Box 466 <br />Silverton , Colorado 81433 <br />970 - 387 - 5772 -Fax 970 - 387 -5019 <br />RECEIVED <br />AU0 12 2011 <br />o visioh �m a•We wimation, <br />✓✓ Mining and Safety <br />The Eureka Gavel Pit M- 1990 -070 in San Juan County is and has been an <br />"inactive" mining gravel operation and some reclamation and safety measures <br />have been done at the pit site. The County is stockpiling gravel at the Eureka pit <br />that is being hauled in from the new private gravel operation two miles west of <br />Eureka. There has been NO mining activity at this site in 2009 and there will be <br />no mining in 2010 or in the foreseeable future. San Juan County needs to get <br />released from liability and drop the permit in 2011 -2012. <br />There has been some minor sloughing on the slope above the pit and that was <br />caused by the winter avalanche and spring snow melt and also from the dumping <br />of materials off of county road #25. Ther was a small mudslide on CR -25 this <br />summer but did not affect the road or slope. <br />San Juan County has meet most requirements set forth by the board and <br />recommendations by the Minerals and Geology inspector. The County has done <br />the following steps to meet the MLRB requirements since 2004. <br />1. A catchment trench and berm was dug and constructed at the base of the <br />excavated slope in September of 2005. <br />Louis Girodo <br />San Juan County Road Overseer <br />
