NR 462.01(4)(c)(c) An electric utility steam generating unit that is a fossil fuel-fired combustion unit of more than 25 megawatts that serves a generator that produces electricity for sale. A fossil fuel-fired unit that cogenerates steam and electricity, and supplies more than one-third of its potential electric output capacity, and more than 25 megawatts electrical output, to any utility power distribution system for sale is considered an electric utility steam generating unit. NR 462.01(4)(d)(d) A boiler or process heater required to have a permit under section 3005 of the Solid Waste Disposal Act or covered by 40 CFR part 63, subpart EEE, such as a hazardous waste boiler. NR 462.01(4)(g)(g) A boiler or process heater that is used specifically for research and development. This does not include units that only provide heat or steam to a process at a research and development facility. NR 462.01(4)(k)(k) Blast furnace stoves as described in the EPA document entitled “National Emission Standards for Hazardous Air Pollutants for Integrated Iron and Steel Plants--Background Information for Proposed Standards,” EPA-453/R-01-005, incorporated by reference in s. NR 484.06 (4) (d). NR 462.01(4)(m)(m) Any boiler and process heater specifically listed as an affected source in another standard established under section 129 of the Act. NR 462.01(5)(a)(a) If you have a new or reconstructed boiler or process heater, you shall comply with this chapter by November 12, 2004 or upon startup of your boiler or process heater, whichever is later. NR 462.01(5)(b)(b) If you have an existing boiler or process heater, you shall comply with this chapter no later than September 13, 2007. NR 462.01(5)(c)(c) If you have an area source that increases its emissions or its potential to emit such that it becomes a major source of HAP, subds. 1. and 2. apply to you. NR 462.01(5)(c)1.1. Any new or reconstructed boiler or process heater at the existing facility shall be in compliance with this chapter upon startup. NR 462.01(5)(c)2.2. Any existing boiler or process heater at the existing facility shall be in compliance with this chapter within 3 years after the facility becomes a major source. NR 462.01(5)(d)(d) You shall meet the notification requirements in s. NR 462.07 (1) according to the schedule in s. NR 462.07 (1) and in ch. NR 460. Some of the notifications shall be submitted before you are required to comply with the emission limits and work practice standards in this chapter. NR 462.01 HistoryHistory: CR 05-116: cr.

NR 462.02(2)(2) “Bag leak detection system” means an instrument that is capable of monitoring particulate matter loadings in the exhaust of a fabric filter, i.e., baghouse, in order to detect bag failures. A bag leak detection system includes an instrument that operates on electrodynamic, triboelectric, light scattering, light transmittance or other principle to monitor relative particulate matter loadings. NR 462.02(3)(3) “Biomass fuel” means unadulterated wood as defined in sub. (49); wood residue and wood products, such as trees, tree stumps, tree limbs, bark, lumber, sawdust, sander dust, chips, scraps, slabs, millings and shavings; animal litter; vegetative agricultural and silvicultural materials, such as logging residues, nut and grain hulls and chaff, bagasse, orchard prunings, corn stalks, coffee bean hulls and grounds. NR 462.02(4)(4) “Blast furnace gas fuel-fired boiler or process heater” means an industrial, commercial or institutional boiler or process heater that receives 90% or more of its total heat input, based on an annual average, from blast furnace gas. NR 462.02(5)(5) “Boiler” means an enclosed device using controlled flame combustion and having the primary purpose of recovering thermal energy in the form of steam or hot water. Waste heat boilers are excluded from this definition. NR 462.02(6)(6) “Coal” means all solid fuels classifiable as anthracite, bituminous, subbituminous or lignite by the American Society for Testing and Materials in ASTM D388-99e1, “Standard Classification of Coals by Rank”, incorporated by reference in s. NR 484.10 (7), coal refuse and petroleum coke. This definition includes synthetic fuels derived from coal for the purpose of creating useful heat, including solvent-refined coal, coal-oil mixtures and coal-water mixtures. Coal derived gases are excluded from this definition. NR 462.02(7)(7) “Coal refuse” means any by-product of coal mining or coal cleaning operations with an ash content greater than 50% by weight and a heating value less than 13,900 kilojoules per kilogram (6,000 Btu per pound) on a dry basis.
