Issuing agencies

Abstract

In accordance with the Clean Air Act, as amended (CAA or the Act), notice is given of a proposed consent decree in Center for Biological Diversity, et al. v. Regan, No. 4:21-cv-06166-JST. On August 11, 2021, Plaintiffs Center for Biological Diversity, Center for Environmental Health, and Sierra Club (collectively "Plaintiffs") filed a complaint in the United States District Court for the Northern District of California. Plaintiffs alleged that the Environmental Protection Agency (EPA or the Agency) failed to perform certain non- discretionary duties in accordance with the Act to promulgate final actions for two nonattainment areas under the 2010 1-hour primary sulfur dioxide (SO<INF>2</INF>) national ambient air quality standard (NAAQS): A final federal implementation plan (FIP) for the Detroit, Michigan SO<INF>2</INF> nonattainment area, and approval or disapproval of the state implementation plan (SIP) for the Baltimore and Anne Arundel Counties, Maryland SO<INF>2</INF> nonattainment area. The proposed consent decree would establish deadlines for EPA to take these actions.
