Minnesota has adopted the 1989-1992 version of the federal "Z tables" of air contaminants that contain stricter exposure limits for many substances than the current federal PEL rule (Z tables at 29 CFR 1910.1000)

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. At least eight other states, including California, Oregon, and Michigan, retained the revised OSHA Z tables which are stricter than existing federal standards.
