Disapproval of Implementation Plan Revisions; State of California; South Coast VMT Emissions Offset Demonstrations

EPA is taking final action to withdraw its previous approvals of state implementation plan revisions submitted by the State of California to meet the vehicle-miles-traveled emissions offset requirement under the Clean Air Act for the Los Angeles-South Coast Air Basin 1-hour and 8-hour ozone nonattainment areas. EPA is also taking final action to disapprove the same plan revisions. EPA is finalizing the withdrawal and disapproval actions in response to a remand by the Ninth Circuit Court of Appeals in Association of Irritated Residents v. EPA. The effect of this action is to trigger deadlines by which new plan revisions meeting the applicable requirements must be submitted by the State of California and approved by EPA to avoid sanctions and to avoid an obligation on EPA to promulgate a federal implementation plan.
