Brusca File No. 137-002 <br />Page 10 <br />December 14, 2018 <br />Murphy Parkway Property Waste Materials Management Verification Report <br /> <br /> <br /> <br />7.0 SUMMARY AND CLOSING <br /> <br />As described herein, capped waste materials were excavated and removed from the WU1 portion <br />of the subject property earlier this year in accordance with agency-approved workplan <br />documentation. Our observations, as well as laboratory testing of verification soil samples <br />beneath the removed wastes, indicate that the WU1 removal activities were successful. Based on <br />the laboratory analytical results, residual soil conditions in this area do not pose an unacceptable <br />risk, considering future commercial/industrial site usage. <br /> <br />The excavated/removed waste materials from the WU1 area were stockpiled onsite, sampled, and <br />tested for an extensive suite of chemical analyses. Based on the laboratory results, it was <br />determined that it was appropriate and acceptable to reuse the WU1 materials in cement-treated <br />subgrades for the building pad and pavements during construction at the site. Our observations <br />indicate that the waste reuse activities were performed in accord with the approved workplan <br />documentation. <br /> <br />This report will be submitted to the SJCEHD, the CVRWQCB, and CalRecycle for review and <br />approval.
