On March 23, 2000, EPA promulgated national emission standards for hazardous air pollutants (NESHAP) for secondary aluminum production under section 112 of the Clean Air Act (CAA), and on September 24, 2002, and on December 30, 2002, we published final amendments to the standards based on two separate settlement agreements. These amendments further clarify regulatory text, correct errors, and improve understanding of the rule requirements as promulgated. We are making the amendments by direct final rule, without prior proposal, because we view the revisions as noncontroversial and anticipate no adverse comments.
