PROPOSED TEMPORARY TURBIDITY INCREASE IN THE NORTH PLATTE RIVER IN PLATTE COUNTY

Bridger Pipeline LLC has requested a waiver from the Wyoming Department of Environmental Quality, Water Quality Division (WDEQ/WQD) for a temporary increase in turbidity in the North Platte River (Section 9; T26N, R65W) in Platte County. Activity in cold water streams 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) 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 submitted an application for a 404 permit from the U.S. Army Corps of Engineers for the project. Proposed activities include boring 60’ under the North Platte River bed to install a 20” steel pipeline.

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 January 7, 2020 (or faxed to 307-635-1784) to be considered. Phone or email comments will not be accepted.
