Hi Chad, Per your question about which pages have the “blue comment bubble” edits, a list is below. I added “ 6-3-15: ” at the beginning of each comment so they’re easier to find . I also noticed that the formatting wasn’t quite right on a few tables, so I fixed those, but it repaginated the do cument a bit. The list below denotes which pages h ave the comments and the tables that I fixed.

Blue comment bubbles are on the following pages:

- 16-17

- 90-93

- 140

- 156

- 159 I also reformatted the TofC, and the tables on pp.1 31 and 133-134 to be single-spaced.

Thanks, Tia

Hi Chad,2 Please see attached file for EPA’s edits in respons e to the discussion from yesterday’s call -- our e dits made in response to the comments are highlighted in blue comment bub bles. We also made an additional edit on the signa ture page only to add a heading that is now required on signature pages for EPA rules.

Thanks, Tia

Ben, Attached are the latest round of EO 12866 inter agency comments. The comments can be identified by searching for EO13563 in the comment bubbles. We accepted the re dline from your most recent passback so that only r edline changes would be due to suggested edits. We left t he previous comment bubbles though. Let me know if you would like to discuss. Chad

Hi Chad,

I’m attaching the next iteration of the aircraft pa ckage. A few notes:

• This version responds to the 5/8 comments, and inco rporates the new Section G edits as well.

• We are attaching three supporting documents that yo u requested.

• In addition to responding to specific interagency c omments in this 2 nd round, we have updated sections I, II, and V (most updates are in section V) with 2013 GHG inv entory numbers, which are from the 2015 EPA GHG & S inks report just published on April 15, 2015. Note, in the first round of OMB review, OMB asked, “has EPA released the inventory for 2013 and 2014 yet – if so, consid er including in this discussion.” We responded tha t since the 2013 inventory numbers were just released, we need time to update the inventory numbers throughout the preamble (particularly section V), and OMB was okay with this response. Subsequently, we have now fin ished updating these inventory numbers.

Please let me know if you have questions.

Thanks, Ben

Tia, Attached are the suggested EO 12866 interagency comments pertaining to just Section G of the draft rule. The attached document does not contain the comments tha t I sent over on 5/8 in the email below. When EPA responds, please use the document from 5/8 and substitute Sec tion G from the document attached to this email. T he suggested changes in Section G can be identified by green hig hlighted text in the body of the email. Please let me know if you have any questions. Thanks, Chad
