III IIIIIIIIIIIII III <br />999 <br />STATE OF COLORADO <br />DIVISION OF MINERALS AND GEOLOGY <br />Department of Natural Resources <br />1313 Sherman 51., Room 215 <br />Denver, CO 80203 <br />Phone: 13031866-3567 <br />FAX: 1703) 832-8106 <br />January 19, 1994 <br />Mr. Ralph Lopez <br />Environmental Engineer <br />Basin Resources, Inc. <br />14300 Highway 12 <br />Weston, CO 81091 <br />RE: Permit Renewal No. 2, Golden Eagle Mine, Permit No. C-81-013, <br />New Elk Mine, Permit No. C-81-012, Basin Resources, Inc. <br />Dear Mr. Lopez: <br />This letter is to document the adequacy questions which were presented to <br />Basin Resources and Greystone Consulting during conversations on <br />January 11, 12, and 14, 1994. <br />A. Hydrology <br />1. Annual Hydrology Report <br />ov cow <br />~~~ <br />.. <br />~ r8]6 ~ <br />Roy Romer <br />Governor <br />Michael B. Long <br />Division Director <br />a. Station PRS-4 does not appear on page 7 of the AHR. Please <br />change page 7 of the AHR to show that PRS-4 has the same <br />monitoring requirements as PRS-1, 2, and 3. <br />b. Please include pond 5 in the monitoring requirements on <br />page 7 of the AHR. Pond 5 should appear for the same mine <br />discharge requirements as MDGE-l. The NPDES requirements <br />should remain the same. <br />c. Please include a note for greater clarity that PRS-3 is <br />GE-080 and that PRS-4 is NE-080. <br />d. Page 7 of the AHR shows that dissolved oxygen is required to <br />be measured for wells PAW-1 through PAW-7, ACAW-1, and <br />CCAW-l. I believe this is in error since dissolved oxygen <br />measurements are inappropriate for wells. Please change this <br />to exclude D.O. for well monitoring. <br />e. On page 7 of the AHR, should NE 003 be NE 033? <br />f. Please modify page 7 of the AHR to show that NE 006 is non <br />discharging and therefore does not require water monitoring. <br />
