Compliance and Preventive Maintenance
Maintenance plays a role in every aspect of operations, from ensuring the proper function of the tank’s components to ensuring the quality of the product. And of course, preventative maintenance will also help prolong the lifespan of the tank itself.
Don Wood Inc. can conduct a complimentary site evaluation. We will develop a schedule for the required testing and inspection to ensure your site is in compliance with the Florida DEP regulations. Our technicians are highly trained and certified by most of the release detection equipment manufacturers.
Fuel storage tanks require regular maintenance and can be susceptible to many problems. Specifically:
Aboveground storage tanks are susceptible to microbial growth due to moisture collection
Underground storage tanks are often contaminated by groundwater as a result of plumbing issues or inclement weather
Fuel in diesel generator tanks will degrade over time, and the tanks require regular maintenance
Compliance and Preventive Maintenance
The Department of Environmental Protection (DEP) conducts periodic inspections of regulated facilities to ensure aboveground and underground tanks are properly maintained, tested, and inspections are being conducted by the fuel tank operators. Facility owners and operators should conduct these testing and inspections within the required time frame to stay in compliance.
How often do I need to test my underground and aboveground storage tanks?
Generally, fuel tanks should be inspected monthly by a certified operator and the released detection equipment should be tested by a third party annually according to Chapter 62-761, F.A.C. for Underground Storage Tanks (USTs) and Chapter 62-762, F.A.C. for Aboveground Storage Tanks (ASTs).
The DEP requires the following components to be inspected to ensure proper operation and to prevent leaks or spills of regulated products:
Release Detection – Electronic Devices
Electronic release detection devices shall be inspected for proper operation every month. A record or summary of the alarm history, sensor status, and testing results shall be printed from the device and kept for 3 years. If the device does not have the print capability, then a manual log must be maintained.
Release Detection – Emergency Generators
Release detection is now required for underground storage tank systems that store the fuel for use by emergency power generators.
Annual Operability Testing – Release Detection Devices & Overfill Protection Equipment
All release detection devices must be tested for operability annually at intervals not exceeding 12 months to ensure proper operation and be registered with the Department.
Effective October 13, 2019, owners and operators must designate a primary overfill device. Secondary, overfill devices cannot interfere with the proper operation of the designated primary device. The designated primary overfill device must be registered with the FDEP and perform annual operability testing at intervals not exceeding 12 months.
Periodic Integrity Testing
Periodic testing of storage tank system components shall occur according to the following schedule:
a. Single-walled spill containment systems – once a year, not to exceed 12 months.
b. Piping sumps, dispenser sumps, double-walled spill containment systems - every three years, not to exceed 36 months.
c. Piping and dispenser sumps over the surface waters of the state shall be tested every three years thereafter, not to exceed 36 months.
Repairs, Operation and Maintenance
Storage tank system equipment shall be maintained in sound operational condition to reduce the likelihood of releases and incidents. Corrosion of metal components must be minimized by periodic maintenance. Water in excess of one inch in depth or any regulated substances collected in secondary containment shall be removed within 72 hours of discovery and properly disposed.

How do I document the Tank Inspections and Certification?
Upon completion of inspection, the contractor or certified operator must provide a detailed report with the following:
Detailed information on the condition of the tank, accessories, and appurtenances.
Detailed information concerning required and recommended repairs and renovations.
Drawings detailing the inspection information and color pictures illustrating the inspection findings.
Comparison and analysis of the tank’s current condition with the original tank fabrication conditions.
