Table 5 to Subpart WWWW—Performance Test Requirements for Compliance With Emissions Limits Under § 60.6450

To determine compliance with the . . .You must conduct a performance test to . . .Using . . .
Particulate matter emission limits1. Select sampling ports location and the number of traverse points . . .Method 1 in appendix A-1 to part 60 of this chapter.
2. Determine oxygen and carbon dioxide concentrations of the stack gas . . .Method 3A or 3B in appendix A-2 to part 60 of this chapter, or as an alternative the manual method portion of ASME PTC-19-10-1981—part 10.
3. Measure the particulate matter emission concentration to determine compliance with the particulate matter emission limit to part 60 of this chapter . . .Method 5 in appendix A-3 to part 60 of this chapter.

Collect a minimum sample volume of 1.7 cubic meters. The probe and filter holder heating systems in the sample train shall be set to provide a gas temperature no greater than 160 °C. An oxygen or carbon dioxide measurement shall be obtained simultaneously with each Method 5 run.
Opacity emission limitsDetermine compliance with the opacity limit in Table 3 to Subpart WWWW . . .Method 9 of appendix A-4 of part 60 to this chapter, except as provided under § 60.11(e) of subpart A of this part, or as an alternative ASTM D7520-16 provided the digital camera opacity technique conditions, as defined in this subpart, are met.
Cadmium or lead emission limits1. Select sampling ports location and the number of traverse pointsMethod 1 in appendix A-1 to part 60 of this chapter.
2. Determine oxygen and carbon dioxide concentrations of the stack gas for flue gas analysis . . .Method 3A or 3B in appendix A-2 to part 60 of this chapter, or as an alternative the manual method portion of ASME PTC-19-10-1981—part 10.
3. Measure the cadmium or lead emission concentration to determine compliance with the emission limits . . .Method 29 in appendix A-8 to part 60 of this chapter. An oxygen or carbon dioxide measurement shall be obtained simultaneously with each Method 29 test run for cadmium and lead required.
Mercury emission limits1. Select sampling ports location and the number of traverse points . . .Method 1 in appendix A-1 to part 60 of this chapter.
2. Determine oxygen and carbon dioxide concentrations of the stack gas for flue gas analysis . . .Method 3A or 3B in appendix A-2 to part 60 of this chapter, or as an alternative the manual method portion of ASME PTC-19-10-1981—part 10.
3. Measure the mercury emission concentration to determine compliance with the emission limits . . .Method 29 in appendix A-8 to part 60 of this chapter or as an alternative ASTM D6784-24. Collect a minimum sample volume of 1.7 cubic meters.

An oxygen or carbon dioxide measurement shall be obtained simultaneously with each Method 29 test run for mercury required.
Sulfur dioxide emission limitsCalculate the 24-hr daily geometric average sulfur dioxide emission concentration . . .Method 19, section 12.4.3, in appendix A-7 to part 60 of this chapter.
Hydrogen chloride emission limitsMeasure the hydrogen chloride emission concentration . . .Method 26 or 26A in appendix A-8 of part 60 to this chapter, as applicable. The minimum sampling time shall be 1 hour. An oxygen (or carbon dioxide) measurement shall be obtained simultaneously with each Method 26 or 26A test run for hydrogen chloride.
Dioxins/furans emission limits1. Select sampling ports location and the number of traverse points . . .
2. Determine oxygen and carbon dioxide concentrations of the stack gas for flue gas analysis . . .Method 3, 3A or 3B in appendix A-2 to part 60 of this chapter, or as an alternative ASME PTC-19-10-1981—part 10.
3. Measure the dioxins/furans emission concentration to determine compliance with the emission limits . . .Method 23 in appendix A-7 to part 60 of this chapter. The minimum sampling time shall be 4 hours. An oxygen (or carbon dioxide) measurement shall be obtained simultaneously with each Method 23 test run for dioxins/furans.
Nitrogen oxides emission limitsDetermine the daily arithmetic average nitrogen oxides emission concentration.Method 19, section 12.4.1, in appendix A-7 to part 60 of this chapter.
Fugitive ash emission limitsMeasure fugitive ash emissions . . .Method 22 in appendix A-7 to part 60 of this chapter. The minimum observation time shall be a series of three 1-hour observations. The observation period shall include times when the facility is transferring ash from the municipal waste combustor to the area where ash is stored or loaded into containers or trucks.
Opacity limit for air curtain incinerators under § 60.6665Determine compliance with the opacity limit in § 60.6665Method 9 of appendix A-4 of part 60 to this chapter, or as an alternative ASTM D7520-16 provided the digital camera opacity technique conditions, as defined in this subpart, are met.
