were established to correspond to a 1 in 10,000 increased lifetime risk of cancer. As a matter of comparison, for a Superfund site cleanup the desired cleanup goal is a 1 in 1,000,000 increased lifetime risk of cancer with a minimum goal of 1 in 10,000.

14. Section clarified by adding the following statement:
