          - 40 CFR Part 52 
          - [CO-001-0041b, CO-001-0042b, UT-001-0032b; FRL-6889-3] 

# AGENCY:

Environmental Protection Agency (EPA). 

# ACTION:

Proposed rule. 

# SUMMARY:

                        EPA is proposing to approve two State Implementation Plan (SIP) revisions: one submitted by the Governor of the State of Colorado on May 10, 2000; and the other submitted by the Governor of the State of Utah on June 14, 1999. The two revisions contain the 1996 periodic carbon monoxide (CO) emission inventories for Denver, Colorado, Fort Collins, Colorado, and Utah County, Utah that were submitted to satisfy the requirements of section 187(a)(5) of the Clean Air Act (CAA), as amended in 1990. 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 the direct final 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.
