The Finding of No Significant Impact (FONSI) was signed by the Director of Civil Works on June 27, 2022 for the Federal Participation in Watercraft Inspection Stations, Updated Integrated Letter Report and Programmatic Environmental Assessment, Columbia River Basin (LR/PEA). In compliance with the National Environmental Policy Act, the Corps produced the Updated LR/PEA to evaluate the potential economic and environmental effects of including the states of Nevada and Wyoming in the current and successful federal cost-share program of establishing and maintaining watercraft inspection stations in the Columbia River Basin to help prevent the spread of aquatic invasive species, specifically zebra and quagga mussels. The current program is operated in Idaho, Montana, Oregon, and Washington. Expansion of the program to Nevada and Wyoming will help to prevent the spread of aquatic invasive species to reservoirs in the Columbia River Basin, operated by the U.S. Army Corps of Engineers.
