Pb RIA Chapters for OMB









Heidi -- attached are all the current chapters of the Pb RIA.  We
believe we have incorporated all of your comments, with the exception of
cascading new alternative C-R functions and new alternative blood Pb
ratios throughout the analysis.

You'll note in particular that we have incorporated the alternative
standard of 0.50 ug/m3 throughout.  Also please note changes to the
front pages of chapter 4, 5, 6, 7, and the Executive Summary to add
caveats.  

Thanks.

-- Kathy
