Hi Chandana,

Yes, I will be the main contact for EPA. You should feel free to call me anytime. If you miss me 

in my office, don't hesitate to call my cellphone.

Thanks,

Hi Chandana,

I checked with Margo's office this afternoon, and they are confident that she would like to be part 

of our staff briefing on the Heavy-Duty package. Could you please coordinate with Gladys 

Bryant-Akers (564-1682) to get the briefing onto Margo's calendar as well?

Thursday, August 26 remains the best date for the EPA staff in Ann Arbor. Given Margo's 

interest in participating, we will travel for the meeting. Hence, there is no need to coordinate a 

video call.

Thanks,

Byron

Subject:Treatment of Fuel Savings

Hi Chandana,

I thought a more concrete example would be helpful in our discussion of accounting for fuel 

savings as a negative cost or a benefit. Below are two tables with roughly accurate estimates of 

cost and benefits from the 2007 heavy-duty rule and our proposed HD fuel efficiency and GHG 

rules. These are only a partial accounting for illustrative purposes and the numbers are based 

on very round estimates ($3/gal, 6mpg, 138 billion VMT, $6.5 B VSL,...)

I expressed the cost numbers in cents per mile because I think that is conceptually easier to 

follow. I converted that to billions of dollars using VMT for the benefits column and the bottom 

totals.

I know that to you these seem like arbitrary accounting differences, but I find the construct of 

moving between costs and benefits dependent on your baseline or control case confusing at best 

and quite possibly misleading.

When we did our 2007 rule the trucking industry cost to drive a mile was something on the order 

of $1 per mile. Our fuel quality change increased that by about a penny and changes in 

maintenance practices (oil change interval) decreased that by about 0.2 cents. Hence, EPA 

would say as a result of our rule that costs have gone up by about 0.8 cents per mile. OMB 

would say costs went up by 1 cent per mile and there was a 0.2 cent benefit realized.

Now when it is time for this rule, what is my proper baseline? I assume I should start with a cost 

of $1.008 per mile (the actual cost per mile for the industry). Does OMB think I should start with a 

cost of $1.01 per mile? I assume not.

This is the part I find so confusing. A cost that is in my baseline becomes a private benefit in my 

control case and then goes back to being a cost in my base case for the next rule.

I think you can see why this would be a concern for EPA over time. Often when we estimate the 

cost for changes to vehicles we add new components (e.g. an integrated starter generator) 

increasing cost and remove existing components (e.g. the alternator) reducing costs. If we call 

the $500 increase for the integrated starter generator a cost and the $100 savings for removing 

the alternator a benefit, we end the rule with a $500 cost. Obviously, the general public is going 

to assume EPA has estimated that costs for vehicles will go up $500 if we report that as our cost 

and bury the $100 alternator savings within the benefits. This gets even more confusing over 

time since the average reader will certainly assume they can add up EPA cost estimates from 

multiple rules. Of course, that approach does not work if cost savings are moved into the benefits 

column.

I am hoping that we can talk about this more at our call today.

Thanks - Byron
