Indiana State Agency Takes Over Data Center Water Oversight
What happened
The Indiana Department of Environmental Management began overseeing surface water impacts at data center sites in Indiana on October 12, 2026. This oversight applies to five data center developments that contain wetlands, streams, or ponds. Previously, these sites would have required a federal permit from the Army Corps of Engineers.

Why it matters
The shift occurred after a U.S. Supreme Court decision in 2023 narrowed the scope of the Clean Water Act, removing federal jurisdiction over many surface waters. By taking over, the Indiana Department of Environmental Management allows these data centers to avoid the federal process, which included extensive public input and the possibility of permit denial.
