Legal Documents of Halls

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 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 in any other way to the POTW or to the operation of the POTW. At no time shall two successive readings on an explosion hazard meter, at the point of discharge into the POTW 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 or have a closed cup flashpoint of less than 140°F using the test method specified in 40 CFR 261.21. Prohibited materials include, but are not limited to, gasoline, kerosene, naphtha, benzene, toluene, xylene, ethers, alcohols, ketones, aldehydes, peroxides, chlorates, perchlorates, bromates, carbides, hydrides, sulfides and any other substance which the town, the state or EPA has notified the user is a fire hazard or a hazard to the system.
2. Solid or viscous substances which may cause obstruction to the flow in a sewer or other interference with the operation of the wastewater treatment facilities such as, but not limited to: grease, garbage with particles greater than one-half inch (1/2") in any dimension, animal guts or tissues, 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, 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.
3. Any wastewater having a pH less than 6.0 or more than 9.0, unless the wastewater having any other corrosive property capable of causing damage or hazard to structures, equipment, and/or personnel of the POTW.
4. Any wastewater containing toxic pollutants in sufficient quantity, either singly or by interaction with other pollutants, to injure or interfere with any POTW 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 a categorical pretreatment standard.
5. 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 acute worker health and safety problems or are sufficient to prevent entry into the sewers for maintenance and repair.
6. 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 non-compliance 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.
7. Any substance which will cause the POTW to violate its NPDES permit or the receiving water quality standards.
8. Any wastewater with objectionable color which causes discoloration of the POTW treatment plant effluent to the extent that the NPDES permit is violated, such as, but not limited to, dye wastes and vegetable tanning solutions.
9. 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 which will cause the wastewater temperature at the introduction into the POTW to exceed 40°C (104°F).
10. Any pollutants, including oxygen demanding pollutants, such as BOD, NH3-N, and oil and grease, released at a flow rate and/or pollutant concentration which will cause interference to the POTW. In no case shall a discharge to the POTW have a flow rate or contain concentration or qualities of pollutants that exceed for any time period longer than fifteen (15) minutes more than five (5) times the average twenty-four (24) hour concentration, quantities, or flow during normal operation.
11. Any wastewater containing any radioactive waste or isotopes of such half-life or concentration as may exceed limits established by the control authority in compliance with applicable state or federal regulations.
12. Any wastewater which causes a hazard to human life or creates a public nuisance.
13. Any wastewater containing fats, wax, grease, petroleum oil, non-biodegradable cutting oil or products of mineral oil origin, or other substances which may solidify or become viscous at temperatures between 0° (32°F) and 40°C (104°F) and/or cause interference or pass-through at the POTW treatment plant.
14. Any stormwater, surface water, groundwater, roof runoff, subsurface drainage, uncontaminated cooling water, or unpolluted industrial process waters. Stormwater and all other unpolluted drainage shall be discharged to storm sewers, or to a natural outlet approved by the control authority and the Tennessee Department of Environment and Conservation. Industrial cooling water or unpolluted process waters may be discharged on approval of the control authority and the Tennessee Department of Environment and Conservation, to a storm sewer or natural outlet.

15. Any trucked or hauled pollutants except at discharge points designated by the POTW.

    When the control authority determines that a user is contributing to the POTW, any of the above enumerated substances in such amounts as to interfere with the operation of the POTW, the control authority shall:

    1. Advise the user of the impact of the contribution on the POTW; and
    2. Develop effluent limitation(s) for such user to correct the interference with the POTW.
