(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.
