C� Alatu'al <br /> Mr . Jim Herron <br /> Mined Land Reclamation Division <br /> 423 Centennial Building <br /> 1313 Sherman Street <br /> Denver , Colorado 80203 <br /> Re : Minor Revision - Catchment Basins Nos . 1 and 4 Nines <br /> Dear Jim, <br /> Enclosed are some maps and descriptions of the catchment basins <br /> constructed this fall--three at No . 1 Mine and one at No . 4 <br /> Mine . <br /> The three basins at No . 1 Mine range from 1 . 0 A. F. to 1 . 3 acre <br /> feet (80 ' x 120 ' x 6 ' ) and are designed to discharge in series <br /> (see Arrows on map) . We think these catchment basins will be <br /> of benefit in the reduction of probable sediment from the old <br /> road and pad fills adjacent to No . 1 "line . <br /> One basin (80 ' x 120 ' x 6 ' ) was constructed at the toe of the <br /> old north fill slope at No. 4 Mine . This location is also at <br /> the toe of one of the newly constructed test sections for mine <br /> pads . We feel that this basin will fill a twofold purpose : <br /> that is , reduce probable sediment from the old fill section and <br /> reduce sediment from the newly constructed pad fill test <br /> section . See enclosed map. <br /> If you have any questions, please call me . <br /> Sincerely , <br /> Environmental Coordinator <br /> DWBowman:ms <br /> Enclosures : Two maps <br />
