What's New

The 2025 IDEM Annual Report [PDF] is now available. The report highlights significant environmental progress made throughout Indiana, outlining achievements in air quality, land protection, water resources, and key performance indicators that reflect the agency’s commitment to safeguarding Hoosiers and the environment. The report also provides an overview of major initiatives, permitting performance, statewide monitoring efforts, and the work of IDEM’s nearly 800 employees who serve communities across all 92 counties.

IDEM advises residents affected by the recent storms and tornadoes to exercise caution when managing debris. Debris can pose a risk to health and safety if not handled properly. IDEM has fact sheets to help Hoosiers safely dispose of tornado or storm debris and other household items, such as cleaning supplies, lawn chemicals and other hazardous substances.

You should always follow the directions from local authorities and your local solid waste management district (SWMD). A list of permitted solid waste facilities is provided here.

The Nonpoint Source Program is now accepting proposals for FY2027 Clean Water Act Section 319 grants. Eligible applicants include local governments, nonprofit organizations, universities, and other groups committed to restoring and protecting Indiana’s waterways. Projects may focus on watershed planning, best management practice (BMP) implementation, education and outreach, or other innovative approaches to reducing nonpoint source pollution. Learn more and apply: IDEM: Nonpoint Source: Clean Water Act Section 319(h) Grants.

Senate Enrolled Act 459 mandates cybersecurity measures for certain water and wastewater facilities.  Remember to conduct your first vulnerability assessment and submit a certification by December 31, 2026. See the Cybersecurity for Water/Wastewater Facilities page for more details.

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."
