The major obstacle to the siting of hazardous waste facilities is local public opposition to State siting efforts. State nonnegotiative facility siting techniques include citizen participation on siting boards, local advisory committees, and through public hearings and the site designation process; and the State preemption of local authority. State negotiative siting techniques provide a role for mediation and arbitration. Massachusetts, Rhode Island, Wisconsin, and Connecticut provide for such an approach. The laws in all four States permit a judicially enforcible siting agreement between the community and developer, local representative committees that include community officials and citizens, the involvement of abutting communities and the general public in the siting process, technical assistance grants for the local committee, deadlines for negotiations, and subsequent arbitration to resolve impasses. The statutes differ regarding the community's obligation to negotiate. Although the effectiveness of these statutes in resolving siting disputes has yet to be determined, they promise a better approach than unstructured conflict or formal litigation. 332 footnotes.
