  "definition": "1. Any furnace wherein electrical energy is converted to heat energy by transmission of current between electrodes partially submerged in the furnace charge.\n\n2. Vessel in which forms of iron and steel such as scrap and foundry returns are melted through resistance heating by an electric current flowing through the arcs formed between the electrodes and the surface of the metal and also flowing through the metal between the arc paths.\n\n3. Furnace that produces molten alloy metal and heats the charge materials with electric arcs from carbon electrodes.\n\n4. Furnace that produces molten steel and heats the charge materials with electric arcs from carbon electrodes. For the purposes of this subpart, an EAF shall consist of the furnace shell and roof and the transformer. Furnaces that continuously feed direct-reduced iron ore pellets as the primary source of iron are not affected facilities within the scope of this definition.\n\n5. Furnace that produces molten steel and heats the charge materials with electric arcs from carbon electrodes. Furnaces that continuously feed direct-reduced iron ore pellets as the primary source of iron are not affected facilities within the scope of this definition.",
