n <br />r <br />Carol Russell <br />CMLR <br />Page 2 <br />September 17, 1981 <br />Upon completion of mining, Dorchester Coal Company would reclaim <br />the substation by removing all manmade structures; salvaging <br />power poles, power lines and transformers; and disposing of <br />concrete in the mine portals or the County dump. Topsoil would <br />be replaced over the transformer site at a depth of 6"-12", <br />seeded and mulched as specified in Dorchester Coal's Reclamation <br />Plan. <br />Dorchester Coal Company is also requesting approval from Colorado <br />Mined Land Reclamation for the addition of a rotary coal breaker <br />and a 75-ton rock bin to be placed in the rata coal belt <br />line to the Preparation Plant. The breaker would be part of <br />the Prep Plant operations. The breaker is rated at 250 T/hr <br />and is enclosed for dust control; since the coal is wet, very little <br />dust should occur. Water sprays would also be used should dust <br />become a problem. The purpose of the breaker is to help remove <br />rock from the coal. The rock comes from a split in the coal seam <br />that is taken while mining the coal. Rock separated from the <br />coal in the breaker would be collected in the rock bin_and treated <br />as coal waste. The rock would then be_ removed from the bin and hauled <br />by truck to the waste disposal area. -The-coal breaker and rock bin would <br />be salvaged upon completion of mining. <br />Upon approval of this plan Dorchester Coal Company will incorporate <br />it into its current Colorado Mined Land Reclamation Permit. <br />If you have any questions, please feel free to call me. <br />Sincerely, <br />~~ . <br />Darrel Hespe <br />Environmental Coordinator <br />DH:sh <br />ENC <br />CC: C.
