to the POTW in a sanitary sewer, at the point of discharge into the POTW, or at any point in the POTW be more than five percent (5%) nor any single reading greater than ten percent (10%). Materials for which discharge is prohibited under this subsection include, but are not limited to, gasoline, kerosene, naphtha, benzene, toluene, xylene, ethers, alcohols, ketone, aldehydes, peroxides, chlorates, perchlorates, bromates, polychlorinated biphenyls, polybrominated biphenyls, carbides, hydrides, Stoddard solvents and sulfides.
2. 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 hazardous in any other way to the POTW or to the operation of the POTW. At no time shall the waste stream have a closed cup flashpoint of less than one hundred forty degrees Fahrenheit (140°F) or sixty degrees centigrade (60°C) (the RCRA ignitability standard for liquid characteristic waste) using the test methods specified in 40 CFR section 261.21. (Examples include, but are not limited to: cyanide, gasoline, kerosene, benzene, toluene, alcohols, polychlorinated biphenyls, and Stoddard solvents.)
3. Solid or viscous pollutants in amounts which will cause obstruction to the flow in the sanitary sewer and/or POTW resulting in interference with the operation of the wastewater treatment facilities, including, but not limited to: grease, garbage with particles greater than one-half inch (1/2") in any dimension, animal gut or tissue, paunch manure, bones, hair, hides or fleshings, entrails, whole blood, feathers, ashes, cinders, sand, spent lime, stone or marble dust, metal, glass, straw, shavings, grass clippings, rags, spent grains, spent hops, wastepaper, wood, plastics, glass grindings, polishing wastes, or tumbling and deburring stones.
4. Any petroleum oil, nonbiodegradable cutting oil, or products of mineral oil origin in amounts that cause pass-through or interference.
5. Any wastewater which will cause corrosive structural damage to the POTW, but in no case wastewater having a pH less than five (5.0) or greater than ten (10.0).
6. 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.
7. 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 are sufficient to prevent entry into sewers for their maintenance and repair or endanger POTW or sewer workers' health or safety.
8. 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. Substances discharged to the POTW shall not affect sludge use or disposal criteria developed pursuant to RCRA, SWDA, the clean water act, the toxic substances control act, or state regulation subtitle C part 391 applicable to the sludge management plan being used.
9. Any substance which will cause the POTW to violate its NPDES permit or the receiving water quality standards.
10. Any wastewater having a temperature at the point of discharge which will inhibit biological activity in the POTW treatment plant, resulting in interference. In no instance shall wastewater be introduced to the sewer system which exceeds forty degrees centigrade (40°C) (104°F).
11. Any wastewater containing pollutants released at a flow or concentration which a user knows or has reason to know will cause interference to the POTW or will pass through the POTW.
12. Any wastewater containing any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by state or federal regulations. (Ord. 2005-10, 3-15-2005)
13. Any wastewater containing BOD5, COD, total solids, suspended solids, ammonia nitrogen, or phosphorus of such character and quantity that unusual attention or expense is required to handle such materials at the POTW. A user may be permitted by specific, written discharge permit through the village in which agreement to discharge such BOD5, COD, suspended solids, ammonia nitrogen or phosphorus may be provided using special charges, payments or provisions for treatment and analysis.
14. Ammonia nitrogen in amounts that would cause a violation of the water quality standards of the receiving waters of the POTW.
15. Any wastewater containing toxic pollutants in sufficient quantity, either singly or by interaction to injure, interfere with or cause potential problem with any POTW treatment processes or facilities, constitute a hazard to humans or animals, or to exceed the standards established in the existing act, or the act as it may be amended.
16. Any trucked or hauled pollutants, unless at points designated and approved by the POTW.
17. Any slug discharge.
18. Any discharge which causes the transmittance of the POTW's final effluent to fall below sixty five percent (65%) at two hundred fifty four (254) nanometers.
19. Any wastewater which imparts color which cannot be removed by treatment processes, such as, but not limited to, dye wastes and vegetable tanning solutions, which consequently imparts color to the treatment plant's final effluent.
20. Detergents, surface active agents, or other substances which may cause excessive foaming at the POTW.
21. Medical wastes, including any wastewater containing organisms, including viruses, considered pathogenic and/or detrimental to POTW organisms other than by direct excrement.
22. Wastewater or wastes containing iron pickling wastes or concentrated plating solutions whether neutralized or not.
23. Any sludge, screenings or other residues from the pretreatment of non-residential wastes.
24. 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) that causes potential problems or interferes with POTW operations.
25. Wastewater or wastes containing substances which are not amendable to treatment or reduction by the POTW treatment processes employed, or are amendable to treatment only to such degree that the POTW effluent cannot meet the requirements of agencies having jurisdiction over discharge to the receiving waters.
26. Any wastewater causing the POTW effluent to fail a toxicity test.
Compliance with the provisions of this section shall be required on the effective date of the promulgation of this article. (Ord. 2005-10, 3-15-2005; amd. Ord. 2006-34, 8-22-2006; Ord. 2011-18, 6-28-2011; Ord. 2021-08, 4-27-2021)
