The Idaho Department of Environmental Quality (DEQ) is seeking comment on a draft 401 water quality certification for the Schweitzer Engineering Laboratories (SEL) Moscow Building #2 project.
SEL proposes constructing a new building and parking lot in Moscow, Idaho, with access to Reisenauer Road. Site improvements include relocating and realigning the South Fork Palouse River-Gnat Creek to Idaho/Washington border to be closer to Reisenauer Road and installing two 36-foot culvert pipes for creek continuity.
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, ID 83706), DEQ’s Lewiston Regional Office (1118 F St. Lewiston, ID 83501), and on DEQ’s website. Written comments will be accepted through July 3, 2026, at 4 p.m. Pacific Time.
