This federal law, also known as “Superfund,” was passed in 1980. It established a program to (1) identify sites where hazardous substances have been, or might be, released into the environment; (2) ensure that these sights are cleaned up by the responsible parties or the government; (3) evaluate damages to natural resources; and (4) create a claims procedure for parties who have cleaned up sites to recover their costs from a responsible party or parties.
