The Idaho Department of Environmental Quality (DEQ) is seeking comment on a draft 401 water quality certification for the Camas Creek bridge replacement project.
The purpose of this project is to replace two deteriorated existing bridges (Bridge 23795 and Bridge 23800) with a single, modern structure designed to accommodate two-way traffic and safely support heavy vehicle loads, including larger trucks and agricultural equipment. The proposed bridge will be engineered to withstand high-flow conditions in Camas Creek and reduce the potential for roadway overtopping. The existing side channel currently conveyed beneath Bridge 23795 will be realigned and shifted to the southeast. The proposed project would result in approximately 830 linear feet of stream impacts and 3,514 square feet of wetland impacts. The project is a part of the Leading Idaho Local Bridge Program.
Based upon review of the federal joint 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), 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 public review at DEQ’s State Office (1410 N. Hilton St. Boise, Idaho 83706), DEQ’s Twin Falls Regional Office (650 Addison Avenue West, Suite 110 Twin Falls ID 83301), and on DEQ’s website. Written comments will be accepted through March 3, 2026, at 5 p.m. Mountain Time. Submit comments electronically using the form below or by mail or email to:
