[EPA-R08-OAR-2007-0465; FRL-8453-4]


Approval and Promulgation of Air Quality Implementation Plans; 
State of Colorado; Revised Denver and Longmont Carbon Monoxide 
Maintenance Plans, and Approval of Related Revisions

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 September 25, 2006, the Governor's designee submitted revised 
maintenance plans for the Denver metropolitan and Longmont carbon 
monoxide (CO) maintenance areas for the CO National Ambient Air Quality 
Standard (NAAQS). These revised maintenance plans address maintenance 
of the CO standard for a second ten-year period beyond redesignation, 
extend the horizon years, and contain revised transportation conformity 
budgets. In addition, Regulation No. 11, ``Vehicle Emission Inspection 
Program,'' and Regulation No. 13, ``Oxygenated Fuels Program,'' are 
removed from Denver's and Longmont's revised CO maintenance plans. EPA 
is proposing approval of the revised Denver and Longmont CO maintenance 
plans, and the revised transportation conformity budgets. In addition, 
EPA is proposing to approve the removal of Regulation No. 11 and 
Regulation No. 13 from Denver's and Longmont's revised CO maintenance 
plans. 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 the 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.

DATES: Written comments must be received on or before September 17, 
2007.
