On February 4, 2009, the U.S. Justice Department and the Environmental Protection Agency filed a clean air lawsuit against Westar, claiming the company updated a coal plant in Kansas without installing modern pollution controls. The suit alleges that Westar's 1,857 MW [[Jeffrey Energy Center]] has violated the Clean Air Act for over a decade.<ref name="reu">[http://uk.reuters.com/article/marketsNewsUS/idUKN0431945320090205 "U.S. files clean air lawsuit against Westar Energy,"] Reuters, February 5, 2009.</ref>

On September 29, 2009, the [[Sierra Club]] announced it was planning to file a request in federal court to intervene in the lawsuit.
