Groundwater in this ephemeral drainage appears closely linked to the variable surface water flow <br />found nearby in Bear Creek. Soon after Bear Creek goes dry, typically, so drops the water level <br />in the BC -1 well. During late 2006 the monitor well was damaged by a hunter's vehicle. No <br />water samples could be taken during 2007 because of the damage. MR -85 addressed the re -drill <br />of the monitor well which was completed on November 9, 2007. On June 18, 2008 and during <br />the sampling event of August 8, 2008 attempts were made for the routine sample of the "new" <br />well. We found that the well was "pushed over" making it un- useable once again. Repairs were <br />made to the well on August 25, 2008 and the well successfully sampled on August 26, 2008. A <br />large concrete barrier has been placed in front of BC -1 to prevent additional damage. <br />During 2012 Bear Creek exhibited earlier than normal spring snow melt flows followed by the <br />usual complete absence of flow during the dry season. <br />During 2012, water samples were available in BC -1. Water Analysis of the BC -1 data suggests <br />no anomalies. <br />EC -14, EC -15 Wells - Elk Creek — Alluvium /Colluvium <br />The EC -14 well is located up gradient of the EC -15 well. The EC -14 well is located in <br />undisturbed alluvium/colluvium up- gradient from the Elk Creek mine surface facility but down - <br />gradient from the eventual D seam mining area located in the upper reaches of Elk Creek. The <br />EC -15 well is located in alluvium /colluvium located south of the D seam portal area but north of <br />the coal stockpile area. Changes in the hydrologic condition of shallow Elk Creek alluvial <br />groundwater due to mining activities could potentially be monitored from these two wells. <br />During 2011, water levels in the wells were variable. The EC -14 monitor well was proposed to <br />be moved upstream to accommodate the 2012 construction of a methane fueled, electricity <br />generation facility. In 2012 the monitor well was redrilled so as to be located off of the methane <br />facility. The old well was sealed and abandoned. <br />EC -14 showed and elevated level of chloride for no apparent reason. Overall, analysis of the <br />limited data for these wells suggest no anomalies. <br />D2B and D2B2 Mine Water Transfer Wells ( "D seam to B seam ") <br />The purpose of these two boreholes are to transfer mine water from the D seam Elk Creek mine <br />workings to the underlying Somerset B/C seam workings. The depth to water is to be measured <br />at the same frequency as the overall OMLLC groundwater monitoring program. Data is also to <br />be collected regarding 1) annual total volume of water transferred, 2) representative pH of <br />transferred water and 3) representative TSS of transferred water. <br />D2B <br />The D2B mine water transfer well was drilled and completed in late December 2004 in the <br />vicinity of the upper Elk Creek facilities area. When the drill penetrated the B Seam workings, it <br />was apparent that this portion of the B seam mine was flooded with water. The B seam was <br />encountered at the 5918' elevation and a static water level later appeared at the 6042' elevation. <br />Water transfer operations first commenced in early 2005 in D2B. During late 2011, the D2B <br />13 <br />
