PROPOSED DISCHARGE OF DREDGED OR FILL MATERIAL TO ATHERTON CREEK AND WETLANDS

The Wyoming Department of Environmental Quality (WDEQ) has received a request from Western Federal Lands Highway Division (WFLHD) for State certification of U.S. Army Corps of Engineers Nationwide Permit #14, for discharge of dredged or fill material to Atherton Creek and unnamed wetlands within Grand Teton National Park, Wyoming. These segments of Atherton Creek and unnamed wetlands are designated Class 1. Point source discharges to Class 1 waters are prohibited except for storm water and construction related discharges. This certification will require meeting the provisions in Chapter 1, Section 7(b) of the WDEQ Water Quality Rules and Regulations, which allows these discharges under certain circumstances.

The project involves rehabilitation of approximately 3.75 miles of the Gros Ventre Road from the National Forest Boundary to the Atherton Campground near Jackson, WY. Proposed activities include road widening, removing and replacing culverts, placing riprap at the outlets of replaced culverts, ditch reconstruction, repaving, and installation of road underdrains. To do this, a total of 192 cubic yards (CY) of material will be placed in Atherton Creek and nearby wetlands. This will result in 0.067 acre of permanent impact to wetlands.

Requests for information about the proposed water quality certification 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 December 26, 2019 to be considered. Phone or email comments will not be accepted.
