Illinois Administrative Code › Title 35 - ENVIRONMENTAL PROTECTION › Part 225 - CONTROL OF EMISSIONS FROM LARGE COMBUSTION SOURCES › Subpart B - CONTROL OF MERCURY EMISSIONS FROM COAL-FIRED ELECTRIC GENERATING UNITS › Section 225.250 - Initial Certification and Recertification Procedures for Emissions Monitoring

Current through Register Vol. 48, No. 28, July 12, 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.
