Marr Mine - 2007 Annual Hydrology Report May 2007 <br />2.0 !IMONITORING AND ANALYSES <br />Water monitoring activities during the 2007 water year (Oct. 2006 through Sept. 2007) were <br />generally based on the revised hydrologic monitoring schedule as approved in Technical Revision <br />No. 19 (TR-19), Table 61 (revised August 1999). TR-19 included a proposal to reduce monitoring <br />activities. In response letters dated January 20, 1999 and October 1, 1999, the DRMS accepted <br />the following modifications to that monitoring schedule: <br />Surface water sites 300, 306, 314, 316, 317, 318, 322, and 327, and ground water <br />sites AP-3 and AP-4 at the Loadout, have been dropped from monitoring. Monitoring <br />of the ground water wells in the Sudduth Coal Seam (79-61) and the overburden (79- <br />1, 79-2, and 79-3) is not required until the last two years preceding final bond release <br />(2005 and 2006 water years). <br />Sampling during the 2007 water year was completed in accordance with the permit requirements <br />according to the general schedule as listed below. All field data and sample collection for the <br />water year was conducted under the direction of James Mossman of Kerr. All sample analyses <br />were performed by ACZ Laboratories, Inc. of Steamboat Springs, Colorado. <br />Alluvial/Spoil Groundwater - Quarterly Monitoring (except winter) - AO-2A, SP-01, AP-1 <br />and AP-2 (3 events completed) <br />Bedrock Groundwater - Semi-annual Monitoring - 79-1, 79-2, 79-3, and 79-61 (3 events <br />completed in 2007) <br />Surface water - Monitored weekly from March through June, then monthly through <br />September. <br />This report discusses the groundwater and surface water monitoring activities and summarizes the <br />data collected during the 2007 water year in the following sections: <br />• Section 3.0 - Mine Area Groundwater (Water Table) <br />• Section 4.0 - Mine Area Alluvial Groundwater <br />• Section 5.0 - Loadout Area Alluvial Groundwater <br />• Section 6.0 - Mine Area Surface Water <br />• Section 7.0 - Loadout Area Surface Water <br />• Section 8.0 - Well Inspection <br />• Section 9.0 - Future Monitoring <br />Field and laboratory data are included in Appendices A through D. Locations of the monitoring <br />stations and wells are shown on Map 1, Mine Area Monitoring Stations, and Map 2, Loadout Area <br />Monitoring Stations. <br />6371/2007/2007 hydrology rpt Page 2
