## Abstract

EPA is approving an amendment to the Missouri State Implementation Plan (SIP).

Related performance standard requirements will remain unchanged. This action is independent and does not affect the revision to the Missouri SIP due in April 2007, in response to the SIP Call issued April 14, 2006, to bring the area of Herculaneum into compliance with the lead National Ambient Air Quality Standard.
