Public Notice: Water Quality Certification for South Fork Little Wind River Intake Project on the Wind River Indian Reservation
Summary
The U.S. Environmental Protection Agency (EPA) received a request from the U.S. Army Corps of Engineers (USACE) for a Clean Water Act (CWA) Section 401 water quality certification (WQC). Section 401(a)(1) of the Clean Water Act requires applicants for Federal permits and licenses that may result in any discharge into waters of the United States to obtain certification or waiver from the certifying authority where the discharge would originate.
The EPA acts as the certifying authority in areas of Indian country on behalf of those Tribes that have not received treatment in a similar manner as a state (TAS) for Section 401, in this case the Eastern Shoshone Tribe and the Northern Arapaho Tribe of the Wind River Indian Reservation.
The EPA will act on this certification request by either: (1) granting certification; (2) granting certification with conditions; (3) denying certification; or (4) expressly waiving certification consistent with CWA Section 401 and the EPA’s implementing regulations at 40 CFR Part 121.
The proposed project would be covered under USACE CWA Section 404 Nationwide Permit (NWP) 58 which authorizes utility line activities for water and other substances and addresses impacts to Waters of the U.S. from pipeline activities that are not related to oil, natural gas, or petrochemicals.
EPA is requesting comments on its Clean Water Act section 401 water quality certification for this proposed project.
Project Description
The proposed project will construct a new surface water intake on the north bank of the South Fork of the Little Wind River. Work to be completed under the ordinary high water mark (OHWM) includes excavation for the concrete intake structure and placement of gabions to protect the intake structure. A cofferdam will be used to dewater the area immediately surrounding the intake structure. Gabions will be placed to either side of the intake structure, backfilled landward and existing riprap from excavated areas will be placed along the bottom of the channel at the base of the gabion baskets. Construction will occur during low flow. The project will result in 0.1 acre of temporary impacts due to construction access and placement of the cofferdam, and 0.004 acres of permanent impacts from the placement of the intake structure and gabion baskets in the South Fork of the Little Wind River.
