The purpose of this action is to correct an error in the adoption and submittal date shown for a revision to the implementation plan that EPA recently approved and to correct a transcription error in, and to make a more general correction to, the boundary description of the metropolitan Phoenix carbon monoxide area that EPA recently redesignated to attainment.
