* 2030 budget is applicable to all future years beyond 2030. ** Based on CARB’s Proposed State Strategy for California’s 2007 SIP affecting on-road mobile categories (w/o long-term strategies) *** Rounded up to the nearest ton. PM2.5 emissions are expected to continue to increase in 2023 and beyond due to increases in VMT. This increase is nominal and will be offset by decreases in NOx emissions such that the 2014 PM2.5 ambient air quality standard will be maintained.TABLE 6-8 Motor Vehicle Emissions Budgets: 8 Hour Ozone (Summer Planning - Tons Per Day)*

These budgets account for an area previously outside the transportation modeling boundary but within the Coachella portion of the Salton Sea Air Basin non attainment area. These emissions are in a downwind, mostly uninhabited, mountainous area and do not effect the attainment demonstration for the nonattainment area. 2008 2011 2014 2017 2018 VOC Baseline Inventory 8.4 7.1 6.1 5.3 5.1
