Steamboat Springs

AGENCY: Environmental Protection Agency.

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing 
approval of the State Implementation Plan (SIP) revisions submitted by 
the State of Colorado. On May 11, 2012, the designee of the Governor of 
Colorado submitted to EPA a revised maintenance plan for the Steamboat 
Springs area for the National Ambient Air Quality Standards (NAAQS) for 
particulate matter with an aerodynamic diameter less than or equal to 
10 microns (PM<INF>10</INF>). The SIP was adopted by the State on 
December 15, 2011. As required by Clean Air Act (CAA) section 175A, 
this revised maintenance plan addresses maintenance of the 
PM<INF>10</INF> standard for a second 10-year period beyond the area's 
original redesignation to attainment for the PM<INF>10</INF> NAAQS. In 
addition, EPA is proposing approval of the revised maintenance plan's 
2024 transportation conformity motor vehicle emissions budget for 
PM<INF>10.</INF> This action is being taken under sections 110 and 175A 
of the CAA.

SUPPLEMENTARY INFORMATION: In the Rules section of this Federal 
Register, the EPA is approving the State's SIP revision through 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. Then, 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.
