Comment/Objection Narrative* <br />Over the past several decades, countless hours of work and millions of dollars have been spent on repairing the <br />devastating impacts of historic mining in Lake County on the Upper Arkansas River and its tributaries, <br />particularly in the California Gulch watershed where the Leadville Mill and much of the targeted waste is <br />located. As a result, the Upper Arkansas is now the longest continuous stretch of Gold Medal water in the <br />nation. <br />I would ask DRMS to consider if the risks of this project to the Leadville community and the surrounding <br />environment are worth the benefits. Of particular note, we would ask DRMS to carefully consider the following: <br />Does the CJK proposal adequately identify groundwater depth throughout the site or the preferential flow <br />pathways/rates? In the instance of a spill, it would be necessary to have groundwater defined. Groundwater <br />mapping would also play into a remediation plan in the instance of a spill. Those pathways must be identified <br />and mitigated during an emergency to reduce impacts on drinking water supplies including wells in the area. <br />Has CJK properly addressed concerns around the daily operations of the mill, such as mitigating impacts to <br />wildlife and exposure to materials with elevated sodium -cyanide? This can include both terrestrial and aquatic <br />wildlife/organisms. <br />Has CJK properly addressed the disposal of processed waste throughout the life of the mine? Where will <br />processed waste be disposed of or remediated to reduce impacts on human health and the environment? Does <br />the life cycle of the proposed disposal plan fully mitigate the risks of its location in a highly sensitive <br />environment? <br />Does the CJK proposal address the risks to the community and the environment of disturbing the east side <br />waste piles? The potential for release of toxic materials into the air, surface water, and groundwater must be <br />addressed both during and after excavation. These waste piles have stabilized over time and disturbing them <br />will increase the potential for erosion of freshly exposed surfaces by wind and water. <br />Permit Number* <br />Enter valid letter and then numbers, for example M1977999, M1999777UG or C1981201. <br />M1990057 <br />Permitting Action Type <br />Select revision type or leave blank if comment pertains to a new permit application or NOI <br />Permit Type <br />County <br />Lake <br />Enter one county only <br />Site Name <br />Perm ittee/ Operator Name <br />ADDITIONAL INFORMATION <br />Are there supporting photos, maps, or documents you wish to upload? * <br />
