BLM California Air Resources Program

The Bureau of Land Management (BLM) California stewards air resources across 15 million acres of public lands and 47 million acres of Federal mineral estate in California and an additional 1.6 million acres of public land in northwestern Nevada. The Federal Land Policy Management Act (FLPMA) guides the BLM in managing public lands in a way that protects air and atmospheric values from undue degradation. Air quality in California is overseen by the U.S.EPA and managed by State and local agencies that have been delegated authority under the Clean Air Act (CAA), including the California Air Resources Board and California’s 35 county or regional air districts. The BLM coordinates with these agencies to access monitoring data, develop emission estimation methodologies, and to meet its CAA responsibility to determine that activities it approves on BLM public lands conform to the implementation plans that the CAA agencies have established.
