(A) National categorical pretreatment standards. National categorical pretreatment standards promulgated by the U.S. Environmental Protection Agency (EPA) pursuant to the Act shall be met by all users which are subject to such standards in any instance where they are more stringent than the limitations in this subchapter.
(B) State requirements. State requirements and limitations on discharges shall be met by all users which are subject to such standards in any instance in which they are more stringent than federal requirements and limitations or those in this or any other applicable chapter.
(C) City's right of revision. The city reserves the right to establish by ordinance more stringent limitations or requirements on discharges to the wastewater disposal system if deemed necessary to comply with the objectives presented in § 52.090.
(D) Dilution. No user shall increase the use of process water or in any way attempt to dilute a discharge as a partial or complete substitute for adequate treatment to achieve compliance with the limitations contained herein, contained in the national categorical pretreatment standards or contained in any state requirements.
(E) Accidental discharges.
(1) Each user shall provide protection from accidental discharge of prohibited materials or other substances regulated by this chapter. Where necessary, facilities to prevent accidental discharge of prohibited materials shall be provided and maintained at the owner or user's own cost and expense. Detailed plans showing facilities and operating procedure to provide this protection shall be submitted to the Director for review and shall be approved by the Director before construction of the facility.
(2) Review and approval of such plans and operating procedures shall not relieve the industrial user from the responsibility to modify the user's facility as necessary to meet the requirements of this chapter. Users shall notify the Director immediately upon having a slug or accidental discharge of substances or wastewater in violation of this chapter in order to enable countermeasures to be taken by the Director to minimize damage to the wastewater disposal system and the receiving waters.
(3) The notification will not relieve users of liability for any expense, loss or damage to the wastewater disposal system or treatment process or for any fines imposed on the city on account thereof under any state or federal law. A notice shall be permanently posted on the user's bulletin board or other prominent place advising employees whom to call in the event of a slug or accidental discharge. Employers shall ensure that all employees who may cause or discover such a discharge are advised of the emergency notification procedure.

The Director may require that any person discharging or proposing to discharge wastewater to the wastewater disposal system file a periodic discharge report. The discharge report may include but not be limited to nature of process, rates of flow, mass discharge rate, raw material and production quantities, hours of operation, number and classification of employees, compliance status with any state or federal pretreatment standards or other information which relates to the generation of waste, including wastewater constituents and concentrations in the wastewater discharge. The reports may also include sludge disposal practices and the chemical constituents and quantity of liquid or gaseous materials stored on site, even though they may not normally be discharged. At a minimum, a summary of such data indicating each industrial user's compliance with this subchapter shall be prepared quarterly and submitted to the Director. In addition to discharge reports, the Director may require information in the form of wastewater discharge permit applications, self-monitoring reports and compliance schedules.
(Ord. 297, passed 3-1-2022)
