~i .i • (Page 2) • B; ~ MINE ID ~` OR PROSPECTING ID / Dt-77-560 INSPECTION DATE 11/13/95 INSPECTOR'S INITIALS RCO OBSERVATIONS This inspection was conducted by the Division primarily to reassess the current level of reclamation work performed by the operator, to allow an accurate recalculation of the financial warranty required for full reclamation of the present disturbance. The operator has filed an amendment to the permit, to add 107 acres east of the present permit area. That amendment is not yet approved. The reclamation coat estimate has been recently revised by the Division, and is now being reviewed by the operator. The existing operation in the present permit area utilizes a processing and stockpile area, which is adjacent to, but outside of, the present permit. The facilities also include a cinderblock building which houses the office and some processing equipment, and nearby truck scales. The operator ie adding those areas and facilities to the permit area in this amendment. The reclamation costa for the present permit and adjacent facilities were calculated, but the figures have been revised subsequent to this inspection. Those figures are included with this report. The items noted during this inspection are described below: 1. The spur to the Crystal drainage ditch on Valco'e property has been filled with overburden from the berme along the north aide of the process area. 2. The area surrounding the drainage ditch which is to be revegetated has been graded and surfaced with overburden from the berme along the north aide of the process area. AL1 remaining elopes on the berm are being graded to 3:1. 3. The concrete rubble to be removed from the process area is still present. 4. There is still significant metal junk equipment present in the north aide boneyard in Stage Y. 5. The discharge flume on the north aide of Stage Y has been removed and ditch filled. Concrete rubble from that vicinity has also been removed. 6. All banks of the East Pond have been cleared of weeds and regraded to 3:1 or lees, with a somewhat natural-appearing, wavy topography. There has been no revegetation performed yet. 7. The pond was pumped down and the elopes which are normally underwater were also graded to 3:1, since the pond will remain as a recreational Bite. The water level has risen again. 8. Slopes of the overburden piles in Stage Y have been graded to elopes of 3:1, except their north aides, which are stable and revegetated. Newly shaped surfaces have not been revegetated yet. 9. Mining in the permit is now occurring only in Stage IV, on the west end of the Eaet Pond. As mining progresses toward the west, waste material and overburden will be backfilled into the adjacent Weet Pond. This will eliminate the west Pond's water surface, though some elopes will remain. (This moving and placing of material will keep the pond surface size constant, due to limitations of the existing water supply plan.) The backfilled material will be sufficient to cover the present water level by at least two feet. This increases the dry surface to be revegetated. The existing trees will not be affected. 10. The office building will remain, though the equipment inside and the exterior storage towers and footings must be removed. Likewise, the truck scales and concrete abutments must be removed. The remainder of features on this area are either portable equipment or stockpiles of various products, and are not subject to bonding. 11. The revegetation of the prepared surfaces will occur soon. The Colo Div of Wildlife will perform the seedbed prep, seeding and mulching. CDOW ie still interested in taking over this property for a recreational site, at which time the current operator may or may not et ill be the permittee, of all or parts of the permit area. The bond calculation for the existing permit area plus the adjacent process area is revised. The task numbers are consistent with the figures sent to the operator earlier in 1995. Attached is the revised 4-page summary form showing all tasks, some of which have been now deleted. The summary includes a couple new tasks dealing with removal of boneyard junk and facility area structures. The operator will inform the Division of any work carried out oneite, which would affect the bond amount. Later this season, the operator will report on the revegetation activities oneite, and include copies of the seed tags, to verify the species and amounts of seed drilled or broadcast, and which areas were treated.
