collected from these sites is extensive, spans several decades, and should be sufficient for <br />providing baseline surface water information, including continuous flow data during <br />earlier years on upper Grassy Creek, for evaluating the potential for subsidence from <br />underground mining operations. <br />Other Hydrology Baseline Data <br />A spring and seep field inventory will be conducted along the proposed haulroad and <br />mine access routes and in the vicinity of the portal during May or June of 2008. Maps <br />and State Engineer Office records will be consulted prior to the survey to identify any <br />existing spring or seep that may be affected. If a significant spring or seep is found <br />during the inspection, the site will be mapped and flow measurements, field water quality <br />parameters and water samples will be collected. Monitoring will be continued on a <br />monthly basis for the duration of 2008 until weather prevents access. Monthly <br />monitoring of these sites will continue during the spring of 2009 until one year of data is <br />collected. <br />An inventory of existing water resources within the proposed mining area and within one <br />mile of the affected area boundary during the baseline period will be conducted by <br />reviewing State Engineer Office maps and records in order to document locations and <br />determine usage such as well yields. <br />• <br />1�1 <br />P, <br />
