One version of a proposed 500-plus-mile water pipeline from southwestern Wyoming to Colorado’s Front Range was dealt a blow by a federal regulatory agency that found the application deficient on Wednesday. The Federal Regulatory Energy Commission (FERC) sent a letter to Fort Collins businessman Aaron Million requesting more information within a month, but FERC officials also appeared to have serious jurisdictional questions. “Because the Commission would only have jurisdiction with regard to the proposed hydroelectric development, which is only one component of the proposed 501-mile-long water supply pipeline project, construction of substantial parts of the overall project may require permits from other federal agencies,” FERC officials wrote.
