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 electronic 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 Report or Notification of Compliance Status (NOCS) are reports typically submitted by a regulated facility that notifies the designated authority that the facility has achieved compliance with an applicable regulation. (Note: In CEDRI most Notification Reports will be uploaded in PDF form.)
  • 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). These reports will be identified by the report names found in each specific rule.

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 provides three different roles for reporting facilities, a role for regional/state/local/tribal regulatory agencies, and a role for EPA personnel. These roles are defined below.

  1. Reporting Facilities
    CEDRI allows individual users reporting for facilities to set up their accounts with different roles. These separate roles allow multiple users within or outside a facility to work on a given report. However, only certain verified employees of the facility are eligible to sign and submit reports. These roles are described below:

    1. Preparer: The Preparer is the person responsible for the preparation of reports for signature. Contractors are permitted to register as a Preparer and may assemble submission packages, such as files generated by the Emissions Reporting Tool (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/facility 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 signing and submission authority. Contractors are prohibited from registering as a Certifier.
    3. Delegated Certifier: The Delegated Certifier is a person granted authority by a registered Certifier to sign and submit packages on behalf of the Certifier. The Delegated Certifier is authorized to modify the package a Preparer has assembled, and sign and submit the package to CDX. The Delegated Certifier may perform all the tasks the Preparer may perform, but also has signing and submission authority. Contractors are prohibited from being appointed as a Delegated Certifier.

  2. EPA Region/State/Local/Tribal Agencies
    CEDRI has one role that is used by EPA regional, state, local, and tribal agency users, the State Reviewer role. This role is described below:

    1. State Reviewer: The State Reviewer role encompasses regulatory officials who service local, state, tribal, and/or EPA regional areas. State Reviewers are authorized to review all submissions that are applicable to the states and/or territories for which they are registered. The State Reviewer role should be requested outside of the CEDRI application by contacting EPA via email: CEDRI@epa.gov. The email should include the following information: First and Last Name, Phone number, Organization Information (name, address, and phone number), and email address.
      Note: For convenience purposes, CEDRI has labeled this function as State Reviewer.

After Certifiers finalize the reports and submit them to 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. Following a processing period, copies of the reports are also subsequently sent to WebFIRE where the reports are available for public access.

User's Guide and Compliance Report Form Upload Templates

EPA has prepared a comprehensive user's guide to help users with Preparer, Certifier, or Delegated Certifier role register for CDX and CEDRI as well as to help users set up organization profiles for their facilities. EPA has also prepared a separate User's Guide for Users with the State Reviewer roles. This User's Guide can be accessed when you log into CDX/CEDRI. Users may also use the XML Reporting Instructions for details on how to create XML documents to automatically fill out data for a new for Air Emission Compliance Reports form for applicable subparts.

Below are XML schemas (XSDs) and Excel files that can be used as templates to upload information into Compliance Report forms in the CEDRI application. Use the XSDs to prepare an XML file to create a completely or partially filled out Compliance Report form. Use the Excel files to upload data into tables within an existing Compliance Report form. Refer to Appendix B of the user's guide for definitions of data elements contained in the Excel templates. Please note that you do not need to use an XML file or Excel file to enter data into a Compliance Report form, but they may assist in expediting data entry into the form.

Use the dropdown below to select which part/subpart you would like to download Excel upload templates and/or XML upload schema for.
