Should all 'environmental hazards' be kept?

There was a mass import of ‘environmental hazards’ from the US EPA database. There are some strange ones, like “NYCHA QUEENSBRIDGE SOUTH HOUSES”, a housing project (presumably there are issues with waste disposal or something), but these could be useful if cleaned up. But then there are ones like “NYCT-ASTORIA LINE BENTS 114-135”, literally a segment of an elevated subway line. Is there any reason not to remove this point?

If a node clearly doesn’t make sense, it is good to remove it. The one who uploaded them is open to ideas on how to improve the import.
