Arizona Gov. Jan Brewer signed SB 1307 Tuesday night in an attempt to counter a 2012 bill and prevent the Occupational Safety and Health Administration from asserting its federal oversight role over all industries in Arizona — including residential and commercial construction — but only time will tell whether it will be enough. Mark Minter, executive director of the Arizona Builders Alliance says SB 1307 is a “conditional repeal” action of SB 1441, passed in 2012, that will only go into effect if OSHA follows through on a “show cause” letter delivered to the Industrial Commission of Arizona in March.
