Current through Register Vol. 48, No. 38, September 20, 2024
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.
