EPA regulations codified in 40 CFR Part 52, 59 - 63 require affected sources to perform emissions source tests, conduct continuous emissions monitoring, and submit compliance and emissions reports . EPA is promulgating E-Reporting rules to require affected sources to electronically submit source test results, emissions monitoring data, compliance reports, and emissions reports to EPA. As a result the EPA has developed the Compliance and Emissions Data Reporting Interface (CEDRI) which is located on EPA's Central Data Exchange (CDX). The CDX Web is the application used by EPA programs and various stakeholders to manage environmental data transmitted to EPA in order to meet EPA's reporting requirements.
