Current through Register Vol. 48, No. 28, July 12, 2024
"Volatile organic material" (VOM) or "volatile organic
				  compound" (VOC) means any compound of carbon, excluding carbon monoxide, carbon
				  dioxide, carbonic acid, metallic carbides or carbonates, and ammonium
				  carbonate, that participates in atmospheric photochemical reactions.
a) This definition of VOM includes any
				organic compound that participates in atmospheric photochemical reactions,
				other than the compounds listed in this subsection (a). USEPA has determined
				that the compounds listed in this subsection (a) have negligible photochemical
				reactivity.

b) For purposes of determining VOM emissions
				and compliance with emissions limits, VOM will be measured by the test methods
				in the approved implementation plan or  40 CFR 60, appendix A, incorporated by
				reference at 35 Ill. Adm. Code 215.105, 218.112, and 219.112, as applicable, or
				by source-specific test methods that have been established under a permit
				issued under a program approved or promulgated under Title V of the Clean Air
				Act; under 35 Ill. Adm. Code 203; or under Section 9.1(d) of the Act. If such a
				method also measures compounds with negligible photochemical reactivity, these
				negligibly reactive compounds may be excluded as VOM if the amount of those
				compounds is accurately quantified and the exclusion is approved by the
				Agency.
c) As a precondition to
				excluding these negligibly-reactive compounds as VOM, or at any time after
				exclusion, the Agency may require an owner or operator to provide monitoring or
				testing methods and results demonstrating, to the satisfaction of the Agency,
				the amount of negligibly reactive compounds in the source's
				emissions.
d) The USEPA will not be
				bound by any State determination as to appropriate methods for testing or
				monitoring negligibly reactive compounds if the determination is not reflected
				in any of the test methods in subsection (b).
