The U.S. Environmental Protection Agency (EPA) is offering consultation with federally recognized Tribes regarding the Agency’s proposed Federal plan requirements for existing Other Solid Waste Incineration (OSWI) units that commenced construction on or before August 31, 2020, and have not been modified or reconstructed after August 29, 2025.
The proposed Federal plan would implement emission guidelines for OSWI units located in states or Tribal lands that do not have an approved State or Tribal plan in place. The rule would remain in effect until individual states or Tribes have approved plans of their own.
EPA anticipates the Tribal consultation period will remain open through August 17, 2026, and invites Tribal leaders and designated representatives to provide input, including information related to treaty or similar rights, Indigenous Knowledge, and sacred sites.
Request Government-to-Government Consultation by: August 3, 2026
Public Comments: Tribes may submit comments through the open Federal Register comment period under Docket ID No. EPA-HQ-OAR-2025-3028.
