The Division conducted a monitoring and construction progress inspection of the site on January 27, 2012. Mr. Timm <br />Comer (CC &V Environmental Resources Manager) presented an overview of the status of MLE2 /AM -10. Mr. Mark <br />Vanoni (CC &V Sr. Environmental Coordinator) was present during the inspection. <br />Inspection: <br />Mr. Vanoni showed how the area near the LOB on the Phase IV pad had been regraded to improve stormwater <br />control (see Photos 1 and 2). A sign has been placed in the intersection to help prevent future grading activities <br />from interfering with stormwater (see Photo 3). <br />The contractor is continuing to strip the topsoil in the area for the new mill (see Photo 4). <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 absence of the 80% capacity level for the Phase V High <br />Volume Solution Collection system noted December 29, 2011 has been resolved. A sign has been posted on the <br />SE side of the XDCR #314 identifying 36.5 ft as the 80% capacity. <br />The recently drilled monitoring well (CRMW -3C) is not yet developed. Mr. Comer stated several volumes <br />have but pumped out, but there is still drill mud /fines in the water. This is due to the low flow /recharge rate. <br />The Arequa Gulch underdrains were inspected. The South Underdrain discharge was measured by Mr. Vanoni <br />to be 2 gpm. Both the North Underdrain and the AG /Spring were dry. No flow was observed in the Arequa <br />Gulch flume (AG 1.5- OO1A). <br />Transducer Readings: <br />Phase I High Volume Solution Collection (readings in ft) <br />Pump #299 / XDCR #xx Pump #300 / XDCR #00 <br />pulling pump 35.8 <br />Pump #301 / XDCR #01 Pump #302 / XDCR #02 <br />21.7 26.8 <br />Phase I Low Volume Solution Collection (readings in ft) <br />Pond Lvl / XDCR #1 <br />41.40 <br />Phase I Pond Piezometers (readings in ft) <br />Piezo #1 (HAND) <br />0.39 <br />Phase II & III High Volume Solution Collection (readings in ft) <br />Pump / XDCR #4 <br />24.0 <br />System Press / XDCR #2 <br />44.60 <br />Piezo #2 (AUTO) <br />0.50 <br />Pump / XDCR #5 <br />25.8 <br />OBSERVATIONS <br />Pump #303 / XDCR <br />#03 <br />26.4 <br />Pump / XDCR #6 <br />27.2 <br />PERMIT #: M- 1980 -244 <br />INSPECTOR'S INITIALS: TC1 <br />INSPECTION DATE: January 27, 2012 <br />Page 2 of 6 <br />
