Spill record

A spill record is the state's file on a reported petroleum or chemical release: reports are mandatory on discovery, each event receives a number, and the file tracks the release from report through investigation to closure — or through years of remaining open. Location, substance, quantity where known, and status make the records screenable at address and area level.

Reading spills honestly means reading status and vintage: a closed decades-old heating-oil spill is common urban history; an open spill at or beside a lot is an unresolved condition with someone's name on it. Clusters tell area stories — the gas-station corner, the industrial block — and absence, as always, means no report, not no release.
