Existing law, the Sustainable Groundwater Management Act, requires all groundwater basins designated as high- or medium-priority basins by the Department of Water Resources to be managed under a groundwater sustainability plan or coordinated groundwater sustainability plans, except as specified. Existing law authorizes any local agency or combination of local agencies overlying a groundwater basin to decide to become a groundwater sustainability agency for that basin and imposes specified duties upon that agency or combination of agencies, as provided. Existing law authorizes a groundwater sustainability agency to request of the county, and requires a county to consider, that the county forward permit requests for the construction of new groundwater wells, the enlarging of existing groundwater wells, and the reactivation of abandoned groundwater wells to the agency before permit approval.
This bill would instead require a county to forward permit requests for the construction of new groundwater wells, the enlarging of existing groundwater wells, and the reactivation of abandoned groundwater wells to the groundwater sustainability agency before permit approval.
Existing law requires the State Water Resources Control Board to adopt a model water well, cathodic protection well, and monitoring well drilling and abandonment ordinance implementing certain standards for water well construction, maintenance, and abandonment and requires each county, city, or water agency, where appropriate, not later than January 15, 1990, to adopt a water well, cathodic protection well, and monitoring well drilling and abandonment ordinance that meets or exceeds certain standards. Under existing law, if a county, city, or water agency, where appropriate, fails to adopt an ordinance establishing water well, cathodic protection well, and monitoring well drilling and abandonment standards, the model ordinance adopted by the state board is required to take effect on February 15, 1990, and is required to be enforced by the county or city and have the same force and effect as if adopted as a county or city ordinance.
This bill would prohibit a county, city, or any other water well permitting agency from approving a permit for a new groundwater well or for an alteration to an existing well in a basin subject to the act and classified as a critically overdrafted basin unless specified conditions are met. Among these conditions, the bill would require a county, city, or any other water well permitting agency to obtain a written verification from the groundwater sustainability agency that manages the basin or area of the basin where the well is proposed to be located determining that, among other things, the extraction by the proposed well is consistent with any sustainable groundwater management program established in any applicable groundwater sustainability plan adopted by that groundwater sustainability agency or an alternate plan approved or under review by the Department of Water Resources.
The bill would also require, as a condition of approving a permit for a new groundwater well or for an alteration to an existing well in an above-described basin, a county, city, or any other water well permitting agency to, among other things, post the well permit application on its internet website for at least 30 days before approving the permit. By imposing additional requirements on a county, city, or any other water well permitting agency, the bill would impose a state-mandated local program.
This bill would provide various exemptions from the above-described provisions, including exempting a permit for any well that provides less than 2 acre-feet of water annually for domestic use or any well used by a public water supply system or state small water system.
The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement.
This bill would provide that no reimbursement is required by this act for a specified reason.
