The Wyoming Department of Environmental Quality (WDEQ) has received a request from the National Park Service for State certification of U.S. Army Corps of Engineers (USACE) Nationwide Permit #27, for discharge of dredged or fill material to the Gros Ventre River in Grand Teton National Park, Wyoming. The purpose of the project is to remove rock from the Gros Ventre River floodplain that was deposited following failure of the adjacent Savage Ditch in 2017. The project also involves repair of the Savage Ditch. This segment of the Gros Ventre River is designated Class 1 where point source discharges are prohibited except for storm water and construction related discharges. This certification will require meeting the provisions in Chapter 1, Section 7(b) of the WDEQ Water Quality Rules and Regulations, which allows these discharges under certain circumstances. Proposed activities include the removal of approximately 50 cubic yards (CY) of rock from the floodplain. This excavated material combined with approximately 150 CY of imported aggregate will be used to repair the Savage Ditch. No wetlands will be impacted.
Requests for information about the proposed water quality certification should be directed to Eric Hargett by email ([email protected]) or phone (307-777-6701). Written comments must be addressed to Eric Hargett, Wyoming DEQ/WQD, 200 W. 17th Street ? 4TH floor, Cheyenne, WY, 82002, and be postmarked on or before 5:00 p.m. on July 6, 2022 to be considered. Electronic comments may only be submitted through and accepted by the Wyoming DEQ comment portal provided at http://wq.wyomingdeq.commentinput.com/. Phone comments will not be accepted.
