Both of these mines have employed <br />surface mine techniques to extract coal from the Wadge (Energy Mine No. <br />i) and Fish Creek (Energy Fiine No. 2) coal seams. These mines have <br />been in continuous operation since their respective star*_-up dates, <br />although mining at Energy I+,ine No. 2 will terminate by the end cf <br />1979. The amount of coal removed to date at these mines is set forth <br />in Table 1, Historical Production Rates. <br />~~s explained in Section 779.19 pages 779-107 and 779-107(a), vegetation <br />(mapping was revised in 1988 based on 1954 and 1962 aerial photographs. <br />areas previously mapped as mined land or revegetated were eliminated <br />and original vegetation types expanded to cover those areas.

Table 81, Land Use <br />Capabilities and Cropland Potentials within the Proposed Energy Fuels <br />Corporation Permit Area spews this information. Characteristics cf <br />these specific capabilities classes can be described as follov:s: <br />Class 1V. Soils in this class are currently being used for croplanc <br />C within cropland fields C4 and C5.
