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 SIP submittal proposes to revise Florida’s Maintenance Plan for the Hillsborough County Lead Maintenance Area to incorporate recent permit revisions for the EnviroFocus Technologies, LLC facility. These recent permit revisions increased the permitted refined lead production limit for the facility and incorporated other minor changes associated with the production increase. This SIP submittal also proposes to revise the attainment emissions inventory and projected future emissions inventories. The materials comprising DEP’s proposed SIP revision may be obtained through the Department’s website at https://floridadep.gov/air/air-business-planning/content/air-regulatory-projects or by contacting Hastings Read at Hastings.Read@Floridadep.gov.
