I. Summary of EPA's Actions

We are taking direct final rulemaking action to approve revisions to Colorado's SIP submitted by the Governor on May 10, 2000. This submittal updates Colorado's Regulation 12, Reduction of Diesel Vehicle Emissions. Specifically, this revision removes the program from Colorado Springs, Ft. Collins, and Greeley, or areas outside the Denver particulate matter of 10 microns in size or smaller (PM10) non-attainment boundary. In addition, the May 10, 2000 submittal repeals Regulation 9, Trip Reduction. These regulations are obsolete and have been effectively replaced by other transportation programs.

II. What Is the State's Process To Submit These Materials to EPA?

Section 110(k) of the CAA addresses our actions on submissions of revisions to a SIP. The CAA requires States to observe certain procedural requirements in developing SIP revisions for submittal to us. Section 110(a)(2) of the CAA requires that each SIP revision be adopted after reasonable notice and public hearing. This must occur prior to the revision being submitted by a State to us.

A. Regulation 9, Trip Reduction

The Colorado Air Quality Control Commission (AQCC) held a public hearing on February 17, 2000, to repeal Regulation 9, Trip Reduction, and remove it from the SIP because it has been effectively replaced by other transportation programs. The Denver Regional Council of Governments RideArrangers program, the Regional Transportation District's ECOPass program, and the Transportation Management Associations are all transportation control measures in the SIP and are federally enforceable. The AQCC repealed Regulation 9 on February 17, 2000. This SIP revision became State effective on April 30, 2000, and was submitted by the Governor to us on May 10, 2000.

B. Regulation 12, Reduction of Diesel Vehicle Emissions

The Colorado AQCC held a public hearing on March 16, 2000, for Regulation 12, Reduction of Diesel Vehicle Emissions, to remove the program from the SIP for Colorado Springs, Ft. Collins, and Greeley (areas outside the Denver PM10 non-attainment area). The AQCC adopted the revisions to the SIP on March 16, 2000. This SIP revision became State effective on May 30, 2000, and was submitted by the Governor to us on May 10, 2000.

We have evaluated the Governor's submittal and have determined that the State met the requirements for reasonable notice and public hearing under section 110(a)(2) of the CAA. By operation of law under section 110(k)(1)(B) of the CAA, the Governor's May 10, 2000, submittal became complete on November 10, 2000.

III. Evaluation of the State's Submittal

A. Regulation 9, Trip Reduction

Colorado's Regulation 9 is entitled “Trip Reduction.” In this action, we are approving Colorado's May 10, 2000, repeal and removal of Regulation 9 from the SIP, as adopted by the AQCC on February 17, 2000, and State effective on April 30, 2000. The purpose of Regulation 9 was to promote alternatives to single occupancy driving, but did not itself establish alternative transportation measures. Rather, Regulation 9 required government and large businesses to provide employees with information regarding public transit, ride sharing, and other emission-reducing means of travel, as well as providing bicycle and car pool parking at the employment site. Regulation 9 was identified as one of many possible transportation control measures in the 1979 Ozone SIP; however, no emissions reduction credit was specifically assigned to Regulation 9.

Regulation 9 was partially implemented by the State between 1979 and 1983, at which point the State ceased further activity with respect to this regulation. Subsequent SIP revisions failed to identify Regulation 9 as a transportation control measure. The Governor submitted a SIP revision in 1990 to remove this regulation from the SIP, but EPA returned this SIP revision to the Governor in 1991 as incomplete. The ozone maintenance plan for Denver submitted in August 1996 demonstrated maintenance of the ozone standard without Regulation 9, and revisions to this maintenance plan recently adopted by the AQCC for hearing also demonstrate that Regulation 9 is not necessary for maintenance of the ozone standard. The regulation has been effectively superseded by several other SIP and non-SIP transportation programs such as Denver Regional Council of Government's RideArrangers program, the Regional Air Quality Council's Ozone Action Day program, the Regional Transportation District's ECOPass program, and Transportation Management Associations which develop and implement travel reduction programs, promote alternative transportation measures, and provide assistance to employers with travel reduction. The Denver Regional Council of Governments RideArrangers program, the Regional Transportation District's ECOPass program, and the Transportation Management Associations are all transportation control measures in the SIP and are federally enforceable.

On November 30, 2000, the Governor of Colorado submitted a revised redesignation request and maintenance plan for the 1-hour ozone standard for Denver. Colorado was able to demonstrate maintenance of the ozone National Ambient Air Quality Standards (NAAQS) with out emission reduction credit assigned to Regulation 9. In addition, Regulation 9 was not referred to as a transportation control measure in the ozone SIP. We are currently processing Denver's redesignation request and maintenance plan for the 1-hour ozone standard and expect approval of Denver's plan in Summer 2001.

Section 110(l) and 193 of the CAA states that no control requirement may be modified in a nonattainment area unless the modification insures equivalent or greater emission reductions of the specified air pollutant. Because we are currently redesignating Denver to attainment for the 1-hour ozone standard and expect approval of the redesignation request and maintenance plan in Summer 2001, we have determined Regulation 9 can be repealed. Furthermore, Regulation 9 does not directly affect a specific pollutant, but rather Regulation 9 was aimed at reducing vehicle miles traveled, which has been made up for by other transportation programs. Regulation 9 has been effectively Start Printed Page 47085replaced by other programs, and thus, it may be removed from the SIP.

B. Regulation 12, Reduction of Diesel Vehicle Emissions

Colorado's Regulation 12 is entitled “Reduction of Diesel Vehicle Emissions.” In this action, we are approving Colorado's May 10, 2000, revisions to Regulation 12, as adopted by the AQCC on March 16, 2000, and State effective on May 30, 2000, and note these revisions supersede and replace the version of Regulation 12 that we approved on November 19, 1992 (57 FR 54509). We note that the Governor submitted another revision to Regulation 12 prior to May 10, 2000, that we never approved and that the Governor's May 10, 2000, submittal also supersedes and replaces this other revision to Regulation 12.

Regulation 12 was revised to remove the “Reduction of Diesel Vehicle Emissions” program from the SIP for the areas of Colorado Springs, Ft. Collins, and Greeley (El Paso County, Larimer County, and Weld County.) Regulation 12 is a control measure relied upon to demonstrate attainment in the Denver PM10 SIP. The entire diesel program was included in the SIP which includes El Paso County, Larimer County, and Weld County. The program will be retained as a State only enforceable program in those areas, and will be retained in the SIP for the Denver metro area. The program is not necessary to meet the federal requirements outside the non-attainment area, and thus, the SIP revisions are approvable. The diesel inspection programs established in Regulation 12, are federally required because the State took emissions reduction credit for such program in the attainment demonstration for the 1995 Denver PM10 SIP.

In addition, the revision corrects the statutory reference defining the areas of applicability, as well as statutory references that specify eligible vehicles. These non-substantive, editorial corrections are approvable.

IV. Final Action

In this action, we are approving the State of Colorado's revisions to Regulation 12, Reduction of Diesel Vehicle Emissions. We are also approving the repeal of Colorado's Regulation 9, Trip Reduction. These SIP revisions were submitted by the Governor of Colorado on May 10, 2000. We are publishing this rule without prior proposal because the Agency views this as a noncontroversial amendment and anticipates no adverse comments. However, in the “Proposed Rules” section of today's Federal Register publication, we are publishing a separate document that will serve as the proposal to approve the SIP revisions if adverse comments are filed. This rule will be effective November 13, 2001 without further notice unless the Agency receives adverse comments by October 11, 2001. If we receive adverse comments, then we will publish a timely withdrawal of the direct final rule, in the Federal Register, informing the public that the rule will not take effect. All public comments received will then be addressed in a subsequent final rule based on the proposed rule. We will not institute a second comment period on this action. Any parties interested in commenting must do so at this time. If no such comments are received, the public is advised that this rule will be effective on November 13, 2001, and no further action will be taken on the proposed rule. Please note that if we receive adverse comment on an amendment, paragraph, or section of this rule and if that provision may be severed from the remainder of the rule, we may adopt as final those provisions of the rule that are not the subject of an adverse comment.

V. Administrative Requirements

Under Executive Order 12866 (58 FR 51735, October 4, 1993), this action is not a “significant regulatory action” and therefore is not subject to review by the Office of Management and Budget. This action merely approves state law as meeting federal requirements and imposes no additional requirements beyond those imposed by state law. Accordingly, the Administrator certifies that this rule will not have a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.). Because this rule approves pre-existing requirements under state law and does not impose any additional enforceable duty beyond that required by state law, it does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Public Law 104-4). This rule also does not have a substantial direct effect on one or more Indian tribes, on the relationship between the Federal Government and Indian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian tribes, as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), nor will it have substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132 (64 FR 43255, August 10, 1999), because it merely approves a state rule implementing a federal standard, and does not alter the relationship or the distribution of power and responsibilities established in the Clean Air Act. This rule also is not subject to Executive Order 13045 (62 FR 19885, April 23, 1997), because it is not economically significant.

In reviewing SIP submissions, EPA's role is to approve state choices, provided that they meet the criteria of the Clean Air Act. In this context, in the absence of a prior existing requirement for the State to use voluntary consensus standards (VCS), EPA has no authority to disapprove a SIP submission for failure to use VCS. It would thus be inconsistent with applicable law for EPA, when it reviews a SIP submission, to use VCS in place of a SIP submission that otherwise satisfies the provisions of the Clean Air Act. Thus, the requirements of section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) do not apply. As required by section 3 of Executive Order 12988 (61 FR 4729, February 7, 1996), in issuing this rule, EPA has taken the necessary steps to eliminate drafting errors and ambiguity, minimize potential litigation, and provide a clear legal standard for affected conduct. EPA has complied with Executive Order 12630 (53 FR 8859, March 15, 1988) by examining the takings implications of the rule in accordance with the “Attorney General's Supplemental Guidelines for the Evaluation of Risk and Avoidance of Unanticipated Takings' issued under the executive order. This rule does not impose an information collection burden under the provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.).

The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, to each House of the Congress and to the Comptroller General of the United States. EPA will submit a report containing this rule and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the rule in the Federal Register. A major rule cannot take effect until 60 days after it is published in the Federal Register. This action is not a “major rule” as defined by 5 U.S.C. 804(2). This rule will be effective November 13, 2001 Start Printed Page 47086unless EPA receives adverse written comments by October 11, 2001.

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 November 13, 2001. 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).)
