Updated version of lead NAAQS NPR 









Heidi, 

Attached are updated clean and redline versions of the draft lead NAAQS
NPR.   This is our second informal submission to you.   As we discussed,
this redline does not address all the comments you have faxed to me.  
We have addressed some of them and intend to address others as we
continue to revise the package.  To the extent there are major
substantive comments which we feel we cannot address in the manner
suggested by the commenter, we will plan to discuss those with you next
week.   In addition, while we have made changes to the section on the
Administrator's provisional conclusions on level, including deleting
most of the discussion of the adapted 1978 framework, we have not yet
made comparable changes throughout other sections of the preamble. 
Similarly, although we have revised the section on air-to-blood ratios,
we have not yet made corresponding edits to the subsequent
evidence-based considerations sections where these ratios are mentioned.
  We intend to work on these sections during the next couple of days.  

Please call me if you have any questions.  

Lydia
