Public Notice: PROPOSED TEMPORARY TURBIDITY INCREASE IN THE TONGUE RIVER

The Wyoming Department of Environmental Quality (WDEQ) has received a request from the Town of Dayton, for a temporary increase in turbidity in the Tongue River in Dayton, Wyoming. The temporary increase in turbidity is associated with proposed improvements to the Dayton wastewater treatment plant.

 Activity in cold water streams like the Tongue 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 thirty (30) 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 (eric.hargett@wyo.gov) 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 December 6, 2021 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.
