Lynn Mayer Shults of L.G. Everist, Inc. was present during the inspection. The site is located 2 miles northwest of Fort Lupton in Weld County, Colorado. The Division holds a reclamation bond in the amount of $526,000.00 The Division received the AR-O1 release request on November 7, 2007. The operator is requesting the release of 5.192 acres of permitted acres. The 5-acre area is located in the northeast corner of the Swingle North Pit. This area is within the permit area but was never mined due to the house and outbuildings located on site. Fred Dodge, the landowner of the 5- acre parcel, was present during an inspection of the site. Snow cover was present, but it was apparent that no mining or any mining related disturbance has taken place. L.G. Everist will need to submit updated maps (Mine Plan and Reclamation Plan Maps) reflecting the removal of the 5-acre parcel from the permit area. Revised maps will need to be submitted by March 3, 2008. Failure to do so will result in the Division denying the AR-O1 application. The Division inspected the active areas of the Fort Lupton Site. Mining is currently taking place in the Hill Oakley property. Mining started in this area in 2007 and will last for approximately 5-6 years. A slurry wall barrier has been constructed around the perimeter of the site to prevent groundwater from entering the pit. The slurry wall has been approved by the Office of the State Engineer and was previously submitted to the Division. In some places the pit is 50 feet in depth and in other areas it ranges from 20 to 25 feet. The operator stated that the topsoil salvage depth ranges from 6" to 18". The operator is also mining in the Golden Pit. Slopes of the Golden Pit have recently been regarded to approximately 3h:ly. Concrete piles were noted on site that have been imported into the permit area. L.G. Everist stated that the concrete is recycled on site and sold as a product, use'd'as material to make French Drains and/or used to stabilize pit slopes. In accordance with-Rule 3.1.5(9) of the Construction Materials Rules and Regulations, if an operator intends 'to backfill material generated from outside of thd'~~pproved permit area the operator must notify the Division in writing.
