Title: Assessing risks of contained-in wastes may substitute for treatment, disposal
Abstract: According to EPA's contained-in rule, soils and groundwater containing RCRA-listed hazardous waste must be managed as hazardous until they no longer contain the waste, no longer exhibit a characteristic, or are delisted. This usually is quite costly. However, for some materials, there is a less expensive alternative -- a risk-based determination that the material is non-hazardous. EPA has not issued clear guidance on how to determine that contained-in materials no longer contain listed wastes. However, the agency says it assumes contained-in materials can be treated to levels that render them non-hazardous. Despite delays in promulgation of EPA's Hazardous Waste Identification Rule, the Agency appears unlikely to provide definitive guidance on managing contained-in materials. Rather, EPA is likely to continue focusing on broader aspects of waste classification. The recent corrective action management unit (CAMU) rule facilitates managing remediation and investigating wastes at RCRA corrective action facilities, and some Superfund sites; RCRA minimum technology requirements and land disposal restrictions do not apply within CAMUs.
