STORMWATER REGULATORS
Clean Water Act (CWA)authorization to regulate“point source” discharges
MS4General Permit• Localities&StateEntitieswithinurbanized areas
• MinimumControl Measures• SpecialConditionsfor TMDLs
Compliance &Enforcement
MS4GENERAL PERMIT
Requires the operator to:“ … develop, implement, and enforce a MS4 Program designedto reduce the discharge of pollutants from the regulated smallMS4 to the maximum extent practicable …”
Maximum Extent Practicable (MEP)– Ensurescompliancetowaterqualitystandardsin theMS4 Program:o AddressesMinimumControlMeasureswithBestManagement
