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.

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.
