Bill	Surface mining: Metropolitan Water District of Southern California.	(1) The Surface Mining and Reclamation Act of 1975 prohibits a person, with exceptions, from conducting surface mining operations unless, among other things, a permit is obtained from, a specified reclamation plan is submitted to and approved by, and financial assurances for reclamation have been approved by, the lead agency for the operation of the surface mining operation. Existing law authorizes the Metropolitan Water District of Southern California (MWD) to prepare a master reclamation plan, as provided, that identifies each individual surface mining operation in specified counties and satisfies all reclamation plan requirements for each individual surface mining site. Existing law requires the State Mining and Geology Board to act as the lead agency for surface mining operations conducted by the MWD and authorizes the board to conduct an inspection of an individual surface mining operation once every 2 calendar years during a period when that individual surface mining operation is idle or the site has no mineral production. Existing law requires the MWD to be the lead agency for any environmental review of the master reclamation plan. Existing law repeals the provisions authorizing the preparation and approval of the master reclamation plan for the MWD on January 1, 2026.	us/states/ca	California Legislature	20252026	AB 580	California AB 580 (20252026)	bill	MetropolitanWaterDistrictofSouthernCalifornia Surfacemining	enacted	Wallis	6	22	7	2025-02-12	2025-10-03	openstates	ocd-bill/36cbb0bc-66ee-4dff-bc6e-3aaf2b98d3a6	http://leginfo.legislature.ca.gov/faces/billNavClient.xhtml?bill_id=202520260AB580	3c41a4c4590286f683bb175308273db080fd30ef4a9f1f47e24c297bd662defb	2026-07-01	https://data.openstates.org/daily/2026-07-01/public.pgdump	2026-07-06	reported	legislation bill us-ca
