Only the heat input supplied to the affected facility from the combustion of coal and oil is counted under this subsection. No credit is provided for the heat input to the affected facility from the combustion of natural gas, wood, municipal-type solid waste, or other fuels or heat input to the affected facility from exhaust gases from another source, such as gas turbines, internal combustion engines, kilns, etc.
NR 440.205(3)(b)(b) On and after the date on which the performance test is completed or required to be completed under s. NR 440.08, whichever comes first, no owner or operator of an affected facility that combusts coal refuse alone in a fluidized bed combustion steam generating unit may cause to be discharged into the atmosphere any gases that contain sulfur dioxide in excess of 20% of the potential sulfur dioxide emission rate (80% reduction) and that contain sulfur dioxide in excess of 520 ng/J (1.2 lb/million Btu) heat input. If coal or oil is fired with coal refuse, the affected facility is subject to par. (a) or (d), as applicable.
NR 440.205(3)(c)(c) On and after the date on which the performance test is completed or is required to be completed under s. NR 440.08, whichever comes first, no owner or operator of an affected facility that combusts coal or oil, either alone or in combination with any other fuel, and that uses an emerging technology for the control of sulfur dioxide emissions, may cause to be discharged into the atmosphere any gases that contain sulfur dioxide in excess of 50% of the potential sulfur dioxide emission rate (50% reduction) and that contain sulfur dioxide in excess of the emission limit determined according to the following formula:
where:
Es is the sulfur dioxide emission limit, expressed in ng/J or lb/million Btu heat input
Kc is 260 ng/J (or 0.60 lb/million Btu)
Kd is 170 ng/J (or 0.40 lb/million Btu)
Hc is the heat input from the combustion of coal, in J (million Btu)
Hd is the heat input from the combustion of oil, in J (million Btu)
Only the heat input supplied to the affected facility from the combustion of coal and oil is counted under this subsection. No credit is provided for the heat input to the affected facility from the combustion of natural gas, wood, municipal-type solid waste, or other fuels, or from the heat input to the affected facility from exhaust gases from another source, such as gas turbines, internal combustion engines, kilns, etc.
NR 440.205(3)(d)(d) On and after the date on which the performance test is completed or required to be completed under s. NR 440.08, whichever comes first, no owner or operator of an affected facility listed in subd. 1., 2. or 3. may cause to be discharged into the atmosphere any gases that contain sulfur dioxide in excess of 520 ng/J (1.2 lb/million Btu) heat input if the affected facility combusts coal, or 215 ng/J (0.50 lb/million Btu) heat input if the affected facility combusts oil other than very low sulfur oil. Percent reduction requirements are not applicable to affected facilities under this paragraph.
NR 440.205(3)(d)1.1. Affected facilities that have an annual capacity factor for coal and oil of 30% (0.30) or less and are subject to a federally enforceable permit limiting the operation of the affected facility to an annual capacity factor for coal and oil to 30% (0.30) or less;
NR 440.205(3)(d)2.2. Affected facilities located in a noncontinental area; or
NR 440.205(3)(d)3.3. Affected facilities combusting coal or oil, alone or in combination with any other fuel, in a duct burner as part of a combined cycle system where 30% (0.30) or less of the heat input to the steam generating unit is from combustion of coal and oil in the duct burner and 70% (0.70) or more of the heat input to the steam generating unit is from the exhaust gases entering the duct burner.
NR 440.205(3)(e)(e) Except as provided in par. (f), compliance with the emission limits, fuel oil sulfur limits, and/or percent reduction requirements under this subsection are determined on a 30-day rolling average basis.
NR 440.205(3)(f)(f) Except as provided for in par. (j) 2., compliance with the emission limits or fuel oil sulfur limits under this subsection is determined on a 24-hour average basis for affected facilities that:
NR 440.205(3)(f)1.1. Have a federally enforceable permit limiting the annual capacity factor for oil to 10% or less;
NR 440.205(3)(f)2.2. Combust only very low sulfur oil; and
NR 440.205(3)(f)3.3. Do not combust any other fuel.
NR 440.205(3)(g)(g) Except as provided in par. (i), the sulfur dioxide emission limits and percent reduction requirements under this subsection apply at all times, including periods of startup, shutdown, and malfunction.
NR 440.205(3)(h)(h) Reductions in the potential sulfur dioxide emission rate through fuel pretreatment are not credited toward the percent reduction requirement under par. (c) unless:
NR 440.205(3)(h)1.1. Fuel pretreatment results in a 50% or greater reduction in potential sulfur dioxide emissions and
NR 440.205(3)(h)2.2. Emissions from the pretreated fuel (without combustion or post combustion sulfur dioxide control) are equal to or less than the emission limits specified in par. (c).
NR 440.205(3)(i)(i) An affected facility subject to par. (a), (b), or (c) may combust very low sulfur oil or natural gas when the sulfur dioxide control system is not being operated because of malfunction or maintenance of the sulfur dioxide control system.
NR 440.205(3)(j)(j) Percent reduction requirements are not applicable to affected facilities combusting only very low sulfur oil. The owner or operator of an affected facility combusting very low sulfur oil shall demonstrate that the oil meets the definition of very low sulfur oil by:
NR 440.205(3)(j)1.1. Following the performance testing procedures as described in sub. (6) (c) or (d), and following the monitoring procedures as described in sub. (8) (a) or (b) to determine sulfur dioxide emission rate or fuel oil sulfur content; or
