IRI, a number of Irrigated Pasture areas and Irrigated Pasture Swales were identified on the Morgan property. Subsequent discussions with the Morgans have taken place where they believe that over the years, the historic use of these areas has been Irrigated Cropland. For this reason, the Irrigated Pasture areas have been re- designated as Irrigated Cropland for the Permit Revision 06. The San Miguel Power property, east of 2700 Road has been both irrigated and used as dryland in the past. Although San Miguel does not have ditch rights, they are supplied water by WFC from Calamity Draw. For this reason, the land has been classified as Irrigated Pasture (IP). There are 5 types of Rangeland - Sagebrush (SG), Sagebrush 1 (SG -1) and Sagebrush 2 (SG -2), Floodplain and Deciduous Trees. Roads (R) are classified as Commercial use and Farmsteads and associated open space disturbances are now classified as Residential use. Existing Disturbed lands have now been called Residential - Open Space Disturbed Areas. No boundaries of these land use areas have been changed, only the classification categories to comply with Rule 1.04. For the 2009 Permit Revision, a slight boundary adjustment due to more accurate surveying has changed the permit boundary from 823.56 acres to 827.44 acres. The changes all occur on the extreme west edge of the permit area on the Morgan property and the WFC property. 4.0 Description of Pre -Mine Land Use Areas See Map 2.04.3 for the exact location of all of these areas. Detailed descriptions of the pre -mine vegetation types are included in Section 2.04.10 Vegetation Information. The entire permit area is 827.44 acres. Of this total, 764.06 acres will be disturbed. 4.1 Cropland - Irrigated Orchards QCO) This category includes a few abandoned fruit tree orchards from decades ago. They were not in well kept condition during the initial permitting in 1987. 4.2 Cropland - Irrigated Alfalfa Hay (IQ These areas have some combination of grass and alfalfa which are well- managed, irrigated consistently with application of fertilizer and harvested. Alfalfa is the predominant plant. These lands have primarily prime farmland soils, as determined by the NRCS in 2008. See discussion in this section on Prime Farmlands and prime Farmland Soils. 4.3 Cropland - Irrigated Small Grain (ICSG) These areas were historically used for small grain production. Within the permit area, soils where this type is delineated are generally shallow and (Revised July 2010) 2.04.3 -8
