CFR 117 - Air Contaminants
On January 19, 1989 Federal OSHA published its final rule on Air Contaminants (54 FR 2332-2983) which amended 29 CFR 1910.1000 by lowering permissible exposure limits (PELs) for 212 toxic substances and setting new PELs for 164 previously unregulated toxic substances. The final rule left unchanged the PELs for 51 of 428 substances considered for change and raised one exposure limit.
On June 30, 1993, Federal OSHA announced the revocation of the "Final Rule Limits" column of Table Z-1-A of 29 CFR 1910.1000 (58 FR 35338-35351). In order to effect this change, Table Z-1-A has been removed from 29 CFR 1910.1000 and replaced by Table Z-1 which contains the permissible exposure limits formerly published in the "Transitional Limits" columns of Table Z-1-A.
