Implementation Plans; Colorado; Enhanced Motor Vehicle Inspection and 
Maintenance Program

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: EPA is conditionally approving a vehicle inspection and 
maintenance (I/M) State Implementation Plan (SIP) revision based on the 
Governor's June 24, 1994 commitment to adopt final regulations for 
dealership self-testing within one year of the conditional approval. If 
this commitment is not met, the conditional approval will automatically 
convert to a disapproval. This revision establishes and requires the 
implementation of an enhanced motor vehicle inspection and maintenance 
(I/M) program in the Denver and Boulder urbanized areas, including all 
or part of the Colorado counties of Adams, Arapahoe, Boulder, Denver 
County, Douglas, Jefferson. This action is being taken under section 
110 of the Clean Air Act (CAA).

EFFECTIVE DATE: This final rule is effective on December 8, 1994.

SUPPLEMENTARY INFORMATION:

I. Introduction

    On July 14, 1994 (59 FR 35875), EPA published a notice of proposed 
rulemaking (NPR) for the State of Colorado. The NPR proposed 
conditional approval of an enhanced vehicle I/M program in the Denver 
and Boulder urbanized areas, including all or part of the Colorado 
counties of Adams, Arapahoe, Boulder, Denver County, Douglas, 
Jefferson. On January 14, 1994, and on June 24, 1994, Roy Romer, 
Governor of the State of Colorado, submitted to EPA enhanced I/M SIP 
revisions for the Denver and the Boulder urbanized areas. Public 
hearings were held on November 12, 1993, and December 16, 1993, for the 
January 14, 1994 SIP submittal, and are to be held on September 15, 
1994, for the June 24, 1994, SIP submittal, as detailed in the 
Governor's June 24, 1994 letter. More detailed analyses of the State's 
submittals are contained in the NPR action as published July 14, 1994. 
Other specific requirements of the enhance I/M program and the 
rationale for EPA's action are explained in the NPR and will not be 
restated here. No public comments were received on the NPR.

II. Final Action

    EPA is conditionally approving the Colorado enhanced motor vehicle 
I/M program. Conditional approval is based on the State's commitment to 
adopt final regulations for dealership self-testing within one year of 
final conditional approval. If such conditions are not met by this 
date, the conditional approval will automatically become a disapproval.

III. Administrative Review

    Nothing in this action should be construed as permitting or 
allowing or establishing a precedent for any future request for 
revision to any SIP. Each request for revision to the SIP shall be 
considered separately in light of specific technical, economic, and 
environmental factors and in relation to relevant statutory and 
regulatory requirements.
    OMB has exempted these actions from review under Executive Order 
12866.
    Under section 307(b)(1) of the Clean Air Act, petitions for 
judicial review of this action must be filed in the United States Court 
of Appeals for the appropriate circuit by January 9, 1995. Filing a 
petition for reconsideration by the Administrator of this final rule 
does not affect the finality of this rule for the purposes of judicial 
review nor does it extend the time within which a petition for judicial 
review may be filed and shall not postpone the effectiveness of such 
rule or action. This action may not be challenged later in proceedings 
to enforce its requirements. (See section 307(b)(2)) (See 42 U.S.C. 
7607 (b)(2)).
