Abstract: The US Army Corps of Engineers, Walla Walla District (Corps), proposes to implement a Rapid Response Action Plan for the eradication of potential zebra (Dresissena polymorhpa) and quagga mussel [D. bugensis (collectively referred to as dreissenids)] infestations in the Columbia River Basin (CRB), as well as across infested waterbodies in the states of Washington, Oregon, Idaho, and Montana. Authorized through Section 104 of the River and Harbor Act of 1958, as amended by Section 1039(d) of the Water Resources Reform and Development Act of 2014 and Section 1178 of Water Infrastructure Improvements of the Nation Act of 2016, the Corps began laying the ground work for the Plan in 2017 by developing the Final Integrated Letter Report and Programmatic Environmental Assessment for Federal Participation in Watercraft Inspection Stations, Columbia River Basin. The potential is high for dreissenid invasion in the four-state area (FSA - Idaho, Montana, Oregon, and Washington), as recreational watercraft from across the country transport invasive species into other waterbodies. For example, between 1993 and 1999, the California Department of Food and Agriculture found live and dead zebra mussels on 18 different trailered watercraft that were inspected coming into the state. For this reason, inspection stations are now common throughout the northwest. Considering past data from California alone, it is assumed that dreissenids being introduced into the CRB at some point is not only possible, but highly probable. This Environmental Assessment was prepared in accordance with Engineer Regulation 200-2-2, Procedures for Implementing NEPA, and the Council on Environmental Quality Regulations for Implementing the Procedural Provisions of the National Environmental Policy Act, Title 40 Code of Federal Regulations, Part 1500-1508. The objective of the EA is to evaluate potential environmental effects of the proposed Plan and determine if significant effects would result. If such effects are less than significant, a Finding of No Significant Impact would be issued and the Corps would proceed with the proposed action. If the environmental effects are determined to be significant, an Environmental Impact Statement would be prepared before a decision is reached on whether to implement the proposed action. Applicable laws under which these effects would be evaluated include but are not limited to, NEPA, the Endangered Species Act, the Clean Water Act, the Clean Air Act, and the National Historic Preservation Act.
