(1) Existing ordinance governing storm sewer installation remains in effect.
(c) General Discharge Prohibitions and Limitations.
(1) Prohibitions of wastewater discharge. No person shall discharge or cause or allow to be discharged into the public sewer, wastes designated as prohibited wastes pursuant to 40 CFR 128.131 and amendments thereto, including, but not limited to, the following:
A. Explosive mixtures: Liquids, solids, or gases which, by reason of their nature or quantity, are, or may be, sufficient to cause fire or explosion or be injurious in any other way to the sanitary sewage system or to the operation and maintenance of the system. At no time shall two successive readings on an explosion hazard meter, at the point of discharge into the sewer system be more than five percent (5%) nor any single reading over ten percent (10%) of the lower explosive limit (L.E.L.) of the meter. Prohibited materials include, but are not limited to, gasoline, kerosene, naphtha, benzene, toluene, xylene, ethers, alcohols, ketone, aldehydes, peroxides, chlorates, perchlorates, bromate, carbides, hydrides and sulfides.
B. Corrosive water: Waters or wastes having a Ph lower than 6.0 or greater than 9.0 and having any other corrosive property capable of causing damage or hazard to structures, equipment, and personnel of the Wastewater Disposal Facilities. If City water exceeds Ph 9.0, the upper limit shall be raised to the Ph of City water.
C. Solid or viscous wastes: Solid or viscous substances in quantities or of such size capable of causing obstruction to the flow in sewers, or other interference with the operation of the wastewater disposal facilities, such as, but not limited to, ashes, bones, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, unground garbage, whole blood, paunch manure, hair and fleshings, entrails, and paper dishes, cups, and milk containers, either whole or ground by garbage grinders, fats or grease, from food preparation or fryers.
D. Toxic wastes: Waters or wastes containing toxic or poisonous solids, liquids or gases in sufficient quantity, either singly or in combination with other wastes, to injure or interfere with any waste treatment process, render treatment process residues unfit for reclamation or reuse, cause violations of the treatment works NPDES discharge permit, constitute a hazard to humans or animals, create a public nuisance or create any hazard or water quality violation in the receiving waters of the public wastewater treatment facility. Radioactive wastes and wastes containing matter designated as toxic pollutants by the USEPA pursuant to Section 307(a) of the Federal Act, and amendments thereto, shall not be discharged to the public sewer, without prior written approval of the Direct. Current listings of the toxic pollutants and hazardous substances shall be available from the Director.
(2) Limitations on wastewater discharges.
A. Except as provided herein, no person shall discharge or cause or allow to be discharged into the public sewer wastes which exceed the limitations, as set forth in this chapter. The Director may establish more stringent limitations and/or add additional wastewater parameters with limitations as necessary to protect the public disposal facilities or the public health, safety, and welfare; or to comply with other agencies having jurisdiction over discharge from the Wastewater Treatment Facility.
B. Upon proper application therefor, on such forms and in accordance with such regulations as the Director shall prescribe and the payment of the appropriate fees established, the Director may issue Wastewater Discharge Permits, which shall be valid for a period of time as the Director may allow but in any event not to exceed three (3) years , subject to the provisions that may be established by the City should it be determined that such excess will cause damage to, or exceed the capacity of the City’s wastewater disposal facilities to meet the minimum standards of the Act or any other applicable law.
C. No person shall discharge or cause to be discharged into the public sewer, wastes which exceed the following limitations:
1. Wastewater having a temperature higher than one hundred four (104) degrees Fahrenheit (F).
2. Wastewater containing more than one hundred (100) mg/l of fats, wax, grease or oils, whether emulsified or not, or containing substances which may solidify or become viscous at temperatures between thirty-two (32) degrees F. and one hundred four (104) degrees F.
3. Any garbage which has not been properly shredded as defined herein. The installation of any garbage grinder equipped with a motor of three-fourths (3/4) horsepower or greater shall require the prior written approval of the Director.
4. Solids, liquids, or gasses, which are noxious or malodorous due to their nature, quantity, or interaction with other wastes.
5. Quantities of flow, concentrations, or both which constitute a “slug” as defined herein.
6. Wastes with objectionable color not removable by the treatment process.
7. Materials that by themselves, or when mixed with other components in wastewater create a noxious odor from the system.
(3) Prohibitions on discharge of unpolluted water. No person shall discharge or cause to be discharged to a sanitary sewer any unpolluted water which includes, but is not limited to, storm water, ground water, roof runoff, subsurface drainage, or uncontaminated cooling water or industrial process waters. Any existing roof drain connections to sanitary sewers shall be connected to an available storm sewer shall be disconnected above ground in the manner approved by the Director. The owner of all buildings situated within the City is required at his expense to disconnect all existing roof drain connections to sanitary sewers in accordance with the provisions of this chapter within 90 days after the date of official notice so to do.
(4) Limitations on point of discharge. No person shall discharge any substances directly into a manhole or other opening in a public sewer other than through an approved building sewer.
(5) Holding tank waste. No person shall discharge any holding tank waste into a public sewer unless he has obtained written approval from the Director. Unless otherwise allowed by the Director, approval must be secured for each separate discharge.
(d) Federal Categorical Pretreatment Standards.

The Director shall notify all affected users of the applicable reporting requirements under 40 CFR, Section 403.12.
(2) Modification of federal categorical pretreatment standards. Where the City’s wastewater treatment facility achieves consistent removal of pollutants limited by Federal Pretreatment Standards, the City may apply to the State Approval Authority for modifications of specific limits in the Federal Pretreatment Standards. “Consistent Removal” shall mean reduction in the amount of a pollutant or alteration of the nature of the pollutant by the wastewater treatment facility to a less toxic or harmless state in the effluent which is achieved by the system in 95 percent of the samples taken when measured according to the procedures set forth in Section 403.7(c)(2) and amendments thereto of (Title 40 of the Code of Federal Regulations, Part 403) “General Pretreatment Regulations for Existing and New Sources of Pollution” promulgated pursuant to the Act. The City may modify pollutant discharge limits in the Federal Pretreatment Standards if the requirements contained in 40 CFR, Part 403, Section 403.7, are fulfilled and prior approval from the Approval Authority is obtained.
(3) State requirements. State requirements and limitations on discharge shall apply in any case where they are more stringent than federal requirements and limitations or those in this chapter.
(e) City’s Right of Revision. Consistent with Federal regulations, the City reserves the right to establish by ordinance more stringent limitations or requirements on discharge to the Wastewater Disposal Facility if deemed necessary to comply with the objectives of this chapter.
