This report covers an expanded water year of 18 months. <br /> The extended water year incorporates the change in the reporting period as approved in <br /> Minor Revision No. 34. Similar to previous reports, discussion of hydrologic data and <br /> comparison of these data with previous reporting periods are incorporated within the report. <br /> The AHR is prepared and submitted in accordance with Exhibit 25, Hydrologic Monitoring <br /> Plan, of the permit application. <br /> Energy Fuels Coal, Inc ("EFCI") operates the Southfield Mine located 8 miles south of <br /> Florence, Colorado as shown on Figure 1. Coal is produced by underground room and pillar <br /> mining methods. All run-of--mine coal is processed through the coal preparation plant to <br /> remove rock impurities and produce sized products. The mine and associated facilities were <br /> in active operating status during the reporting period, although the mine was idle from July 1, <br /> 1996 through November 14, 1996. <br /> Monitoring data and information compiled for the AHR were collected in compliance with the <br /> approved monitoring programs. In addition, data collected by the previous operator, <br /> Dorchester Coal Company (1979-1985) is included in data summary. Required monitoring <br /> data collected and presented in this AHR includes: quantity and quality of mine inflows; <br /> quantity and quality of discharges to streams; groundwater quality and levels; and stream flow <br /> quantity and quality. <br />
