CMC Response: CMC is providing a Generalized Cross-Section of the Times Mine Cross-cut <br /> below Sunshine Canyon Drive with the 50 foot winze that connects to the Wynona Mine's 100 <br /> Foot Level. The Times Mine Cross-cut and the Wynona Mine workings are where the water <br /> from Left Hand Creek will be stored for processing ore in the Gold Hill Mill. This water will be <br /> drawn from these mine workings from drill holes and pumps that will be connected to these mine <br /> workings. <br /> 10) Please clarify how the operation intends to access the waterline easement for pipeline <br /> removal, installation, maintenance, and reclamation. Does the operation intend to access the <br /> waterline from Lickskillet Gulch? If so, does the operation have a legal right to cross the <br /> property between the road and the easement for this purpose? <br /> CMC Response: As set forth in the Permit Amendment Application in EXHIBIT G— SOURCE <br /> OF LEGAL RIGHT TO ENTER in the Affidavit Concerning Right to Enter Mining Claims, the <br /> Water Pipeline Easement Deed with Boulder County states that said Deed granted a permanent <br /> non-exclusive easement on and under said Property for the purpose of: <br /> "Access to and to maintain, repair and improve the existing water pipeline along Lick Skillet <br /> Road for the purpose of supplying water from Left Hand Creek to the Gold Hill Mill for Mining <br /> and Processing Ore." (Affidavit Exhibit A) <br /> CMC will access the Water Pipeline Easement for pipeline removal, installation, maintenance, <br /> and reclamation using the four historic mine roads that provide access to the Gold Hill Mill <br /> Waterline. The legal right to cross the property between the County Roads and the Gold Hill Mill <br /> Waterline was preserved in the Water Pipeline Easement Deed with Boulder County. <br /> 11) The operator's response to item no. 23 states the Times Mine bulkhead is situated 100 feet <br /> from the metal door of the 5 foot diameter galvanized steel culvert that provides entrance into the <br /> mine. This bulkhead is 3 feet thick and was constructed of concrete and rebar in a wooden form <br /> in 1987. There are 3 PVC pipes set within the bulkhead, including a 3-inch intake pipe, a 2-inch <br /> pipe, and a 1-1/2- inch pipe, all closed with ball valves. The operator submitted a rudimentary <br /> drawing of the existing bulkhead, presumably from the portal side, indicating approximate <br /> locations of the three pipes. The description and drawing submitted do not provide enough <br /> details for the Division to determine whether the bulkhead was properly designed and installed to <br /> be utilized for the proposed water storage. Please provide more details on the design and <br /> construction of the bulkhead, including a description of the competency of surrounding bedrock, <br /> whether any portions of the surrounding rock were pressure grouted to minimize water seepage, <br /> demonstration the bulkhead was designed to withstand the maximum hydrostatic pressure for the <br /> proposed water storage, demonstration the bulkhead is sufficiently thick and properly anchored, <br /> and an estimated thickness of overlying overburden. <br /> 5 <br />
