~:' -~ <br />and might be appropriate to remain in as a permanent stock pond if the land <br />owner so requests. The sediment pond below the refuse pile is also still in <br />and functioning properly. The western drainage of the refuse area was <br />established and rip rapped in 1986. Avery low grade exists on the channel in <br />the upper portion, however, sightings along the channel assured that there is <br />a positive drainage on this channel. After sediment pond removal at the <br />refuse pile the permanent channel for the two drainage sections leading off <br />the refuse pile will need to be established down to the North Thompson Creek. <br />The bond has been calculated to assure that sufficient funds remain to reseed <br />and mulch if the vegetation were to fail and to regrade the existing sediment <br />ponds, establish the final drainages down to the river, and repair the Seavers <br />Ditch for the five year liability term on that ditch. These calculations <br />include revegetation of the load out areas also. The Division calculated <br />approximately $38,000.00 required to accomplish all these tasks. The amount <br />of bond that will remain after this reduction will be $300,000.00 so, the <br />Division believes the mine is well covered for arty work that might be required <br />at the site. <br />Overall, both Dennis Burns and I felt that the reclamation work accomplished <br />at the mine and at the load out is exemplary. Even very small areas of <br />disturbance such as little access roads had special attention paid to <br />feathering in the edges of all the reclaimed section with the undisturbed <br />areas. <br />The No. 1 Mine portals have been sealed with hydraulic seals. The No. 3 Mine <br />is being allowed to drain through its pre-existing pipe to the river. A <br />concrete well exists just down the downslope of the old 3 Mine bench that <br />allows for sampling of the discharge water. The new NPDES permit for this <br />site will be monthly sampling for Ph, flow, and oil and grease. The water has <br />always been a good quality and no problems are expected to occur from this <br />discharge. The land owner, Mr. Perry, expressed the interest in diverting <br />this mine flow to irrigate the No. 1 Mine reclaimed area in order to more <br />quickly establish the vegetation. He was cautioned that any diversion of such <br />water need to be approved by Snowmass Coal Company and must remain in <br />compliance with our regulations. Snowmass Corporation has an agreement with <br />Fourmile Mineral and Land Corporation over controll of the mine site reclaimed <br />area fora 10 year period. Grazing will not be allowed until Snowmass <br />Corporation and the Di vi sion so approve i t. <br />Weather conditions prevented access to the Middle Thompson Creek area of the <br />mine. There is an old fan portal over on that side of the area which has not <br />been checked. The Division will fly this area in late December to check on <br />the status of reclamation for this site. <br />Mr. Dwayne Gilfrey the local Ranch Manager of the Anschutz holdings, <br />accompanied us on the inspection of all the load out areas. The macadem road <br />leading out to the old truck dump area has remained in place along with the <br />turn around pad for the truck dump. A11 the structures of the truck dump and <br />the conveyor have been removed and the entire area seeded and mulched. The <br />truck dump turn around area will be utilized by the ranch for hdy storage. <br />Mr. Gilfrey stated that he is very pleased with the status of reclamation at <br />the area. <br />
