          - 40 CFR Part 52 
          - [RME Docket Number R08-OAR-2004-CO-0003; FRL-7822-4] 

# AGENCY:

Environmental Protection Agency (EPA). 

# ACTION:

Proposed rule. 

# SUMMARY:

                        EPA is proposing to take direct final action approving a State Implementation Plan (SIP) revision submitted by the State of Colorado. On April 12, 2004, the Governor of Colorado submitted a revised maintenance plan for the Longmont carbon monoxide (CO) maintenance area for the CO National Ambient Air Quality Standard (NAAQS). The revised maintenance plan contains revised transportation conformity motor vehicle emission budgets for the years 2010 through 2014 and 2015 and beyond. EPA is proposing approval of the Longmont CO revised maintenance plan and the revised transportation conformity motor vehicle emission budgets. This action is being taken under section 110 of the Clean Air Act. In the “Rules and Regulations” section of this                         **Federal Register**                        , EPA is approving the State's SIP revision as a direct final rule without prior proposal because the Agency views this as a noncontroversial SIP revision and anticipates no adverse comments. A detailed rationale for the approval is set forth in the preamble to the direct final rule. If EPA receives no adverse comments, EPA will not take further action on this proposed rule. If EPA receives adverse comments, EPA will withdraw the direct final rule and it will not take effect. EPA will address all public comments in a subsequent final rule based on this proposed rule. EPA will not institute a second comment period on this action. Any parties interested in commenting must 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, EPA may adopt as final those provisions of the rule that are not the subject of an adverse comment.
