-~(- in the Marr Strip mine application (Volume I, page 779-103) and confirmed by telephone conversation with Al Whitaker of the Colorado Division of Wildlife, the CDOf/ is considering reclassifying the status of Johnny Darters from "state threatened species" to the status of "concerned species" in the State of Colorado due to the extensive populations of the fish found in North Park. As there are no adverse impacts expected on the Canadian.or Plichigan Rivers due to the proposed operations at the Canadian Strip mine site, this Division makes the finding that the proposed mining activities at the Canadian Strip mine "would not affect the continued existence of endangered or threatened species or result in the destruction or adverse modification of their critical habitats" (2.07.6(2)(n)). XIII. Prime Farmland (2.04.12, 2.06.6, 4.25 The Division has made a negative determination for the presence of prime farmland within the proposed permit area. The decision is based on the letter of August 6, 1979, signed by Kenn Lutz, District Conservationist of the .Soil Conservation Service, stating that there are no prime farmland mapping units within the proposed permit area. This letter can be found in Appendix I of Volume III. XIV. Operations Description (2.05.2, 2.05.3(1), 2.05.3(2), 9.02) The applicant has supplied alt information required by Sections 2.05.2, 2,05.3(1), 2.05.3(2) and 4.01 of the Regulations. The detailed description of the operations at the Canadian Strip mine az'e contained in Volume I, pages 25-57 of the April 14, 1981 application. In brief, the existing operations in Pit 1 are a single spoil ridge open pit mine. The mining is progressing south along the eastern limb of the McCallum Anticline, and has disturbed about 80 acres of land. Approximately 24 acres of land have been mined, backfilled, retopsoiled and seeded. There are 22 acres of Zand covered by the 1,300,000 BCY overburden stockpile, topsoil stockpiles and sediment ponds. There are 23 acres of active pit, and the remaining 11 acres are covered by mine facilities and coal stockpiles. The dip of the coal varies from 34 to 28 degrees and the thick- ness from 12 to 22 feet. Current production is approximately 195,000 tons of coal per year from Pit I. Operations in Pit 2 will utilize an open pit haulback system of mining after the initial boxcut is moved to Pit 1. At the maximum extent of mining, about 170 acres of land will be disturbed by mining operations in Pit 1 and Pit 2. Maximum production is expected to reach 300,000 tons per year from Pit 2. Both pits will employ the same equipment to perform the required work. Topsoil will be removed using scrapers or trucks and shove.7s. Overburden will be removed by truck and shovel and will be lightly blasted where necessary. Coal is mined using either the front-end loader or hackhoe to load trucda. Trucks haul the coal from the pit to the crusher, where it is crushed to 2" x 0". Crushed coal is then hauled by indepen- dent contractor to Nanna, L/yoming for rail 2oadout.
