Creek to the Times Mine. The pipeline from these initial pumping operations is still in place and <br /> will be removed when the new pipeline is installed." <br /> All of the other portions of the Amendment Application refer to the two (2) inch HDPE pipeline <br /> that will replace the three (3) inch and two (2) inch pipeline installed by the then permitted <br /> operators as described in the above quoted portion of the Amendment Application. <br /> 7) The operator's response to item no. 20 states the pump house (a 10 foot x 8 foot metal connex <br /> container) and the metal fuel container will be located well above the Left Hand Creek <br /> floodplain, including outside of the area affected by the 2013 flood. Please provide a map of the <br /> proposed permit area near the creek which includes the location of the 100-year floodplain of <br /> Left Hand Creek with respect to the location of all proposed structures in this area. <br /> CMC Response: The Pumphouse and the metal fuel container with its containment sump will be <br /> located well above the Left Hand Creek floodplain and floodway, in order to follow the <br /> floodplain management criteria of Boulder County and the State of Colorado. A map of the <br /> proposed permit area near Left Hand Creek which includes the location of the 100-year and 500- <br /> year floodplains with respect to the location of all proposed structures in this area is attached to <br /> this Second Response Letter. <br /> 8) The operator's response to item no. 20 states the footbridge will be situated well above the <br /> highest observed level of Left Hand Creek at this location during the 2013 flood. Firstly, please <br /> provide the base flood elevation for the section of the creek where the footbridge would be <br /> installed, and the anticipated minimum distance above this elevation at which the footbridge <br /> would be installed. Secondly, please provide design specifications for the proposed footbridge. <br /> Lastly, please state whether a permit will be required for construction of the footbridge (i.e., <br /> county bridge construction permit). If so,please commit to providing a copy of any approvals to <br /> the Division prior to construction of the bridge. <br /> CMC Response: The footbridge will not be installed as part of this Permit Amendment <br /> Application. A field survey has disclosed a gap between the Mammoth Millsite MS No. 17576 <br /> and the Paris MS No. 5149A that will provide access to the Pumphouse from Lickskillet Road. <br /> This open area is located entirely on the CMC owned Gold Gulch unpatented lode mining claim. <br /> 9) The operator's response to item no. 21 includes maps of the Times Mine and Wynona Mine <br /> which were drawn in 1947 and 1934 respectively. These maps do not provide enough details of <br /> the workings to sufficiently depict the proposed water storage scenario. Please provide a <br /> generalized cross-section of the area between the Times Mine portal and the mill site, showing <br /> all underground workings proposed for water storage, including the connection between the <br /> Times and Wynona Mines. This cross-section should also include surface features such as the <br /> location of the Times Mine portal, Sunshine Canyon Drive, features associated with the mill site, <br /> and the shaft from which water would be pumped from the workings to the mill. <br /> 4 <br />
