(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) Unpolluted waters. This includes uncontaminated storm water, surface water, ground water, roof runoff, subsurface drainage, uncontaminated cooling water or unpolluted industrial process waters to any sanitary sewer. Storm water and all other unpolluted drainage shall be discharged to such sewers as are specifically designated as storm sewers, or to a natural outlet approved by the (Kentucky Department for Environmental Protection). Industrial cooling water or unpolluted process waters may be discharged, on approval of the (Kentucky Department for Environmental Protection), to a storm sewer or natural outlet.
(2) Solid or viscous waters. Solid or viscous substances which will or may cause obstruction to the flow in a sewer, or otherwise interfere with the proper operation of the wastewater treatment system. Prohibited materials include, but are not limited to, grease, uncomminuted garbage, animal guts or tissues, paunch manure, cannery wastes, bones, hair, hides or fleshings, entrails, whole blood, feathers, bulk solids, ashes, cinders, sand, spent lime, stone or marble dust, metal, glass, straw, shavings, grass clippings, rags, spent grains, spent hops, waste paper products, wood, plastic, tar, asphalt residues, painting residues, residues from refining or processing of fuel or lubricating oil, and similar substances.
(3) Explosive mixtures. 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 a wastestream exhibit a closed cup flashpoint of less than 140º F. (60º C.) using the test methods specified in 40 C.F.R. 261.21. Prohibited materials include, but are not limited to gasoline, kerosene, naphtha, benzine, toluene, xylene, ethers, alcohols, ketones, aldehydes, peroxides, chlorates, perchlorates, promates, carbides, hydrides, and any other substances which have a closed cup flashpoint of 140º F. (60º C.) or less, in any substance which the city, state, or EPA has notified the user is a fire hazard or a hazard to the sanitary sewer system.
(4) Improperly shredded garbage. Any garbage that has not been properly shredded, see the definitions in this chapter. Garbage grinders may be connected to sanitary sewers from homes, hotels, institutions, restaurants, hospitals, catering establishments or similar places where garbage originates from the preparation of food in kitchens for the purpose of consumption on the premises or when served by caterers.
(5) Corrosive wastes. Any waste which will cause corrosion or deterioration of the wastewater treatment works. All wastes discharged to the public sewer system must have a pH value in the range of six to nine standard units. Prohibited material, include, but are not limited to, acids, sulfides, concentrated chloride and fluoride compounds and substances which will react with water to form acidic products.
(6) Oils and grease. Any waters or wastes containing fats, wax, grease, or oil, whether emulsified or not, in excess of 100 mg/l or containing substances which may solidify or become viscous at temperatures between 32º or 150º F. (0º and 65 C).
(7) Noxious materials. Noxious or malodorous solids, liquids or gases, which, either single or by interaction with other wastes, are capable of creating a public nuisance or hazard to life, or may be sufficient to prevent entry into a sewer for its maintenance and repair.
(8) Discolored materials. Wastes with objectionable color in the sole discretion of Superintendent or EPA, such as dye waste.
(9) Toxic substances. Any toxic substances in amounts exceeding standards promulgated by the Administrator of the United States Environmental Protection Agency pursuant to Section 307 (a) of the Act, and chemical elements or compounds, phenols, or any other substances which are not susceptible to treatment or which may interfere with the biological processes or efficiency of the treatment system, or that will pass through the system.
(10) Radioactive wastes. Radioactive wastes or isotopes of such half-life or concentration that they do not comply with regulations or orders issued by the appropriate authority having control over their use and which will or may cause damage or hazards to the sewerage facilities or personnel operation the system.
(11) High temperature wastes. Any liquid or vapor having a temperature higher than 104º F., 40º C.
(12) Flow rate or concentration. Any pollutant, including oxygen demanding pollutants (BOD and the like) released in a discharge at a flow rate and/or pollutant concentration which will cause interference with the POTW.
(13) Toxic gases, vapors or fumes. Any pollutants which, either alone or by interaction with other substances, produce toxic gases, vapors or fumes within the POTW in a quantity that may cause acute worker health and safety problems.
(14) Oil products. Petroleum oil, nonbiodegradable cutting oil, or products of mineral oil origin in amounts that will cause interference or pass through at the POTW.
(15) Trucked or hauled pollutants. Any trucked or hauled pollutants, except at discharge points designated by the Superintendent.
(16) Improperly shredded paper products. Any ground paper products such as cups, dishes, napkins, milk products and the like shall not be discharged into the sewerage works.
(17) Medical wastes. Except as specifically authorized by the Superintendent in an individual wastewater discharge permit.
(18) Foaming. Detergents, surface- active agents, or other substances that might cause excessive foaming in the POTW.
(C) Storing of substances. 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.
