- contains edits from OMB_clean rlso.docx

Aaron,

The attached redlined version of the Ozone SIP Requirements SRR contains the following edits:
1)	Edits resulting from the written comments OMB provided to EPA. These are labeled with 
comment bubbles as:
a.	OMB general comments,
b.	OMB specific comments, and
c.	OMB typographical comments;
2)	Nearly all edits necessary to reflect the results of the recent NRDC decision regarding the 
2012 ozone implementation rule’s treatment of attainment dates and revoking the 1997 
NAAQS for purposes of transportation conformity only (see note below);
3)	Edit to Table 1 acknowledging that another nonattainment area has been redesignated to 
attainment
4)	Edits resulting from discussion with OMB and inter-agency partners on 1/23/15 
regarding EPA’s responses to the prior written comments.
5)	Edits from an additional December 2014 review by EPA OGC staff.
Note: This version does not yet contain a new preamble (perhaps section III.Y) and 
accompanying regulatory text changes to 40 CFR 51.1103 to establish the attainment deadlines 
consistent with the recent NRDC decision. That language will be added after further internal 
EPA discussions with counsel.
