Subject

updated chapter 7b: Uncertainties of Post 2020 Attainment Analysis

Heidi, here is the updated chapter on SC & SJ reflecting our
conversation this am about including a fuller characterization of the
uncertainties.   Let me know if you have questions.

We will be faxing change pages reflecting differences between what you
have in hand and the draft we have now reflecting renumbered chapters
etc.   We will start that in about a 1/2 hour or less, Janet is
finishing off the changes now.   I do not expect much more than a dozen
or so pages but stay tuned.

Ron
