On Friday, the U.S. Court of Appeals for the District of Columbia Circuit vacated the Surface Transportation Board's ("Board's") authorization for the construction of a new railroad line in Utah that was designed to support new crude oil wells in the Uinta Basin. In reaching that outcome, the D.C. Circuit agreed with many of the points we raised in an amicus brief prepared on behalf of a coalition of Colorado cities, towns, and counties that opposed the railroad and the faulty environmental analysis underlying the Board's authorization. For instance, the Court rejected as "utterly unreasoned" the Board's decision to forgo an analysis of the increased wildfire risk in Colorado caused by increased rail traffic because that traffic is not a new kind of "ignition source." The Court's decision, a copy of which is available here, is a victory for our clients and all those communities situated along Colorado's I-70 corridor.
