�-r,L�Z g Y?,COLORADO LEGACY LAND <br /> • On page 2, the sentence "The operation intercepts 'clean' surface flows and alluvial..." should be <br /> revised to more accurately read, "The operation intercepts upgradient surface flows and alluvial...". <br /> This text more accurately reflects the presence of natural uranium in the Ralston Creek watershed and <br /> provides a more technical description of the water source. <br /> • On page 2,the sentence"The dedicated winch system will be installed adjacent to the Jeffery Air Shaft <br /> on a concrete footer"should be revised to read,"The dedicated winch system is adjacent to the Jeffery <br /> Air Shaft on a concrete footer". <br /> • On page 3,the sentence"The red-colored water was flowing at an estimated rate of 1-2 gpm..."should <br /> be revised to more accurately read,"No estimation instruments or measurements were used during <br /> the time of the inspection. However, the red-colored water was observed to be a slow trickle. <br /> Additionally,red-staining is observed by the operator Alexco in the Ralston Creek drainage,including <br /> upgradient of the property". <br /> • One page 3,the sentence"The Division believe the ponded water may be impacted due to it's coloration <br /> and algae growth"should be deleted. Green algae is not indicative of dissolved uranium in water and <br /> is observed (by the operator Alexco) in Ralston Creek and pools upgradient of the property. The <br /> presence of green algae is more indicative of anoxic aquatic conditions,small scale eutrophication,or <br /> nutrient-rich water. <br /> • On page 3,the text"The operator acknowledged that,while water has never been observed seeping <br /> from the NWRP,iron staining has been observed on the side of the pile indicating that seeps do occur" <br /> should be revised to read,"The operator acknowledged that water has never been observed seeping <br /> from the NWRP". Operators have not observed any iron staining on the NWRP, this text should be <br /> removed. <br /> • One page 3, the text "This seep was described as flowing at an estimated rate of 2 gpm" should be <br /> removed as no estimation instruments or measurements were used during the time of the inspection. <br /> If you have any questions regarding this response,please don't hesitate to contact me.
