On January 29th, 2026, EPA’s Clean Air and Power Division (CAPD) provided a status update on the ECMPS 2.0 re-engineering effort. The blog post can be found here. Also on February 3, 2026, EPA posted an update on how to prepare for the ECMPS 2.0 production release. That post can be found here.
The countdown to JSON reporting using the new ECMPS 2.0 web-based Client Tool has officially begun!! Q1 2026 is the official start date for ECMPS 2.0 reporting, with reports due no later than April 30, 2026.
A few things we’d like to highlight as you prepare for the upcoming reporting obligation:
- Evaluate the impacts of the migration
- Update data acquisition and handling system (DAHS) to a “JSON capable” release
- Confirm Initial Authorizer (IA) has received and executed the Emissions and Allowance System for Energy (EASEY) program in the Central Data Exchange (CDX)
- Assign necessary agents
- Identify a Low Mass Emission (LME) unit reporting solution
1. Impact from the ECMPS 1.0 -> 2.0 migration
EPA expects the migration to take place on February 13th, at 5:00 PM ET and last approximately 3 weeks. During this time, no reporting software will be available.
A few things to keep in mind:
- For those affected, the 2025-Q4 MATS quarterly compliance report deadline is March 2, 2026. EPA doesn’t expect the ECMPS 2.0 platform to be on-line until March 9that the earliest, facilities MUST get these reports submitted before February 13th! Please keep that in mind when preparing these reports.
- Users will no longer be able to synchronize with the EPA host from the ECMPS 1.0 Client Tool after February 13th. If there is anything you need to load or populate from EPA database, you should plan to do it prior to the migration. While the Client Tool will be functional on your PC, it will no longer be able to connect to any EPA system.
- The Field Audit Checklist Tool (FACT) database will also no longer be supported or populated with new data. Like the ECMPS 1.0 Client Tool, we expect it to remain functional in limited capacity, but it will no longer receive data from ECMPS 1.0. Any future queries should be made through the Clean Air Markets Program Data (CAMPD) website at https://campd.epa.gov/.
- Any resubmissions (MP, QA, or EM) not completed prior to the migration will need to be completed in the web-based ECMPS 2.0 Client Tool using JSON formatted files. Please make sure you have the capability to produce files in this format for any resubmissions going forward.
2. DAHS Readiness
One of the most important considerations, if not the most important, is to confirm that your DAHS can generate a JSON formatted file. Please consult with your DAHS vendor to ensure you are running a release capable of producing these reports.
For VIM Technologies CEMLink6 users, that means running a CEMLink6 v6.2.620.x or greater. If you have identified that you are running a version lower than this, please reach out immediately to our support group at support@vimtechnologies.com for assistance. We do not expect EPA to modify JSON schemas before the Q1 2026 reporting period, but we will continue to monitor things once the migration is complete and the ECMPS 2.0 interface is back on-line.
3. CDX, ORG ID, and EASEY
We’ve scheduled and performed ECMPS 2.0 readiness training for over 200 different companies, over a 3-week timeframe, as part of our ECMPS 2.0 outreach. We hope you were able to attend one of those sessions and truly hope that it was able to give you direction on how to get your IA set up in CDX with the EASEY Program, an ORG ID assigned and be ready for the sponsorship process once EPA gives us the green light. Part 2 of the training series will take place once the migration is complete and will be dedicated to the ECMPS 2.0 user interface.
EPA created a CDX registration guide that will walk the IA through setting up their account in CDX. To get a copy of the guide click here. There is a wealth of information in this guide, and we recommend anyone impacted by ECMPS 2.0 to read it completely.
We are currently in what EPA calls “Phase 1” which is the bulk pre-registration of IAs. If your Designated Representative (DR) has not received the registration emails referenced in the guide, please contact cbs-support@camdsupport.com with the subject line “CDX Initial Registration.” Do not email the CDX Help Desk for initial registration or sponsorship questions. The ONLY way to access EMPCS 2.0 once we go production, is for the DR, or their delegates, to begin the process using the unique link provided in the E-mail.
While some of us have prematurely started on Phase 2, EPA has since requested everyone to hold off until all IAs have been set up properly in the EASEY program with the correct ORG ID. This will prevent any re-work later if ORG IDs need to be cleaned up.
4. Assign Agents
Unfortunately, one area where EPA is not budging on, is regarding Contractor Access. This is a topic we have been very vocal about to both EPA and industry for the last 4 years. This is a feature that’s available in CAMD Business System (CBS) and the current stand-alone ECMPS 1.0 Client Tool and one that the vendors (DAHS vendors, Consultants and Stack testers) rely on to access key information. Without an equivalent feature in ECMPS 2.0, industry will be forced to add a significant number of CDX preparer roles and CBS retrieve agents in the new platforms.
VIM will be sending out under separate E-mail a list of VIM employees who are active users in CDX/CBS that we would request to be added as preparer / retrieve agents. This is required to support your systems going forward. Without this access, we will not be able to troubleshoot or assist in any JSON reporting issues you encounter in the new ECMPS 2.0 web-based tool. If you have a VIM COMPAS contract and rely on VIM to submit your quarterly electronic data reports (EDR), then you will need to assign a Submitter role for your COMPAS contact in CDX and CBS.
5. LME Solution
For LME method sources, ECMPS 2.0 will no longer be capable of producing your JSON formatted quarterly emissions file. This feature is being discontinued by EPA and industry users who currently rely on the ECMPS 1.0 Client Tool to produce these files will need to find an alternative.
In 2023, VIM developed an LME EDR tool for ECMPS 2.0 for the industry to use. It is an advanced web-based utility tool that provides an efficient and cost-effective solution for creating Part 75 LME XML & JSON formatted EDR to import into both ECMPS 1.0 and ECMPS 2.0. If you’d like more information on the tool or would like to take it for a test run, please visit https://lmeedr.com/login or contact our sales group at sales@vimtechnologies.com to set up a live demonstration.
