The TR -65 application adds 2.83 acres to encompass the BB Detour Road. The addition changes <br />the permit area from 827.44 acres to 830.27 acres and affects the Slash M, LLC (Morgan) <br />property. <br />4.0 Description of Pre -Mine Land Use Areas <br />See Map 2.04.3 for the exact location of all of these areas. Detailed descriptions of the pre -mine <br />vegetation types are included in Section 2.04. 10 Vegetation Information. The entire permit area <br />is 830.27 acres. Of this total, 770.87 acres will be disturbed. <br />4.1 Cropland - Irrigated Orchards (ICO) This category includes a few abandoned fruit tree <br />orchards from decades ago. They were not well kept during initial permitting in 1987. <br />4.2 Cropland - Irrigated Alfalfa Hay (IC) These areas have some combination of grass and <br />alfalfa which are well-managed, irrigated consistently with application of fertilizer and <br />harvested. Alfalfa is the predominant plant. These lands have primarily prime farmland soils, as <br />determined by the NRCS in 2008. See discussion in this section on Prime Farmlands and prime <br />Farmland Soils. <br />4.3 Cropland - Irrigated Small Grain (ICSG) These areas were historically used for small <br />grain production. Within the permit area, soils where this type is delineated are generally shallow <br />and boggy, and not considered to have a high crop production potential. During the baseline <br />sampling year (1987) it was noted that the two ICSG areas were not tilled after harvest the <br />previous year and were allowed to volunteer barley, along with annual and perennial weeds. <br />4.4 Pastureland - Irrigated Hay (IPH) These areas have some combination of grass and alfalfa <br />which are not as well-managed as cropland, and not irrigated consistently but better managed <br />than irrigated pasture. IPH areas are generally baled, where irrigated pasture areas are not. <br />Vegetation cover is still very good, depending on the soils of the actual site. <br />4.5 Pastureland - Irrigated Grass (IP) These areas are primarily grasses but are not as well <br />managed as Pastureland - Irrigated Hay, have poorer soils and do not yield as much vegetation. <br />None of these areas are baled. <br />4.6 Pastureland - Irrigated Swales (IPSW) These areas are generally low lying areas which <br />drain irrigated fields around them. They are not directly irrigated but usually have substantial <br />water from the surrounding fields. They can have wetland plants and these areas are not managed <br />or baled. <br />June 2016 (TR -73) 2.04.3-5 <br />
