Proposed Revision to the Hillsborough County Lead (Pb) Maintenance Plan

The Department of Environmental Protection (DEP) is proposing a revision to the DEP’s Maintenance State Implementation Plan (SIP) for the Hillsborough County Lead Maintenance Area under the federal Clean Air Act (CAA). On September 11, 2018, the U.S. Environmental Protection Agency (EPA) redesignated the Hillsborough County Lead Nonattainment Area to attainment, effective October 11, 2018, and approved Florida’s proposed Maintenance Plan into Florida’s SIP that ensures that the Hillsborough County Lead Maintenance Area will continue to attain the 2008 Lead National Ambient Air Quality Standard (NAAQS) through 2029.

As part of Florida’s Maintenance Plan, the DEP requested that the permit conditions applicable to the EnviroFocus facility for the pollutant lead that were approved into the Hillsborough County Lead Nonattainment Area SIP be carried over and incorporated into the Hillsborough County Lead Maintenance SIP.

On September 13, 2019, the EnviroFocus facility submitted a complete permit application that requested, among other things, an increase in the permitted refined lead production limit for the facility. On November 6, 2019, the DEP issued a final permit to EnviroFocus that increases the refined lead production limit for the facility from 150,000 tons per year (TPY) to 200,000 TPY. This SIP submittal proposes to update the Hillsborough County Lead Maintenance Plan to incorporate the production increase for the EnviroFocus facility, incorporate other minor changes associated with the production increase, and revise the attainment emissions inventory and projected future emissions inventories. No other changes to the DEP’s currently approved Maintenance SIP are being proposed, including the contingency measures that are part of the current Hillsborough County Lead Maintenance SIP. The DEP will continue to implement those contingency measures.
