The US Forest Service has requested a waiver from the Wyoming Department of Environmental Quality, Water Quality Division (WDEQ/WQD) for a temporary increase in turbidity in Mill Creek (Section 7; T29N, R101W) 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 five (5) 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. The applicant has applied for a 404 permit from the U.S. Army Corps of Engineers for the project. Proposed activities include the installation of beaver dam analogs to help reconnect the stream to its floodplain.

Requests for related information and documents about the proposed temporary turbidity increase should be directed to Bret Callaway by email ([email protected]) or phone (307-777-5802).
