The U.S. Army Corps of Engineers, Walla Walla District (Corps) released the Draft Finding of No Significant Impact (FONSI) and Environmental Assessment (EA) for flowering rush control in the States of Washington, Idaho, Oregon, and Montana. Flowering rush is an aquatic invasive plant species, non-native to the Pacific Northwest.
The Corps proposes to share flowering rush control treatment costs with the Pacific States Marine Fish Commission to treat infestations on non-Federal lands. The goal of treatment is to prevent and/or minimize the impacts of flowering rush invasion on habitat, irrigation, and recreation. The aim is to eradicate known and future flowering rush populations and provide continued subsequent control at a much-reduced effort.
The Corps’ participation in this project is authorized under Section 1039(d) of the Water Resources Reform and Development Act of 2014 (Public Law 113-121) and Section 1178 of the Water Infrastructure Improvements for the Nation Act of 2016 (Public Law 114-322).
The 30-day comment period was from June 24, 2019 to July 24, 2019 and has since closed. All information and comments submitted will be included in the permanent public record.
The Draft FONSI and EA are available in electronic form below.
