Compliance and Emissions Data Reporting Interface (CEDRI)

CEDRI Overview

EPA regulations codified in 40 CFR Part 60 and 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.

The CEDRI program service supports the submittal of three types of reporting:

  • Performance Test Reports - Performance Test Reports use the Electronic Reporting Tool (ERT), built in Microsoft Access, to generate files containing emissions source test data. Facilities upload these files to CDX using CEDRI.
  • Notification Reports - A Notification of Compliance Status (NCOS) is a report submitted by a regulated facility that notifies the designated authority that the facility has achieved compliance with an applicable regulation.
  • Air Emissions Reports - Air emissions reports are periodic reports submitted to the delegated authority after the facility achieves initial compliance that demonstrate that the facility has maintained continuous compliance with an applicable regulation over the reporting period (e.g., 6 months).

CEDRI supports submission of multiple reports at one time. CEDRI aggregates the uploaded files and completed forms into a single package for submission. The source then certifies and signs the package using the CDX Cross-Media Electronic Reporting Regulation (CROMERR) service.

CEDRI Roles

CEDRI allows users to set up their profiles with different roles. This allows for multiple people within or outside a facility to work on a given report however only allows certain verified employees of the facility to submit and certify reports. The distinction between the two different roles that a user can request is as follows:

  1. Preparer: The Preparer is the person responsible for the preparation of reports for signature and subsequent submission by an authorized representative of the facility. Contractors are permitted to register as a Preparer and may assemble submission packages, such as files generated by the ERT, for the Certifier's approval and signature. A Preparer may not sign and submit a submission package. The Preparer may only access packages which they have prepared.
  2. Certifier: The Certifier is the duly authorized representative of the source or more commonly referred to as the "owner" or "operator" of the facility. The Certifier is authorized to modify the package a Preparer has assembled, and sign and submit the package to CDX. The Certifier may perform all the tasks the Preparer may perform, but also has submission signing authority. Contractors are prohibited from registering as a Certifier.

After certifiers finalize the reports and submit them to the EPA, the reports are stored in the CDX CROMERR archive and are available to certifiers, preparers, and authorized EPA, regional, state, local, and tribal reviewers immediately upon submission. Copies of the reports are also subsequently sent to WebFIRE where the reports are available for public access.
