Start Preamble


Environmental Protection Agency (EPA).


Proposed rule.


EPA is proposing to approve a State Implementation Plan (SIP) revision submitted by the Governor of Colorado with a letter dated March 24, 2005. This revision updates the Long-Term Strategy of the Visibility SIP to establish strategies, activities, and monitoring plans that constitute reasonable progress toward the National visibility goal. 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 Start Printed Page 3797of the rule that are not the subject of an adverse comment.
