Current through Register Vol. 35, No. 18, September 24, 2024

Compliance with 20.2.17.109 NMAC shall be determined by a method consistent with the method set forth by the US EPA at 40 CFR, Part 60, Appendix A, Methods 1 through 5, except that Method 5 is modified as follows: The distilled water specified in the first impinger of Method 5 is replaced with isopropyl alcohol solution as specified within Method 8 of 40 CFR, Part 60, Appendix A. The temperature of the probe and oven containing the cyclone and filter should be maintained above the dew point of sulfuric acid mist in order to prevent condensation of acid mist within the probe or on the filter. After sample collection, the isopropyl alcohol solution within the first impinger is analyzed for sulfur trioxide and sulfuric acid mist as described in Method 8. Solid particulate matter is collected within the nozzle, isopropyl alcohol impinger. Compliance with 20.2.17.109 NMAC shall be determined by comparison of the sum of the solid and liquid particulate matter to the applicable emission limitation.
