​​​Welcome to the California Department of Conservation

The Department of Conservation provides services and information that promote environmental health, economic vitality, informed land-use decisions and sound management of our state's natural resources.

The Department of Conservation is underway in its Renewal Plan to strengthen and improve the state’s oversight of oil and gas production in California.

​​​​State to Permanently Seal Two Deserted L.A. Oil Wells

The Department of Conservation/Division of Oil, Gas, and Geothermal Resources, in cooperation with the City of Los Angeles, will permanently seal two oil wells that were deserted by irresponsible operators and have seeped small amounts of gas in a residential neighborhood. The wells pose no imminent danger but are a nuisance and will continue to deteriorate without intervention.

​​​​Testing Results of Aliso Canyon Wells Available

The Department of Conservation’s Division of Oil, Gas, and Geothermal Resources has ordered that all 114 injection wells be thoroughly tested for safety and competence before injection resumes into the Aliso Canyon natural gas storage field. The Division developed a protocol of six tests in consultation with the Lawrence Livermore and Berkeley National Laboratories. Test results are submitted by Southern California Gas, reviewed by Division staff, and then posted on this page, which will be updated frequently. Wells must pass all tests within one year or be permanently sealed (plugged and abandoned).

View additional Aliso Canyon information – including biweekly reports Southern California Gas must file on its progress toward completing the safety review.

​​​​New Program Keeps Land in Agricultural Use Forever

Two ranches in Napa County are the first properties permanently shielded from development by the new Sustainable Agricultural Lands Conservation Program, administered by the Division of Land Resource Protection.

​​​​Governor Brown Signs Major Reforms to Mining Law

With the enactment of two bills on April 18, California strengthened the Surface Mining and Reclamation Act to better ensure that mine operators restore lands to a natural or usable condition after mining production ends. Governor Edmund G. Brown Jr. in 2014 directed the department to work with stakeholders to develop substantive and procedural changes to the state’s mining law. The newly-signed bills – SB 209 by Senator Fran Pavley (D-Agoura Hills) and AB 1142 by Assemblymember Adam Gray (D-Merced) – are the result of that stakeholder process.

​​​​State Accepting Comments on Aquifer Exemption Application

State regulators are accepting public comments on a proposal to expand the existing aquifer exemption in the Round Mountain oil field in Kern County. The comment period runs through June 25 and included a public meeting in Bakersfield on June 14. Read the news release. Get more information on the aquifer exemption process.

​​​​Oil Producer Fined $75,000

State regulators have issued a $75,000 civil penalty order to The Termo Company for illegally venting natural gas in the Aliso Canyon field.  The California Division of Oil, Gas, and Geothermal Resources levied $25,000 penalties for each of three violations, noting that not only did the gas venting appear to be intentional, but also that the Long Beach-based operator tried to hide it. Read the news release.

​​​​Aliso Canyon​ Natural Gas Update

Officials Confirm Gas Leak is Sealed

State regulators including the Department of Conservation’s Division of Oil, Gas and Geothermal Resources (Division) on February 18, 2016 provided public notice that the leaking well (SS25) at the Aliso Canyon Gas Storage Facility in Los Angeles County has been successfully sealed. More information about the Aliso Canyon facility.

​​Natural Gas Storage Rulemaking

DOC’s Division of Oil, Gas, and Geothermal Resources is preparing to undertake rulemaking to make significant revisions to the regulations governing the Division’s Gas Storage Program.  This rulemaking effort will build upon the requirements adopted by emergency rulemaking to update regulations and address concerns identified by the Division and other key stakeholders.  The document outlines the Division’s immediate regulatory goals. Public input was accepted until March 18.
