Springs G -26A and CR -12 and Lone Pine Gulch are relatively close to the <br />proposed mining area. Based upon monitoring data collected for the annual hydrologic reports, the <br />mine has not had a noticeable affect on the above mentioned springs. <br />(b)(iv) The hydrological monitoring plan is presented in Section 2.04.7(1)(v) and 4.05.13. <br />Monitoring and reporting water data is discussed under Section 4.05.13. Additional information <br />• concerning hydrologic impacts and mitigation measures are set forth in Section 2.04.7. <br />• 2.05 -55 c i i Rev. 7/98 <br />
