Field Sampling Plan for the Accelerated Retrieval Project I

iii The purpose of the Accelerated Retrieval Project I is to demonstrate a simplified retrieval system for removal of transuranic waste at the Subsurface Disposal Area. This field sampling plan describes how and where samples will be collected during waste retrieval operations to support determination of the (1) transuranic activity and physical description of the materials, which would have otherwise not been retrieved, that affect visual criteria for future decisions; (2) presence of radiological OU 7-13/14 contaminants of concern in material which would have otherwise not been retrieved, (3) concentration of volatile organic compounds and radiological contaminants of concern in the underburden; and (4) whether the excavated waste zone material should be regulated under the Toxic Substances Control Act. The plan also describes how samples will be collected of roaster-oxide waste to support disposition of roaster-oxide waste to Idaho National Laboratory Comprehensive Environmenta
