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

Alder Environmental, LLC 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 34; T42N, R112W) 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 twenty five (25) 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 has been submitted to the 404 Permit from the U.S. Army Corps of Engineers for the project. Proposed activities include the installation of a vegetated toe boulder bank revetment and restoration of uplands that were lost to erosion.

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 October 16, 2018 (or faxed to 307-635-1784) to be considered. Phone or email comments will not be accepted.
