4. California Stormwater Regulations  Municipal Storm Drain Systems Are Regulated  Federal Clean Water Act  National Pollutant Discharge Elimination System Municipal Stormwater Permits Reduce & prevent the discharge of pollutants Stormwater Management Plans

5. Stormwater Regulatory Program Continued  State Water Resources Control Board (SWRCB)  San Francisco Bay Regional Water Quality Control Board  SWRCB General Stormwater Permits  Municipal Program Phase II communities – Marin, Napa, Sonoma, Solano  Construction Program sites disturbing > 1 acre  Industrial Program Boatyards, Wineries, Landfills, Airports…  SF Bay Regional Water Board  Regulatory oversight of statewide general permits  Issues Individual & Regional NPDES Stormwater Permits Municipal Regional Stormwater Permit – Phase I Communities Contra Costa, Alameda, Santa Clara, San Mateo, Vallejo, Fairfield Suisun

6. Intro: Statewide Phase II Stormwater Permit  Affects municipalities in Marin, Napa, Sonoma & Solano (less than 100,000 population)  Covered by 1 st version of the Phase II Permit now  New draft permit released June 7, 2011  More prescriptive  More reporting  More expensive tighter regulations  View permit SWRCB website: http://www.swrcb.ca.gov/water_issues/programs/stormw ater/phase_ii_municipal.shtml

7. Re-issued Permit: One Size Fits All Approach  Prescriptive statewide permit  Stormwater Management Plans no longer required  Current Permit more flexible  Current Stormwater Management Plans developed locally  Some flexibility in new Draft Phase II Permit  Permittees (Municipal Stormwater Programs) can evaluate existing program and update as necessary  Can obtain approval from Regional Water Board to implement existing program

8. Timeline  August 8, 2011: Comments due by noon  November 2011: Water Board Hearing  January 2012: Adoption  May 15, 2012: Effective Date of Re-issued Permit  July 15, 2012: Notice of Intent by Permittee

11. Draft Permit Provisions Continued  Discharge Prohibitions  Program Management  Six Minimum Control Measures  More Prescriptive  New Components  Industrial/Commercial Program  Trash Reduction Program  Water Quality Monitoring and Assessment  Program Effectiveness  Total Maximum Daily Loads

12. Discharge Prohibitions  Not new – discharges of anything except clean stormwater prohibited  New: control incidental runoff  Prohibit unintended discharges of small amounts of potable and recycled water i.e. from sprinkler over-spray Require correction in 72 hours Comment Needed!

13. Program Management Element  Ensure Adequate Resources to Comply with Order  Enforcement Response Plan  detailed tracking to reduce recidivism Comment Needed!

14. Public Outreach and Education  Develop Public Education Strategy  Community-Based Social Marketing (CBSM) Research-based public outreach approach More expensive  Measure behavior change  Target Audiences School-age children Industrial/Commercial Businesses Construction Industry Comment Needed!

15. Illicit Discharge Detection and Elimination  GIS Mapping  Priority Areas -20% of Urbanized Areas  Dry Weather Field Screening and Analytical Monitoring (1/yr)  Spill Response Plan Comment Needed!

16. Construction Site Storm Water Runoff Control  Inventory construction sites with grading  Inspections  Sites >1acre frequency range within 48 hours of rain event at least monthly.  Follow Standard Operating Procedures  All phases of construction  Specialized Training for Plan Reviewer and Inspectors  Track & report inspections and enforcement Comment Needed!

17. Pollution Prevention / Good Housekeeping (Maintenance)  Facility inventory and mapping  Facility inspections & Stormwater Pollution Prevention Plans  Storm drain system assessment and maintenance  Operations & maintenance, training & detailed reporting Comment Needed!

18. Post-Construction Stormwater Management Program  Municipalities with population <25,000  Projects that Disturb > 1 acre  Require stormwater treatment and control from development

22. Receiving Water Monitoring  Permittees with population > 25,000  Develop and Implement Water Quality Monitoring Plan  Receiving Water Monitoring  Follow-up Analysis and Actions Comment Needed!

23. Program Effectiveness Assessment  Develop Program Effectiveness and Improvement Plan  Best Management Practice Condition Assessment  Watershed Pollutant Load Quantification Comment Needed!

24. Total Maximum Daily Loads  Comply with Applicable TMDLs  Richardson Bay Pathogen TMDL  Report Annually TMDL Implementation

25. Areas of Concern – Comments Needed  60-day comment period too short  Request opportunity to respond to final draft permit  Possible unfunded mandates in draft permit  Reduce cost of permit implementation by reducing reporting and removing requirements that are not cost-effective due to Proposition 218 limitations  Municipalities may face state fines and third party lawsuits  The permit creates new compliance burdens on development and local businesses
