Approval and Promulgation of Air Quality Implementation Plans; 
Indiana; Maintenance Plan Update for Lake County, Indiana for Sulfur 
Dioxide

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to approve a maintenance plan update for the 
Lake County, Indiana sulfur dioxide (SO2) maintenance area. 
This plan update demonstrates that Lake County will maintain attainment 
of the 1971 SO2 national ambient air quality standard 
(NAAQS) through 2025. This maintenance plan update satisfies section 
175A of the Clean Air Act (Act), and is consistent with the September 
26, 2005, approval of the State's redesignation request and maintenance 
plan for the Lake County, Indiana SO2 area.

SUPPLEMENTARY INFORMATION: In the Rules section of this Federal 
Register, EPA is approving Indiana's state implementation plan 
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 no adverse comments are received in response 
to this rule, no further activity is contemplated. If EPA receives 
adverse comments, the direct final rule will be withdrawn and all 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 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 Rules section of this Federal Register.

    Dated: August 20, 2013.
