follow-up from our discussion on extrapolated costs

Rob,

     Thanks for joining us last Thursday the 8th to talk about our
extrapolated costs methodology choices.  I'm glad we were able to reach
agreement on the methods to apply to those places that are relatively
close to attaining the alternate primary standards.  It was also good
that we were able to identify where we disagree.  Ron has contacted
Lydia to let her know that the methods applied to places that are
relatively far from attainment of the alternate primary standards is an
issue that will require further discussion with management.

   I look forward to talking with you this Thursday about our benefits
methodology.  We'll get materials to you by the end of the day on
Wednesday.

   I have also collected answers to your questions that you asked at our
meeting November 1 on known costs and the base case modeling results. 
Our analysts are giving the answers a final review before they are sent
to you tomorrow. 

Let me know if I can be of any further assistance.

Thanks,

Janet
