CORRECTION: PROPOSED TEMPORARY TURBIDITY INCREASE IN MCCORMICK CREEK IN SHERIDAN COUNTY

Tad Tipton has requested a waiver from the Wyoming Department of Environmental Quality, Water Quality Division (WDEQ/WQD) for a temporary increase in turbidity in McCormick Creek (Section 35; T55N, R84W) in Sheridan County. Activity in cold water streams is normally limited to a fifteen (15) NTU increase over background. Approval of this request would allow an exceedance of this limit for up to twenty (20) 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 the project. Proposed activities include the installation of a culvert to cross McCormick Creek and associated erosion control structures.

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 April 23, 2019 (or faxed to 307-635-1784) to be considered. Phone or email comments will not be accepted.
