1.0 INTRODUCTION <br />The purpose of this Bare Area Work Plan is to identify the bare ground work to be completed for <br />areas at the Telluride Tailing Piles 4, 5 and 6 (TT4, TT5 and TT6) and the Red Mountain Tailing <br />Piles 2 and 3 (RMT2 and RMT3) managed by Idarado Mining Company, located in San Miguel <br />and Ouray Counties, Colorado. The Revegetation Monitoring of Telluride and Red Mountain <br />Tailings Piles: Results from 2008 (MWH 2008) report indicated that the crest of RMT3 has low <br />plant cover. Additionally, the Colorado Department of Public Health and Environment (CDPHE) <br />in comments to the same report, characterized the top surface and west-facing slope of TT4 <br />and an area on the north-facing slope of TT6 as having low plant cover. Idarado Mining <br />Company has also identified the crest of RMT2 as having low plant cover. This work plan has <br />been developed to address those identified areas. <br />The work that will be performed pursuant to this work plan includes: <br />• Mapping of identified bare areas <br />• Placement of a rock armor layer on the crests of RMT2 and RMT3 <br />• Placement of a material cover over identified areas of TT4, TT5 and TT6 <br />• Revegetation of covered areas on TT4, TT5 and TT6 with the RAP seed mix or <br />alternative seed mixture developed for wetter locations <br />• Revegetation of the soil borrow area, as necessary. <br />2.0 BARE AREA DELINEATION <br />The bare areas will be staked in the field, and the perimeter mapped using Global Positioning <br />System (GPS) technology. The purpose of the field mapping is to determine the total area for <br />planning, as well as the location for future monitoring. <br />3.0 BARE AREA REMEDIATION <br />3.1 RMT2 and RMT3 <br />The bare areas on the crest of RMT2 and RMT3 will be addressed through placement of a <br />geotextile fabric, with rock armoring along the length of the crest, approximately 10 feet wide. <br />Prior to rock placement, woven geotextile fabric will be placed on the tailing surface in the area <br />where rock armoring will be placed to prevent movement of tailing into the rock material. The <br />rock armoring will be placed approximately 6 inches thick. The rock material will be sourced <br />from the Barstow borrow area. <br />July 31, 2009
