• ~~ lll. EXHIBIT C - PREMINING PLAN AND AFFECTED LANDS Exhibit C is intended to fulfill the requirements of Sections 34-32-112 (4), subsections (c), (e), (f), (g) and (i) of the Colorado Mined Land Reclamation Act as outlined in the Mineral Rules and Regulations of the DMG and the Boazd. Generally, the required information relates to adjacent properly ownership, the name and location of surface features and structures within 200 ft of the boundaries of the affected land, existing topography, the total area of mined and affected lands, vegetation and other soils and water resource information as required by the Division. Adjacent property ownership for the Morrison quarry is portrayed on the accompanying Figure C-], Adjacent Property Ownership. Property ownership remains the same as that which existed at the time of submittal of Amendment No. 2 in 1982 and Figure C-1 is presented herein as provided in Amendment No. 3 in August 1993. ~ince the ime of Amendment No. 3, the Cooley property has been annexed into the Town of Morn n from unincorporated Jefferson Zount~on was accomplished by a "flagpole" annexation from orrison south on Highway 8, west on U.S. 285 and then north to the subject propetty. The annexation was passed by a unanimous vote of the Town Board of Trustees on 25 October 1994. Cooley worked together with the Town of Morrison to develop a mutually beneficial annexation agreement that creates an option for the Town to obtain raw water storage capacity within a bedrock reservoir(s) at the quarry site. Mining and reclamation exhibits included in this amendment reflect this fundamental change in ultimate land use strategy for the facility. • Dooley subcontracted for new aerial photography to be flown of the quarry area in August 1994. /This new photography was then digitized to create current topographic base maps for use in the preparation of this mining and reclamation plan amendment and for conducting additional geotechnical evaluations of pit slope stability within existing and future mined areas. Surface features such as creeks, roads and buildings aze shown on a map of current conditions at the quazry (i.e., "premining" ~_;tl` conditions, with respect to this proposed amendment). A power line is shown at the southern limits r of the proposed affected land which is owned by Mountain States Telephone and Telegraph Company as part of aright-of--way. Prior to mining within 200 ft of the power line, Cooley intends to initiate Q`-' appropriate notification of the utility owner and institute required relocation of the line, maintenance ~ of safe distance sepazation and/or engineering controls to ensure safe mining operations in that area. The premining topography of the area is shown on Figure C-2, Exhibit C - Premining Plan, which shows August 1994 topography depicting the results of mining and reclamation activities to date under the current permit and amendments. The total azea to be involved in the operation, including mined areas and areas of affected land, comprise approximately 182 acres. This total acreage reflects an increase of approximately 48 acres over the presently approved total acreage of 134 acres. The increase represents: 1) an increase of approximately 38 acres of minable reserves in the North Quarry area; 2) an increase in limits of disturbance in the vicinity of the failed East Highwall in the Central Quazry as described in detail in Amendment No. 3; 3) an increase in the limit of disrurbance in the North Quazry to facilitate access to the older west highwalls and benches to perform more modern reclamation; and 4) a minor increase in the limit of disturbance along the east side of the South Quazry area for access to initial mining there. • .:wmw.e.aoo Ili-1 ~~~
