→Proposed Plant Retirements: added Colbert retirement
On July 26, 2010, a federal appeals court reversed a judge's ruling in [[North Carolina v. TVA]] requiring prompt installation of upgraded emission controls at four TVA coal-fired power plants, three in Tennessee and one in Alabama. U.S. District Judge Lacy Thornburg had ordered the accelerated cleanup at the TVA plants, ruling that emissions affecting air quality in North Carolina's scenic western mountains were a "public nuisance." A three-judge panel of the 4th U.S. Circuit Court of Appeals overturned the decision. Appeals court Judge J. Harvie Wilkinson III wrote that allowing the ruling to stand would undermine the nation's "carefully created" [[Clean Air Act]] regulatory scheme. North Carolina then sought a rehearing.<ref>[http://blog.al.com/spotnews/2010/07/federal_appeals_court_blocks_r.html "Federal appeals court blocks ruling for fast-track emission controls at 4 TVA coal-fired plants"] al.com, July 26, 2010.</ref>
===July 2013: [[Colbert Fossil Plant]] Units 1-4 to be idled or retired in 2016===
In July 2013 TVA announced plans to idle or remove from service [[Colbert Fossil Plant]] units 1-4 starting June 30, 2016. The plans are the result of a 2011 Consent Decree arising out of consolidated litigation brought by several states and environmental groups for violations of the Clean Air Act. Under the decree, TVA was required to notify EPA of its plan for controlling air pollution at units 1-4 by June 30, 2013. Rather than installing new equipment, TVA opted to idle or retire the plants. According to the Southern Alliance for Clean Energy, unit 5 of the plant, which operated at only 15% of capacity in 2012, appeared also to be heading toward retirement.<ref>Angela Garrone, [http://blog.cleanenergy.org/2013/07/08/tva-announces-plans-to-idle-colbert-coal-plant-units/ "TVA announces plans to idle Colbert Coal Plant units,"] Southern Alliance for Clean Energy blog, July 8, 2013</ref>
