Forms for the 2023 reporting year are now available. We also have posted a new list of filers with deadlines. We are sending email notices to responsible officials, facility contacts, and preparers as in previous years.
NEW Controls Reporting: Emission units with a control device will need to include the percent effectiveness for the control. Units with multiple controls will need to provide the control sequences and overall efficiency and effectiveness for all controls combined. See the Tips from the Help Desk or Instructions below for details. Email the SR-GHG Help Desk (email@example.com) with questions or unusual configurations. If you filed for 2021 or 2022, any controls data you entered will prefill in your 2023 forms.
DEADLINES: Filing deadlines for 2024 (for 2023 data) are the deadlines in the current regulations (310 CMR 7.12 and 7.71).
NOTE: The GHG reporting deadlines have been revised to match the Source Registration reporting deadlines. Facilities that are subject to Source Registration will file both Source Registration and GHG reports according to their Source Registration deadline (see 310 CMR 7.71(4)). GHG filers not subject to Source Registration will report by April 16 (due to state holiday on April 15) and annual filers usually due on June 1 will be due on June 3 instead due to the weekend.
CORRECTIONS: If you need to file a correction for a previous year, please contact us first. Corrections need to be filed before starting a new report. Corrections also require filing a full report for all units for the year being corrected to ensure total emission values are correct.
