The plan called for the implementation of monthly monitoring for PCB of 5-shaft <br /> water for a 12 month period,and quarterly monitoring of the Arkansas Monitoring Well for PCB for a <br /> period of six calendar quarters. Results of these analyses were to be submitted during the agreed upon <br /> month of September of 2001. The first of the quarterly samples taken from the Arkansas Monitoring Well <br /> was taken in the third quarter of 2000. Because the submittal is due before the sixth quarter of testing, <br /> Climax is submitting the results of six sample events from the previous consecutive five quarters ending <br /> with the third quarter of 2001. The PCB analyses for the fourth quarter of 2001 will be submitted within 30 <br /> days of our receipt of these results. <br /> The results of the corrective plan show that no PCB's have been detected during the sampling period at <br /> either 5-shaft or the Arkansas Monitoring Well. As a result of these analyses,Climax will discontinue the <br /> PCB Monitoring Plan in the fourth quarter of 2001. This will be contingent upon the last sample from the <br /> Arkansas Monitoring Well showing non-detect for PCB,s. <br /> If you would like to further discuss these matters,I can be reached at(719)486-2150 Ext. 755. Please feel <br /> free to call me at your convenience. <br /> Sincerely, <br /> Lisa Berry <br /> Environmental TeLician <br /> Climax Mine ()L)A1.�. y <br />
