(a) The Hawaii State plan received initial approval on January 4, 1974.

(b) The Hawaii State plan received final approval on May 4, 1984.

(c) On September 21, 2012 OSHA modified the State Plan's approval status from final approval to initial approval, and reinstated concurrent federal enforcement authority pending the necessary corrective action by the State Plan in order to once again meet the criteria for a final approval determination. OSHA and Hawaii entered into an operational status agreement to provide a workable division of enforcement responsibilities.

(d) The plan covers all private-sector employers and employees, with several notable exceptions, as well as State and local government employers and employees, within the State.
