What are Some Operations’ Emissions Impacted by Subpart SSSS?
  • An effected source is the collection of all the metal coil coating lines at the source.
  • Coil coating lines are the collection of equipment used to apply an organic coating to the surface of a metal coil.

  • A metal coil is a continuous metal strip that is at least 0.15 mm(0.006 in) thick and is packaged in a roll or coil prior to coating, but does not include metal webs that are coated for use in flexible packaging.

  • to multiple lines as a group, or
  • to the entire affected source.
options cont d
Options (cont’d.)
  • The effected source may use different compliance options for different coil coating lines, or
  • At different times on the same line.
options cont d23
Options (cont’d.)
  • However, the source may not use different compliance options at the same time on the same coil coating line.
  • If the source switches between compliance options for any coil coating line or group of lines, you must document this switch as required by § 63.5190(a), and
