Compliance with §115.152 of this title (relating to Control Requirements) shall be determined by applying the following test methods, as appropriate:
  (1) Test Methods 1-4 (40 CFR 60, Appendix A) for determining flow rate, oxygen concentration, or moisture, as necessary;
  (2) Test Method 2E as proposed under 40 CFR 60, Appendix A, published in the May 30, 1991, issue of the Federal Register (58 FR 104) for designing the area of influence of the gas collection and control system (GCCS);
  (3) Test Method 3C as proposed under 40 CFR 60, Appendix A, published in the May 30, 1991, issue of the Federal Register (58 FR 104) for measuring the concentration of nitrogen in the landfill gas;
  (4) Test Method 18 (40 CFR 60, Appendix A) for determining gaseous organic compound emissions by gas chromatography;
  (5) Test Method 21 (40 CFR 60, Appendix A) for determining volatile organic compound leaks;
  (6) Test Method 25 (40 CFR 60, Appendix A) for determining total gaseous non-methane (CH4 ) organic emissions as carbon;
  (7) Test Methods 25A or 25B (40 CFR 60, Appendix A) for determining total gaseous organic concentrations using flame ionization or nondispersive infrared analysis;
  (8) Test Method 25C as proposed under 40 CFR 60, Appendix A, published in the May 30, 1991, issue of the Federal Register (58 FR 104) for determining non-CH4 organic compounds in landfill gases;
  (9) determination of true vapor pressure using American Society for Testing and Materials Test Methods D323-89, D2879, D4953, D5190, or D5191 for the measurement of Reid vapor pressure, adjusted for actual storage temperature in accordance with American Petroleum Institute Publication 2517, Third Edition, 1989;
  (10) one of the above test methods with minor modifications as approved by the executive director.
