RULE 6-110 - AIRBORNE TOXIC CONTROL MEASURE FOR ASBESTOS-CONTAINING SERPENTINE ROCK

(Adopted April 6, 1993)

PURPOSE:

On March 27, 1986, pursuant to Section 39662 of the Health and Safety Code, the Air Resources Board identified asbestos (in the following forms: chrysotile, crocidolite, amosite, tremolite, actinolite, and anthophyllite) as a toxic air contaminant pursuant to Health and Safety Code Sections 39650 et seq. In so identifying asbestos, the Air Resources Board determined that available scientific evidence is not sufficient to support identification of a threshold exposure level below which no significant adverse health effects are anticipated. This airborne toxic control measure is expected to reduce asbestos emissions from future use of asbestos-containing serpentine material in surfacing applications to the lowest level achievable through a prohibition on the sale and use of asbestos-containing serpentine material.

This regulation is adopted in accordance with the requirements of Health and Safety Code Section 39666(d) and of California Code of Regulations Section 93104.
