Subject

 draft memo to the docket containing new IQ calculations for the Pb
NAAQS RIA

Heidi, here is the draft memo containing the 2 new C-R functions.   It
is short and sweet.   We provide the detailed results for the 2
functions and also include a graphical comparison of the results with
the C-R function used in the body of the RIA.   We will provide cross
reference to this memo in chapter 5 of the RIA.   Please let me know if
you have any comments on this memo.   I look forward to talking to you
on Monday.
