In this final standard OSHA amends its present standards for regulating occupational exposure to asbestos in general industry and construction standards. OSHA has reviewed available relevant evidence concerning the health effects of nonasbestiform tremolite, anthophyllite and actinolite and has also examined the feasibility of various regulatory options. Based on the entire rulemaking record before it, OSHA has made a determination that substantial evidence is lacking to conclude that nonasbestiform tremolite, anthophyllite and actinolite present the same type or magnitude of health effect as asbestos. Further, substantial evidence does not support a finding that exposed employees would be at a significant risk because nonasbestiform tremolite, anthophyllite or actinolite was not regulated in the asbestos standards to remove nonasbestiform tremolite, anthophyllite and actinolite from their scope. The final shall become effective May 29, 1992. The Administrative Stay expired May 30, 1992. Further information may be obtained by contacting James F.
