PROPOSED DISCHARGE OF DREDGED OR FILL MATERIAL TO THE SNAKE RIVER

The Wyoming Department of Environmental Quality (WDEQ) has received a request from the U.S. Army Corps of Engineers (USACE), Walla Walla, Washington District for State certification of USACE Nationwide Permit #3, for discharge of dredged or fill material along the existing Snake River levee system north of Wilson, Wyoming. The Snake River upstream of the U.S. Hwy 22 bridge is 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.  

Proposed activities within a combined 1,070-foot reach of the right bank of the Snake River include repairing the existing levee slope and toe along with construction of 11 rock barbs to minimize damages to the levee during high flows. Approximately 496 cubic yards (CY) of rock rip-rap would be required for the levee repair and 414 CY for the rock barbs. 

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 September 11, 2018 to be considered.  Phone or email comments will not be accepted.
