Current through Register Vol. 46, No. 28, July 10, 2024
(a) In instances
					 where air contaminants from two or more process emission sources may be
					 simultaneously emitted to the outdoor atmosphere through a single emission
					 point, the permissible emission rate or degree of air cleaning required is
					 determined by using the sum of the process weights or emission rate potentials
					 for all process emission sources.
(b) In instances where air contaminants from
					 a single process emission source are emitted to the outdoor atmosphere through
					 more than one emission point, the sum of the emissions from all such emission
					 points shall not exceed the quantity that would be authorized through a single
					 emission point.
(c) In instances
					 where air contaminants from two or more process emission sources are emitted to
					 the outdoor atmosphere through a single emission point and the applicable
					 emission standard for one or more process emission sources, if vented
					 separately to the outdoor atmosphere, is a concentration standard (grains per
					 standard cubic foot), the permissible emission rate through such emission point
					 shall not exceed the quantity that would be authorized if the emissions were
					 through separate emission points.
(d) In instances where a facility owner or
					 operator can demonstrate to the satisfaction of the department that the
					 facility owner or operator will apply BACT for criteria air contaminants or
					 T-BACT for non-criteria air contaminants, the department may specify a less
					 restrictive permissible emission rate or degree of air cleaning for the process
					 emission source or emission point than required under Subpart 212-2 of this
					 Part.
(e)
(1) A process emission source subject to a
					 Federal NSPS under  40 CFR Part 60  (see Table 1, Section
					 200.9  of this
					 Title) satisfies the requirements of this Part for the respective air
					 contaminant regulated by the Federal standard if the facility owner or operator
					 can demonstrate that the facility is in compliance with the relevant Federal
					 regulation.
(2) A process emission
					 source subject to the Federal National Emission Standards for Hazardous Air
					 Pollutants (NESHAP) under  40 CFR Part 61  or Part 63 (see Table 1 of Section
					 200.9  of this
					 Title) satisfies the requirements of this Part for the respective air
					 contaminant regulated by the Federal standard if the facility owner or operator
					 can demonstrate that the process emission source is in compliance with the
					 relevant Federal regulation and, for those NESHAPs regulating HTACs found in
					 Section
					 212-2.2,
					 Table 2 - High Toxicity Air Contaminant List, of this Part, provide a TIA
					 demonstrating that the maximum offsite ambient air concentration is less than
					 the AGC/SGC or meeting the mass emission limit identified in Section
					 212-2.2,
					 Table 2. Either compliance option must have actual emissions less than the PB
					 trigger for the respective air contaminant.
Facility owners or operators required to submit a TIA
						shall submit a protocol describing the procedures to be used to predict the
						maximum offsite ambient air concentration. Once the protocol is approved by the
						department and the TIA is conducted, the facility owner or operator shall
						submit a final report to the department along with the air dispersion modeling
						results for approval. The department requires the use of an EPA approved air
						dispersion model for all screening a n d /or refined air dispersion modeling
						assessments; however, screen dispersion models do not require an approved
						modeling protocol.
