The August 2017 proposed modifications to the MassDEP air regulations have been finalized and the air source registration reporting deadlines have been changed! Going forward for RY2019, the new reporting deadlines are as follows:
- April 1st
- Triennial filers
- May 1st
- Facilities that are subject to 310 CMR 7.0: Appendix C in the prior year (Operating Permit)
- June 1st
- Facilities that have a Restricted Emissions Status (RES)
- Facilities that had ACTUAL emissions of lead equal to or greater than 0.5 tons, or ACTUAL emissions of NOx or VOC equal to or greater than 25.0 tons in the previous year
In addition, MassDEP has changed the fuel utilization thresholds. A facility will now be required to file a source registration if its facility-wide maximum energy input from all fuels is equal to or greater than 40 MMBTU/hr. In addition, if the facility operates an emission unit that combusts natural gas, propane, butane, or distillate oil with a maximum energy input equal to or greater than 10 MMBTU/hr the facility will be required to file a source registration.
Facilities will also be required to file a source registration if their actual emissions in the previous calendar year were equal to or greater than any of the following:
- Lead: 0.5 tons
- NOx: 25.0 tons
- VOC: 25.0 tons
The question remains as to when source registrations will be due this year as the new reporting system and forms are not yet available. Once the system and forms are up, CAPACCIO will be conducting a webinar to walk through the new forms and answer any questions which may arise regarding the reporting deadlines, which are expected to be released at the same time.
