PROPOSED DISCHARGE OF DREDGED OR FILL MATERIAL TO THE GROS VENTRE RIVER

The Wyoming Department of Environmental Quality (WDEQ) has received a request from Western Federal Lands Highway Division (WFLHD) for State certification of U.S. Army Corps of Engineers Nationwide Permit #13, for discharge of dredged or fill material to the Gros Ventre River within Grand Teton National Park, Wyoming. This segment of the Gros Ventre River is designated Class 1. Point source discharges to Class 1 waters 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 realignment of a 1,800-foot section of the Gros Ventre Road which includes adding bank protections and constructing five stream barbs along the adjacent Gros Ventre River to protect and re-orient flows away from the road embankment. A total of 1,575 cubic yards (CY) of redistributed alluvium and 1,650 CY of rip-rap will be used to re-shape and armor the embankment along with construction of the stream barbs.

Requests for information about the proposed water quality certification should be directed to Eric Hargett by email (eric.hargett@wyo.gov) or phone (307-777-6701). 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 January 16, 2019 to be considered. Phone or email comments will not be accepted.
