Welcome to the IDEM rules information web-site. This site has information on all on-going rulemaking projects, an archive of recently completed rules, and information on the two rulemaking boards charged with adopting rules to be implemented and administered by IDEM. Those two boards are the Environmental Rules Board and the Underground Storage Tank Financial Assurance Board. The Environmental Rules Board was created in the 2012 Indiana General Assembly and replaces the Air Pollution Control Board, Water Pollution Control Board, and Solid Waste Management Board. The new Environmental Rules Board will adopt the rules for all three media. Board packets for both boards can be accessed from this site.
