Pursuant to 40 CFR 51.102, the Department of Environmental Protection (DEP) announces a public hearing and opportunity to offer comments on a proposed revision to Florida’s State Implementation Plan (SIP) under the Clean Air Act. This proposed SIP revision consists of a request to redesignate the portion of Hillsborough County that is designated as “nonattainment” with respect to the 2008 revised lead national ambient air quality standard (NAAQS) to “attainment” and a request to approve an associated maintenance SIP that will ensure the continued attainment of the 2008 lead NAAQS in the area.
