The rights and responsibilities of a state or tribal government at a Superfund site will vary depending on certain stipulations. As the Superfund program has evolved, state and tribal involvement has increased. Approved states and tribes are encouraged to take the leads at appropriate sites, freeing Superfund resources for use at other sites. The following links provide information about the role of state, tribal and local governments in the remedy selection process.
