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:

Picture1.png

 

• Detailed in CCR Title 23 § 350 - §358.4

• Administrative Information

• Basin Setting

– Hydrogeologic Conceptual Model

– Groundwater Condition

– Water budget

– Management Areas

 

• Sustainable Management Criteria

– Sustainability Goal

– Undesirable Results

– Minimum Thresholds

– Measurable Objectives

• Monitoring Network

• Projects and Management Actions

  

Phases of Groundwater Sustainability Plan Development and Implementation

  • Phase 1: GSA Formation 
  • Phase 2: GSP Preparation and Submission 
  • Phase 3: GSP Review and Evaluation 
  • Phase 4: Implementation and Reporting 

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).

2020

A Technical Advisory Committee (TAC) meeting was held on November 11, 2020 to finalize the Hydrogeologic Conceptual Model technical memorandum and prove update on East Bay Plain Subbasin groundwater model development.

As part of completing the additional work funded by the Proposition 68 grant agreement, the Request for Proposal (RFP) to implement East Bay Plain Subbasin Characterization Project was advertised on July 16, 2020. The scope of work includes conducting groundwater pumping tests, completing isotopic sampling of groundwater and streams, and installing 12 monitoring wells. The RFP is listed under the Resource Documents below. 

EBMUD executed a Proposition 68 grant agreement amendment with the Department of Water Resources on May 15, 2020, which provides $758,467 of additional funding for EBMUD and the City of Hayward to complete groundwater pumping tests, conduct isotopic sampling of groundwater and streams, install 12 monitoring wells, and develop a data management system. The executed amendment is available in the list of Resource Documents below.

A virtual Technical Advisory Committee (TAC) meeting was held on May 4, 2020. The TAC completed the following tasks:

  • Provide overview of completed Technical Memorandums
  • Address TAC members’ comments
  • TM 4.1 Summary of Findings & Comments 
  • TM 4.3 Summary of Findings & Comments

A Technical Advisory Committee (TAC) meeting was held on May 4, 2020 to discuss completed data gap analysis and model selection tasks. Comments from members of TAC were addressed during and after the meeting. Completed technical memorandums are available in the list of Resource Documents below.

The Department of Water Resources (DWR) released the draft recommended funding awards lists for the Sustainable Groundwater Management (SGM) Grant Program (Prop 68 grant) on January 24, 2020. The EBMUD and the City of Hayward’s East Bay Plain Subbasin Characterization and Data Management application was conditionally recommended for grant funding for the amount of $758,467.

DWR Logo_4 inch_Color_071618.jpgDWR completed the 2018 SGMA Basin Prioritization process to reassess the priority of the groundwater basins following the 2016 basin boundary modifications, as required by the Water Code. The final results are published on January 4, 2019. From this process, the East Bay Plain Subbasin was determined as a Medium Priority Subbasin.

The following is the link to DWR’s basin prioritization page:
