**AGENCY :**  Environmental Protection Agency (EPA).

**ACTION :**  Proposed rule.

**SUMMARY :**  The Environmental Protection Agency (EPA) is proposing to approve a Texas State Implementation Plan (SIP) revision for control of volatile organic compound (VOC) emissions from fugitive sources that was submitted to EPA on July 2, 2010. The SIP revision allows for a voluntary alternative work practice to detect fugitive emission leaks using optical gas imaging instruments under the EPA federal Leak Detection and Repair (LDAR) requirements. The EPA adopted through rulemaking the use of this voluntary alternative work practice for federal leak detection and repair of fugitive emissions sources. EPA has evaluated the SIP revision and determined that it is consistent with the federal LDAR regulations. EPA is approving this action under Section 110 of the Clean Air Act.

**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 relevant adverse comments are received in response to this action no further activity is contemplated. If EPA receives relevant adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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.

**Approval of Other Solid Waste Incinerator Units State Plan for**  **Designated Facilities and Pollutants: Indiana** 

**AGENCY :**  Environmental Protection Agency.

**ACTION :**  Proposed rule.

**SUMMARY :**  The Environmental Protection Agency (EPA) is proposing to approve, through direct final procedure, Indiana’s State Plan to control air pollutants from ‘‘Other Solid Waste Incineration’’ (OSWI) Units. The Indiana Department of Environmental Management submitted the State Plan on November 27, 2007, following the required public process. The State Plan is consistent with Emission Guidelines promulgated by EPA on December 16, 2005. This approval means that EPA finds that the State Plan meets applicable Clean Air Act requirements for OSWI units for which construction commenced on or before December 4, 2004. Once effective, this approval also makes the State Plan Federally enforceable.
