Brusca File No. 137-002 <br />Page 9 <br />May 23, 2018 <br />Murphy Parkway Property Waste Materials Reuse Workplan <br /> <br />concrete paved. It is estimated that approximately 500 cubic yards of waste materials will be <br />excavated from the building pad following construction and cement treatment of the building <br />pad. These materials will be placed within the upper one foot of the concrete pavement <br />subgrades (see Plate 5) and will subsequently be cement treated. The project Foundation <br />Investigation indicates that the pavement subgrades will be cement treated in a similar manner as <br />described above for the building pad subgrade. <br /> <br />This Workplan does not address physical hazards (such as those posed by the waste glass within <br />the materials removed from WU1 on the property); protection against physical and construction <br />hazards are the responsibility of future contractors/workers and other site personnel and are not <br />included in the scope of this plan. It is recommended that all agencies, companies, and workers <br />whose activities may result in exposure to the materials removed from WU1 (including waste <br />glass materials and dust) develop health and safety plans specific to the site conditions and their <br />activities, and that such measures consider/address potential inhalation hazards posed by glass <br />dust, as well as cut/abrasion hazards posed by glass fragments. <br /> <br />6.3 Verification Observation and Reporting <br /> <br />A qualified environmental professional will make observations of site activities that involve the <br />onsite transport, placement, and cement treatment of materials removed from WU1 to confirm <br />that the procedures described herein are implemented. Additionally, earthwork quality control <br />observations and testing will be performed by the project geotechnical engineering firm. The <br />locations of placement of the materials removed from WU1 will be recorded on a scaled site <br />plan. Upon completion, a report will be prepared summarizing the materials reuse activities <br /> <br /> <br />7.0 CLOSING <br /> <br />This Workplan will be submitted to the SJCEHD, the CVRWQCB, and CalRecycle for final <br />review and approval prior to finalizing the Wor kplan and implementing the onsite reuse of the <br />materials removed from WU1.
