PROPOSED TEMPORARY TURBIDITY INCREASE IN THE SNAKE RIVER IN LINCOLN COUNTY

Bridger-Teton National Forest has requested a waiver from the Wyoming Department of Environmental Quality, Water Quality Division (WDEQ/WQD) for a temporary increase in turbidity in the Snake River (Section 1, T37N, R117W) in Lincoln County.  Activity in cold water streams is normally limited to a ten NTU increase over background.  Approval of this request would allow an exceedance of this limit for up to 20 (twenty) 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 this project. Proposed activities include repair and extension of two boat ramps and repair and revegetation of the stream bank adjacent to and between the ramps.

Requests for related information and documents about the proposed temporary turbidity increase should be directed to Cathy Norris by email (cathy.norris@wyo.gov) or phone (307-777-6372).  Comments must be addressed to Cathy Norris, Wyoming DEQ/WQD, 200 West 17th  Street, 4th Floor, Cheyenne, WY 82002, and postmarked before 5:00 p.m. on October 24, 2017 (or faxed to 307-635-1784) to be considered.  Phone or email comments will not be accepted.
