IDEM Report on Evaluation of Existing Regulations
Governor Mike Braun issued a series of executive orders to streamline Indiana's environmental regulation approach, including Executive Order 25-38. EO 25-38 directs agencies responsible for environmental regulations to "identify state environmental regulations and policies that are unduly burdensome, significantly raise the cost of living for Hoosiers, are not supported by current law and the best available science, or do not benefit Indiana's environment."
EO 25-38 established that relevant agencies should "report opportunities to revisit or rescind such state environmental regulations to the Governor's Office no later than July 1, 2025."
