ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R05-OAR-2009-0515; FRL-9232-4]


Approval and Promulgation of Air Quality Implementation Plans; 
Indiana; Clean Air Interstate Rule

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY:  EPA is proposing to approve a request submitted by the 
Indiana Department of Environmental Management (IDEM) on June 29, 2009, 
to revise the Indiana State Implementation Plan (SIP) under the Clean 
Air Act (CAA). The State has submitted amendments to the Indiana 
Administrative Code (IAC), which supplement Indiana's Clean Air 
Interstate Rule (CAIR), for which EPA granted limited approval as an 
abbreviated SIP on October 22, 2007. The State's June 29, 2009, 
submittal includes elements that EPA deems necessary in order for EPA 
to fully approve Indiana's CAIR SIP. This will allow a transition from 
an abbreviated SIP with limited approval to a full SIP with full 
approval under which the various CAIR implementation provisions would 
be governed by State rules rather than Federal Implementation Plan 
(FIP) rules. This action results in the withdrawal of the Indiana CAIR 
FIP concerning sulfur dioxide (SO2), nitrogen oxides 
(NOX) annual, and NOX ozone season emissions.

SUPPLEMENTARY INFORMATION: In the Final Rules section of this Federal 
Register, EPA is approving the State's SIP submittal as a direct final 
rule without prior proposal because the Agency views this as a 
noncontroversial submittal and anticipates no adverse comments. A 
detailed rationale for the approval is set forth in the direct final 
rule. If we do not receive any adverse comments in response to this 
rule, we do not contemplate taking any further action. If EPA receives 
adverse comments, we will withdraw the direct final rule, and will 
address all public comments in a subsequent final rule based on this 
proposed rule. EPA will not institute a second comment period. Any 
parties interested in commenting on this action should do so at this 
time. Please note that if EPA receives adverse comment on an amendment, 
paragraph, or section of this rule and if that provision may be severed 
from the remainder of the rule, EPA may adopt as final those provisions 
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 Final Rules section of this Federal Register.

    Dated: November 15, 2010.
