Table 40 to Subpart UUU of Part 63—Requirements for Installation, Operation, and Maintenance of Continuous Opacity Monitoring Systems and Continuous Emission Monitoring Systems
As stated in § 63.1572(a)(1) and (b)(1), you shall meet each requirement in the following table that applies to you.
This type of continuous opacity or emission monitoring system . . . Must meet these requirements . . .
1. Continuous opacity monitoring system Performance specification 1 (40 CFR part 60, appendix B).
2. CO continuous emission monitoring system Performance specification 4 (40 CFR part 60, appendix B); span value of 1,000 ppm; and procedure 1 (40 CFR part 60, appendix F) except relative accuracy test audits are required annually instead of quarterly.
3. CO continuous emission monitoring system used to demonstrate emissions average under 50 ppm (dry basis). Performance specification 4 (40 CFR part 60, appendix B); and span value of 100 ppm.
4. SO2 continuous emission monitoring system for sulfur recovery unit with oxidation control system or reduction control system; this monitor must include an O2 monitor for correcting the data for excess air. Performance specification 2 (40 CFR part 60, appendix B); span value of 500 ppm SO2; use Methods 6 or 6C and 3A or 3B (40 CFR part 60, appendix A) for certifying O2 monitor; and procedure 1 (40 CFR part 60, appendix F) except relative accuracy test audits are required annually instead of quarterly.
5. Reduced sulfur and O2 continuous emission monitoring system for sulfur recovery unit with reduction control system not followed by incineration; this monitor must include an O2 monitor for correcting the data for excess air unless exempted. Performance specification 5 (40 CFR part 60, appendix B), except calibration drift specification is 2.5 percent of the span value instead of 5 percent; 450 ppm reduced sulfur; use Methods 15 or 15A and 3A or 3B (40 CFR part 60, appendix A) for certifying O2monitor; if Method 3A or 3B yields O2 concentrations below 0.25 percent during the performance evaluation, the O2 concentration can be assumed to be zero and the O2 monitor is not required; and procedure 1 (40 CFR part 60, appendix F), except relative accuracy test audits, are required annually instead of quarterly.
6. Instrument with an air or O2 dilution and oxidation system to convert reduced sulfur to SO2 for continuously monitoring the concentration of SO2 instead of reduced sulfur monitor and O2 monitor. Performance specification 5 (40 CFR part 60, appendix B); span value of 375 ppm SO2; use Methods 15 or 15A and 3A or 3B for certifying O2 monitor; and procedure 1 (40 CFR part 60, appendix F), except relative accuracy test audits, are required annually instead of quarterly.
7. TRS continuous emission monitoring system for sulfur recovery unit; this monitor must include an O2 monitor for correcting the data for excess air. Performance specification 5 (40 CFR part 60, appendix B).
8. O2 monitor for oxygen concentration. If necessary due to interferences, locate the oxygen sensor prior to the introduction of any outside gas stream; performance specification 3 (40 CFR part 60, appendix B; and procedure 1 (40 CFR part 60, appendix F), except relative accuracy test audits, are required annually instead of quarterly.
