Aaron: here is the redline. I’ll get you a clean version as soon as I get it.

One note: we sent you a version on July 2 that represented our first attempt to incorporate the 

interagency comments. In case you already looked at that version, we wanted to show the additional 

changes we made since then in a different color. This document attempts to do that. However, Word 

appears to be confused sometimes when the edit appears in both versions, so please know that we are 

aware of the double-wording and it will not show up in the clean version.

One other note: I observed today that this version does not include a citation to the new memo we 

recently developed, so I will ensure that such a citation is added to the clean version I send you.

Yes. Please send over both a clean and redline-strikeout version of the newest version of the 

preamble. Thank you very much.

Hi Aaron. Attached is the draft memo for your review. Let me know when you want to share with us 

your reaction to it. I trust it addresses your suggestion.

I also just want to flag for you that we have made a couple of minor edits to the preamble and rule since 

the version I sent you on July 2. Very minor stuff to reflect our conversation the week of July 6 and 

other edits to polish up our responses to the interagency comments. Would you like me to send over 

that version as well?

Thanks.

Hi Aaron. Thank for your comments. In Megan’s absence, I am forwarding to you our suggested edits to 

the preamble in response to the comments. We’d like to set up some time ASAP to go over these with 

you and anyone else you think should be included. I will note that the edits address virtually all of the 

comments, but there are one or two remaining comments we’d like to discuss with you when we meet, 

so we can determine whether and how best to address them. Let’s talk early next week about a time to 

get together and let me know in the meantime if you have any questions. Hope you have a wonderful
