Below are two tables with roughly accurate estimates of cost and be nefits 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 ex pressed 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 di fferences, but I find the construct of mo ving between costs and benefits dependent on your baseline or control case confusing at best and quite possibly misleading. Wh en we did our 2007 rule the trucking industry cost to drive a mile was something on th e order of $1 per mile. Our fuel quality change increased that by about a penny and changes in ma intenance 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 m y 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 m y baseline becomes a private benefit in m y control case and then goes back to being a cost in m y bas e 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 compone nts (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 ass um e 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 tim e since the average reader will certainly assume they can add up EP A cost estimates from mu ltiple 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 - By ron
