Public Notice: PROPOSED TEMPORARY TURBIDITY INCREASE IN THE LARAMIE RIVER

The Wyoming Department of Environmental Quality (WDEQ) has received a request from Dietzler Construction, for a temporary increase in turbidity in the Laramie River west of Wheatland, Wyoming. The temporary increase in turbidity is associated with proposed rehabilitation of the Tunnel Dam which includes resurfacing concrete structures, enlarging the outlet works and sluiceway, and repairing wing walls and embankments.

Activity in cold water streams like the Laramie 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 ten (10) 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 project falls under the agricultural exemption whereby a U.S. Army Corps of Engineer 404 permit is not required.

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 August 12, 2020 to be considered. Phone or email comments will not be accepted. Para español, visite deq.wyoming.gov.
