          - 40 CFR Part 52 
          - [R05-OAR-2005-IN-0007; FRL-7999-4] 

# AGENCY:

Environmental Protection Agency (EPA). 

# ACTION:

Proposed rule. 

# SUMMARY:

                        EPA is proposing to approve Indiana's April 8, 2005, submittal which revises existing sulfur dioxide (SO2) emission limits for sources in Dearborn County. On April 8, 2005, Indiana submitted its final rule as published in the Indiana Register. Indiana held public hearings on the submittal on May 5, 2004 and October 6, 2004. Indiana is requesting that EPA approve the revisions to Indiana's SO2                         rule for Dearborn County, which removes obsolete rule language and updates information for sources listed in the rule. These revisions will not result in an increase in SO2                         emissions in Dearborn County because no emission limits were increased.                     

                        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.

## II. What Action Is EPA Taking Today? 

                    EPA is proposing to approve revisions to Indiana's SO2                     SIP for specified existing stationary sources located in Dearborn County, Indiana. The SIP revisions amend 326 IAC 7-4-13, by removing obsolete rule language for the Indiana Michigan Power Tanners Creek Station. The SIP revision also updates information for other companies listed in 326 IAC 7-4-13, including adding source identification numbers. The amendments to this rule are minor, and will not result in an increase in SO2                     emissions in Dearborn County because no emission limits were increased.
