v. 1. Development of an RFI work plan and general considerations for RCRA facility investigations.--v. 2. Soil, ground water and subsurface releases.--v. 3. Air and surface water releases.--v. 4. Case study examples. On November 8, 1984, Congress enacted the Hazardous and Solid Waste Amendments (HSWA) to RCRA. Among the most significant provisions of HSWA are 3004(u), which requires corrective action for releases of hazardous waste or constituents from solid waste management units at hazardous waste treatment storage and disposal facilities seeking final RCRA permits; and 3004(v), which compels corrective action for releases that have migrated beyond the facility property boundary. EPA will be promulgating rules to implement the corrective action provisions of HSWA, including requirements for release investigations and corrective measures. This document, which is presented in four volumes, provides guidance to the owner or operator of hazardous waste management facilities as to the conduct of the second phase of the RCRA Corrective Action Program, the RCRA Facility Investigation (RFI). Instruction is provided for the development and performance of an investigation based on determinations made by the regulatory agency as expressed in the schedule of a permit or in an enforcement order issued under HSWA3008(h). The purpose of the RFI is to obtain information to fully characterize the nature and extent of releases of hazardous waste or constituents. This information will b used to determine whether interim corrective measures or a Corrective Measures Study will be necessary.
