Pursuant to the Federal Clean Air Act (CAA or the Act), the Environmental Protection Agency (EPA) is proposing to approve a portion of the revision to the Arkansas State Implementation Plan (SIP) that addresses certain requirements of the CAA and the EPA's regional haze rules for the protection of visibility in mandatory Class I Federal areas (Class I areas) for the first implementation period. The EPA is proposing to approve the portions of the SIP revision addressing the best available retrofit technology (BART) requirements for sulfur dioxide (SO<INF>2</INF>), particulate matter (PM) and nitrogen oxide (NO<INF>X</INF>) for seven electric generating units (EGUs) in Arkansas. The EPA is also proposing to approve the determination that no additional controls at any Arkansas sources are necessary under reasonable progress; calculation of the revised reasonable progress goals (RPGs) for Arkansas' Class I areas; certain components of the long-term strategy for making reasonable progress; the clarification that both the 6A and 9A Boilers at the Georgia-Pacific Crossett Mill are BART-eligible; and the additional information and technical analysis in support of the determination that the Georgia-Pacific Crossett Mill 6A and 9A Boilers are not subject to BART. In conjunction with our proposed approval of portions of the SIP revision, we are proposing to withdraw the corresponding federal implementation plan (FIP) provisions established in a prior action to address regional haze requirements for Arkansas.
