Memo - Matt Hayes - 2 - February 23. 1990 b.) The Elk Creek area will have all structures except the water supply tank and possibly the loadout removed. The area will then have minimal grading done (to promote positive drainage?). Same areas "where the refuse layer is thin ." (see page 2.05-28) will have the weathered gob removed from them and put elsewhere in low spots. The specific areas that will have the gob (refuse) removed from them are not identified on any maps or described in the text. The specific areas that will be badcfilled with gob are not identified either. Most of the area will then be topdressed with six inches of material obtained from the road supply yard area, the portal nose area, and the upper part of the yard culvert excavation for restoration of the Elk Creek channel. The operator estimates that 18,885 cubic yards of material will be obtained by excavation of the yard culvert and the planned Elk Creek channel. The trapezoidal channel that is planned is twelve feet wide on the bottom and has 2H:1V side slopes. My calculations indicate that to get sufficient borrow material along the 380 foot channel the operator will need to excavate a channel that is approximately 3.5 feet deep. The operator has indicated that it is assumed that this material will be suitable as a plant growth medium. I have been unable to locate any soil test results that would support this assumption. However, keep in mind that probably just about any soil-like material would be better than what is now on the surface of the areas to be topdressed. So, if native material was used to bed the yard culvert that material is probably desirable to use as a topdressing. Areas that would receive this topdressing material (specified on page 2.05-28) are the outslope of the west bench, the central yard, and the east bench. My rough calculations, using measurements from Map 16, indicate that the stated material balances on Map 16 and in Appendix K are fairly accurate. The new gob disposal pile will be covered with approximately two feet of material from the topsoil stockpiles to the east and west of it. I could not find any map that delineates the location of the topsoil stockpile to the east of the new gob disposal pile. c.) The upper Bear Creek degas well area will be regraded as stated in Appendix L. I believe that the present reclamation plan for the pre-law areas is adequate. 2.) The operator's present plans for reclaiming post-law areas include the following: a.) The upper Hubbard Creek area will be left leveled as a parking area fora r"orest Service trail head. Topsoil which was salvaged will be used on the regraded sediment pond and highwall areas. Appendix L - contains plans and safety factor calculations for the final contours.
