The partial stay of 29 CFR 1910.1001 and 1926.58 is extended until 8/31/91. OSHA is extending the partial administrative stay of the revised final standards for occupational exposure to asbestos, tremolite, anthophyllite and actinolite for general industry and construction, insofar as they apply to occupational exposure to non- asbestiform tremolite, anthophyllite and actinolite. The current partial stay, originally set to expire on 4/21/87 and extended until 11/ 30/90, is being further extended until 8/31/91 to allow OSHA to complete supplemental rulemaking limited to the issue of whether non- asbestiform tremolite, anthophyllite and actinolite should continue to be regulated in the same standard as asbestos, or should be treated in some other way. OSHA also is making minor conforming amendments to notes to the affected standards. CONTACT: James Foster (202)523-8151.
