PROPOSED DISCHARGE OF DREDGED OR FILL MATERIAL TO THE SNAKE RIVER AND ADJACENT WETLANDS

The Wyoming Department of Environmental Quality (WDEQ) has received requests from Biota Research and Consulting, Inc. and Intermountain Aquatics, Inc. on behalf of Teton County for State certification of U.S. Army Corps of Engineers Nationwide Permits #3 and #42, for discharge of dredged or fill material to the Snake River and adjacent wetlands as part of improvements to the Wilson Boat Ramp near Wilson, Wyoming. The Snake River upstream from the U.S. Highway 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 include placement of a 6-inch lift of alluvium on top of existing rip rap to fill voids and improve safety at the boat ramp access site. A total of 47 cubic yards (CY) of material would be used of which only 24 CY will be placed below the ordinary high water mark. Other proposed activities include construction of a new entrance road, parking area, pathways and restrooms. One road crossing and grading around the perimeter of the developed area would result in a loss of 0.02 acre of wetland adjacent to the Snake River. Per Teton County’s regulations, impacted wetlands would be mitigated onsite at a ratio of 2:1.

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 October 10, 2018 to be considered.  Phone or email comments will not be accepted.
