Current through Register Vol. 48, No. 28, July 12, 2024
a)
				Any owner or operator of a coating line subject to Section 218.204 of this
				Subpart, except coating lines subject to Section 218.204(q)(6), may comply with
				this Section, rather than with Section 218.204 of this Subpart, 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 subsections
				(c), (d), (e), (f), (g), (h), (i), (j), (k), (l), (m), or (n) of this Section
				(depending upon the source category) through the applicable coating analysis
				and capture system and control device efficiency test methods and procedures
				specified in Section 218.105 of this Part and the recordkeeping and reporting
				requirements specified in Section 218.211(e) of this Subpart; and the control
				device is equipped with the applicable monitoring equipment specified in
				Section 218.105(d) of this Part 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) of this Section may be used as an alternative
				to compliance with Section 218.204 of this Subpart 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 218.204 of this Subpart. 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 218.204 of this Subpart;
B) Unless complying with an emission
				limitation in Section 218.204 that is already expressed in terms of weight of
				VOM per volume of solids, calculate "S" according to the equation in Section
				218.206 of this Subpart. For coating lines subject to an emission limitation in
				Section 218.204 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 218.105(e) of this Part. For the purposes of calculating
				this value, according to the equation in Section 218.105(e)(2) of this Part,
				VOMl is equal to the value of "S" as determined in
				subsection (b)(2)(B) of this Section. If the coating line is subject to an
				emission limitation in Section 218.204 of this Subpart that is already
				expressed in terms of weight of VOM per volume of solids,
				VOM1 is equal to that emission limitation.
