10 Boeing SB 990 Technical Memorandum September 2008 This technical memorandum presents an analysis of two SB990 implementation alternatives (Default and SSFL site-specific) and compares the resultant estimated remedial volumes associated with each of these alternatives to a current planning estimate (Base Case) developed using DTSC-approved risk assessment methodologies for the site. (2007 Agreements, agreed to be protective according to DTSC testimony.) 10

21 Conclusions 2010 AOC cleanup requires from 3 to 5 times as much soil removal and areal disturbance as a risk-based cleanup. As cleanup requirements become more severe environmental consequences become greater. It is proper to ask what benefits accrue to the community from the additional remediation, both onsite and off-site. We must be vigilant when reviewing the DOE EIS and DTSC EIR to ensure that these questions are answered fully, before cleanup decisions are made. 21
