ECMPS Re-engineering Effort

ECMPS 2.0 beta and CBS beta sites have now reopened for testing

The ECMPS 2.0 beta site and CBS beta site have reopened for testing. Configuration data has been updated and several bug fixes have been released. Users are encouraged to log-in and perform testing and provide feedback to EPA at ecmps-beta@camdsupport.com. Read more at the newsletter here.

The Emissions Collection and Monitoring Plan System (ECMPS) 2.0 is a new web-based reporting tool released in beta form to allow industry users and the public to begin testing and learning the new application.

ECMPS 2.0 will replace the current desktop ECMPS software (also referred to as ECMPS 1.0). The initial ECMPS 2.0 application, released in December of 2021, began with the limited functionality of view (no login required) and edit/evaluate (CDX test login required) of monitoring plan data. Subsequent releases added import and export functionality of monitoring plan data. Additional functionality for the data types is available — QA, certifications, and emissions. Data in the beta is not production data and is only being used for testing purposes.

While we continue working on the reengineering of ECMPS, we want to inform affected sources that we are targeting a release date for ECMPS 2.0 in Q1 2026. We want to ensure that affected users can fully test a production-ready beta and are prepared for the upcoming changes with the new system (including the new CDX log-in process). Please note, the target release date is subject to change should we encounter any delays with reengineering development. We will continue to communicate any changes to the anticipated release date as soon as we are able to and will continue to provide updates regarding the beta (including bug fixes and additional functionality implementation).

Testing ECMPS 2.0 Beta

The ECMPS 2.0 Beta development and testing period will continue through 2025.

Start testing now at the ECMPS 2.0 Beta website.


Instructions

CDX

Once ECMPS 2.0 replaces the desktop ECMPS software, ECMPS 2.0 and the CAMD Business System (CBS) will utilize CDX login services; on September 1, 2023, EPA released a test version of CBS to begin integration and testing of the CDX, CBS, and ECMPS Beta application interactions. For new or existing users that do not have a working CDX test login and password, please do the following: 

  1. Ensure you have a CDX test login and current password. This account is specific to the beta environment and is separate from other CDX accounts used for official submissions to EPA. CDX Test If you are a new user follow the updated CDX Start-Up Guide (pdf) (1.95 MB, September 25, 2024) . It is no longer a requirement to select your real organization when registering.  

  1. Login into the CBS test application using your CDX test account credentials. Review your associated facilities to ensure you are either a Designated Representative, Alternate Designated Representative, or you have been granted preparer or submitter role access to your facilities. The CBS test application is separate from the production version, changes to data in test will not be reflected in the production version.  

  1. Login into the ECMPS Beta application. You should now have access to your facility data and the ability to check out and edit data.  

If you have any questions concerning this process, please contact EPA. 

Reporting Instructions and Schema Files

Updated 12/20/2024: The ECMPS 2.0 monitoring plan, quality assurance, and emissions reporting instructions are now available. Please note, although these reporting instructions may have slight modifications due to future minor changes ahead of launch, they should be considered ready for use for any kind of programming development ahead of the ECMPS 2.0 launch. These reporting instruction documents reflect the changes already made to ECMPS 2.0 schema files that were made available on September 25th, 2024. If you have any questions regarding this documentation or the process, please contact EPA at ecmps-beta@camdsupport.com.

Additionally, at this time, there are no planned changes to the MATS reporting requirements for the initial release of ECMPS 2.0. This means that affected sources can expect to continue reporting MATS data into the new ECMPS 2.0 application when it is released as they have been reporting via ECMPS 1.0. Any major changes to reflect MATS submission requirements into ECMPS 2.0 will be announced at a later date. For specific MATS reporting guidance, please read the MATS related FAQs available here and also reference the newly published ECMPS 2.0 reporting instructions and related schemas.

Please note: sources that currently use the existing ECMPS client tool (also known as ECMPS 1.0) for official reporting should continue to use the official reporting instructions and schemas available on the EPA website here. Sources that use ECMPS 1.0 to report MATS related data should additionally refer to any official documentation and instruction provided by OAQPS. The ECMPS 2.0 reporting instructions and related schema should not yet be used for official reporting.
