(7) "Commenced" means, with respect to the definition of "new source" in sub. (18), that an owner or operator has undertaken a continuous program of construction or modification or that an owner or operator has entered into a contractual obligation to undertake and complete, within a reasonable time, a continuous program of construction or modification.

(8) "Construction" means fabrication, erection or installation of an affected facility.

(9) "Continuous monitoring system" means the total equipment, required under the emission monitoring subsections in applicable sections of this chapter, used to sample and condition (if applicable), to analyze, and to provide a permanent record of emissions or process parameters.

(10) "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.

(11) "Equivalent method" means any method of sampling and analyzing for an air pollutant which has been demonstrated to the administrator's satisfaction to have a consistent and quantitatively known relationship to the reference method, under specified conditions.

(12) "Excess emissions and monitoring system performance report" means a report that must be submitted periodically by a source in order to provide data on its compliance with stated emission limits and operating parameters, and on the performance of its monitoring systems.

(13) "Existing facility" means, with reference to a stationary source, any apparatus of the type for which a standard is promulgated in this chapter, and the construction or modification of which was commenced before the applicability date of that standard; or any apparatus which could be altered in such a way as to be of that type.

(13m) "Existing unit", for purposes of s. NR 440.14(10), has the meaning given in s. NR 409.02(39).

(14) "Isokinetic sampling" means sampling in which the linear velocity of the gas entering the sampling nozzle is equal to that of the undisturbed gas stream at the sample point.

(15) "Malfunction" means any sudden, infrequent and not reasonably preventable failure of air pollution control equipment, process equipment or a process to operate in a normal or usual manner. Failures that are caused in part by poor maintenance or careless operation are not malfunctions.

(15m) "Method X," where "X" is a number or a number followed by a letter, means the specified method contained in Appendix A of 40 CFR part 60, incorporated by reference in s. NR 440.17.

(16) "Modification" means any physical change in, or change in the method of operation of, an existing facility which increases the amount of any air pollutant (to which a standard applies) emitted into the atmosphere by that facility or which results in the emission of any air pollutant (to which a standard applies) into the atmosphere not previously emitted.

(17) "Monitoring device" means the total equipment, required under the monitoring of operations subsections in applicable sections of this chapter, used to measure and, if applicable, record process parameters.

(18) "New source" means any stationary source, the construction or modification of which is commenced after the applicability date of a standard of performance in this chapter which will be applicable to the source.

(18m) "New unit", for purposes s. NR 440.14(10), has the meaning given in s. NR 409.02(49).

(19) "Nitrogen oxides" means all oxides of nitrogen except nitrous oxide, as measured by test methods set forth in this chapter or incorporated by reference in this chapter by s. NR 440.17.

(20) "One-hour period" means any 60-minute period commencing on the hour.

(22) "Owner or operator" means any person who owns, leases, operates, controls or supervises an affected facility or a stationary source of which an affected facility is a part.

(23) "Particulate matter" means any finely divided solid or liquid material, other than uncombined water, as measured by the reference methods specified under each applicable section of this chapter, or an equivalent or alternative method.

(25) "Proportional sampling" means sampling at a rate that produces a constant ratio of sampling rate to stack gas flow rate.

(25m) "Reactivation of a very clean coal fired electric utility steam generating unit" means any physical change or change in the method of operation associated with the commencement of commercial operations by a coal fired utility unit after a period of discontinued operation where the unit:

(a) Has not been in operation for the 2 year period prior to the enactment of the clean air act amendments of 1990, and the emissions from the unit continue to be carried in the department's emissions inventory at the time of enactment;

(b) Was equipped prior to shutdown with a continuous system of emissions control that achieves a removal efficiency for sulfur dioxide of no less than 85% and a removal efficiency for particulates of no less than 98%.

(c) Is equipped with low NO_x burners prior to the time of commencement of operations following reactivation; and

(d) Is otherwise in compliance with the requirements of the act.

(26) "Reference method" means any method of sampling and analyzing for an air pollutant as specified in the applicable section.

(26m) "Repowering" means replacement of an existing coal fired boiler with one of the following clean coal technologies: atmospheric or pressurized fluidized bed combustion, integrated gasification combined cycle, magnetohydrodynamics, direct and indirect coal fired turbines, integrated gasification fuel cells, or as determined by the administrator of the U.S. environmental protection agency, in consultation with the secretary of energy, a derivative of one or more of these technologies, and any other technology capable of controlling multiple combustion emissions simultaneously with improved boiler or generation efficiency and with significantly greater waste reduction relative to the performance of technology in widespread commercial use as of November 15, 1990. Repowering shall also include any oil, oil and gas or gas fired unit which has been awarded clean coal technology demonstration funding as of January 1, 1991 by the United States department of energy.

(27) "Run" means the net period of time during which an emission sample is collected. Unless otherwise specified, a run may be either intermittent or continuous within the limits of good engineering practice.

(28) "Shutdown" means the cessation of operation of an affected facility for any purpose.

(29) "Six-minute period" means any one of the 10 equal parts of a one-hour period.

(30) "Standard" means a standard of performance set out in ss. NR 440.19 to 440.74.

(33) "Startup" means the setting in operation of an affected facility for any purpose.
