Approval and Promulgation of Air Quality Implementation Plans; 
State of Colorado; Second Ten-Year Carbon Monoxide Maintenance Plan for 
Fort Collins

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to approve a State Implementation Plan (SIP) 
revision submitted to EPA by the State of Colorado. On May 25, 2011, 
the Governor of Colorado's designee submitted a Clean Air Act (CAA) 
section 175A(b) second 10-year maintenance plan for the Fort Collins 
area for the carbon monoxide (CO) National Ambient Air Quality Standard 
(NAAQS). This limited maintenance plan (LMP) addresses maintenance of 
the CO NAAQS for a second 10-year period beyond the original 
redesignation. This action is being taken under sections 110 and 175A 
of the CAA.

SUPPLEMENTARY INFORMATION: In the ``Rules'' section of this Federal 
Register, EPA is approving Colorado'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. 
See the information provided in the Direct Final action of the same 
title which is located in the Rules section of this Federal Register.

    Authority:  42 U.S.C. 7401 et seq.

    Dated: August 26, 2013.
