CMC Response: The only small area that will be disturbed for the burial of the new two (2) inch <br /> HDPE pipeline is located along the Water Pipeline Easement Deed and within the proposed <br /> affected area. <br /> 5) The operator's response to item no. 18 states the maximum total volume of fuel to be stored at <br /> the pump house is 300 gallons. The fuel will be stored in a standard metal container approved for <br /> fuel storage. The Bean pump and generator will be installed within metal containment frames <br /> that will retain any fuel or lubricants inside the pump house. Please clarify whether the fuel <br /> storage container will be double-walled. Additionally, please provide details on the proposed <br /> secondary containment, including whether it will hold 110%of the maximum storage volume (in <br /> this case, 330 gallons). If the fuel tank will be double-walled, its outer shell capacity may be <br /> included in the 110% volume calculated for secondary containment. <br /> CMC Response: The maximum total volume of fuel that will be stored at the pumphouse is 300 <br /> gallons. The fuel will be stored in a standard single-walled metal container approved for fuel <br /> storage. The fuel storage container will be placed within a secondary containment sump which <br /> will hold at least one-hundred and fifty (150%) percent of the maximum storage volume of the <br /> actual fuel tank selected for this site. This fuel containment sump will be constructed of HDPE, <br /> and therefore will not rust or corrode. This sump will be purchased at the same time as the fuel <br /> storage tank and will be large enough to contain more than the maximum volume of the fuel <br /> stored at the pumphouse. <br /> 6) The operator's response to item no. 19 states there is no other existing infrastructure to <br /> remove other than a 3-inch and a 2-inch PVC pipeline. Other portions of the amendment <br /> application refer to only one existing 2-inch pipeline. Please clarify if there is more than one <br /> pipeline that needs to be removed. Also, please provide an estimate of the maximum length of <br /> pipeline to be removed prior to installation of the new pipeline. Please be sure the reclamation <br /> bond estimate includes costs for removing all existing pipeline. <br /> CMC Response: There is only one existing pipeline in place on the Water Pipeline Easement. <br /> Most of it is three (3) inches in diameter. Some of it is two (2) inches in diameter. This was <br /> described in the Amendment Application in Section 14.: Description of Project as follows: <br /> "The Gold Hill Mill's Waterline was initially installed in 1987, with a three (3) inch pipeline that <br /> extended from Left Hand Creek to the Times Mine adit portal. Water was pumped from Left <br /> Hand Creek on numerous occasions by the then permitted operator, Gold Hill Ventures, Limited <br /> Partnership. During the period that COM, Inc. was the permitted operator of the Gold Hill Mill, <br /> the lower portion of the water pipeline was replaced with a two (2) inch pipeline, and water <br /> was pumped to the Times Mine on several occasions during the period when the mill was <br /> controlled by that operator. A portable Bean pump was used to pump the water from Left Hand <br /> 3 <br />
