Air Plan Approval and Air Quality Designation; Florida: Redesignation of the Hillsborough County Lead Nonattainment Area to Attainment

On March 26, 2018, the State of Florida, through the Florida Department of Environmental Protection, submitted a request for the Environmental Protection Agency (EPA) to redesignate the Hillsborough County lead Nonattainment Area (``Hillsborough Area'' or ``Area'') to attainment for the 2008 lead National Ambient Air Quality Standards (NAAQS) and to approve an accompanying State Implementation Plan (SIP) revision containing a maintenance plan for the Area. The Hillsborough Area is comprised of a 1.5 kilometer (km) radius in Tampa, Florida, surrounding the Envirofocus Technologies, LLC facility (Envirofocus). EPA is taking final action to determine that the Hillsborough Area is attaining the 2008 lead NAAQS; to approve the SIP revision containing the State's maintenance plan for maintaining attainment of the 2008 lead standard and to incorporate the maintenance plan into the SIP; and to redesignate the Hillsborough Area to attainment for the 2008 lead NAAQS.
