PROPOSED DISCHARGE OF DREDGED OR FILL MATERIAL TO THE SNAKE RIVER

The Wyoming Department of Environmental Quality (WDEQ) has received a request from Biota Research and Consulting, Inc. for State certification of U.S. Army Corps of Engineers (USACE) Regional General Permit 19922202 Version 6 (RGP 9202-06), for discharge of dredged or fill material to the Snake River near Moran, Wyoming. The purpose of this project is to upgrade the existing Pacific Creek Landing boat ramp on the Snake River within Grand Teton National Park. All waters within Grand Teton National Park are designated Class 1 waters where point source discharges 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. Proposed activities include widening the ramp to two lanes and installing precast concrete interlocking planks, replacing the existing culverts with a three-sided concrete box culvert, expanding ramp access, repair retaining walls and stabilizing banks. To do this, a total of 198 cubic yards (CY) of material will be used to construct the improvements that will result in permanent impacts to 0.002 acre of wetland adjacent to the Snake River.

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 February 26, 2020 to be considered. Phone or email comments will not be accepted.
