(a) The admission into the public sewers of any water or waste having:
(1) A five-day BOD greater than two hundred fifty (250) parts per million by weight; or
(2) Containing more than two hundred fifty (250) parts per million by weight of suspended solids; or
(4) Flows defined as "significant industrial user."
shall be subject to the review and approval of the director, division of engineering and the director, division of sanitary sewers.
(b) Where necessary, in the opinion of the director, division of engineering or director, division of sanitary sewers, the owner shall provide, at his expense, such preliminary treatment as may be necessary to:
(1) Reduce the BOD and/or suspended solids to two hundred fifty (250) parts per million by weight; or
(2) Reduce the objectionable characteristics or constituents to within the maximum limits provided for in section 16-43; or
(3) Control the quantities and rates of discharge of such water or waste.
(c) Plans, specifications and any other pertinent information relating to proposed preliminary treatment facilities shall be submitted for the approval of the director, division of engineering and the director, division of sanitary sewers and of the urban county health department; and no construction of such facilities shall be commenced until such approvals are obtained in writing.
(d) Where preliminary treatment facilities are provided for any water or waste, they shall be maintained continuously in satisfactory and effective operation by the owner at his expense.
(e) 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 section 16-43 of this article, and which in the judgment of the director, division of sanitary sewers, may have a deleterious effect on the sewerage system, processes, equipment or receiving waters, or which otherwise create a hazard to life or constitute a public nuisance, the director, division of sanitary sewers shall require the discharger to obtain a waste water discharge permit. The director, division of sanitary sewers, upon review of the permit application, may grant the permit, reject the permit or grant with the following conditions:
(1) Require pretreatment to an acceptable condition for discharge to the public sewers;
(2) Require control over the quantities and rates of discharge; and/or
(3) Require payment to cover the added cost of handling and treating the wastes not covered by existing taxes or sewer service charges.
If the director, division of sanitary sewers permits the pre-treatment or equalization of waste flows, the design and installation of the plants and equipment shall be subject to the review and approval of the director, division of sanitary sewers, and subject to the requirements of all applicable codes, ordinances and laws.
(f) When required by the director, division of engineering and or the director, division of water quality, the owner of any property served by a building sewer carrying industrial wastes shall install a suitable control manhole and monitoring equipment 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 in accordance with plans approved by the director, division of engineering. The manhole and monitoring equipment shall be installed by the owner at his expense and shall be maintained by him so as to be safe and accessible at all times.
Sampling and measurement of the waste will be done in accordance with instructions and at a frequency specified in the users permit. Monitoring frequencies will be based on the volume and strength of waste and have been approved by the urban county government, state and EPA. All wastewater samples must be representative of the User's discharge. Wastewater monitoring and flow measurement facilities shall be properly operated, kept clean, and maintained in good working order at all times. The failure of a User to keep its monitoring facility in good working order shall not be grounds for the User to claim that sample results are unrepresentative of its discharge.
(g) All measurements, tests and analyses of the characteristics of water and waste to which reference is made in sections 16-42 through 16-44 shall be determined and performed in accordance with procedures established by the EPA pursuant to section 304(g) of the Act and contained in 40 CFR 136, as amended, and 40 CFR 261, and shall be determined at the control manhole provided for in subsection (f) of this section or upon suitable samples taken at such control manhole. In the event no special manhole has been required, the control manhole shall be considered to be the nearest downstream manhole in the public sewer to the point at which the building sewer is connected.
