The Idaho Department of Environmental Quality (DEQ) is seeking comment on a draft reuse permit renewal (M-047-04) for the city of Ashton’s wastewater treatment facility.
The city of Ashton owns and operates a public municipal Class I wastewater collections system and treatment plant and Class C reuse facility that applies recycled water to agricultural land. The facility is located 1/2 a mile north of Ashton and west of the Highway 20 and Tesoro Station intersection. The treatment process produces Class C recycled water and uses it to irrigate 77 acres of alfalfa or grass hay during the growing season.
The permit would authorize reuse operations until 2036 and establish monitoring requirements, limits on nutrient and hydraulic loading, and conditions established by DEQ to protect public health and the environment.
The permit materials are available for public review at DEQ’s State Office (1410 North Hilton Street, Boise, Idaho 83706), Idaho Falls Regional Office (900 N. Skyline Drive, Suite B Idaho Falls, ID 83402), and on DEQ’s Public Comment Opportunities page. Written comments will be accepted through January 5, 2026, until 5 p.m. MDT. Submit comments electronically on DEQ’s website or by mail or email to:
