Existing law, the Sustainable Groundwater Management Act, requires all groundwater basins designated as high- or medium-priority basins by the Department of Water Resources that are designated as basins subject to critical conditions of overdraft to be managed under a groundwater sustainability plan or coordinated groundwater sustainability plans by January 31, 2020, and requires all other groundwater basins designated as high- or medium-priority basins to be managed under a groundwater sustainability plan or coordinated groundwater sustainability plans by January 31, 2022, except as specified. The act authorizes the State Water Resources Control Board to designate a basin as a probationary basin if the board makes a certain determination and authorizes the board to adopt an interim plan for a probationary basin, as specified. The act authorizes the board to order a person that extracts or
uses water from a basin that is subject to a certain investigation or proceeding by the board to prepare and submit to the board any technical or monitoring program reports related to that person’s or entity’s extraction or use of water as the board may specify.
This bill would make nonsubstantive changes in a definition used in the act.
As used in this chapter, the following terms have the following meanings:
(a)“Condition of long-term overdraft” means the condition of a groundwater basin where the average annual amount of water extracted for a long-term period, generally 10 years or more, exceeds the long-term average annual supply of water to the basin, plus any temporary surplus. Overdraft during a period of drought is not sufficient to establish a condition of long-term overdraft if extractions and recharge are managed as necessary to ensure that reductions in groundwater levels or storage during a period of drought are offset by increases in groundwater levels or storage during other periods.
(b)“Person” means any person, firm, association, organization, partnership, business, trust, corporation, limited liability company, or public agency, including any
city, county, city and county, district, joint powers authority, state, or any agency or department of those entities. “Person” includes, to the extent authorized by federal or tribal law and subject to the limitations described in subdivisions (c) and (d) of Section 10720.3, the United States, a department, agency, or instrumentality of the federal government, an Indian tribe, an authorized Indian tribal organization, or an interstate body.
(c)“Probationary basin” means a basin for which the board has issued a determination under Section 10735.2.
(d)“Significant depletions of interconnected surface waters” means reductions in flow or levels of
surface water that is hydrologically connected to the basin such that the reduced surface water flow or levels have a significant and unreasonable adverse impact on beneficial uses of the surface water.
