Deadlines for Filing in 2016

MassDEP is spreading out the filing schedule for Source Registration submittals over several months in 2016 as shown below.

We are doing this to improve your experience on eDEP by preventing overload of the system, and to ensure that our SR Help Desk can provide the level of quality support that you need. We also hope that this will make the SR season somewhat easier for those who prepare multiple SRs.

We have published the due dates for each facility under filing schedules above. Each owner/operator of a facility required to file will also be informed of their filing schedule via a letter from MassDEP.

  • April 15 - Operating Permit facilities due
  • May 16 - Non-OP annual filers due (allowing 1 additional month to file beyond the regulatory deadline)
  • June 2 - Deadline for a portion of the facilities filing every 3 years (see List of All Facilities for facility-specific deadlines)
  • July 15 - Deadline for a portion of facilities filing every 3 years (see List of All Facilities for facility-specific deadlines)

NOTE: if you were an Operating Permit facility during any portion of 2015, you will need to file a 2015 Source Registration, even if your classification changed or the facility closed.

EXCEPTIONS: If you are a Non-OP filer AND your MassDEP Permit requires that you file annually, then you must file by May 16 regardless of the information contained in the facility deadline list posted above.. Similarly, if you have received an enforcement document or other communication from MassDEP requiring you to file Source Registration, then you must abide by the provisions of that document, the postings on this web page notwithstanding.

Deferrals for 3-Year Filers

Filings by certain small combustion facilities are deferred until 2017 (reporting for calendar year 2016). Generally these are facilities whose emissions come from combustion units that run on natural gas or #2 oil/diesel and have a maximum input rate of less than 10 MMBtu/hr individually and 40 MMBtu/hr for the entire facility. This does not include facilities with process emission units or incinerators.

If you have any questions, please contact the Source Registration Help Desk. Source Registration Contacts & Help Desk
