PELS

WAC 296-841-100 to 296-841-300

Washington has adopted the federal "Z tables" of air contaminants (Z tables at 29 CFR 1910.1000) with stricter exposure limits for many substances, and added several hazardous substances. The state's air contaminants standard for agriculture contains a shorter table of chemicals.

Federal OSHA had revised its Z tables of hazardous substances and PELs in the 1980s to include the substances adopted by Washington's standards, but in 1989 a federal circuit court struck down the OSHA revisions. Several states, including California and Oregon, retained the revised OSHA Z tables, which are stricter than existing federal standards.
