Well on paper the petroleum company (Generator) is still liable for the cleanup as well as anyone who gave waste to the hauler.
It is called cradle to grave tracking mentioned in a bit of light reading called 49CFR.
It happens from one end of the country to the other.
If the price for waste disposal is too low there is probably a reason.
Do a search on a place called Western Environmental. They thought they would be exempt from Federal laws by placing their waste treament facility on
soverign indian land. Unfortunately you are an indian (without a SSN) you are not immune from their web of rules and regulations.
However many of the Calif Gov sites sent their waste to Western and it will be interesting how they spin the laws to the privately owned facilities
are required to pay for the governments portion of the cleanup. Another classic case of I make laws for 'you' to follow but I am exempt from them.
