• BACKFILLING AND GRADING - RULE 2.05.4(2)(c) <br />Based on the recommendations by Rocky Mountain Geotechnical in their <br />report dated May 15, 1981 and submitted to the Division, the Bear Coal <br />Company plans to backfill their ttine No. 2 portals to approximately half <br />of the existing portal face-up height. Bear Coal Company feels this <br />would be the most practical and safest for backfilling the area and <br />making the final reclaimed surface compatible with the surrounding <br />environment. <br />Monitoring of the final backfilled configuration to determine any <br />possible stability failure will be carried out once the area is <br />backfilled. A series of three monitoring stations will be set up on the <br />backfilled material and will be monitored on a semi-annual basis for two <br />years as requested by Mr. Jim Pendleton of the Division. Surveying the <br />stations will indicate any movement of the fi1T; results of the <br />• surveying will be submitted to the Division. <br />r~ <br />U <br />-6- <br />
