NR 408.02
NR 408.02 Definitions. The definitions contained in ch.
NR 400 apply to the terms used in this chapter. In addition, the following definitions apply to the terms used in this chapter:
NR 408.02(1)
(1) “Actual emissions" means the actual rate of emissions of a regulated NSR air contaminant from an emissions unit, as determined in accordance with pars.
(a) to
(c), except that this definition does not apply for calculating whether a significant emissions increase has occurred, or for establishing a PAL under s.
NR 408.11. Instead, subs.
(2m) and
(28s) shall apply for those purposes.
NR 408.02(1)(a)
(a) Actual emissions as of a particular date shall equal the average rate, in tons per year, at which the unit actually emitted the pollutant during a consecutive 24-month period which precedes the particular date and which is representative of normal source operation. The department shall allow the use of a different time period upon a determination by the department that it is more representative of normal source operation. Actual emissions shall be calculated using the unit's actual operating hours, production rates and types of materials processed, stored or combusted during the selected time period.
NR 408.02(1)(b)
(b) For any emissions unit which has not begun normal operations on the particular date, actual emissions shall equal the potential to emit of the unit on that date.
NR 408.02(1)(c)
(c) The department may presume that source-specific allowable emissions for the unit are equivalent to the actual emissions of the unit.
NR 408.02(2)
(2) “Allowable emissions" means the emissions rate of a stationary source calculated using the maximum rated capacity of the source, or using federally enforceable limits which restrict the operating rate, or hours of operation or both, if the source is subject to such federally enforceable limits, and using the most stringent of the following:
NR 408.02(2)(c)
(c) Any applicable state implementation plan emissions limitation including a limitation with a future compliance date.
NR 408.02(2)(d)
(d) Any emissions rate specified as a federally enforceable permit condition, including a limitation with a future compliance date.
NR 408.02(2m)
(2m) “Baseline actual emissions" means the rate of emissions, in tons per year, of a regulated NSR air contaminant, as determined in accordance with pars.
(a) to
(d).
NR 408.02(2m)(a)
(a) For any existing electric utility steam generating unit, baseline actual emissions means the average rate, in tons per year, at which the unit actually emitted the air contaminant during any consecutive 24-month period selected by the owner or operator within the 5-year period immediately preceding when the owner or operator begins actual construction of the project. The department shall allow the use of a different time period upon a determination that it is more representative of normal source operation.
NR 408.02(2m)(a)1.
1. The average rate shall include fugitive emissions to the extent quantifiable, and emissions associated with startups, shutdowns and malfunctions.
NR 408.02(2m)(a)2.
2. The average rate shall be adjusted downward to exclude any emissions in excess of an emission limitation that was legally enforceable during the consecutive 24-month period.
NR 408.02(2m)(a)3.
3. For a regulated NSR air contaminant, when a project involves multiple emissions units, only one consecutive 24-month period may be used to determine the baseline actual emissions for the emissions units being changed. A different consecutive 24-month period may be used for each regulated NSR air contaminant.
NR 408.02(2m)(a)4.
4. The average rate may not be based on any consecutive 24-month period for which there is inadequate information for determining annual emissions, in tons per year, or for adjusting this amount if required by subd.
2. NR 408.02(2m)(b)
(b) For an existing emissions unit, other than an electric utility steam generating unit, baseline actual emissions means the average rate, in tons per year, at which the emissions unit actually emitted the air contaminant during any consecutive 24-month period selected by the owner or operator within the 10-year period immediately preceding either the date the owner or operator begins actual construction of the project, or, the date a complete permit application is received by the department for a permit required under ch.
NR 406 or for a permit revision under ch.
NR 407, whichever is earlier, except that the 10-year period may not include any period earlier than November 15, 1990.
NR 408.02(2m)(b)1.
1. The average rate shall include fugitive emissions to the extent quantifiable, and emissions associated with startups, shutdowns and malfunctions.
NR 408.02(2m)(b)2.
2. The average rate shall be adjusted downward to exclude any emissions in excess of an emission limitation that was legally enforceable during the consecutive 24-month period.
NR 408.02(2m)(b)3.
3. The average rate shall be adjusted downward to exclude any emissions that would have exceeded an emission limitation with which the major stationary source must currently comply, had the major stationary source been required to comply with the limitation during the consecutive 24-month period. However, if an emission limitation is part of a maximum achievable control technology standard that the administrator proposed or promulgated under
40 CFR part 63, the baseline actual emissions need only be adjusted if the state has taken credit for the emissions reductions in an attainment demonstration or maintenance plan consistent with the requirements of s.
NR 408.06 (9).
NR 408.02(2m)(b)4.
4. For a regulated NSR air contaminant, when a project involves multiple emissions units, only one consecutive 24-month period may be used to determine the baseline actual emissions for the emissions units being changed. A different consecutive 24-month period may be used for each regulated NSR air contaminant.
NR 408.02(2m)(b)5.
5. The average rate may not be based on any consecutive 24-month period for which there is inadequate information for determining annual emissions, in tons per year, or for adjusting this amount if required by subds.
2. and
3. NR 408.02(2m)(c)
(c) For a new emissions unit, the baseline actual emissions for purposes of determining the emissions increase that will result from the initial construction and operation of the unit shall equal zero; and thereafter, shall equal the unit's potential to emit.
NR 408.02(2m)(d)
(d) For a PAL for a stationary source, the baseline actual emissions shall be calculated for existing electric utility steam generating units in accordance with the procedures contained in par.
(a), for other existing emissions units in accordance with the procedures contained in par.
(b), and for a new emissions unit in accordance with the procedures contained in par.
(c).
NR 408.02(3)
(3) “Begin actual construction" means the initiation of physical on-site construction activities on an emissions unit which are of a permanent nature. Activities include, but are not limited to, installation of building supports and foundations, laying of underground pipe work and construction of permanent storage structures. With respect to a change in method of operation, this term refers to those on-site activities other than preparatory activities which mark the initiation of the change.
NR 408.02(4)
(4) “Best available control technology" or “BACT" means an emission limitation, including a visible emissions standard, based on the maximum degree of reduction for each regulated NSR air contaminant which would be emitted from any proposed major stationary source or major modification which the department, on a case-by-case basis, taking into account energy, environmental and economic impacts and other costs, determines is achievable for the source or modification through application of production processes or available methods, systems and techniques, including fuel cleaning or treatment or innovative fuel combustion techniques for control of the air contaminant. In no event may application of best available control technology result in emissions of any air contaminant which would exceed the emissions allowed by any applicable standard under chs.
NR 440 and
447 to
449 and subch.
IV of ch. NR 446 and
40 CFR parts 60 and
61. If the department determines that technological or economic limitations on the application of measurement methodology to a particular emissions unit would make the imposition of an emissions standard infeasible, a design, equipment, work practice, operational standard or combination thereof, may be prescribed instead to satisfy the requirement for the application of best available control technology. The standard shall, to the degree possible, set forth the emissions reduction achievable by implementation of a design, equipment, work practice or operation, and shall provide for compliance by means which achieve equivalent results.
NR 408.02(5)
(5) “Building, structure, facility or installation" means all of the activities which emit or may emit a regulated NSR air contaminant, which belong to the same industrial grouping, are located on one or more contiguous or adjacent properties, and are under the control of the same person, or persons under common control, except the activity of any vessel. Regulated NSR air contaminant sources shall be considered as part of the same industrial grouping if they are classified under the same 2-digit major group as described in the Standard Industrial Classification Manual, 1987, incorporated by reference in s.
NR 484.05.
NR 408.02(6)
(6) “Clean coal technology" means any technology, including technologies applied at the precombustion, combustion or post combustion stage, at a new or existing facility which will achieve significant reductions in emissions of sulfur dioxide or oxides of nitrogen associated with the utilization of coal in the generation of electricity or process steam which was not in widespread use as of November 15, 1990.
NR 408.02(7)
(7) “Clean coal technology demonstration project" means a project using funds appropriated under the heading `Department of Energy-Clean Coal Technology', up to a total amount of $2,500,000,000 for commercial demonstration of clean coal technology, or similar projects funded through appropriations for the U.S. environmental protection agency. The federal contribution for a qualifying project shall be at least 20% of the total cost of the demonstration project.
NR 408.02(8)
(8) “Commence" as applied to construction of a major source or major modification means that the owner or operator has all necessary preconstruction approvals or permits and has done one of the following:
NR 408.02(8)(a)
(a) Begun, or caused to begin, a continuous program of actual on- site construction of the source, to be completed within a reasonable time.
NR 408.02(8)(b)
(b) Entered into binding agreements or contractual obligations, which cannot be canceled or modified without substantial loss to the owner or operator, to undertake a program of actual construction of the source to be completed within a reasonable time.
NR 408.02(9)
(9) “Commence operation" means the initial startup of an emissions unit following completion of construction which results in the emission of an air contaminant for which the area is designated nonattainment. Any replacement unit that requires shakedown commences operation after a reasonable shakedown period, not to exceed 180 days.
NR 408.02(10)
(10) “Complete" means, in reference to an application for a permit, that the application contains all of the information necessary, as determined by the department, for processing the application. Designating an application complete for purposes of permit processing does not preclude the department from requesting or accepting any additional information.
NR 408.02(11)
(11) “Construction" means any physical change or change in the method of operation, including fabrication, erection, installation, demolition or modification of an emissions unit, which would result in a change in emissions.
NR 408.02(11e)
