PROJECT WORK DESCRIPTION <br /> Al Introduction <br /> The area of mining-related disturbance at this site is approximately 17 <br /> acres. Coal was accessed at the New Pryor Strip-Pit mine by successive <br /> removal and segregation of overlying topsoil , subsoil , and overburden. <br /> This material remains on the site. Also located on the site are historic <br /> coal spoil piles. Backfilling of the strip-pits will start with historic <br /> coal spoil . When all of this material has been used, overburden and <br /> subsoil material placement and grading will follow to complete <br /> backfilling. Topsoil will then be used to bring the property to final <br /> design grade. <br /> A centrally located long pit and a joined pit/highwall complex in the <br /> southern portion of the property require backfilling (see site map) . <br /> Approximately 8.3 acres of ground have been disturbed in the development <br /> of these pits. The northern end of the project area contains stockpiled <br /> overburden, subsoil , and topsoil which was stripped prior to pit <br /> development and coal spoil from historic mining operations. Stockpiles <br /> and coal spoil piles occupy approximately 8.7 acres on site. The current <br /> relief in elevation of the site is 60 feet. Pre-mining topography slopes <br /> at a moderately shallow angle to the east and northeast. The maximum <br /> anticipated haul distance is approximately 1500 feet from the northern <br /> stockpile areas to the strip-pit zone in the southern portion of the <br /> property. <br /> Topographic maps, aerial photographs, and other related information is <br /> available to Bidders for inspection at the offices of State of Colorado <br /> Department of Natural Resources, 1313 Sherman St. , Rm. 715. Denver, <br /> Colorado. Bidders must arrange an appointment to inspect these materials <br /> by calling the PROJECT MANAGER. Randy Streufert at: (303) 866-2611 . <br /> Volumes of strip-pits and stockpiles stated in this bid document have <br /> been calculated by average end method using 50 feet centers and have been <br /> correlated with existing documentation from the strip-pit mining <br /> operation. Stated volumes are believed to be accurate: however bidders <br /> are encouraged to perform their own volume calculations. <br /> 81 Project Work Description <br /> The following tasks will be performed on this project: <br /> Task 1 : Mobilization and demobilization <br /> Task 2: Coal spoil removal and placement <br /> Task 3: Overburden removal , placement and grading <br /> Task 4: Sediment pond improvement <br /> Task 5: Topsoil removal and placement <br /> Task 6: Revegetation <br /> Task 7: Equipment rental <br /> -4- <br />
