PROPOSED TEMPORARY TURBIDITY INCREASE IN THE WIND RIVER IN FREMONT COUNTY

Kilroy 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 Wind River (Section 20; T3N, R1W) in Fremont 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 sixty (60) 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. A 404 Permit has already been obtained from the U.S. Army Corps of Engineers for the project. Proposed activities include grading and temporary installation of a coffer dam to stabilize and restore an actively eroding bank.

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 January 3, 2019 (or faxed to 307-635-1784) to be considered. Phone or email comments will not be accepted.
