EPA's Clean Air Markets Division (CAMD) collects detailed emissions data and other operating
information from power plants across the country under the Acid Rain Program (ARP), the
Cross-State Air Pollution Rule (CSAPR), the CSAPR update, and the Mercury and Air Toxics
Standards (MATS). CAMD updates summary emissions data every quarter and offers
interactive tools to provide the public with access to high quality, relevant information.
