<br />Page 2 <br />Mr. David Shelton, Director <br />Mined Land Reclamation <br />January 20, 1981 <br />1. The basic information on DCC's Dorchester No. <br />1 Mine, as currently permitted is to be found in CMLR Permit <br />File No. 79-39 ug/c. DCC intends to submit shortly a new <br />permit application under the new Colorado permanent program <br />performance standards. This new permit application will <br />affect the same general permit area. <br />2. Exhibit 1, attached, is entitled "Index Map" <br />and which shows the general vicinity and major surface water <br />systems near the Dorchester No. 1 Mine. <br />3. Exhibit 2, attached, is entitled "Location Map <br />- Canyon City Project" and which shows the surface topographic <br />features and surface drainage systems in the vicinity of the <br />Dorchester No. 1 Mine. <br />4. Exhibit 3, attached, is entitled "Dorchester <br />No. 1 Mine - Soils Map" and which shows the mapping of soils <br />in the Dorchester No. 1 Mine vicinity. This map was pre- <br />pared by Mr. Dan Champion, a certified soils scientist, who <br />is employed by the U.S. Department of Agriculture, Agriculture <br />Research Service in Grand Junction, Colorado. <br />5. Exhibit 4, attached, is entitled "Dorchester <br />No. 1 - Vegetation Map." This m,ap was drawn with the assis- <br />tance of John G. Keenan, Ph.D., Assistant Professor and <br />Superintendent of Colorado State University's Western Colo- <br />rado Agricultural Research Center. <br />6. Exhibit 5, attached, is a letter dated Septem- <br />ber 23, 1980 to DCC from John G. Keenan, Ph.D., Assistant <br />Professor and Superintendent of Colorado State University's <br />Western Colorado Agricultural Research Center in Grand Junc- <br />tion, Colorado. This letter notes that less than one acre <br />occupied by the mine entrance could be perhaps classified as <br />an alluvial valley floor. The letter further states that the <br />feasibility of growing agronomic crops on this site does not <br />exist because the soil is shallow, somewhat rocky, there is <br />no natural occurring sub-irrigation and because there are no <br />irrigation water rights which could be developed. <br />7. Exhibit 6, attached, is a letter dated Septem- <br />ber 16, 1980 to DCC from Roy E. Roper, District Conservation- <br />ist, USDA's Soil Conservation Service in Canyon City, Colo- <br />rado. This letter describes Mr. Roper's opinion that the <br />
