NAC445B.22047. Sulfur emissions: Fuel-burning equipment.

     1. No person may cause or permit the emission of compounds of sulfur caused by the combustion of fuel in fuel-burning equipment in excess of the quantity calculated by the use of the formula in subsection 2 or 3.

     2. Where an emission unit has a maximum input of heat of less than 250 million Btu’s per hour, the allowable emission must be calculated by the use of the following equation:

Y = 0.7X

For the purposes of this subsection:

     (a) “X” means the maximum operating input of heat in millions of Btu’s per hour.

     (b) “Y” means the allowable rate of emission of sulfur in pounds per hour.

     3. Where an emission unit has a maximum input of heat equal to or greater than 250 million Btu’s per hour, the allowable emission of sulfur must be calculated by the use of the following equations:

Liquid fuel	Y = 0.4X
Solid fuel	Y = 0.6X
Combination Fuel		Y=	L (0.4X) + S (0.6X) L + S

For the purposes of this subsection:

     (a) “X” means the maximum input of the operation in millions of Btu’s per hour.

     (b) “Y” means the allowable rate of emissions of sulfur in pounds per hour.

     (c) “L” means the percentage of total input of heat derived from liquid fuel.

     (d) “S” means the percentage of total input of heat derived from solid fuel.
