Fact Sheet

In Massachusetts, a major facility has federal potential or allowable emissions of:

  • 50 tons per year (TPY) or more of Nitrogen Oxides (NOx) or Volatile Organic Compounds (VOC)
  • 10 TPY or more of any one listed Hazardous Air Pollutant (HAP)
  • 25 TPY or more of a combination of HAPs, or
  • 100 TPY other regulated air pollutants

There are many facilities with federal potential emissions greater than these thresholds and operating with very low actual emissions. Examples include: paint spray operations, fleet maintenance sites, school fuel utilization facilities (boilers), small printing operations and job shops.

The "50% or 25% Facility Emission Cap Notification" is a streamlined means to limit a facility's federal potential and actual emissions to either 50% or 25% of all the major facility thresholds. In other words, if your facility has federal potential emissions equal to or greater than a major facility threshold, and you are willing to restrict your facility's actual and federal potential emissions to either 25% or 50% of said threshold by complying with the requirements of 310 CMR 7.02(11) (i.e. facility-wide emissions caps, record keeping and reporting), then complete the notification form and return it to the MassDEP. There is no application fee associated with this notification. Compliance with the facility-wide emission caps defers the applicability of an otherwise applicable major facility requirement such as Operating Permits (310 CMR 7.00: Appendix C), NOx or VOC RACT (310 CMR 7.19, 7.18) or major source MACT to the facility.

This notification process may also be used to establish an emissions cap to lower the facility's Annual Compliance Assurance Fee pursuant to 310 CMR 4.03 Timely Action Schedule & Fee Regulations. To affect a facility's annual compliance assurance fee, this notification form must be submitted to MassDEP before the end of the fiscal year (June 30). Your compliance assurance fee bill is based upon your facility’s status as of July 1 of each year.
