NR 405.07(4)(a)8.8. Municipal incinerators capable of charging more than 250 tons of refuse per day. NR 405.07(4)(a)20.20. Chemical process plants. The chemical processing plants category 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). NR 405.07(4)(a)21.21. Fossil fuel boilers (or combination thereof) totaling more than 250 million British thermal units per hour heat input. NR 405.07(4)(a)22.22. Petroleum storage and transfer units with a total storage capacity exceeding 300,000 barrels. NR 405.07(4)(a)26.26. Fossil fuel fired steam electric plants of more than 250 million British thermal units per hour heat input. NR 405.07(4)(a)27.27. Any other stationary source category which, as of August 7, 1980, is being regulated under section 111 or 112 of the Act (42 USC 7411 or 7412). NR 405.07(4)(b)(b) The major source or major modification is a portable stationary source which has previously received a permit under requirements in ss. NR 405.08 to 405.16 and all of the following conditions are met: NR 405.07(4)(b)1.1. The source proposes to relocate and emissions of the source at the new location would be temporary. NR 405.07(4)(b)2.2. The emissions from the source would not exceed its allowable emissions. NR 405.07(4)(b)3.3. The emissions from the source would impact no Class I area and no area where an applicable increment is known to be violated. NR 405.07(4)(b)4.4. Reasonable notice is given to the department prior to the relocation identifying the proposed new location and the probable duration of operation at the new location. Such notice shall be given to the department not less than 30 days in advance of the proposed relocation unless a different time duration is previously approved by the department. NR 405.07(5)(5) The requirements of ss. NR 405.08 to 405.16 do not apply to a major stationary source or major modification with respect to a particular air contaminant if the owner or operator demonstrates that, as to that air contaminant, the source or modification is located in an area designed as nonattainment under section 107 of the Act (42 USC 7407). NR 405.07(6)(6) The requirements contained in ss. NR 405.09, 405.11, and 405.13 do not apply to a proposed major stationary source or major modification with respect to a particular air contaminant, if the allowable emissions of that air contaminant from a new source, or the net emissions increase of that air contaminant from a modification, would be temporary and impact no Class I area and no area where an applicable increment is known to be violated. NR 405.07(7)(7) The requirements contained in ss. NR 405.09, 405.11, and 405.13 as they relate to any maximum allowable increase for a Class II area do not apply to a modification of a major stationary source that was in existence on March 1, 1978, if the net increase in allowable emissions of each air contaminant from the modification after the application of best available control technology would be less than 50 tons per year. NR 405.07(8)(8) The department may exempt a proposed major stationary source or major modification from the requirements of s. NR 405.11 with respect to monitoring for a particular air contaminant if one of the following applies:
