Subject

meeting today @ 1 on baseline controls









Heidi, I chatted with my technical staff this am.  I wanted to give you
a heads up on our position prior to the meeting this afternoon as a
point of departure.  Here are the basics:

- We have already analyzed the costs for implementing the current
standard in a separate regualtory package on ozone implementation a few
years ago so we do not plan to present costs for meeting the current
standard in the O3 RIA.  Let me know if you need a copy of the analysis.

- That previous analysis was for a different analytical year (2010) and
based on different inventories, modeling etc.  Thus, it was necessary
for us to prepare an updated scenario for meeting the current standard
to provide a baseline for the alternative standard analysis.

- In the Chapter 5 Appendix for the O3 RIA, we are including technical
information for the engineering costs for the controls used in the
baseline, or references to cost information for these controls.  For
example, we will present the cost data on the 3 mobile source controls
(e.g. plug-in hybrids) which we were discussing yesterday in this
appendix.

I hope this helps frame the discussion.  Talk to you @ 1:00

The call-in # is 919.541.4427
