Petroleum bulk storage

Petroleum bulk storage is the regulatory category for fuel tanks above the registration thresholds: covered tanks register with the state, carrying records of location, capacity, construction, and status — active, closed, removed. Heating-oil tanks under old buildings and service-station tanks under corner lots are the city's typical cases, and the registry is where their existence becomes public fact.

Tanks matter because they leak, historically often: an aging or improperly closed tank is a standing contamination question, and 'closed in place' is a records answer that still leaves steel in the ground. In diligence, tank records pair with spill files — a registered tank plus an open spill number is a documented problem; a former fuel use with no tank record at all is a question mark that predates the registry.
