This document contains corrections to the preamble and codification of a final rule which was published on March 23, 2004 (69 FR 13474). The rule being corrected approved revisions to Illinois' definition of volatile organic material (VOM) or volatile organic compound (VOC) contained in the Illinois State Implementation Plan (SIP). Because of the errors in the March 23, 2004, direct final rule which necessitated correction, EPA is extending the public comment period for 30 days from the publication of this correction and delaying the effective date of the direct final rule for 60 days from the date of the publication of this correction. This will provide the public with an opportunity to comment on the corrected rule before it takes effect.
