Where the city POTW treatment plant achieves consistent removal of pollutants limited by pretreatment standards, the city may, at the request of a user, apply to the Approval Authority for modification of specific limits in the pretreatment standards. "Consistent removal" shall mean the 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 which is achieved by the system in 95 percent of the samples taken measured according to the procedures set forth in section 40 CFR 403.7(c)(2). The city may then modify pollutant discharge limits and the pretreatment standards if the requirements contained in 40 CFR 403.7 are fulfilled and prior approval from the Approval Authority is obtained. Any user requesting application for modification shall reimburse the city for all costs of testing and data compilation required by 40 CFR 403.7.
