(1) WHAT IS THE
PURPOSE OF THIS SUBCHAPTER? This subchapter establishes national emission

continuous compliance with the emissions limitations, work practice standards
and operation and maintenance requirements in this subchapter.
(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.
(3) WHAT PARTS OF MY FOUNDRY DOES THIS
SUBCHAPTER COVER?
(a) The affected source is a
new or existing iron and steel foundry.
(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.
(c) An affected
source is existing if you commenced construction or reconstruction of the
affected source before December 23, 2002.
(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
