Searchable List of Filers

The Source Registration and Greenhouse Gas facility search tool lists the facilities that must submit Source Registration (SR) and/or Greenhouse Gas (GHG) reports to MassDEP and their next due dates.  Data in this tool is refreshed nightly.  

Instructions – click column headings to sort; click on a facility to display the address information; ctrl-click to select multiple facilities.  If you need the entire list, please download the spreadsheet: SR & GHG Filers List (updated March 6, 2026).

Limitations – This list and the due dates are based on existing MassDEP records.  Facilities are responsible for assessing their own requirements to submit reports based on their current equipment and emissions and the SR and GHG regulations.  Criteria for SR/GHG reporting are found in Air Pollution Control Regulations 310 CMR 7.12 (SR) and 310 CMR 7.71 (GHG).  See the SR/GHG Program webpage for details.

Contact MassDEP” – Where this appears in a record, the facility should contact MassDEP at baw.edep@mass.gov before starting a new report in eDEP.
