When the toxicokinetic component (1) is combined with the toxicodynamic component (1), then the overall value for this factor is 1, but could be as low as 0.3. Combining these factors results in a conservative MOE of 1000, which would be applied to the point of departure dose of 1.4 mg'kg/day (LED10) resulting in a risk specific dose of 1.4 pg/kg/day. Using default assumptions about drinking water consumption and body weight, a risk specific drinking water level would be 50 pg/L.

S T A f i T T s P e f o ^ m o b J 122 1 A. They may have the table and not the 2 e-mail. Are you asking -3 Q. Whatever they have. Whatever they have. 4 So this was a one-page chart similar to 5 Exhibit 11 but all the columns are filled in by 6 TERA? 7 A. This is multi-page. 8 Q. What were the numbers TERA picked? 9 A. I don't recall. 10 Q. Do you recall what their total screening 11 level number was for drinking water? 12 A. I don't recall. I am not even positive 13 if I had them take it to a screening level, only 14 to the reference of filling in this table. This 15 table, as you see, doesn't have a column for 16 screening level; it stops at RSD. 17 Q. Do you know1whether the numbers were 18 higher or lower than those that the CAT Team 19 came up with on May 6th and 7th? 20 A. I don't recall. 21 Q. You don't recall what generally, even 22 generally speaking what the range of the numbers 23 were in comparison to what -24 A. No. I just briefly looked over it, and 000018 123 1 as I thought about it it made more sense to me 2 to -- and I discussed it with TERA. 3 Q. Who at TERA? 4 A. Andy Maier and Joan Dollrhide probably. 5 I am positive Andy Maier. Sometimes Joan was 6 also on the phone and sometimes not. 7 But I told them that I wanted them to 8 lead us through the process. 9 And at the meeting I told them that they 10 could make suggestions. And it would more, that 11 that table that was filled would be, not 12 presented in the sense of given to the people at 13 the meeting but that TERA could make 14 suggestions. 15 But as the meeting proceeded it became 16 clear that TERA, we were leading, but 10 17 opinionated toxicologists took the discussion in 18 hand and came up with the numbers themselves. 19 And we were, again, in agreement. And I let it 20 go forward that way. 21 Q. So you don't remember any, even remotely 22 what any of the values were that TERA had come 23 up with on its own? 24 A. No. 124 1 Q. Do you know, for example, what they had 2 picked, whether they picked uncertainty factors 3 of 10 for any of the UFLs, UFSs or UFDs on the 4 chart? 5 A. I don't remember the table at all, I 6 mean the numbers that are in it at all. As I 7 said, I simply scanned it and thought about how 8 would, how did I want to set this up, would that 9 influence the other people. I wanted no 10 influence at all. I wanted each and every one 11 of them's opinion. So I didn't want to 12 influence their opinions. So I made the 13 decision -- Of course, TERA would lead us 14 through it. That's their job. If they wanted 15 to make recommendations they could. But quickly 16 the group was very opinionated and made their 17 own decisions quite quickly. 18 Q. Do you recall whether the opinions that 19 the group came up were different from what TERA 20 had suggested? 21 A. How could I recall when I don't remember 22 what TERA suggested. 23 Q. You got this chart from TERA and you 24 golooked at it. Was there something about it 125 1 that caught your eye that made you think that we 2 ought to let the CAT Team do this instead of 3 what TERA has come up with? 4 A. No. Just the fact that those 5 uncertainty factors were already filled in. And ' 6 I didn't want the team to feel like the decision 7 was already made. It should be a time 8 decision. So it implied, if I would have sent 9 it to them,, that the decision had already been 10 made and we were simply reviewing what TERA had 11 already done. 12 I wanted it to be a group decision, so 13 that everyone's opinion mattered, everyone 14 ' contributed. We reach a consensus. Hopefully, 15 it is not a consensus then majority rules. 16 Q. Did anybody else get the preliminary 17 chart that TERA had prepared and e-mailed to 18 you? 19 A. No. 20 Q. Did you ask TERA to do anything with 21 that chart or e-mail? 22 A. Just to remove the uncertainty factors 23 and make one without the minute. 24 Q. Did you ask them to destroy that chart ATTACHMENT G 4 of 4 v 000921
