NR 405.02(9)(9) “Commence” as applied to construction of a major stationary 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 405.02(9)(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 405.02(9)(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 405.02(10)(10) “Complete” means, in reference to an application for a permit, that the application contains all the information necessary 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 405.02(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 405.02(11c)(11c) “Continuous emissions monitoring system” or “CEMS” means all of the equipment that may be required to meet the data acquisition and availability requirements of this chapter, to sample, condition if applicable, analyze and provide a record of emissions on a continuous basis. NR 405.02(11e)(11e) “Continuous emissions rate monitoring system” or “CERMS” means the total equipment required for the determination and recording of the air contaminant mass emissions rate in terms of mass per unit of time. NR 405.02(11j)(11j) “Continuous parameter monitoring system” or “CPMS” means all of the equipment necessary to meet the data acquisition and data availability requirements of this chapter to monitor process and control device operational parameters, and to record average operational parameter values on a continuous basis. NR 405.02 NoteNote: Process and control device operational parameters include secondary voltages and electric currents, and other information, such as gas flow rate, O2 or CO2 concentrations.
NR 405.02(11m)(11m) “Electric utility steam generating unit” means any steam electric generating unit that is constructed for the purpose of supplying more than one-third of its potential electric output capacity and more than 25 MW electrical output to any utility power distribution system for sale. Any steam supplied to a steam distribution system for the purpose of providing steam to a steam-electric generator that would produce electrical energy for sale is also considered in determining the electrical energy output capacity of the affected facility. NR 405.02(12)(12) “Emissions unit” means any part of a stationary source which emits or would have the potential to emit any regulated NSR air contaminant and includes an electric utility steam generating unit. For purposes of this chapter, there are 2 types of emissions units described as follows: NR 405.02(12)(a)(a) A new emissions unit is any emissions unit which is or will be newly constructed and which has existed for less than 2 years from the date the emissions unit first operated. NR 405.02(12)(b)(b) An existing emissions unit is any emissions unit that does not meet the requirements in par. (a). Notwithstanding par. (a), a replacement unit, as defined in sub. (25k), is an existing emissions unit. NR 405.02(13)(13) “Federal land manager” means, with respect to any lands in the United States, the secretary of the department with authority over such lands. NR 405.02(15)(15) “Fugitive emissions” means those emissions which could not reasonably pass through a stack, chimney, vent, or other functionally equivalent opening. NR 405.02(16)(16) “High terrain” means any area having an elevation 900 feet or more above the base of the stack of a source. NR 405.02(17)(17) “Indian governing body” means the governing body of any tribe, band, or group of Indians subject to the jurisdiction of the United States and recognized by the United States as possessing power of self-government. NR 405.02(18)(18) “Indian reservation” means any federally recognized reservation established by treaty, agreement, executive order, or act of congress. NR 405.02(19)(19) “Innovative control technology” means any system of air pollution control that has not been adequately demonstrated in practice, but would have a substantial likelihood of achieving greater continuous emissions reduction than any control system in current practice or of achieving at least comparable reductions at lower cost in terms of energy, economics, or nonair quality environmental impacts. NR 405.02(20)(20) “Low terrain” means any area other than high terrain. NR 405.02(21)(21) “Major modification” means any physical change in or change in the method of operation of a major stationary source that would result in a significant emissions increase of a regulated NSR air contaminant and a significant net emissions increase of that air contaminant from the major stationary source. NR 405.02(21)(a)(a) Any significant emissions increase from any emissions units or net emissions increase at a major stationary source that is significant for volatile organic compounds or nitrogen oxides shall be considered significant for ozone. NR 405.02(21)(b)(b) A physical change or change in the method of operation does not include any of the following: NR 405.02(21)(b)2.2. Use of an alternative fuel or raw material by reason of any order under sections 2 (a) and (b) of the Federal Energy Supply and Environmental Coordination Act of 1974 (15 USC 791 to 798) or by reason of a natural gas curtailment plan pursuant to the Federal Power Act (16 USC 791a to 828c). NR 405.02(21)(b)4.4. Use of an alternative fuel at a steam generating unit to the extent that the fuel is generated from municipal solid waste. NR 405.02(21)(b)5.5. Use of an alternative fuel or raw material by a stationary source when one of the following applies:
