OSHA is hereby extending the partial administrative stay of the
revised final standards for occupational exposure to asbestos,
tremolite, anthophyllite and actinolite for general industry [1910.
1001] and construction [1926.58], insofar as they apply to
occupational exposure to non-asbestiform tremolite, anthophyllite
and actinolite. The current partial stay, originally set to expire
on April 21, 1987 and extended until July 21, 1988, is being further
extended until July 21, 1989 to allow OSHA to conduct 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 standands.
