Preliminary assessments were prepared for 29 previously identified Sites, and Potential Release Locations PRLs in Operable Unit OU B at McClellan AFB. Preliminary assessments for 33 Study Areas SAs were also conducted to determine if areas other than Sites and PRLs in OU B require further investigation. Further investigation of a number of PRLs and SAs is considered necessary only because the potential exists for contaminant release. Each Site, PRL, and Study Area was evaluated according to whether or not the area has confirmed soil contamination, documented contaminant releases, a history of hazardous material use, or other evidence of contaminant release. After applying those criteria, the following recommendations are made All six Sites 23, 30, 31, 36, 47, and 48 in OU B should be further investigated to fully characterize the nature and extent of soil contamination Eighteen of the previously identified PRLs should be investigated further for soil contamination Five previously identified PRLs require no further action and are recommended for removal from the list of Potential Release Locations Nineteen Study Areas identified in the assessment of OU B should be investigated further Fourteen Study Areas identified in the assessment of OU B require no further action and Data collected during this investigation should be used in the sampling and analysis plan for the contaminant source investigation for OU B.
