Any electrical utility boiler: 4.25 pounds of sulfur dioxide per million Btu heat input.2. Any other boiler: a. Height above ground of emission point of less than 180 feet: 2.5 pounds of sulfur dioxide per million Btu heat input.b. Height above ground of emission point of 180 to 220 feet: X pounds of sulfur dioxide per million Btu heat input, where X is determined by the following equation: X = 10[0.0089 (Emission Point Height)-1.18]
c. Height above ground of emission point of more than 220 feet: 5.8 pounds of sulfur dioxide per million Btu heat input.(c) Any fossil fuel fired steam generating boiler rated at more than 25 million Btu heat input per hour firing liquid fossil fuel or liquid fossil fuel in combination with liquid or gaseous fuels:1. Distillate fuel oil: that occurring from firing a distillate fuel oil with a sulfur content equal to or less than 0.50 % by weight.2. Residual fuel oil: that occurring from firing a residual fuel oil with a sulfur content equal to or less than 1.1 % sulfur by weight.(2) All boilers to which sub. (1) applies shall achieve final compliance and so certify to the department on or before December 31, 1982. Wis. Admin. Code Department of Natural Resources NR 418.03
