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.2 Please let me know if you have questions.

Thanks, Ben

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
