ECMPS

ECMPS stands for the Emissions Collection and Monitoring Plan System. It is a United States Environmental Protection Agency (EPA) web-based data management system designed to collect, manage, and report emissions data from major sources subject to the Clean Air Act, in particular facilities that use continuous emissions monitoring systems (CEMS).

The system comprises two main components: the Emissions Collection System (ECS) and the Emissions Data System (EDS). ECS collects raw data from CEMS, fuel flow meters, opacity monitors, and related monitoring equipment. EDS stores validated data and provides access for compliance reporting, performance testing, QA/QC records, and EPA program analyses. Data types include CEMS data, fuel analyses, calibration information, and performance test results.

Facilities submit data electronically to ECMPS, where EPA and authorized state agencies perform automated checks and manual reviews. The system supports compliance demonstrations under applicable regulations, including NSPS, MACT, and Title V permits, and is used to generate emission reports, compliance determinations, and, in some cases, public disclosures.

Administration and usage: ECMPS is maintained by the EPA and its regulated community in coordination with state and local agencies. Access to the system is restricted to registered users with appropriate security controls, typically including facility operators, data furnishers, and regulatory staff. The system continues to evolve to improve data quality, traceability, and reporting efficiency in emissions monitoring programs.
