ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R07-OAR-2007-1180; FRL-8535-8]

 
Approval and Promulgation of Implementation Plans; State of Iowa

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: EPA proposes to approve the State Implementation Plan (SIP) 
revision submitted by the state of Iowa to demonstrate that the state 
meets the requirements of Section 110(a)(1) and (2) of the Clean Air 
Act (CAA). Section 110(a) of the CAA requires that each state adopt and 
submit a SIP for the implementation, maintenance and enforcement of 
each NAAQS promulgated by the EPA and is commonly referred to as an 
infrastructure SIP. In 1997, EPA promulgated the 8-hour ozone primary 
and secondary NAAQS. A revision to Iowa's SIP detailing how the state 
plans to ensure that the revised ozone standard is implemented, 
enforced, and maintained in Iowa was submitted on June 15, 2007. The 
submittal addressed all the elements of the October 2, 2007, guidance 
issued by the Office of Air Quality and Planning Standards with respect 
to infrastructure SIPs.

DATES: Comments on this proposed action must be received in writing by 
April 3, 2008.

SUPPLEMENTARY INFORMATION: In the final rules section of the Federal 
Register, EPA is approving the state's SIP revision as a direct final 
rule without prior proposal because the Agency views this as a 
noncontroversial revision and anticipates no relevant adverse comments 
on this action. A detailed rationale for the approval is set forth in 
the direct final rule. If no relevant adverse comments are received in 
response to this action, no further activity is contemplated in 
relation to this action. If EPA receives relevant adverse comments, the 
direct final rule will be withdrawn and all public comments received 
will be addressed in a subsequent final rule based on this proposed 
action. EPA will not institute a second comment period on this action. 
Any parties interested in commenting on this action should do so at 
this time. Please note that if EPA receives adverse comment on part of 
this rule and if that part can be severed from the remainder of the 
rule, EPA may adopt as final those parts of the rule that are not the 
subject of an adverse comment. For additional information, see the 
direct final rule which is located in the rules section of this Federal 
Register.
