The Clean Air Act (CAA) authorizes EPA to regulate air pollution from stationary sources like chemical plants, utilities, and steel mills. EPA delegates much of its CAA authority to state, local, and tribal agencies. To help manage the national CAA stationary source compliance monitoring and enforcement program, EPA requires that delegated agencies regularly report data on types of facilities within their jurisdiction and activities conducted, such as compliance evaluations, compliance determinations, and enforcement actions. Dashboards provide an easy-to-use summary of activities to answer questions like: which facilities are regulated, how many have been evaluated, and how many have alleged violations and were subject to enforcement. Charts are based on the Federal Fiscal Year.
