NR 462.05(5)(d)(d) The weighted average emissions from the existing large solid fuel boilers participating in the emissions averaging option shall be in compliance with the limits in Table 1 of this chapter at all times following the compliance date specified in s. NR 462.01 (5). NR 462.05(5)(e)1.1. You shall use Equation 1 to demonstrate that the particulate matter or TSM, HCl and mercury emissions from all existing large solid fuel boilers participating in the emissions averaging option do not exceed the emission limits in Table 1 of this chapter. where:
AWER is the average weighted emission rate for particulate matter or TSM, HCl or mercury, in units of pounds per million Btu of heat input
Er is the emission rate, as calculated according to Table 5 of this chapter, or fuel analysis as calculated by the applicable equation in sub. (7) (d) for boiler, i, for particulate matter or TSM, HCl or mercury, in units of pounds per million Btu of heat input
Hm is the maximum rated heat input capacity of boiler, i, in units of million Btu per hour
n is the number of large solid fuel boilers participating in the emissions averaging option
NR 462.05(5)(e)2.2. If you are not capable of monitoring heat input, you may use Equation 2 as an alternative to using Equation 1 to demonstrate that the particulate matter or TSM, HCl and mercury emissions from all existing large solid fuel boilers participating in the emissions averaging option do not exceed the emission limits in Table 1 of this chapter. where:
AWER is the average weighted emission rate for particulate matter or TSM, HCl or mercury, in units of pounds per million Btu of heat input
Er is the emission rate, as calculated according to Table 5 of this chapter, or fuel analysis as calculated by the applicable equation in sub. (7) (d) for boiler, i, for particulate matter or TSM, HCl or mercury, in units of pounds per million Btu of heat input
Sm is the maximum steam generation by boiler, i, in units of pounds.
Cf is the conversion factor, calculated from the most recent compliance test, in units of million Btu of heat input per pounds of steam generated
n is the number of large solid fuel boilers participating in the emissions averaging option
NR 462.05(5)(f)(f) You shall demonstrate continuous compliance on a 12-month rolling average basis determined at the end of every month (12 times per year) according to subds. 1. and 2. The first 12-month rolling-average period begins on the compliance date specified in s. NR 462.01 (5). NR 462.05(5)(f)1.1. For each calendar month, you shall use Equation 3 to calculate the 12-month rolling average weighted emission rate using the actual heat capacity for each existing large solid fuel boiler participating in the emissions averaging option. where:
AWER is the 12-month rolling average weighted emission rate for particulate matter or TSM, HCl or mercury, in units of pounds per million Btu of heat input
Er is the emission rate, as calculated during the most recent compliance test according to Table 5 of this chapter, or fuel analysis as calculated by the applicable equation in sub. (7) (d) for boiler, i, for particulate matter or TSM, HCl or mercury, in units of pounds per million Btu of heat input
Hb is the average heat input for each calendar month of boiler, i, in units of million Btu
n is the number of large solid fuel boilers participating in the emissions averaging option
NR 462.05(5)(f)2.2. If you are not capable of monitoring heat input, you may use Equation 4 as an alternative to using Equation 3 to calculate the 12-month rolling average weighted emission rate using the actual steam generation from the large solid fuel boilers participating in the emissions averaging option. where:
AWER is the 12-month rolling average weighted emission rate for particulate matter or TSM, HCl or mercury, in units of pounds per million Btu of heat input
