1. Each fossil fuel fired steam generating boiler rated at less than or equal to 100 million Btu per hour: 2.54 pounds of sulfur dioxide per million Btu heat input.

2. Each fossil fuel fired steam generating boiler rated at greater than 100 million Btu per hour with the emission point at a height above ground of not less than 211 feet: 3.20 pounds of sulfur dioxide per million Btu heat input.

3. Each fossil fuel fired steam generating boiler rated at greater than 100 million Btu per hour with the emission point at a height above ground of less than 211 feet: 0.50 pounds of sulfur dioxide per million Btu heat input.

(e) Any neutral sulfite semichemical pulp and paper mill shall comply with the following emission limitations:
1. Steam generating boilers with the emission point at a height above ground of not less than 212 feet: maximum emission from any stack of 3.88 pounds of sulfur dioxide per million Btu heat input when the boilers are fired at or below 158 million Btu per hour; maximum emission from any stack of 3.15 pounds of sulfur dioxide per million Btu heat input when the boilers are fired at a rate greater than 158 million Btu per hour and less than 309 million Btu per hour; and maximum emission from any stack of 2.87 pounds of sulfur dioxide per million Btu heat input when the boilers are fired at a rate of 309 million Btu per hour or greater.

2. Steam generating boilers with the emission point at a height above ground of less than 212 feet: maximum emission from any stack of 0.50 pounds of sulfur dioxide per million Btu heat input.

(f) Any calcium based sulfite pulp and paper mill and any calcium based lignin chemical processing facility shall comply with the following emission limitations:
1. Fossil fuel fired steam generating boilers: maximum emission from any stack of 2.10 pounds of sulfur dioxide per million Btu heat input when the boilers are fired above 360 million Btu per hour; and maximum emission from any stack of 2.31 pounds of sulfur dioxide per million Btu heat input when the boilers are fired at or below 360 million Btu per hour.

2. All Jensen acid towers: a total of 9.21 pounds of sulfur dioxide per hour from all towers.

(3) When a source is subject to the emission limitations of sub. (1), the owner or operator shall achieve final compliance with the applicable emission limitations and so certify to the department on or before November 9, 1985.

(4) For purposes of determining compliance with the emission limitations of this section, the owner or operator of a source described in sub. (1) shall use methods which include, but are not limited to, the following:

(a) Any facility which has solid fossil fuel fired or spent sulfite liquor fired steam generating boilers with a combined rated heat input capacity of greater than 500 million Btu per hour shall install, calibrate, maintain and operate a continuous emission monitor, utilizing equipment and procedures reviewed and approved by the department.

(b) Any facility which has solid fossil fuel fired steam generating boilers with a combined rated heat input capacity of less than 500 million Btu per hour shall collect and analyze a daily, as-fired sample of fuel used, utilizing equipment and procedures reviewed and approved by the department.

(c) Any facility which has liquid fossil fuel fired steam generating boilers shall collect and analyze a daily, as-fired sample of fuel used, utilizing equipment and procedures reviewed and approved by the department.

(d) Emissions from all other sources shall be determined by annual stack emissions testing or by such other appropriate methods reviewed and approved by the department.
