Scott,

Please see below for one more small comment from the interagency review. Thanks. 

We have one comment on page 81.  EPA’s revised language indicated that they “attempted” to partially 
revoked the standard  for transportation conformity purposes.  We disagree with the word “attempted” 
as it implied the partial revocation was not a final decision.  In fact, on May 21, 2012, EPA published the 
final Classifications Rule for the 2008 ozone NAAQS, effective July 20, 2012, which partially revoked the 
1997 ozone NAAQS for conformity purposes.  DOT has implemented the transportation conformity 
requirements based on this 2012 final.  
 
We proposed to change the following sentences (on p.81) to read: 
 
“The D.C. Circuit ruled that the EPA violated the CAA when it attempted to partially revoked the 1997 
ozone NAAQS for transportation conformity purposes only in the Classifications Rule for the 2008 ozone 
NAAQS. The attempted partial revocation would have become had been in effect effective on since July 
20, 2013, 1 year after the effective date of designations for the 2008 ozone NAAQS. (77 FR 30160)”
