PROPOSED TEMPORARY TURBIDITY INCREASE IN THE GROS VENTRE RIVER IN TETON COUNTY

The Federal Highway Administration has requested a waiver from the Wyoming Department of Environmental Quality, Water Quality Division (WDEQ/WQD) for a temporary increase in turbidity in the Gros Ventre River (Section 24; T42N, R116W) in Teton County. Activity in cold water streams is normally limited to a ten (10) NTU increase over background. Approval of this request would allow an exceedance of this limit for up to thirty (30) working days, subject to monitoring and reporting. This activity will follow the procedures in Chapter 1, Section 23(c)(ii), of the WDEQ Water Quality Rules and Regulations, which allow for temporary elevated levels of turbidity in certain circumstances. An application for a 404 Permit from the U.S. Army Corps of Engineers has been submitted for the project. Proposed activities include the installation of rip rap barbs within the channel to armor the bank of Gros Ventre Road.

Requests for related information and documents about the proposed temporary turbidity increase should be directed to Bret Callaway by email (bret.callaway@wyo.gov) or phone (307-777-5802). Comments must be addressed to Bret Callaway, Wyoming DEQ/WQD, 200 West 17th Street, 4th Floor, Cheyenne, WY 82002, and postmarked before 5:00 p.m. on February 27, 2019 (or faxed to 307-635-1784) to be considered. Phone or email comments will not be accepted.
