Current through Register Vol. 48, No. 38, September 20, 2024
a) Upon reasonable
request by the Agency, the owner or operator of any volatile organic material
emission source subject to this Subpart or exempted from this Subpart by
provisions of Section
215.480(a), (b) or
(c) shall, at his own expense, demonstrate
compliance to the Agency by methods or procedures listed in Section
215.487(c);
and
b) A person planning to conduct
a volatile organic material emissions test to demonstrate compliance with or
determine applicability of provisions of this Subpart shall notify the Agency
of that intent to test not less than 30 calendar days prior to the planned
initiation of the test.
c) Test
procedures to determine compliance with and applicability of this Subpart are
in 40 CFR Part 60, Appendix A, incorporated by reference at Section
215.105,
and shall be used as delineated below:
1)40
CFR 60, Appendix A, Methods 18, 25 or 25A, as appropriate to the conditions at
the site, shall be used to determine VOM concentration. Method selection shall
be based on consideration of the diversity of organic species present and their
total concentration and on consideration of the potential presence of
interfering gases. Except as indicated in subsections (c)(1)(A) and (c)(1)(B),
the test shall consist of three separate runs, each lasting a minimum of 60
minutes, unless the Agency determines that process variables dictate shorter
sampling times.
A) When the method is to be
used to determine the efficiency of a fixed-bed carbon adsorption system with a
common exhaust stack for all the individual adsorber vessels, the test shall
consist of three separate runs, each coinciding with one or more complete
sequences through the adsorption cycles of all the individual adsorber
vessels.
B) When the method is to
be used to determine the efficiency of a fixed-bed carbon adsorption system
with individual exhaust stacks for each adsorber vessel, each adsorber vessel
shall be tested individually. The test for each adsorber vessel shall consist
of three separate runs. Each run shall coincide with one or more complete
adsorption cycles.
2) 40
CFR Part 60, Appendix A, Method 1 or 1A shall be used for sample and velocity
traverses.
3) 40 CFR Part 60,
Appendix A, Method 2, 2A, 2C or 2D shall be used for velocity and volumetric
flow rates.
4) 40 CFR Part 60,
Appendix A, Method 3 shall be used for gas analysis.
5) 40 CFR Part 60, Appendix A, Method 4 shall
be used for stack gas moisture.
6)
40 CFR Part 60, Appendix A, Methods 2, 2A, 2C, 2D, 3 and 4 shall be performed,
as applicable, at least twice during each test run.
d) This section shall not affect the
authority of the U.S. Environmental Protection Agency under Section 114 of the
Clean Air Act.
