The 2024 Q2 Reporting Period begins on July 1, 2024

Tuesday, June 25, 2024

The first day of the 2024 Q2 reporting period is Monday, July 1, 2024. Sources required to report 2024 Q2 emissions data under the Acid Rain Program (ARP), the Cross-State Air Pollution Rule (CSAPR), the NOx SIP Call (SIPNOX), the Texas SO2 Trading Program (TXSO2), the Regional Greenhouse Gas Initiative (RGGI), and the Mercury and Air Toxic Standards (MATS) rule have until the end of the day on Tuesday, July 30, 2024 to submit their emissions data to the EPA using the ECMPS Client Tool.

During this reporting period, the EPA expects to receive approximately 4,000 emissions data submissions. Sources are encouraged to begin working on their submissions as early as possible in order to give them sufficient time to complete all submissions by the deadline.

Start Early

With the large volume of submissions expected, we encourage sources to start working with their data as soon as possible because, if you have questions you will get a faster response to your technical support request the earlier in the month you submit your request. If you wait until later in the month to begin working with your data and you run into problems that require technical support, your request will be added to a much longer queue of technical support requests.

Technical Support Information

Information on getting technical support through the resources on the Website or by submitting a technical support request has all been consolidated in the Website's Help section. Technical support would like to highlight that, as necessary, FAQs and Known Issues will continue to be updated throughout the submission period. Hours for technical support are listed on the Contact Us page.

Resubmission Requests

Requests to resubmit QA or emissions data should be made using the Resubmission Request Form.
