Approval and Promulgation of Implementation Plans; New Mexico; 
Revision to Motor Vehicle Emission Budgets in Bernalillo County, New 
Mexico Carbon Monoxide Air Quality Maintenance Plan Using MOBILE6

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

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

SUMMARY: The EPA is taking direct final action approving the State 
Implementation Plan (SIP) revisions for Bernalillo County, New Mexico, 
which is a carbon monoxide maintenance area. This SIP revision was 
submitted to EPA by the Governor of New Mexico on May 15, 2003. More 
specifically, EPA is approving the county's revised Motor Vehicle 
Emissions Budget (MVEB) for carbon monoxide (CO) for 1996, 1999, 2002, 
2005 and 2006. This budget was developed using EPA's latest emissions

modeling program, MOBILE6. This submittal updates the maintenance plan 
by establishing new transportation conformity MVEBs for use by the Mid-
Region Council of Governments, the area's Metropolitan Planning 
Organization (MPO). These budgets will continue to maintain the total 
on-road mobile source emissions for the area at or below the attainment 
level for the CO National Ambient Air Quality Standard (NAAQS).

DATES: This rule is effective on November 24, 2003 without further 
notice, unless EPA receives adverse comment by November 10, 2003. If 
EPA receives such comment, EPA will publish a timely withdrawal in the 
Federal Register informing the public that this rule will not take 
effect.

ADDRESSES: Written comments on this action should be addressed to Mr. 
Thomas H. Diggs, Chief, Air Planning Section (6PD-L), at the EPA Region

I. Background

    In 1990, the City of Albuquerque/Bernalillo County (Albuquerque) in 
New Mexico had a CO design value of 11.1 parts per million, exceeding 
the National Ambient Air Quality Standard (NAAQS) of 9 parts per 
million (8-hour average basis). Consequently, Albuquerque was 
classified as a moderate nonattainment area for CO under the Clean Air 
Act (the Act). As required by the Act, on November 5, 1992, New Mexico 
submitted for EPA approval a revision to the SIP to address 
Albuquerque's CO nonattainment.
    Different parts of the November 1992 SIP submittal were approved at 
different times, with approval of all aspects completed in June of 
1996.
    Air quality data in the Albuquerque area showed no violations of 
the CO NAAQS between 1992 and 1995, meeting the first criterion for 
redesignation. On April 14, 1995, New Mexico submitted a request that 
Albuquerque be redesignated to attainment for CO. EPA proposed approval 
of this request on February 16, 1996. This approval was made effective 
on July 15, 1996.
    The Act also requires a periodic inventory of all emissions from 
area, mobile, and stationary sources. The 1993 emission inventory found 
the following CO emissions levels, in tons per day: Stationary sources, 
3.18; area sources, 111.60; On-road mobile sources, 274.16; and nonroad 
mobile sources, 45.74. Total CO emissions were 434.69 tons per day.
    This inventory was further updated in 1996. This updated inventory 
reflected the following CO emissions levels, in tons per day: On-road 
mobile sources, 266.99; nonroad mobile sources, 50.90; area sources, 
67.19; and stationary sources, 3.92. Total CO emissions were 
inventoried at 389.0 tons per day.
    The Albuquerque/Bernalillo County area submitted further revisions 
to its maintenance plan emissions budgets on February 4, 1999, using 
the MOBILE5 emission factor modeling program. These revisions, for 
years 1996-2006, increased the budgets for mobile and stationary source 
emissions but decreased the budget for area source emissions, resulting 
in an overall decrease in budgeted emissions. These revisions also 
established a 2010 emissions budget. A direct final rule approving 
these revisions was published December 20, 1999. However, adverse 
comments were received and the direct final approval was withdrawn. 
After addressing the comments received, the EPA gave final approval to 
the budget revisions for 1996-2010 on May 24, 2000 (65 FR 33455). The 
revised MVEBs are as follows, in tons of CO emissions per day: 1996, 
266.99; 1999, 229.09; 2002, 209.1; 2005, 205.67; 2006, 205.86; and 
2010, 222.46.

II. What Is MOBILE6?

    MOBILE6 is the latest in a series of EPA emissions factor models 
for estimating pollution from on-road motor vehicles in states outside 
of California and represents the first major update of the preexisting 
MOBILE model since 1993. The release of this model was announced in a 
Federal Register notice published on January 29, 2002 (67 FR 4254). 
This date marks the beginning of the two-year grace period, after which 
all areas must use MOBILE6 for emissions factor modeling for 
transportation conformity purposes. MOBILE6 calculates emissions of 
carbon monoxide and other pollutants from passenger cars, motorcycles, 
buses, and light-duty and heavy-duty trucks. The model accounts for the 
emission impacts of factors such as changes in vehicle emissions 
standards, changes in vehicle populations, and variation in local 
conditions such as temperature, humidity, fuel quality, and air quality 
programs.
    MOBILE6 is used to calculate current and future inventories of 
motor vehicle emissions at the national and local level. These 
inventories are used to make decisions about air pollution policies and 
programs at the local, state and national level. Inventories based on 
MOBILE6 are also used to meet the federal Clean Air Act's SIP and 
transportation conformity requirements.
    The MOBILE model was first developed in 1978 and MOBILE6 is the 
first major update of the model since 1993. It has been updated many 
times to reflect changes in vehicle fleet composition and fuels, to 
incorporate EPA's growing understanding of vehicle emissions, and to 
cover new emissions regulations and modeling needs.

III. Analysis of the State's Submittal

A. Why Were Updated Carbon Monoxide Budgets Established?

    The existing MVEBs for CO were last modified through a SIP revision 
approved and made effective by EPA on May 24, 2000 (65 FR 33455).
    To address and accommodate the release of MOBILE6 as the latest 
EPA-approved emissions factor model, the

[[Page 58278]]

governor of New Mexico submitted a SIP revision to EPA on May 15, 2003. 
The MVEBs contained in the current CO maintenance plan were calculated 
with a previous emissions factor model, MOBILE5a. This submittal 
revises the Motor Vehicle Emissions Budgets for the years 1996, 1999, 
2002, 2005 and 2006 using MOBILE6. Note that only the MVEBs are being 
revised using the MOBILE6 model; budgets for the other source 
categories will remain unchanged as the MOBILE6 model does not affect 
these categories. However, changes in the estimated amount of CO 
produced by the on-road mobile source category will affect the CO 
baseline level and the CO totals by year. Therefore, the baseline level 
and amounts of total CO by year will be revised in response to the 
MOBILE6 analysis.
    The EPA guidance document, Policy Guidance on the Use of MOBILE6 
for SIP Development and Transportation Conformity, issued by John Seitz 
on January 18, 2002 (``MOBILE6 Guidance''), states that nonattainment 
and maintenance areas may forgo the requirement to update all planning 
assumptions when updating the MVEBs with MOBILE6, if the area can 
demonstrate that these assumptions have not changed since the last 
budget revision. For CO, population is the most important assumption 
underlying the CO forecasts as it has a direct impact on the number of 
miles driven. Comparing the Albuquerque/Bernalillo County population 
figure for the year 2000 used in the last SIP revision (556,248) to the 
population for the same area recorded in the 2000 Census (556,678) 
results in a difference of 0.077%, less than 1%. Because the estimated 
figure matches so closely with the actual census count, the requirement 
that the latest planning assumptions continue to be valid is met and 
this SIP revision continues to use these estimates. Additionally, work 
has already begun on the required second ten-year maintenance plan, due 
to EPA in June of 2004. With this expected submission, the MPO will 
update the emissions inventory in its entirety with the latest planning 
assumptions and demographic data.

B. Recalculating the Motor Vehicle Emissions Budget With MOBILE6

    Because of the significant difference in modeling results between 
the previous version of the emissions factor model, MOBILE5a, and the 
updated version, MOBILE6, the on-road mobile source category in the 
emissions inventory was recalculated for all years represented in the 
ten-year maintenance time frame of the SIP using MOBILE6. This 
inventory provides the basis for determining the MVEBs for CO. The 
MVEBs are the same as the total estimated CO, in tons per day, for the 
on-road mobile source category in the emissions inventory. For all 
years beyond 2006 (the last modeled year), the MVEB will be held at the 
2006 level.
    The table below compares the existing MVEBs with the revised MVEBs 
submitted with this SIP revision.

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

    For all budget years, MOBILE6 estimates a greater production of CO 
than MOBILE5a. Although the MOBILE6 emissions are estimated to be 
higher than that previously predicted by MOBILE5a, the model still 
demonstrates greater relative emissions reductions benefits. Recall 
that only the budget estimates for on-road mobile source emissions (the 
MVEBs) are being revised with the MOBILE6 model. Changes in the MVEBs 
will, however, affect the overall CO budgets and CO baseline level even 
though the amount of CO in the other source categories (nonroad mobile, 
area, and stationary) will remain unchanged. The MOBILE6 Guidance 
provides that nonattainment and maintenance areas may revise the on-
road mobile emissions inventory and MVEBs without revising the entire 
SIP and other emission inventory categories, if the SIP continues to 
demonstrate maintenance of the standard when the MOBILE5a-based on-road 
mobile source inventories are replaced with MOBILE6 inventories. To 
demonstrate this, the following table shows the entire emission 
inventory, with the on-road mobile source category replaced with the 
resultant MOBILE6-derived estimates. The revised MVEBs are shown, along 
with the currently approved inventories from the other source 
categories. These inventories were approved in a revision to the CO 
maintenance plan on May 24, 2000 (65 FR 33455).

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

    The 1996 figure found in the revised total column, 538.32 tpd, is 
the new CO baseline level as calculated with MOBILE6. The original 
baseline level, as approved on May 24, 2000, was 389.0 tpd. This level 
represents the amount of CO, in tons per day, which may be emitted by 
all sources and still allow the Albuquerque/Bernalillo County area to 
be in attainment of the NAAQS. Essentially, this baseline represents 
the ``cap'' of emissions from all sources. The results of MOBILE6 
modeling, which raises the baseline level, indicates that the initial 
CO baseline, as determined using MOBILE5a, was set too low. This new 
analysis indicates that the Albuquerque/Bernalillo County area actually 
had a larger amount of CO in the airshed in 1996, yet still met the 
NAAQS. The following table illustrates the relative gain in emissions 
reductions when comparing the MOBILE5a-derived estimates with those of 
MOBILE6.

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

    The greater decline in emissions seen with MOBILE6 between 1996 and 
2006 can be attributed to the sensitivity of the model to local 
parameters incorporated into MOBILE6 and the control programs in place 
in Albuquerque/Bernalillo County. So, although the emissions cap is 
higher with MOBILE6, that difference is due to the sensitivity of the 
newer model.
    MOBILE6 offers a more robust and accurate estimate of emissions 
than prior versions of the model. Comparing just the MOBILE5a and 
MOBILE6 on-road mobile source estimates indicates that MOBILE6 shows a 
relative reduction in CO emissions that is approximately twice as much 
as that seen with MOBILE5a.

IV. Final Action

    We have evaluated the State's submittal and have determined that it 
meets the applicable requirements of the Act and EPA regulations, and 
is consistent with EPA policy. Therefore, we are approving 
Albuquerque's request to revise the MVEBs in its carbon monoxide 
maintenance SIP using MOBILE6, EPA's latest emission factor modeling 
program.
    The EPA is publishing this rule without prior proposal because we 
view this as a noncontroversial amendment and anticipate 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 if adverse comments 
are received. This rule will be effective on November 24, 2003 without 
further notice unless we receive adverse comment by November 10, 2003. 
If we receive adverse comments, we will publish a timely withdrawal in 
the Federal Register informing the public that the rule will not take 
effect. We will address all public comments 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. 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. Statutory and Executive Order Reviews

    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. For this 
reason, this action is also not subject to Executive Order 13211, 
``Actions Concerning Regulations That Significantly Affect Energy 
Supply, Distribution, or Use'' (66 FR 28355, May 22, 2001). 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 (Pub. L. 104-4).
    This rule also does not have tribal implications because it will 
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). This action also does not have Federalism 
implications because it does not 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). This action 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 
``Protection of Children from Environmental Health Risks and Safety 
Risks'' (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. 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).
    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 December 8, 2003. 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).)
