The summary materials are available for public review at DEQ’s State Office (1410 North Hilton Street, Boise, Idaho 83706) and on DEQ’s Public Comment Opportunities page. Written comments will be accepted through January 1, 2026, until 5 p.m. Mountain Time. Submit comments electronically using the form below or by mail or email to:
