The Division conducted a monitoring and construction progress inspection of the site on December 29, 2011. Mr. Mark <br />Vanoni (CC &V Sr. Environmental Coordinator) was present during the inspection. <br />Inspection: <br />Mr. Vanoni showed how the breached Phase IV berm repair had been completed. AMEC is expected to submit <br />a construction QA/QC report for the berm repair. <br />AMEC has begun stripping the topsoil in the area for the new mill (see Photos 1 and 2). <br />The inspection continued as the Division visited each of the high and low solution collection system transducers <br />and recorded water level values. The recording sheet is included as Attachment A, and the values are <br />summarized below in the Transducer Readings. The Division noted the 80% capacity level for the Phase V <br />High Volume Solution Collection system was not posted near the caissons or transducer readouts. Mr. Vanoni <br />indicated a sign had been made and he would ensure it is posted prior to next month's inspection. <br />CC &V has finished drilling the new monitoring well (see Photo 3). In addition to the water being found as <br />expected in the upper 20 feet of the well, a water - bearing "sandy" zone was encountered at approximately 97 to <br />100 feet below ground level. A well construction/completion report is expected soon. CC &V has also nearly <br />finished the pumpback system for Well CRMW -A and CRMW -B (see Photos 4 and 5). The crew was there <br />and provided a demonstration that the system is functional. CC &V still needs to establish water levels at which <br />the pumps will be activated such that pump reliability are optimized. <br />The Arequa Gulch underdrains were inspected. The South Underdrain discharge was measured by Mr. Vanoni <br />to be 3 gpm. Both the North Underdrain and the AG /Spring were dry. No flow was observed in the Arequa <br />Gulch flume (see Photo 6). <br />Transducer Readings: <br />Phase I High Volume Solution Collection (readings in ft) <br />Pump #299 / XDCR #xx Pump #300 / XDCR #00 <br />41.4 37.0 <br />Pump #301 / XDCR #01 Pump #302 / XDCR #02 Pump #303 / XDCR #03 <br />26.5 29.1 29.0 <br />Phase I Low Volume Solution Collection (readings in ft) <br />Pond Lvl / XDCR #1 System Press / XDCR #2 <br />43.50 44.50 <br />Phase I Pond Piezometers (readings in ft) <br />Piezo #1 (HAND) <br />0.26 <br />Piezo #2 (AUTO) <br />0.48 <br />OBSERVATIONS <br />Phase II & III High Volume Solution Collection (readings in ft) <br />Pump / XDCR #4 Pump / XDCR #5 Pump / XDCR #6 <br />19.8 21 20 <br />PERMIT #: M -1980 -244 <br />INSPECTOR'S INITIALS: TC1 <br />INSPECTION DATE: December 29, 2011 <br />Page 2 of 7 <br />
