The EPA is announcing the approval of a revision to the maintenance plan prepared by Kansas to maintain the 1-hour national ambient air quality standard (NAAQS) for ozone in the Kansas portion of the Kansas City maintenance area through the year 2012. This plan is applicable to Johnson and Wyandotte Counties. This revision is required by the Clean Air Act.

The effect of this approval is to ensure Federal enforceability of the state air program plan and to maintain consistency between the state-adopted plan and the approved SIP.
