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 225.240 - General Monitoring and Reporting Requirements

Current through Register Vol. 48, No. 28, July 12, 2024
Except as otherwise indicated in this Subpart, the owner or
				  operator of an EGU must comply with the monitoring, recordkeeping, and
				  reporting requirements as provided in this Section, Sections
				  225.250
				  through
				  225.290
				  of this Subpart B, and Sections 1.14 through 1.18 of Appendix B to this Part.
				  If the EGU utilizes a common stack with units that are not EGUs and the owner
				  or operator of the EGU does not conduct emissions monitoring in the duct to the
				  common stack from each EGU, the owner or operator of the EGU must conduct
				  emissions monitoring in accordance with Section 1.16(b)(2) of Appendix B to
				  this Part and this Section, including monitoring in the duct to the common
				  stack from each unit that is not an EGU, unless the owner or operator of the
				  EGU counts the combined emissions measured at the common stack as the mass
				  emissions of mercury for the EGUs for recordkeeping and compliance
				  purposes.
a) Requirements for
				installation, certification, and data accounting. The owner or operator of each
				EGU must:
1) Install all monitoring systems
				required pursuant to this Section and Sections
				225.250
				through
				225.290
				for monitoring mercury mass emissions (including all systems required to
				monitor mercury concentration, stack gas moisture content, stack gas flow rate,
				and CO2 or O2 concentration, as
				applicable, in accordance with Sections
				1.15
				and 1.16 of Appendix B to this Part).
2) Successfully complete all certification
				tests required pursuant to Section
				225.250
				and meet all other requirements of this Section, Sections
				225.250
				through 225.290, and Sections 1.14 through 1.18 of Appendix B to this Part
				applicable to the monitoring systems required under subsection (a)(1) of this
				Section.
3) Record, report, and
				assure the quality of the data from the monitoring systems required under
				subsection (a)(1) of this Section.
4) If the owner or operator elects to use the
				low mass emissions excepted monitoring methodology for an EGU that emits no
				more than 464 ounces (29 pounds) of mercury per year pursuant to Section
				1.15(b)
				of Appendix B to this Part, it must perform emissions testing in accordance
				with Section
				1.15(c)
				of Appendix B to this Part to demonstrate that the EGU is eligible to use this
				excepted emissions monitoring methodology, as well as comply with all other
				applicable requirements of Section
				1.15(b)
				through (f) of Appendix B to this Part. Also,
				the owner or operator must submit a copy of any information required to be
				submitted to the USEPA pursuant to these provisions to the Agency. The initial
				emissions testing to demonstrate eligibility of an EGU for the low mass
				emissions excepted methodology must be conducted by the applicable of the
				following dates:
A) If the EGU has commenced
				commercial operation before July 1, 2008, at least by July 1, 2009, or 45 days
				prior to relying on the low mass emissions excepted methodology, whichever date
				is later.
B) If the EGU has
				commenced commercial operation on or after July 1, 2008, at least 45 days prior
				to the applicable date specified pursuant to subsection (b)(2) of this Section
				or 45 days prior to relying on the low mass emissions excepted methodology,
				whichever date is later.
