What each one is
Gasoline
the commonest substance in the register and the reason most of these facilities exist — filling stations. Petrol tanks are the ones the federal upgrade rules were written for.
Diesel
found at filling stations, but also at depots, garages and any site that fuels its own vehicles.
Heating Oil(on-site Consumption)
heating oil kept for the building it stands under — schools, churches, apartment blocks, offices. These are not commercial fuel sites, and they are the part of the register the public least expects to find.
Not stated
the file records no substance for these tanks.
Used Oil
waste oil held for collection, typically at garages.
Hazardous Substance
a category the state uses for tanks holding regulated substances other than fuel. The file does not say which substance.
