Rules and Regulatory Notices

IDEM regularly notifies the public about rulemaking activities via official public notices in the Indiana Register. Relevant information, public hearing dates, and agency points of contact are included in the notices.

To receive electronic updates on rulemaking activities, check the boxes next to the "Board and Rules" listings in the "Legal Counsel". Be sure to check the boxes next to the board packet listings to receive board packets.

A nonrule policy document (NPD) is intended to clarify for the public IDEM's interpretation of an environmental statute or rule. IDEM Nonrule Policies are not intended by the agency to have the effect of law, however, per Indiana Code 13-14-1-11.5, they are made available for public comment on the agency internet website for at least 45 days. After the comment period ends, the appropriate state environmental board(s) are briefed, and 30 days later the NPD(s) become effective and are sent for publication in the Indiana Register.

Citizen Involvement

The Citizens’ Guide to IDEM describes the agency’s permitting and environmental cleanup programs. The guide details how citizens can participate when IDEM makes decisions about issuing permits, conducting cleanup actions, preparing environmental reports and plans, and writing environmental rules.
