(a) Requirements. Users shall provide necessary wastewater treatment as required to comply with this chapter, and shall achieve compliance with all national categorical pretreatment standards within the time limitations as specified by the Federal pretreatment regulations. Any facilities required to pretreat wastewater to a level acceptable to the POTW shall be provided, operated and maintained at the user's expense. Detailed plans showing the pretreatment facilities and operating procedures shall be submitted to the Director for review, and shall be acceptable to the City before construction of the facility. The review of such plans and operating procedures will in no way relieve the user from the responsibility of modifying the facility, as necessary, to produce an effluent acceptable to the Director under the provisions of this chapter. Any subsequent changes in the pretreatment facilities or method of operation shall be reported to and be acceptable to the Director prior to the user's initiation of the changes.
(b) Compliance Schedules. When, in the opinion of the Director, it becomes necessary for industrial users to install technology or provide additional operation and maintenance (O & M) to meet any condition of this chapter or applicable administrative order, the Director shall require the development of the shortest schedule by which the industrial user will provide this additional technology or O & M.
(1) The schedule shall contain increments of progress in the form of dates for the commencement and completion of major events. Under no circumstances shall any increment exceed nine months.
(2) Not later than fourteen days following each date in the schedule and the final date for compliance, the trial user shall submit a progress report to the Director, including, at a minimum, whether or not it complied with the increment of progress to be met on such date and, if not, the date on which it expects to comply with this increment of progress, the reason for delay, and the steps being taken to return to the schedule established.
(c) Acceptance of Pretreatment Plans. Plans, specifications and any other pertinent information relating to treatment or pretreatment facilities, holding tanks, control or neutralization equipment, or other facilities to be utilized in the treatment or control of waters and wastes, shall be submitted for acceptance by the POTW, and no construction of such facilities shall be commenced until such acceptance is obtained in writing. All plans shall be subject to the requirements of all applicable codes, ordinances and laws.
(d) Required Operation of Pretreatment Facilities. Where such facilities are provided for treatment, pretreatment, control or neutralization of waters or waste, they shall be maintained continuously in satisfactory and effective operation by the owner or user at his or her expense, and shall be subject to inspection by the Director every six to twelve months, or more often if deemed necessary by the Director and established in Chapter 923 of these Codified Ordinances. The user shall maintain operating records and shall submit to the POTW a monthly report of the character of the influent and effluent as may be prescribed by the Director to show performance of the treatment facilities.
(1) A bypass of the treatment system is prohibited unless all of the following conditions are met:
A. The bypass was unavoidable to prevent loss of life, personal injury or severe property damage;
B. There was no feasible alternative to the bypass, including the use of auxiliary treatment of the wastewater; and
C. The industrial user properly notified and obtained the approval of the Director, or a bona fide emergency occurs and the user is unable to contact the Director.
(2) Industrial users shall provide immediate notice to the Director upon discovery of a bypass.
(3) The Director may allow a bypass to occur, which bypass does not cause pretreatment standards or requirements to be violated, if it is for essential maintenance to ensure efficient operation of the user's treatment system. Industrial users anticipating a bypass shall submit notice to and obtain the approval of the Director at least ten days in advance of such bypass.
(4) A written submission shall also be provided within five days of the time the user becomes aware of the bypass. The written submission shall contain a description of the bypass and its cause, the duration of the bypass (including exact dates and times and, if the bypass has not been corrected, the anticipated time it is expected to continue), and the steps taken or planned to reduce, eliminate and prevent recurrence of the bypass. The Director may waive the written report on a caseby-case basis if the oral report has been received within twenty-four hours.
