The California Air Resource Board (CARB) promulgated the Airborne Toxic Control Measure (ATCM) for Construction, Grading, Quarrying and Surface Mining Operations. This statewide regulation is triggered prior to the grading or disturbance of soil in certain areas of California. The ATCM applies to any size construction project although there are more stringent mitigation requirements for projects that exceed one acre. The areas most likely to contain naturally occurring asbestos are the eastern parts of Sacramento County, Folsom and Rancho Murieta. This page was created as a resource for contractors doing work in those areas of Sacramento County as well as residents of those areas.
