The Environmental Protection Agency (EPA) is approving a regional haze State Implementation Plan (SIP) revision submitted by the Florida Department of Environmental Protection (FDEP) on October 8, 2021, and supplemented on June 14, 2024, and October 28, 2024, as satisfying applicable requirements under the Clean Air Act ("CAA" or "Act") and EPA's Regional Haze Rule (RHR) for the program's second planning period. Florida's SIP submissions were submitted to address the requirement that states must periodically revise their long-term strategies for making reasonable progress toward the national goal of preventing any future, and remedying any existing, anthropogenic impairment of visibility, including regional haze, in mandatory Class I Federal areas (hereinafter referred to as "Class I areas"). These SIP submissions also address other applicable requirements for the second planning period of the regional haze program. EPA is taking this action pursuant to sections 110 and 169A of the Act.
