## Abstract

On July 26, 1999, the EPA published a direct final rule approving as amendments to the Indiana State Implementation Plan, temporary revised opacity limits for two processes at ALCOA Warrick Operations, which were submitted by the Indiana Department of Environmental Management on December 8, 1998. The preamble of that direct final rule incorrectly identified some of the subject sources. This action corrects this inadvertent error.
