where:
GEOGWh is the total annual gross energy output in GWh
EGWh is the total annual gross electric output in GWh determined in par. (a)
UTEannual is the total annual useful thermal energy in mmBtu determined in par. (b)
3,413 is the factor to convert thermal energy in mmBtu to GWh
NR 446.18(5)(5) Determining annual allowable emissions. Except as provided in s. NR 446.185, owners and operators of a coal-fired EGU affected by this subchapter shall determine annual allowable emissions, as required to demonstrate compliance, according to the following procedures: NR 446.18(5)(a)(a) When achieving compliance on a unit-by-unit basis, use one of the following equations as applicable: where:
Hgallowable is the mass of mercury emissions allowed for the compliance year
Fuel Hgannual is the mass of mercury in fuel combusted during the compliance year as determined in sub. (3) (b).
Hg CE is the applicable requirement for percent mercury emission reduction divided by 100.
where:
Hgallowable is the mass of mercury emissions in pounds allowed for the compliance year
GEOGWh is the annual gross energy output during the compliance year as determined in sub. (4) (c)
ELoutput is the applicable mercury output based emission limitation in pounds per GWh
where:
Pallowable is the mass of NOx or SO2 emissions allowed for the compliance year
HIi is the amount of fuel, in mmBtu combusted each hour i, during the compliance year
h is the number of hours fuel is combusted during the compliance year
ELp is the applicable emission limitation of s. NR 446.14 (1) for NOx or SO2
