Amendments en bloc prevented federal law from preempting the ability of States to set higher standards for oil pollution liability and more complete systems of compensation than allowed under the bill or current law. They protected the rights of States to set higher levels of financial responsibility, left State court jurisdiction intact, and made State standards applicable to cleanups. \ As amended by the Davis amendment (A006), language was clarified to provide that a Federal official, rather than a State official, would be the sole authority in determining whether a cleanup had been completed.
