Source Registration (SR) and Greenhouse Gas (GHG) Emissions Reporting Updates

September 5, 2018

The Massachusetts Department of Environmental Protection (MassDEP) has provided recent updates regarding Source Registration (SR) reporting—including those for Greenhouse Gas (GHG) emissions—and web forms.

At this time, the MassDEP has made new SR and GHG web forms available for the 2016 time period. Due to delays in web form availability, MassDEP is accepting SR-only, GHG-only, or combined SR/GHG emissions reports only for 2016, not for 2017.

All necessary reports are to be submitted to the MassDEP by the date specified for your facility, the details of which will be mailed to you, including: your reporting deadline, facility identifiers, and the reports your facility is required to file.

What Report(s) are You Required to File

The reports that your facility will be required to fill out are determined by well-established regulatory criteria and operating parameters, which include the following distinctions:


Source Registration (SR)

Facilities required to submit SR files are those that:

  • Have potential emissions or heat input capacities above thresholds specified at 310 CMR 7.00: Air Pollution Control
  • Fall within certain categories (e.g. most incinerators), or
  • MassDEP directs to file even if they do not meet regulatory criteria.


Greenhouse Gas Emissions:

  • Are regulated under Title V of the federal Clean Air Act and Appendix C of 310 CMR 7.00: Air Pollution Control, or
  • Emit more than 5,000 tons per year of Carbon Dioxide Equivalent (CO2e).


Any facilities that fall under both criteria will likely be required to file both a SR and GHG report.

How to File Your SR/GHG Reports

Facilities will be required to use the eDEP Online Filing system to submit their SR annual or triennial report and/or their GHG annual report. If you or your facility are new to the MassDEP site and the eDEP, you are required to create an account prior to filing all of your necessary reports.
