          - 40 CFR Part 52
          - [EPA-R05-OAR-2008-0501; FRL-8698-8]

# 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 May 22, 2008, to revise the Indiana State Implementation Plan (SIP). The submission revises the Indiana Administrative Code (IAC) by amending and updating the definition of “References to Code of Federal Regulations,” to refer to the 2007 edition.

                        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.

Comments must be received on or before September 3, 2008.
