요약

EPA is proposing to approve a State Implementation Plan revision, submitted by the California Air Resources Board on November 8, 2004, that includes the 2004 Revision to the California State Implementation Plan for Carbon Monoxide, Updated Maintenance Plan for Ten Federal Planning Areas. This revision will provide a ten-year update to the carbon monoxide maintenance plan, as well as replace existing and establish new carbon monoxide motor vehicle emissions budgets for the purposes of determining transportation conformity, for the following ten areas: Bakersfield Metropolitan Area, Chico Urbanized Area, Fresno Urbanized Area, Lake Tahoe North Shore Area, Lake Tahoe South Shore Area, Modesto Urbanized Area, Sacramento Urbanized Area, San Diego Area, San Francisco-Oakland-San Jose Area, and Stockton Urbanized Area. In connection with the motor vehicle emissions budgets, we are proposing to deny a request by the California Air Resources Board for EPA to limit the duration of our approval of the budgets. Lastly, EPA is proposing to correct certain errors made in our 1998 final rule approving California's redesignation request for these ten planning areas.
