LOng <br />Division Director <br />RE: Adequacy Review, TR-44 <br />Hydrologic Monitoring Reduction, Golden Eagle Mine, #C-81-013 <br />Dear Ms. Begej: <br />The Division has completed review of Technical Revision (TR-44) for <br />the Golden Eagle mine. <br />1. Map 7B was submitted with the revised materials. Why does <br />this map only show a portion of the proposed monitoring sites? <br />Sites not shown include GEM-2 GEM-3, all NM sites and SF-2. <br />It would seem more appropriate to indicate all monitoring <br />sites on one map to avoid confusion. <br />2. Also, on map 7B, GEM-1 is shown ae an old ventilation shaft <br />site. The Division is aware of some 30 sites which will be <br />converted to an industrial land-use for gas extraction from <br />the mine. Will there continue to be access through a borehole <br />or other opening at this site, as well as the other GEM sites, <br />to conduct water sampling? <br />3. Related to question #1, text on page 2.05-47e indicates Map 7 <br />presents the current monitoring stations. This should be <br />corrected based on the final resolution of the map issue. <br />Please submit responses to the above questions, assuming a Division <br />decision deadline of April 5, 1997. If you have questions, please <br />call me. <br />Sin ely,% y <br />~~~~~ <br />Ke A. or am <br />Environmental Protection Specialist <br />CC: Dan Hernandez, DMG <br />
