RE: marginal cost estimates used in PM NAAQS RIAs

Thanks Ron, very helpful -

I appreciate your team taking the time to help us understand the

analysis, given the very short timeline we have for review --

Subject: marginal cost estimates used in PM NAAQS RIAs

Heidi, after yesterday's conversation, I thought it would be useful to

provide some additional background info for you since you were not

around for the PM NAAQS RIA analysis.   Here is a copy of the cost

chapter for that analysis.   If you look at pages 6-26 thru 6-28, you

will see we followed the same principle of picking a point off the cost

curve in that analysis as we have in the current ozone analysis.   While

this only addresses one of the points you raised yesterday, I thought it

would be useful for you to see how we used these curves in the past.

Obviously, we have tried to go further in this analysis with the

characterization of the costs.   Let me know if you have any questions

about what we did previously.

Talk to you later this afternoon about the baseline issue!
