Proposed temporary turbidity increase in Pine Creek


PINEDALE, Wyo. (KIFI) - The Wyoming Department of Environmental Quality (WDEQ) has received a request from Alder Environmental, LLC for a temporary increase in turbidity in Pine Creek in Pinedale, Wyoming. The temporary increase in turbidity is associated with bank stabilization.

Approval of this request would allow an exceedance of this limit for up to twenty-eight (28) 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 secured a U.S. Army Corps of Engineers 404 permit for the project.

Requests for information about the proposed temporary turbidity increase should be directed to Eric Hargett by email ( or phone (307-777-6701).
