The RAP excavations are shown for <br /> Areas 10, 11, 15, and 20 and 21 in Figures,3,,.4;,,5.and 6,respectively. <br /> r <br /> The RDIP described project information and specific procedures to be used to implement the <br /> RAP and FS and included: <br /> I <br /> • Project organization; <br /> • Well abandonment activities; <br /> • Excavation confirmation and sampling procedures; <br /> • Quality Assurance/Quality Control (QA/QC) sampling procedures; <br /> • Sample handling aryl analysis procedures, and <br /> j • Soil handling, transportation and disposal procedures. <br /> 4.0 DEMOLITION AND WELL ABANDONMENT <br /> The planned redevelopment required that all above and below'ground improvements be <br /> demolished, and all monitoring wells be destroyed prior to grading operations for the new <br /> development. <br /> I <br /> Between December 2003 and February 2004, Evans Brothers Construction (Evans Brothers) <br /> demolished all structures at the Site. Between 1and 16 March, Spectrum Exploration, under the <br /> supervision of Treadwell & Rollo personnel, destroyed 45 groundwater monitoring, four <br /> groundwater extraction, 25 air sparge, 26 ozone, and eight vapor extraction wells (Figure 2). <br /> Table 2 summarizes the well destruction methods and activities. All monitoring wells were <br /> f destroyed in accordance with California well destruction guidelines and SJCEHD requirements. <br /> Work plans and well destruction permits were prepared for the well destructions at Areas 15, 16, <br /> 3 <br /> ' and 21 and a well destruction permit was prepared for Area 10 (Treadwell &Rollo, 2003 a,b, <br /> c, d). The work plans included commitments to install new monitoring wells at Areas 15, 16 and <br /> 25971025.DGD 9 11 August 2005 <br /> r <br />
