1 <br />' S~ <br />' EXHIBIT C - PRE-MINING AND MINING PLAN MAPS <br />' IMMEDIATELY ADJACENT SURFACE OWNERS OF RECORD <br /> The riprap quarry area is owned by the Municipal Subdistrict, <br /> Northern Colorado Water Conservancy District. The riprap <br />' quarry area is bounded on the west, south and east by lands <br /> owned by the Northern Colorado water Conservancy District. <br /> The east-west road immediately north of the quarry area is <br /> a public road owned by Grand County. There are no power <br />' lines, structures, or oil and gas wells located within 200 <br /> feet of the riprap quarry area. <br /> <br /> WATER RESOURCES <br /> A small unnamed stream flows immediately to the west of <br />' the riprap quarry area. This small stream is a tributary <br /> to Willow Creek. No other water resources are adjacent to <br /> the riprap quarry. quarrying activities are not expected to <br />' have any impact on the stream. No direct drainage from the <br /> mined area will be allowed in the direction of the stream. <br />' <br /> TOPOGRAPHY <br /> Figure C-1 (envelope) shows the existing topography of the <br />' riprap quarry area. The quarry area is located on a massive <br /> basalt formation which is a ridge rising approximately 250 <br /> feet above the surrounding plain. The ridge runs in a north- <br />south direction. The natural topography of the ridge has been <br /> previously disturbed by previous use as a riprap quarry area. <br /> This occurred on the northerly slope of the ridge and is shown <br />' on Figure C-1. <br /> Figure C-2, "Mining Plan Map", shows the topography and <br /> profiles of the quarry area on completion of mining operations. <br />' Mining will be initiated on the southerly face of previous <br /> mining activities and proceed in a southerly direction. <br />' The previous borrow activities were conducted during the <br /> 1950's and involved mining of riprap material for construction <br /> of the Willow Creek Dam and Reservoir. These activities were <br />' conducted prior to enactment of the Mined Land Reclamation Act. <br /> Figures C-3, C-4, and C-5 document the general impact of <br /> previous mining operations. <br /> Figure C-3 is a view towards the northeast across the previously <br /> mined area. Figure C-4 is towards the east from the approximate <br /> same location, and shows the midsection of the mined area. <br />' Figure C-5 is a view towards the south showing the north <br /> facing slope of the~previousTy mined area. 1 <br /> ~ ---- -- <br /> C-1 <br />
