Electronic Reporting of Air Emissions

  • Electronic Reporting of Air Emissions

    The system of electronic reporting for stationary sources includes the Electronic Reporting Tool (ERT), Compliance and Emissions Data Reporting Interface (CEDRI) and WebFIRE.

The electronic reporting system is comprised of the ERT, CEDRI and WebFIRE. The ERT is used to electronically create stationary source sampling test plans and reports. CEDRI accepts electronically submitted performance test reports, notification of compliance status (NOCS) reports, periodic reports (such as semi-annual compliance reports) and Information Collection Requests (ICR) required in 40 CFR Part 60, 62 and 63. WebFIRE is an EPA database that stores the reports from CEDRI and EPA's recommended emission factors for criteria and hazardous air pollutants.
