A diverse set of groups is standing against legislation they say would weaken Indiana's ability to protect the health and safety of Hoosiers. House Bill 1143 would require Indiana's environmental rules and standards to be no stronger than federal ones. Former legal counsel to the Indiana Department of Environmental Management Rosemary Spaulding is among those concerned. "It just totally hamstrings our environmental rules board," Spaulding said, "in terms of giving them the flexibility they need to do appropriate rules for what's in the best interest of Indiana citizens." Sixteen Indiana-based groups on Wednesday announced opposition to the bill, including the Indiana State Medical Association, The League of Women Voters of Indiana, Indiana Wildlife Federation, and Hoosier Interfaith Power and Light. It was approved by the House and could be heard by a Senate committee as early as Monday The bill was authored by Republican Warsaw Representative David Wolkins, who says federal regulations are strong and legislation is needed to prevent negative economic repercussions if future Indiana leaders call for tests or standards that state can't afford.
