Monoxide Maintenance Plan and
Approval of Related Revisions
Environmental Protection
Agency (EPA).
ACTION: Direct final rule.
AGENCY:
SUMMARY: EPA is taking direct final
action approving State Implementation
Plan (SIP) revisions submitted by the
State of Utah. On November 29, 2004,
the Governor of Utah submitted
revisions to Utah’s Rule R307–110–12,
‘‘Section IX, Control Measures for Area
and Point Sources, Part C, Carbon
Monoxide,’’ which incorporates a
revised maintenance plan for the Ogden
carbon monoxide (CO) maintenance
area for the CO National Ambient Air
Quality Standard (NAAQS). The revised
maintenance plan contains revised
transportation conformity budgets for
the years 2005 and 2021. In addition,
the Governor submitted revisions to
Utah’s Rule R307–110–35, ‘‘Section X,
Vehicle Inspection and Maintenance
Program, Part E, Weber County,’’ which
incorporates a revised vehicle
inspection and maintenance program for
Weber County. In this action, EPA is
approving the Ogden City CO revised
maintenance plan, the revised
transportation conformity budgets, the
revised vehicle inspection and
maintenance program for Weber County,
and the revisions to rules R307–110–12
and R307–110–35. This action is being
taken under section 110 of the Clean Air
Act.
DATES: This rule is effective on
November 14, 2005 without further
notice, unless EPA receives adverse
comment by October 14, 2005. If
adverse comment is received, EPA will
publish a timely withdrawal of the
direct final rule in the Federal Register
informing the public that the rule will
not take effect.

II. What Is the Purpose of This Action?
In this action, we are approving a
revised maintenance plan for the Ogden
CO attainment/maintenance area that is
designed to keep the area in attainment
PO 00000
Frm 00034
Fmt 4700
Sfmt 4700
for CO through 2021, we’re approving
revised transportation conformity motor
vehicle emissions budgets (MVEBs), and
we’re approving revisions to the vehicle
inspection and maintenance program for
Weber County. We are also approving
revisions to Utah’s Rule R307–110–12,
‘‘Section IX, Control Measures for Area
and Point Sources, Part C, Carbon
Monoxide,’’ and Rule R307–110–35,
‘‘Section X, Vehicle Inspection and
Maintenance Program, Part E, Weber
County,’’ which merely incorporate the
State’s SIP revisions to the Ogden CO
maintenance plan and the vehicle
inspection and maintenance program for
Weber County, respectively.
We approved the original CO
redesignation to attainment and
maintenance plan for the Ogden area on
March 9, 2001 (see 66 FR 14078).
The original Ogden CO maintenance
plan that we approved on March 9, 2001
(hereafter March 9, 2001 maintenance
plan) utilized the then applicable EPA
mobile sources emission factor model,
MOBILE5a. On January 18, 2002, we
issued policy guidance for States and
local areas to use to develop SIP
revisions using the new, updated
version of the model, MOBILE6. The
policy guidance was entitled ‘‘Policy
Guidance on the Use of MOBILE6 for
SIP Development and Transportation
Conformity’’ (hereafter, January 18, 2002
MOBILE6 policy). On November 12,
2002, EPA’s Office of Transportation
and Air Quality (OTAQ) issued an
updated version of the MOBILE6 model,
MOBILE6.2, and notified Federal, State,
and Local agency users of the model’s
availability. MOBILE6.2 contained
additional updates for air toxics and
particulate matter. However, the CO
emission factors were essentially the
same as in the MOBILE6 version of the
model.
For the revised maintenance plan, the
State recalculated the CO emissions for
the 1992 attainment year, projected
emission inventories for 2004, 2005,
2008, 2011, 2014, 2017, 2020, and 2021,
and calculated all the mobile source
emissions using MOBILE6.2. Based on
projected significant mobile source
emission reductions for the interim
years between 2005 and 2021, the
State’s revised maintenance
demonstration is also able to
accommodate the relaxation of certain
provisions for newer vehicles in the
Weber County Vehicle Inspection and
Maintenance (I/M) Program while
continuing to demonstrate maintenance
of the CO NAAQS. Thus, the State has
asked us to approve a revision to
‘‘Vehicle Inspection and Maintenance
Program, Weber County’’ (hereafter
referred to as ‘‘Weber County I/M
E:\FR\FM\14SER1.SGM
14SER1
Federal Register / Vol. 70, No. 177 / Wednesday, September 14, 2005 / Rules and Regulations
program’’ or ‘‘I/M program’’)that allows
vehicles less than six years old to be
inspected every other year instead of
annually. The State calculated a CO
MVEB for 2005 and applied a selected
amount of the available safety margin to
the 2005 transportation conformity
MVEB. The State calculated a CO MVEB
for 2021 and beyond and also applied a
selected amount of the available safety
margin to the 2021 and beyond
transportation conformity MVEB. We
have determined that all the revisions
noted above are Federally-approvable,
as described further below.
III. 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 Utah Air Quality Board (UAQB)
held a public hearing for the revised
Ogden CO maintenance plan, the
revised Weber County vehicle
inspection and maintenance program,
and the revisions to Rule R307–110–12
and Rule R307–110–35 on September
22, 2004. The revised plan elements and
rules were adopted by the UAQB on
November 3, 2004. The revised CO
maintenance plan and Rule R307–110–
12 became State effective on January 4,
2005 and the revised vehicle inspection
and maintenance program and Rule
R307–110–35 became State effective on
November 4, 2004. The Governor
submitted these SIP revisions to us on
November 29, 2004. Additional
administrative materials were submitted
to us by the State on March 3, 2005.
We have evaluated the Governor’s
submittal for these SIP revisions and
have determined that the State met the
requirements for reasonable notice and
public hearing under section 110(a)(2)
of the CAA. As required by section
110(k)(1)(B) 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. Our completeness
determination was sent on March 22,
2005, through a letter from Robert E.
Roberts, Regional Administrator, to
Governor Jon Huntsman Jr.
IV. EPA’s Evaluation of the Revised
Maintenance Plan
EPA has reviewed the State’s revised
maintenance plan for the Ogden
attainment/maintenance 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 has air quality data that
show continuous attainment of the CO
NAAQS.
As described in 40 CFR 50.8, the
national primary ambient air quality
standard for carbon monoxide is 9 parts
per million (10 milligrams per cubic
meter) for an 8-hour average
concentration not to be exceeded more
than once per year. 40 CFR 50.8
continues by stating that the levels of
CO in the ambient air shall be measured
by a reference method based on 40 CFR
part 50, appendix C and designated in
accordance with 40 CFR part 53 or an
54269
equivalent method designated in
accordance with 40 CFR part 53. The
March 9, 2001 maintenance plan relied
on ambient air quality data from 1992
through 1999. In our consideration of
the revised Ogden maintenance plan,
submitted by the Governor on
November 29, 2004, we reviewed
ambient air quality data from 1992
through 2004. The Ogden area shows
continuous attainment of the CO
NAAQS from 1992 to present. All of the
above-referenced air quality data are
archived in our Air Quality System
(AQS).
(b) Using the MOBILE6.2 emission
factor model, the State revised the
attainment year inventory (1992) and
provided projected emissions
inventories for the years 2004, 2005,
2008, 2011, 2014, 2017, 2020, and 2021.
The revised maintenance plan that the
Governor submitted on November 29,
2004, includes comprehensive
inventories of CO emissions for the
Ogden area. These inventories include
emissions from stationary point sources,
area sources, non-road mobile sources,
and on-road mobile sources. More
detailed descriptions of the revised 1992
attainment year inventory, and the
projected emissions inventories for
2004, 2005, 2008, 2011, 2014, 2017,
2020, and 2021, are documented in the
maintenance plan in section IX.C.8.b
entitled ‘‘Emission Inventories and
Maintenance Demonstration,’’ and in
the State’s Technical Support Document
(TSD). The State’s submittal contains
emission inventory information that was
prepared in accordance with EPA
guidance. Summary emission figures
from the 1992 attainment year and the
projected years are provided in Table
IV–1 below.

Federal Register / Vol. 70, No. 177 / Wednesday, September 14, 2005 / Rules and Regulations
The revised mobile source emissions
show that the largest change from the
original March 9, 2001 maintenance
plan is primarily due to the use of
MOBILE6.2 instead of MOBILE5a. The
MOBILE6.2 modeling information is
contained in the State’s TSD (see
‘‘Mobile Source 1992 Base Year
Inventory Using MOBILE6.2,’’ pages
3.b.v-1 through 3.b.v-5; and ‘‘Mobile
Source Projection Year Inventories
Using MOBILE6.2,’’ pages 4.e-1 through
4.e-3) and on a compact disk produced
by the State (see ‘‘Supplemental Mobile
Source Data (CD–ROM),’’ section 2.d.).
A copy of the State’s compact disk is
available upon request to EPA. The
compact disk contains much of the
modeling data, MOBILE6.2 input-output
files, fleet makeup, MOBILE6.2 input
parameters, and other information, and
is included with the docket for this
action. Other revisions to the mobile
sources category resulted from revised
vehicle miles traveled (VMT) estimates
provided to the State by the Wasatch
Front Regional Council (WFRC) which
is the metropolitan planning
organization (MPO) for the Ogden area.
In summary, the revised maintenance
plan and State TSD contain detailed
emission inventory information that was
prepared in accordance with EPA
guidance and is acceptable to EPA.
(c) The State revised the March 9,
2001 Ogden maintenance plan.
The March 9, 2001 CO maintenance
plan utilized the then applicable EPA
mobile sources emission factor model,
MOBILE5a. On January 18, 2002, we
issued policy guidance for States and
local areas to use to develop SIP
revisions using the updated version of
the model, MOBILE6. The policy
guidance was entitled ‘‘Policy Guidance
on the Use of MOBILE6 for SIP
Development and Transportation
Conformity’’ (hereafter, January 18, 2002
MOBILE6 policy). Additional policy
guidance regarding EPA’s MOBILE
model was issued on November 12,
2002, which notified Federal, State, and
Local agencies that the updated
MOBILE6.2 model was now available
and was the recommended version of
the model to be used. We note that the
State used the MOBILE6.2 model to
revise the Ogden maintenance plan.
Our January 18, 2002, MOBILE6
policy allows areas to revise their motor
vehicle emission inventories and
transportation conformity MVEBs using
the MOBILE6 model without needing to
revise the entire SIP or completing
additional modeling if: (1) The SIP
continues to demonstrate attainment or
maintenance when the MOBILE5-based
motor vehicle emission inventories are
replaced with MOBILE6 base year and
VerDate Aug<18>2005
15:56 Sep 13, 2005
Jkt 205001
attainment/maintenance year
inventories and, (2) the State can
document that the growth and control
strategy assumptions for non-motor
vehicle emission sources continue to be
valid and minor updates do not change
the overall conclusion of the SIP. Our
January 18, 2002 MOBILE6 policy also
speaks specifically to CO maintenance
plans on page 10 of the policy. The first
paragraph on page 10 of the policy
states ‘‘* * *if a carbon monoxide (CO)
maintenance plan relied on either a
relative or absolute demonstration, the
first criterion could be satisfied by
documenting that the relative emission
reductions between the base year and
the maintenance year are the same or
greater using MOBILE6 as compared to
MOBILE5.’’
The State could have used the
streamlined approach described in our
January 18, 2002 MOBILE6 policy to
update the Ogden carbon monoxide
MVEBs. However, the Governor’s
November 29, 2004 SIP submittal
instead contained a completely revised
maintenance plan and maintenance
demonstration for the Ogden area. That
is, all emission source categories (point,
area, non-road, and on-road mobile)
were updated using the latest versions
of applicable models (including
MOBILE6.2,) transportation data sets,
emissions data, emission factors,
population figures and other
demographic information. We have
determined that this fully revised
maintenance plan SIP submittal exceeds
the requirements of our January 18,
2002 MOBILE6 policy and, therefore,
our January 18, 2002 MOBILE6 policy is
not relevant to our approval of the
revised maintenance plan and its
MVEBs.
As discussed above, the State
prepared a revised attainment year
inventory for 1992, and new emission
inventories for the years 2004, 2005,
2008, 2011, 2014, 2017, 2020 and 2021.
The results of these calculations are
presented in Table 3 ‘‘Emissions
Projections for Interim Years’’ on page 5
of the revised Ogden maintenance plan
(Utah SIP Section IX, Part C.8) and are
also summarized in our Table IV–1
above. In addition, we note that the
State modified the Weber County I/M
program to specify that vehicles less
than six years old are to have their
emissions tested every other year
instead of annually (see our discussion
and evaluation in section VI below.)
The State performed an analysis of
this relaxation of the Weber County I/M
program and determined that this
change could be implemented for Weber
County, beginning in 2005, without
jeopardizing maintenance of the CO
PO 00000
Frm 00036
Fmt 4700
Sfmt 4700
NAAQS. As noted below in section VI,
we reviewed the State’s methodology
and analysis and we have determined
they are acceptable. The effects of this
I/M rule relaxation were incorporated
into the State’s mobile sources modeling
with MOBILE6.2, as applicable to the
years 2005, 2008, 2011, 2014, 2017,
2020, and 2021, and these results are
reflected in the Table 3 of the
maintenance plan and in our Table IV–
1 above.
We have determined that the State has
demonstrated, using MOBILE6.2, that
mobile source emissions continuously
decline from 1992 to 2021 and that the
total CO emissions from all source
categories, projected for years 2004,
2005, 2008, 2011, 2014, 2017, 2020 and
2021, are all below the 1992 attainment
year level of CO emissions. Therefore,
we are approving the revised
maintenance plan as it demonstrates
maintenance of the CO NAAQS from
1992 through 2021, while allowing the
I/M relaxations from the revisions to the
Weber County I/M program.
(d) Monitoring Network and
Verification of Continued Attainment.
Continued attainment of the CO
NAAQS in the Ogden area depends, in
part, on the State’s efforts to track
indicators throughout the maintenance
period. This requirement is met in
section IX.C.8.e: ‘‘Monitoring Network/
Verification of Continued Attainment’’
of the revised Ogden CO maintenance
plan. In section IX.C.8.e, the State
commits to continue the operation of
the CO monitor in the Ogden area, in
accordance with the provisions of 40
CFR 58, and to annually review this
monitoring network and gain EPA
approval before making any changes.
Also, in section IX.C.8.e and IX.C.8.f,
the State commits to track mobile
sources’ CO emissions (which are the
largest component of the inventories)
through the ongoing regional
transportation planning process that is
done by the WFRC. Since regular
revisions to Ogden’s transportation
improvement programs and long range
transportation plans must go through a
transportation conformity finding, the
State will use this process to
periodically review the Vehicle Miles
Traveled (VMT) and mobile source
emissions projections used in the
revised maintenance plan. This regional
transportation conformity process is
conducted by WFRC in coordination
with Utah’s Division of Air Quality
(UDAQ), the UAQB, the Utah
Department of Transportation (UDOT)
and EPA.
Based on the above, we are approving
these commitments as satisfying the
relevant requirements. We note that our
E:\FR\FM\14SER1.SGM
14SER1
Federal Register / Vol. 70, No. 177 / Wednesday, September 14, 2005 / Rules and Regulations
final rulemaking approval renders the
State’s commitments federally
enforceable.
(e) Contingency Plan.
Section 175A(d) of the CAA requires
that a maintenance plan include
contingency provisions. To meet this
requirement, the State has identified
appropriate contingency measures along
with a schedule for the development
and implementation of such measures.
As stated in section IX.C.8.f of the
revised maintenance plan, the
contingency measures for the Ogden
area will be triggered by a violation of
the CO NAAQS. However, the State
approaches the development and
implementation of contingency
measures from a two-step process; first,
upon an exceedance of the CO NAAQS
and second, upon a violation of the CO
NAAQS.
The UDAQ will notify the Ogden City
government and EPA of an exceedance
of the CO NAAQS generally within 30,
but no more than 45 days. Upon
notification of a CO exceedance, the
UDAQ in coordination with the WFRC,
will begin evaluating and developing
potential contingency measures that are
intended to correct a violation of the CO
NAAQS. This process will be completed
within six months of the notification
that an exceedance of the CO NAAQS
has occurred. If a violation of the CO
NAAQS has occurred, a public hearing
process will begin at the local and State
levels. Should the UAQB conclude that
the implementation of local measures
will prevent further exceedances or
violations of the CO NAAQS, the UAQB
may approve or endorse local measures
without adopting State requirements. If,
however, the UDAQ decides locallyadopted contingency measures are
inadequate, the UDAQ will recommend
to the UAQB that they instead adopt
State-enforceable measures as deemed
necessary to address the current
violation(s) and prevent additional
exceedances or violations. Regardless of
whether the selected contingency
measures are local-or State-adopted, the
necessary contingency measures will be
implemented within one year of a CO
NAAQS violation. The State also
indicates in section IX.C.8.f that any
State-enforceable measure will become
part of the next revised maintenance
plan submitted for EPA approval.
The potential contingency measures
identified in section IX.C.8.f(3) of the
revised Ogden CO maintenance plan
include: (1) A return to annual
inspections for all vehicles; (2)
improvements to the current I/M
program in the Ogden area; (3)
mandatory employer-based travel
reduction programs as allowed by
VerDate Aug<18>2005
16:58 Sep 13, 2005
Jkt 205001
statute; (4) implementation of 2.7%
oxygenated gasoline in Weber County
from November 1 through the end of
February; (5) and other emission control
measures appropriate for the area.
Based on the above, we find that the
contingency measures provided in the
State’s revised Ogden CO maintenance
plan are sufficient and continue to meet
the requirements of section 175A(d) of
the CAA.
(f) Subsequent Maintenance Plan
Revisions.
Section IX.C.8.g of the State’s revised
maintenance plan states that:
‘‘No maintenance plan revision will be
needed after 2021, as that is the 20th year
following EPA approval of the original
maintenance plan. No further maintenance
plan is needed after successful maintenance
of the standard for 20 years. However, the
State will update the Plan if conditions
warrant.’’
This is essentially a correct
interpretation of the length of time that
an area is required to demonstrate
maintenance of the CO NAAQS as
provided in sections 175A(a) and
175A(b) of the CAA. Although this
language in section IX.C.8.g of the
revised Ogden CO maintenance plan
does not address the specific
requirements for the submittal of a
revised maintenance plan as stated in
section 175A(b) of the CAA, we have
concluded it is sufficient to meet the
intent of section 175A(b).
The requirement for a subsequent
maintenance plan submittal appears in
section 175A(b) of the CAA which states
‘‘8 years after redesignation of any area
as an attainment area under section
107(d), the State shall submit to the
Administrator an additional revision of
the applicable State implementation
plan for maintaining the national
primary ambient air quality standard for
10 years after the expiration of the 10year period referred to in subsection
(a).’’ As EPA redesignated the Ogden
City CO nonattainment area to
attainment on March 9, 2001, a
subsequent maintenance plan submittal
from the State, to address the
requirements of section 175A(b) of the
CAA, would normally be submitted to
us by March 9, 2009. However, as the
Governor’s November 29, 2004
submittal of the revised Ogden CO
maintenance plan provides a
sufficiently robust maintenance
demonstration through 2021, we find
that this revised maintenance plan
addresses the requirements of section
175A(b) of the CAA.
Regardless of the requirements of
section 175(A) of the CAA, though,
other sections of the CAA, presently in
place or adopted in the future, may
PO 00000
Frm 00037
Fmt 4700
Sfmt 4700
54271
require the State to revise the
maintenance plan and/or Utah SIP more
generally, to ensure that the area
continues to meet the CO NAAQS.
Section 110(a)(1) of the CAA is an
example of such a provision. Also, we
interpret the quoted statement above as
merely indicating that section 175A
does not require a further maintenance
plan revision after 2021; we do not
interpret it to mean that the
maintenance plan will automatically
terminate after 2021. EPA’s
longstanding interpretation is that SIP
provisions remain in place until EPA
approves a revision to such provisions.
The only exception is if the SIP contains
explicit language that some or all of its
provisions will terminate upon a
specific future date. The maintenance
plan does not contain such explicit
language. Based on our interpretation,
section IX.C.8.g of the State’s revised
maintenance plan is acceptable to us.
Based on our review and evaluation of
the components of the revised Ogden
CO maintenance plan, as discussed in
our items IV.(a) through IV.(f) above, we
have concluded that the State has met
the necessary requirements in order for
us to approve the revised Ogden CO
maintenance plan.
V. EPA’s Evaluation of the
Transportation Conformity
Requirements
One key provision of our conformity
regulation (40 CFR part 93) requires a
demonstration that emissions from the
long range transportation plan and
Transportation Improvement Program
are consistent with the emissions
budget(s) 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 62193–96) and in the sections of the
rule referenced above.
With respect to maintenance plans,
our conformity regulation requires that
MVEB(s) must be established for the last
year of the maintenance plan and may
be established for any other years
deemed appropriate (40 CFR 93.118).
For transportation plan analysis years
after the last year of the maintenance
plan (in this case 2021), a conformity
determination must show that emissions
are less than or equal to the
maintenance plan’s motor vehicle
emissions budget(s) for the last year of
the implementation plan. EPA’s
E:\FR\FM\14SER1.SGM
14SER1
54272
Federal Register / Vol. 70, No. 177 / Wednesday, September 14, 2005 / Rules and Regulations
conformity regulation (40 CFR 93.124)
also allows the implementation plan to
quantify explicitly the amount by which
motor vehicle emissions could be higher
while still demonstrating compliance
with the maintenance requirement. The
implementation plan can then allocate
some or all of this additional ‘‘safety
margin’’ to the emissions budget(s) for
transportation conformity purposes.
Section IX.C.8.d ‘‘Mobile Source
Carbon Monoxide Emissions Budgets for
Transportation Conformity’’ of the
revised Ogden CO maintenance plan
briefly describes the applicable
transportation conformity requirements,
provides MVEB calculations, identifies
‘‘safety margin,’’ and indicates that the
UAQB elected to apply some of the
‘‘safety margin’’ to the MVEB(s) for 2005
and 2021.
In section IX.C.8.d of the revised
maintenance plan, the State evaluated
two MVEBs: a budget for 2005, and a
budget applicable to the maintenance
year 2021. For the 2021 MVEB, the State
subtracted the total estimated 2021
emissions (from all sources) of 42.94
Tons Per Day (TPD) from the 1992
attainment year total emissions of
106.49 TPD. This produced a ‘‘safety
margin’’ of 63.55 TPD. The State then
reduced this ‘‘safety margin’’ by 20 TPD.
The identified ‘‘safety margin’’ of 43.55
TPD for 2021 was then added to the
estimated 2021 mobile sources
emissions, 29.47 TPD, to produce a 2021
MVEB of 73.02 TPD. For the 2005
MVEB, the State subtracted the total
estimated 2005 emissions (from all
sources) of 55.67 TPD from the 1992
attainment year total emissions of
106.49 TPD. This produced a ‘‘safety
margin’’ of 50.82 TPD. The State then
reduced this ‘‘safety margin’’ by 20 TPD.
The identified ‘‘safety margin’’ of 30.82
TPD for 2005 was then added to the
estimated 2005 mobile sources
emissions, 44.54 TPD, to produce a 2005
MVEB of 75.36 TPD.
As noted above, the Governor
submitted the original Ogden CO
maintenance plan to us on December 9,
1996 and we approved it on March 9,
2001 (see 66 FR 14078). This original
maintenance plan demonstrated
maintenance of the CO NAAQS through
2007. While our conformity rule (see 40
CFR 93) does not require a MVEB for
years other than the last year of the
maintenance period, states have the
option to establish MVEBs for other
years too. The State’s December 9, 1996,
maintenance plan established MVEB(s)
for 1992, 1993, 1994, 1995, 1996, 1997,
1998, 1999, 2000, 2001, 2002, 2003,
2004, 2005, 2006, 2007 and the years
2008 through 2017. As noted in our
March 9, 2001 action, the State
identified a 55 TPD MVEB for the years
2008 through 2017, and EPA approved
this 55 TPD MVBE for use in any
transportation conformity
determinations for the years 2008 and
beyond (see 66 FR 14078, pages 14083
and 14084).
The revised Ogden CO maintenance
plan, that was submitted to us on
November 29, 2004, states, ‘‘This plan
retracts the emissions budgets for 2005–
2017 that were included in the original
Ogden Carbon Monoxide Maintenance
Plan submitted to EPA in 1996.’’ EPA
interprets this language to mean that the
State is retracting the 1996 maintenance
plan budgets for years 2005, 2006, 2007,
and 2008 through 2017. The November
29, 2004 maintenance plan establishes
new MVEBs for 2005 and 2021 based on
MOBILE6.2. In part, the State chose
these budget years and retracted budgets
for other years based on input from
Region 8.
However, Region 8 recently
discovered that we misinterpreted the
CAA requirements regarding initial
maintenance plan MVEBs and
mistakenly advised the State that it
could entirely remove a MVEB for 2007
from the maintenance plan. Instead,
EPA’s interpretation is that a MVEB for
the last year of the first maintenance
period must be retained as a specific
MVEB year when a second maintenance
plan is submitted to meet the
requirements of section 175A(b) of the
CAA. We should have advised the State
to retain a MVEB for 2007.1
As described below, however, we
believe the lack of a 2007 MVEB in this
case is not significant and that approval
of the revised maintenance plan and
MVEBs is still warranted. In section IV
of this action, we describe how the
revised Ogden CO maintenance plan
meets our criteria for approval and that
the State has demonstrated maintenance
of the CO NAAQS for the entire
maintenance period through 2021.
Essentially, the State demonstrated that
total CO emissions in future years
through 2021 will be less than the 1992
attainment year level of CO emissions.
Table V–1 below, which is taken from
Table 3 of section IX.C.8.b of the State’s
revised maintenance plan, illustrates
this point. We have also included in this
table the available safety margin that the
State could have applied to the MVEB
in each projection year.

Based on the information from Table

retain the same exact budget. With a proper
demonstration, a state can revise the budget for the

estimates for 2005 and 2021 represent MVEBs established in the CO maintenance plan.
It is evident from the emissions trends
from 2005 forward, and from the
amount of remaining safety margin in
2005 and 2008, that the State could have
established 75.36 tons per day of CO as
the 2007 MVEB too. In other words, the
2005 MVEB is reasonably representative
of 2007.
A 2007 MVEB would have applied for
any conformity determination for
analysis years between 2007 and 2021.
The 2005 MVEB must be used for any
conformity determination for analysis
years between 2005 and 2021. See 40
CFR 93.118(b)(2)(iv). In other words, the
elimination of the 2007 MVEB has
limited, if any, practical effect. For a
conformity analysis of any
transportation plan or program, there
will still be a quantitative budget
analysis for any analysis years between
2005 and 2021, as required by 40 CFR
93.118(b), and conformity will have to
be shown to a MVEB of 75.36 TPD of
CO, the same MVEB the State could
have specified for 2007.
We also note that the 2005 MVEB is
reasonably representative of 2011. This
was the year for which EPA extracted
data from the State’s TSD in its March
9, 2001 action to meet the 10-year
maintenance requirement in section
175A(a) of the CAA. See 66 FR 14078.
Normally, the initial maintenance plan
would have established a MVEB for
2011, and the current maintenance plan
should then have included a MVEB for
2011. However, Table V–2 above shows
that a budget identical to the 2005
MVEB of 75.36 tons per day of CO could
have also been established in 2008 and
2011. Based on our discussion above
relative to MVEB for 2005 and 2007, and
the information from Table V–2, it is
evident that the 2005 MVEB could have
been established for 2011 as well. For

the same reasons that the lack of a 2007
MVEB has limited, if any, practical
effect, the lack of a 2011 MVEB also has
limited, if any, practical effect.
Pursuant to § 93.118(e)(4) of EPA’s
transportation conformity rule, as
amended, EPA must determine the
adequacy of submitted mobile source
emissions budgets. EPA reviewed the
revised Ogden CO maintenance plan’s
emission budget for 2021 for adequacy
using the criteria in 40 CFR 93.118(e)(4),
and determined that the budget was
adequate for conformity purposes.
EPA’s adequacy determination was
made in a letter to the Utah Division of
Air Quality May 2, 2005, and was
announced in the Federal Register on
May 26, 2005 (70 FR 30440). As a result
of this adequacy finding, the 2021
budget took effect for conformity
determinations in the Ogden area on
June 10, 2005. However, we note that
we are not bound by this determination
in acting on the revised Ogden CO
maintenance plan.
We have concluded that the State has
satisfactorily demonstrated continued
maintenance of the CO NAAQS while
using transportation conformity MVEBs
of 75.36 TPD for 2005 and 73.02 TPD for
2021. Therefore, we are approving the
transportation conformity MVEBs of
75.36 and 73.02 TPD of CO for the
Ogden attainment/maintenance area, for
2005 and 2021.
VI. EPA’s Evaluation of the Revised
Vehicle Inspection and Maintenance
Program
In developing the Ogden revised CO
maintenance plan, the State revised
section X, part E, of the Utah State
Implementation Plan, ‘‘Vehicle
Inspection and Maintenance Program,
Weber County,’’ to go from an annual to
PO 00000
Frm 00039
Fmt 4700
Sfmt 4700
an every-other-year testing program for
vehicles less than six years old.
The Weber County I/M program
revisions adopted by the UAQB on
November 3, 2004, State effective on
November 4, 2004, and submitted by the
Governor on November 29, 2004, reflect
the changes in State law, section 41–6–
163.4, Utah Code Annotated, for
implementing the I/M program in Weber
County. After EPA approval, this State
provision will become part of the
federally-enforceable SIP. The revised
maintenance plan reflects the changes
in the Weber County I/M program in
that mobile source CO emissions were
calculated for the Ogden area for the
years 2005, 2008, 2011, 2014, 2017,
2020, and 2021, assuming every-otheryear testing for vehicles less than six
years old. Even with this relaxation of
the I/M requirements, the emission
projections indicate that the Ogden area
will maintain the CO NAAQS from 2005
through 2021.
We note a discrepancy between the
Weber County I/M program and
appendix 1, ‘‘Weber-Morgan Health
Department Regulation for Motor
Vehicle Inspection Maintenance
Program’’ (hereafter ‘‘appendix 1’’).
Appendix 1, section 6.0, ‘‘General
Provisions,’’ indicates that the WeberMorgan Health Department can require
either an annual or biennial program.
The maintenance demonstration is
based on an annual program for vehicles
six years or older and a biennial
program for vehicles less than six years
old. Any decision by the Weber-Morgan
Health Department to expand the
biennial program to other vehicles will
only be federally effective upon EPA
approval as a SIP revision.
Also, section 13.2 of appendix 1
indicates that the adopted cut-points for
E:\FR\FM\14SER1.SGM
14SER1
54274
Federal Register / Vol. 70, No. 177 / Wednesday, September 14, 2005 / Rules and Regulations
motor vehicle emission inspections
contained in appendix C to appendix 1
shall remain in effect until changed by
the Board of Health. However, section
13.2 also states that the maximum
concentration of cut-points shall be
adopted by the Board of Health to meet
the NAAQS established by EPA. As
with the frequency of inspections
described above, the maintenance
demonstration is based on the cutpoints contained in appendix C to
appendix 1. Given this, any decision by
the Board of Health to change the cutpoints in Appendix C to Appendix 1
shall only be federally effective upon
EPA approval of such change as a SIP
revision.
This is consistent with the
interpretation of the Utah Division of
Air Quality expressed in an August 2,
2005 letter from Richard W. Sprott to
Gary House of the Weber-Morgan Board
of Health.
We have evaluated and determined
that the Weber County I/M program
revisions described above are acceptable
to us and we are approving them now
in conjunction with this action.
VII. Consideration of Section 110(l) of
the CAA
Section 110(l) of the CAA states that
a SIP revision cannot be approved if the
revision would interfere with any
applicable requirement concerning
attainment and reasonable further
progress towards attainment of a
NAAQS or any other applicable
requirement of the CAA. The revised
Ogden CO maintenance plan and Weber
County I/M program will not interfere
with attainment, reasonable further
progress, or any other applicable
requirement of the CAA.
VIII. Final Action
In this action, EPA is approving the
revised Ogden CO maintenance plan,
the revisions to Utah’s Rule R307–110–
12 (which incorporates the revised CO
maintenance plan into the Utah Rules,)
the revised transportation conformity
CO motor vehicle emission budget for
the years 2005 and 2021, the revised
Weber County vehicle inspection and
maintenance program, and the revisions
to Utah’s Rule R307–110–35 (which
incorporates the revised Weber County
vehicle inspection and maintenance
program into the Utah Rules,) all as
submitted by the Governor on
November 29, 2004.
EPA is 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, EPA is publishing
a separate document that will serve as
the proposal to approve the SIP revision
if adverse comments are filed. This rule
will be effective November 14, 2005
without further notice unless the
Agency receives adverse comments by
October 14, 2005. If the EPA receives
adverse comments, EPA will publish a
timely withdrawal in the Federal

address all public comments in a
subsequent final rule based on the
proposed rule. The 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,

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.
IX. 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
PO 00000
Frm 00040
Fmt 4700
Sfmt 4700
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 November 14,
2005. Filing a petition for

ACTION: Final rule.
AGENCY:
SUMMARY: This regulation establishes
two exemptions from the requirement of
a tolerance for residues of [alpha]-Dglucopyranoside, 2-ethylhexyl 6-O[alpha]-D glucopyranosyl- and [alpha]D-glucopyranoside, 2-ethylhexyl when
used as inert ingredients in or on
growing crops. Akzo Nobel Surface
Chemistry LLC submitted a petition to
EPA under the Federal Food, Drug, and
Cosmetic Act (FFDCA), as amended by
the Food Quality Protection Act of 1996
(FQPA), requesting an exemption from
the requirement of a tolerance. This
regulation eliminates the need to
establish a maximum permissible level
for residues of these two ethylhexyl
glucopyranoside chemicals.

Approval and Promulgation of Air Quality Implementation Plans;
State of Utah; Ogden City Revised Carbon Monoxide Maintenance Plan and
Approval of Related Revisions
AGENCY: Environmental Protection Agency (EPA).
ACTION: Direct final rule.
-----------------------------------------------------------------------
SUMMARY: EPA is taking direct final action approving State
Implementation Plan (SIP) revisions submitted by the State of Utah. On
November 29, 2004, the Governor of Utah submitted revisions to Utah's
Rule R307-110-12, ``Section IX, Control Measures for Area and Point
Sources, Part C, Carbon Monoxide,'' which incorporates a revised
maintenance plan for the Ogden carbon monoxide (CO) maintenance area
for the CO National Ambient Air Quality Standard (NAAQS). The revised
maintenance plan contains revised transportation conformity budgets for
the years 2005 and 2021. In addition, the Governor submitted revisions
to Utah's Rule R307-110-35, ``Section X, Vehicle Inspection and
Maintenance Program, Part E, Weber County,'' which incorporates a
revised vehicle inspection and maintenance program for Weber County. In
this action, EPA is approving the Ogden City CO revised maintenance
plan, the revised transportation conformity budgets, the revised
vehicle inspection and maintenance program for Weber County, and the
revisions to rules R307-110-12 and R307-110-35. This action is being
taken under section 110 of the Clean Air Act.
DATES: This rule is effective on November 14, 2005 without further
notice, unless EPA receives adverse comment by October 14, 2005. If
adverse comment is received, EPA will publish a timely withdrawal of
the direct final rule in the Federal Register informing the public that
the rule will not take effect.

II. What Is the Purpose of This Action?
In this action, we are approving a revised maintenance plan for the
Ogden CO attainment/maintenance area that is designed to keep the area
in attainment for CO through 2021, we're approving revised
transportation conformity motor vehicle emissions budgets (MVEBs), and
we're approving revisions to the vehicle inspection and maintenance
program for Weber County. We are also approving revisions to Utah's
Rule R307-110-12, ``Section IX, Control Measures for Area and Point
Sources, Part C, Carbon Monoxide,'' and Rule R307-110-35, ``Section X,
Vehicle Inspection and Maintenance Program, Part E, Weber County,''
which merely incorporate the State's SIP revisions to the Ogden CO
maintenance plan and the vehicle inspection and maintenance program for
Weber County, respectively.
We approved the original CO redesignation to attainment and
maintenance plan for the Ogden area on March 9, 2001 (see 66 FR 14078).
The original Ogden CO maintenance plan that we approved on March 9,
2001 (hereafter March 9, 2001 maintenance plan) utilized the then
applicable EPA mobile sources emission factor model, MOBILE5a. On
January 18, 2002, we issued policy guidance for States and local areas
to use to develop SIP revisions using the new, updated version of the
model, MOBILE6. The policy guidance was entitled ``Policy Guidance on
the Use of MOBILE6 for SIP Development and Transportation Conformity''
(hereafter, January 18, 2002 MOBILE6 policy). On November 12, 2002,
EPA's Office of Transportation and Air Quality (OTAQ) issued an updated
version of the MOBILE6 model, MOBILE6.2, and notified Federal, State,
and Local agency users of the model's availability. MOBILE6.2 contained
additional updates for air toxics and particulate matter. However, the
CO emission factors were essentially the same as in the MOBILE6 version
of the model.
For the revised maintenance plan, the State recalculated the CO
emissions for the 1992 attainment year, projected emission inventories
for 2004, 2005, 2008, 2011, 2014, 2017, 2020, and 2021, and calculated
all the mobile source emissions using MOBILE6.2. Based on projected
significant mobile source emission reductions for the interim years
between 2005 and 2021, the State's revised maintenance demonstration is
also able to accommodate the relaxation of certain provisions for newer
vehicles in the Weber County Vehicle Inspection and Maintenance (I/M)
Program while continuing to demonstrate maintenance of the CO NAAQS.
Thus, the State has asked us to approve a revision to ``Vehicle
Inspection and Maintenance Program, Weber County'' (hereafter referred
to as ``Weber County I/M
[[Page 54269]]
program'' or ``I/M program'')that allows vehicles less than six years
old to be inspected every other year instead of annually. The State
calculated a CO MVEB for 2005 and applied a selected amount of the
available safety margin to the 2005 transportation conformity MVEB. The
State calculated a CO MVEB for 2021 and beyond and also applied a
selected amount of the available safety margin to the 2021 and beyond
transportation conformity MVEB. We have determined that all the
revisions noted above are Federally-approvable, as described further
below.
III. 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 Utah Air Quality Board (UAQB) held a public hearing for the
revised Ogden CO maintenance plan, the revised Weber County vehicle
inspection and maintenance program, and the revisions to Rule R307-110-
12 and Rule R307-110-35 on September 22, 2004. The revised plan
elements and rules were adopted by the UAQB on November 3, 2004. The
revised CO maintenance plan and Rule R307-110-12 became State effective
on January 4, 2005 and the revised vehicle inspection and maintenance
program and Rule R307-110-35 became State effective on November 4,
2004. The Governor submitted these SIP revisions to us on November 29,
2004. Additional administrative materials were submitted to us by the
State on March 3, 2005.
We have evaluated the Governor's submittal for these SIP revisions
and have determined that the State met the requirements for reasonable
notice and public hearing under section 110(a)(2) of the CAA. As
required by section 110(k)(1)(B) 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. Our completeness determination was sent on
March 22, 2005, through a letter from Robert E. Roberts, Regional
Administrator, to Governor Jon Huntsman Jr.
IV. EPA's Evaluation of the Revised Maintenance Plan
EPA has reviewed the State's revised maintenance plan for the Ogden
attainment/maintenance 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 has air quality data that show continuous attainment
of the CO NAAQS.
As described in 40 CFR 50.8, the national primary ambient air
quality standard for carbon monoxide is 9 parts per million (10
milligrams per cubic meter) for an 8-hour average concentration not to
be exceeded more than once per year. 40 CFR 50.8 continues by stating
that the levels of CO in the ambient air shall be measured by a
reference method based on 40 CFR part 50, appendix C and designated in
accordance with 40 CFR part 53 or an equivalent method designated in
accordance with 40 CFR part 53. The March 9, 2001 maintenance plan
relied on ambient air quality data from 1992 through 1999. In our
consideration of the revised Ogden maintenance plan, submitted by the
Governor on November 29, 2004, we reviewed ambient air quality data
from 1992 through 2004. The Ogden area shows continuous attainment of
the CO NAAQS from 1992 to present. All of the above-referenced air
quality data are archived in our Air Quality System (AQS).
(b) Using the MOBILE6.2 emission factor model, the State revised
the attainment year inventory (1992) and provided projected emissions
inventories for the years 2004, 2005, 2008, 2011, 2014, 2017, 2020, and
2021.
The revised maintenance plan that the Governor submitted on
November 29, 2004, includes comprehensive inventories of CO emissions
for the Ogden area. These inventories include emissions from stationary
point sources, area sources, non-road mobile sources, and on-road
mobile sources. More detailed descriptions of the revised 1992
attainment year inventory, and the projected emissions inventories for
2004, 2005, 2008, 2011, 2014, 2017, 2020, and 2021, are documented in
the maintenance plan in section IX.C.8.b entitled ``Emission
Inventories and Maintenance Demonstration,'' and in the State's
Technical Support Document (TSD). The State's submittal contains
emission inventory information that was prepared in accordance with EPA
guidance. Summary emission figures from the 1992 attainment year and
the projected years are provided in Table IV-1 below.

* There were no major CO point sources in the Ogden maintenance area; the State included point source emissions
in the Area source category.
[[Page 54270]]
The revised mobile source emissions show that the largest change
from the original March 9, 2001 maintenance plan is primarily due to
the use of MOBILE6.2 instead of MOBILE5a. The MOBILE6.2 modeling
information is contained in the State's TSD (see ``Mobile Source 1992
Base Year Inventory Using MOBILE6.2,'' pages 3.b.v-1 through 3.b.v-5;
and ``Mobile Source Projection Year Inventories Using MOBILE6.2,''
pages 4.e-1 through 4.e-3) and on a compact disk produced by the State
(see ``Supplemental Mobile Source Data (CD-ROM),'' section 2.d.). A
copy of the State's compact disk is available upon request to EPA. The
compact disk contains much of the modeling data, MOBILE6.2 input-output
files, fleet makeup, MOBILE6.2 input parameters, and other information,
and is included with the docket for this action. Other revisions to the
mobile sources category resulted from revised vehicle miles traveled
(VMT) estimates provided to the State by the Wasatch Front Regional
Council (WFRC) which is the metropolitan planning organization (MPO)
for the Ogden area. In summary, the revised maintenance plan and State
TSD contain detailed emission inventory information that was prepared
in accordance with EPA guidance and is acceptable to EPA.
(c) The State revised the March 9, 2001 Ogden maintenance plan.
The March 9, 2001 CO maintenance plan utilized the then applicable
EPA mobile sources emission factor model, MOBILE5a. On January 18,
2002, we issued policy guidance for States and local areas to use to
develop SIP revisions using the updated version of the model, MOBILE6.
The policy guidance was entitled ``Policy Guidance on the Use of
MOBILE6 for SIP Development and Transportation Conformity'' (hereafter,
January 18, 2002 MOBILE6 policy). Additional policy guidance regarding
EPA's MOBILE model was issued on November 12, 2002, which notified
Federal, State, and Local agencies that the updated MOBILE6.2 model was
now available and was the recommended version of the model to be used.
We note that the State used the MOBILE6.2 model to revise the Ogden
maintenance plan.
Our January 18, 2002, MOBILE6 policy allows areas to revise their
motor vehicle emission inventories and transportation conformity MVEBs
using the MOBILE6 model without needing to revise the entire SIP or
completing additional modeling if: (1) The SIP continues to demonstrate
attainment or maintenance when the MOBILE5-based motor vehicle emission
inventories are replaced with MOBILE6 base year and attainment/
maintenance year inventories and, (2) the State can document that the
growth and control strategy assumptions for non-motor vehicle emission
sources continue to be valid and minor updates do not change the
overall conclusion of the SIP. Our January 18, 2002 MOBILE6 policy also
speaks specifically to CO maintenance plans on page 10 of the policy.
The first paragraph on page 10 of the policy states ``* * *if a carbon
monoxide (CO) maintenance plan relied on either a relative or absolute
demonstration, the first criterion could be satisfied by documenting
that the relative emission reductions between the base year and the
maintenance year are the same or greater using MOBILE6 as compared to
MOBILE5.''
The State could have used the streamlined approach described in our
January 18, 2002 MOBILE6 policy to update the Ogden carbon monoxide
MVEBs. However, the Governor's November 29, 2004 SIP submittal instead
contained a completely revised maintenance plan and maintenance
demonstration for the Ogden area. That is, all emission source
categories (point, area, non-road, and on-road mobile) were updated
using the latest versions of applicable models (including MOBILE6.2,)
transportation data sets, emissions data, emission factors, population
figures and other demographic information. We have determined that this
fully revised maintenance plan SIP submittal exceeds the requirements
of our January 18, 2002 MOBILE6 policy and, therefore, our January 18,
2002 MOBILE6 policy is not relevant to our approval of the revised
maintenance plan and its MVEBs.
As discussed above, the State prepared a revised attainment year
inventory for 1992, and new emission inventories for the years 2004,
2005, 2008, 2011, 2014, 2017, 2020 and 2021. The results of these
calculations are presented in Table 3 ``Emissions Projections for
Interim Years'' on page 5 of the revised Ogden maintenance plan (Utah
SIP Section IX, Part C.8) and are also summarized in our Table IV-1
above. In addition, we note that the State modified the Weber County I/
M program to specify that vehicles less than six years old are to have
their emissions tested every other year instead of annually (see our
discussion and evaluation in section VI below.)
The State performed an analysis of this relaxation of the Weber
County I/M program and determined that this change could be implemented
for Weber County, beginning in 2005, without jeopardizing maintenance
of the CO NAAQS. As noted below in section VI, we reviewed the State's
methodology and analysis and we have determined they are acceptable.
The effects of this I/M rule relaxation were incorporated into the
State's mobile sources modeling with MOBILE6.2, as applicable to the
years 2005, 2008, 2011, 2014, 2017, 2020, and 2021, and these results
are reflected in the Table 3 of the maintenance plan and in our Table
IV-1 above.
We have determined that the State has demonstrated, using
MOBILE6.2, that mobile source emissions continuously decline from 1992
to 2021 and that the total CO emissions from all source categories,
projected for years 2004, 2005, 2008, 2011, 2014, 2017, 2020 and 2021,
are all below the 1992 attainment year level of CO emissions.
Therefore, we are approving the revised maintenance plan as it
demonstrates maintenance of the CO NAAQS from 1992 through 2021, while
allowing the I/M relaxations from the revisions to the Weber County I/M
program.
(d) Monitoring Network and Verification of Continued Attainment.
Continued attainment of the CO NAAQS in the Ogden area depends, in
part, on the State's efforts to track indicators throughout the
maintenance period. This requirement is met in section IX.C.8.e:
``Monitoring Network/Verification of Continued Attainment'' of the
revised Ogden CO maintenance plan. In section IX.C.8.e, the State
commits to continue the operation of the CO monitor in the Ogden area,
in accordance with the provisions of 40 CFR 58, and to annually review
this monitoring network and gain EPA approval before making any
changes.
Also, in section IX.C.8.e and IX.C.8.f, the State commits to track
mobile sources' CO emissions (which are the largest component of the
inventories) through the ongoing regional transportation planning
process that is done by the WFRC. Since regular revisions to Ogden's
transportation improvement programs and long range transportation plans
must go through a transportation conformity finding, the State will use
this process to periodically review the Vehicle Miles Traveled (VMT)
and mobile source emissions projections used in the revised maintenance
plan. This regional transportation conformity process is conducted by
WFRC in coordination with Utah's Division of Air Quality (UDAQ), the
UAQB, the Utah Department of Transportation (UDOT) and EPA.
Based on the above, we are approving these commitments as
satisfying the relevant requirements. We note that our
[[Page 54271]]
final rulemaking approval renders the State's commitments federally
enforceable.
(e) Contingency Plan.
Section 175A(d) of the CAA requires that a maintenance plan include
contingency provisions. To meet this requirement, the State has
identified appropriate contingency measures along with a schedule for
the development and implementation of such measures.
As stated in section IX.C.8.f of the revised maintenance plan, the
contingency measures for the Ogden area will be triggered by a
violation of the CO NAAQS. However, the State approaches the
development and implementation of contingency measures from a two-step
process; first, upon an exceedance of the CO NAAQS and second, upon a
violation of the CO NAAQS.
The UDAQ will notify the Ogden City government and EPA of an
exceedance of the CO NAAQS generally within 30, but no more than 45
days. Upon notification of a CO exceedance, the UDAQ in coordination
with the WFRC, will begin evaluating and developing potential
contingency measures that are intended to correct a violation of the CO
NAAQS. This process will be completed within six months of the
notification that an exceedance of the CO NAAQS has occurred. If a
violation of the CO NAAQS has occurred, a public hearing process will
begin at the local and State levels. Should the UAQB conclude that the
implementation of local measures will prevent further exceedances or
violations of the CO NAAQS, the UAQB may approve or endorse local
measures without adopting State requirements. If, however, the UDAQ
decides locally-adopted contingency measures are inadequate, the UDAQ
will recommend to the UAQB that they instead adopt State-enforceable
measures as deemed necessary to address the current violation(s) and
prevent additional exceedances or violations. Regardless of whether the
selected contingency measures are local-or State-adopted, the necessary
contingency measures will be implemented within one year of a CO NAAQS
violation. The State also indicates in section IX.C.8.f that any State-
enforceable measure will become part of the next revised maintenance
plan submitted for EPA approval.
The potential contingency measures identified in section
IX.C.8.f(3) of the revised Ogden CO maintenance plan include: (1) A
return to annual inspections for all vehicles; (2) improvements to the
current I/M program in the Ogden area; (3) mandatory employer-based
travel reduction programs as allowed by statute; (4) implementation of
2.7% oxygenated gasoline in Weber County from November 1 through the
end of February; (5) and other emission control measures appropriate
for the area.
Based on the above, we find that the contingency measures provided
in the State's revised Ogden CO maintenance plan are sufficient and
continue to meet the requirements of section 175A(d) of the CAA.
(f) Subsequent Maintenance Plan Revisions.
Section IX.C.8.g of the State's revised maintenance plan states
that:
``No maintenance plan revision will be needed after 2021, as
that is the 20th year following EPA approval of the original
maintenance plan. No further maintenance plan is needed after
successful maintenance of the standard for 20 years. However, the
State will update the Plan if conditions warrant.''
This is essentially a correct interpretation of the length of time
that an area is required to demonstrate maintenance of the CO NAAQS as
provided in sections 175A(a) and 175A(b) of the CAA. Although this
language in section IX.C.8.g of the revised Ogden CO maintenance plan
does not address the specific requirements for the submittal of a
revised maintenance plan as stated in section 175A(b) of the CAA, we
have concluded it is sufficient to meet the intent of section 175A(b).
The requirement for a subsequent maintenance plan submittal appears
in section 175A(b) of the CAA which states ``8 years after
redesignation of any area as an attainment area under section 107(d),
the State shall submit to the Administrator an additional revision of
the applicable State implementation plan for maintaining the national
primary ambient air quality standard for 10 years after the expiration
of the 10-year period referred to in subsection (a).'' As EPA
redesignated the Ogden City CO nonattainment area to attainment on
March 9, 2001, a subsequent maintenance plan submittal from the State,
to address the requirements of section 175A(b) of the CAA, would
normally be submitted to us by March 9, 2009. However, as the
Governor's November 29, 2004 submittal of the revised Ogden CO
maintenance plan provides a sufficiently robust maintenance
demonstration through 2021, we find that this revised maintenance plan
addresses the requirements of section 175A(b) of the CAA.
Regardless of the requirements of section 175(A) of the CAA,
though, other sections of the CAA, presently in place or adopted in the
future, may require the State to revise the maintenance plan and/or
Utah SIP more generally, to ensure that the area continues to meet the
CO NAAQS. Section 110(a)(1) of the CAA is an example of such a
provision. Also, we interpret the quoted statement above as merely
indicating that section 175A does not require a further maintenance
plan revision after 2021; we do not interpret it to mean that the
maintenance plan will automatically terminate after 2021. EPA's
longstanding interpretation is that SIP provisions remain in place
until EPA approves a revision to such provisions. The only exception is
if the SIP contains explicit language that some or all of its
provisions will terminate upon a specific future date. The maintenance
plan does not contain such explicit language. Based on our
interpretation, section IX.C.8.g of the State's revised maintenance
plan is acceptable to us.
Based on our review and evaluation of the components of the revised
Ogden CO maintenance plan, as discussed in our items IV.(a) through
IV.(f) above, we have concluded that the State has met the necessary
requirements in order for us to approve the revised Ogden CO
maintenance plan.
V. EPA's Evaluation of the Transportation Conformity Requirements
One key provision of our conformity regulation (40 CFR part 93)
requires a demonstration that emissions from the long range
transportation plan and Transportation Improvement Program are
consistent with the emissions budget(s) 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 62193-96) and in the sections of the rule
referenced above.
With respect to maintenance plans, our conformity regulation
requires that MVEB(s) must be established for the last year of the
maintenance plan and may be established for any other years deemed
appropriate (40 CFR 93.118). For transportation plan analysis years
after the last year of the maintenance plan (in this case 2021), a
conformity determination must show that emissions are less than or
equal to the maintenance plan's motor vehicle emissions budget(s) for
the last year of the implementation plan. EPA's
[[Page 54272]]
conformity regulation (40 CFR 93.124) also allows the implementation
plan to quantify explicitly the amount by which motor vehicle emissions
could be higher while still demonstrating compliance with the
maintenance requirement. The implementation plan can then allocate some
or all of this additional ``safety margin'' to the emissions budget(s)
for transportation conformity purposes.
Section IX.C.8.d ``Mobile Source Carbon Monoxide Emissions Budgets
for Transportation Conformity'' of the revised Ogden CO maintenance
plan briefly describes the applicable transportation conformity
requirements, provides MVEB calculations, identifies ``safety margin,''
and indicates that the UAQB elected to apply some of the ``safety
margin'' to the MVEB(s) for 2005 and 2021.
In section IX.C.8.d of the revised maintenance plan, the State
evaluated two MVEBs: a budget for 2005, and a budget applicable to the
maintenance year 2021. For the 2021 MVEB, the State subtracted the
total estimated 2021 emissions (from all sources) of 42.94 Tons Per Day
(TPD) from the 1992 attainment year total emissions of 106.49 TPD. This
produced a ``safety margin'' of 63.55 TPD. The State then reduced this
``safety margin'' by 20 TPD. The identified ``safety margin'' of 43.55
TPD for 2021 was then added to the estimated 2021 mobile sources
emissions, 29.47 TPD, to produce a 2021 MVEB of 73.02 TPD. For the 2005
MVEB, the State subtracted the total estimated 2005 emissions (from all
sources) of 55.67 TPD from the 1992 attainment year total emissions of
106.49 TPD. This produced a ``safety margin'' of 50.82 TPD. The State
then reduced this ``safety margin'' by 20 TPD. The identified ``safety
margin'' of 30.82 TPD for 2005 was then added to the estimated 2005
mobile sources emissions, 44.54 TPD, to produce a 2005 MVEB of 75.36
TPD.
As noted above, the Governor submitted the original Ogden CO
maintenance plan to us on December 9, 1996 and we approved it on March
9, 2001 (see 66 FR 14078). This original maintenance plan demonstrated
maintenance of the CO NAAQS through 2007. While our conformity rule
(see 40 CFR 93) does not require a MVEB for years other than the last
year of the maintenance period, states have the option to establish
MVEBs for other years too. The State's December 9, 1996, maintenance
plan established MVEB(s) for 1992, 1993, 1994, 1995, 1996, 1997, 1998,
1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007 and the years 2008
through 2017. As noted in our March 9, 2001 action, the State
identified a 55 TPD MVEB for the years 2008 through 2017, and EPA
approved this 55 TPD MVBE for use in any transportation conformity
determinations for the years 2008 and beyond (see 66 FR 14078, pages
14083 and 14084).
The revised Ogden CO maintenance plan, that was submitted to us on
November 29, 2004, states, ``This plan retracts the emissions budgets
for 2005-2017 that were included in the original Ogden Carbon Monoxide
Maintenance Plan submitted to EPA in 1996.'' EPA interprets this
language to mean that the State is retracting the 1996 maintenance plan
budgets for years 2005, 2006, 2007, and 2008 through 2017. The November
29, 2004 maintenance plan establishes new MVEBs for 2005 and 2021 based
on MOBILE6.2. In part, the State chose these budget years and retracted
budgets for other years based on input from Region 8.
However, Region 8 recently discovered that we misinterpreted the
CAA requirements regarding initial maintenance plan MVEBs and
mistakenly advised the State that it could entirely remove a MVEB for
2007 from the maintenance plan. Instead, EPA's interpretation is that a
MVEB for the last year of the first maintenance period must be retained
as a specific MVEB year when a second maintenance plan is submitted to
meet the requirements of section 175A(b) of the CAA. We should have
advised the State to retain a MVEB for 2007.\1\
---------------------------------------------------------------------------
\1\ This doesn't mean the State would have had to retain the
same exact budget. With a proper demonstration, a state can revise
the budget for the last year of the first 10-year maintenance
period.
---------------------------------------------------------------------------
As described below, however, we believe the lack of a 2007 MVEB in
this case is not significant and that approval of the revised
maintenance plan and MVEBs is still warranted. In section IV of this
action, we describe how the revised Ogden CO maintenance plan meets our
criteria for approval and that the State has demonstrated maintenance
of the CO NAAQS for the entire maintenance period through 2021.
Essentially, the State demonstrated that total CO emissions in future
years through 2021 will be less than the 1992 attainment year level of
CO emissions. Table V-1 below, which is taken from Table 3 of section
IX.C.8.b of the State's revised maintenance plan, illustrates this
point. We have also included in this table the available safety margin
that the State could have applied to the MVEB in each projection year.

* The State indicated there were no major point sources of CO and that point source emissions were included with
the Area Sources category.
Based on the information from Table V-1 above, Table V-2 below
illustrates the State-specified MVEBs for 2005 and 2021. It also shows
that, based on available safety margin, the State could have specified
the same 2005 budget of 75.36 TPD for any of the other projection
years. We note the emissions estimates for 2008, 2011, 2014, 2017,
[[Page 54273]]
and 2020 are provided in Table V-2 for illustrative purposes only;
emissions estimates for these years do not represent MVEBs.

** Emissions estimates for 2005 and 2021 represent MVEBs established in the CO maintenance plan.
It is evident from the emissions trends from 2005 forward, and from
the amount of remaining safety margin in 2005 and 2008, that the State
could have established 75.36 tons per day of CO as the 2007 MVEB too.
In other words, the 2005 MVEB is reasonably representative of 2007.
A 2007 MVEB would have applied for any conformity determination for
analysis years between 2007 and 2021. The 2005 MVEB must be used for
any conformity determination for analysis years between 2005 and 2021.
See 40 CFR 93.118(b)(2)(iv). In other words, the elimination of the
2007 MVEB has limited, if any, practical effect. For a conformity
analysis of any transportation plan or program, there will still be a
quantitative budget analysis for any analysis years between 2005 and
2021, as required by 40 CFR 93.118(b), and conformity will have to be
shown to a MVEB of 75.36 TPD of CO, the same MVEB the State could have
specified for 2007.
We also note that the 2005 MVEB is reasonably representative of
2011. This was the year for which EPA extracted data from the State's
TSD in its March 9, 2001 action to meet the 10-year maintenance
requirement in section 175A(a) of the CAA. See 66 FR 14078. Normally,
the initial maintenance plan would have established a MVEB for 2011,
and the current maintenance plan should then have included a MVEB for
2011. However, Table V-2 above shows that a budget identical to the
2005 MVEB of 75.36 tons per day of CO could have also been established
in 2008 and 2011. Based on our discussion above relative to MVEB for
2005 and 2007, and the information from Table V-2, it is evident that
the 2005 MVEB could have been established for 2011 as well. For the
same reasons that the lack of a 2007 MVEB has limited, if any,
practical effect, the lack of a 2011 MVEB also has limited, if any,
practical effect.
Pursuant to Sec. 93.118(e)(4) of EPA's transportation conformity
rule, as amended, EPA must determine the adequacy of submitted mobile
source emissions budgets. EPA reviewed the revised Ogden CO maintenance
plan's emission budget for 2021 for adequacy using the criteria in 40
CFR 93.118(e)(4), and determined that the budget was adequate for
conformity purposes. EPA's adequacy determination was made in a letter
to the Utah Division of Air Quality May 2, 2005, and was announced in
the Federal Register on May 26, 2005 (70 FR 30440). As a result of this
adequacy finding, the 2021 budget took effect for conformity
determinations in the Ogden area on June 10, 2005. However, we note
that we are not bound by this determination in acting on the revised
Ogden CO maintenance plan.
We have concluded that the State has satisfactorily demonstrated
continued maintenance of the CO NAAQS while using transportation
conformity MVEBs of 75.36 TPD for 2005 and 73.02 TPD for 2021.
Therefore, we are approving the transportation conformity MVEBs of
75.36 and 73.02 TPD of CO for the Ogden attainment/maintenance area,
for 2005 and 2021.
VI. EPA's Evaluation of the Revised Vehicle Inspection and Maintenance
Program
In developing the Ogden revised CO maintenance plan, the State
revised section X, part E, of the Utah State Implementation Plan,
``Vehicle Inspection and Maintenance Program, Weber County,'' to go
from an annual to an every-other-year testing program for vehicles less
than six years old.
The Weber County I/M program revisions adopted by the UAQB on
November 3, 2004, State effective on November 4, 2004, and submitted by
the Governor on November 29, 2004, reflect the changes in State law,
section 41-6-163.4, Utah Code Annotated, for implementing the I/M
program in Weber County. After EPA approval, this State provision will
become part of the federally-enforceable SIP. The revised maintenance
plan reflects the changes in the Weber County I/M program in that
mobile source CO emissions were calculated for the Ogden area for the
years 2005, 2008, 2011, 2014, 2017, 2020, and 2021, assuming every-
other-year testing for vehicles less than six years old. Even with this
relaxation of the I/M requirements, the emission projections indicate
that the Ogden area will maintain the CO NAAQS from 2005 through 2021.
We note a discrepancy between the Weber County I/M program and
appendix 1, ``Weber-Morgan Health Department Regulation for Motor
Vehicle Inspection Maintenance Program'' (hereafter ``appendix 1'').
Appendix 1, section 6.0, ``General Provisions,'' indicates that the
Weber-Morgan Health Department can require either an annual or biennial
program. The maintenance demonstration is based on an annual program
for vehicles six years or older and a biennial program for vehicles
less than six years old. Any decision by the Weber-Morgan Health
Department to expand the biennial program to other vehicles will only
be federally effective upon EPA approval as a SIP revision.
Also, section 13.2 of appendix 1 indicates that the adopted cut-
points for
[[Page 54274]]
motor vehicle emission inspections contained in appendix C to appendix
1 shall remain in effect until changed by the Board of Health. However,
section 13.2 also states that the maximum concentration of cut-points
shall be adopted by the Board of Health to meet the NAAQS established
by EPA. As with the frequency of inspections described above, the
maintenance demonstration is based on the cut-points contained in
appendix C to appendix 1. Given this, any decision by the Board of
Health to change the cut-points in Appendix C to Appendix 1 shall only
be federally effective upon EPA approval of such change as a SIP
revision.
This is consistent with the interpretation of the Utah Division of
Air Quality expressed in an August 2, 2005 letter from Richard W.
Sprott to Gary House of the Weber-Morgan Board of Health.
We have evaluated and determined that the Weber County I/M program
revisions described above are acceptable to us and we are approving
them now in conjunction with this action.
VII. Consideration of Section 110(l) of the CAA
Section 110(l) of the CAA states that a SIP revision cannot be
approved if the revision would interfere with any applicable
requirement concerning attainment and reasonable further progress
towards attainment of a NAAQS or any other applicable requirement of
the CAA. The revised Ogden CO maintenance plan and Weber County I/M
program will not interfere with attainment, reasonable further
progress, or any other applicable requirement of the CAA.
VIII. Final Action
In this action, EPA is approving the revised Ogden CO maintenance
plan, the revisions to Utah's Rule R307-110-12 (which incorporates the
revised CO maintenance plan into the Utah Rules,) the revised
transportation conformity CO motor vehicle emission budget for the
years 2005 and 2021, the revised Weber County vehicle inspection and
maintenance program, and the revisions to Utah's Rule R307-110-35
(which incorporates the revised Weber County vehicle inspection and
maintenance program into the Utah Rules,) all as submitted by the
Governor on November 29, 2004.
EPA is 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, EPA is publishing a separate document
that will serve as the proposal to approve the SIP revision if adverse
comments are filed. This rule will be effective November 14, 2005
without further notice unless the Agency receives adverse comments by
October 14, 2005. If the EPA receives adverse comments, EPA will
publish a timely withdrawal in the Federal Register informing the
public that the rule will not take effect. EPA will address all public
comments in a subsequent final rule based on the proposed rule. The 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
this 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.
IX. 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 November 14, 2005. Filing a
petition for reconsideration by the Administrator of
[[Page 54275]]
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).)
