Guidance: De Minimis Waste Contributor Settlement Methodologies

This guidance is designed to provide practical assistance in the evaluation and development of de minimis contributor settlement proposals and agreements. The Superfund Amendments and Reauthorization Act of 1986 (SARA) codified the concept of de minimis settlements, which was originally 
introduced in the "Interim CERCLA Settlement Policy" (December, 1984). The focus of this guidance is solely on de minimis contributor settlements. OSWER Directive No. 9834.7-1B. Issued 12/20/1989.
