Current through Register Vol. 48, No. 38, September 20, 2024
a) Testing
to demonstrate compliance with the requirements of this Subpart shall be
conducted by the owner or operator by May 1, 2012. Thereafter, testing shall be
conducted within 90 days after a request by the Agency, or as otherwise
provided in this Subpart. The testing shall be conducted at the expense of the
owner or operator and the owner or operator shall notify the Agency in writing
30 days in advance of conducting the testing to allow the Agency to be present
during testing.
b) Testing to
demonstrate compliance with the VOM content limitations in Section
218.901(b)
of this Subpart shall be conducted as follows:
1) Method 24, incorporated by reference in
Section
218.112
of this Part, shall be used for non-reactive adhesives. If it is demonstrated
to the satisfaction of the Agency and the USEPA that plant adhesive formulation
data are equivalent to Method 24 results, formulation data may be used. In the
event of any inconsistency between a Method 24 test and a facility's
formulation data, the Method 24 test will govern;
2) Appendix A of 40 CFR 63, Subpart PPPP,
incorporated by reference in Section
218.112
of this Part, shall be used for reactive adhesives.
3) The manufacturer's specifications for VOM
content for adhesives may be used if the specifications are based on results of
tests of the VOM content conducted in accordance with methods specified in
subsections (b)(1) and (b)(2) of this Section, as applicable.
c) For afterburners and carbon
adsorbers, the methods and procedures of Section
218.105(d) through
(f) of this Part shall be used for testing to
demonstrate compliance with the requirements of Section
218.901(d)
of this Subpart, as follows:
1) To select the
sampling sites, Method 1 or 1A, as appropriate, 40 CFR 60, appendix A,
incorporated by reference in Section
218.112
of this Part;
2) To determine the
volumetric flow rate of the exhaust stream, Method 2, 2A, 2C, or 2D, as
appropriate, 40 CFR 60, appendix A, incorporated by reference in Section
218.112
of this Part;
3) To determine the
VOM concentration of the exhaust stream entering and exiting the emissions
control system, Method 25 or 25A, as appropriate, 40 CFR 60, appendix A,
incorporated by reference in Section
218.112
of this Part. For thermal and catalytic afterburners, Method 25 must be used,
except under the following circumstances, in which case Method 25A must be
used:
A) The allowable outlet concentration
of VOM from the emissions control system is less than 50 ppmv, as
carbon;
B) The VOM concentration at
the inlet of the emissions control system and the required level of control
result in exhaust concentrations of VOM of 50 ppmv, or less, as
carbon;
C) Due to the high
efficiency of the emissions control system, the anticipated VOM concentration
at the emissions control system exhaust is 50 ppmv or less, as carbon,
regardless of inlet concentration. If the source elects to use Method 25A under
this option, the exhaust VOM concentration must be 50 ppmv or less, as carbon,
and the required destruction efficiency must be met for the source to have
demonstrated compliance. If the Method 25A test results show that the required
destruction efficiency apparently has been met, but the exhaust concentration
is above 50 ppmv, as carbon, a retest is required. The retest shall be
conducted using either Method 25 or 25A. If the retest is conducted using
Method 25A and the test results again show that the required destruction
efficiency apparently has been met, but the exhaust concentration is above 50
ppmv, as carbon, the source must retest using Method 25;
D) During testing, the cleaning equipment
shall be operated at representative operating conditions and flow
rates.
d) An
owner or operator using an emissions control system other than an afterburner
or carbon adsorber shall conduct testing to demonstrate compliance with the
requirements of Section
218.901(d)
as set forth in the owner's or operator's plan approved by the Agency and USEPA
pursuant to Section
218.901(d)(3).
