(a) In the Beaumont-Port Arthur, Bexar County, 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.
Attached Graphic
(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.
Attached Graphic
(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.
Attached Graphic
(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.
(b) In Gregg, Nueces, and Victoria Counties, compliance
with the requirements in this division must be determined by applying
the following test methods, as appropriate:
(1) Methods 1 - 4 (40 CFR Part 60, Appendix A) for
determining flow rates, as necessary;
(2) Method 24 (40 CFR Part 60, Appendix A) for determining
the 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 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)); or
(7) minor modifications to these test methods and procedures
approved by the executive director.
(c) Methods other than those specified in subsections
(a)(1) - (6) and (b)(1) - (6) of this section may be used if approved
by the executive director and validated using Method 301 (40 CFR Part
63, Appendix A). For the purposes of this subsection, substitute "executive
director" each place that Method 301 references "administrator."
