Editors' Summary: The 1986 Superfund amendments have had dramatic impact on environmental law in general, and their specific application to federal facilities is no exception. In this Article, the author outlines the amendments' effects on the Department of Defense's hazardous waste cleanup program, and also analyzes the provisions common to all federal facilities. In particular, the author reviews the increasingly difficult issues involved in applying Superfund requirements as well as Resource Conservation and Recovery Act provisions at the same sites, and suggests an interpretation of the statutes that applies relevant provisions of both yet still avoids duplication and conflict.
