It may not be the sexiest measure at the Capitol but it  will go down in history as the first bill Gov. Mark Dayton enacted.

Dayton signed SF 139 into law Thursday.

According to the governor's office: "Under current law, a building inspector must prove that a contractor received their EPA certificate in lead specialization when remodeling pre-1978 houses, by confirming their certification online. Under SF139, contractors who receive their certification now have until August 1st to post their name on the verified list, viewable on the Department of Labor and Industry’s website."
