The <br />material was placed in the PSSA using a Cat dozer. <br />Subgrade: Phase 1 and 2 rough subgrade preparation occurred. No additional subgrade was <br />approved during this reporting period. <br />Soil Liner Fill (SLF): (Placement Operations Temporarily Suspended) <br />Cameron Site: SLF processing continued at the Cameron Site. <br />Underdrain System: <br />Primary Underdrain: Complete. <br />Secondary Underdrain: No work was performed during this reporting period. <br />Tertiary Underdrain: No work was performed during this reporting period. <br />Leak Detection: No work was performed during this reporting period. <br />B) Underground Workings: <br />Underground working numbers #6362, #6364, #6591, #6592, #6595, #6596, #6599, #6620, and <br />#6654 were excavated to competent rock, backfilled per project specifications, and are <br />considered remediated. <br />Confirmatory drilling and blasting occurred at working #6010. Additional remediation is required. <br />On January 15, underground workings #6590, #6593, and #6594 (all shafts) were excavated to <br />approximately 25 feet. The bottoms were not encountered. Drill access will be provided. Further <br />remediation is required. <br />C) Geomembrane: <br />Phase 1 80 -mil DSMS LLDPE Liner Installation: (Installation is suspended at this time.) <br />D) Drain Cover Fill (DCF) (Placement operations suspended at this time.) <br />E) High Volume Solution Collection System Piping (HVSCS): <br />No work was performed during this reporting period. <br />II) Storm Water Management <br />Best Management Practices (BMPs) are being performed. <br />201 M1 -17 -mW weekly f nal.docx Page 2 of 6 <br />
