Illinois Administrative Code › Title 35 - ENVIRONMENTAL PROTECTION › Part 225 - CONTROL OF EMISSIONS FROM LARGE COMBUSTION SOURCES › Subpart F - COMBINED POLLUTANT STANDARDS › Appendix B - Continuous Emission Monitoring Systems for Mercury › Exhibit B - Quality Assurance and Quality Control Procedures

Current through Register Vol. 48, No. 28, July 12, 2024
1. Quality Assurance/Quality Control Program
Develop and implement a quality assurance/quality control
					 (QA/QC) program for the continuous emission monitoring systems and their
					 components. At a minimum, include in each QA/QC program a written plan that
					 describes in detail (or that refers to separate documents containing) complete,
					 step-by-step procedures and operations for each of the following activities.
					 Upon request from regulatory authorities, the source must make all procedures,
					 maintenance records, and ancillary supporting documentation from the
					 manufacturer (e.g., software coefficients and troubleshooting diagrams)
					 available for review during an audit. Electronic storage of the information in
					 the QA/QC plan is permissible, provided that the information can be made
					 available in hardcopy upon request during an audit.
1.1 Requirements for All Monitoring Systems
1.1.1 Preventive Maintenance
Keep a written record of procedures needed to maintain the
					 monitoring system in proper operating condition and a schedule for those
					 procedures. This must, at a minimum, include procedures specified by the
					 manufacturers of the equipment and, if applicable, additional or alternate
					 procedures developed for the equipment.
1.1.2 Recordkeeping and Reporting
Keep a written record describing procedures that will be
					 used to implement the recordkeeping and reporting requirements in subparts E
					 and G of 40 CFR 75, incorporated by reference in Section 225.140, and Sections
					 1.10 through 1.13 of Appendix B, as applicable.
1.1.3 Maintenance Records
Keep a record of all testing, maintenance, or repair
					 activities performed on any monitoring system or component in a location and
					 format suitable for inspection. A maintenance log may be used for this purpose.
					 The following records should be maintained: date, time, and description of any
					 testing, adjustment, repair, replacement, or preventive maintenance action
					 performed on any monitoring system and records of any corrective actions
					 associated with a monitor's outage period. Additionally, any adjustment that
					 recharacterizes a system's ability to record and report emissions data must be
					 recorded (e.g., changing of flow monitor or moisture monitoring system
					 polynomial coefficients, K factors or mathematical algorithms, changing of
					 temperature and pressure coefficients and dilution ratio settings), and a
					 written explanation of the procedures used to make the adjustments must be
					 kept.
1.1.4
The requirements in Section 6.1.2 of Exhibit A to Appendix
					 B must be met by any Air Emissions Testing Body (AETB) performing the
					 semiannual/annual RATAs described in Section 2.3 of this Exhibit and the
					 mercury emission tests described in Sections 1.15(c) and 1.15(d)(4) of Appendix
					 B.
