06- 096 C.M.R. ch. 100, § 87 - Minor Modification
"Minor Modification" means a modification pursuant to 06-096 CMR 115 that involves a licensed emission increase of 4 tpy or more for any one regulated pollutant except GHGs, or 8 tpy or more for total regulated pollutants except for GHGs. A modification that is determined not to be a minor revision and:
A. would result in less
than a significant emissions increase of all regulated pollutants excluding
GHGs at an existing stationary source that emits or has potential to emit
significant emissions prior to the modification;
B. would increase the source's potential to
emit by less than significant emissions of all regulated pollutants excluding
GHGs at an existing stationary source that emits or has potential to emit less
than significant emissions prior to the modification; or
C. for a source conducting the
actual-to-projected-actual applicability test for projects involving existing
emission units, if the difference between the projected actual emissions and
the baseline actual emissions for each pollutant from all existing emission
units modified or affected by the project combined with the potential emissions
from the new unit(s) is less than the significant emissions increase for that
pollutant.
