Naturally occurring asbestos (NOA) found in rock, soil and dust is regulated by a multitude of organizations including CARB, DTSC, CalOSHA/Fed OSHA, EPA NESHAPS and other various local and state governmental entities.

Exposure to hazardous asbestos fibers from NOA typically occurs during any activities which disturb rock and soil including: drilling, grading, and other heavy construction and mining activities, as well incidental exposures from driving on NOA covered roadways.
