Florida underground storage tanks: 4 in 10 inspected facilities out of compliance
Florida's Department of Environmental Protection inspected 3,573 underground storage tank facilities in the year ending September 30, 2025 and found 60.66% in significant compliance with Chapter 62-761 of the Florida Administrative Code. The rest, roughly four in ten, were not. A hotel or condominium with an underground generator fuel tank is one of the 9,384 facilities in this program.

| Underground storage tanks | 21,475 |
| Facilities inspected | 3,573 |
| Significant compliance rate | 60.66%, defined as the percent of facilities in technical compliance with Chapter 62-761, F.A.C. |
| Releases reported | 118, of which 25 were later found not to be from an underground tank |
| Confirmed releases | 93 |
What this means for a hotel or a condominium
Chapter 62-761 applies to underground tanks above 110 gallons that hold regulated substances, and a diesel tank feeding an emergency generator is the usual way a building ends up in it. Technical compliance is the paperwork and the hardware together: registration, release detection records every month, the annual test of the detection devices, containment integrity, financial responsibility and a trained operator. A 60.66% rate means the inspector who arrives expects to find something, and the common findings are the monthly records that were not kept rather than a leaking tank. Aboveground tanks over 550 gallons fall under the companion rule, Chapter 62-762, with the same registration and inspection pattern.

What is not on this page, and why
DEP's summary does not separate release-detection from release-prevention compliance, does not list enforcement actions, and does not break the figures down by county or facility type. Aboveground tank statistics are not in this document. Confirm your tank's status with the county's tank inspection program (DEP contracts most inspections to counties) and your registered tank contractor.
