(A) No person, municipality, sewer and/or water district shall discharge or cause to be discharged the following described substances, materials, waters, or wastes if it appears likely in the opinion of the Mayor that such wastes can harm either the sewers, sewage treatment process or equipment, have an adverse effect on the receiving stream, or can otherwise endanger life, limb, public property, or constitute a nuisance. In forming such opinion as to the acceptability of these substances, the Mayor will give consideration to such factors as the quantities of subject wastes in relation to flows and velocities in the sewers, materials of construction of the sewers, nature of the sewage treatment process, capacity of the sewage treatment plant, degree of treatability of wastes in the sewage treatment plant, and other pertinent factors. The substances prohibited are:
(1) Any liquid or vapor having a temperature higher than 104º F.
(2) Any water or waste containing oil and grease of animal vegetable origins, fats, wax, grease, or oils, whether emulsified or not, in excess of 100 milligrams per liter, or containing substances which may solidify or become viscous at temperatures between 32º F. and 150º F.
(3) Any garbage that has not been properly shredded. The installation and operation of any garbage grinder equipped with a motor of ¾-horse power (0.76 hp metric) or greater, shall be subject to the review and approval of the Mayor.
(4) Any waters or wastes containing strong acid iron pickling wastes, or concentrated plating solutions whether neutralized or not.
(5) 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 Mayor for such materials.
(6) Any waters or wastes containing phenols or other taste or odor-producing substances, in such concentrations exceeding limits which may be established by the Mayor 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.
(7) Any radioactive wastes or isotopes of such half life or concentration as may exceed limits established by state or federal regulations.
(8) Any waters or wastes having a pH lower than 5.5 or in excess of 10.0.
(9) Materials which exert or cause;
(a) Unusual concentrations or inert suspended solids (such as, but not limited to sodium chloride and sodium sulfate).
(b) Excessive discoloration (such as, but not limited to dye wastes and vegetable tanning solutions).
(c) Unusual B.O.D. chemical oxygen demand, or chlorine requirements in such quantities as to constitute a significant load on the sewage treatment works.
(d) Any hydrogen sulfide levels about 1.9 PPM per water borne test, or any hydrogen sulfide levels above 8.0 PPM per air borne test.
(e) Unusual volume of flow or concentration of wastes constituting slugs, spills, or any by-passing or overflow of untreated wastewater containing substances regulated by this permit, to the sanitary sewer from the permittee's facility. In the event this should occur, the permittee shall immediately notify the Mayor's representative (City Engineer). The Mayor shall have the authority to require significant industrial users to develop a slug control plan.
(10) 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 cannot meet the requirements of other agencies having jurisdiction over discharge to the receiving waters.
(11) Materials discharged that are considered hazardous waste under the Resource Conservation and Recovery Act (RCRA) must be immediately reported to the control authority.
(B) If any waters or wastes are discharged, or are proposed to be discharged to the public sewers, which waters contain the substances or possess the characteristics enumerated in division (A) hereof, and which in the judgment of the Mayor may have a deleterious effect on the sewage works, processes, equipment, or receiving waters or which otherwise create a hazard to life or constitute a public nuisance, the Mayor may:
(1) Reject the wastes;
(2) Require pretreatment to an acceptable condition for discharge to the public sewers;
(3) Require control over the quantities and rates of discharge; or
(4) Require payment to cover the added cost of handling and treating the wastes not covered by existing taxes or sewer charges under the provisions of § 52.46.
(C) If the Mayor permits the pretreatment of equalization of waste flows, the design and installation of the plants and equipment shall be subject to the review and approval of the Mayor, and subject to the requirements of all applicable codes, ordinances, and laws.
(D) Any person who transports septic tank, seepage pit or cesspool contents, liquid industrial waste or other batch liquid waste and wishes to discharge such waste to the public sewer system shall first have a valid Domestic Waste Hauler's Permit. All applicants for a Domestic Waste Hauler's Permit shall complete the application form, pay the appropriate fee and receive a copy of the city's regulations governing discharge to sewers of liquid wastes from trucks. All persons receiving such permits shall agree in writing to abide by all applicable provisions of this section and any other special provisions that may be established by the city as necessary for the proper operation and maintenance of the sewerage system.
(1) Discharge of septic tank, seepage pit, interceptor or cesspool contents or other wastes containing no industrial wastes may be made by trucks holding a valid permit at a manhole designated by the Superintendent for that purpose. Discharge of truck-transported grease pit contents or industrial wastewater shall take place only after notification is made to the Superintendent and then only at the locations specified by the Superintendent. The city requires payment as hereinafter provided for treatment and disposal costs.
(2) The WWTP reserves the right to refuse permission to discharge any waste that may cause interference or upset at the WWTP or any waste that violates any provision of this section.
(3) Any person holding a valid permit and wishing to discharge to the WWTP may be required to to submit to the plant operator of the WWTP a sample of each load prior to discharge. A fee and payment schedule shall be published in the permit to cover cost of the required analysis.
(4) It shall be illegal to discharge any batch liquid waste into any manhole or other part of the public sewer system or any building sewer or other facility that discharges to the public sewer system, except at designated points of discharge specified by the Superintendent for such purpose.
(5) Any liquid waste hauler illegally discharging to the public sewer system or discharging wastewater not authorized in the permit shall be subject to immediate revocation of discharge privileges and further subject to the penalties and enforcement actions prescribed in § 52.99 of this chapter including fines and imprisonment. A suspended permittee shall immediately cease discharging any wastes to the sanitary sewer system of the city or to facilities that discharge directly or indirectly into its system. Should a suspended permittee fail to voluntarily comply with any suspension order, the Superintendent shall take such actions as are deemed necessary or appropriate to prevent or minimize damage to the WWTP and/or to protect the health and welfare of the general public.
(6) A suspended permit may be reinstated by the Superintendent upon submission of assurances satisfactory to the Superintendent that the suspended permittee will comply with this section and the rules and regulations promulgated pursuant this section plus payment of such fines or other penalties as may be levied by the WWTP. The Superintendent shall require that within fifteen (15) days after the date of such occurrence, the suspended permittee submit a written report to the WWTP detailing the nature and extent of the violation(s) including any non-permitted discharges and the measures taken by the suspended permittee to prevent any future occurrences.
(7) Waste haulers who have been granted permission to discharge to the public sewer system shall pay fees for such discharge in accordance with a fee schedule established by the Superintendent and approved by the city. The city shall establish, and from time to time may alter, a schedule of fees, rates and charges for the Domestic Waste Hauler's Permit to cover the costs of treatment and disposal of all wastes governing permit issuance, requirements, conditions, suspensions and all other matters necessary or appropriate to implement this section.
(8) Dumping hours shall be limited to 6:00 a.m. to 6:00 p.m. local time Monday through Friday, excluding recognized city holidays. Dumping after hours or on holidays may be allowed by permission only from the operator on duty at the Westside Wastewater Treatment Plant.
(9) The permittee shall complete a chain of custody report for each load of waste deposited into the city's sewer system. The information on the chain of custody report shall be recorded, and signed by an employee of the permittee or the permittee himself and shall be in duplicate on forms furnished by the city. The original copy of the chain of custody will be maintained at the Westside Wastewater Treatment Plant. A summary invoice detailing the total monthly discharges will be mailed prior to the tenth of each month. Payment will be due within two (2) weeks of receipt.
(10) Discharge of all liquid wastes allowed under this section shall take place only at the location(s) designated by the Superintendent. The designated location or manhole to be used under the Domestic Waste Hauler's Permit may be changed by the Superintendent as deemed necessary.
(11) The discharge of trucked and/or hauled wastes from industrial plating processes or radiator businesses is prohibited.
(12) Nothing in this section shall relieve waste haulers of the responsibility for compliance with the Hopkins County Health Department, state and federal regulations.
