• <br /> I <br /> This proposed decision is to release from bond and liability all backfillino <br /> and grading work which has occurred at the mine site and loadout to date <br /> except that additional bond will be held to reclaim a portion of the truck <br /> dump road located on prime farm land. An additional bond amount of $45,000.00 <br /> will be held to reclaim approximately 2 acres of prime farm land disturbed by <br /> the truck dump road. Bond shall also be retained in an adequate amount to <br /> cover reclamation of sediment ponds and ditches, and to ensure the successful <br /> establishment of vegetation; including soil preparation, seeding, mulching <br /> and netting and other methods as described in the approved reclamation plan. <br /> This approval is based on an inspection of the site and evaluation of <br /> reclamation results. The bond currently held by the Division is <br /> $1 ,750,000.00. The bond liability recalculated by TR-7 is reduced by <br /> $945,700.00. The remaining bond amount is $804,300.00. This approval <br /> document approves the release of 60% of this amount or $482,580. The current <br /> bond of $1 ,750,000.00 shall be reduced to $321 ,720.00 when all statuary notice <br /> and public comment requirements have been met. This is more than enough bond <br /> to cover any outstanding reclamation concerns. <br /> Evaluation <br /> All buildings, structures, and facilities at the mine site and loadout have <br /> been dismantled and removed. Backfilling of the refuse area was done in <br /> accordance with a technical revision approved July 2, 1986. Channels were <br /> installed in accordance with a technical revision approved February 10, 1987. <br /> The mine site and truck dump were reclaimed in accordance with a plan <br /> submitted in a technical revision and approved September 7, 1987. The loadout <br /> was reclaimed in accordance with the permit application reclamation plan. <br /> The mine site reclaimed areas drain to three sediment ponds. The NPDES <br /> permit, CO-0029599, requires monitoring of outfalls 002, 005, 006 and 007. <br /> Outfall 004 was a sewage lagoon which has been reclaimed. A perpetual <br /> discharge has been approved at the No. 3 Mine (Outfall 007). This discharge <br /> is meeting water quality standards. Monitoring frequency for this site was <br /> reduced from weekly to monthly for oil and grease, flow, and pH. The No. 3 <br /> mine regraded area drains down the county road to the upper most sediment <br /> pond, or NPDES site 006. The main portion of the No. 1 mine drains into the <br /> pre-existing sediment pond 8 (NPDES site 002) The refuse area and a small <br /> portion of the mine site drain to the refuse sediment pond (NPDES site 005). <br /> Soil sampling of the regraded areas at the loadout and the mine were submitted <br /> by the operator to the Division. Division review found that the replaced <br /> topsoil materials were valuable as plant rooting media and the proposed <br /> fertilizer application adequate to alleviate defficiencies and enhance plant <br /> growth. All areas of the mine site, refuse area, and loadout have been seeded <br /> and mulched where required accept for an area at the loadout to be planted in <br /> alfalfa during 1988. The refuse area was reclaimed in 1986. Good growth is <br /> establishing on the refuse area. <br /> -3- <br />
