Agency.

I. What is the Purpose of This Action?

    In this action, we are approving a revised maintenance plan for the 
Colorado Springs CO attainment/maintenance area, that is designed to 
keep the area in attainment for CO through 2010, and we're also 
approving changes to the State's Regulation No. 13 for the removal of 
the requirement for the implementation of the wintertime oxygenated 
fuels program in the Colorado Springs area.
    We approved the original CO redesignation request to attainment, a 
maintenance plan, and revisions to Regulation No. 13 (hereafter, Reg. 
13) for the Colorado Springs area on August 25, 1999 (see 64 FR 46279) 
which became effective on October 25, 1999.
    The Governor's May 10, 2000, submittal includes changes to the 
original maintenance plan that: revises the attainment year from 1993 
to 1990 and provides a new 1990 attainment year inventory; revises the 
maintenance demonstration with a revised 2010 projected emission 
inventory; revises Reg. 13 to eliminate the oxygenated gasoline program 
in El Paso County starting with the winter season of 2000-2001; revises 
the transportation CO emission budgets; and revises a portion of the 
contingency measures plan. We have determined that these changes are 
approvable as further described below.

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.
    The Colorado Air Quality Control Commission (AQCC) held a public 
hearing for the revised Colorado Springs Carbon Monoxide (CO) 
Maintenance Plan on February 17, 2000. The AQCC adopted the revised 
maintenance plan directly after the hearing. This SIP revision became 
State effective on April 30, 2000, and was submitted by the Governor to 
us on May 10, 2000.
    For the Regulation No. 13 revision, the AQCC held a public hearing 
to consider the changes to Regulation No. 13, that involved the 
elimination of the oxygenated gasoline program for El Paso County, on 
February 17, 2000. The AQCC adopted these changes directly after the 
February 17, 2000, public hearing. They became State effective on April 
30, 2000, and were also submitted to us on May 10, 2000.
    We have evaluated the Governor's submittal for the revised 
maintenance plan and changes to Regulation No. 13 and have determined 
that the State met the requirements for reasonable notice and public 
hearing under section 110(a)(2) of the CAA. We reviewed these SIP 
materials for conformance with the completeness criteria in 40 CFR part 
51, appendix V and determined that the submittals were administratively 
and technically complete. The Governor was advised of our completeness 
determination through a letter from Rebecca W. Hanmer, Acting Regional 
Administrator, dated August 7, 2000.

III. EPA's Evaluation of the Revised Maintenance Plan

    EPA has reviewed the State's revised maintenance plan for the 
Colorado Springs maintenance/attainment area and believes that approval 
is warranted. The following are the key aspects of this revision along 
with our evaluation of each:
    (a) The State changed the attainment year from 1993 to 1990 and 
provided a new 1990 emissions inventory.
    This is acceptable as the Colorado Springs area was attaining the 
CO NAAQS in 1990 (based on data from 1990 and 1991 which are archived 
in our Aerometric Information and

[[Page 80780]]

Retrieval System--AIRS) and this conforms to our September 4, 1992, 
redesignation guidance memorandum, signed by John Calcagni, Director of 
the Air Quality Management Division, entitled ``Procedures for 
Processing Requests to Redesignate Areas to Attainment'' (hereafter the 
``Calcagni memorandum''). Further, the area must show continuous 
attainment of the CO NAAQS from 1990 to present. We have reviewed the 
air quality data in AIRS from 1990 to present and have determined that 
the Colorado Springs area has not violated the CO standard and 
continues to demonstrate attainment.
    (b) The State revised the projected emission inventories, out to 
2010, and continues to demonstrate maintenance for the Colorado Springs 
area.
    Revised emission projections for the years 2001, 2002, 2005, and 
2010 (we note that 2015 and 2020 are also included for conformity 
purposes) that include all source categories (point, area, non-road, 
and on-road) and reflect the elimination of the oxygenated fuels 
program are presented in ``Table 3. Carbon Monoxide Emissions for 
Future Years in Colorado Springs without the Oxygenated Fuels Program'' 
of the revised maintenance plan and are archived below. All emission 
calculations and assumptions are provided in the State's Technical 
Support Document (TSD). As shown in the maintenance plan's Table 3. and 
in our Table III-1 below, emissions for all future projected year 
inventories are less than the 1990 levels. Therefore, the area 
continues to demonstrate maintenance for the CO standard.

                                                                       1990     2001     2002     2005     2010

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

    (c) The State has modified Regulation No. 13 to eliminate the 
Oxygenated Fuels Program for El Paso County and the Colorado Springs 
area.
    The State performed an analysis and determined that the oxygenated 
fuels program could be eliminated for the Colorado Springs area without 
jeopardizing maintenance of the CO NAAQS. This analysis was performed 
using EPA's MOBILE5b emission factor model and the latest 
transportation and planning data from the Pike's Peak Area Council of 
Governments (PPACG) 2020 transportation plan. The methodology and 
analysis were reviewed by us and we have determined they are 
acceptable. The results of the modeling were presented in the revised 
maintenance plan's ``Table 1.,'' ``Table 2.,'' and ``Table 3'' and are 
also included in our Table III-1 above. Based on our review of the 
State's analysis, we agree that the Colorado Springs area continues to 
demonstrate maintenance of the CO NAAQS and approve the elimination of 
the oxygenated fuels program for El Paso County and the Colorado 
Springs area.
    (d) The State modified the Contingency Provisions section of the 
maintenance plan.
    With the elimination of the oxygenated fuels program for the 
Colorado Springs area, the State revised the contingency measures list 
in section ``E. Contingency Provisions'' to now contain the 
reinstatement of the 2.7% oxygenated fuels program as a contingency 
measure that could be implemented should the Colorado Springs area 
violate the CO NAAQS. Also, the State removed the prior nonattainment 
area regulatory requirement that an enhanced inspection and maintenance 
program be a pre-approved contingency measure. An enhanced inspection 
and maintenance program now appears on the same list as the 2.7% 
oxygenated fuels program as possible contingency measures for 
consideration, adoption, and implementation should a violation of the 
CO NAAQS occur. We agree with the above revisions to the ``Contingency 
Provisions'' section of the maintenance plan.

IV. EPA's Evaluation of the Transportation Conformity Requirements

    One key provision of our conformity regulation requires a 
demonstration that emissions from the transportation plan and 
Transportation Improvement Program are consistent with the emissions 
budgets in the SIP (40 CFR 93.118 and 93.124). The emissions budget is 
defined as the level of mobile source emissions relied upon in the 
attainment or maintenance demonstration to maintain compliance with the 
NAAQS in the nonattainment or maintenance area. The rule's requirements 
and EPA's policy on emissions budgets are found in the preamble to the 
November 24, 1993, transportation conformity rule (58 FR 62193-62196) 
and in the sections of the rule referenced above. Section C. of the 
revised Colorado Springs maintenance plan describes an emissions budget 
for on-road mobile sources. The revised section C. now states:

    For the Colorado Springs attainment/maintenance area, the 
emissions budget is for the period 2001 and beyond and this budget 
utilizes the ``margin of safety'' provisions of EPA's transportation 
conformity rule. The rule indicates that where projected emissions 
from all sources are less than the amount demonstrating attainment, 
which is the case for the Colorado Springs area, the SIP may 
explicitly quantify the safety margin and include some of all of it 
in the motor vehicle emissions budget for purposes of conformity. 
When the calculations are made, there are different margins of 
safety for each interim year between 2001 and 2010, which could 
result in the establishment of different emissions budgets for each 
year. Because this is not practical, an emissions budget slightly 
less than the lowest potential emissions budget is adopted for all 
future years.''

    The State then performed calculations (in tons per day, abbreviated 
as ``tpd'') for each of the interim years such as in the example below 
for 2001:

    380 tpd (1990 total emissions)--307 tpd (2001 total emissions) = 
73 tpd (2001 margin of safety); 73 tpd + 209 tpd (2001 mobile 
emissions) = 282 tpd (potential emission budget for 2001)

    The State then did the same calculations for the other interim 
years and came up with potential emission budgets of; 281 tpd for 2002, 
280 tpd for 2005, and 280 tpd for 2010. In order to allow for 
uncertainties in non-mobile source emissions, and because all interim 
years' emissions between 2001 and 2010 were not determined, the State 
took the lowest potential emissions budget of 280 tpd and further 
reduced this to 270 tpd to allow for potential variations in emissions 
and to stay below the 1990 total attainment emission level of 380 tpd. 
The State then set this 270 tpd on-road mobile emissions budget for 
2001 and beyond.

[[Page 80781]]

We agree with the State's calculations and allocation of the margin of 
safety, and therefore, we are approving this 270 tpd mobile sources 
emission budget for 2001 and beyond.
    This 270 tpd budget was then adopted into section V.A.4.b. of the 
Colorado AQCC's Ambient Air Quality Standards regulation (5 CCR 1001-
14); however, the emissions budget definition in the table on page 
18.01 of the Colorado Ambient Air Quality Standards regulation (5 CCR 
1001-14) conflicts with the language in section C. of the maintenance 
plan and is internally inconsistent. Section C. of the maintenance plan 
states that the 270 tpd emission budget applies to 2001 and beyond; the 
table on page 18.01 of 5 CCR 1001-14 indicates that the emissions 
budget is 280 tpd in 2010 and beyond. Our interpretation, based on the 
language of the maintenance plan and our conformity rule, is that the 
maintenance plan's 270 tpd emission budget applies starting in 2001 and 
for all following years, superseding the incorrect language in 5 CCR 
1001-14.

V. EPA's Evaluation of the Regulation No. 13 Revisions

    Colorado's Regulation No. 13 is entitled ``Oxygenated Fuels 
Program.'' The purpose of revisions that were adopted by the AQCC on 
February 17, 2000, and submitted to us by the Governor on May 10, 2000, 
was to eliminate the oxygenated fuels program for El Paso County and 
the Colorado Springs area. EPA is allowed to approve this elimination 
of the oxygenated fuels program for El Paso County and the Colorado 
Springs area based on section 211(m)(6) of the CAA which states:

    ATTAINMENT AREAS--Nothing in this subsection shall be 
interpreted as requiring an oxygenated gasoline program in an area 
which is in attainment for carbon monoxide, except that in a carbon 
monoxide nonattainment area which is redesignated as attainment for 
carbon monoxide, the requirements of this subsection shall remain in 
effect to the extent such program is necessary to maintain such 
standard thereafter in the area. The State has satisfied the above 
requirements of section 211(m)(6) as follows:

    (a) The Colorado Springs area is in attainment for the CO NAAQS. 
EPA approved the Colorado Springs CO redesignation to attainment on 
August 25, 1999 (see 64 FR 46279, effective October 25, 1999). In 
addition, ambient air quality that have been archived in AIRS show that 
the Colorado Springs area has been in attainment for the CO NAAQS 
beginning with the period of 1990-1991 and the area has been in 
attainment for the CO NAAQS from that time to the present.
    (b) The State has provided an adequate demonstration showing that 
the oxygenated fuels program is not needed to maintain the CO NAAQS for 
the Colorado Springs attainment area. This requirement was addressed 
with the State's revised maintenance plan for the Colorado Springs 
area. As presented in section ``B. Emission Inventories and Maintenance 
Demonstration'' of the revised maintenance plan, the State used EPA's 
MOBILE5b emission factor model to calculate mobile source emissions, 
without an oxygenated fuels program, for 2001, 2002, 2005, and 2010. 
For each projected year, mobile source emissions were less than the 
1990 attainment year levels. When mobile source emissions were added to 
the other source categories for 2001, 2002, 2005, and 2010, total 
emissions for each year were still well below the 1990 attainment year 
levels. Therefore, elimination of the oxygenated fuels program will not 
interfere with continued maintenance of the CO NAAQS. In addition to 
the 1990 and 2010 region-wide inventories, the State prepared a 1990 
and 2010 gridded emission inventory and evaluated projected growth in 
CO emissions in each grid cell. This assessment also indicated that the 
CO NAAQS would be maintained without an oxygenated fuels program.
    Based on the above, the State concluded that the revisions to 
Regulation No. 13, to eliminate the oxygenated fuels program, would not 
jeopardize the revised maintenance plan's demonstration of maintenance 
for the CO NAAQS. We agree with the State's analysis provided in 
section ``B.'' of the revised maintenance plan and as further supported 
in the State's TSD. Therefore, we do not believe that the elimination 
of the oxygenated fuels program in El Paso County and the Colorado 
Springs area will impact the CO maintenance demonstration for the area.
    In consideration of above, we have determined that we can approve 
the February 17, 2000, revisions to Regulation No. 13 as meeting the 
requirements of section 211(m)(6) of the CAA.
    As noted previously, the revisions to Regulation No. 13 were 
adopted by the AQCC directly after a public hearing on February 17, 
2000, became State effective on April 30, 2000, and were submitted to 
us by the Governor on May 10, 2000.

VI. Final Action

    In this action, EPA is approving the revised Colorado Springs 
carbon monoxide maintenance plan and the revisions to Regulation No. 
13.
    EPA is publishing this action without prior proposal because the 
Agency views this as a noncontroversial amendment and anticipates no 
adverse comments. However, in the proposed rules section of this 
Federal Register publication, we are publishing a separate document 
that will serve as the proposal to approve the SIP revision should 
adverse comments be filed. This rule will be effective February 20, 
2001 without further notice unless the Agency receives adverse comments 
by January 22, 2001.
    If EPA receives such comments, then we will publish a timely 
withdrawal of the direct final rule 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. The 
EPA will not institute a second comment period on this rule. Any 
parties interested in commenting on this rule should do so at this 
time. If no such comments are received, the public is advised that this 
rule will be effective on February 20, 2001 and no further action will 
be taken on the proposed rule.

Administrative Requirements

(a) Executive Order 12866

    The Office of Management and Budget (OMB) has exempted this 
regulatory action from Executive Order 12866, entitled ``Regulatory 
Planning and Review.''

(b) Executive Order 12875: Enhancing the Intergovernmental Partnership

    Under Executive Order 12875, EPA may not issue a regulation that is 
not required by statute and that creates a mandate upon a state, local, 
or tribal government, unless the Federal government provides the funds 
necessary to pay the direct compliance costs incurred by those 
governments, or EPA consults with those governments. If EPA complies by 
consulting, Executive Order 12875 requires EPA to provide to the Office 
of Management and Budget a description of the extent of EPA's prior 
consultation with representatives of affected state, local, and tribal 
governments, the nature of their concerns, copies of any written 
communications from the governments, and a statement supporting the 
need to issue the regulation. In addition, Executive Order 12875 
requires EPA to develop an effective process permitting

[[Page 80782]]

elected officials and other representatives of state, local, and tribal 
governments ``to provide meaningful and timely input in the development 
of regulatory proposals containing significant unfunded mandates.''
    Today's rule does not create a mandate on state, local, or tribal 
governments. The rule does not impose any enforceable duties on state, 
local, or tribal governments. Accordingly, the requirements of section 
1(a) of Executive Order 12875 do not apply to this rule.

(c) Executive Order 13045

    Executive Order 13045, Protection of Children from Environmental 
Health Risks and Safety Risks (62 FR 19885, April 23, 1997), applies to 
any rule that: (1) is determined to be ``economically significant'' as 
defined under Executive Order 12866, and (2) concerns an environmental 
health or safety risk that EPA has reason to believe may have a 
disproportionate effect on children. If the regulatory action meets 
both criteria, the Agency must evaluate the environmental health and 
safety effects of the planned rule on children, and explain why the 
planned regulation is preferable to other potentially effective and 
reasonably feasible alternatives considered by the Agency.
    This rule is not subject to Executive Order 13045 because it does 
not involve decisions intended to mitigate environmental health or 
safety risks.

(d) Executive Order 13084: Consultation and Coordination With Indian 
Tribal Governments

    Under Executive Order 13084, EPA may not issue a regulation that is 
not required by statute, that significantly affects or uniquely affects 
the communities of Indian tribal governments, and that imposes 
substantial direct compliance costs on those communities, unless the 
Federal government provides the funds necessary to pay the direct 
compliance costs incurred by the tribal governments, or EPA consults 
with those governments. If EPA complies by consulting, Executive Order 
12084 requires EPA to provide to the Office of Management and Budget, 
in a separately identified section of the preamble to the rule, a 
description of the extent of EPA's prior consultation with 
representatives of affected tribal governments, a summary of the nature 
of their concerns, and a statement supporting the need to issue the 
regulation. In addition, Executive Order 13084 requires EPA to develop 
an effective process permitting elected officials and other 
representatives of Indian tribal governments ``to provide meaningful 
and timely input in the development of regulatory policies on matters 
that significantly or uniquely affect their communities.''
    Today's rule does not significantly or uniquely affect the 
communities of Indian tribal governments. Accordingly, the requirements 
of section 3(b) of Executive Order 13084 do not apply to this rule.

(e) Regulatory Flexibility Act

    The Regulatory Flexibility Act (RFA) generally requires an agency 
to conduct a regulatory flexibility analysis of any rule subject to 
notice and comment rulemaking requirements unless the agency certifies 
that the rule will not have a significant economic impact on a 
substantial number of small entities. Small entities include small 
businesses, small not-for-profit enterprises, and small governmental 
jurisdictions. This final rule will not have a significant impact on a 
substantial number of small entities because SIP approvals under 
section 110 and subchapter I, part D of the Clean Air Act do not create 
any new requirements, but simply approve requirements that the State is 
already imposing. Therefore, because the Federal SIP approval does not 
create any new requirements, I certify that this action will not have a 
significant economic impact on a substantial number of small entities. 
Moreover, due to the nature of the Federal-State relationship under the 
Clean Air Act, preparation of a flexibility analysis would constitute 
Federal inquiry into the economic reasonableness of State action. The 
Clean Air Act forbids EPA to base its actions concerning SIPs on such 
grounds. Union Electric Co. v. U.S. EPA, 427 U.S. 246, 255-66 (1976); 
42 U.S.C. 7410(a)(2). Therefore, I certify this rule will not affect a 
substantial number of small entities.

(f) Unfunded Mandates

    Under section 202 of the Unfunded Mandates Reform Act of 1995 
(``Unfunded Mandates Act''), signed into law on March 22, 1995, EPA 
must prepare a budgetary impact statement to accompany any proposed or 
final rule that includes a Federal mandate that may result in estimated 
costs to State, local, or tribal governments in the aggregate, or to 
the private sector, of $100 million or more. Under section 205, EPA 
must select the most cost-effective and least burdensome alternative 
that achieves the objectives of the rule and is consistent with 
statutory requirements. Section 203 requires EPA to establish a plan 
for informing and advising any small governments that may be 
significantly or uniquely impacted by the rule.
    EPA has determined that the approval action promulgated does not 
include a Federal mandate that may result in estimated costs of $100 
million or more to either State, local, or tribal governments in the 
aggregate, or to the private sector. This Federal action approves pre-
existing requirements under State or local law, and imposes no new 
requirements. Accordingly, no additional costs to State, local, or 
tribal governments, or to the private sector, will result from this 
action.

(g) Submission to Congress and the Comptroller General

    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 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 the publication of the rule in the Federal Register. This rule is 
not a ``major rule'' as defined by 5 U.S.C. 804(2).

(h) Petitions for Judicial Review

    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 February 20, 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).)
