(A) A user may be required by the Director to install, maintain and use wastewater pretreatment devices or systems before discharge to the city's sewer system. Pretreatment may be necessary to restrict or prevent the discharge of certain waste constituents, to distribute more equally over a longer time period any peak discharges of industrial wastewaters, or to accomplish any pretreatment results required by this chapter (40 CFR § 403.8(f)(1)(iii)).
(B) Pretreatment facilities as required by the Director must be maintained in good working order and operated as efficiently as possible at the expense of the discharger, and are subject to the requirement of this chapter and all other applicable codes and laws.
(C) Where pretreatment or flow equalization before discharge into the city's sewer system is required, plans, specifications and other pertinent data or information relating to the pretreatment or flow control must first be submitted to the Director for approval. The approval must not exempt the discharger of said facilities from compliance with any applicable rule or ordinance of any other governmental authority. Any alterations or additions to the pretreatment facilities must not be made without due notice to the Director for prior review and approval.
(D) All federal pretreatment standards applicable to local industry which specify quantities or concentrations of pollutants that may be discharged by a specific industrial subcategory will be enforced by the city as required in §§ 309(e) and (f) of the Clean Water Act, 33 U.S.C. §§ 1319(e) and (f). Compliance by existing industrial users with categorical pretreatment standards must be within three years of the date the standard is promulgated unless a shorter time is specified by the EPA.
(E) All domestic wastewaters including, without limitation, those from restrooms, showers and drinking fountains must be kept separate from industrial wastewaters until the industrial wastewaters have passed through any required pretreatment and/or monitoring device or system.
(F) The following conditions must apply to any compliance schedule required by this chapter or the control authority:
(1) The schedule must contain progress increments in the form of dates for the commencement and completion of major events leading to the construction and operation of additional pretreatment required for the user to meet the applicable pretreatment standards (such events include, without limitation, hiring an engineer, completing preliminary and final plans, executing contracts for major components, commencing and completing construction, beginning and conducting routine operation);
(2) No increment referred to above must exceed nine months;
(3) The user must submit a progress report to the control authority no later than 14 days following each date in the schedule and the final date of compliance including, as a minimum, whether or not it complied with the increment of progress, the reason for any delay, and, if appropriate, the steps being taken by the user to return to the established schedule; and
(4) In no event must more than nine months elapse between such progress reports to the control authority.
(5) No compliance schedule must exceed 18 months.
