California’s newer groundwater regulatory structure, the Sustainable Groundwater Management Act of 2014 (“SGMA”), was signed by Governor Edmund G. Brown Jr. on September 16, 2014. The State Water Resources Control Board (“SWRCB”) is the enforcement agency for SGMA. SGMA requires the SWRCB to establish a schedule of fees sufficient to recover the costs incurred by

On October 18, 2016, the Department of Water Resources (DWR) released its final modifications to California’s groundwater basin boundaries in response to the emergency regulations adopted by DWR last October.  The basin boundary changes were implemented under the Sustainable Groundwater Management Act (SGMA) to provide flexibility to local public agencies to bring their groundwater basins

With Senate Bill 1262 (“SB 1262”), California’s Sustainable Groundwater Management Act (“SGMA”) has become firmly rooted into the State’s water supply planning laws. Specifically, SB 1262 amends the Water Supply Assessment statute (commonly referred to as “SB 610”) and the Written Verification statute (commonly referred to as “SB 221”).

Background – SB 610 & SB 221

As way of background, SB 610 and SB 221 operate to help cities and counties make informed land use decisions by providing the local governments with information on water supply availability. SB 610 and SB 221 are companion laws that promote more collaborative planning between local water suppliers and cities and counties.  Both statutes require detailed information regarding water availability to be provided to the city and county decision-makers prior to approval of specified large development projects.

Under SB 610, Water Supply Assessments must be provided to local governments for certain projects subject to the California Environmental Quality Act (“CEQA”). The Water Supply Assessment must analyze whether projected water supplies are sufficient to meet the projected water demand of the proposed development project.  Similarly, under SB 221, approval by a city or county of certain subdivisions requires an affirmative Written Verification of sufficient water supply.

Stanford University released a study this week stating that California has three times more useable groundwater located in deep aquifers than previously estimated.  This might come as welcome news to a state that continues to suffer through a historic drought.  The researchers found that fresh groundwater was available at depths previously thought to be too deep to contain fresh water.

At the outset, readers should note that “freshwater” and “drinking water” are terms of art having regulatory and legal distinctions, and ultimately making a difference for the public welfare. The definition of freshwater varies depending on the state or federal agency; however, freshwater is generally defined as having less than 3,000 mg/L of total dissolved solids (“TDS”).  Underground Sources of Drinking Water (“USDW” or “drinking water”) as defined by the Environmental Protection Agency include groundwater aquifers with less than 10,000 mg/L TDS.  For reference, seawater contains approximately 35,000 mg/L TDS.

Historically, California’s fresh groundwater supply was thought to be limited to water found above 1,000 feet. However, the researchers determined that the mean base of fresh water (“BFW”) in five Central Valley counties (Kern, Fresno, Solano, Colusa, and Yolo) ranged from 1,345 feet (Colusa) to 2,204 feet (Kern).  The base of drinking water is considerably deeper than the freshwater.  Specifically, USDW can be found in Kern and Los Angeles Counties at depths deeper than 8,200 feet.

California has moved one step closer to implementing the Sustainable Groundwater Management Act (“SGMA”), California’s landmark groundwater legislation. On Wednesday, May 18, the California Water Commission adopted a set of regulations that will govern the creation of groundwater sustainability plans (“GSPs”) by local Groundwater Sustainability Agencies (“GSAs”). The emergency regulations, developed by the Department of Water Resources (“DWR”), take effect in June.

The new regulations will have some real impacts on GSAs and their implementation of SGMA. The most significant requirements include:
