Current through Register Vol. 49, No. 13, September 23, 2024
Subpart
1.
Applicability.
For the purpose of using the methods referenced in part
7017.2050, the requirements in
this part apply unless otherwise stated in the applicable requirement or
compliance document.
Subp.
2.
Sample port location.
The sampling location, as selected by Method 1, is the same
for each pollutant during a performance test.
Subp. 3.
Particulate matter
determination.
The owner or operator must conduct particulate matter
emission tests as required in this subpart.
A. Unless the commissioner has approved an
equivalent method, the owner or operator must use Method 5, Code of Federal
Regulations, title 40, part 60, Appendix A-3, as amended, and Method 202, Code
of Federal Regulations, title 40, part 51, Appendix M, as amended.
B. The owner or operator must report:
(1) the results for filterable, organic
condensable, and inorganic condensable particulate matter separately;
and
(2) the sum of filterable and
organic condensable particulate matter.
C. An emission facility's compliance status
is based on a comparison of the sum of filterable and organic condensable
particulate matter to the applicable limit, unless otherwise required under
chapter 7011.
D. When submitting a
proposed test plan, an owner or operator may apply to the commissioner to
exclude organic condensable particulate matter from a performance test for
particulate matter. The owner or operator must demonstrate:
(1) through previous performance test results
that the emissions unit is not a source of organic condensable particulate
matter emissions; or
(2) that an
exception in Method 202, section 1.4(h), as amended, applies.
Subp. 4.
PM-10
determination.
The owner or operator must conduct PM-10 emission tests as
required in this subpart.
A. Unless
the commissioner has approved an equivalent method, the owner or operator must
use Method 201 or 201A, Code of Federal Regulations, title 40, part 51,
Appendix M, as amended, and Method 202, Code of Federal Regulations, title 40,
part 51, Appendix M, as amended.
B.
The owner or operator must report:
(1) the
results for filterable, organic condensable, and inorganic condensable PM-10
separately; and
(2) the sum of
filterable, organic condensable, and inorganic condensable PM-10.
C. An emission facility's
compliance status is based on a comparison of the sum of filterable, organic
condensable, and inorganic condensable PM-10 to the applicable PM-10 limit,
unless otherwise required under chapter 7011.
D. When submitting a proposed test plan, an
owner or operator may apply to the commissioner to exclude organic and
inorganic condensable particulate matter from a performance test for PM-10. The
owner or operator must demonstrate:
(1)
through previous performance test results that the emissions unit is not a
source of organic or inorganic condensable particulate matter emissions;
or
(2) that an exception in Method
202, section 1.4(h), as amended, applies.
Subp. 4a.
PM-2.5 determination.
The owner or operator must conduct PM-2.5 emission tests as
required in this subpart.
A. Unless
the commissioner has approved an equivalent method, the owner or operator must
use Method 201A, Code of Federal Regulations, title 40, part 51, Appendix M, as
amended, and Method 202, Code of Federal Regulations, title 40, part 51,
Appendix M, as amended.
B. The
owner or operator must report:
(1) the
results for filterable, organic condensable, and inorganic condensable PM-2.5
separately; and
(2) the sum of
filterable, organic condensable, and inorganic condensable PM-2.5.
C. An emission facility's
compliance status is based on a comparison of the sum of filterable, organic
condensable, and inorganic condensable to the applicable PM-2.5 limit, unless
otherwise required under chapter 7011.
D. When submitting a proposed test plan, an
owner or operator may apply to the commissioner to exclude organic and
inorganic condensable particulate matter from a performance test for PM-2.5.
The owner or operator must demonstrate:
(1)
through previous performance test results that the emissions unit is not a
source of organic or inorganic condensable particulate matter emissions;
or
(2) that an exception in Method
202, section 1.4(h), as amended, applies.
Subp. 5.
Opacity determination by
Method 9.
Opacity observations must be performed by a certified
observer and in accordance with the requirements of Method 9. In addition, the
requirements of subpart
6 and the following items
apply:
A. The commissioner must reject
the opacity results if the commissioner cannot determine the compliance status
of the emission facility due to error, bias, or insufficient documentation
during the performance test. The recommendations of Method 9 and EPA document
EPA-600/4-77-027b, Addition Section
3.12 (Feb. 1984), as amended,
entitled "Quality Assurance Handbook for Air Pollution Measurement Systems:
Volume III. Stationary Source Specific Methods," which is incorporated by
reference, must be used in determining the acceptability of opacity results.
This document is available through the Minitex interlibrary loan system and is
not subject to frequent change.
B.
One series of readings is required for each condition where opacity is required
to be tested. Each test run consists of 240 consecutive readings at 15-second
intervals and must be obtained concurrently with a test run for particulate
matter, where applicable. Copies of the opacity form showing all readings and
required notation must be included in the performance test report.
C. The results of continuous monitoring by
transmissometer that indicate that the opacity at the time visual observations
were made was not in excess of the standard are probative but not conclusive
evidence of the actual opacity of an emission if the owner or operator meets
the burden of proving that the instrument used met, at the time of the alleged
violation, Performance Specification 1, had been properly maintained and, at
the time of the alleged violation, calibrated, and that the resulting data have
not been tampered with in any way. The data is subject to the reduction
processes in subpart 6.
D. Data reduction must be
performed in accordance with Paragraph 2.5 of Method 9 and subpart
6. A one-hour period means
any 60 consecutive minutes and a six-minute period means any set of 24
consecutive 15-second intervals.
Subp. 6.
Opacity data reduction
procedures.
For the purpose of this part, "excursion" means an opacity
higher than the base standard that is allowed for a limited number of minutes
within a time period. Compliance with opacity limits is determined from all
data points collected in an averaging period and according to items A and
B.
A. For opacity standards that allow
excursions based on six-minute periods, an exceedance of the standard occurs
if, having taken the allowable excursion into account, any six-minute average
exceeds the standard. The exceedance is expressed as the value of the highest
six-minute average and the number of nonoverlapping six-minute averages that
exceed the standard within the period of the test run.
B. For opacity standards that do not allow
excursions, an exceedance of the standard occurs if any six-minute average
exceeds the standard. The exceedance is expressed as the value of the highest
six-minute average and the number of nonoverlapping six-minute averages that
exceed the standard within the period of the test run.
Subp. 7.
Polychlorinated
dibenzo-p-dioxins and polychlorinated dibenzofurans determination.
For Method 23, each sample run must be at least three hours
in duration at an average sampling rate of 0.5 dscf/minute or higher. The
minimum sample volume is 90 dscf. Longer test runs may be required by the
commissioner to collect a greater sample volume if low resolution mass
spectroscopy is to be used for analysis of the field samples or as otherwise
required by part 7017.2045,
subpart 6.
