Sustainable Groundwater Management Act

In stakeholders5.pngSeptember 2014, Governor Brown signed into law three bills collectively known as the Sustainable Groundwater Management Act (SGMA). SGMA creates a statewide framework for sustainable, local groundwater management in California.

SGMA requires eligible local agencies overlying certain basins to form Groundwater Sustainability Agencies (GSAs). GSAs are required to develop Groundwater Sustainability Plans (GSP) to make basins sustainable within 20 years of implementation.

What is Sustainable Groundwater Management?

Sustainable groundwater management is the management and use of groundwater in a manner that can be maintained now and into the future without causing undesirable results.

 

Groundwater Sustainablity Plan (GSP)

A GSP is a plan to implement the sustainable groundwater management of the local basins. A typical GSP will include the following components:

East Bay Plain Subbasin and EBMUD

EBMUD’s service area overlies a significant portion of the East Bay Plan Subbasin, which is part of the larger Santa Clara Valley Basin. Following notice in local newspapers and a public hearing, EBMUD’s Board of Directors adopted a resolution to become the GSA for the entire portion of the basin that underlies EBMUD’s service area in 2016. In November 2016, after a 90 day comment period, EBMUD became the exclusive GSA with regulatory and management responsibilities for that portion of the basin (DWR Basin Number 2-009.04).
