To the extent practicable, municipalities shall provide permit conditions for storm water discharges associated with industrial activities that are consistent with any permits issued pursuant to the National Pollution Discharge Elimination System (NPDES), unless the discharge contains hazardous substances in excess of reporting quantities, or the facility and the municipality are not in compliance with applicable provisions of the NPDES permits issued to them for storm water, or the discharge materially affects the municipal storm water facilities through either the quantity of wastewater or its contamination.
