Current through Register Vol. 48, No. 38, September 20, 2024
a) Testing to demonstrate compliance with the
requirements of Section
219.413
of this Subpart shall be conducted by the owner or operator by January 1, 2012,
unless such testing has been conducted within the two years immediately
preceding January 1, 2012. Thereafter, testing shall be conducted by the owner
or operator within 90 days after a request by the Agency, or as otherwise
specified in this Subpart. Such 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 such testing to allow the Agency to be
present during such testing.
b) The
methods and procedures of Section
219.105(d) and
(f) shall be used for testing to demonstrate
compliance with the requirements of Section
219.413(a)(1)(B)
or (b)(1) 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
219.112
of this Part. The sampling sites for determining efficiency in reducing VOM
from the dryer exhaust shall be located between the dryer exhaust and the
control device inlet, and between the outlet of the control device and the
exhaust to the atmosphere;
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
219.112
of this Part;
3) To determine the
VOM concentration of the exhaust stream entering and exiting the control
device, Method 25 or 25A, as appropriate, 40 CFR 60, appendix A, incorporated
by reference in Section
219.112
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 control device is less than 50 ppmv, as carbon;
B) The VOM concentration at the inlet of the
control device and the required level of control result in exhaust
concentrations of VOM of 50 ppmv, or less, as carbon; and
C) Due to the high efficiency of the control
device, the anticipated VOM concentration at the control device 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 Method 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;
4)
Notwithstanding the criteria or requirements in Method 25 which specifies a
minimum probe temperature of 129°C (265oF), the
probe must be heated to at least the gas stream temperature of the dryer
exhaust, typically close to 176.7oC
(350oF);
5) During testing, the printing lines shall
be operated at representative operating conditions and flow rates;
and
6) During testing, an air flow
direction indicating device, such as a smoke stick, shall be used to
demonstrate 100 percent emissions capture efficiency for the dryer in
accordance with Section
219.413(a)(1)(A)
of this Subpart.
c) Testing to demonstrate compliance with the
VOM content limitations in Section
219.413(a)(2)(A)
of this Subpart, and to determine the VOM
content of cleaning solvents, cleaning solutions, and inks (pursuant to the
requirements of Section
219.417(b)(1)(B)
of this Subpart), shall be conducted upon
request of the Agency, or as otherwise specified in this Subpart, as follows:
1) The applicable test methods and procedures
specified in Section
219.105(a)
of this Part shall be used; provided, however, Method 24, incorporated by
reference in Section
219.112
of this Part, shall be used to demonstrate compliance; or
2) The manufacturer's specifications for VOM
content for cleaning solvents and inks may be used if such manufacturer's
specifications are based on results of tests of the VOM content conducted in
accordance with methods specified in Section
219.105(a)
of this Part; provided, however, Method 24 shall be used to determine
compliance.
d) Testing
to demonstrate compliance with the requirements of Section
219.413(b)
of this Subpart shall be conducted as set forth in the owner or operator's plan
approved by the Agency and USEPA as federally enforceable permit conditions
pursuant to Section
219.413(b)
of this Subpart.
e) Testing to
determine the VOM composite partial vapor pressure of cleaning solvents,
cleaning solvent concentrates, and as-used cleaning solutions shall be
conducted in accordance with the applicable methods and procedures specified in
Section
219.110
of this Part.
