PROPOSED TEMPORARY TURBIDITY INCREASE IN UPPER CROW CREEK, UPPER LODGEPOLE CREEK, LARAMIE RIVER-SPRING CREEK, AND HARNEY CREEK IN ALBANY COUNTY

The United States Forest Service has requested a waiver from the Wyoming Department of Environmental Quality, Water Quality Division (WDEQ/WQD) for a temporary increase in turbidity in Upper Crow Creek, Upper Lodgepole Creek, Laramie River-Spring Creek, and Harney Creek (T14N-15N, R71W-72W) in Albany 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 three 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. An application for a 404 Permit from the U.S. Army Corps of Engineers has been submitted for this project. The City of Cheyenne, responsible for the public water supply intake downstream of this project, has been notified. Proposed activities include decommissioning approximately 62 miles of roads to a natural vegetated state.

Requests for related information and documents about the proposed temporary turbidity increase should be directed to Bret Callaway by email (bret.callaway@wyo.gov) or phone (307-777-5802).  Comments must be addressed to Bret Callaway, Wyoming DEQ/WQD, 200 West 17th  Street, 4th Floor, Cheyenne, WY 82002, and postmarked before 5:00 p.m. on June 27, 2018 (or faxed to 307-635-1784) to be considered. Phone or email comments will not be accepted.
