Section 74:36:07:110 - Initial control system performance test for existing municipal solid waste landfill The owner or operator shall conduct an initial performance test to be completed no later than 180 days after the initial startup of the approved control system. The performance test is not required for boilers and process heaters with design heat input capacities equal to or greater than 44 megawatts that burns the landfill gas. The owner or operator shall use the following test methods:
(1) For a non-enclosed flare, the net heating value of the combusted landfill gas, as determined in 40 C.F.R. § 60.18(f)(3) (July 1, 2018), is calculated from the concentration of methane in the landfill gas as measured by 40 C.F.R. Part 60, Appendix A, Method 3C (July 1, 2018). A minimum of three 30-minute Method 3C samples are determined. The measurement of other organic components, hydrogen, and carbon monoxide is not applicable. Method 3C may be used to determine the landfill gas molecular weight for calculating the flare gas exit velocity under 40 C.F.R. § 60.18(4) (July 1, 2018);(2) 40 C.F.R. Part 60, Appendix A, Method 25 or 25C (July 1, 2018) shall be used to determine compliance with the 98 percent by weight efficiency or the 20 parts per million by volume outlet nonmethane organic compound concentration level, unless another method to demonstrate compliance has been approved by the Secretary. Method 25C may be used at the inlet only. 40 C.F.R. Part 60, Appendix A, Method 3, 3A, or 3C (July 1, 2018) shall be used to determine oxygen for correcting the nonmethane organic compound concentration as hexane to three percent. In cases where the outlet concentration is less than 50 parts per million nonmethane organic compound as carbon (8 parts per million nonmethane organic compound as hexane), 40 C.F.R. Part 60, Appendix A, Method 25A (July 1, 2018) should be used in place of Method 25. 40 C.F.R. Part 60, Appendix A, Method 18 (July 1, 2018) may be used in conjunction with Method 25A on a limited basis or Method 3C may be used to determine methane. The methane as carbon should be subtracted from the Method 25A total hydrocarbon value as carbon to give nonmethane organic compound concentration as carbon. The owner or operator shall divide the nonmethane organic compound concentration as carbon by six to convert the nonmethane organic compound concentration as carbon to nonmethane organic compound concentration as hexane. The following equation shall be used to calculate efficiency: Control efficiency =(NMOCin - NMOCout)/NMOCin where
NMOCin = Mass of nonmethane organic compounds entering control device; and
NMOCout = Mass of nonmethane organic compounds exiting control device;
Within 60 days after the date of completing each performance test, the owner or operator shall submit the results of the performance tests, including any associated fuel analyses.
