Compliance Update: ECMPS 2.0 Re-engineering Effort

• The Emissions Collection and Monitoring Plan System (ECMPS) is a desktop application used by the Clean Air Markets Division of the EPA to collect air emissions and related data to comply with the Acid Rain Program, Cross-State Air Pollution Rule (CSAPR), and the Mercury and Air Toxics Standards (MATS).
• The ECMP system has been in place since 2009, and Clean Air Markets Division (CAMD) is undertaking a multistep process to update the CAMD Business System (CBS) suite of applications and websites to increase security and improve the accessibility of reported data to the public. The re-engineered ECMPS is a web-based application being referred to as ECMPS 2.0 that will replace the current desktop ECMPS software. Affected sources will have to make enabling modifications to their facility Data Acquisition and Handling Systems (DAHS) software prior to the submission of first quarter 2024 emissions data.
• Beginning with the first quarter of 2024, Emissions Data Reports (EDR) reports generated by a facility’s DAHS will require the usage of JavaScript Object Notation (JSON) reporting format. Additionally, ECMPS 2.0 will require some reporting format changes to certain QA/ QC tests at coal-fired power plants subject to the MATS rule.

EPA will continue beta testing of ECMPS 2.0 with emission reporters, software vendors, and consultants through 2023 and will provide users additional information on the necessary DAHS changes later this year. In the meantime, facilities should contact their DAHS provider for specific information on their implementation process and timing.
