Hi Chandana,

I had expected to hear back yesterday with at least a tentative idea of
next steps on the rulemaking package.   Our senior teams at both NHTSA
and EPA assume we are working through the issues raised in interagency
review in a timely manner.  I am hesitant to reassure them that is true
not knowing even generally the outcome from your discussions yesterday.

Please give Jim or myself a call as soon as possible.

Thanks,

Byron

Subject:	HD NPRM Economy Wide Modelling



Hi Chandana,

Attached below is a note from our economics team describing the advice
of the Science Advisory Board and specific language improvements we have
made in this section relative to the LD NPRM.

I will follow up with the team on the question that we discussed
yesterday, but let me repeat it here to make sure I understand.

The interagency group generally accepts that these regulations should
lead to a reduction in transportation prices inherent in our VMT rebound
estimate.  The stumbling block seems to be how well does the general
equilibrium economy wide model relate a price change in the
transportation sector to an overall GDP change.  I will ask the team
what kind of information we have that would answer questions about the
validity of the model to make that kind of estimate.

I am assuming that we will talk about this at 11:00.

Thanks,

Byron

Subject:	Economy-Wide Analysis justification



	As requested in the conference call yesterday, attached is the SAB
review of the EPA Guidelines for Preparing Economic Analysis.  As you
will note, the SAB was supportive of EPA's guidance to use general
equilibrium modeling to capture the impact of regulations that will have
significant impacts beyond those directly subject to regulation.  (see
highlighted sections in the attachment)

	In addition, we have also attached a copy of the 2010 peer review
report of the IGEM and ADAGE models, which also recommends incorporating
the use of CGE models in EPA's analysis of climate related policies . 
According to this report, "On balance, these are two excellent models
that provide useful information to EPA as it goes about its work of
evaluating climate policies...These models are essential tools for the
analysis of environmental policy in general and climate policy in
particular."   (see highlighted sections in the attachment)

	Also, we think it is important to point out that in response to some of
the issues raised in context of the Light-Duty rulemaking, we have
modified the preamble and RIA language to be as specific as possible on
what the analysis represents, and what it does not represent.  For
example, we have included caveat language that points out that the GDP
and consumption information does not represent a welfare analysis:

"Note that GDP changes should not be confused with a measure of welfare
since it focuses only on changes in what is produced by the economy, not
what is consumed." (Preamble Chapter 8.L(1), footnote in 2nd paragraph)

	

	In addition, we are explicit that the results of the economy-wide
analysis are dependent upon our assumptions regarding fuel savings.  

"It is important to note, however, that these potential impacts do not
represent additional benefits or costs from the regulation.  Instead,
they represent the effects on the U.S. economy as its direct benefits
and costs are transmitted through changes in prices and quantities sold
in the affected markets, including those for vehicles and their
components, fuel, and the various resources used to supply them.  The
predicted impacts of the regulation on economic activity depend on what
we assume with regard to fuel savings.  In particular, it depends on the
extent to which market failures affecting demand for vehicle fuel
economy are present, and when they are not, the extent to which they are
offset by costs not captured in EPA and NHTSA's analysis.  Such costs
include changes in economic welfare due to the purchase of more fuel
economy than businesses would otherwise elect to purchase absent
regulation." (Preamble Chapter 8.L, 3rd paragraph)

	However, if there is specific language that you are still uncomfortable
with, we welcome suggested edits and would like to work address those
issues.

Hi Chandana,

Attached is the current version of the HD NPRM preamble.  It should
reflect all of the changes we have discussed over the last few weeks.

I have left the document in track changes format so that you can quickly
find the changes from the previous version.  If you print the document
you will notice that the tables will lose all of their formatting (no
lines or boxes) and some of the footnotes will be indented twice.  Those
issues were introduced by me today editing using MS Word 2003.  I am
told that our team can easily correct that on Monday to make it right
again in Word 2007.

If you have any questions about the document please feel free to call me
any time at (734) 353-9623.

Thanks,

Byron

2) Excerpt from the FRM Preamble (page: 25510 of the May 7, 2010 FR)

EPA has undertaken an analysis of the economy-wide impacts of the GHG
tailpipe standards as an exploratory exercise that EPA believes could
provide additional insights into the potential impacts of the
program.436 These results were not a factor regarding

the appropriateness of the GHG tailpipe standards. It is important to
note that the results of this modeling exercise are dependent on the
assumptions associated with how producers will make fuel economy
improvements and how consumers will respond to increases in higher
vehicle costs and improved vehicle fuel economy as a result of the
program.

Subject:	HD NPM - Economy wide modelling



Hi Chandana,

Following is a discussion of how price changes are propagated through
the economy wide modelling.  Please let me know if we can provide
anything else.

Thanks,

Byron

The impact of fuel price changes on the rest of the economy is
determined endogenously within IGEM, and is governed by the structure of
production and consumption in the model.  All of the parameters in the
model are econometrically estimated using a data set that includes a
sequence of input-output tables spanning 50 years.  The use of fully
flexible translog functional forms with econmetrically estimated
parameters allows historical behavior to govern response to price shocks
in the model. (see Christensen, L; Jorgenson, D; and L. Lau.  (1973) 
"Transcendental Logarithmic Production Frontiers"  The Review of
Economics and Statistics.  Vol. 55, No. 1 (Feb., 1973))

The methodology used by the IGEM model for estimating price responses
throughout the economy has been successfully peer reviewed recently
(See: Peer Review of Computable General Equilibrium Models for Climate
Change

Analysis, April 2010, sent last week).  Several relevant excerpts are
included below:

What are the overall major strengths and weaknesses of the model for
EPA’s intended purpose?

The main strength of both models [IGEM and ADAGE] is their internal
consistency and ability to capture complex interactions among different
sectors of the economy in response to climate policy. Both also have
considerable detail about energy production and industry sectors that
are particularly sensitive to higher energy prices from climate policy.

...

IGEM’s strengths are its econometric calibration to historical data,
ability to capture detailed sectoral impacts, and its sophisticated
representation of endogenous incremental technological change.

Are the underlying data used to benchmark the model (e.g. input-output
table or Social Accounting Matrix) appropriate?

As Donald Rumsfeld might have said, you develop a model based on the
data you have, not what you might like to have. However, even given this
caveat,economic data used in these models appears to be adequate and
certainly the best that is readily available. ADAGE uses IMPLAN social
accounting data, widely recognized as some of the best subregional
economic data. ADAGE also used GTAP data for international information,
similarly the best that is available. The IGEM model is also closely
tied to data. Given that the IGEM model has been developed over several
decades, and has used the best national data that is available, IGEM
cannot be faulted in terms of economic data used to estimate the model.

Subject:	Conceptual Framework Passback



Hi Chandana,

Here is a new version of the conceptual framework language.  If the
interagency would like further edits, I suggest we setup a conference
call today to work through them and close out this discussion.

Following up on our call yesterday, the Monopsony discussion has been
redone in the RIA and preamble to follow the LD rule language.   We have
updated the fuel savings language to parallel the approach from LD (fuel
savings as benefits in 2014-18 model year discussions, shown both ways
in calendar year discussions).  Economy wide modelling is done exactly
as LD (the section is deleted in its entirety and the sentences from LD
brought to the same location in this package).   Our updated AB&T
language is copied below in a separate document.

I believe the only open item from yesterday's call is the table from the
LD 2012-2016 rule executive summary that you wanted carried over in
concept for this proposal.  If you can send me the table number, we will
be glad to follow up.

Thanks,

Byron

Subject:	Fw: Energy Security Impact comparison



Hi Chandana,

I asked the team to pull together a comparison of the LD 2012-2016 rule
and HD NPRM monopsony related discussions to make it easier to walk back
and forth between those two documents.   I think you will see they are
essentially the same.

Please feel free to call me anytime.  

Thanks,

Byron

Subject:	Energy Security Impact comparison



Byron,

Attached is a document which contains the sections discussing Energy
Security Impacts in the HD preamble and RIA along with the LD preamble,
RIA, and TSD.  Comment bubbles show that all of the text in the HD
preamble and RIA are either identical to or essentially the same as LD. 
The areas which are essentially the same are due to differences in the
analysis (MOVES) or year (2020 vs. 2015).

Subject:	Updated Alternatives Tables with Net Benefits



Hi Chandana,

Here is a new excerpt that includes two new tables for calendar years
2030 and 2050 showing the net benefits for the alternatives.  If you can
confirm that the formatting looks OK to you, we will get these added to
the preamble and RIA.

Thanks,

Byron

Subject:	Redline Strikeout HD NPRM



Hi Chandana,

Attached is a redline strikeout of the HD preamble tracking changes from
our first OMB submittal.  This should reflect all of the edits we have
discussed over the last three months.  The only open issue that I am
aware of is the question of annualized accounting.

I will send the RIA chapters and executive summary as separate mailings.

Thanks,

Byron

Subject:	Annualized cost table and related text



Hi Chandana,

We are inserting the following table and text into the preamble section
on Executive Orders in the subsection on Unfunded Mandates with the
other relevant economic data summarized there.  We are also adding it as
the first table in the executive summary of the RIA replacing the table
you saw previously.

Jim and I will be calling you in a few minutes to talk about the other
edit requests.

Thanks,

Byron
