AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to approve a State Implementation Plan (SIP) 
revision submitted by the State of Colorado. On March 31, 2010, the 
Governor of Colorado's designee submitted to EPA a Clean Air Act (CAA) 
section 175A(b) second 10-year maintenance plan for the Greeley 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

of the CAA.

SUPPLEMENTARY INFORMATION: In the ``Rules and Regulations'' 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 and Regulations 
section of this Federal Register.

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

    Dated: July 16, 2013.
