Sustainable Groundwater Management Act


The Sustainable Groundwater Management Act is a three-bill package that passed the California state legislature and was signed into California state law by Governor Jerry Brown in September 2014. Its purpose is to ensure better local and regional management of groundwater use and it seeks to have a sustainable groundwater management in California by 2042. It emphasizes local management and formed groundwater sustainability agencies from local and regional authorities.
Proposition 1 provides $100 million to financially support sustainable groundwater management as well as cleanup and storage.

Background

Groundwater in California is used by 85% of the population, mostly used by the agriculture industry as the main water source for crops. For years, groundwater use has been poorly managed and under-regulated to a point where the state is facing major depletion.
Groundwater is particularly crucial in California because the dearth of surface water means that it supplies between one-third and two-thirds of the state's freshwater supply, depending on climatic conditions. It is being pumped in excess of the natural rate of replenishment, which in return is lowering the groundwater table, a phenomenon called "overdraft" that can cause severe land subsidence.
In 1980, the Department of Water Resources noted that of California's 450 groundwater basins, 40 were in overdraft and 11 were identified as being in "critical" conditions and groundwater levels have dropped to 50 feet below historic levels—up to 100 feet below in the San Joaquin Valley. Knowing how much groundwater is being taken out and used is difficult because there is no reporting requirement. There are a few exceptions that require basins operating under government regulation and special state legislation. Managing groundwater is also challenging because it does not adhere to property lines and freely moves underground. With few incentives and fewer regulations to conserve groundwater, California farms have planted higher-value crops that require year-round irrigation and have drilled deeper wells to retrieve groundwater from sinking aquifers. Drought conditions in California are only pushing for a more heavily regulated groundwater management to be implemented now.

Legislation

The Sustainable Groundwater Management Act consists of three bills. It was primarily authored by California State Assemblymember Roger Dickinson and State Senator Fran Pavley.

AB 1739

AB 1739 gives the California Department of Water Resources or a groundwater sustainability agency the authority to establish fees and offer support to "entities that extract or use groundwater to promote water conservation and protect groundwater resources". GSAs are locally controlled organizations in California's high- and medium-priority groundwater basins and are responsible for preparing a groundwater sustainability plan, implementing SGMA, and coordinating with neighbors.
AB 1739 also requires DWR to organize and publish an online report with estimates of groundwater replenishment and best practices. GSAs are required to submit a groundwater sustainability plan to the DWR for review. DWR must determine regulations to evaluate, implement, and coordinate GSPs based on conditions of "hydrology, water demand, regulatory restrictions that affect the availability of surface water, and unreliability of, or reductions in, surface water deliveries to the agency or water users in the basin, and impact of those conditions on achieving sustainability and shall include the historic average reliability and deliveries of surface water to the agency or water users in the basin".

SB 1319

Approved by Governor Jerry Brown on September 16, 2014, Senator Pavley's SB 1319 authorized local agencies to implement a groundwater plan. Management of groundwater prior to the Sustainable Groundwater Management Act was unregulated and voluntary for the various agencies using groundwater ranging from special districts under authority granted from the state, city, and county ordinances and court adjudicated basins. Senate bill 1319 requires for the groundwater management plans to follow specific and include components that the state deems as sustainable for the specific groundwater basin and aligns with the SGMA timeline. If an agency was seeking funds from the Department of Water Resources for a project regarding groundwater or groundwater quality, they too have to abide to specific requirements such as preparing and implementing a groundwater management plan. Managing groundwater is a challenging task, one that has been addressed by the SGMA. Groundwater is out of sight which makes it difficult to monitor, especially when the groundwater basins boundaries reach across multiple agencies and users. Pumping unregulated and mismanaged groundwater can lead to a "tragedy of the commons", with each user maximizing the resource for their own gain with little responsibility for the depleting aquifer. The SGMA set basin boundaries based on a 2003 Department of Water Resources report. The report broke it down into there being 431 current groundwater basins in California that have been delineated, of these basins 24 are subdivided into 108 basins to total 515 basins in all. The report based these boundaries off the alluvial sediments found using geographic maps. Groundwater is difficult to manage due to it being unseen and not neatly aligned with the jurisdiction of these set basin boundaries. The SGMA calls for the GSAs to communicate and work with the overlapping groundwater uses and allow for a governance of the basin through different means. These can include a memorandum of agreement between the multiple parties or through a legal joint agreement. By these agreements the groundwater basin can be regulated by multiple GSAs or just by one agency.

SB 1168

The California Constitution and SB 1168 require that any use of the groundwater be both reasonable and beneficial. California has a history of complex water rights, in which the Reasonable and Beneficial Use Doctrine is a key tenet. The doctrine was originally developed for riparian landowners and surface water management, but SB 1168 applied it to the context of groundwater and the SGMA, stating that any use of groundwater has to be sustainably managed for long-term reliability and multiple economic, social, and environmental benefits for future uses.
Specifically, SB 1168 gives GSAs the authority to:
It requires the Department of Water Resources to:

SB 13 amendments

Since the collection of bills that make up SGMA were complex, some minor changes were made in SB 13 pertaining to GSA formation. Prior to SB 13, existing law required that each high- and medium-priority groundwater basins be managed after implementing a groundwater sustainability plan and subjected reporting requirements to the State Water Resources Control Board. SB 13 changed DWR's role with respect to reviewing, posting, and tracking GSA formation notices. Changes include notifying reviews, GSA boundaries which overlap, and service area boundaries.

Bill overview

Key definitions

Key terms in the SGMA are defined as follows:
A GSA is a local agency that implements the SGMA as the primary entity responsible for reaching groundwater sustainability. It is required to develop and implement a groundwater sustainability plan to consider the interests of all of its stakeholders.
Any local agency or combinations thereof may form a GSA for the basin in which they overlap. A "local agency" refers to a local public agency that has water supply, management, and land use obligations within the groundwater basin. The SGMA determined 43 high-priority groundwater basins and 84 medium-priority groundwater basins, totaling 127 basins accounting for 96% of California's groundwater. These basins must adopt GSPs by 2020 or 2022 and have until 2040 or 2042 to attain sustainability. A local agency can decide not to form a GSA and submit an alternative proposal to DWR if they believe the alternative will meet the objectives and long-term goals of the SGMA. The DWR is required to assess the alternative proposal to see if it satisfies the objectives and goals of the SGMA. If it does not, the local agency is required to form a GSA and develop a GSP. The SGMA required GSAs to be formed by June 30, 2017.

As part of its implementation, DWR has developed a Strategic Plan to document its Sustainable Groundwater Management Program, which expands on its responsibilities in SGMA. The Strategic Plan describes the state's groundwater conditions, identifies legislation, policies, and success factors, describes the goals and objectives of DWR actions, and presents the plan for DWR communication and outreach with stakeholders.

Reception

Support

Support for the act stemmed from the goal of avoiding negative impacts of lowering the water table and subsidence throughout California with implementing specific, measurable objectives. California has had a long history of complex water rights dealing with the ownership and management of surface water. Groundwater has stayed under the regulation radar, which led to the overdraft of vital basins and the subsidence of land taking place throughout the Central Valley. The SGMA gives responsibility to both state authority and local oversight to bring groundwater basins in California to sustainable yields within a given time period.

Criticism

One of the main arguments in opposition of AB 1739 and SB 1168 was from the California Farm Bureau Federation, which was concerned that the bills were rushed and did not allow enough time to address many of the complex issues of groundwater. In addition, the Farm Bureau explained that there would be "huge long-term economic impacts" on farms as well as state and local economies, with a "very real potential to devalue land", thereby affecting the viability of farms and business as well as jobs. Opponents from the CFBF included counties in the Central Valley and agricultural businesses.

Sustainable Groundwater Planning Funds

The approval of Proposition 1, the Water Quality, Supply, and Infrastructure Improvement Act, guaranteed $900 million in funding for the development of a Groundwater Sustainability Program. The State Water Resources Control Board administers $800 million, and the DWR will administer the remaining $100 million as Sustainable Groundwater Planning Grant Funds for developing programs that support the SGMA. The DWR has released the first draft of the Proposal Solicitation Package for GSPs. This initial PSP has made $86.3 million available for the, "planning, development, or preparation of GSPs" and a minimum of $10 million from the initial PSP has been earmarked for Severely Disadvantaged Communities. Eligibility for grant approval requires that the GSPs address high- or medium-priority basins. The SWRCB has already released its initial round of funding for certain preventive and restorative groundwater initiatives which can be seen below.
