The testing requirements for surface coating processes in the
Beaumont-Port Arthur, Bexar County, Dallas-Fort Worth, El Paso, and
Houston-Galveston-Brazoria areas and in Gregg, Nueces, and Victoria
Counties are as follows.
(1) The owner or operator shall determine compliance
with §115.421 of this title (relating to Emission Specifications)
by applying the following test methods, as appropriate, except as
specified in paragraph (5) of this section. Where a test method also
inadvertently measures compounds that are exempt solvent, an owner
or operator may exclude these exempt solvents when determining compliance
with an emission standard:
(A) Test Method 24 (40 Code of Federal Regulations
(CFR) Part 60, Appendix A) with a one-hour bake;
(B) ASTM International Test Methods D 1186-06.01, D
1200-06.01, D 3794-06.01, D 2832-69, D 1644-75, and D 3960-81;
(C) The United States Environmental Protection Agency
(EPA) guidelines series document "Procedures for Certifying Quantity
of Volatile Organic Compounds (VOC) Emitted by Paint, Ink, and Other
Coatings (EPA-450/3-84-019)," as in effect December, 1984;
(D) additional test procedures described in 40 Code
of Federal Regulations (CFR) §60.446; or
(E) minor modifications to these test methods approved
by the executive director.
(2) Compliance with §115.423(3) of this title
(relating to Alternate Control Requirements) must be determined by
applying the following test methods, as appropriate:
(A) Test Methods 1-4 (40 CFR Part 60, Appendix A) for
determining flow rates, as necessary;
(B) Test Method 25 (40 CFR Part 60, Appendix A) for
determining total gaseous nonmethane organic emissions as carbon;
(C) Test Method 25A or 25B (40 CFR Part 60, Appendix
A) for determining total gaseous organic concentrations using flame
ionization or nondispersive infrared analysis;
(D) additional performance test procedures described
in 40 CFR §60.044; or
(E) minor modifications to these test methods approved
by the executive director.
(3) Compliance with the alternative emission limits
in §115.421(11) of this title must be determined by applying
the following test methods, as appropriate:
(A) Protocol for Determining the Daily VOC Emission
Rate of Automobile and Light-Duty Truck Topcoat Operations (EPA 450/3-88-018);
or
(B) The procedure contained in this paragraph for determining
daily compliance with the alternative emission limitation in §115.421(11)
of this title for final repair. Calculation of occurrence weighted
average for each combination of repair coatings (primer, specific
basecoat, clearcoat) must be determined by the following procedure.
(i) The characteristics identified below, which are
represented in the following equations by the variables shown, are
established for each repair material as sprayed:

(ii) The relative occurrence weighted usage is calculated
as follows:

(iii) The occurrence weighted average (Q) in pounds
of VOC per gallon of coating (minus water and exempt solvents) as
applied for each potential combination of repair coatings is calculated
according to paragraph (4) of this section.

(4) In the Beaumont-Port Arthur, Bexar County, Dallas-Fort
Worth, El Paso, and Houston-Galveston-Brazoria areas, the owner or
operator of surface coating processes subject to §115.423(3)
of this title shall measure the capture efficiency using applicable
procedures outlined in 40 CFR §52.741, Subpart O, Appendix B.
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; and Procedure F.2-Fugitive
VOC Emissions from Building Enclosures.
(A) Exemptions to capture efficiency testing requirements:
(i) If a source installs a permanent total enclosure
(PTE) that meets the specifications of Procedure T and directs all
VOC to a control device, then the capture efficiency is assumed to
be 100%, and the source is exempted 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 PTE 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, 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 must be done within 72 hours following each
24-hour period of the 30-day period.
(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 adsorber 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. Any affected source
must 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 capture efficiency
equation to be used for this protocol is:
Attached Graphic
(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 capture efficiency equation to be used for
this protocol is:
Attached Graphic
(iii) Gas/gas method using the building or room in
which the affected source is located as the enclosure (BE) and in
which G and F 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 capture efficiency equation to be used for
this protocol is:
Attached Graphic
(iv) Liquid/gas method using a BE in which L and F
are measured while operating only the affected facility. All fans
and blowers in the building or room must be operated as they would
under normal production. The capture efficiency equation to be used
for this protocol is:
Attached Graphic
(C) The following conditions must be met in measuring
capture efficiency:
(i) Any error margin associated with a test protocol
may not be incorporated into the results of a capture efficiency test.
(ii) All affected facilities must accomplish the initial
capture efficiency testing by July 31, 1992 in Brazoria, Dallas, El
Paso, Galveston, Harris, Jefferson, Orange, and Tarrant Counties,
and by July 31, 1993 in Chambers, Collin, Denton, Fort Bend, Hardin,
Liberty, Montgomery, and Waller Counties, except that all mirror backing
coating facilities must accomplish the initial capture efficiency
testing by July 31, 1994. Affected sources in the Bexar County area
must conduct initial capture efficiency testing by no later than July
1, 2024.
(iii) During an initial pretest meeting, the executive
director and the source owner or operator shall identify those operating
parameters that must be monitored to ensure that capture efficiency
does not change significantly over time. These parameters must be
monitored and recorded initially during the 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.
(5) The following additional testing requirements apply
to each aerospace vehicle or component coating facility subject to
§115.421(10) of this title.
