This page updated March 7 , 2005.

  On April 26, 1996, the Board approved the "Carbon Monoxide Redesignation Request and Maintenance Plan for Ten Federal Planning Areas" as part of the State Implementation Plan (SIP) for Carbon Monoxide.  U.S. EPA approved this revision on June 1, 1998 and redesignated the ten areas to attainment.  On October 22, 1998, ARB revised the SIP to incorporate the effects of the recent Board action to remove the wintertime oxygen requirement for gasoline in certain areas.  On July 22, 2004, ARB approved an update to the SIP that shows how the ten areas will maintain the standard through 2018, revises emission estimates, and establishes new on-road motor vehicle emission budgets for transportation conformity purposes.  Below, you will find 2004 Plan update documents as well as the original 1996 Board action and the 1998 Plan revision.
