The U.S. Court of Appeals for the District of Columbia Circuit dismissed May 28 a suit filed by the Sierra Club over the Holcomb Expansion Project, a coal-fired power plant in Kansas. The lower court ruled that the Department of Agriculture Rural Utilities Service must complete an environmental assessment, and plant operator Sunflower Electric Power Corp. appealed the decision. The appellate court ruled that it could not consider the lawsuit since the lower court order is not final.
