Federal Occupation Safety and Health Standards - Amendments to OSHA's Air Contaminant Standard

On January 19, 1989 (54 FR 2332), OSHA amended its Air Contaminant Standard, 1910.1000. New PELs were established for many existing and previously unregulated substances. The U.S. Court of Appeals, Eleventh Circuit, issued a decision vacating the "Final Rules" of the Air Contaminants Standard (29 CFR 1910.1000) on July 7, 1992. The Court's decision struck down the entire standard. Effective March 22, 1993, OSHA is enforcing only the following PELs in 29 CFR 1910.1000:

Table Z-1-A: Those specified in the "Transitional Limits" column only

Table Z-2 and Table Z-3: All limits.

PELs specified in 29 CFR 1910.1001 through the end of Subpart Z of Part 1910 are unaffected by the Court's decision.
