Colorado Coop Sues EPA Over New Emissions Standards

Tri-State Generation and Transmission Association, Inc. has filed suit in the U.S. Court of Appeals for the District of Columbia Circuit, challenging the U.S. Environmental Protection Agency’s new mercury and air-toxics emissions standards for coal-fired power plants.  The coop, Colorado’s second-largest power utility, serves some 1.5 million customers in Colorado, New Mexico, Wyoming and Nebraska.  Tri-State claims the EPA standards, which took effect Monday, will drive up electricity costs because of expensive technology needed to meet the rules.  Several other entities, including the American Public Power Association, the National Mining Association and the Utility Air Regulatory Group, have also filed suit.  The new emissions standards are the first federal rules that require coal- and oil-fired power plants to limit their emissions of these pollutants.  The Denver Business Journal has the full story.
