Approval and Promulgation of State Plans for Designated Facilities and Pollutants; Indiana; Control of Landfill Gas Emissions From Existing Municipal Solid Waste Landfills

The EPA is approving the Indiana State Plan submittal for implementing the Municipal Solid Waste (MSW) Landfill Emission Guidelines. The State submitted this plan on September 30, 1999 in accordance with requirements found in the Clean Air Act (CAA) and in the Code of Federal Regulations for adoption and submittal of State plans for designated facilities. The plan establishes performance standards for existing MSW landfills and provides for the implementation and enforcement of those standards. The EPA finds that Indiana's plan for existing MSW landfills adequately addresses all of the Federal requirements applicable to such plans. EPA's approval of the State's MSW Landfill Plan also includes rules submitted to EPA on November 21, 1995, and February 14, 1996, as volatile organic compound control measures. EPA approved the rules as part of the Indiana SIP on January 17, 1997. In this action, EPA is incorporating the rule revisions into the Indiana MSW Landfill Plan.
