subch. III of ch. NR 463 Subchapter III — Iron and Steel Foundries

NR 463.21 NR 463.21 What this subchapter covers.

NR 463.21(1) (1) What is the purpose of this subchapter? This subchapter establishes national emission standards for hazardous air pollutants (NESHAP) for iron and steel foundries. This subchapter also establishes requirements to demonstrate initial and continuous compliance with the emissions limitations, work practice standards and operation and maintenance requirements in this subchapter.

NR 463.21(2) (2) Am I subject to this subchapter? You are subject to this subchapter if you own or operate an iron and steel foundry that is, or is part of, a major source of hazardous air pollutant (HAP) emissions. Your iron and steel foundry is a major source of HAP for purposes of this subchapter if it emits or has the potential to emit any single HAP at a rate of 10 tons or more per year or any combination of HAP at a rate of 25 tons or more per year or if it is located at a facility that emits or has the potential to emit any single HAP at a rate of 10 tons or more per year or any combination of HAP at a rate of 25 tons or more per year.

NR 463.21(3) (3) What parts of my foundry does this subchapter cover?

NR 463.21(3)(a) (a) The affected source is a new or existing iron and steel foundry.

NR 463.21(3)(b) (b) This subchapter covers emissions from metal melting furnaces, scrap pre-heaters, pouring areas, pouring stations, automated conveyor and pallet cooling lines, automated shakeout lines and mold and core making lines. This subchapter also covers fugitive emissions from foundry operations.

NR 463.21(3)(c) (c) An affected source is existing if you commenced construction or reconstruction of the affected source before December 23, 2002.

NR 463.21(3)(d) (d) An affected source is new if you commenced construction or reconstruction of the affected source on or after December 23, 2002. An affected source is reconstructed if it meets the definition of “reconstruction’’ in s. NR 463.22.

NR 463.21(4) (4) When do I have to comply with this subchapter?

NR 463.21(4)(a) (a) Except as specified in par. (b), if you have an existing affected source, you shall comply with each emissions limitation, work practice standard and operation and maintenance requirement in this subchapter that applies to you no later than April 23, 2007. Major source status for existing affected sources shall be determined no later than April 23, 2007.

NR 463.21(4)(b) (b) If you have an existing affected source, you shall comply with the work practice standards in s. NR 463.23 (2) (b) or (c), as applicable, no later than April 22, 2005.
