DEQ seeks comment on request to implement federal municipal solid waste landfills requirements 

Accepting comments from September 16, 2025, through October 16, 2025. 

The Idaho Department of Environmental Quality (DEQ) is seeking comment on a request for delegated authority to implement emission guidelines for municipal solid waste landfills. 

The request was submitted to the United States Environmental Protection Agency and seeks authority over the “Federal Plan Requirements for Municipal Solid Waste Landfills That Commenced Construction On or Before July 17, 2014, and Have Not Been Modified or Reconstructed Since July 17, 2014” (40 CFR Part 62, Subpart OO). This would allow the State of Idaho to assume primacy for managing emission control requirements for eligible municipal solid waste landfills within the state. 

The proposed submittal is available for public review on DEQ’s website and at DEQ’s State Office (1410 North Hilton Street, Boise, Idaho). Written comments will be accepted through October 16, 2025, at 5 p.m. MST.  A public hearing is scheduled for October 16, 2025, at 2:00 pm MST at DEQ’s State Office or via Teams. 

Submit comments electronically using the form below or by mail or email to:
