On August 28, the Center for Biological Diversity stated that it would file a lawsuit against the Environmental Protection Agency for missing national ambient air quality standards for fine particulate matter deadlines. Seven states did not submit final strategic plans to implement the new fine particulate matter standards by the deadline set in the Clean Air Act. Accordingly, the Environmental Protection agency missed the June 14 statutory deadline for releasing formal findings on the state implementation strategies, which would trigger a two-year clock for the agency to devise a federal implementation plan. Furthermore, the notice cites other examples of missed statutory deadlines dating back to 2012.
