The Idaho Department of Environmental Quality (DEQ) is seeking comment on a draft water quality certification for the Darby Meadows Ranch project.

The objective of the proposed project is to develop an access driveway, future homesite, and a wetland mitigation feature impacting Darby Creek and associated emergent wetlands.

Based upon review of the federal permit application, readily available water quality related materials, and certification request in accordance with 40 CFR §§ 121.5 (b) and (c) and 121.7 (c), received on, 7/2/2025, DEQ, certifies that if the permittee complies with the terms and conditions imposed by the federal permit and the conditions set forth in this water quality certification, then it is reasonable for DEQ to conclude that the activity will comply with water quality requirements, including applicable requirements of the Clean Water Act §§ 301, 302, 303, 306, and 307, Idaho’s “Water Quality Standards” (IDAPA 58.01.02), and other appropriate water quality requirements of state law.

The draft certification is available for review on DEQ’s website. Written comments will be accepted through August 13, 2025, at 5 p.m. Mountain Time. Submit comments electronically using the form below or by mail or email to:
