Municipal Staff

Stormwater Compliance Tools And Resources

This page is for use by municipal staff responsible for implementing Phase II Municipal (MS4) Stormwater Permit requirements. The current Phase II Permit became effective as of July 1, 2013.

To assist municipalities in implementing various sections of the Phase II Permit, MCSTOPPP will provide updates and implementation plans and tools in the panels that follow, as well as at the Agency Staff Committee (ASC) Meetings. Regular meetings are held the first Wednesday of every month from 1:30pm – 3:00pm.

Further public relations, permit compliance support, monitoring, reporting, and planning efforts are provided in the MCSTOPPP 2021-2022 TMDL-PEAIP Report.

E.1 Applicable Previous Permit Requirements

For the previous 2003 Phase II permit, each permittee was required to implement all of the Performance Standards from MCSTOPPP’s Stormwater Management Plan (Action Plan 2010). MCSTOPPP has incorporated the majority of the Performance Standards into new MCSTOPPP tools and documents that meet the new 2013 Phase II permit requirements. To comply with the remaining previous permit requirements you must:

  • Implement the applicable BMPs in the MCSTOPPP Field O&M Activities BMPs Guidelines
  • Implement your current SWPPP at your Corporation Yard
  • Document the amount of litter removed from areas targeted for litter removal (monthly)
  • Provide an adequate number of litter receptacles in commercial and other litter source areas, and maintain receptacles to prevent/minimize spillage
E.5 Separate Implementing Entity

MCSTOPPP acts as a Separate Implementing Entity (SIE) to meet permit obligations on behalf of all of the municipalities and the county. This work is conducted through a Joint Exercise of Powers Agreement (JEPA) between the Marin County Flood Control and Water Conservation District and the MCSTOPPP member agencies.

Marin County Stormwater Resource Plan

The Marin County Stormwater Resource Plan Functionally Equivalent Document (Marin SWRP) was completed in September 2017 along with a database (Appendix E) of potential projects. The list of projects will be reviewed and updated on at least an annual basis. The final documents are listed below.

Trash Reduction Requirements

The 13383 letters from the State Water Resources Control Board were received by each municipality and the county on June 2, 2017. The Order required each permittee to select one of two available compliance tracks (Track 1 and Track 2), and to submit a letter indicating the choice, along with preliminary jurisdictional maps by September 1, 2017.

MCSTOPPP provided a 13383 Response Letter Template and completed preliminary jurisdictional maps for each municipality, and all municipalities had their LRP sign and upload the letters to SMARTS along with their map prior to the deadline.
