Accepting comments from September 12, 2025, through October 3, 2025.
The Idaho Department of Environmental Quality (DEQ) is seeking public comment opportunity on a 401 water quality certification for Verbena Ranch Subdivision project.
The proposed Verbena Ranch Subdivision in Caldwell, Idaho, includes constructing 1,019 residential lots, 138 common lots, interior roadways, underground utility services, and other supporting infrastructure. The construction activities would reroute 2,150 linear feet of the Deer Flat Caldwell Canal and impact 618.5 linear feet of the Forest Canal across six different locations.
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 addendum and supporting materials are available for public review at DEQ’s State Office (1410 N. Hilton St. Boise, Idaho 83706), DEQ’s Boise Regional Office (1445 N. Orchard St. Boise, Idaho 83706), and on DEQ’s website. Written comments will be accepted through October 3, 2025, at 5 p.m. Mountain Time.
