8-34-600 MANUAL OF PROCEDURES

8-34-601 Determination of Emissions: Emissions of non-methane organic compounds as specified in Section 8-34-301 shall be measured as prescribed by any of the following methods: BAAQMD Manual of Procedures, Volume IV, ST-7 and ST-14 or EPA Reference Methods 18, 25, 25A, or 25C (40 CFR 60, Appendix A). If Method 18 is used, the minimum list of compounds to be tested shall be those published in the most recent Compilation of Air Pollution Emission Factors (AP-42). A source shall be considered in violation if the NMOC emissions measured by any of the referenced test methods exceed the standards of this rule. For the purposes of determining compliance using ST-7, NMOC is the same as organic compounds. (Amended Nov. 17, 1993; Jun. 15, 1994; Oct. 6, 1999)

8-34-602 Collection and Control System Leak Inspection Procedures: For the purposes of Section 8-34-301.2, leaks shall be measured using a portable gas detector as prescribed in EPA Reference Method 21 (40 CFR 60, Appendix A). (Adopted Nov. 17, 1993; Amended Jul. 17, 1996; Oct. 6, 1999)

8-34-603 Landfill Gas Sampling Procedure: For the purposes of Sections 8-34-121.2, 406, 407 or 408, landfill gas samples, which are necessary for determining landfill gas production rate or a site-specific k value, shall be taken either from existing wells or from temporary wells that meet the requirements specified in EPA Reference Method 2E (40 CFR 60, Appendix A). Landfill gas sampling for other purposes shall be performed according to BAAQMD Manual of Procedures, Volume IV, Part 1 or ST-7, or EPA Reference Methods 18, 25, 25A, or 25C (40 CFR 60, Appendix A). If Method 18 is used, the minimum list of compounds to be tested shall be those published in the most recent Compilation of Air Pollution Emission Factors (AP-42). (Adopted Nov. 17, 1993; Amended Jul. 17, 1996; Oct. 6, 1999)

8-34-604 Determination of Concentration: For the purposes of Sections 8-34-121.2, 305, 404, 406, 407, or 408, the percentage concentration of carbon dioxide, methane, nitrogen, or oxygen in the landfill gas shall be determined as prescribed in EPA Reference Method 3C (40 CFR 60, Appendix A).

The probe shall be placed 5 centimeters (2 inches) above the ground. Monitoring shall be performed under the meteorological conditions specified in BAAQMD Manual of Procedures. The background concentration shall be determined as specified in BAAQMD Manual of Procedures. In accordance with the provisions of 40 CFR 60.753(d) and 60.755(c)(1-3), the entire perimeter of the landfill surface shall be inspected. The interior landfill shall be inspected along a pattern that traverses the landfill in 30 meter intervals or other APCO approved site-specific spacing. Landfill surface areas with distressed vegetation, cracks or seeps shall also be inspected. Steep slopes and other dangerous areas may be excluded from landfill surface inspection.
