Universal Citation: 35 IL Admin Code ยง 225.250
Current through Register Vol. 48, No. 38, September 20, 2024
a) The owner or operator of an EGU must comply with the following initial certification and recertification procedures for a CEMS (or an excepted monitoring system pursuant to Section 1.3 of Appendix B to this Part) required by Section 225.240(a)(1). The owner or operator of an EGU that qualifies for, and for which the owner or operator elects to use, the low-mass-emissions excepted methodology pursuant to Section 1.15(b) of Appendix B to this Part, must comply with the procedures set forth in subsection (c) of this Section.
1)
Requirements for Initial Certification. The owner or operator of an EGU must
ensure that, for each CEMS (or excepted monitoring system) required by Section
225.240(a)(1)
(including the automated data acquisition
and handling system), the owner or operator successfully completes all of the
initial certification testing required pursuant to Section 1.4 of Appendix B to
this Part, by the applicable deadline in Section
225.240(b).
In addition, whenever the owner or operator of an EGU installs a monitoring
system to meet the requirements of this Subpart B in a location where no such
monitoring system was previously installed, the owner or operator must
successfully complete the initial certification requirements of Section 1.4 of
Appendix B to this Part.
2)
Requirements for Recertification. Whenever the owner or operator of an EGU
makes a replacement, modification, or change in any certified CEMS, or an
excepted monitoring system pursuant to Section
1.3 of Appendix B to
this Part, and required by Section
225.240(a)(1),
that may significantly affect the ability of the system to accurately measure
or record mercury mass emissions or heat input rate or to meet the
quality-assurance and quality-control requirements of Section
1.5 of Appendix B to this
Part or Exhibit B to Appendix B to this Part, the owner or operator of an EGU
must recertify the monitoring system in accordance with Section 1.4(b) of
Appendix B to this Part. Furthermore, whenever the owner or operator of an EGU
makes a replacement, modification, or change to the flue gas handling system or
the EGU's operation that may significantly change the stack flow or
concentration profile, the owner or operator must recertify each CEMS, and each
excepted monitoring system pursuant to Section
1.3 to Appendix B to
this Part, whose accuracy is potentially affected by the change, all in
accordance with Section 1.4(b) to Appendix B to this Part. Examples of changes
to a CEMS that require recertification include, but are not limited to,
replacement of the analyzer, complete replacement of an existing CEMS, or
change in location or orientation of the sampling probe or site.
3) Approval Process for Initial Certification
and Recertification. Subsections (a)(3)(A) through (a)(3)(D) of this Section
apply to both initial certification and recertification of a CEMS (or an
excepted monitoring system) required by Section
225.240(a)(1).
For recertifications, the words "certification" and "initial certification" are
to be read as the word "recertification", the word "certified" is to be read as
the word "recertified", and the procedures set forth in Section 1.4(b)(5) of
Appendix B to this Part are to be followed in lieu of the procedures set forth
in subsection (a)(3)(E) of this Section.
A)
Notification of Certification. The owner or operator must submit written notice
of the dates of certification testing to the Agency directed to the Manager of
the Bureau of Air's Compliance Section, in accordance with Section
225.270.
B) Certification Application. The owner or
operator must submit to the Agency a certification application for each
monitoring system. A complete certification application must include the
information specified in
40 CFR
75.63, incorporated by reference in Section
225.140.
C) Provisional Certification Date. The
provisional certification date for a monitoring system must be determined in
accordance with Section 1.4(a)(3) of Appendix B to this Part. A provisionally
certified monitoring system may be used pursuant to this Subpart B for a period
not to exceed 120 days after receipt by the Agency of the complete
certification application for the monitoring system pursuant to subsection
(a)(3)(B) of this Section. Data measured and recorded by the provisionally
certified monitoring system, in accordance with the requirements of Appendix B
to this Part, will be considered valid quality-assured data (retroactive to the
date and time of provisional certification), provided that the Agency does not
invalidate the provisional certification by issuing a notice of disapproval
within 120 days after the date of receipt by the Agency of the complete
certification application.
D)
Certification Application Approval Process. The Agency must issue a written
notice of approval or disapproval of the certification application to the owner
or operator within 120 days after receipt of the complete certification
application required by subsection (a)(3)(B) of this Section. In the event the
Agency does not issue a written notice of approval or disapproval within the
120-day period, each monitoring system that meets the applicable performance
requirements of Appendix B to this Part and which is included in the
certification application will be deemed certified for use pursuant to this
Subpart B.
i) Approval Notice. If the
certification application is complete and shows that each monitoring system
meets the applicable performance requirements of Appendix B to this Part, then
the Agency must issue a written notice of approval of the certification
application within 120 days after receipt.
ii) Incomplete Application Notice. If the
certification application is not complete, then the Agency must issue a written
notice of incompleteness that sets a reasonable date by which the owner or
operator must submit the additional information required to complete the
certification application. If the owner or operator does not comply with the
notice of incompleteness by the specified date, the Agency may issue a notice
of disapproval pursuant to subsection (a)(3)(D)(iii) of this Section. The
120-day review period will not begin before receipt of a complete certification
application.
iii) Disapproval
Notice. If the certification application shows that any monitoring system does
not meet the performance requirements of Appendix B to this Part, or if the
certification application is incomplete and the requirement for disapproval
pursuant to subsection (a)(3)(D)(ii) of this Section is met, the Agency must
issue a written notice of disapproval of the certification application. Upon
issuance of such notice of disapproval, the provisional certification is
invalidated, and the data measured and recorded by each uncertified monitoring
system will not be considered valid quality-assured data beginning with the
date and hour of provisional certification (as defined pursuant to Section
1.4(a)(3) of Appendix B to this Part). The owner or operator must follow the
procedures for loss of certification set forth in subsection (a)(3)(E) of this
Section for each monitoring system that is disapproved for initial
certification.
iv) Audit
Decertification. The Agency may issue a notice of disapproval of the
certification status of a monitor in accordance with Section
225.260(c).
E) Procedures for Loss of
Certification. If the Agency issues a notice of disapproval of a certification
application pursuant to subsection (a)(3)(D)(iii) of this Section or a notice
of disapproval of certification status pursuant to subsection (a)(3)(D)(iv) of
this Section, the owner or operator must fulfill the following requirements:
i) The owner or operator must submit a
notification of certification retest dates and a new certification application
in accordance with subsections (a)(3)(A) and (B) of this Section.
ii) The owner or operator must repeat all
certification tests or other requirements that were failed by the monitoring
system, as indicated in the Agency's notice of disapproval, no later than 30
unit operating days after the date of issuance of the notice of
disapproval.
b) Exemption.
1) If an emissions monitoring system has been
previously certified in accordance with Appendix B to this Part and the
applicable quality assurance and quality control requirements of Section
1.5 and Exhibit B to
Appendix B to this Part are fully met, the monitoring system will be exempt
from the initial certification requirements of this Section.
2) The recertification provisions of this
Section apply to an emissions monitoring system required by Section
225.240(a)(1)
exempt from initial certification
requirements pursuant to subsection (a)(1) of this Section.
c) Initial certification and recertification procedures for EGUs using the mercury low mass emissions excepted methodology pursuant to Section 1.15(b) of Appendix B to this Part. The owner or operator that has elected to use the mercury-low-mass-emissions-excepted methodology for a qualified EGU pursuant to Section 1.15(b) to Appendix B to this Part must meet the applicable certification and recertification requirements in Section 1.15(c) through (f) to Appendix B to this Part.
d) Certification Applications. The owner or operator of an EGU must submit an application to the Agency within 45 days after completing all initial certification or recertification tests required pursuant to this Section, including the information required pursuant to 40 CFR 75.63, incorporated by reference in Section 225.140.
