- of

- inter est laws that pertain to

, Chair of C ASAC

.

Dr. Samet welcomed everyone and indica ted that the purpose of the meeting was to review the

draft letter on EPA‟s ISA 2 and that the goal was to discuss any substantive issues the members

had on the letter. He welcomed and introduced a new member to CASAC, Dr. Ana Diez

- Roux.

Dr. Diez

- Roux state d that she was a professor of epidemiology at the University of Michigan and

has expertise in air issues. There were not any public comments, so Dr. Samet turned t he meeting

over to Dr. Chris Frey, chair of the CASAC Lead Review Panel, to go over the lette r. The

meeting proceeded according to the agenda 3

.

Letter to the Administrator

D r

. Frey went through the letter, summarizing the Panel‟s comments and recommendations. One

member had a comment about the Panel‟s recommendation on lines 19

- 21 on page 2 rega rding

the weight of evidence assessment of specif i c health endpoints vs. the broad assessment of

impacts on whole organ systems. It was agreed that edits will be made to the text to clarify the

Panel‟s recommendation.

There was discussion regarding the re iteration of CASAC‟s previous advice on deve loping a new

sampler for lead and where things currently stood with EPA‟s development of a new sampler. It

was not clear where things stood with EPA‟s development, and it was agreed that the ISA was

probably not the right place to discuss it.

There was discussion regarding the Panel‟s comments and recommendations pertaining to

susceptibility and vulnerability. There was agreement that the advice needs to be consistent with

prior CASAC advice on susceptibility and vulnerability given during the review of the Ozone

ISA. Dr. Samet and Dr. Frey agreed to work on language to make the advice in this letter

consistent with prior CASAC advice.

Regarding ecological effects, one member mentioned that there needed to be a c lear

recommendation regarding the REACH data on page 5, line 9. It was agreed that language would

be added to clarify the recommendation.

Consensus Response to Charge Questions

Dr. Frey went through the consensus responses to the charge questions. It was agreed that lines

28

- 31 on page A

- 3 would be deleted because it created confusion and did not add much value to

the letter. One member suggested that lines 22

- 24 on page A

- 8 be deleted, but Dr. Frey stated3

that it was a specific recommendation from the Pa nel, so it was agreed to keep the language.

There was discussion regarding lines 6

- 7 on page A

- 18 and it was agreed to clarify the language

to be less general and more specific.

Dr. Samet discussed next steps and action items. With the business concluded, the Designated

Federal Officer adjourned the meeting at 11:3 0 A M ET

.
