6.4.3 EXHIBIT C -Pre-mining and Mining Plan Maas) 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 aze 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 azea. 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 azea azound each pole of a diameter of at least 20 feet with slopes developed a[ 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 jeopazdized by the mining operation. A large irrigation ditch, know as the Gurley Ditch, lies to the east of the permit area. A 50 foot wide buffer zone between the centerline of the irrigation 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 azea. This crossing will be over an existing lazge diameter culvert. This culvert is approximately 195-feet long and is constructed of a series of 8-foot diameter steel tanks. A stiffening ring was left when the ends were cut out of the tanks. The resultant minimum inside diameter of the tanks is approximately 7-feet. Agreements with the irrigation ditch owner (Farmers Water Development Company) to mine within 50 feet of the centerline of the ditch and cross the ditch is presented 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 along the south line of the permit boundary include a bazbed wire fence and an 8-foot high game fence. The game fence is owned by Tom Farmer. The barbed wire fence is owned by Tom Farmer and adjacent property owner Allen or Williams depending on the location. There is a fence that separates the Allen/Williams property that runs through the permit boundary in an east west direction. Allen owns a fence that meanders along the north side of the permit boundary. This fence is located south of the Allen/DeJohn property line so it is owned by Allen. Allen also owns a fence that meanders in a north south direction trough the proposed disturbed area. DeJohn owns a fence that touches the north line of the permit boundary. There aze three fence owners within 200 feet of where the pit access road intersects County Road 37.00. A Williams fence parallels County Road 37.00 to the north. The Fatmer Fences Pazallel County Road 37.00 to the south. The McCallan Fence is located to the east of County Road 37.00. Agreements with the fence owners Marilyn Allen and Lila Williams will allow the Operator to remove and replace their fences as necessary to facilitate the mining operation. The agreements are included in Exhibit S. The fences, including the 8-foot high game fence, located along the 12/02 C - 1
