NININfi PLAN <br />INTERFACING WITH OVERFEAD LINES AND GAS LINES: Near the north end of the <br />• gravel deposit is an easement that contains a gas line (owned by Colorado <br />Interstate Gas) and a small overhead line that extends through the same <br />ea__..~..t. Neither of these features will be moved to mine the gravel <br />contained in that corridor. Gravel mining of the small amount of gravel <br />located north of the corridor will be accomplished in the same way as mining <br />gravel south of the corridor. The gravel from this north end will be hauled <br />by truck across the corridor an crossings located by agreement with the <br />parties controlling the gas line and the overhead line. <br />Colorado Interstate bas indicated that their preference is for the <br />operations to stay 50 feet on either side of the actual gas line location. <br />Prior to mining in this area, which will be many years in the future, Colorado <br />Interstate Gas will locate exactly where the line runs and the actual areas of <br />mining will be controlled by that line. The same approach will be used on the <br />overhead line. It should be noted that although the easement is a fairly <br />straight line across the area where the gravel exists, it is not necessarily <br />true that the gas line is centered in the easement. Thus the need to <br />precisely locate the gas line on the ground before mining near the gas line. <br />. Decisions on exactly where crossings will occur will depend m the <br />location of overhead line poles and the recomnEndatims of Colorado Interstate <br />Gas regarding crossings. In our discussions it was indicated that additional <br />material might need to be laid on top of the gas line prior to establishing a <br />crossing, but they indicate gas lines are usually deep enough that crossing <br />even with loaded gravel trucks is not a problem. <br />When the mining proceeds northward to a point 750 feet from the gas line <br />corridor, locating the crossings and actual limit of mining to the south and <br />' the north of the gas line will be established. The same procedure will be <br />used for the overhead line. <br />MINING/RECLAMATION RELATIQ~ISHIPS: Because there are no phases in this <br />mining plan, it is necessary to discuss how far behind the mining process the <br />reclamation will occur. To conduct the mining and its associated processing <br />and stockpiling a certain minimum amount of land is needed between the working <br />gravel face and the reclamation. This amount of land is not easy to identify <br />because there are so many variables that control its dimensions. <br />r <br />LJ <br />Page 9 <br />
