Emissions Monitoring and Reporting

CAPD is re-engineering the ECMPS software.

EPA is working to determine a revised target date for the new web-based Emissions Collection and Monitoring Plan System.  We will provide more information in the coming year.

EPA implements programs that require complete and accurate monitoring, reporting, and evaluation of power plant emissions. Learn how we collect and maintain these data.

EPA administers the 40 CFR part 75 emissions monitoring, reporting, and recordkeeping program to collect emissions and operations data from most large power plants that combust fossil fuels. Under part 75, EPA requires continuous measurement and reporting of carbon dioxide (CO2), nitrogen oxides (NOX), and sulfur dioxide (SO2) emissions. EPA also collects mercury and particulate matter data for 40 CFR part 63 Mercury and Air Toxics Standards (MATS) and CO2 for 40 CFR part 60 greenhouse gas performance standards for electricity generating units.

    To report data, power plants use EPA’s Emissions Collection and Monitoring Plan System (ECMPS) software, which conducts thousands of evaluations to ensure high quality data.
