Current through Register Vol. 48, No. 28, July 12, 2024
a) Following any
				exceedence of the 24-hour ambient air quality standard for PM-10, the Agency
				shall notify the source or sources the Agency has identified as likely to be
				causing or contributing to an exceedence detected by monitoring. Within ninety
				(90) days after receipt of such notification, each source so notified may
				implement Level I or Level II measures, as determined pursuant to subsection
				(d) below.
b) If there is a
				violation of the ambient air quality standard for PM-10 as determined in
				accordance with 40 CFR Part 50, Appendix K, incorporated by reference in
				Section
				212.113
				of this Part, the Agency shall notify the source or sources the Agency has
				identified as likely to be causing or contributing to one or more of the
				exceedences leading to such violation, and such source or sources shall
				implement Level I or Level II measures, as determined pursuant to subsection
				(e) below. The source or sources so identified shall implement such measures
				corresponding to fugitive emissions within ninety (90) days after receipt of
				such notification and shall implement such measures corresponding to any
				nonfugitive emissions according to the approved schedule set forth in such
				source's alternative control plan. Any source identified as causing or
				contributing to a violation of the ambient air quality standard for PM-10 may
				appeal any finding of culpability by the Agency to the Board pursuant to 35
				Ill. Adm. Code 106, Subpart J.
c)
				Upon the finding of a failure to attain by the Administrator of USEPA, the
				Agency shall notify all sources in the applicable area required to submit
				contingency measure plans pursuant to Section
				212.700 of this
				Subpart of such finding by the Administrator; however, the Agency's failure to
				notify a source of its requirement to implement its contingency measure plan
				because of the Administrator's finding of a failure to attain shall not be a
				defense to a violation of this Subpart and shall not relieve the source of its
				obligation to timely comply with this Section. All such sources subject to this
				Subpart shall, within sixty (60) days after receipt of such notification,
				implement any Level II measures corresponding to fugitive emissions subject to
				control under Sections
				212.304,
				212.305,
				212.306,
				212.308,
				212.316(a)
				through (e),
				212.424
				or
				212.464
				and shall implement any Level II measures corresponding to any nonfugitive
				emissions of PM-10 according to the approved schedule set forth in such
				source's alternative control plan, unless such corresponding Level II controls
				have been previously implemented by such source or sources pursuant to
				subsection (a) or (b) above.
d) The
				Agency shall request that sources comply with the Level I or Level II measures
				of their contingency measure plans, pursuant to subsection (a) above, as
				follows:
1) Level I measures shall be
				requested when the magnitude of the monitored exceedence at a given air quality
				monitor is less than or equal to 170
				µg/m3.
2) Level II measures shall be requested when
				the magnitude of the monitored exceedence at a given air quality monitor
				exceeds 170 µg/m3.
