Approval and Promulgation of Air Quality Implementation Plans; 
Indiana; Particulate Matter 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 January 30, 2013, to revise 
the Indiana State Implementation Plan (SIP) for particulate matter 
under the Clean Air Act. This submission contains the 24-hour fine 
particle National Ambient Air Quality Standards (NAAQS) promulgated by 
EPA in 2006, and removes the annual coarse particle NAAQS that EPA has 
previously revoked. The submission also asks EPA to approve into the 
SIP certain Federally regulated criteria pollutant definitions and 
abbreviations.

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 4, 2013.

Regional Administrator, Region 5.
