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, the Revised 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.
