Occupational Exposure to Respirable Crystalline Silica; 
Correction

AGENCY: Occupational Safety and Health Administration, Department of 
Labor.

ACTION: Final rule; correcting amendment.

-----------------------------------------------------------------------

SUMMARY: OSHA published a final rule on occupational exposure to 
respirable crystalline silica on March 25, 2016 which became effective 
on June 23, 2016. This document corrects typographical errors in the 
final rule by revising these sections.

DATES: Effective September 1, 2016.

FOR FURTHER INFORMATION CONTACT: Annette Iannucci, Directorate of 
Standards and Guidance, Room N-3718, OSHA, U.S. Department of Labor, 
200 Constitution Avenue NW., Washington, DC 20210; telephone (202) 693-
1950; email [email protected].

SUPPLEMENTARY INFORMATION: On March 25, 2016, OSHA published a final 
rule entitled Occupational Exposure to Respirable Crystalline Silica 
(81 FR 16285-16890). The final rule retained the preceding permissible 
exposure limits (PELs) for respirable crystalline silica in general 
industry (29 CFR 1910.1000, Table Z-3), shipyards (29 CFR 1915.1000, 
Table Z), and construction (29 CFR 1926.55, appendix A), and added 
footnotes to make clear that these PELs apply to any sectors or 
operations where the new PEL of 50 [mu]g/m\3\ is not in effect. The 
preceding PELs apply to operations that are not covered by the new 
standards, such as the processing of sorptive clays. The preceding PELs 
are also applicable during the time between publication of the silica 
rule and the dates established for compliance with the rule, as well as 
in the event of regulatory delay, a stay, or partial or full 
invalidation by the Court.
    This document corrects typographical errors in the formulas for the 
preceding PELs, so that they will appear as they did prior to 
publication of the final rule.
