[[Page 26225]]

the Rules and Regulations section of this Federal Register, we are 
approving these local rules in a direct final action without prior 
proposal because we believe these SIP revisions are not controversial. 
If we receive adverse comments, however, we will publish a timely 
withdrawal of the direct final rule and address the comments in 
subsequent action based on this proposed rule. Please note that if we 
receive adverse comment on an amendment, paragraph, or section of this 
rule and if that provision may be severed from the remainder of the 
rule, we may adopt as final those provisions of the rule that are not 
the subject of an adverse comment.
    We do not plan to open a second comment period, so anyone 
interested in commenting should do so at this time. If we do not 
receive adverse comments, no further activity is planned. For further 
information, please see the direct final action.

    Dated: March 31, 2011.
Jared Blumenfeld,
Regional Administrator, Region IX.
