The Air Resources Board (ARB) has adopted two Airborne Toxic Control Measures (ATCMs) for naturally-occurring asbestos. The first is the Asbestos ATCM for Surfacing Applications and the second is the Asbestos ATCM for Construction, Grading, Quarrying, and Surface Mining Operations. Also, the U.S. EPA is responsible for enforcing regulations relating to asbestos renovations and demolitions. However, the U.S. EPA can delegate this authority to state and local agencies. The ARB and local air districts have received delegated authority to enforce the federal National Emission Standards for Hazardous Air Pollutants (NESHAPS) regulations for asbestos.
Asbestos ATCM for Surfacing Applications - This ATCM restricts the asbestos content of material used in surfacing applications such as unpaved roads, parking lots, driveways, and walkways.
Asbestos ATCM for Construction, Grading, Quarrying, and Surface Mining Operations - This ATCM requires the implementation of mitigation measures to minimize emissions of asbestos-laden dust.
