Colorado Inactive Mine Reclamation Program CLOSEOUT REPORT ACTIVE MINE BOND FORFEITURE PROJECTS Permit Information Permit Number Operator Name Mine Name C-1981-015 American Shields Coal Co. Fruita No. 1 & No. 2 Type of Mine— Underground Commodity Mined- Coal PRE-RECLAMATION SITE CONDITIONS The Fruita Mine is an underground coal mine located approximately 10 miles north of Fruita in Mesa County, Colorado. A mining and reclamation permit was issued by the State of Colorado in 1981. The permit was revoked and the financial warranty forfeited by the State of Colorado in 1994. The site was reclaimed using the forfeited bond money in 1996 and in 2000. Reclamation work included grading, erosion controls and revegetation. Since the site was last reclaimed in 2000, a number of erosion features have developed that require repair and maintenance. The project work will include removal and plugging of the corrugated metal pipe spillway in the sediment pond, grading and lining of the sediment pond spillway, maintenance and repair of several rock lined channels, armoring above the mine portal and revegetation of all newly disturbed areas. In addition, surface water runoff from undisturbed areas has migrated into one of the portal backfilled areas. The area will be excavated to determine the extent of previous backfilling done on the portal.

Work started in the main drainage channel at the transition between the rock and the earth lined channel. Approximately 250 feet of drainage channel was constructed from the end of the existing rip rap channel (the upper portion of the fill channel was constructed in 2000 by AML under Project Manager Paul Krabacher)to the bottom of the slope. The same channel configuration and rock gradation was used from the 2000 design. Excavation and placement of the channel required side slopes no steeper than 3H:1 V, eight (8)foot bottom using rock available on site. Rock sizing consisted of a combination of 20% minimum 4 foot diameter rock, 40% minimum 2 foot to 3 foot diameter rock and 40% 12 inches to 18 inches diameter rock. The mine portal area backfill extends up against a sandstone outcrop. During large storm events, water from the Bookcliffs was draining into the portal backfill and creating an opening between the sandstone and fill material. The hole was excavated revealing an opening in front of the bulkhead seal approximately 30 feet wide by 35 feet deep. Layers of Polyurethane Foam (PUF)and rock were used at the portal entry to act as a seal and prevent water from migrating into the portal. The portal was then covered and compacted with fill to the original grade surface. Lastly, a large rock apron was placed on top of the compacted backfill to direct surface water flows into the constructed drainage channel. Additional rock channels were constructed on the northern drainage, the confluence of the two drainages and the road drainage using rock available on site. A number of rock check dams were installed by hand on the south side of the fill and the main access road to address the numerous rills and gullies. Rock check dams were also placed below the reconstructed channels to further protect the channel during high velocity storms. A total of 555 feet of rock lined channel and 34 rock check dams were installed on site during this project.
