The Coachella Valley is classified as a severe-15 nonattainment area for the 2008 8-hour ozone standard and subject to Clean Air Act Transportation Conformity. This regulation requires that the total emissions from transit and highway vehicles not exceed the Motor Vehicle Emissions Budget (MVEB) included in the latest approved SIP. As of November 4, 2022, the Coachella Valley is in transportation conformity lockdown, a situation caused by new estimates of emissions which exceed the MVEB included in the latest approved SIP. This is due to updates in the methodology to estimate the emissions, not due to increased vehicle activities. Specifically, the on-road emissions model EMFAC2017 estimates higher emissions for the same vehicle activities compared to EMFAC2014. To resolve the conformity lockdown, South Coast AQMD seeks to reclassify Coachella Valley from severe-15 to extreme for the 2008 8-hour ozone standard and update the MVEB.
