35 Ill. Adm. Code 204.1130
Air Quality Analysis
Section 204.1130 Air Quality Analysis
a) Preapplication
Analysis
1) Any
application for a permit under this Part shall contain an analysis of ambient
air quality in the area that the major stationary source or major modification
would affect for each of the following pollutants:
A) For
the source, each pollutant that it would have the potential to emit in a
significant amount;
B) For
the modification, each pollutant for which it would result in a significant net
emissions increase.
2) With
respect to any such pollutant for which no NAAQS exists, the analysis shall
contain air quality monitoring data the Agency determines is necessary to
assess ambient air quality for that pollutant in any area that the emissions of
that pollutant would affect.
3) With
respect to any such pollutant for which such a NAAQS does exist, the analysis shall
contain continuous air quality monitoring data gathered for purposes of
determining whether emissions of that pollutant would cause or contribute to a
violation of the standard or any maximum allowable increase.
4) In
general, the continuous air quality monitoring data that is required shall have
been gathered over a period of at least one year and shall represent at least
the year preceding receipt of the application. However, if the Agency
determines that a complete and adequate analysis can be accomplished with
monitoring data gathered over a period shorter than one year (but not less than
four months), the data that is required shall have been gathered over at least
that shorter period.
5) The
owner or operator of a proposed stationary source or modification of VOM who
satisfies all conditions of 40 CFR 51, appendix S, section IV, (incorporated by
reference in Section 204.100) may provide post-approval monitoring data for
ozone in lieu of providing preconstruction data as required by this subsection
(a).
b) Postconstruction
Monitoring. The owner or operator of a major stationary source or major
modification shall, after construction of the stationary source or
modification, conduct such ambient monitoring as the Agency determines is
necessary to determine the effect emissions from the stationary source or
modification may have, or are having, on air quality in any area.
c) Operations
of Monitoring Stations. The owner or operator of a major stationary source or
major modification shall meet the requirements of 40 CFR 58, appendix B (incorporated
by reference in Section 204.100), during the operation of monitoring stations
for purposes of satisfying this Section.
