Specifically, the EPA is approving those portions of the "2018 Plan for the 1997, 2006, and 2012 PM2.5 Standards" and the "San Joaquin Valley Supplement to the 2016 State Strategy for the State Implementation Plan" that pertain to the 2006 PM2.5 NAAQS and address certain CAA requirements for Serious PM2.5 nonattainment areas. In addition, the EPA is approving the "Revision to the California State Implementation Plan for PM2.5 Standards in the San Joaquin Valley" ("PM2.5 Prior Commitment Revision" or "Revision") and finding that the State has complied with this commitment. The EPA is also approving motor vehicle emission budgets and inter-pollutant trading ratios for use in transportation conformity analyses for the 2006 PM2.5 NAAQS. Finally, as part of this action, the EPA is granting an extension of the Serious area attainment date for the 2006 PM2.5 NAAQS in the San Joaquin Valley from December 31, 2019, to December 31, 2024, based on a determination that the State has satisfied the statutory criteria for this extension. ## Source - [Federal Register document](https://www.federalregister.gov/documents/2020/07/22/2020-14471/clean-air-plans-2006-fine-particulate-matter-nonattainment-area-requirements-san-joaquin-valley) --- *AI Analytics · CC0 1.0*
