Mr. Bob Oswald, Recla~tion Specialist • <br />October 25, 2001 <br />Page 2 of 2 <br />Monitoring as per the requirements of the Technical Revisions is now completed <br />upon submittal of this September 2001 Monthly Monitoring Report. During the two <br />year period following injection of tracer behind the 9360 adit plug, no tracer has <br />been detected at any of the monitoring points. In addition, visual inspection of the <br />plug and surrounding area indicates no seeps have developed. Therefore, we <br />conclude that the 9360 adit plug is highly effective in preventing any discharge from <br />the adit and is performing as expected. <br />Homestake will be contacting the DMG in the near future regarding the final <br />decommissioning and closure of the 9360 adit plug and portal. Associated <br />construction and closure activities will commence as soon as feasible, with a <br />preference being given for completion this fall as weather allows. <br />Thank you for your time and attention on this matter. If you have any questions, <br />please contact me at (505) 287-4456 in our Grants, New Mexico Office. <br />Si rely, <br />cc: A. Cox, HMC Walnut Creek <br />R. Burgess, Del Norte FS <br />D.
