On November 18, 2010, the ARB approved the PM10 Implementation/Maintenance Plan and Redesignation Request for Sacramento County. The plan shows that the 1987 standard for PM10 was attained and establishes the strategy for maintaining the standard through 2022.
On March 26, 2009, the ARB approved the 2009 Sacramento Regional 8-Hour Ozone Attainment and Reasonable Further Progress Plan. The plan sets out a strategy for attaining the 1997 federal 8-hour ozone standard in the Sacramento Nonattainment Area by 2018.
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.
