NR 460.02(24y)(f)(f) Feasibility and cost of controlling processes that share common equipment, such as product recovery devices. NR 460.02(25)(25) “New MACT source” means any affected source the construction or reconstruction of which is commenced after the administrator first publishes in the federal register a proposed emission standard that would apply to the source under 40 CFR part 63. NR 460.02(26)(26) “One-hour period”, unless otherwise defined in an applicable subpart of 40 CFR part 63 or in an applicable provision of chs. NR 460 to 469, means any 60-minute period commencing on the hour. NR 460.02(27)(27) “Opacity” means the degree to which emissions reduce the transmission of light and obscure the view of an object in the background. For continuous opacity monitoring systems, opacity means the fraction of incident light that is attenuated by an optical medium. NR 460.02(28)(28) “Part 70 permit” means any permit issued, renewed or revised under ch. NR 407 for a part 70 source as defined in s. NR 407.02. NR 460.02(29)(29) “Performance audit” means a procedure to analyze blind samples, the content of which is known by the department, simultaneously with the analysis of performance test samples in order to provide a measure of test data quality. NR 460.02(30)(30) “Performance evaluation” means the conduct of relative accuracy testing, calibration error testing, and other measurements used in validating the continuous monitoring system data. NR 460.02(31)(31) “Performance test” means the collection of data resulting from the execution of a test method, usually 3 emission test runs, used to demonstrate compliance with a relevant emission standard as specified in the performance test section of the relevant standard. NR 460.02(31g)(31g) “Pollution prevention” has the meaning given for “source reduction” in the Pollution Prevention Act (42 USC 13102 (5)). The definition is as follows: NR 460.02(31g)(a)(a) “Source reduction” is any practice that does both of the following: NR 460.02(31g)(a)1.1. Reduces the amount of any hazardous substance, pollutant or contaminant entering any waste stream or otherwise released into the environment, including fugitive emissions, prior to recycling, treatment or disposal. NR 460.02(31g)(a)2.2. Reduces the hazards to public health and the environment associated with the release of the substances, pollutants or contaminants. NR 460.02(31g)(b)(b) The term “source reduction” includes equipment or technology modifications, process or procedure modifications, reformulation or redesign of products, substitution of raw materials, and improvements in housekeeping, maintenance, training or inventory control. NR 460.02(31g)(c)(c) The term “source reduction” does not include any practice that alters the physical, chemical or biological characteristics or the volume of a hazardous substance, pollutant or contaminant through a process or activity which itself is not integral to and necessary for the production of a product or the providing of a service. NR 460.02(32)(32) “Reconstruction”, unless otherwise defined in a relevant standard, means the replacement of components of an affected or a previously nonaffected source to such an extent that all of the following apply: NR 460.02(32)(a)(a) The fixed capital cost of the new components exceeds 50% of the fixed capital cost that would be required to construct a comparable new MACT source. NR 460.02(32)(b)(b) It is technologically and economically feasible for the reconstructed source to meet the relevant standards established by the administrator or by the department pursuant to section 112 of the act (42 USC 7412). Upon reconstruction, an affected source, or a stationary source that becomes an affected source, is subject to relevant standards for new MACT sources, including compliance dates, irrespective of any change in emissions of hazardous air pollutants from that source. NR 460.02 NoteNote: The question of whether a relocated source is reconstructed is addressed in s. NR 460.05 (3m). NR 460.02(33)(33) “Regulation promulgation schedule” means the schedule for the promulgation of emission standards under 40 CFR part 63, established by the administrator pursuant to section 112 (e) of the act (42 USC 7412 (e)) and published in the federal register. NR 460.02(34)(a)(a) “Relevant standard” means any of the following established pursuant to section 112 of the Act (42 USC 7412) that applies to the collection of equipment, activities, or both regulated by the standard or limitation:
