California State Implementation Plans

This page last reviewed September 19, 2016


ARB released the updated Mobile Source Strategy on May 16, 2016 that demonstrates how the State will simultaneously meet air quality standards, achieve greenhouse gas emission reduction targets, reduce petroleum consumption, and decrease health risk from transportation emissions over the next fifteen years.  
On September 1, 2016, ARB held a public workshop regarding the Proposed 2016 State Strategy for the State Implementation Plan (State SIP Strategy) to discuss the strategy and proposed control measures designed to achieve emission reductions from mobile sources, fuels, and consumer products necessary to meet ozone and fine particulate matter attainment deadlines established by the Clean Air Act.

ARB released the Proposed State SIP Strategy on May 17, 2016, including the corresponding Draft Environmental Analysis as required by the California Environmental Quality Act.

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.

Submittal of Waiver and Authorization Measures into the California SIP
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 list of measures and related board hearing documents can be found here.

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.
