[Amended 11-18-2013 by Ord. No. 1563]
Users shall provide wastewater treatment as necessary to comply with this chapter and shall achieve compliance with all categorical pretreatment standards, local limits, and the prohibitions set out in § 553-18 of this chapter within the time limitations specified by the EPA, the state, or the Director, whichever is more stringent. Any facilities necessary for compliance shall be provided, operated, and maintained at the user's expense. Detailed written plans describing such facilities and operating procedures shall be submitted to the Director for review and acceptance before such facilities are constructed. The review of such plans and operating procedures shall in no way relieve the user from the responsibility of modifying such facilities as necessary to produce a discharge acceptable to the Director under the provisions of this chapter.
Whenever he deems it necessary, the Director may require users to restrict their discharge during peak flow periods, designate that certain wastewater be discharged only into specific sewers, relocate and/or consolidate points of discharge, separate sewage waste streams from industrial waste streams, and impose such other conditions as may be necessary to protect the POTW and determine the user's compliance with the requirements of this chapter.
The Director may require any persons discharging into the POTW to install and maintain, on their property and at their expense, a suitable storage and flow control facility to ensure equalization of flow. A wastewater discharge permit may be issued solely for flow equalization.
Grease, oil and sand interceptors shall be provided when, in the opinion of the Director, they are necessary for the proper handling of wastewater containing excessive amounts of grease and oil or sand, except that such interceptors may not be required for residential users. All interception units shall be of type and capacity approved in writing by the Director and shall be so located as to be easily accessible for cleaning and inspection. Such interceptors shall be inspected, cleaned, and repaired regularly, as needed, by the users at their expense.
[Amended 11-18-2013 by Ord. No. 1563]
At least once every two years, the Director shall evaluate whether each significant industrial user needs an accidental discharge/slug control plan. The Director may require any user to develop, submit for approval, and implement such a plan. Alternatively, the Director may develop such a plan for any user. An accidental discharge/slug control plan shall address, at a minimum, the following:
Description of discharge practices, including nonroutine batch discharges;
Description of stored chemicals;
Procedures for immediately notifying the Director of any accidental or slug discharge as required by § 553-47 of this chapter; and
Procedures to prevent adverse impact from any accidental or slug discharge. Such procedures shall include, but are not limited to, inspection and maintenance of storage areas, handling and transfer of materials, loading and unloading operations, control of plant site runoff, worker training, building of containment structures or equipment, measures for containing toxic organic pollutants, including solvents, and/or measures and equipment for emergency response.
Septic tank waste, generated only in the City, may be introduced into the POTW only at locations designated in writing by the Director and at such times as are established in writing by the Director. The introduction of such wastes shall not violate Article III of this chapter or any other requirements established by the City. The Director may require septic waste haulers to obtain wastewater discharge permits.
