II. What is the purpose of this action?
In this action, EPA is proposing to
approve a revision to Colorado’s
Regulation Number 11 (hererafter
‘‘Regulation No. 11’’), ‘‘Motor Vehicle
Emissions Inspection Program.’’ This
revision would remove the light duty
vehicle emission testing limits (or
‘‘cutpoints’’) that went into effect on
January 1, 2006 (hereafter referred to as
the ‘‘2006 cutpoints’’) for 1996 and
newer model year vehicles.1 The
emission testing limits that went into
effect on January 1, 2003 under
Regulation No. 11 (hereafter referred to
as the ‘‘2003 cutpoints’’) would
continue to be federally enforceable if
1 We note that the State never implemented the
2006 cutpoints. However, EPA approved them as
part of Regulation No. 11, and they have been
federally enforceable.
VerDate Mar<15>2010
14:14 Jan 11, 2012
Jkt 226001
we approve this revision. Under
Regulation No. 11, a vehicle whose
emissions exceed the applicable
emissions cutpoints during an IM240
emissions test will fail the test and must
be repaired and re-inspected.2
The 2006 cutpoints are 0.60 grams per
mile for hydrocarbons (HC), 10.0 grams
per mile for carbon monoxide (CO), and
1.5 grams per mile for oxides of nitrogen
(NOX). The 2003 cutpoints are 1.2 grams
per mile for HC, 20 grams per mile for
CO, and 3.0 grams per mile for NOX. We
have determined, and provide our
rationale for our determination below,
that it is reasonable for the State to
remove the 2006 cutpoints from
Regulation No. 11. If we approve this
revision to Regulation No. 11, it will
become part of the federally enforceable
SIP for Colorado under the Clean Air
Act (CAA).
III. What is the State’s process to
submit SIP revisions to EPA?
Section 110(k) of the CAA addresses
our actions on submissions of revisions
to a SIP. The CAA requires states to
observe certain procedural requirements
in developing SIP revisions for
submittal to us. Section 110(a)(2) of the
CAA requires that each SIP revision be
adopted after reasonable notice and
public hearing. This must occur prior to
the revision being submitted by a state
to us.
The Colorado Air Quality Control
Commission (AQCC) held a public
hearing on the revision to Regulation
No. 11 on November 17, 2005. The
AQCC adopted the revision to
Regulation No. 11 directly after the
hearing. This SIP revision became State
effective on March 2, 2006, and the
Governor submitted it to us on August
8, 2006.
We have evaluated the Governor’s
submittal for Regulation No. 11 and
2 A motor vehicle inspection and maintenance
(I/M) program is a control measure that is
sometimes used in SIPs to reduce emissions of
certain air pollutants. Today’s cars are dependent
on properly functioning emission control systems to
keep pollution levels low. I/M programs can
identify problem cars and ensure that cars are
properly maintained. Through Regulation No. 11,
the state of Colorado operates an enhanced I/M
program, relying mainly on an IM240 inspection
test. The IM240 test is a chassis dynamometer test
used for emission testing of light duty vehicles. It
is a short, 240 second test representing a 1.96 mile
route. Under Regulation No. 11, a vehicle whose
emissions exceed the applicable emissions
cutpoints during an IM240 emissions test will fail
the test and must be repaired and re-inspected.
Colorado operates an enhanced IM240 test program
in the following counties: Adams, Arapahoe,
Boulder, Broomfield, Denver, Douglas and Jefferson
(Denver metropolitan area). In addition, the State
operates an enhanced program in Larimer and Weld
Counties, but as a State-only (not Federally
enforceable) requirement.

have determined that the State met the
requirements for reasonable notice and
public hearing under section 110(a)(2)
of the CAA.
IV. EPA’s Evaluation of the State’s
August 8, 2006 Submittal
We have reviewed the revision to
Regulation. No. 11 that the State
submitted on August 8, 2006 and find
that our approval is warranted. We note
that we are only acting on the State’s
revision to Regulation No. 11, Part F
‘‘Maximum Allowable Emissions Limits
for Motor Vehicle Exhaust, Evaporative
and Visible Emissions for Light-Duty
and Heavy Duty Vehicles,’’ section
III.A.2. On August 17, 2007, EPA
approved other revisions to Regulation
No. 11 that the State had adopted on
November 17, 2005 (see 72 FR 46148).
We describe the basis for our proposed
approval below:
Basis for EPA’s proposed approval:
the State did not need the 2006 cupoints
to attain the 1997 8-hour (80 ppb) ozone
NAAQS.
The metro-Denver/North Front Range
(‘‘NFR’’) area was designated as
nonattainment for the 1997 8-hour (80
ppb) ozone NAAQS on November 20,
2007 (see 72 FR 53952, September 21,
2007). As a result of this nonattainment
designation, Colorado was required to
submit a dispersion modeled attainment
demonstration that demonstrated
attainment of the ozone NAAQS by the
end of the ozone season in 2010. The
State submitted a dispersion modeled
attainment demonstration SIP revision
on June 18, 2009 that demonstrated
attainment by the end of the 2010 ozone
season. EPA approved the State’s June
18, 2009 SIP revision on August 5, 2011
(see 76 FR 47443). In its attainment
demonstration for the 80 ppb 8-hour
ozone NAAQS, the State modeled the
2003 cutpoints, not the 2006 cutpoints.
We also note that monitored ambient air
quality data from 2008 through 2010
reflect that the metro-Denver/NFR area
attained the 80 ppb 8-hour ozone
NAAQS in 2010 without the
implementation of the 2006 cutpoints.3
In addition, based on preliminary
8-hour ozone data from 2011, the area
continues to demonstrate attainment of
the 80 ppb 8-hour ozone NAAQS.
Because the 2006 cutpoints have not
been necessary for the area to attain the
80 ppb 8-hour ozone NAAQS, we are
proposing to approve the State’s
removal of the 2006 cutpoints from
Regulation No. 11.
3 The State never implemented the 2006
cutpoints.

1894
Federal Register / Vol. 77, No. 8 / Thursday, January 12, 2012 / Proposed Rules
V. Consideration of Section 110(1) of
the Clean Air Act
Section 110(1) 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. EPA has
concluded that the above-described
revision to Regulation No. 11 will not
interfere with attainment, reasonable
further progress, or any other applicable
requirement of the CAA. This revision
to Regulation No. 11 will not adversely
affect the approved maintenance plans
for Metro-Denver and Longmont for
carbon monoxide (see 72 FR 46148,
August 17, 2007), Metro-Denver for
PM10 (see 72 FR 62571, November 6,
2007), or Greeley for carbon monoxide
(see 70 FR 48650), or the approved
attainment plan for Metro-Denver/NFR
for the 1997 8-hour (80 ppb) ozone
standard (see 76 FR 47443, August 5,
2011). For each of these areas and
pollutants, the State demonstrated
maintenance or attainment of the
relevant NAAQS assuming either the
complete absence of an I/M program or
the implementation of the 2003
cutpoints.
VI. Proposed Action
EPA is proposing approval of the
revision to Regulation No. 11 that the
State of Colorado submitted on August
8, 2006. The revision removes from
Regulation No. 11, Part F, section
III.A.2, the light duty vehicle emission
testing limits that went into effect on
January 1, 2006.

VII. Statutory and Executive Order
Reviews
Under the Clean Air Act, the
Administrator is required to approve a
SIP submission that complies with the
provisions of the Act and applicable
Federal regulations. 42 U.S.C. 7410(k);
40 CFR 52.02(a). Thus, in reviewing SIP
submissions, EPA’s role is to approve
state choices, provided that they meet
the criteria of the Clean Air Act.
Accordingly, this action merely
approves state law as meeting Federal
requirements and does not impose
additional requirements beyond those
imposed by state law. For that reason,
this action:
• Is not a ‘‘significant regulatory
action’’ subject to review by the Office
of Management and Budget under
Executive Order 12866 (58 FR 51735,
October 4, 1993);
• Does not impose an information
collection burden under the provisions
VerDate Mar<15>2010
14:14 Jan 11, 2012
Jkt 226001
of the Paperwork Reduction Act (44
U.S.C. 3501 et seq.);
• Is certified as not having a
significant economic impact on a
substantial number of small entities
under the Regulatory Flexibility Act
(5 U.S.C. 601 et seq.);
• 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);
• Does not have Federalism
implications as specified in Executive
Order 13132 (64 FR 43255, August 10,
1999);
• Is not an economically significant
regulatory action based on health or
safety risks subject to Executive Order
13045 (62 FR 19885, April 23, 1997);
• Is not a significant regulatory action
subject to Executive Order 13211 (66 FR
28355, May 22, 2001);
• Is not subject to requirements of
Section 12(d) of the National
Technology Transfer and Advancement
Act of 1995 (15 U.S.C. 272 note) because
application of those requirements would
be inconsistent with the Clean Air Act;
and
• Does not provide EPA with the
discretionary authority to address, as
appropriate, disproportionate human
health or environmental effects, using
practicable and legally permissible
methods, under Executive Order 12898
(59 FR 7629, February 16, 1994).
In addition, this rule does not have
tribal implications as specified by
Executive Order 13175 (65 FR 67249,
November 9, 2000), because the SIP is
not approved to apply in Indian country
located in the state, and EPA notes that
it will not impose substantial direct
costs on tribal governments or preempt
tribal law.

substitute language for your requested changes.
d. Describe any assumptions and provide any technical information
and/or data that you used.
e. If you estimate potential costs or burdens, explain how you
arrived at your estimate in sufficient detail to allow for it to be
reproduced.
f. Provide specific examples to illustrate your concerns, and
suggest alternatives.
g. Explain your views as clearly as possible, avoiding the use of
profanity or personal threats.
h. Make sure to submit your comments by the comment period deadline
identified.
II. What is the purpose of this action?
In this action, EPA is proposing to approve a revision to
Colorado's Regulation Number 11 (hererafter ``Regulation No. 11''),
``Motor Vehicle Emissions Inspection Program.'' This revision would
remove the light duty vehicle emission testing limits (or
``cutpoints'') that went into effect on January 1, 2006 (hereafter
referred to as the ``2006 cutpoints'') for 1996 and newer model year
vehicles.\1\ The emission testing limits that went into effect on
January 1, 2003 under Regulation No. 11 (hereafter referred to as the
``2003 cutpoints'') would continue to be federally enforceable if we
approve this revision. Under Regulation No. 11, a vehicle whose
emissions exceed the applicable emissions cutpoints during an IM240
emissions test will fail the test and must be repaired and re-
inspected.\2\
---------------------------------------------------------------------------
\1\ We note that the State never implemented the 2006 cutpoints.
However, EPA approved them as part of Regulation No. 11, and they
have been federally enforceable.
\2\ A motor vehicle inspection and maintenance (I/M) program is
a control measure that is sometimes used in SIPs to reduce emissions
of certain air pollutants. Today's cars are dependent on properly
functioning emission control systems to keep pollution levels low.
I/M programs can identify problem cars and ensure that cars are
properly maintained. Through Regulation No. 11, the state of
Colorado operates an enhanced I/M program, relying mainly on an
IM240 inspection test. The IM240 test is a chassis dynamometer test
used for emission testing of light duty vehicles. It is a short, 240
second test representing a 1.96 mile route. Under Regulation No. 11,
a vehicle whose emissions exceed the applicable emissions cutpoints
during an IM240 emissions test will fail the test and must be
repaired and re-inspected. Colorado operates an enhanced IM240 test
program in the following counties: Adams, Arapahoe, Boulder,
Broomfield, Denver, Douglas and Jefferson (Denver metropolitan
area). In addition, the State operates an enhanced program in
Larimer and Weld Counties, but as a State-only (not Federally
enforceable) requirement.
---------------------------------------------------------------------------
The 2006 cutpoints are 0.60 grams per mile for hydrocarbons (HC),
10.0 grams per mile for carbon monoxide (CO), and 1.5 grams per mile
for oxides of nitrogen (NOX). The 2003 cutpoints are 1.2
grams per mile for HC, 20 grams per mile for CO, and 3.0 grams per mile
for NOX. We have determined, and provide our rationale for
our determination below, that it is reasonable for the State to remove
the 2006 cutpoints from Regulation No. 11. If we approve this revision
to Regulation No. 11, it will become part of the federally enforceable
SIP for Colorado under the Clean Air Act (CAA).
III. What is the State's process to submit SIP revisions to EPA?
Section 110(k) of the CAA addresses our actions on submissions of
revisions to a SIP. The CAA requires states to observe certain
procedural requirements in developing SIP revisions for submittal to
us. Section 110(a)(2) of the CAA requires that each SIP revision be
adopted after reasonable notice and public hearing. This must occur
prior to the revision being submitted by a state to us.
The Colorado Air Quality Control Commission (AQCC) held a public
hearing on the revision to Regulation No. 11 on November 17, 2005. The
AQCC adopted the revision to Regulation No. 11 directly after the
hearing. This SIP revision became State effective on March 2, 2006, and
the Governor submitted it to us on August 8, 2006.
We have evaluated the Governor's submittal for Regulation No. 11
and have determined that the State met the requirements for reasonable
notice and public hearing under section 110(a)(2) of the CAA.
IV. EPA's Evaluation of the State's August 8, 2006 Submittal
We have reviewed the revision to Regulation. No. 11 that the State
submitted on August 8, 2006 and find that our approval is warranted. We
note that we are only acting on the State's revision to Regulation No.
11, Part F ``Maximum Allowable Emissions Limits for Motor Vehicle
Exhaust, Evaporative and Visible Emissions for Light-Duty and Heavy
Duty Vehicles,'' section III.A.2. On August 17, 2007, EPA approved
other revisions to Regulation No. 11 that the State had adopted on
November 17, 2005 (see 72 FR 46148). We describe the basis for our
proposed approval below:
Basis for EPA's proposed approval: the State did not need the 2006
cupoints to attain the 1997 8-hour (80 ppb) ozone NAAQS.
The metro-Denver/North Front Range (``NFR'') area was designated as
nonattainment for the 1997 8-hour (80 ppb) ozone NAAQS on November 20,
2007 (see 72 FR 53952, September 21, 2007). As a result of this
nonattainment designation, Colorado was required to submit a dispersion
modeled attainment demonstration that demonstrated attainment of the
ozone NAAQS by the end of the ozone season in 2010. The State submitted
a dispersion modeled attainment demonstration SIP revision on June 18,
2009 that demonstrated attainment by the end of the 2010 ozone season.
EPA approved the State's June 18, 2009 SIP revision on August 5, 2011
(see 76 FR 47443). In its attainment demonstration for the 80 ppb 8-
hour ozone NAAQS, the State modeled the 2003 cutpoints, not the 2006
cutpoints. We also note that monitored ambient air quality data from
2008 through 2010 reflect that the metro-Denver/NFR area attained the
80 ppb 8-hour ozone NAAQS in 2010 without the implementation of the
2006 cutpoints.\3\ In addition, based on preliminary 8-hour ozone data
from 2011, the area continues to demonstrate attainment of the 80 ppb
8-hour ozone NAAQS.
---------------------------------------------------------------------------
\3\ The State never implemented the 2006 cutpoints.
---------------------------------------------------------------------------
Because the 2006 cutpoints have not been necessary for the area to
attain the 80 ppb 8-hour ozone NAAQS, we are proposing to approve the
State's removal of the 2006 cutpoints from Regulation No. 11.
[[Page 1894]]
V. Consideration of Section 110(1) of the Clean Air Act
Section 110(1) 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. EPA has concluded that the above-described revision to
Regulation No. 11 will not interfere with attainment, reasonable
further progress, or any other applicable requirement of the CAA. This
revision to Regulation No. 11 will not adversely affect the approved
maintenance plans for Metro-Denver and Longmont for carbon monoxide
(see 72 FR 46148, August 17, 2007), Metro-Denver for PM10
(see 72 FR 62571, November 6, 2007), or Greeley for carbon monoxide
(see 70 FR 48650), or the approved attainment plan for Metro-Denver/NFR
for the 1997 8-hour (80 ppb) ozone standard (see 76 FR 47443, August 5,
2011). For each of these areas and pollutants, the State demonstrated
maintenance or attainment of the relevant NAAQS assuming either the
complete absence of an I/M program or the implementation of the 2003
cutpoints.
VI. Proposed Action
EPA is proposing approval of the revision to Regulation No. 11 that
the State of Colorado submitted on August 8, 2006. The revision removes
from Regulation No. 11, Part F, section III.A.2, the light duty vehicle
emission testing limits that went into effect on January 1, 2006.
VII. Statutory and Executive Order Reviews
Under the Clean Air Act, the Administrator is required to approve a
SIP submission that complies with the provisions of the Act and
applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a).
Thus, in reviewing SIP submissions, EPA's role is to approve state
choices, provided that they meet the criteria of the Clean Air Act.
Accordingly, this action merely approves state law as meeting Federal
requirements and does not impose additional requirements beyond those
imposed by state law. For that reason, this action:
Is not a ``significant regulatory action'' subject to
review by the Office of Management and Budget under Executive Order
12866 (58 FR 51735, October 4, 1993);
Does not impose an information collection burden under the
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
Is certified as not having a significant economic impact
on a substantial number of small entities under the Regulatory
Flexibility Act (5 U.S.C. 601 et seq.);
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);
Does not have Federalism implications as specified in
Executive Order 13132 (64 FR 43255, August 10, 1999);
Is not an economically significant regulatory action based
on health or safety risks subject to Executive Order 13045 (62 FR
19885, April 23, 1997);
Is not a significant regulatory action subject to
Executive Order 13211 (66 FR 28355, May 22, 2001);
Is not subject to requirements of Section 12(d) of the
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272
note) because application of those requirements would be inconsistent
with the Clean Air Act; and
Does not provide EPA with the discretionary authority to
address, as appropriate, disproportionate human health or environmental
effects, using practicable and legally permissible methods, under
Executive Order 12898 (59 FR 7629, February 16, 1994).
In addition, this rule does not have tribal implications as
specified by Executive Order 13175 (65 FR 67249, November 9, 2000),
because the SIP is not approved to apply in Indian country located in
the state, and EPA notes that it will not impose substantial direct
costs on tribal governments or preempt tribal law.
