## Abstract

The Environmental Protection Agency (EPA) is taking final action to approve a source-specific revision to the Arizona state implementation plan that addresses the best available retrofit technology requirements for the Cholla Power Plant (Cholla). The EPA finds that the state implementation plan revision fulfills the requirements of the Clean Air Act and the EPA's Regional Haze Rule. In conjunction with this final approval, the EPA is taking final action to withdraw the federal implementation plan provisions applicable to Cholla. This also constitutes our action to address petitions for reconsideration granted by the EPA related to Cholla.
