BROWARD COUNTY STORAGE TANK CONSTRUCTION/CLOSURE MODIFICATION REQUIREMENTS
A Broward County Storage Tank Facility License (License) is required prior to building, erecting, operating, modifying, closing or replacing in whole or in part any storage tank system that is intended to store hazardous material in Broward County. The License approval process consists of the review of a Broward County Storage Tank Facility License application along with engineering drawings signed and sealed by a Professional Engineer (P.E.) registered in Florida. Steps taken to approve the application package are summarized in the following checklist.
SPECIAL NOTE: Broward County EPD has granted Variance Request VAR07-02 effective June 28, 2007, to gasoline dispensing facilities from having to install a Stage II Vapor Recovery System. This variance is granted to new facilities and existing facilities that will be upgrading their storage tank systems to meet the December 31, 2009 secondary containment deadline and that will be returned to operation after May 15, 2007. Storage tank facility owners should submit a letter along with their application confirming their intent not to install Stage II Vapor Recovery System as per the aforementioned variance requirements. Sections referring to Stage II Vapor Recovery Systems in the following document will not apply. A copy of the Variance Final Order may be obtained by clicking here or calling (954) 519-1229 or (954) 519-1432.
