Accepting comments from June 18, 2024, through July 9, 2024.

The Idaho Department of Environmental Quality (DEQ) seeks comment on a draft 401 water quality certification for Rainey Creek trail crossing improvements.

This project will replace five ford type stream crossings in the Rainey Creek watershed with ATV trail bridges. The proposed activities include, but not limited to, installing five timber bridges on rock filled gabion baskets with timber sills and abutments. All bridge features will be placed outside of the ordinary high-water mark. Trail rerouting for approximately 546 ft. Streambank restoration and restoration of existing ford crossings. In total, the proposed activities will result in 135.9 cubic yards of material to be discharged and 3,941 square feet of stream and wetland impacts.

Based upon review of the federal permit application, readily available water quality related materials, and certification request in accordance with the Clean Water Act § 121.5 (b) and (c) and 121.7 (c), DEQ, certifies that if the permittee complies with the terms and conditions imposed by the 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 certification materials are available for public review at DEQ’s State Office (1410 N. Hilton Street, Boise, Idaho) and on DEQ’s Public Comment Opportunities page. Written comments will be accepted through July 9, 2024, at 5 p.m. (MDT). Submit comments electronically via DEQ’s public comment form or by mail or email:
