(A) General prohibitions. No person shall discharge or introduce or cause to be discharged or 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 person shall discharge or introduce or cause to be discharged or introduced any of the following described pollutants, substances or wastewater into any public sewer or directly or indirectly into the POTW:
(1) Any gasoline, benzene, naphtha, fuel oil or other pollutants which create a fire or explosive hazard to 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) Any waters or wastes containing toxic or poisonous solids, liquids or gases in sufficient quantity, either singular or by interaction with other wastes, to injure or interfere with any sewage treatment process, constitute a hazard to humans or animals, create a public nuisance or create any hazard in the receiving waters of the sewage treatment plant.
(3) Any waters or wastes having a pH lower than 5.0 or higher than 9.5 or having any other corrosive property capable of causing damage or hazard to structures, equipment, collection systems or personnel of the sewage works, or that interferes with any treatment process.
(4) Solid or viscous substances in quantities or of such size capable of causing obstruction to the flow in sewers, or other interference with the proper operation of the sewage works such as, but not limited to ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, unground garbage, whole blood, paunch, manure, hair and fleshings, entrails, paper, pulp, fiber, paper products, dishes, cups, milk containers and the like, either whole or ground by garbage grinders.
(5) Any wastewater containing toxic pollutants in sufficient quantity, either singularly or by interaction with other pollutants, to injure or interfere with any wastewater treatment process, constitute a hazard to humans or animals, create a toxic effect in the receiving waters of the wastewater works, or to exceed the limitations set forth in the applicable Federal Categorical Pretreatment Standards or other pretreatment standards or regulations issued by EPA or the IDEM. Toxic pollutant(s) are identified pursuant to Section 307(a) of the Federal Water Pollution Control Act.
(6) Any pollutant, including oxygen- demanding pollutants (BOD and the like), released in a discharge at a flow rate and/or pollutant concentration which, either singularly or by interaction with other pollutants, will cause interference with the POTW.
(7) Wastewater or any liquid having a temperature greater that 150°F (65°C), or which will inhibit biological activity in the treatment plant resulting in interference, but in no case wastewater or liquid which causes the temperature at the introduction into the treatment plant to exceed 104°F (40° C).
(8) Trucked or hauled pollutants, except at discharge points designated by the town.

(11) Any water or waste containing fats, wax, grease, or oils, whether emulsified or not, in excess of 100 mg/l or containing substances which may solidify or become viscous at temperatures between 32 and 150ºF or 0 and 65ºC.
(12) Any garbage that has not been properly shredded. The installation and operation of any garbage grinder equipped with a motor of 3/4 horsepower (0.76 hp metric) or greater shall be subject to the review and approval of the town.
(13) Any waters or wastes containing strong acid iron pickling wastes or concentrated plating solutions whether neutralized or not.
(14) Any waters or wastes containing iron, chromium, copper, zinc and similar objectionable or toxic substances; or wastes exerting an excessive chlorine requirement, to such degree that any such material received in the composite sewage at the sewage treatment works exceeds the limits established by the Superintendent for such materials.
(15) Any waters or wastes containing phenols or other taste or odor producing substances, in such concentrations exceeding limits which may be established by the town as necessary, after treatment of the composite sewage, to meet the requirements of the state, federal or other public agencies of jurisdiction for such discharge to the receiving waters.
(16) Materials which exert or cause:
(a) Unusual concentrations of inert S.S. (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).
(b) Unusual S.S., CBOD, BOD, Ammonia-Nitrogen, Phosphorus, or chlorine requirements in such quantities as to constitute a significant load on the sewage treatment works.
(c) Unusual volume of flow or concentration of wastes constituting “slugs” as defined herein.
(17) Waters or wastes containing substances which are not amenable to treatment or reduction by the sewage treatment processes employed, or are amenable to treatment only to such degree that the sewage treatment plant effluent will be compromised.
(18) Any residuals defined as a Hazardous Waste under 40 CFR 261.
(C) If any wastewater is discharged, or is proposed to be discharged, to the sewage works, which such water contains the substances or possess the characteristics enumerated in this chapter, and which in the judgement of the town may have a deleterious effect upon the sewage works, processes, equipment or receiving waters, or otherwise create a hazard to life or constitute a nuisance, the town may:
(1) Require new industries or industries with significant increases in discharges to submit information on wastewater characteristics and obtain prior approval for discharges. For purposes of this requirement, flow increases of 20% or greater, or the discharge of any previously unreported pollutants shall be deemed significant.
(2) Reject the wastewater in whole or in part for any reason deemed appropriate by the town.
(3) Require pretreatment of such wastewater to within the limits of normal domestic sewage as defined herein.
(4) Require control of flow equalization of such wastewater so as to avoid any slug loads or excessive loads that may be harmful to the treatment works.
(5) Require payment of a surcharge on any excessive flows or loadings discharged to the treatment works to cover the additional costs of having capacity for and treating such wastewater. If the town permits the pretreatment or equalization of wastewater flow, the design and installation of the plant and equipment shall be subject to the review and approval of the town and subject to the requirements of all applicable codes, ordinances and laws.
(D) Pre-treatment devices shall be provided by the discharger as necessary for the removal of grease, flammable wastes, sand, or other harmful substances determined to be harmful by the town. All pre-treatment devices shall be of a type and capacity approved by the town or its designee, and shall be readily accessible for cleaning and inspection. The owner and/or operator of pretreatment device equipment shall be required to maintain certified records as to time and date of cleaning and inspection. The pre-treatment equipment shall be cleaned a minimum of once a year with proof of cleaning submitted to the town. The specifications shall be in accordance with the Indiana Plumbing Code and Town of Kouts Standards.
(E) When a discharger is required to provide preliminary treatment, including interceptors or flow equalization facilities, such equipment shall be maintained by the discharger in satisfactory operating condition as determined by the town, at the owner’s expense.
(F) When required by the town, the owner of any property serviced by a building sewer carrying industrial wastes shall install a suitable control manhole, together with such necessary meters and other appurtenances in the building sewer, to facilitate observation, sampling and measurement of the wastes. Such manhole, when required, shall be accessibly and safely located, and shall be constructed in accordance with plans approved by the town. The manhole shall be installed by the owner at his or her expense, and shall be maintained by him or her so as to be safe and accessible at all times. The town, IDEM and EPA shall be permitted to enter all properties for such purposes as inspection, observation, measurement, sampling and testing.
(G) All measurements, tests and analyses of the characteristics of wastewater to which reference is made in this chapter shall be conducted using the methods and procedures in 40 CFR Part 136, and shall be determined at the control manhole provided, or upon suitable samples taken at said control manhole. In the event that no special manhole has been required, the control manhole shall be considered to be the nearest downstream manhole in the sewage works to the point at which the building sewer is connected. Sampling shall be carried out by customarily accepted methods to reflect the effect to constituents upon the sewage works and to determine the existence of hazards to life, limb and property. (The particular analysis involved will determine whether a 24-hour composite of all outfalls of a premises is appropriate or whether a grab sample or samples should be taken. Normally, but not always, CBOD and T.S.S. analyses are obtained from 24-hour composites of all outfalls whereas pH analyses are obtained from periodic grab samples.)
(H) No statement contained in this article shall be construed as preventing any special agreement or arrangement between the town and any industrial user whereby an industrial waste of unusual strength of character may be accepted by the town for treatment, subject to payment therefore, by the industrial user, at such rates as are compatible with the rate ordinance, provided, however, that no special agreement or arrangement may be made with the town which results in the violation of National Pretreatment Standards or local limits.
