40 CFR Appendix Table 3 to Subpart MMMMM of Part 63 - Table 3 to Subpart MMMMM of Part 63—Performance Test Requirements for Existing, New, or Reconstructed Flame Lamination Affected Sources

As stated in § 63.8800, you must comply with the requirements for performance tests for flame lamination affected sources in the following table using the requirements in rows 1 through 5 of the table if you are measuring HCl and using a scrubber, row 6 for new or reconstructed sources measuring HCN and using a scrubber, and row 7 if you are using any other control device. For existing sources not using a control device, you must comply with row 8 and rows 1 through 4 of the table.

For each new or reconstructed flame lamination affected source, you must . . .	Using . . .	According to the following requirements . . .
1. Select sampling port's location and the number of traverse ports	Method 1 or 1A in appendix A to part 60 of this chapter	Sampling sites must be located at the inlet and outlet of the scrubber and prior to any releases to the atmosphere.
2. Determine velocity	Method 2, 2A, 2C, 2D, 2F, or 2G in appendix A to part 60 of this chapter.
3. Determine gas molecular weight	Not applicable	Assume a molecular weight of 29 (after moisture correction) for calculation purposes.
4. Measure moisture content of the stack gas	Method 4 in appendix A to part 60 of this chapter.
5. Measure HCl concentration	Method 26A in appendix A to part 60 of this chapter	i. For new or reconstructed sources, determine the HCl reduction efficiency of the control device using Method 26A and the procedures specified in § 63.8800(e).
		ii. For existing sources, determine the HCl emission rate using Method 26A and the procedures specified in § 63.8800(f). iii. Collect scrubber liquid flow rate, scrubber effluent pH, and pressure drop (pressure drop data only required for venturi scrubbers) every 15 minutes during the entire duration of each 1-hour test run, and determine the average scrubber liquid flow rate, scrubber effluent pH, and pressure drop (pressure drop data only required for venturi scrubbers) over the period of the performance test by computing the average of all 15-minute readings.
6. Measure HCN concentration	A method approved by the Administrator	i. Conduct the performance test according to the site-specific test plan submitted according to § 63.7(c)(2)(i). Measure total HCN emissions and determine the reduction efficiency of the control device. Any performance test which measures HCN concentrations must be submitted for the administrator's approval prior to testing. You must use EPA Method 301 (40 CFR part 63, Appendix A) to validate your method.
		ii. Collect scrubber liquid flow rate, scrubber effluent pH, and pressure drop (pressure drop data only required for venturi scrubbers) every 15 minutes during the entire duration of each 1-hour test run, and determine the average scrubber liquid flow rate, scrubber effluent pH, and pressure drop (pressure drop data only required for venturi scrubbers) over the period of the performance test by computing the average of all 15-minute readings.
7. If you use any control device other than a scrubber, establish operating parameter limits with which you will demonstrate continuous compliance with the emission limit that applies to the source	EPA-approved methods and data from the continuous parameter monitoring system	i. Conduct the performance test according to the site-specific test plan submitted according to § 63.7(c)(2)(i).
		ii. For new or reconstructed sources, determine the HCl or HCN reduction efficiency of the control device using the EPA-approved method and the procedures specified in § 63.8800(e).
		iii. For existing sources, determine the HCl emission rate using the EPA-approved method and the procedures specified in § 63.8800(f). iv. Collect operating parameter data as specified in the site-specific test plan.
8. Measure HCl concentration	Method 26A in appendix A to part 60 of this chapter	Determine the HCl emission rate using the appropriate test methods and the procedures specified in § 63.8800(f).
