Current through June 24, 2024
For terms not defined in this section, the definitions
				  contained in chs.
				  NR
				  400 and 460 apply to the terms in this chapter, with
				  definitions in ch. NR 460 taking precedence over definitions in ch. NR 400. If
				  this section defines a term which is also defined in ch. NR 400 or 460, the
				  definition in this section applies in this chapter. In this chapter:
(1) "Annual capacity factor" means the ratio
				between the actual heat input to a boiler or process heater from the fuels
				burned during a calendar year and the potential heat input to the boiler or
				process heater had it been operated for 8,760 hours during a year at the
				maximum steady state design heat input capacity.
(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.
(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.
(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.
(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.
(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.
(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.
(8) "Commercial or institutional boiler"
				means a boiler used in commercial establishments or institutional
				establishments, such as medical centers, research centers, institutions of
				higher education, hotels and laundries, to provide one or more of the
				following: electricity, steam or hot water.
(9) "Construction and demolition material"
				means waste building materials that result from the construction or demolition
				operations on houses and commercial and industrial buildings.
(10)
(a)
				"Deviation" means any instance in which an affected source subject to this
				chapter, or an owner or operator of an affected source, fails to meet one of
				the following:
1. Any requirement or
				obligation established by this chapter, including any emission limit, operating
				limit or work practice standard.
2.
				Any term or condition that is adopted to implement an applicable requirement in
				this chapter and that is included in the operating permit for any affected
				source required to obtain such a permit.
3. Any emission limit, operating limit or
				work practice standard in this chapter during startup, shutdown or malfunction
				regardless of whether or not the failure is permitted by this
				chapter.
