Pursuant to 40 CFR 51.102, the Department of Environmental Protection (DEP) announces the opportunity to offer comments or request a public hearing on a proposed revision to Florida’s Infrastructure State Implementation Plan (SIP) for the 2010 Sulfur Dioxide National Ambient Air Quality Standard (NAAQS) under the Clean Air Act (CAA). This SIP submission is solely meant to address the CAA Section 110(a)(2)(D)(i)(I) prongs 1 and 2 infrastructure elements. Florida satisfies these requirements because Florida does not significantly contribute to any out-of-state nonattainment or maintenance area as it relates to the 2010 Sulfur Dioxide NAAQS. The materials comprising DEP’s proposed Infrastructure SIP revision are accessible at the following website: https://floridadep.gov/air/air-business-planning/content/rules-and-regulatory-projects.
