The California Department of Conservation is a department within the government of California, belonging to the California Natural Resources Agency. With a team of scientists, engineers, environmental experts, and other specialists, the Department of Conservation administers a variety of programs vital to California’s public safety, environment and economy. The department’s mission is to manage California’s working lands. It regulates oil, natural gas and geothermal wells; studies and maps earthquakes and other geologic phenomena; maps and classifies areas containing mineral deposits; ensures reclamation of land used for mining; and administers agricultural and open-space land conservation programs. A division within the department dedicated to encouraging beverage container recycling has been moved into the newly created Department of Resources Recovery and Recycling (CalRecycle). Despite the similar name, the Department of Conservation should not be confused with the California Conservation Corps, another department within the Natural Resources Agency, which provides work experience for young adults. The Department of Conservation often collaborates with its federal equivalents, such as the U.S. Geological Survey.

The department's director is Marc Nechodom.

The Department of Conservation is divided into five divisions to oversee its various responsibilities.

California Geological Survey (CGS)

The California Geological Survey provides scientific analysis of the state's geology, seismic hazards, and mineral resources. Historically, CGS began as a short-lived California Geological Survey (1860-1874). In 1880, the California Legislature created the State Mining Bureau, which focused solely on mining and mineral resources and reported directly to the Governor. The Bureau gradually added authority to regulate oil and gas development, as well as forestry (timber to support mining was a major issue of the day). In 1927, as California Government grew, the Bureau became the Division of Mines within the State's Department of Natural Resources. About the same time, responsibilities for forests were given to a new Division of Forestry, and oil and gas to a new Division of Oil and Gas, both in the Department of Natural resources.

Although mining remained the focus of the Division of Mines, emphasis began to grow in basic geologic products through the 1940s and 1950s. In 1961, the name was changed to Division of Mines and Geology (DMG), with a greater emphasis on environmental geology in urban areas. Following the 1971 San Fernando Earthquake, DMG was authorized to delineate regulatory zones along earthquake faults and install instruments to record earthquake strong motion. In 1976, it was authorized to help assure reclamation of mined lands, and in 1990 to delineate regulatory zones for liquefaction, earthquake-triggered landslides, and tsunamis. In January 1991, reclamation-related responsibilities were moved to a new Office of Mine Reclamation. In 2002, the Division unofficially began using the name California Geological Survey, a change that was formally authorized in 2006 by the California Legislature.[3]

Division of Land Resource Protection

Promoting conservation, the Division of Resource Protection oversees studies regarding urban sprawl, the use of farmland, and regularly monitors and maps the loss of farmland to urban growth.

Office of Mine Reclamation

The Surface Mining and Reclamation Act of 1975 (SMARA) gave the Department of Conservation responsibilities related to reclamation of mined lands. Initially these responsibilities were allocated to the Division of Mines and Geology, working in concert with the State Mining and Geology Board and local governments. In 1991, those responsibilities were transferred to the Office of Mine Reclamation. OMR is involved in every mining operation within the state, studying the ability of mining operations to restore land to its previously unaltered state following the cessation of mine operations.

Division of Oil, Gas, and Geothermal Resources (DOGGR)

The Division of Oil, Gas, and Geothermal Resources oversees the drilling, operation, maintenance, and the plugging of abandoned oil, natural gas and geothermal wells. DOGGR is also one of the main state sources for information about the state's oil, gas and geothermal industry, with more than 170,000 well records, production and injection statistics, well logs and field maps.

DOGGR also maintains a database of active wells, expired wells, surveyed lands and leases on California land, coastal waters (0–3 miles) and federal Outer Continental Shelf (OCS). When a well is no longer needed, either because the oil or gas reservoir becomes depleted, or because no oil or gas was found (called a dry-hole), the well is plugged and abandoned. A well is plugged by placing cement in the well-bore or casing at certain intervals as specified in California laws or regulations. The purpose of the cement is to seal the wellbore or casing and prevent fluid from migrating between underground rock layers. Cement plugs are required to be placed across the oil or gas reservoir (zone plug), across the base-of-fresh-water (BFW plug), and at the surface (surface plug). Other cement plugs may be required at the bottom of a string of open casing (shoe plug), on top of tools that may become stuck down hole (junk plug), on top of cut casing (stub plug), or anywhere else where a cement plug may be needed. Also, the hole is filled with drilling mud to help prevent the migration of fluids.

In 2014 DOGGR officials admitted that for several years they had "inadvertently" permitted companies to inject potentially hazardous wastewater from fracking and other oil production operations "into hundreds of disposal wells in protected aquifers" in violation of federal law. The oversight was attributed to "haphazard record-keeping and antiquated data collection."[4]

State Mining and Geology Board

The State Mining and Geology Board is granted certain autonomous responsibilities and obligations under several statutes within the Department of Conservation. The board's general authority requires its nine board members to "represent the general public interest." The board serves as a regulatory, policy and appeals body representing the state's interest in geology, geologic and seismologic hazards, conservation of mineral resources, and reclamation following surface mining activities.
