The owner or operator of any existing or modified nonferrous smelter shall not permit, cause, suffer or allow:

A. Annual average emissions in excess of 7000 pounds of sulfur dioxide per hour except as provided for in 20.2.41.112 NMAC;

B. A median 3-hour running average to exceed 5309 pounds of sulfur dioxide per hour during any 365-day compliance period;

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:

(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.
