RCRA Online Number:14174
To:Regions 1-10
Organization of Recipient:EPA
Description: Provides guidance on risk-based clean closure. RCRA regulated units may be clean closed to protective risk-based media cleanup levels. EPA interprets the "remove or decontaminate" clean closure standard to mean that all hazardous waste and liners must be completely removed, but that some limited amount of hazardous constituents may remain on environmental media provided risk-based cleanup levels are met (SEE ALSO: 52 FR 8704; 3/19/87). The use of fate and transport models is appropriate for modeling the potential for residual contamination to migrate from one medium to another. Cleanup levels for environmental media may take into account non-residential exposure assumptions and future land use, provided that those assumptions are clearly stated and that any land use restrictions are maintained.
