The plastic pipe casing is squeezed at the 20 foot level making it difficult to lower a bailer. <br />Using a smaller diameter bailer we have found very minimal water available in the well. In fact <br />there are times when the initial bailing of the well to remove one volume effectively drains the <br />available water. The lack of water in the well and the poor water quality suggests there is little <br />transmissivity and connection between the North Fork of the Gunnison River and the B seam <br />coal at this particular vicinity of the mine. The elevated 2012 levels of zinc and iron appeared to <br />return to "normal" but sulfate seemed to remain elevated. Perhaps the lack of water in the well is <br />skewing the results. Overall depth appears to be "normal". The well was again dry in 2018. <br />As the locations of SC -1 and SC -3 wells serve to monitor only the Rollins sandstone and B -seam <br />coal respectively up- rag_ dient of the Sanborn creek mining area, their utility towards the <br />monitoring of the Sanborn Creek mine itself remains somewhat limited. <br />6.0 Mine Water Information <br />Elk Creek Mine Water <br />The water utilized at the mine property continues to be all imported from the alluvial water <br />supply well located near the North Fork of the Gunnison River per the OMLLC water rights and <br />Augmentation Plan. <br />During 2012, the 4 West and 5 West seals flowed at a combined rate of 12.3 gpm The 13 west <br />entry 1 seal flowed —80 gpm. The 4B entry 10.5 crosscut flowed 2.69 gpm. The 4N entry, 3 E <br />crosscut flowed 23.08 gpm. <br />During 2013, the mine was sealed or idled for most of the year. An assessment of mine inflows <br />was not possible during 2013 but it is likely similar to 2012. During 2014 the mine remained idle <br />and at the end of 2015 the mine was permanently sealed. <br />See the D213 and D2132 well discussion above for information regarding the transfer of collected <br />Elk Creek mine sump water to the abandoned Somerset B/C seam workings. <br />Water is no longer removed from the mine workings. <br />Outfall 011 — Sanborn Creek Mine Water Discharge <br />Outfall 011 was the OMLLC - CDPS mine water discharge point from Sanborn Creek Mine that <br />discharged into Sanborn Creek <br />The Sanborn Creek Mine water drainage system was decommissioned on May 21, 2003. Since <br />the mine completed the last panel, the underground hardware was removed and the entries were <br />seated in accordance with MSI3A requirements. <br />During 2004, CDMG approved PAP TR -45 which removed Outfall 011 as a monitoring point. <br />19 <br />
