Accepting comments from February 20, 2025, through March 13, 2025.

BOISE – The Idaho Department of Environmental Quality (DEQ) is seeking comment on a draft water quality certification for the ​Public Avenue Corridor safety improvement project.

This project aims to enhance safety at the intersection of Polk Avenue and Public Avenue in Moscow, Idaho. The proposed project would involve moving roadside drainage swales, creating a navigable corridor for vehicles and pedestrians.

Based upon review of the federal ​permit​ application, readily available water quality related materials, and certification request in accordance with 40 C.F.R. §§ 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 review on DEQ’s Public Comment Opportunities web page. Written comments will be accepted through March 13, 2025, at 5 p.m. Mountain Time. Submit comments electronically using the form below or by mail or email to:
