Owners and operators of petroleum underground storage tanks (USTs) must prove they can cover the cost of corrective action and third-party damage from a release, in specific dollar amounts set by federal regulation and, in some states, by an alternative state-run mechanism. 40 CFR 280.93 sets the federal baseline: $1 million per occurrence for petroleum marketers, $500,000 for other owners, scaling to $2 million annual aggregate for owners of more than 100 tanks. States can adopt these amounts directly (Florida's own DEP quick-guide reproduces the identical figures) or substitute their own compliance route (California lets an owner use the state UST Cleanup Fund as the mechanism, which caps what the Fund pays and leaves a much smaller amount to be carried privately, sized by the claimant's priority class). Each record is one coverage tier: the dollar amount, whether it is a per-occurrence limit, an annual aggregate or a deductible, who it applies to, and the source section, quoted verbatim. Answers 'how much UST insurance coverage do I need', 'what financial responsibility amount applies to my tanks', 'does my state require more than the federal minimum'.

## Provenance — what every record carries

Every record carries `source` (the URL the value was read from) and
`source_quote` (a verbatim quote from that page stating it). A value you
cannot check against its page is indistinguishable from an invented one;
these can all be checked. Each record is also individually addressable on
the canonical site at its `url`.

## Licence position

Federal regulatory text (40 CFR) is a US government work, not copyrightable; state agency guidance documents cited for their facts, not reproduced in full

Facts are not copyrightable; what this dataset takes from each source is a
fact plus a short attributed quote linking back to the page that states it.
