Approval and Promulgation of Implementation Plans; New Mexico; 
Revision to Motor Vehicle Emission Budgets in Bernalillo County, NM 
Carbon Monoxide Air Quality Maintenance Plan Using MOBILE6

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: The EPA is proposing to approve the State Implementation Plan 
(SIP) revisions for Bernalillo County, New Mexico, which is a carbon 
monoxide maintenance area. This SIP revision was submitted to EPA by 
the Governor of New Mexico on May 15, 2003. More specifically, EPA is 
proposing approval of the county's revised Motor Vehicle Emissions 
Budget (MVEB) for carbon monoxide (CO) for 1996, 1999, 2002, 2005 and 
2006. This budget was developed using EPA's latest emissions modeling 
program, MOBILE6. This submittal updates the maintenance plan by 
establishing new transportation conformity MVEBs for use by the Mid-
Region Council of Governments, the area's Metropolitan Planning 
Organization (MPO). These budgets will continue to maintain the total 
on-road mobile source emissions for the area at or below the attainment 
level for the CO National Ambient Air Quality Standard (NAAQS).

DATES: Written comments must be received on or before November 10, 
2003.

ADDRESSES: Comments on this action may submitted either by mail or 
electronically. Written comments should be mailed to Mr. Thomas H. 
Diggs, Chief, Air Planning Section (6PD-L),U.S. Environmental 
Protection Agency, 1445 Ross Avenue, Suite 700, Dallas, Texas 75202-
2733. Comments may also be submitted electronically via email to 
[email protected] or to http://www.regulations.gov which is an 
alternative method for submitted electronic comments to EPA. To submit 
comments, please follow the detailed instructions described in the 
``Final Action'' section of the direct final rule which is located in 
the Rules and Regulations section of this Federal Register.

FOR FURTHER INFORMATION CONTACT: Ms. Peggy Wade of the EPA Region 6 Air 
Planning Section at (214)665-7247 or [email protected].

SUPPLEMENTARY INFORMATION: In the Final Rules section of this Federal 
Register, EPA is approving the State's SIP submittal as a direct final 
rule without prior proposal because the Agency views this as a 
noncontroversial submittal and anticipates no adverse comment. A 
detailed rationale for the approval is set forth in the direct final 
rule. If no adverse comments are received in response to this action, 
no further activity is contemplated. If EPA receives adverse comments, 
the direct final rule will be withdrawn and all public comments 
received will be addressed in a subsequent final rule based on this 
proposed rule. EPA will not institute a second comment period. Any 
parties interested in commenting on this action should do so at this 
time. Please note that if EPA receives adverse comment on an amendment, 
paragraph, or section of this rule and if that provision may be severed 
from the remainder of the rule, we may adopt as final those provisions 
of the rule that are not the subject of an adverse comment.
    For additional information, see the Direct Final rule which is 
located in the Rules and Regulations section of this Federal Register.

    Dated: September 30, 2003.
