ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R08-OAR-2006-0125; FRL-8047-2]


Approval and Promulgation of Air Quality Implementation Plans; 
Colorado; Revisions to Regulation No. 1; Proposed Rule

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 April 12, 2004. This 
revision makes a minor change to Colorado Regulation No. 1. The 
intended effect of this action is to make federally enforceable those 
provisions that EPA is approving. 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.

DATES: Written comments must be received on or before April 24, 2006.
