NR 440.46(1)(a)(a) Each glass melting furnace is an affected facility to which the provisions of this section apply. NR 440.46(1)(b)(b) Any facility under par. (a) that commences construction or modification after June 15, 1979, is subject to the requirements of this section. NR 440.46(1)(c)(c) This section does not apply to hand glass melting furnaces, glass melting furnaces designed to produce less than 4.55 Mg (5 tons) of glass per day and all-electric melters. NR 440.46(2)(2) Definitions. As used in this section, terms not defined in this subsection have the meanings given in s. NR 440.02, unless otherwise required by the context. NR 440.46(2)(a)(a) “All-electric melter” means a glass melting furnace in which all the heat required for melting is provided by electric current from electrodes submerged in the molten glass, although some fossil fuel may be charged to the furnace as raw material only. NR 440.46(2)(b)(b) “Borosilicate recipe” means glass product composition of the following approximate ranges of weight proportions: 60 to 80% silicon dioxide, 4 to 10% total (e.g., and ), 5 to 35% boric oxides and 0 to 13% other oxides. NR 440.46(2)(c)(c) “Container glass” means glass made of soda-lime recipe, clear or colored, which is pressed or blown, or both, into bottles, jars, ampoules and other products listed under SIC code 3221 in the Standard Industrial Classification Manual, incorporated by reference in s. NR 440.17. NR 440.46(2)(cm)(cm) “Experimental furnace” means a glass melting furnace with the sole purpose of operating to evaluate glass melting processes, technologies, or glass products. An experimental furnace does not produce glass that is sold (except for further research and development purposes) or that is used as a raw material for nonexperimental furnaces. NR 440.46(2)(d)(d) “Flat glass” means glass made of soda-lime recipe and produced into continuous flat sheets and other products listed under SIC code 3211 in the Standard Industrial Classification Manual, incorporated by reference in s. NR 440.17. NR 440.46(2)(dm)(dm) “Flow channels” means appendages used for conditioning and distributing molten glass to forming apparatuses and are a permanently separate source of emissions such that no mixing of emissions occurs with emissions from the melter cooling system prior to their being vented to the atmosphere. NR 440.46(2)(e)(e) “Glass melting furnace” means a unit comprising a refractory vessel in which raw materials are charged, melted at high temperature, refined and conditioned to produce molten glass. The unit includes foundations, superstructure and retaining walls, raw material charger systems, heat exchangers, melter cooling system, exhaust system, refractory brick work, fuel supply and electrical boosting equipment, integral control systems and instrumentation and appendages for conditioning and distributing molten glass to forming apparatuses. The forming apparatuses, including the float bath used in flat glass manufacturing and flow channels in wool fiberglass and textile manufacturing, are not considered part of the glass melting furnace. NR 440.46(2)(f)(f) “Glass produced” means the weight of the glass pulled from the glass melting furnace. NR 440.46(2)(g)(g) “Hand glass melting furnace” means a glass furnace where the molten glass is removed from the furnace by a glassworker using a blowpipe or a pontil. NR 440.46(2)(h)(h) “Lead recipe” means glass product composition of the following ranges of weight proportions: 50 to 50% silicon dioxide, 18 to 35% lead oxides, 5 to 20% total R2O (e.g., Na2O and K2O), 0 to 8% total R2O3 (e.g., ), 0 to 15% total RO (e.g., CaO, MgO), other than lead oxide, and 5 to 10% other oxides.
