<br />Harry Itanney - 2 - June 11, 1999 <br />Bramiers Draw is the major drainage feature to the west of the permit area. Because the permit area <br />slopes to the east, Bramiers Draw will only receive a minor amount of drainage from the permit area. <br />Flow from Bramiers Draw would discharge directly into the San Miguel River. There has not been <br />a recorded flow in Braimers draw since monitoring began in 1991. <br />Naturita Creek is the receiving stream for the drainage from the central and eastern portion of the <br />permit azea This creek typically flows year round. Because of the distance between the mine stie and <br />the Creek, it is highly unlikely the mine site could have any impact on the quality or quantity of flow <br />in Naturita Creek. <br />Six springs are located adjacent to the mining area. SP-l, located in Long Draw, has not had a <br />recorded flow since the second quarter of 1991. SP-2, located in Section 33 Creek, has not had a <br />recorded flow since the second quarter of 1991. SP-3, located in Bramiers Draw, has not had any <br />recorded flow in ten years of monitoring data (1989 - 1998). SP-4 and SP-5, located in Bramiers <br />Draw, have not had any recorded flow in ten years of monitoring data (1989 - 1998). SP-6 also located <br />in Bramiers Draw, has recorded flow during two calendar quarters (1991 - 1998). <br />Four alluvial wells, AW-4 & AW-5, AW-6 & AW-7 were installed to determine if the quality of water <br />in the alluvium near the alluvial valley floor near the San Miguel River is impacted by the mining <br />operation. Two wells are located along Bramiers Draw AW-4 & AW-5 and two are installed along <br />Naturita Creek AW-6 & AW-7. The wells in each drainage, are located up gradient and down gradient <br />of the Reed Chatfield irrigation ditch. There is no evidence the mining operation has impacted the <br />quality of water in the alluvium. The historic lack of flow in Bramiers Draw provides further evidence <br />the mining operation could not and will not impact the quality of water in the alluvium. <br />Two bedrock wells are located adjacent to the mining area and one well is located within the permit <br />area BW-1, located east of the mining area has contained measurable quantities of water during most <br />monitoring events. BW-2 is located in the northwest corner of the permit area and has been recorded <br />as dry since 1991. BW-3 is located southeast ofthe mining area. BW-1 and BW-3 are so far from the <br />mine site that it would be highly unlikely mining activities could impact the wells. <br />Enclosed is an application for a technical revision which requests approval to cease hydrologic <br />monitoring. Revised page 2.05-35 comprises this technical revision application: <br />Please call if you have any questions. <br />Sincerely, <br />f~~ <br />J. E.
