The EPA is taking direct final action on amendments to the national emission standards for hazardous air pollutants (NESHAP) for leather finishing operations, which were issued on February 27, 2002, under section 112 of the Clean Air Act (CAA). The direct final amendments clarify the frequency for categorizing leather product process types, modify the definition of "specialty leather," add a definition for "vacuum mulling," and add an alternative procedure for determining the actual monthly solvent loss from an affected source. We are issuing the amendments as a direct final rule, without prior proposal, because we view the revisions as noncontroversial and anticipate no significant adverse comments. However, in the Proposed Rules section of this Federal Register, we are publishing a separate document that will serve as the proposal to amend the national emission standards for leather finishing operations if significant adverse comments are filed.
