Environmental Protection Agency January 22, 2009 – Federal Register Recent Federal Regulation Documents

Under the Clean Air Act, EPA is approving certain revisions, and disapproving certain other revisions, to the Nevada State Implementation Plan submitted by the Nevada Division of Environmental Protection. These revisions relate to the application of the State's vehicle inspection and maintenance program to vehicles operated on Federal installations. EPA is also correcting certain plan revisions related to this subject that EPA previously approved in error. The intended effect is to ensure that vehicles operated on Federal installations are subject only to those requirements of the State's vehicle inspection and maintenance program that apply in the same manner and to the same extent to nongovernmental entities.

In this notice, EPA is notifying the public that the Agency has found that the motor vehicle emissions budgets for the years 2011, 2014 and 2017 from the San Joaquin Valley 2007 Ozone Plan are adequate for transportation conformity purposes. In this notice, EPA is also notifying the public that the Agency has found that the motor vehicle emissions budgets for the years 2008, 2020 and 2023 from the San Joaquin Valley 2007 Ozone Plan are inadequate for transportation conformity purposes. The San Joaquin Valley 2007 Ozone Plan was submitted to EPA on November 16, 2007 by the California Air Resources Board (CARB) as a revision to the California State Implementation Plan (SIP), and includes reasonable further progress and attainment demonstrations for the 8-hour ozone standard. On February 1, 2008, CARB submitted supplemental technical information related to reasonable further progress for the 8-hour ozone standard in San Joaquin Valley. As a result of our adequacy findings, the San Joaquin Valley Metropolitan Planning Organizations and the U.S. Department of Transportation must use the adequate budgets, and cannot use the inadequate budgets, for future conformity determinations.
