Facilities with potential emissions or heat input capacities above specific thresholds, or that fall within certain categories, are required to file. MassDEP may also direct others to file even if they do not meet regulatory criteria.
Source Registration reporting provides MassDEP with valuable information on air pollution sources, their emissions, and their effects on ambient air quality across Massachusetts. This information is also used for program planning, technical assistance targeting, state and federal emissions inventories, and state implementation plans (SIPs).
Facilities with potential emissions or heat input capacities above thresholds specified in the regulations are required to file. So, too, are facilities that fall within certain categories. Most incinerators are required to file, for example. MassDEP may also direct a facility to file even if it does not meet any of the regulatory criteria. See 310 CMR 7.00: Air Pollution Control (specifically, 310 CMR 7.12: U Source Registration) for details.
