The EPA is notifying the public that we have found the motor vehicle emissions budgets for the Klamath Falls, Oregon 2006 24-hour fine particulate matter standard nonattainment area adequate for transportation conformity purposes. The budgets were submitted on August 20, 2024, as part of Oregon's Klamath Falls Redesignation Request and Maintenance Plan. As a result of our finding, the Klamath Falls area must use these budgets for future transportation conformity determinations.
