Abstract:

Occupational exposure to asbestos, tremolite, anthophyllite and
actinolite for general industry (1910.1001) and construction
(1926.58) which were promulgated on June 17, 1986 and were published
on June 20, 1986 and became effective on July 21, 1986 (51 FR
22612). This document gives notice of a 9-month administrative stay
of the revised standards insofar as they apply to occupational
exposure to non-asbestiform tremolite, anthophyllite and actinolite.
This stay is granted for the purpose of reopening the record,
reviewing new submissions and conducting supplemental rulemaking as
to whether should be regulated in the same standard as asbestos.
This stay applies only to the application of the revised standards
to non-asbestiform tremolite, anthophyllite and actinolite. In all
other respects, the revised standards will take effect as previously
scheduled. During the period of the stay, the provisions of the 1972
standard governing occupational exposure to asbestos will remain in
effect with respect to regulation of non-asbestiform tremolite,
anthophylite and actinolite. The 1972 standard is redesignated as
1910.1101 to distinguish it from the revised standard for general
industry which is designated as 1910.1001. The provisions in the
prior standard which constituted the Emergency Temporary Standard
for Asbestos issued in November 1983 are being deleted. The partial
stay of 1910.1001 and 1926.58 was effective July 21, 1986 and will
expire April 21, 1987. Revisions to the 1972 standard republished as
1910.1101 and all other amendments in this rule are effective
October 17, 1986.
