~~~ ;,. ar ~- na- ~~ENTENNIAL AGGREGATES, LLC. 540 Elkton Dr., Suite 202 Colorado Springs, CO 80907 (719) 955-0935 RE~',~~~/ED January 10, 2006 JAN 1 3 2006 Dr. Harry Posey IUD+~isioo of Minerals and Geology Division of Minerals and Geology Minerals Section 1313 Sherman Street, Suite 215 Denver, Colorado 80203-2273 Dear Dr. Posey: Re: Rocky Flats Pit, Annual Report for 2004 MLRB Permit # M-87-113_, Anniversary Dat ~l/~_~ The permit was transferred from Church Ranch to Centennial Aggregates in May 2005 and Centennial's current contact information is provided below. This annual report covers the period from January 6, 2005 to January 5, 2006. It addresses only gravel mining on the site at this time. Until enough gravel is removed to expose the underlying clay, no report for that material is needed. This pit HAS NOT been granted a Temporary Cessation and it HAS operated more than 180 days this year. The approved bond amount is $84,600 covering 95.07 acres ±, and the facility has one mining stage and one reclamation phase. The bond was evaluated in November 2003 so no bond evaluation is attached this year. Please refer to the attached 2005 Annual Report Map for the areas discussed in this text. We will deal specifically with the Annual Report requirements as outlined in Rule 1.15 of the Rules and Regulations and those noted in the annual letter. (1) The map prepared for this report shows a total of 33.83 acres has been stripped on the southern end of the mine to prepare it for mining (yellow/brown). The current bond covers 35.00 acres ± of disturbance. Mining is taking place in the partially mined area that is colored brown, this area covers 24.60 ac. ± of the stripped area. Material mined is processed at the plant located on the Church Pit that adjoins this mine on the west. Stoller Construction completed the landfill closure project this fall. The two interior haul roads they built across the permit area for hauling material to their project site remain but will eventually be removed as mining progresses into the area the roads lie on. Church Ranch nor Centennial Aggregates had nothing to do with constructing these roads. Where the roads lay outside the permit area D.O.E. and Stoller are responsible for reclaiming them. Growth medium is being stockpiled in berms on the mine area for use in reclamation. We completed the berm along the south side of the permit area near where the old Rocky Flats West Entrance road was built. This berm is approximately 17 feet north of the permit line. In addition, we began placing reclamation material along the northern part of the east permit line for use when reclamation begins in that area. (2) No reclamation was required this year. The site berms will be revegetated when they are complete. This berm is required by the county permit.
