PROPOSED DISCHARGE OF DREDGED OR FILL MATERIAL TO THE NORTH PLATTE RIVER

The Wyoming Department of Environmental Quality (WDEQ) has received a request from the United States Department of Agriculture-Natural Resources Conservation Service (NRCS) on behalf of Ryan Ranches, Inc. for State certification of U.S. Army Corps of Engineers Nationwide Permit #27, for discharge of dredged or fill material along the North Platte River for purposes of streambank stabilization/rehabilitation, south of Saratoga, Wyoming. The North Platte River from the confluence with Sage Creek upstream to the Colorado/Wyoming state line 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 1,500-foot reach of the North Platte River include re-distribution of bed material to create a stable channel, construct 600-feet of bankfull bench and integrate 550-foot of toe-wood revetment. Four rock vanes would also be installed to further promote stream bank stability. Woody riparian vegetation would be planted in the project area to provide additional stability for the rock vanes and toe-wood. Approximately 1,000 cubic yards (CY) of rock would be required for the rock vanes. 

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 August 21, 2018 to be considered.  Phone or email comments will not be accepted.
