§ 25-123. Modification of federal categorical pretreatment standards.
Latest version.
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 nature
of the pollutant by the wastewater treatment system to a less toxic or harmless state
in the effluent, as determined according to the procedures set forth in 40 CFR Part
403, section 403.7 ("General Pretreatment Regulations for Existing and New Sources
of Pollution."). The city may then modify pollutant discharge limits in the federal
pretreatment standards if the requirements contained in 40 CFR Part 403, section 403.7
are fulfilled and prior approval is obtained from the approval authority.
