1 ~~o~ o a- ~t5~ <br />with the reclamation plan and the requirements of the Phase I Bond Release. This <br />area will need to be taken care of before the Division can propose a decision. <br />Refuse Pile and Surrounding Areas: <br />Rock Dust Storage Tank -The rock dust tank has been removed and the gravel from <br />the pad has also been removed. The drainage from the pad goes through an SAE <br />(silt fence). <br />Refuse Pile -The refuse pile has been covered and topsoil has been replaced on the <br />pile (although topsoil replacement is not a Phase I Bond Release criteria). The final <br />configuration of the pile appears to conform with the approved post-mining <br />topography. A pit was dug with a backhoe on the west side (slope) of the refuse pile <br />to determine if the four foot cover requirements (including subsoil and topsoil) have <br />been met. The pit was dug four feet deep and there was no refuse at the bottom. <br />Ms. Saunders was concerned about a portion of the pile on the northwest corner <br />where cover may be less than four feet. The Division will evaluate that on the follow- <br />up inspection. <br />Waste pile certification reports have been submitted to the Division on a quarterly <br />basis by an independent engineering company. These reports indicate that pile <br />stability and compaction requirements have been met. <br />Drainage off of the pile flows into the 100-year ditch then into pond 4. The 100-year <br />ditch around the refuse pile has been established. There was a question regarding <br />whether the flow of the ditch has positive drainage in a couple of spots (one on the <br />northwest corner and one on the south side) to pond 4. The Division will do a follow- <br />up inspection to survey these areas to determine their grade as well as verify <br />construction with the approved design. <br />There are still several power poles and power lines on the ground in the area of the <br />refuse pile, pond 3 and pond 4 that need to be removed. <br />Borrow Area and Topsoil Stockpile -The borrow area has been regraded and the <br />area appears to conform with the approved post-mining topography. Topsoil does <br />remain in the topsoil stockpile on the south side (which will be used to cover pond 4 <br />following phase II Bond Release). Ms. Saunders and Ms. Paula Coulter were <br />concerned about the final topography and the removal of the access road in this <br />area. They were concerned excess borrow material had been removed and <br />created an unnecessary depression in the area. Drainage from these areas is <br />designed to flow into pond 4. As mentioned above, the grades will be surveyed on <br />the DMG's follow-up inspection. If the light-use road is to be re-built, a letter <br />requesting the road as a permanent facility must be provided by the landowners. <br />Pond 4 -Pond 4 was well vegetated and appeared to be stable. There was a small <br />amount of water in the boffom of the pond. White salt deposits were also visible. The <br />pond was cleaned in conjunction with the final grading/covering of the refuse pile <br />and has adequate sediment storage volume. The pond design was recently <br />changed to a self-dewatering pond. The Division needs an as-built certification for <br />
