N.M. Code R. § 20.2.31.111 – Compliance

A. Compliance with the emission limitations contained within this Part shall be determined by a method consistent with the manual method of sampling for sulfur dioxide set forth by the Environmental Protection Agency at 40 CFR, Part 60 Appendix A, Methods 1 through 4 and 6, except for the thirty-day average and the station requirements contained within subsections C and D of 20.2.31.109 NMAC, and subsection A and paragraph (1) of subsection B of 20.2.31.110 NMAC in which the determination of compliance shall be based upon continuous emissions monitoring as required by 20.2.31.112 NMAC. Compliance with the percentage removal requirements of 20.2.31.110 NMAC shall be determined based upon continuous monitoring of sulfur dioxide concentrations within the flue gases both prior to entering the sulfur dioxide removal system and at all locations at which sulfur dioxide emissions are released to the atmosphere, unless the Department has approved an alternative means of determining sulfur dioxide concentrations prior to the sulfur dioxide removal system.
B. Compliance with the pounds per hour station emission limitation contained within paragraph (2) of subsection B of 20.2.31.110 NMAC shall be determined as follows: Individual stacks serving existing coal burning equipment shall be sampled by use of the manual sampling method for sulfur dioxide referenced above. Emissions in excess of the approved individual emission limitation applicable to a specific stack shall be deemed a violation of this Part unless the owner or operator demonstrates to the satisfaction of the Department, by continuous stack emission monitoring or other means, that the total sulfur dioxide emissions from all stacks serving existing coal burning equipment within the station do not exceed 17,900 pounds per hour.
