N.M. Code R. § 20.2.41.109
The owner or operator of any existing or modified nonferrous smelter shall not permit, cause, suffer or allow:
C. More than N occurrences of three-hour running average sulfur dioxide emissions in excess of the corresponding E values shown in the following table in any 365-day compliance period when there are malfunction or startup conditions:
N (number of occurrences) E (pounds per hour of sulfur dioxide emissions) 0 3,000 1 49,000 2 45,500 4 42,300 7 39,200 12 36,200 20 33,400 32 31,300 48 29,200 68 27,200 94 25,600 130 23,800 180 21,700 245 20,000 330 18,700 435 17,200 560 15,800 710 14,600 890 13,200 1100 12,200 [greater than] 1100 7,800

(1) Any three-hour average that includes a period of time when there are malfunction or startup conditions shall be included in either the cumulative occurrence limits of subsections C and D of 20.2.41.109 NMAC, at the choice of the smelter owner or operator;
(2) Any three-hour average that does not include a period of time when there are malfunction or startup conditions shall be included in the cumulative occurrence table in subsection D of 20.2.41.109 NMAC.
E. The release of fugitive sulfur emissions to the atmosphere unless the owner or operator utilizes best engineering practices to minimize the release of such fugitive emissions. Best engineering practices shall, as a minimum, include:
(1) Maintaining and operating all furnaces, converters, and converter hoods so that leakage of gases to the atmosphere will be minimized to the maximum extent practicable;
(2) Maintaining all ducts, flues, and stacks in leak-free condition;
(3) Installing and operating tight-fitting exhaust hoods where feasible on all tapholes, launders, and other significant sources of fugitive sulfur emissions; and
(4) Venting all captured fugitive emissions through the tallest stack serving the smelter;
F. Operation of the smelter without including all measured emissions to the atmosphere in compliance calculations.
