(c) If a stationary boiler or stationary combustion turbine, that under
par. (a), is not a CAIR NO
x unit, begins to combust fossil fuel or to serve a generator with a nameplate capacity of more than 25 MWe producing electricity for sale, the unit shall become a CAIR NO
x unit on the first date on which it both combusts fossil fuel and serves the generator as provided in
par. (a).
NR 432.01(1)(d)
(d) If a unit qualifies as a cogeneration unit during the 12-month period starting on the date the unit first produces electricity and meets the requirements of
par. (b) 1. for at least one calendar year, but subsequently no longer meets the requirements, the unit shall become a CAIR NO

NR 432.01(2)
(2) Purpose. This chapter is adopted under s.
285.11, Stats., to allocate the NO
x allowances for the CAIR NO
x annual trading program and the CAIR NO
x ozone season trading program. The purpose of this chapter is to implement only those parts of the CAIR NO
x annual trading program and the CAIR NO
x ozone season trading program that is administered by the EPA under the federal implementation plan for the CAIR relating to the allocation of CAIR NO
x allowances found in
40 CFR part 97, Subparts EE and EEEE.
NR 432.01(3)
(3) Petition for applicability. An owner or operator of any unit may petition the administrator of the EPA at any time for a determination concerning the applicability, under
sub. (1), of the CAIR NO
x trading program and the CAIR NO
x ozone season trading program to the unit pursuant to
40 CFR 97.104 (c) and
40 CFR 97.304.
NR 432.01 Note
Note: This chapter modifies the schedule and methodology for allocating CAIR nitrogen oxides (NO
x) allowances that are set forth in the federal implementation plan. This chapter does not have a provision allowing any fossil fuel-fired unit that is not a CAIR NO
x unit to "opt-in" to a CAIR NO
x trading program. This chapter is not intended to modify in any other way the implementation or administration in Wisconsin of the federal implementation plan for CAIR. The CAIR NO
x federal implementation plan is published in
40 CFR part 97.
