Section Env-A 803.04 - Test Methods for Compliance Stack Testing for NOx(a) Subject to (b), below, the following test methods shall be used for the compliance stack testing required by Env-A 803.02 and Env-A 803.03, as applicable: (1) Method 7, 7A, 7C, 7D, or 7E as described in 40 CFR 60, Appendix A, to determine NOx concentrations in stack gases;(2) Method 10 as described in 40 CFR 60, Appendix A, to determine carbon monoxide concentrations in stack gases;(3) Method 1 and Method 2, 2C, 2F, 2G, or 2H, as described in 40 CFR 60, Appendix A, to determine the exit flow rate of stack gases;(4) Method 3 or 3A as described in 40 CFR 60, Appendix A, to determine carbon dioxide, oxygen, excess air and molecular weight, dry basis, of stack gases; and(5) Method 4 as described in 40 CFR 60, Appendix A, to determine the volume fraction of water vapor in stack gases.(b) The owner or operator may use Method 20 as described in 40 CFR 60, Appendix A, in lieu of the methods identified in (a), above, to determine NOx concentrations in stationary gas turbine stack gases.N.H.
