Editors' Summary: The first Ruckelshaus EPA Superfund settlement was concluded recently between the federal government and a group of companies that generated hazardous wastes found at the Environmental Conservation and Chemical Co. (Enviro-Chem) disposal site in Zionsville, Indiana. Mr. Bernstein, cochairman of the generators' steering committee in the negotiations, describes how the parties resolved the critical issues of allocating liability among the generators and establishing a practical mechanism for operating the cleanup trust fund that will pay for cleaning up the site. In addition, he outlines the complaints that the generators have filed against the owners and operators of the site and their insurance carriers, the first suit for reimbursement among Superfund parties.
