the reason for the change, how the
change was incorporated into the
EMFAC model, and the resulting
emissions impact. All presentations
from the public workshops are available
on the CARB Web site at: https://
www.arb.ca.gov/msei/
workshops.htm#work200612. These
presentations summarize the major
changes to the EMFAC model and
contain tables showing the impacts of
the changes both statewide and by
county for HC, CO, NOX, PM10, and
PM2.5.
F. Will a Transportation Conformity
Grace Period Be Set by This Approval?
Yes. The transportation conformity
rule (40 CFR part 93.111) requires that
conformity analyses be based on the
latest motor vehicle emissions model
approved by EPA for SIP purposes for
a state or area. Section 176(c)(1) of the
CAA states that ‘‘* * * [t]he
determination of conformity shall be
based on the most recent estimates of
emissions, and such estimates shall be
determined from the most recent
population, employment, travel, and
congestion estimates. * * *’’ When EPA
approves a new emissions model such
as EMFAC2007, a grace period is
established before the model is required
for conformity analyses. However, areas
have the option of using the new model
prior to the end of the grace period. The
conformity rule provides for a grace
period for new emissions models of
between 3 to 24 months. In consultation
with FHWA and FTA, EPA considers
many factors in establishing the length
of the grace period, including the degree
of change in emissions models and the
effects of the new model on the
transportation planning process (40 CFR
93.111).
Upon consideration of all of these
factors, EPA is establishing a 3-month
grace period before EMFAC2007 is
required for the following conformity
analyses:
• All new HC, NOX, PM10, PM2.5 and
CO regional emissions analyses (e.g.,
supporting transportation plan and TIP
conformity determinations); and
• All new CO hot-spot analyses
supporting project-level conformity
determinations.
The grace period begins today and
ends on April 18, 2008. As discussed
earlier in the notice, the last version of
EMFAC (EMFAC2002) is no longer used
in California for new regional emissions
analyses for transportation plan and TIP
conformity determinations. Therefore it
is appropriate to set a short grace period
since all areas in California will need to
use EMFAC2007 to begin any new
regional conformity analyses. A longer

grace period would provide no practical
benefit for transportation plan and TIP
conformity determinations, since older
EMFAC models cannot be used in new
regional analyses due to the latest
planning assumptions requirements in
the conformity rule (40 CFR 93.110).
When the grace period ends on April
18, 2008, EMFAC2007 will become the
only approved motor vehicle emissions
model for all new regional and CO hotspot transportation conformity analyses
across California. In general, this means
that all new HC, NOX, PM10, PM2.5, and
CO regional conformity analyses and CO
hot-spot analyses started after the end of
the 3-month grace period must be based
on EMFAC2007, even if the SIP is based
on an earlier version of the EMFAC
model.
G. Can Areas Use Any Other Models
During the Grace Period?
Yes, in limited cases. CO hot-spot
analyses for project-level conformity
determinations can be based on
EMFAC2002 if the analysis was begun
before the end of the grace period,
started before August 1, 2007 and if the
final environmental document for the
project is issued no more than three
years after the issuance of the draft
environmental document (see 40 CFR
93.111(c)). The interagency consultation
process should be used if it is unclear
whether an EMFAC2002 based analysis
is covered by the circumstances
described above.
H. Future Updates to EMFAC
On January 31, 2006, CARB submitted
a letter to EPA and to the California
Division of the FHWA indicating the
State’s intention to update future
revisions to EMFAC. These EMFAC
updates would reflect, among other new
information, updated vehicle fleet data
every three years. In California,
Metropolitan Planning Organizations
and Air Districts have not been able to
update vehicle fleet data embedded into
EMFAC. The EPA/USDOT January 18,
2001, guidance on latest planning
assumptions and EPA’s July 2004 final
rule, indicate that new vehicle
registration data must be used when it
is available prior to the start of new
conformity analyses and that states
should update the data at least every
five years. The State reaffirmed their
commitment to keeping the latest
planning assumptions included in
EMFAC updated on a three year cycle
in the April 18, 2007 EMFAC submittal
letter. The next update to the planning
assumptions in EMFAC is expected in
2010, which would most likely also
include updates to the emissions factors
of the model as well.

III. Summary of EPA Actions
EPA is approving EMFAC2007 as
submitted by CARB on April 18, 2007
with the following limitations and
conditions:
(1) The approval is limited to
California.
(2) The approval is Statewide and
applies to estimation of emissions of
hydrocarbon, carbon monoxide,
nitrogen oxides, particulate matter
(PM10 and PM2.5), lead, and sulfur
oxides. However, EMFAC2007 will only
be used in transportation conformity
analyses for pollutants and precursors
that affect regional on-road mobile
emissions and are applicable in a given
nonattainment or maintenance area.
EPA is also approving EMFAC2007 to
estimate hot-spot emissions for carbon
monoxide conformity analyses.
(3) A 3-month statewide
transportation conformity grace period
will be established beginning January
18, 2008 and ending April 18, 2008 for
the transportation conformity uses
described in (2) above.
