​​​​​​​​​​​Welcome to the State Mining & Geology Board (SMGB)

The SMGB represents the State's interest in the development, utilization and conservation of mineral resources; reclamation of mined lands; development of geologic and seismic hazard information; and to provide a forum for public participation​.

 ​​​The SMGB held a series of pre-rulemaking workshops ​to discuss Financial Assurance Cost Estimate Form revisions and general SMARA reform regulatory actions. Further information can be found here.


​The SMGB in cooperation with the Department of Cons​erv​a​​tion is undertaking a compre​​​hensive​ rulemaking effort to enact significant revisions to the Surface Mining and Reclamation Act (SMARA) following the passage of two bills.  SB 209 (Pavley) and AB 1142 (Gray) were signed into law on April 18, 2016 and require significant changes.  For additional information on the regulatory packages, please see the ongoing rulemaking page.


On April 18, 2016, Governor Brown signed SB 209 (Pavley) and AB 1142 (Gray) into law and thereby enacted significant changes to the Surface Mining and Reclamation Act of 1975 (SMARA).  These reforms affect how the State Mining and Geology Board (SMGB) and the Department of Conservation (DOC), local  lead agencies, and surface mine operators oversee, implement and comply with SMARA.  For more information please see the Department’s press release regarding this recent SMARA reform effort, available he​re​.

​The SMGB's regulations pertaining to the designation of mineral lands in the North San Francisco Bay
​​P-C Region were approved by OAL on February 9, 2016, and became effective April 1, 2016.

​​​Meeting Information​​

The December 8 meeting has been canceled.  The next meeting is scheduled for January 12 in Sacramento. ​​

SMGB Authorities​

The SMGB is composed of nine members appointed by the Governor, and confirmed by the Senate, for four-year terms. The SMGB serves as a regulatory, policy, and appeals body representing the State's interests in geology, geologic and seismologic hazards, conservation of mineral resources and reclamation of lands following surface mining activities.

The SMGB operates within the Department of Conservation, and is granted certain autonomous responsibilities and obligations under several statutes including the Alquist-Priolo Earthquake Fault Zoning Act, the Seismic Hazards Mapping Act, and the Surface Mining and Reclamation Act. The SMGB's general authority is granted under Public Resources Code (PRC) Sections 660-678. Specifically, PRC Section 662(b) requires all SMGB members to "represent the general public interest".
