PROPOSED TEMPORARY TURBIDITY INCREASE IN THE NORTH PLATTE RIVER

The Wyoming Department of Environmental Quality (WDEQ) has received a request from the City of Casper, for a temporary increase in turbidity in the North Platte River in Casper, Wyoming. The temporary increase in turbidity is associated with the proposed second phase of stream restoration in the North Platte River near 1st Street.

Activity in cold water streams like the North Platte 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 seventy-one (71) 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 Engineer 404 permit for the project.

Requests for information about the proposed turbidity increase should be directed to Eric Hargett by email (eric.hargett@wyo.gov) 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 September 28, 2020 to be considered. Phone or email comments will not be accepted. Para español, visite deq.wyoming.gov.
