The elevation of the freeboard was raised thus increasing the capacity <br />of the lower seep pond, and pumps at the pump station were overhauled at that time. <br />During the summer of 2001 both of the upper ponds were cleaned of sediment and a <br />culvert was replaced between them. There are currently no further modifications <br />planned. <br />If you have any questions or would like to further discuss these modifications please call <br />me at (719) 486 -2150 Ext. 755. <br />Sincerely, <br />Lisa Berry <br />Environmental Technician <br />Climax Mine <br />• <br />
