DEQ seeks comment on draft reuse permit renewal for Mack’s Inn Municipal Wastewater Treatment Facility

Accepting comments from May 2, 2025, through June 2, 2025.

The Idaho Department of Environmental Quality (DEQ) is seeking comment on a draft reuse permit renewal for Fremont County’s Mack’s Inn Municipal Wastewater Treatment Facility.

Fremont County operates a municipal wastewater treatment plant and reuse facility in the Caribou-Targhee National Forest. The facility produces recycled water, which is used to irrigate native vegetation and make snow. The permit renewal would allow the county to continue the beneficial use of municipal recycled water.

The draft reuse permit establishes monitoring requirements, limits on nutrient and hydraulic loading, and conditions established by DEQ to protect public health and the environment. As part of the permitting process, the facility was also required to show that its operation would not cause public health or environmental concerns.

The permit materials are available for public review at DEQ’s Idaho Falls Regional Office (900 North Skyline Drive Suite B, Idaho Falls, Idaho 83406) and on DEQ’s Public Comment Opportunities page. Written comments will be accepted through June 2, 2025, until 5 p.m. Mountain Time. Submit comments electronically using the form below or by mail or email to:
