## Abstract

EPA is approving revisions to the Wisconsin State Implementation Plan (SIP) addressing regional haze for the first implementation period, which extends through July 31, 2018. Wisconsin submitted its regional haze plan on January 18, 2012, with a supplemental submittal on June 7, 2012. EPA received comments on its proposed approval, addressing best available retrofit technology (BART) for a Georgia-Pacific Consumer Products, L.P. (Georgia-Pacific) paper facility and for power plants. EPA provides its response to these comments, and concludes that the Wisconsin regional haze plan satisfactorily addresses these requirements. Consequently, EPA is approving an administrative order establishing BART requirements for Georgia-Pacific into the Wisconsin SIP. More generally, EPA finds that Wisconsin has satisfied the applicable requirements for the State to remedy any existing and to prevent future impairment of visibility at mandatory Class I areas.
