If the purpose of construction is not known, it is presumed to be consistent with the actual operation from 1985 to 1987. However, if in any 3 calendar year period after November 15, 1990, the unit sells to a utility power distribution system an annual average of more than one-third of its potential electrical output capacity and more than 219,000 MWe-hrs actual electric output on a gross basis, that unit is an affected unit, subject to the requirements of this chapter and the acid rain program.

NR 409.01(1)(b)5.a.
a. Has, as of November 15, 1990, one or more qualifying power purchase commitments to sell at least 15% of its total planned net output capacity; and
NR 409.01(1)(b)5.b.
b. Consists of one or more units designated by the owner or operator with total installed net output capacity not exceeding 130% of the total planned net output capacity. If the emissions rates of the units are not the same, the administrator may exercise discretion to designate which units are exempt.

b. Consists of one or more units designated by the owner or operator with total installed net output capacity not exceeding 130% of its total planned net output capacity. If the emissions rates of the units are not the same, the administrator may exercise discretion to designate which units are exempt.
NR 409.01(1)(b)7.
7. A solid waste incinerator, if more than 80%, on a Btu basis, of the annual fuel consumed at the incinerator is other than fossil fuels. For a solid waste incinerator which began operation before January 1, 1985, the average annual fuel consumption of non-fossil fuels for calendar years 1985 to 1987 shall be greater than 80% for an incinerator to be exempt. For a solid waste incinerator which began operation after January 1, 1985, the average annual fuel consumption of non-fossil fuels for the first 3 years of operation shall be greater than 80% for an incinerator to be exempt. If, during any 3 calendar year period after November 15, 1990, the incinerator consumes 20% or more of the total heat input, expressed on a Btu basis, as fossil fuel, the incinerator is an affected source under this chapter and the acid rain program.
NR 409.01(1)(c)
(c) For a determination of applicability, a certifying official of an owner or operator of any unit may petition the administrator under
40 CFR 72.6 (c). The administrator's determination of applicability shall be binding upon the department, unless the petition is found to have contained significant errors or omissions.
NR 409.01(2)
(2) Purpose. The purpose of this chapter is to establish certain general provisions and the acid rain portion of the operation permit program requirements for affected sources and affected units under the acid rain program, pursuant to title IV of the clean air act (
42 USC 7651 to
7651o),
40 CFR part 72 and s.
285.65 (12), Stats.
NR 409.01(3)
(3) Scope. The regulations under this chapter set forth certain generally applicable provisions under the acid rain program. The regulations also set forth requirements for obtaining and revising the acid rain portion of an operation permit issued by the department. The requirements under this chapter supplement, and in some cases modify, the requirements under
chs. NR 406 and
407 as such requirements apply to affected sources under the acid rain program.
