Current through Reg. 49, No. 28; July 12, 2024
(a) In the
					 Beaumont-Port Arthur, Dallas-Fort Worth, El Paso, and
					 Houston-Galveston-Brazoria areas, as defined in §
											115.10 of
					 this title (relating to Definitions), compliance with the control requirements
					 in §
											115.432 of
					 this title (relating to Control Requirements) must be determined by applying
					 the following test methods, as appropriate:
(1) Methods 1 - 4 (40 Code of Federal
					 Regulations (CFR) Part 60, Appendix A) for determining flow rates, as
					 necessary;
(2) Method 24 (40 CFR
					 Part 60, Appendix A) for determining the volatile organic compounds (VOC)
					 content and density of printing inks and related coatings;
(3) Method 25 (40 CFR Part 60, Appendix A)
					 for determining total gaseous nonmethane organic emissions as carbon;
(4) Methods 25A or 25B (40 CFR Part 60,
					 Appendix A) for determining total gaseous organic concentrations using flame
					 ionization or nondispersive infrared analysis;
(5) the United States Environmental
					 Protection Agency (EPA) guidelines series document "Procedures for Certifying
					 Quantity of Volatile Organic Compounds Emitted by Paint, Ink, and Other
					 Coatings," EPA-450/3-84-019, as in effect December 1984;
(6) additional performance test procedures
					 described in
					 40 CFR
					 §60.444 (as amended through October 18,
					 1983 (48 FR 48375));
(7) minor
					 modifications to these methods and procedures approved by the executive
					 director; and
(8) for the capture
					 efficiency, the applicable procedures outlined in
					 40
					 CFR §52.741, Subpart O, Appendix B (as
					 amended through October 21, 1996 (61 FR 54559)). These procedures are:
					 Procedure T - Criteria for and Verification of a Permanent or Temporary Total
					 Enclosure; Procedure L - VOC Input; Procedure G.2 - Captured VOC Emissions
					 (Dilution Technique); Procedure F.1 - Fugitive VOC Emissions from Temporary
					 Enclosures; Procedure F.2 - Fugitive VOC Emissions from Building Enclosures.
(A) The following exemptions apply to capture
					 efficiency testing requirements.
(i) If a
					 source installs a permanent total enclosure that meets the specifications of
					 Procedure T and that directs all VOC to a control device, then the capture
					 efficiency is assumed to be 100%, and the source is exempt from capture
					 efficiency testing requirements. This does not exempt the source from
					 performance of any control device efficiency testing that may be required. In
					 addition, a source must demonstrate all criteria for a permanent total
					 enclosure are met during testing for control efficiency.
(ii) If a source uses a control device
					 designed to collect and recover VOC (e.g., carbon adsorption system), an
					 explicit measurement of capture efficiency is not necessary if the following
					 conditions are met. The overall control of the system can be determined by
					 directly comparing the input liquid VOC to the recovered liquid VOC. The
					 general procedure for use in this situation is given in
					 40 CFR
					 §60.433 (as amended through October 17,
					 2000 (65 FR 61761)) with the following additional restrictions.
(I) The source must be able to equate solvent
					 usage with solvent recovery on a 24-hour (daily) basis, rather than a 30-day
					 weighted average. This verification must be done within 72 hours following each
					 24-hour period of the 30-day period specified in
					 40 CFR
					 §60.433 (as amended through October 17,
					 2000 (65 FR 61761)).
(II) The
					 solvent recovery system (i.e., capture and control system) must be dedicated to
					 a single process line (e.g., one process line venting to a carbon adsorption
					 system); or if the solvent recovery system controls multiple process lines, the
					 source must be able to demonstrate that the overall control (i.e., the total
					 recovered solvent VOC divided by the sum of liquid VOC input to all process
					 lines venting to the control system) meets or exceeds the most stringent
					 standard applicable for any process line venting to the control
					 system.
(B)
					 The capture efficiency must be calculated using one of the following four
					 protocols referenced. The owner or operator of any affected source shall use
					 one of these protocols, unless a suitable alternative protocol is approved by
					 the executive director and the EPA.
(i)
					 Gas/gas method using temporary total enclosure (TTE). The EPA specifications to
					 determine whether a temporary enclosure is considered a TTE are given in
					 Procedure T. The following equation must be used to determine the capture
					 efficiency for this protocol.

(ii)
					 Liquid/gas method using TTE. The EPA specifications to determine whether a
					 temporary enclosure is considered a TTE are given in Procedure T. The following
					 equation must be used to determine the capture efficiency for this protocol.

(iii)
					 Gas/gas method using the building or room enclosure (BE) in which the affected
					 source is located and in which the mass of VOC captured and delivered to a
					 control device and the mass of fugitive VOC that escapes from building
					 enclosure are measured while operating only the affected facility. All fans and
					 blowers in the BE must be operating as they would under normal production. The
					 following equation must be used to determine the capture efficiency for this
					 protocol.

(iv)
					 Liquid/gas method using a BE in which the mass of liquid VOC input to process
					 and the mass of fugitive VOC that escapes from BE are measured while operating
					 only the affected facility. All fans and blowers in the BE must be operated as
					 they would under normal production. The following equation must be used to
					 determine the capture efficiency for this protocol.

(C) The operating parameters selected for
					 monitoring of the capture system for compliance with the requirements in §
													115.436(a)
					 of this title (relating to Monitoring and Recordkeeping Requirements) must be
					 monitored and recorded during the initial capture efficiency testing and
					 thereafter during facility operation. The executive director may require a new
					 capture efficiency test if the operating parameter values change significantly
					 from those recorded during the initial capture efficiency test.
