IDEM Seeks Input on Evaluation of Existing Regulations
Between January and April 2025, 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."
IDEM is soliciting public input related to these executive orders (see Public Notice), with all feedback to be submitted by June 30, 2025, to efficiency@idem.IN.gov.
2026 Ambient Air Monitoring Network Plan
Federal regulations (40 CFR 58.10) require IDEM to review Indiana’s ambient air monitoring network annually to assess the current network and determine if any changes are necessary to meet the monitoring goals and carry out monitoring projects across the state. IDEM evaluates many factors when reviewing the network plan, including current National Ambient Air Quality Standards (NAAQS), data trends, population changes, new monitoring projects, site redundancy, siting problems, site access concerns, and other identified monitoring issues.
IDEM is required to develop and submit an annual monitoring network plan to U.S. EPA that details the current air quality surveillance system and proposed changes for the coming year. The public can review the proposed 2026 plan and submit comments by June 18. Instructions on how to submit comments are located in Appendix A (Page 79) of the proposed plan.
Indiana State Materials Management Plan
The Indiana State Materials Management Plan (MMP) aims to provide a statewide roadmap to improve how pre- and post-consumer materials are managed and reduce waste across the state. Input solicited during the planning process will be instrumental in developing a comprehensive new MMP that promotes a circular economy for materials while supporting statewide efforts to advance pre- and post-consumer materials management.
