Cumo Exploration Project (previously listed as Cumo 2007 Project)

The CuMo Exploration Supplemental Decision Notice/FONSI was signed on 9/30/2015. Alternative B was selected for implementation, which allows construction of up to 10.2 miles of temporary roads, up to 137 drill pads and 259 drill holes. On January 15, 2016, a lawsuit was filed against this project: Idaho Conservation League et al. v. United States Forest Service (1:16-CV-0025-EJL). On July 11, 2016 the U.S. District Court for the District of Idaho issued a Memorandum of Decision and Order which vacated a portion of the supplemental decision based upon Sacajawea?s bitterroot (LESA). The Forest is moving forward with preparation of a second supplemental EA to address the 2016 Court order requiring the re-evaluation of the LESA?s baseline to determine whether decisions and conclusions with regard to LESA documented in the 2015 SEA and DN/FONSI are different or remain the same in light of the effects resulting from the 2014 Grimes Fire, as well as the 2016 Pioneer Fire. In addition, the supplement will address changed conditions resulting from the 2016 Pioneer Fire for all resources identified as affected in the 2017 Supplemental Information Report (SIR) completed for this project. Please see the 2018 CuMo Exploration Project webpage for current information on this project.
