South Dakota Administrative Rules › Title 74 - Department of Environment And Natural Resources › Article 74:36 - Air pollution control program › Chapter 74:36:07 - New source performance standards › Section 74:36:07:110 - Initial control system performance test for existing municipal solid waste landfill

Current through Register Vol. 51, page 10, July 15, 2024
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.
