Current through Register Vol. 48, No. 38, September 20, 2024
a) The owner or
operator of a source must, for each emission unit at the source that is
addressed in Section 214.603, demonstrate compliance with the applicable
emission limitations in Section 214.603 via the monitoring and testing
requirements set forth in this Section.
b) The owners or operators of the following
sources must, for each emission unit at the source that is addressed in Section
214.603, install, calibrate, maintain, and operate a continuous emissions
monitoring system for the measurement of SO2 emissions
in accordance with 40 CFR 75 (except
40 CFR
75.31 through 34), incorporated by reference
in Section
214.104,
and subsection (d), or utilize an alternative monitoring method available to
the emission unit under 40 CFR 75:
1)
Illinois Power Resources Generating E.D. Edwards;
2) Midwest Generation Joliet;
3) Midwest Generation Powerton; and
4) Midwest Generation Will County.
c) The owner or operator of all
sources not addressed in subsection (b) must, for each emission unit at the
source that is addressed in Section 214.603, either conduct performance testing
in accordance with subsection (e) or install, calibrate, maintain, and operate
a continuous emissions monitoring system for the measurement of
SO2 emissions in accordance with 40 CFR 60 or 40 CFR 75
(except
40 CFR
75.31 through 34), incorporated by reference
in Section 214.104, and subsection (d) of this Section.
d) The owner or operator of a source with an
emission unit demonstrating compliance through the use of a continuous
emissions monitoring system must comply with the following for each unit:
1) If two or more of the emission units
addressed in Section 214.603 are served by a common stack, the owner or
operator may utilize a single continuous emissions monitoring system for those
units;
2) If the owner or operator
of an emission unit subject to Section 214.604(c) changes the method of
demonstrating compliance for that unit from performance testing to use of a
continuous emissions monitoring system, the owner or operator must install,
calibrate, and begin operating the continuous emissions monitoring system on or
before the performance testing deadline determined in accordance with
subsection (e)(2); and
3) The
provisions in
40 CFR
75.31 through 34 regarding missing data
substitution must not be used for purposes of demonstrating compliance with the
requirements set forth in this Subpart.
e) The owner or operator of a source with an
emission unit demonstrating compliance through performance testing must comply
with the following for each unit. All testing done pursuant to this Section
must be conducted at the owner's or operator's own expense:
1) Conduct an initial performance test after
January 1, 2015 and prior to January 1, 2017. If the owner or operator of an
emission unit subject to Section 214.604(c) changes the method of demonstrating
compliance for that unit from use of a continuous emissions monitoring system
to performance testing, the owner or operator must demonstrate compliance by
conducting an initial performance test prior to discontinuing the continuous
emissions monitoring system;
2)
Conduct subsequent performance tests at least once every 5 years from the date
of the last performance test. The date of the initial performance test
conducted pursuant to subsection (e)(1) begins the 5-year period;
3) Conduct additional performance testing
when, in the opinion of the Agency or USEPA, that testing is necessary to
demonstrate compliance with the requirements in Section 214.603. The test must
be conducted within 90 days after receipt of a notice to test from the Agency
or USEPA, unless the notice specifies an alternative testing
deadline;
4) Submit a testing
protocol as described in USEPA's Emission Measurement Center Guideline Document
(GD-042), incorporated by reference in Section 214.104, to the Agency at least
45 days prior to a scheduled emissions test, unless that deadline is waived in
writing by the Agency;
5) Submit a
written notification of a scheduled emissions test to the Agency at least 30
days prior to the test date and again 5 days prior to testing, unless those
deadlines are waived in writing by the Agency. If, after the 30 days' notice of
a test is sent, there is a delay in conducting the test as scheduled (e.g., due
to operational problems), the owner or operator must notify the Agency as soon
as practicable of the delay, either by providing at least 7 days' notice of the
rescheduled test date or by arranging a new test date with the Agency by mutual
agreement;
6) Conduct each
performance test using Method 1, 2, 3, 4, 6, 6A, 6B, 6C, or 19, incorporated by
reference in Section 214.104, or other alternative USEPA methods approved by
the Agency. Each test must consist of at least 3 separate runs, each lasting a
minimum of 60 minutes, and must be conducted during conditions representative
of maximum SO2 emissions. Compliance with the applicable
limitation in Section 214.603 must be determined in accordance with 35 Ill.
Adm. Code 283;
7) If the unit has
combusted more than one type of fuel in the prior year, a separate performance
test is required for each fuel; and
8) Subsequent to each performance test used
to demonstrate compliance, continue operating the emission unit within the
parameters enumerated in the testing results submitted to the Agency for each
test, and monitor the parameters regularly to ensure ongoing
compliance.
