Understanding the RCRA corrective action process

Abstract The Resource Conservation and Recovery Act (RCRA) was enacted in 1976. The Hazardous and Solid Waste Amendments (HSWA) of 1984 specify “corrective action” requirements for protecting human health and the environment from environmental contamination at active hazardous waste treatment, storage, and disposal facilities. RCRA and its corrective action requirements are designed to prevent the creation of new Superfund sites by regulating and remediating active facilities. The RCRA corrective action process has four basic components: the facility assessment, facility investigation, corrective measures study, and corrective measures implementation. This article presents an overview of the RCRA corrective action process and presents four case studies from three U.S. EPA regions.
