Section 096-100-82 - Major modification"Major modification" means:
A. Any modification that would result in a significant emissions increase of any regulated pollutant excluding GHGs at an existing stationary source that emits or has potential to emit significant emissions prior to the modification; andB. Any modification that would result in (1) an increase in the source's potential to emit by significant emissions of any regulated pollutant excluding GHGs from new sources or emission units; or(2) an increase in actual emissions by significant emissions of any regulated pollutant excluding GHGs from the particular physical change or change in the method of operation at an existing stationary source that emits or has potential to emit less than significant emissions prior to the modification.C. A major modification shall not apply to major stationary sources operating in compliance with its PAL license. Instead, for sources with PAL licenses, the definition for PAL major modification shall apply.06- 096 C.M.R. ch. 100, § 82
