Description: 

The Environmental Protection Agency (EPA) is taking final action to approve portions of two state implementation plan (SIP) revisions submitted by the State of California to meet Clean Air Act (CAA or ``Act'') requirements for the 2008 8-hour ozone national ambient air quality standards (NAAQS or ``standards'') in the Sacramento Metro ozone nonattainment area (``Sacramento Metro Area''). These SIP revisions address the CAA nonattainment area requirements for the 2008 ozone NAAQS, such as the requirements for an emissions inventory, an attainment demonstration, reasonable further progress, reasonably available control measures, and contingency measures, and it establishes motor vehicle emissions budgets. The EPA is taking final action to approve these revisions as meeting all the applicable ozone nonattainment area requirements, except for the State's contingency measures revision. The EPA is deferring action on this revision related to contingency measures.
