Affected: IC 13-15; IC 13-17
Sec. 11.
(a) The
department may increase a PAL emission limitation during the PAL effective
period only if the major stationary source complies with the following
provisions:
(1) The owner or operator of the
major stationary source shall submit a complete application to request an
increase in the PAL limit for a PAL major modification. The application shall
identify the emissions units contributing to the increase in emissions so as to
cause the major stationary source's emissions to equal or exceed its
PAL.
(2) As part of this
application, the major stationary source owner or operator shall demonstrate
that the sum of the baseline actual emissions of the small emissions units plus
the sum of the baseline actual emissions of the significant and major emissions
units assuming application of BACT equivalent controls plus the sum of the
allowable emissions of the new or modified emissions units exceeds the PAL. The
level of control that would result from BACT equivalent controls on each
significant or major emissions unit shall be determined by conducting a new
BACT analysis at the time the application is submitted unless the emissions
unit is currently required to comply with a BACT or LAER requirement that was
established within the preceding ten (10) years. In this case, the assumed
control level for that emissions unit shall be equal to the level of BACT or
LAER with which that emissions unit must currently comply.
(3) The owner or operator shall obtain a
major NSR permit for all emissions units identified in subdivision (1)
regardless of the magnitude of the emissions increase resulting from them.
These emissions units shall comply with any emissions requirements resulting
from the major NSR process even though they have also become subject to the PAL
or continue to be subject to the PAL.
(4) The PAL permit shall require that the
increased PAL level shall be effective on the day any emissions unit that is
part of the PAL major modification becomes operational and begins to emit the
PAL pollutant.
(b) The
department shall calculate the new PAL as the sum of the allowable emissions
for each modified or new emissions unit plus the sum of the baseline actual
emissions of the significant and major emissions units, assuming application of
BACT equivalent controls as determined in accordance with subsection (a)(2),
plus the sum of the baseline actual emissions of the small emissions
units.
(c) The PAL permit must be
revised to reflect the increased PAL level under the public notice requirements
of section 5 of this rule.
