(A) Approval by Murray Sewer System. The following described substances, materials, waters, or wastes, shall be limited in discharges to Murray Sewer System to concentration or quantities which: will not harm the sewers, wastewater treatment process, or equipment; will maintain and protect the water quality in the receiving stream; and will not otherwise endanger life, limb, public property, or constitute a nuisance. Murray Sewer System, in its sole and absolute discretion, may establish additional limitations or limitations more stringent than those established in the provisions below, if, in its opinion, more severe limitations are necessary to meet the above objectives. In forming an opinion as to the acceptability of a discharge, the Murray Sewer System shall consider such factors, including but not limited to, the quantities of subject wastes in relation to flows and velocities in the sewers, materials of construction of the sewers, nature of the wastewater treatment process employed, capacity of the water resource recovery facility, and degree of treatability of wastes in the water resource recovery facility.
(B) No person shall discharge or cause to be discharged any trucked or hauled pollutants except at designated discharge points and at such times as designated by the POTW (40 CFR 403.5(b)). Pollutants from non-domestic sources that are transported to the POTW by truck (or rail) are subject to the general pretreatment regulations and may be subject to the categorical pretreatment standards.
(1) Any person who transports septic tank, seepage pit or cesspool contents, liquid industrial wastes or other bulk liquid wastes and wishes to discharge such wastes to the public sewer system shall first have a valid septage hauler's discharge permit. All applicants for a septage hauler's discharge permit shall complete an application form, the waste hauler questionnaire, pay the appropriate fee, and receive a copy of the Murray Sewer System's requirements governing discharge into the sewers of liquid wastes from trucks. All persons receiving such permits shall agree, in writing, to abide by all applicable provisions of this chapter, and any other special provisions that may be established by the city as necessary for the proper operation and maintenance of the sewer system. In addition, any person holding a valid permit and wishing to discharge to the water resource recovery facility (WRRF), shall submit a sample at the request of the Supervisor or his designee, at the time of discharging into the WRRF. Fees for sampling and analysis will be recovered from each permit holder. Permit requirements may be obtained from the Department of Public Works and Utilities on Andrus Drive or from the Pretreatment Coordinator at 90 CC Lowry Drive, Murray, Kentucky.
(2) The POTW may require waste haulers to document the source of wastes being discharged, potentially requiring manifests which should include; general hauler information, information on the waste generator (name, address and telephone number), type of wastes collected, volumes, known or suspected pollutants, and certification that the load is not a hazardous waste. Both a POTW and hauler self-monitoring may be instituted to verify that the waste has not affected the POTW.
(3) It shall be illegal to discharge any bulk 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. 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, including fines and imprisonment.
(4) 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 city.
