' 0 0 <br /> ' The proposed sampling plan may be constrained or modified due to a variety of factors at <br /> the Site (i.e. property owners consent, current structures on the Site,dogs,resident <br /> ' availability,fences,location accessibility). At the time of the workplan writing, Site <br /> Access Agreements have been obtained from 16 of the 20 property owners at the Site. <br /> ' When the other properties become accessible,samples will be collected as proposed in <br /> this report. All modifications and variations of the sampling plans will be documented in <br /> the PEA Report. If significant modifications to the sampling plan are required,DTSC <br /> will be notified prior to the commencement of sampling. <br /> Due to the large volume of samples and accessibility issues stated above,only surface <br /> ' samples may be collected at this time. After the surface samples are collected, a wooden <br /> stake and flagging will be placed in the sample hole and the bearings and distance will be <br /> measured from appropriate permanent structures at the Site. Pending the results of the <br /> ' surface samples,deeper and step-out samples will be collected and analyzed if necessary. <br /> 6.2 Proposed Sampling and Analytical Testing Plans <br /> ' A summary table of all parcels on the Site and corresponding sample analysis is located <br /> in Tables 5 and 6 below. In addition,Figures 9-28 show a parcel by parcel sampling <br /> plan.
