E8-5288. Approval and Promulgation of Air Quality Implementation Plans; Indiana

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 July 20, 2007, as supplemented on December 19, 2007, to revise the Indiana State Implementation Plan (SIP). The submission revises the Indiana Administrative Code (IAC) by amending the definition of “References to Code of Federal Regulations,” to update of the references to the Code of Federal Regulations to refer to the 2006 edition. The rule revision also makes minor corrections to amend the definition of “nonphotochemically reactive hydrocarbons” or “negligibly photochemically reactive compounds,” and to amend the definition of “volatile organic compound” or “VOC.”

In the final rules section of this Federal Register, EPA is approving the SIP revision as a direct final rule without prior proposal, because EPA views this as a noncontroversial revision 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 these direct final and proposed rules, we do not contemplate taking any further action in relation to this proposed rule. If EPA receives adverse comments, we will withdraw the direct final rule and will respond to all public comments in a subsequent final rule based on this proposed rule. EPA will not institute a second comment period on this action. Any parties interested in commenting on this action should do so at this time.

DATES:

Comments must be received on or before April 17, 2008.

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 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 If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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: March 3, 2008.

Acting Regional Administrator, Region 5.
