Table 3 to Subpart VVVV of Part 60—Requirements for Continuous Emission Monitoring Systems (CEMS)

For the following

pollutants		Use the following

span values for your CEMS		Use the following

performance specifications for your CEMS		During each relative

accuracy test run,

use the following methods

to collect concurrent data
1. Particulate MatterFor operation and correlation test, P.S. 11 in appendix B of this part and procedure 2 of appendix F to this part.Follow the test methods in Table 4 to Subpart VVVV.
For quarterly accuracy determinations, daily calibration drift tests, and each response correlation audit or relative response audit, procedure 2 of appendix F to this part
2. Nitrogen OxidesControl device outlet: 125 percent of the maximum estimated hourly nitrogen oxides emissions of the municipal waste combustorFor operation, P.S. 2 in appendix B of this part and procedure 1 of appendix F of this part

For relative accuracy, P.S. 2 in appendix B of this part and procedure 1 of appendix F of this part		Method 7, 7A, 7C, 7D, or 7E in appendix A-4 to part 60 of this chapter.
For quarterly accuracy determinations and daily calibration drift tests, procedure 1 in appendix F of this part
3. Sulfur DioxideControl device outlet: 50 percent of the maximum estimated hourly sulfur dioxide emissions of the municipal waste combustorFor operation, P.S. 2 in appendix B of this part and procedure 1 of appendix F of this part

For relative accuracy audit, P.S. 2 in appendix B of this part and procedure 1 of appendix F of this part		Method 6, 6A, or 6C in appendix A-4 to part 60 of this chapter.
For quarterly accuracy determinations and daily calibration drift tests, procedure 1 in appendix F of this part
4. Carbon Monoxide125 percent of the maximum estimated hourly carbon with monoxide emissions of the municipal waste combustorFor operation, P.S. 4A in appendix B of this part and procedure 1 of appendix F of this part

For relative accuracy audit, P.S. 4A in appendix B of this part and procedure 1 of appendix F of this part		Method 10, 10A, or 10B in appendix A-4 to part 60 of this chapter.
For quarterly accuracy determinations and daily calibration drift tests, procedure 1 in appendix F of this part
5. Oxygen or Carbon Dioxide25 percent oxygen or 20 percent carbon dioxideP.S. 3 in appendix B of this partMethod 3A, or 3B in appendix A-2 to part 60 of this chapter, or, as an alternative for oxygen or carbon dioxide correction, the manual method portion of ASME PTC-19-10-1981—part 10.
6. MercuryFollow the approved site-specific monitoring planFor operation, P.S. 12A in appendix B of this part and procedure 5 of appendix F of this part, or the approved site-specific monitoring planFollow the test methods in Table 4 to Subpart VVVV.
For relative accuracy audit, daily calibration, weekly system integrity check, quarterly audit, procedure 5 of appendix F of this part
7. Hydrogen chlorideFollow the approved site-specific monitoring planFor operation, P.S. 18 in appendix B of this part and procedure 6 of appendix F of this part or the approved site-specific monitoring planFollow the test methods in Table 4 to Subpart VVVV, except you may also use Methods 320 or 321 of appendix A to part 63.
For relative accuracy audit, daily calibration, quarterly audit, and other applicable quality assurance/quality control checks procedure 6 of appendix F of this part
8. Cadmium or LeadFollow the approved site-specific monitoring planFor operation, the approved site-specific monitoring planFollow the test methods in Table 4 to Subpart VVVV.
