PROPOSED TEMPORARY TURBIDITY INCREASE IN FISH CREEK IN TETON COUNTY

Nelson Engineering has requested a waiver from the Wyoming Department of Environmental Quality, Water Quality Division (WDEQ/WQD) for a temporary increase in turbidity in Fish Creek (Section 22; T41N, R117W) in Teton 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 sixty (60) 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 received a 404 permit from the U.S. Army Corps of Engineers for the project. Proposed activities include demolishing an existing bridge across Fish Creek and replacing it with a new one.

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 October 16, 2019 (or faxed to 307-635-1784) to be considered. Phone or email comments will not be accepted.
