## Text

Section 202
Section 202.212  Analysis of
Environmental Quality
a)         A permit application under this Subpart shall provide a
comparison of the ambient air quality under existing requirements and the
ambient air quality which would exist under the proposed ACS.  This analysis
shall include dispersion modeling based on the best and most appropriate models
for the pollutant and emission sources involved, unless the Agency finds that:
1)         Due to the characteristics of the pollutant and emission
source, dispersion modeling is inappropriate or unnecessary for determining
effects on air quality; or
2)         The location of emission sources included in the ACS are not
more than 250 meters apart, the effective plume height of the emission
increases and decreases are not significantly different and the differences in
the characteristics of the emission sources are not likely to affect ambient
air quality; or
3)         Differences in location, plume height, operating practice, and
other characteristics of the emission sources subject to the ACS are not likely
to significantly affect ambient air quality. An effect on ambient air quality
is significant if it equals or exceeds the levels specified in the following
table:

b)         The applicant shall analyze the air quality impacts resulting
from trades between emission sources, including the impact of emissions which
differ in their qualitative impact on health or the environment.
c)         The analysis shall describe any other impacts on the
environment which may accompany the proposed ACS.
