Section 20.2.31.109 - NEW EQUIPMENT

New coal burning equipment is subject to the following requirements:

A. The owner or operator of Vintage 4 new coal burning equipment having a power generating capacity in excess of 25 megawatts or a rated heat input of greater than 250 million British Thermal Units per hour (higher heating value) shall not permit, cause, suffer or allow sulfur dioxide emissions to the atmosphere in excess of 0.34 pounds per million British Thermal Units of heat input (higher heating value) averaged over a 3 hour period.

B. The owner or operator of Vintage 1, 2, or 3 new coal burning equipment having a power generating capacity in excess of 25 megawatts or a heat input of greater than 250 million British Thermal Units per hour (higher heating value) shall not permit, cause, suffer or allow sulfur dioxide emissions to the atmosphere in excess of 1.2 pounds per million British Thermal Units of heat input (higher heating value) averaged over a 3 hour period as determined by 20.2.31.111 NMAC, which emission limitation shall apply, effective January 1, 1983 and thereafter, to these vintage units.

C. The owner or operator of a station consisting of any combination of at least one Vintage l, 2, or 3 new and existing coal burning equipment, after December 31, 1982, shall not permit, cause, suffer or allow sulfur dioxide emissions to the atmosphere in excess of 0.55 pounds per million British Thermal Units of heat input (higher heating value) averaged over a thirty day period, and in excess of 13,000 pounds per hour averaged over a three hour period, both determined on a total station basis. Existing coal burning equipment in a station with Vintage 1, 2, or 3 units must continue to meet the requirements of 20.2.31.110 NMAC.

D. If the owner or operator of a station consisting of any combination of at least one Vintage 1, 2, or 3 new and existing coal burning equipment, in the optimum operation of their sulfur dioxide equipment, cannot meet on a continuous basis with a two module operation per unit, excluding upset conditions, the 0.55 pounds per million British Thermal Units requirement, then in that event such station shall, after a showing of its inability to do so to the Board, in no event permit, cause, suffer or allow sulfur dioxide emissions to the atmosphere, in excess of 0.65 pounds per million British Thermal Units of heat input, averaged over a thirty day period, but shall continue to meet the 13,000 pounds per hour averaged over a three hour period that is required by subsection C of 20.2.31.109 NMAC. Additionally, existing coal burning equipment must continue to meet the requirements of 20.2.31.110 NMAC.
