Pitch Reclamation Project <br />Colorado Mined Land <br />Reclamation Board <br />2008 Annual <br />Reclamation Report <br />4.6 Water Quality Monitoring <br />As outlined in TR4, Homestake has monitored water quality since 1994 to verify the <br />intended effectiveness of installation of the Pinnacle Adit plug. Water quality <br />monitoring was conducted in 2008 including sampling points located at the North Pit <br />Lake discharge (Sample Point NPL), the Tie Camp Creek drainage (Sample Points <br />TCCDRN and TCC), the site discharge POC (Sample Point SW-33), as well as spring <br />and seep surveys performed in the spring and fall. Monthly discharge-monitoring <br />reports (DMRs), pursuant to Colorado Discharge Permit System (CDPS) number CO- <br />0022756, were submitted to the Colorado Department of Public Health and <br />Environment (CDPHE) for 2008. Monitoring for the CDPS was conducted at the <br />designated POC SW-33, shown on Figure 3. Analytical tests conducted for the DMRs <br />at SW-33 as required by the CDPS include: flow, dissolved radium 226, total radium <br />226/228, total uranium, pH, total suspended solids (TSS), total dissolved solids, oil and <br />grease (visual only), potentially dissolved zinc, and whole effluent toxicity (WET). <br />During 2008, all analytical results were below the CDPS permit's 30-day average or <br />daily maximum limitations and WET testing results were within permit limits. The 2008 <br />DMRs are on file with the CDPHE-Water Quality Control Division. <br />4.7 Radioactive Materials License <br />The RTP building, foundation and sediments excavated from the upper portion of <br />Indian Creek below the old RTP area were placed in the Tie Camp Disposal Cell in <br />2001. Final grading and revegetation of the RTP area was started in 2002 and <br />completed in 2003. With the removal of the RTP, the radioactive source material and <br />any treatment capacity have been removed. Small concentrations of the Radium 226 <br />isotope remain in the sediment deposited upstream of the sediment control <br />embankment. The Radioactive Materials License (RML) for the Pitch Project was <br />renewed in April 2008. The renewal allows Homestake to manage the Tie Camp Low - <br />Grade Stockpile and the sediment upstream of the sediment control embankment <br />within the guidelines of the license. A copy of the 2008 Annual RML letter report is <br />provided in electronic Adobe Acrobat© Portable Document Format on the CD attached <br />to this report. <br />• <br />12 <br />
