# AGENCY:

Environmental Protection Agency (EPA). 

# ACTION:

Proposed rule. 

# SUMMARY:

                        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.

Information that you consider CBI or otherwise protected should be clearly identified as such and should not be submitted through the agency Web site, eRulemaking portal or e-mail. The agency Web site and eRulemaking portal are “anonymous access” systems, and EPA will not know your identity or contact information unless you provide it in the body of your comment. If you send e-mail directly to EPA, your e-mail address will be automatically captured and included as part of the public comment.

# FOR FURTHER INFORMATION CONTACT:

                        Toby Tiktinsky, EPA Region IX, (415) 947-4223,                         *tiktinsky.toby@epa.gov.*

# SUPPLEMENTARY INFORMATION:

                    In the Rules and Regulations section of this                     **Federal Register**                    , we are approving the 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.*

In addition, EPA is notifying the public that we have found that the carbon monoxide motor vehicle emissions budgets contained in the submitted maintenance plan are adequate for transportation conformity purposes. Related to the motor vehicle emissions budgets, however, we are denying a request by ARB for EPA to limit the duration of our approval of the budgets. Our denial of ARB's request, however, does not affect our approval of the plan itself or the budgets contained therein. Lastly, we are also correcting, pursuant to section 110(k)(6) of the Act, certain errors that we made in our 1998 final rule approving California's redesignation request for these ten planning areas. 

We are taking these actions without prior proposal because we believe that the revision and request are not controversial. If we receive adverse comments, however, we will publish a timely withdrawal of the direct final rule and address the comments in subsequent action based on this proposed rule. We do not plan to open a second comment period, so anyone interested in commenting should do so at this time. If we do not receive adverse comments, no further activity is planned. For further information, please see the direct final action. 

Dated: November 15, 2005.

Acting Regional Administrator, Region IX.
