Current through Register Vol. 48, No. 28, July 12, 2024
a)
				Any owner or operator of a coating line subject to Section
				219.204,
				except coating lines subject to Section
				219.204(q)(6),
				may comply with this Section, rather than with Section 219.204, if a capture
				system and control device are operated at all times the coating line is in
				operation and the owner or operator demonstrates compliance with subsection
				(c), (d), (e), (f), (g), (h), (i), (j), (k), (l), (m), or (n) (depending upon
				the source category) through the applicable coating analysis and capture system
				and control device efficiency test methods and procedures specified in Section
				219.105
				and the recordkeeping and reporting requirements specified in Section
				219.211(e);
				and the control device is equipped with the applicable monitoring equipment
				specified in Section
				219.105(d)
				and the monitoring equipment is installed, calibrated, operated and maintained
				according to vendor specifications at all times the control device is in use. A
				capture system and control device, which does not demonstrate compliance with
				subsection (c), (d), (e), (f), (g), (h), (i), (j), (k), (l), (m), or (n) may be
				used as an alternative to compliance with Section
				219.204 only
				if the alternative is approved by the Agency and approved by the USEPA as a SIP
				revision.
b) Alternative Add-On
				Control Methodologies
1) The coating line is
				equipped with a capture system and control device that provides 81 percent
				reduction in the overall emissions of VOM from the coating line and the control
				device has a 90 percent efficiency; or
2) The system used to control VOM from the
				coating line is demonstrated to have an overall efficiency sufficient to limit
				VOM emissions to no more than what is allowed under Section 219.204. Use of any
				control system other than an afterburner, carbon adsorption, condensation, or
				absorption scrubber system can be allowed only if approved by the Agency and
				approved by the USEPA as a SIP revision. The use of transfer efficiency credits
				can be allowed only if approved by the Agency and approved by the USEPA as a
				SIP revision. Baseline transfer efficiencies and transfer efficiency test
				methods must be approved by the Agency and the USEPA. Such overall efficiency
				is to be determined as follows:
A) Obtain the
				emission limitation from the appropriate subsection in Section
				219.204;
B) Unless complying with
				an emission limitation in Section
				219.204 that
				is already expressed in terms of weight of VOM per volume of solids, calculate
				"S" according to the equation in Section
				219.206.
				For coating lines subject to an emission limitation in Section
				219.204 that
				is already expressed in terms of weight of VOM per volume of solids, "S" is
				equal to such emission limitation;
C) Calculate the overall efficiency required
				according to Section
				219.105(e).
				For the purposes of calculating this value, according to the equation in
				Section
				219.105(e)(2),
				VOM1 is equal to the value of "S" as determined in
				subsection (b)(2)(B). If the coating line is subject to an emission limitation
				in Section
				219.204 that
				is already expressed in terms of weight of VOM per volume of solids,
				VOM1 is equal to that emission limitation.
