NR 405.02(22)(a)1.1. Any of the following stationary sources of air contaminants which emits, or has the potential to emit, 100 tons per year or more of any air contaminant subject to regulation under the Act: Fossil fuel fired steam electric plants of more than 250 million British thermal units per hour heat input, coal cleaning plants (with thermal dryers), kraft pulp mills, portland cement plants, primary zinc smelters, iron and steel mill plants, primary aluminum ore reduction plants, primary copper smelters, municipal incinerators capable of charging more than 250 tons of refuse per day, hydrofluoric, sulfuric, and nitric acid plants, petroleum refineries, lime plants, phosphate rock processing plants, coke oven batteries, sulfur recovery plants, carbon black plants (furnace process), primary lead smelters, fuel conversion plants, sintering plants, secondary metal production plants, chemical process plants (which does not include ethanol production facilities that produce ethanol by natural fermentation, as described by the 6-digit code of 312140 or 325193 in the North American Industry Classification System United States, 2007, incorporated by reference in s. NR 484.05 (17)), fossil fuel boilers (or combinations thereof) totaling more than 250 million British thermal units per hour heat input, petroleum storage and transfer units with a total storage capacity exceeding 300,000 barrels, taconite ore processing plants, glass fiber processing plants, and charcoal production plants. NR 405.02(22)(a)2.2. Notwithstanding the stationary source size specified in subd. 1., any stationary source which emits, or has the potential to emit, 250 tons per year or more of any air contaminant subject to regulation under the act. NR 405.02(22)(a)3.3. Any physical change that would occur at a stationary source not otherwise qualifying under this subsection as a major stationary source, if the change would constitute a major stationary source by itself. NR 405.02(22)(b)(b) A major source that is major for volatile organic compounds or nitrogen oxides shall be considered major for ozone. NR 405.02(22)(d)(d) Mobile source emissions indirectly caused by a source which attracts mobile source activity may not be considered in determining whether the source is a major stationary source for the purposes of this chapter. NR 405.02(22m)(a)(a) “Minor source baseline date” means the earliest date after the trigger date on which the owner or operator of a major stationary source or a major modification subject to 40 CFR 52.21 or to regulations approved pursuant to 40 CFR 51.166 submits a complete application under the relevant regulations. The trigger date is: NR 405.02(22m)(b)(b) The minor source baseline date is established for each air contaminant for which increments or other equivalent measures have been established if: NR 405.02(22m)(b)1.1. The area in which the proposed source or modification would construct is designated as attainment or unclassifiable under section 107 (d) (1) (A) (ii) or (iii) of the Act (42 USC 7407(d)(1) (A)(ii) or (iii)) for the air contaminant on the date of its complete application under 40 CFR 52.21 or under regulations approved pursuant to 40 CFR 51.166. NR 405.02(22m)(b)2.2. In the case of a major stationary source, the air contaminant would be emitted in significant amounts or, in the case of a major modification, there would be a significant net emissions increase of the air contaminant. NR 405.02(23)(23) “Necessary preconstruction approvals or permits” means those permits or approvals required under chs. NR 400 to 499. NR 405.02(24)(a)(a) “Net emissions increase” means, with respect to any regulated NSR air contaminant emitted by a major stationary source, the amount by which the difference between the sum of emission increases and the sum of emission decreases of the following exceeds zero: NR 405.02(24)(a)1.1. The increase in emissions from a particular physical change or change in the method of operation at a stationary source as calculated pursuant to the methods contained in s. NR 405.025. NR 405.02(24)(a)2.2. Any other increases and decreases in actual emissions at the major stationary source that are contemporaneous with the particular change and are otherwise creditable. Baseline actual emissions for calculating increases and decreases under this subdivision shall be determined as provided in sub. (2m), except that sub. (2m) (a) 3. and (b) 4. do not apply. NR 405.02(24)(b)(b) An increase or decrease in actual emissions is contemporaneous with the increase from the particular change only if it occurs between the following: NR 405.02(24)(b)1.1. The date 5 years before construction on the particular change commences. NR 405.02(24)(c)(c) An increase or decrease in actual emissions is creditable only if all of the following are satisfied: NR 405.02(24)(c)2.2. The department has not relied on it in issuing a permit for the source under this chapter and the permit is in effect when the increase in actual emissions from the particular change occurs. NR 405.02(24)(d)(d) An increase or decrease in actual emissions of sulfur dioxide, nitrogen oxides or particulate matter measured as PM10 which occurs before the applicable minor source baseline date is creditable only if it is required to be considered in calculating the amount of maximum allowable increases remaining available.
