Thanks - were you able to track down an electronic copy of the tables

that you sent to Art in July?  Thanks.  Margo

Subject: Fw: Response to your follow-up questions on contribution of

ranges to nonaccidental mortality associated with ozone just meeting

current standard AND Two Ozone public comments

As we discussed earlier today, here's the email with the files that

Lydia sent in the Spring with tables showing the contribution of ranges

to nonaccidental mortality associated with ozone just meeting the

current standard.

You also requested the docket id's for two of the public comments.  I

have the docket id for the UARG, October 9, 2007 comments and it is:

EPA-HQ-OAR-2005-0172-4183.  I haven't located the docket id for the

Univ. of Rochester report, but I do have an electronic file for this

report, which I've attached below.

Amy, Art and Rob,

Please find attached Harvey's response to Art's question about the

contribution of different levels of ozone to nonaccidental mortality.

I hope this answers your questions.  Please let me know if you have

further questions about this material.

Rob, as to our Friday meeting that we discussed this morning, I learned

that Harvey will not be available on Friday.  I don't know if any of

your follow-up questions are about the risk assessment, but if they are,

we will have to postpone those to next week when Harvey is available, or

move the meeting back to Thursday.  If none of the questions are about

the risk assessment, we should be able to proceed with our Friday

meeting as planned.   Thanks.

Lydia

Lydia,

   In response to the request from OMB made during the meetings arranged

   by CEQ, attached are two Excel files that contain tables showing the

   estimated number of cases, and associated 95% credible intervals, for

   nonaccidental mortality based on the risk assessment broken down by

   the number of cases estimated to occur due to exposure to different

   24-hr O3 intervals associated with just meeting the current 8-hr

   standard in 12 urban areas.  The tables, and Figure 5-15a,b in the

   Staff Paper, present risks broken down by 24-hr intervals because the

   epidemiological studies report effects related to the average of the

   24-hr concentrations across the monitors in an urban area.  To

   provide some perspective on the daily maximum 8-hr average that would

   be associated with each 24-hr interval, we note that the 8-hr daily

   maximum concentrations at the highest (i.e., design value) monitor

   are, on average, roughly twice the 24-hr average O3 concentrations

   provided in these tables.  For example, the 0.03-0.04 ppm 24-hr range

   in the table roughly corresponds to the highest monitor in the urban

   area observing a daily maximum 8-hr average in the range 0.06-0.08

   ppm.

ranges_current std based on 2002 data-5-4-07.xls)(See attached file:
