Read the Compliance GuideFlorida Tank Regulatory Overview
The Florida Department of Environmental Protection (DEP) regulates both underground storage tank (UST) and aboveground storage tank (AST) systems that store petroleum or petroleum products. Florida's storage tank compliance program is one of the most comprehensive in the Southeast, covering registration, release detection, periodic integrity testing, and certified operator requirements.
These regulations apply to all owners and operators of regulated UST and AST systems in the state of Florida. Failure to comply can result in fines, enforcement actions, and environmental liability. Compliance obligations are codified in Chapter 62-761, F.A.C. (USTs) and Chapter 62-762, F.A.C. (ASTs), most recently amended effective June 25, 2023.
Key Compliance Requirements
Florida DEP requires UST and AST owners and operators to meet the following compliance obligations for registration, release detection, testing, and maintenance.
Registration Fees & Placards
Storage tank registration fees are due to the Florida Department of Environmental Protection (DEP) each year by July 1. A valid placard must be printed and displayed at your facility — you cannot legally receive motor fuel without one.
Financial Responsibility
Owners of USTs and ASTs storing petroleum or petroleum products must demonstrate and maintain financial responsibility (FR), such as insurance, for pollution liability. FR must be maintained until tanks are properly closed and your Closure Report has been approved by the Department.
Release Detection — Visual Inspections
Visually inspect all storage tank system components every month (not to exceed every 35 days) and document your findings. Records must be maintained for 3 years. Piping and dispenser sumps using electronic devices must also be visually inspected every 6 months.
Release Detection — Electronic Devices
Electronic release detection devices must be inspected for proper operation every month (not to exceed every 35 days). Alarm history, sensor status, and testing results must be printed and kept for 3 years. If the device lacks print capability, a manual log must be maintained.
Annual Operability Testing
All release detection devices and overfill protection equipment must be tested for operability annually at intervals not exceeding 12 months. Owners must designate a primary overfill device, register it with the Department, and ensure secondary devices do not interfere with the primary.
Periodic Integrity Testing
Single-walled spill containment systems must be tested annually (not to exceed 12 months). Piping sumps, dispenser sumps, and double-walled spill containment systems require testing every 3 years (not to exceed 36 months). Hydrostatic testing ensures containment integrity and environmental protection.
Incident Response
If a release or discharge may have occurred, incident investigations must begin within 24 hours. The incident must be reported to the contracted county within 72 hours. All positive alarm responses must be investigated and records maintained for Department inspection.
Repairs, Operation & Maintenance
All storage tank system equipment must be maintained in sound operational condition. Corrosion of metal components must be minimized through periodic maintenance. Water in excess of one inch or any regulated substances in secondary containment must be removed within 72 hours.
Overfill Prevention
Owners must designate a primary overfill protection device, register it with the Department, and ensure secondary devices do not interfere with the primary. Overfill prevention equipment must be tested for operability annually at intervals not exceeding 12 months.
Spill Buckets & Sumps
Spill buckets and containment sumps must be kept clean and free of debris, water, and product at all times. Single-walled spill containment systems must be tested annually. Piping sumps, dispenser sumps, and double-walled spill containment systems require hydrostatic integrity testing every 3 years.
Cathodic Protection
Steel tanks and piping must have cathodic protection systems to prevent corrosion. Cathodic protection must be tested within 6 months of installation and every 3 years thereafter. Impressed current systems require regular rectifier inspections with records maintained.
Certified Operators
Each UST facility must have Class A, Class B, and Class C operators who are trained and certified. A Class A, B, or C operator must be present at UST facilities during all times of operation unless the facility is unmanned. Class B operators can train Class C operators.
