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,

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

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

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
