TR9PPER MINING INC. <br />iii ~iii~niiiii~iii <br />999 <br />RECEIVE <br />October 10, 1991 <br />Mr. Kent Gorham <br />Colorado Mined Land Reclamation Division <br />215 Centennial Bldg. <br />1313 Sherman St. <br />Denver, CO 80203 <br />OCT 15 1991 <br />Mined Land <br />Reclamation Division <br />Dear Kent <br />This cortespondence summarizes the proposed sedimentation pond construction activities at Tr r Mine <br />during the 1991 field season. A total of five sediment ponds were proposed for construction or m 'ration <br />during 1991 of which only two were completed (West Pyeatt Gulch and Johnson Gulch Pond #9). The <br />completed West Pyeatt and Johnson Gulch #9 pond construction was approved by the Division in technical <br />revision 51 and 55 respectively. Additional ponds proposed and approved by the Division for construction <br />included the Deer Gulch (MR10'7), Johnson #10 (TR-55), and Far East Buzzard (CR-57) sedimentation <br />ponds. These three ponds will not be built or modifications performed during 1991. There are several <br />reasons these ponds were not conswcted in 1991 and include 1) an extremely productive topsoil replace- <br />ment field season that took precedence over pond construction; 2) the extent of the disturbance in several <br />drainages was less than originally Forecast and did not necessitate pond construction; and 3) our long range <br />mining plan questioned the proposed location of one of the sedimentation ponds (Far East Buz?ard). <br />Trapper intends to construct the remaining three sediment ponds during the 1992 reclamation field season. <br />If the loption or design of any of these sediment ponds changes, Trapper will submit all appropriate infor- <br />matlon to the Division for approval prior to construction activities. If no changes or modifications are nec- <br />essary, Trapper will initiate wnstruction as early in the field season as is practical. <br />Kent, if you have any questions or concerns, please contact me. <br />Sincerely, <br />William Agnew <br />Sr. Environmental Engineer <br />IWCat1RD~ocno( <br />c EG ]ohriwn <br />J.M.
