A. Discharges
covered under this section. The requirements listed under this section apply to
stormwater discharges associated with industrial activity from the following
types of facilities in the primary metal industry, and generally described by
the SIC codes shown:
1. Steel works, blast
furnaces, and rolling and finishing mills, including steel wire drawing and
steel nails and spikes; cold-rolled steel sheet, strip, and bars; and steel
pipes and tubes (SIC Codes 3312-3317).
2. Iron and steel foundries, including gray
and ductile iron, malleable iron, steel investment, and steel foundries not
elsewhere classified (SIC Codes 3321-3325).
3. Rolling, drawing, and extruding of
nonferrous metals, including rolling, drawing, and extruding of copper;
rolling, drawing, and extruding of nonferrous metals except copper and
aluminum; and drawing and insulating of nonferrous wire (SIC Codes
3351-3357).
4. Nonferrous foundries
(castings), including aluminum die-castings, nonferrous die-castings, except
aluminum, aluminum foundries, copper foundries, and nonferrous foundries,
except copper and aluminum (SIC Codes 3363-3369).
