nitrogen oxides (NOx) during the ozone season (May 1st through September 30th of each
year). 310 CMR 7.34 establishes a statewide budget of 1,799 tons of NOx mass emissions
from MassNOx Facilities for each ozone season.
(b) Applicability. The units listed in 310 CMR 7.34(7)(b): Table A shall be MassNOx Units
subject to the requirements of 310 CMR 7.34.
(c) Permanently Retired Units. The owner or operator of a MassNOx Unit that is
permanently retired after March 9, 2018 shall comply with the requirements of 310 CMR
7.34(4)(d) and (6)(c) and shall not be subject to the remaining requirements in 310 CMR
7.34.
(d) Averaging Emissions. For the purposes of determining the total ozone season NOx mass
emissions of a MassNOx Facility, the owner or operator of a MassNOx Facility shall not
average the total NOx ozone season mass emissions of a MassNOx Unit with the ozone
season NOx mass emissions of another facility.
(2) Definitions. The terms used in 310 CMR 7.34 are defined at 310 CMR 7.34(2). Where a
term is defined in both 310 CMR 7.00 and 7.34, the definition in 310 CMR 7.34 shall apply.
