For Municipal Staff Only

Rosemarie Gaglione, Director, Public Works

This page is for use by staff from municipalities responsible for implementing Phase II Municipal (MS4) Stormwater Permit requirements. The 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. ASC Meeting Schedule

Further public relations, permit compliance support, monitoring, reporting, and planning efforts are provided in the MCSTOPPP 2015-2016 Accomplishment Summary.


E.1 Requirements from Previous Permit still applicable

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 requires you 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 has completed your preliminary jurisdictional maps and uploaded them for you, and provided you with a 13383 Response Letter Template. The template response letter must be signed by your LRP and submitted through SMARTS by September 1, 2017!
