Minnesota’s top health and environmental officials sent a blistering letter Wednesday to the U.S. Environmental Protection Agency, charging that its controversial plan to impose broad new restrictions on the types of scientific research it uses to craft regulations will cause confusion, mistrust and “threaten the lives of real people” “EPA should withdraw this dangerous proposal,” wrote John Linc Stine, commissioner of the Minnesota Pollution Control Agency and Jan Malcolm, state health commissioner.It is the most forceful public criticism that Minnesota officials have issued since Administrator Scott Pruitt began imposing sweeping reversals of long-held EPA regulatory policies. Stine characterized the letter as “speaking truth” to the agency.
