VII. Summary and Explanation of the Amendments

1. Definitions

Asbestos

In the 1986 revised asbestos standards (29 CFR sections 1910.1001 and 1926.58) OSHA amended its definition of asbestos in recognition of the fact that different mineral forms exist. "Asbestos was defined to include only the six asbestiform minerals chrysotile, crocidolite, amosite, tremolite asbestos, anthophyllite asbestos, and actinolite asbestos. However in these 1986 revised standards OSHA also added a definition for tremolite, anthophyllite and actinolite. Tremolite, anthophyllite or actinolite without a modifying term such as asbestos or asbestiform referred to only the non-asbestiform forms of these minerals. This definition was added to make clear that all mineral forms would continue to come under the scope of the revised standards.

In this final rule OSHA retains its definition of asbestos as stated in the 1986 revised standards. However the Agency is removing the non-asbestiform minerals from the scope of the revised standards for asbestos and from all paragraphs, and appendices which reference "non-asbestiform tremolite, anthophyllite and actinolite". This removal is based on the determination, made by the Agency, that the health effects data is insufficient to conclude that the non-asbestiform forms of tremolite, anthophyllite and actinolite present the same magnitude or type of effect as their asbestiform analogues.
