(1) No person may cause, allow or permit sulfur dioxide to be emitted to the ambient air within the geographical boundaries of the city of Madison, Dane county, from any direct source on which construction or modification was commenced prior to November 1, 1979 in amounts greater than:
(a)
Any fossil fuel fired steam generating boiler rated at more than 25 million Btu
heat input per hour but less than 100 million Btu heat input per hour firing
solid fossil fuel or solid fossil fuel in combination with solid, liquid or
gaseous fuels: 7.0 pounds of sulfur dioxide per million Btu heat
input.
(b) Any fossil fuel fired
steam generating boiler rated at equal to or greater than 100 million Btu heat

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.
