Environmental Integrity Project v. EPA

The federal district court for the District of Columbia concluded that it lacked subject matter jurisdiction over an action that sought to compel EPA to respond to a 2011 petition asking the agency to identify ammonia as a criteria pollutant. The plaintiffs had alleged that ammonia contributes to regional haze, which has been associated with climate impacts. The court ruled that it did not have jurisdiction because the plaintiffs had failed to comply with the notice requirement of the Clean Air Act citizen suit provision and could not use the Administrative Procedure Act to circumvent the notice requirement.
