From:  Central Valley Regional Water Quality Control Board (CVRWQCB)

On 20 October 2011, the US Environmental Protection Agency approved the Delta Mercury Control Program (new fish tissue objectives, and TMDLs for the Delta and Yolo Bypass).  The EPA approval date establishes the Effective Date of the Basin Plan amendment.

The Basin Plan amendment contains actions and schedules based on the Effective Date of 20 October 2011. This includes requirements for the Phase 1 methylmercury Control Studies and other requirements for specific mercury/methylmercury sources.

The entire Basin Plan amendment is at:

Within two weeks, CVRWQCB will be revising the Basin Plan amendment on the web page to reflect the actual dates.  CVRWQCB will be holding a stakeholder meeting on 10 November to discuss the schedule and the Phase 1 Control Studies.
