S E N E C A C O A L S, CAMPUS SIx OFFICE BUILDING SUITE 600 12015 EAST 46TH AVENUE DENVER, COLO RADO 60239 TELEPHONE 1303) 371-7990 Ms. Sandy Emrich Reclamation Specialist Mined Land Reclamation 1313 Sherman Street Denver, Colorado 80203 Dear Sandy: LTD . December 29, 1981 ~~~~'~~~ III IIIII~IIIIIII III DEC 3 U 1981 MINED LAND IILCLAMATIGN Colo. Dept. of Alatural Rzsources Thank you for the opportunity to further discuss the question of shrub densities on reclaimed lands at Seneca II. As per our conversation and based on the fact that a shrub density value has not been proposed by the state, the following program will be implemented over the next year to arrive at an acceptable shrub density standard as stated in the MLR stipulation. As discussed on page 13-10 of the Seneca II Permit, the proposed planting of shrubs will be at a density of 300 per acre in concentrated "groupings" or "islands". It was also stated that a much higher density will actually be achieved due to natural regeneration and reinvasion. Research at other mines and actual conditions occurring on reclamation at Seneca II support this. It is proposed that Seneca Coals, Ltd. collect shrub density infor- mation on reclaimed areas in order to arrive at a more "concrete" shrub density standard. A basic outline of the proposed program is presented: 1. Shrub density data on reclaimed areas at Seneca II will be collected during the field season of 1982. 2. Shrub density data plus shrub species present will be collected on three (3) areas of reclamation: reclaimed spoil, reclaimed areas with topsoil from stockpiles, and reclaimed areas with topsoil that has been direct-hauled from topsoil stripping areas. 3. An adequate sample size will be collected from each of the three proposed study areas.
