6.4.3 EXffiBIT C -Pre-mining and Mining Plan Map(s) of Affected Lands A list and map of all immediately adjacent and nearby owners of record is presented in this section and on Exhibit C-3. The name and location of all creeks and roads are shown on the Index Map presented in Exhibit B. The Index Map is a portion of the Redvale, Colo. 7.5 Minute Quadrangle Map, Township 45 North, Range 14 West, N.M.P.M. There are no known oil and gas wells in the vicinity of the permit area. There is a 69 kV power transmission line which runs in a northwest to southeast direction across the mining azea. The power line is owned by San Miguel Power Association. San Miguel Power Association has provided the Operator with design requirements to be included in the mining plan for this size and type of transmission line. An undisturbed area around each pole of a diameter of at least 20 feet with slopes developed at 2h:ly is provided in the pit design. Additionally, a 15 foot wide access ramp with a maximum 15% grade will be provided at each pole. Aground cleazance restriction of 23 feet (adjusted for voltage and altitude) under the power lines is also met in the mining plan. These measures will assure that the integrity of the power line is not jeopardized by the mining operation. A lazge irrigation ditch, know as the Gurley Ditch, lies to the east of the permit azea. A 50 foot wide buffer zone between the centerline of the imgation ditch and the pit disturbance is incorporated in the mining plan. The access road for the gravel pit will cross the Gurley Ditch along the south line of the permit area. This crossing will involve the installation of a lazge diameter culvert. Agreements with the imgation ditch owner (Farmers Water Development Company) to mine within 50 feet of the centerline of the ditch and install the culvert are included in Exhibit S. Should leakage become a problem, the Operator will line or pipe the ditch along the east boundary of the disturbed area. Fences lie to the north of the permit area. One of the fences will be removed and replaced to facilitate the mining operation. An agreement with the fence owner (Marilyn Allen) is included in Exhibit S. The other fence which will not be affected by the mining operation is owned by Dr. Michael Dejohn. Planned facilities for the Allen Pit are depicted on the Exhibit C-2 Mine Plan. They include a portable screening and crushing plant, a tractor trailer type material storage shed, a diesel generator set, crushed rock stockpile footprint and portable sanitation facilities. The existing topography is presented on Exhibit C-1 Pre-Mining Map. In general, the land slopes gently to the southwest. The western edge of the pit disturbance consists of the partially exposed gravel outcrop. This 30 foot thick gravel deposit presents itself on a slope ranging from nearly level to approximately 30%. The vegetation of this slope is predominantly cedaz trees. The upper, more gently sloping portion of the pit disturbance area contains a small sagebrush community but is predominantly abandoned farmland which is neazly void of vegetation. The type of present vegetation is also shown on Exhibit C-1 and a description of the vegetation is presented in Exhibit A soils information map is presented as Exhibit I. C-1
