==August 2009: TVA considering shutting down some aging coal plants==

On August 24, 2010 TVA announced that it will retire 9 coal-fired generating units totalling about 1,000 megawatts of capacity at three locations beginning in fiscal year 2011: [[Shawnee Fossil Plant]] Unit 10 in Kentucky, [[John Sevier Fossil Plant]] Units 1 and 2 in Tennessee, and [[Widows Creek Fossil Plant]] Units 1-6 in Alabama, including six units at the [[Widows Creek Fossil Plant]]. In addition TVA stated that it will going to eliminate 200 jobs at these plants starting in 2011, but the workers will be placed in other positions within TVA. CEO [[Tom D. Kilgore]] said that TVA would replace the sidelined coal power with greater reliance on nuclear power and energy efficiency.<ref>[http://www.tva.com/news/releases/julsep10/coal_plants.html "TVA to idle 9 coal-fired units,"] Tennessee Valley Authority press release, August 24, 2010.</ref>

A report released by EarthJustice and the Sierra Club in early February 2011 stated that there are many health threats associated with a toxic cancer-causing chemical found in coal ash waste called [[hexavalent chromium]]. The report specifically cited 29 sites in 17 states where the contamination was found. The information was gathered from existing EPA data on coal ash and included locations in Alabama, Arkansas, Delaware, Florida, Illinois, Indiana, Minnesota, Massachusetts, North Carolina, North Dakota, Nevada, Ohio, Oklahoma, Pennsylvania, Tennessee, Virgina and Wisconsin. In Alabama, the TVA [[Colbert Fossil Plant]] in Tuscambia and the TVA [[Widows Creek Fossil Plant]] in Stevenson were both reported as having high levels of chromium seeping from unlined retention ponds.<ref>[http://earthjustice.org/sites/default/files/CoalAshChromeReport.pdf "EPA’s Blind Spot: Hexavalent Chromium in Coal Ash"] Earthjustice & Sierra Club, February 1, 2011.</ref>
