PROPOSED TEMPORARY TURBIDITY INCREASE IN NORTH FORK CROW CREEK IN LARAMIE COUNTY

The City of Cheyenne Board of Public Utilities has requested a waiver from the Wyoming Department of Environmental Quality, Water Quality Division (WDEQ/WQD) for a temporary increase in turbidity in North Fork Crow Creek (Section 36, T15N, R70W) in Laramie County.  Activity in cold water streams is normally limited to a ten NTU increase over background.  Approval of this request would allow an exceedance of this limit for up to 180 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. A 404 Permit from the U.S. Army Corps of Engineers is not required for this project. Proposed activities include inspection of the dam outlet pipes and drain valve and pipe.

Requests for related information and documents about the proposed temporary turbidity increase should be directed to Cathy Norris by email (cathy.norris@wyo.gov) or phone (307-777-6372).  Comments must be addressed to Cathy Norris, Wyoming DEQ/WQD, 200 West 17th  Street, 4th Floor, Cheyenne, WY 82002, and postmarked before 5:00 p.m. on January 25, 2018 (or faxed to 307-635-1784) to be considered.  Phone or email comments will not be accepted.
