O. Box 14000 <br />Grand Junction, CO 81502 <br />RE: JD-9 URANIUM MINE -Permit No. M-77-306 <br />Dear Mr. Cotter: <br />/~.. <br />~~~~~ <br />DEPARTMENT OF <br />NATURAL <br />RESOURCES <br />Roy Ramer <br />Govc~nor <br />dames 5. Lochhead <br />Exec W ive Dueaor <br />ntichael B Lnnti <br />Divnion Diream <br />I inspected the JD-9 Mine on February 1, 1996, and found no visible evidence of subsidence at or <br />near the mine facilities. However, the ground was covered with at least 12 inches of snow. As <br />a result, the Division will make an attempt to re-inspect later this spring during more favorable <br />weather conditions. It would be helpful to have a sketch of the particular area in question where <br />there is believed to be subsidence from the JD-9 Mine. <br />Also, there was a discharge of approximately 5 gallons per minute of treated mine water from an <br />airshaft, near the airstrip. I have asked the operator for verification of an approved water discharge <br />permit from the Colorado Department of Health regarding this matter. <br />Please call either me or Jim Stevens at (303 866-3567, if we can be of further assistance. <br />Sincerely, <br />Thomas A. Schreiner <br />Environmental Protection Specialist <br />cc: Jim Stevens, DMG <br />M:\oa.VD-9.w <br />
