Abstract |
This report on Clean Air Act (CAA) synthetic minor and minor sources provides summary data on source universe as well as the compliance monitoring activities and enforcement actions by the United States Environmental Protection Agency (EPA), states, tribes and delegated local agencies. This report also includes sources identified as federally-reportable minor sources1 and those sources that have an unknown classification. These sources along with sources classified as synthetic minor sources and minor sources are collectively referred to as non-major sources throughout this report. Synthetic minor sources would be major but have enforceable permit limits to restrict their emissions below major source thresholds. Minor sources, also known as area sources, are facilities that physically cannot emit at or above major source thresholds. The time frame of this report is the 2009 federal fiscal year (FY09), which extends from October 1, 2008, to September 30, 2009. The data provided in this report are from EPAs Air Facility System (AFS). AFS is the national database of record for CAA compliance and enforcement data for stationary sources regulated by EPA, state, tribal and local air pollution agencies. The data was pulled from AFS in March 2010. |
