California State Implementation Plans
This page last reviewed November 13, 2015
On December 17, 2015, the Board will conduct a public hearing to consider approval of revisions to the California Infrastructure SIP. The proposed revisions, known as the Transport or "Good Neighbor" SIP, describe the nature and potential impact of California emissions on receptors in downwind states. The staff report is now available for review on the Infrastructure SIP webpage.
Information, notices, and documents regarding ARB's 2016 Mobile Source Strategy are now available.
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.
What is a State Implementation Plan?

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.
