Approval and Promulgation of Air Quality Implementation Plans; 
Indiana; Sulfur Dioxide and Nitrogen Dioxide Ambient Air Quality 
Standards

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to approve a request submitted by the Indiana 
Department of Environmental Management on April 15, 2011, and 
supplemented on January 30, 2013, to revise the Indiana state 
implementation plan (SIP) for nitrogen dioxide (NO2) and 
sulfur dioxide (SO2) under the Clean Air Act. This submittal 
consists of revisions to the Indiana Administrative Code that amend the 
national ambient air quality standards (NAAQS) for NO2 and 
SO2 to be consistent with the NAAQS that EPA promulgated in 
2010.

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: April 29, 2013.

Regional Administrator, Region 5.
