The Basics Permit Overview
Goal of Program • Reduce pollutants in discharges from the MS4 • Change Behavior • Permit Compliance
Requirement Reduce pollutants in storm water discharges to the Maximum Extent Practicable (MEP) by implementing a Storm Water Management Program (SWMP)
MEP • Technology standard • Dynamic
SWMP • 6 Minimum Control Measures as a basis for a SWMP • BMPs to address 6 Minimum Control Measures • Measurable Goals for each BMP • Time schedules for each Measurable Goal
Public Education Requirements • Educate the public on • The impacts of storm water • The steps the public can take to reduce pollutants in storm water runoff
Public Participation Requirements • Comply with State and local public notice requirements • Allow the public to review and comment on the permit and SWMP • Involve the public in the implementation of SWMP
Illicit Discharge Detection and Elimination Requirements • Storm sewer system map • An ordinance prohibiting non-storm water discharges • Plan to detect and address non-storm water discharges • Educate the public on the hazards of illicit discharges
Construction Site Control Requirements • An enforceable ordinance to require erosion and sediment controls at construction sites • MS4 must require construction site operators to use BMPs • Site plan and BMP review • Public comments/complaints procedures • Site inspections and enforcement procedures
Post-Construction Management Requirements • An ordinance requiring long term BMPs • On-going maintenance of BMPs
Pollution Prevention/Good Housekeeping Requirements • Examine municipal activities that have the potential to cause pollution in storm water • Implement BMPs to reduce that potential • Train employees
Annual Reports • Have you done what you said you would do? • In light of water quality, have you seen noticeable changes? • Are the BMPs you chose effective? • Are they implemented well? • Improvements? • Reporting form
Supplemental Provisions • Communities over 50,000 or subject to high growth (>25%/10 yrs) • Comply with Receiving Water Limitations • Incorporate Design Standards
Receiving Water Limitations • Water Quality Standard • may require more than MEP • Objectives (http://www.swrcb.ca.gov/) • Basin Plans • California Toxics Rule • Statewide Water Quality Control Plan • Iterative Approach • Ex: San Diego - trash (floatables) in Chollas and Paleta Creeks
Design Standards • Post Construction Requirements
