California State Implementation Plans

This page last reviewed September 1, 2015


trafficnew button The Monday, September 14, 2015 Workshop regarding the Discussion Draft of ARB's Mobile Source Strategy and SIP Measures has been postponed to a future date and time.

The Submittal of Waiver and Authorization Measures into the California SIP is now available for review.  A recent court decision requires regulations that implement current SIPs and have a federal waiver or authorization be submitted into the California SIP.  Staff has compiled a list of measures that have either already been granted waivers or authorizations or are anticipated to be granted waivers or authorizations for submittal into the California SIP.  

The California Infrastructure SIP revision is now available.  The Board approved the revision at a public hearing on January 23, 2014.  The Infrastructure SIP revision is administrative in nature and covers the National Ambient Air Quality Standards (federal standards) for ozone (1997 and 2008), fine particulate matter (PM2.5; 1997, 2006, and 2012), lead (2008), nitrogen dioxide (2010), and sulfur dioxide (2010).  The proposed revision describes the infrastructure (authorities, resources, and programs) California has in place to implement, maintain, and enforce these federal standards.  It does not contain any proposals for emission control measures.

What is a State Implementation Plan?     

The table below includes information on SIP activities for ozone, carbon monoxide and particulate matter. More specifically, it provides links to the attainment plans and and corresponding documents that are available on ARB's website.

By selecting a nonattainment area on the far left, you will be linked to ARB and District supporting documentation including staff reports, submittal letters, and resolutions.  If you prefer to only view the plan, identify the criteria pollutant and select the appropriate year under the attainment plan column on the right. You may also use the district link tool below to scroll to a specific district.

Resolutions and Executive Orders
ARB uses Board Resolutions and Executive Orders to act on proposed SIP revisions and authorize their inclusion in California's SIP.  The area-specific links in the "ARB and Supporting Documentation" portion of the table below provides links to Board Resolutions and Executive Orders that are available electronically.
