§ 63.4166 How do I determine the add-on control device emission destruction or removal efficiency?

(a) For all types of add-on control devices, use the test methods as specified in paragraphs (a)(1) through (5) of this section.

(1) Use Method 1 or 1A in appendix A–1 of part 60, as appropriate, to select sampling sites and velocity traverse points.

(2) Use Method 2, 2A, 2C, 2D, or 2F in appendix A–1, or Method 2G in appendix A–2, of part 60, as appropriate, to measure gas volumetric flow rate.

(3) Use Method 3, 3A, or 3B in appendix A–2 of part 60, as appropriate, for gas analysis to determine dry molecular weight. You may also use as an alternative to Method 3B, the manual method for measuring the oxygen, carbon dioxide, and carbon monoxide content of exhaust gas in ANSI/ASME, PTC 19.10–1981, “Flue and Exhaust Gas Analyses” (incorporated by reference, see § 63.14).

(4) Use Method 4 in appendix A–3 of part 60 to determine stack gas moisture.

(5) Methods for determining gas volumetric flow rate, dry molecular weight, and stack gas moisture must be performed, as applicable, during each test run.
