NR 432.03(1)(b)
(b)
Periodic updates of baseline energy output for units with more than 5 years operating data. The department shall use the procedures in this paragraph for calculating the unit baseline energy output for each CAIR NO
x unit or CAIR renewable unit which has more than 5 years of operating data.
NR 432.03(1)(b)1.
1. In 2007, the department shall calculate the baseline energy output for each CAIR NO
x unit for 2009 to 2014 allowances using data for the years 2000 to 2004.
NR 432.03(1)(b)2.
2. On or before May 1, 2011, and on or before May 1 of every fifth year thereafter, the department shall calculate the baseline energy output for each CAIR NO
x unit and each CAIR renewable unit for the next 5 year allocation period using data from the 5 calendar year period beginning 9 years before the first year of the allocation period and ending 5 years before the first year of the allocation period.
NR 432.03 Note
Note: For example in 2021, unit baseline energy output for the calculation of allocation for 2025 to 2029 allowances will be calculated using data from the years 2016 to 2020. In 2026, unit baseline energy output for the calculation of the allocation for 2030 to 2034 will be calculated using data from 2021 to 2025.
NR 432.03(1)(c)
(c)
Baseline energy output for new units and units achieving 5 years of operating data for the first time. The department shall use the procedures in this paragraph for calculating the unit baseline energy output for each CAIR NO
x unit or CAIR renewable unit which have only 5 years of operating data.
NR 432.03(1)(c)1.
1. On or before May 1, 2011, the department shall calculate the baseline energy output for each CAIR NO
x unit and each CAIR renewable unit that commences operation on or after January 1, 2001 and that has operating data for the years 2006 to 2010 for 2015 to 2019 allowances using data for years 2006 to 2010.
NR 432.03(1)(c)2.
2. On or before May 1, 2012, and on or before May 1 of every year thereafter, the department shall calculate the unit baseline energy output for each CAIR NO
x unit and each CAIR renewable unit that has been operating for its first 5 consecutive years, using the first 5 years of operating data. Once the unit's baseline energy output has been established, the CAIR NO
x unit or CAIR renewable unit's baseline energy output shall be updated according to
par. (b).
NR 432.03 Note
Note: Starting in 2011, and every year thereafter, new units that commence operation on or after January 1, 2001 will have their unit baseline energy output calculated once the unit has 5 consecutive years of operating data. The 5 years of data do not have to be full years of data. Once the unit has 5 or more years of operating data, this unit is then incorporated into the state baselines calculated in s.
NR 432.03 (1m) and receives allocations from the main allocation pool under s.
NR 432.03 (2). These new units are incorporated into the main allocation pool on a yearly basis.
NR 432.03(1)(d)
(d) Baseline energy output for retired units. If a unit is retired in any year, the department shall calculate the baseline energy output according to
par. (b). If a unit only operates a portion of the year, the data for that portion shall constitute the unit's data for that year.
NR 432.03 Note
Note: The following is an example of how a retired unit's baseline energy output is calculated. A unit is retired in 2011. In 2011, unit baselines are updated using 2006 to 2010 annual data that will be used to calculate allocations for 2015 to 2019. For 2015 to 2019 allocations, the retired unit would receive all allowances based upon its unit baseline for 2006 to 2010 operating data even though it is no longer operating. In 2016, the next unit baseline updating year, the baseline for the unit would be determined using the most recent 5 years of data, 2011 to 2015. The 2016 updated baseline would be used to determine allocations for 2020 to 2025. If the unit had some operating data in 2011, it would receive minimal allowances in 2020 to 2025 based on the amount of electrical generation in 2011. The next unit update would occur in 2021 and would use 2015 to 2019 operating data. Since the unit would have no operating data for this time period it would no longer receive allocations. Under this procedure a unit that is retired in 2011 could receive allowances until 2025.
NR 432.03(1)(e)
(e) Data used for energy generation baselines. In performing the unit energy output baseline calculations under
pars. (a) to
(d), the department shall use data reported by the CAIR designated representative to EPA under
40 CFR part 97, Subpart HH and available from the EPA and data reported by the CAIR renewable representative to the department under
s. NR 432.07. If the required data is unavailable from the EPA, the department shall request the required data directly from the unit's CAIR designated representative. If the representative does not provide data within 30 days of the department's request, the department shall estimate the unit's baseline energy output using best available data.
NR 432.03(1m)(a)(a) Prior to 2011, the department shall establish the state baseline by summing the unit baselines calculated according to
sub. (1) for all CAIR NO
x units listed in Table 1.
NR 432.03(1m)(b)
(b) In 2011 and annually thereafter, the department shall calculate an annual state baseline by summing the unit baselines calculated according to
sub. (1) for all CAIR NO
x units and all CAIR renewable units.
NR 432.03 Note
Note: The state baseline is updated starting in 2011 annually to incorporate new units that have 5 years of operating data and have established a baseline under s.
NR 432.03 (a) and (b). Once a new unit has established a baseline, it is eligible for allowances from the main allocation pool.
NR 432.03(2)
(2) Allowance allocation for units with 5 or more years of operation data. NR 432.03(2)(a)(a) In 2007, and in 2011 and annually thereafter, the department shall allocate to all CAIR NO
x units and CAIR renewable units for which a unit baseline has been calculated under
sub. (1), a total amount of CAIR NO
x allowances equal to 93% of the tons of NO
x emissions in the trading budget for Wisconsin in
40 CFR 97.140.

x allowances available for new units in that year. The new unit set-aside in each year shall be equal to 7% of the amount of tons of NO
x emissions in the trading budget under
40 CFR 97.140 for Wisconsin.
NR 432.03(3)(b)
(b) The CAIR designated representative of a CAIR NO
x unit that commenced operation on or after January 1, 2001, may submit to the department a request to be allocated CAIR NO
x allowances under this subsection, starting with 2009 or the first calendar year after the calendar year in which the CAIR NO
x unit commences commercial operation, whichever is later, and until the first calendar year for which the unit is eligible for and is allocated CAIR NO
x allowances under

Compliance supplement pool. In addition to the CAIR NO
x allowances allocated under
s. NR 432.03, the department may allocate for calendar year 2009 only, additional allowances from the compliance supplement pool up to the amount designated by the EPA in
40 CFR 97.143 for Wisconsin for the purposes identified in this section.
NR 432.04(1)(a)(a) The department may allocate CAIR NO
x allowances from the compliance supplement pool to a CAIR NO
x unit if the unit's CAIR designated representative demonstrates that it achieved early reductions of NO
x emissions. To be eligible for early reduction credits, the unit's CAIR designated representative shall demonstrate all of the following:
NR 432.04(1)(a)1.
1. The CAIR NO
x unit's average annual NO
x emission rate for 2007 or 2008 is less than 0.25 lb/mmBtu based on heat input.
NR 432.04(1)(a)2.
2. If the unit is included in a NO
x averaging plan under
s. NR 409.065 (7) for 2007 or 2008, the NO
x averaging plan has an actual weighted average NO
x emission rate for 2007 or 2008 equal to or less than the actual weighted average NO
x emission rate for preceding year.
NR 432.04(1)(a)3.
3. Compared to the preceding year, the CAIR NO
x unit achieves NO
x emission reductions in both 2007 and 2008.
NR 432.04(1)(b)
(b) The CAIR designated representative of the unit may request early reduction credits, and allocation of CAIR NO
x allowances from the compliance supplement pool for early reduction credits, in accordance with the following:
NR 432.04(1)(b)1.
1. The CAIR designated representative shall monitor and report the NO
x emissions rate and the heat input of the unit based on monitoring data required in accordance with
40 CFR part 97, Subpart HH in each calendar year for which early reduction credits are requested.
NR 432.04(1)(b)2.
2. The CAIR designated representative of a CAIR NO
x unit shall submit to the department by July 31, 2009 a request for allocation of an amount of CAIR NO
x allowances from the compliance supplement pool. The request may not exceed the value determined using equation 6:
Equation 6
where:
ER is the amount of CAIR NOx allowances a CAIR designated representative may request based on early emission reductions in 2007 and 2008 rounded to the nearest ton
HI2007 is the total heat input to the unit for the calendar year 2007 in mmBtu
HI2008 is the total heat input to the unit for the calendar year 2008 in mmBtu
2000 is a conversion factor in lb/ton
DEM2007 and DEM
2008 are the differences between the actual emission rates for 2007 and 2008 respectively and the target emission rate for early reductions in lbs NOx/mmBtu. If the unit's actual average emission rate for the calendar year is greater than 0.25, DEMyear is equal to 0. If the unit's actual average emission rate for the calendar year is equal to or less than 0.25, then DEMyear is calculated using equation 7
