The Wyoming Department of Environmental Quality (WDEQ) has received a request from Steady Stream Hydrology, for a temporary increase in turbidity in the Bighorn River in Thermopolis, Wyoming. The temporary increase in turbidity is associated with proposed bank stabilization.
Activity in cold water streams like the Bighorn River 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 five (5) total 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, which allow for temporary elevated levels of turbidity in certain circumstances. The applicant has applied for a U.S. Army Corps of Engineer 404 permit for the project.
Requests for information about the proposed temporary turbidity increase should be directed to Eric Hargett by email ([email protected]) or phone (307-777-6701). Written 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 August 11, 2022 to be considered. Electronic comments may only be submitted through and accepted by the Wyoming DEQ comment portal provided at http://wq.wyomingdeq.commentinput.com/. Phone comments will not be accepted.
