Chris Grundler, the Environmental Protection Agency’s new director of transportation and air quality, said December 13 that he hopes the agency will soon send proposed Tier 3 vehicle and gasoline standards to the White House Office of Management and Budget for interagency review. The agency is aiming to finalize the standards by the end of next year, thus harmonizing federal and California standards and allowing automakers enough time to build compliant vehicles for model year 2017.
