Storage Tank Modification Requirements

​Broward County Storage Tank Construction/Closure Modification Requirements

A Broward County Storage Tank Facility 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. Aboveground storage tank systems with capacities greater than 550 gals and underground storage tank systems with capacities greater than 110 gals are subject to Broward County Chapter 27, Article X, Storage Tanks regulation.

Special Note: Effective 2/26/2013, Chapter 27, Pollution Control, of the Broward County Code of Ordinances (Code), Article X, Storage Tanks, no longer requires Stage II Vapor Recovery (Stage II) Systems be installed at Gasoline Dispensing Facilities (GDF). However, GDF owners or operators with existing Stage II systems must either continue to maintain and operate their systems in accordance with the Ordinance or file for a License Modification approval/permit to close, remove, or decommission their Stage II system in accordance with the Code. It shall be prohibited to dismantle, remove, disconnect, cease to operate, close or decommission Stage II systems without applying for, and obtaining a License Modification approval prior to performing any of the aforementioned activities. 

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.) licensed in the state of Florida. Steps taken to approve the application package are summarized in the following checklist. This checklist is created to serve as a guide to the owner/operator, contractor, or engineer through the storage tank modification/construction approval process.

Storage Tank Facility License Application​

  • As part of the latest electronic Permit (ePermits) release, Storage Tank customers can now submit applications for new storage tank facilities or modifications to currently licensed facilities. This service can be accessed at any time to submit applications, upload documents, and pay fees by clicking on the following weblink: http://www.broward.org/ePermits/Pages/Default.aspx. 
  • Following are alternative and other steps needed to complete your License application.

  • A License application package, consisting of the Storage Tank Facility License application and 4 sets of signed and sealed engineering plans, must be submitted to the Environmental Permitting Division (EPD)  for approval prior to commencing storage tank construction, closure or modification activities.
