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

The mission of the State Mining and Geology Board is to provide profession​al expertise and guidance, and to represent ​the State's interest in the development, utilization, and conservation of mineral resources, the reclamation of mined lands, and the development and dissemination of geologic and seismic hazard information to protect the health and welfare of the people of California.

Preliminary Review Maps of proposed revised Alquist-Priolo Earthquake Fault Zones were released on December 15, 2016 to the cities of Arcadia, Los Angeles, Monrovia, Pasadena, San Marino, and South Pasadena, and the County of Los Angeles by the California Geological Survey (CGS).  These maps are released under the authority of the Alquist-Priolo Earthquake Fault Zoning (AP) Act that was passed following the 1971 San Fernando earthquake.  The AP Act is a state law designed to reduce the hazard from surface fault rupture during an earthquake.

Earthquake Fault Zones are regulatory zones that encompass surface traces of active faults that have a potential for future surface fault rupture.  The index map shows the general location of maps delineating the proposed Earthquake Fault Zones within the affected areas.  Click here to view or download the proposed revised maps and their associated Fault Evaluation reports.

​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 and updates​ 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 next regular business meeting is scheduled for April 13 in Sacramento. ​​ The Agenda Notice  will be published on March 29.​

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".
