Temporary turbidity increase in the Middle Fork Popo Agie River request submitted

The Wyoming Department of Environmental Quality (WDEQ) has received a request from Environmental Restoration for a temporary increase in turbidity in the Middle Fork Popo Agie River in Lander, Wyoming. The temporary increase in turbidity is associated with proposed removal of a retention wall at the Maverick Station at 135 E. Main Street.

Activity in cold water streams like the Middle Fork Popo Agie 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 three (3) 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 and Regulations, 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 turbidity increase should be directed to Eric Hargett by email ([email protected]) or phone (307-777-6701). 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 October 16, 2020 to be considered. Phone or email comments will not be accepted. Para español, visite deq.wyoming.gov.
