Public Notice: PROPOSED TEMPORARY TURBIDITY INCREASE IN SPREAD CREEK

The Wyoming Department of Environmental Quality (WDEQ) has received a request from the National Park Service, for a temporary increase in turbidity in Spread Creek near Moran, Wyoming in Grand Teton National Park. The temporary increase in turbidity is associated with proposed stream bank stabilization and diversion maintenance activities.

Activity in cold water streams like Spread Creek 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 twenty (20) total 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 applied for a U.S. Army Corps of Engineer 404 permit for the project.

Requests for information about the proposed turbidity increase should be directed to Eric Hargett by email (eric.hargett@wyo.gov) or phone (307-777-6701). Comments must be addressed to Eric Hargett, Wyoming DEQ/WQD, 200 W. 17th Street – 4TH floor, Cheyenne, WY, 82002, and be postmarked on or before 5:00 p.m. on September 16, 2020 to be considered. Phone or email comments will not be accepted. Para español, visite deq.wyoming.gov.
