Advisory

Planned prescribed burning on Angel Island Wednesday has been canceled.
Air quality is improving following today’s burn, and the Air District continues to monitor smoke across the region. Crews may remain on site tomorrow to extinguish remaining hot spots, but no additional prescribed burning is planned. Wednesday’s Spare the Air Alert is for ozone and is separate from today’s smoke impacts.

Naturally Occurring Asbestos
Learn about the Air District’s Naturally Occurring Asbestos Program and find notification forms, regulatory information, and more.
Asbestos is a naturally occurring mineral often used in building materials and construction. Because asbestos has been proven to cause serious and fatal diseases, it is strictly regulated in its use as a building material and where it occurs naturally.
Naturally Occurring Asbestos Program
To reduce public exposure to naturally occurring asbestos, the Air District regulates all construction and mining activities that produce dust potentially containing naturally occurring asbestos. The Airborne Toxic Control Measure places requirements on the following activities in areas where naturally occurring asbestos is likely to be found:
- Road construction and maintenance.
- Construction and grading.
- Quarrying and surface mining.
