PROPOSED DISCHARGE OF DREDGED OR FILL MATERIAL TO THE SNAKE RIVER

The Wyoming Department of Environmental Quality (WDEQ) has received a request from the National Park Service for State certification of U.S. Army Corps of Engineers Nationwide Permit #18, for discharge of dredged or fill material to the Snake River at three separate locations within Grand Teton National Park, Wyoming. The Snake River within the national park 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 necessary biannual maintenance at the Deadman’s Bar, Moose Landing and Pacific Creek boat ramps along the Snake River. Maintenance will involve removal of accumulated sediment at the boat ramps that will be discharged back into the river. Sediment discharged from each ramp will not exceed 25 cubic yards (CY).

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 July 24, 2019 to be considered. Phone or email comments will not be accepted.
