March 2004 Ken Coal Company * 2003 Annna! Hydmlapy Aepore * CO Permit No. C-80-006 I Page 2 ' 2.0 MONITORING AND ANALYSES ' Water monitoring activities during the 2003 water year (Oct. 2002 through Sept. 2003) were generally based on the revised hydrologic monitoring schedule as approved in Technical Revision No. 19 ('I'R- 19), Table 61 (revised August 1999). TR-19 included a proposal to reduce monitoring activities. In response, letters dated January 20, 1999 and October 1, 1999, the State of Colorado Division of ' Minerals and Geology (DMG) accepted the following modifications to the existing monitoring schedule: Surface water sites 300, 306, 314, 316, 317, 318, 322, and 327, and ground water sites AP-3 and AP-4 at the loadout, have been dropped from monitoring. Monitoring of the ground water wells in the Sudduth Coal Seam (79-61) and the overburden (79-], 79-2, and 79-3) is not required until the last two years preceding final bond release. All field data and sample collection for the 2003 water year was conducted under the direction of James Mossman of Kerr Coal Company. All sample analyses were performed by ACZ Laboratories, Inc. of Steamboat Springs, Colorado. This report discusses the groundwater and surface water monitoring activities and summarizes the data collected during the 2003 water year in the following sections: • Section 3 -Mine Area Groundwater (lY/ater-Table) • Section 4 -Mine Area Alluvial Groundwater • Section 5 - LoadoutArea Alluvial Groundwater • Section 6 -Mine Area Surface Water • Section 7 - LaadautArea Surface IP/ater • Section 8 - Welllnrpection • Section 9 -Future Monitoring Field and laboratory data aze included in Appendices A through C.
