PRETREATMENT PROVISIONS
(A) Introduction. This subchapter sets forth uniform requirements for direct and indirect contributors into the wastewater collection and treatment system and enables the city to comply with all applicable state and federal pretreatment regulations (40 CFR Part 403).
(B) Federal standards supersede. Any existing or new federal categorical pretreatment standards shall immediately supersede the limitations imposed under this chapter if more stringent. In such a case, the Superintendent shall notify all affected users of the applicable reporting requirements under 40 CFR 403.12.
(C) Modification of federal pretreatment standards.
(1) Where the city's wastewater treatment system achieves consistent removal of pollutants limited by federal pretreatment standards, the city may apply to the approval authority for modification of specific limits in the federal pretreatment standards. CONSISTENT REMOVAL shall mean reduction in the amount of a pollutant or alteration of the nature of the pollutant by the wastewater treatment system to a less toxic or harmless state in the effluent.
(2) The city reserves the right to establish as described in § 51.062(P), more stringent limitations or requirements on discharges to the wastewater disposal system if deemed necessary.
(Ord. 622, passed 3-4-85; Am. Ord. 704, passed 3-12-91; Am. Ord. 727, passed 4-29-91; Am. Ord. 1074, passed 9-27-21)
No user shall ever 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 in the federal categorical pretreatment standards, or in any other pollutant-specific limitation developed by the city or state. (Exception is made when applicable to dilution to meet the pH requirement.)

Each user shall provide protection from accidental discharge of prohibited materials or other substances regulated by this chapter and operational upset of pretreatment facilities. Facilities to prevent accidental discharge of prohibited materials and operational upsets shall be provided and maintained at the owner's or user's own cost and expense. Detailed plans showing facilities and operating procedures to provide this protection shall be submitted to the city for review, and shall be approved by the city before construction of the facility. All existing users shall complete such a plan by 180 days after the effective date of this chapter. No user who commences contribution to the POTW after the effective date of this chapter shall be permitted to introduce pollutants into the system until accidental discharge and operational upset procedures have been approved by the city. Review and approval of such plans and operating procedures shall not relieve the user from the responsibility to modify the user's facility as necessary to meet the requirements of this chapter. Copies of the user's spill prevention control and countermeasure (SPCC) plan and the pollution incidence prevention plan (PIPP) shall be filed with the city.
(A) Immediate notice. In the case of an accidental discharge or operational upset, it is the responsibility of the user to immediately telephone and notify the POTW of the incident. The notification shall include location of discharge, type of waste, concentration and volume, and corrective actions.
(B) Written notice. Within five days following an accidental discharge or operational upset, the user shall submit to the Manager a detailed written report describing the cause of the discharge and the measures to be taken by the user to prevent similar future occurrences. Such notification shall not relieve the user of any expense, loss, damage, or other liability which may be incurred as a result of damage to the POTW, fish kills, or any other damage to person or property; nor shall such notification relieve the user of any fines, civil penalties, or other liability which may be imposed by this chapter or other applicable law.
(C) Notice to employees. 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 dangerous discharge. Employers shall insure that all employees who may cause or suffer such a dangerous discharge to occur are advised of the emergency notification procedure.
