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.
