reclaimed areas will have only received associated disturbances during mining activities. The associated disturbance relates to topsoil removal forthe location of roads, stockpiles, facilities, and regrading activities during reclamation. These areas were not flood irrigated prior to mining because of shallow soils, rock outcrops, and topography. Since these areas will remain basically unchanged in terms of topography, they will not be irrigated in the postmine land use except as noted forvegetation establishment. The establishment of a dryland pasture type is consistentwith both the pre- and postmining land uses in the area and best reflects that which is attainable under the expected site conditions and management potential. The production standard for the dryland pasture type for the New Horizon 2 (NH2) area will be based on a dryland reference area located at the Nucla Airport. This area was originally established in the summer of 2000 and augmented in 2005. The augmentation allows the reference area to be divided into two sections: one for rangeland and the otherfor dryland pasture. See Section 2.04.10 for more details. The Airport Dryland Reference (ADPR) area is shown in Attachment 2.05.4(2)(e) - 2 as well .The areas reclaimed to dryland pasture in the NH2 area will have acceptable herbaceous production and cover when the reclaimed area is not less than 90 percent of the reference area with 90 percent statistical confidence. The Airport Dryland Reference area is located within the fenced boundaries ofthe Nucla Airportand is protected from domestic livestock grazing. Wildlife (deer, elk) winter grazing will stil bel allowed, as is on the NH2 reclaimed land. If the airport authorities allow domestic grazing, then WFC has an agreement with the airport authorities to fence off the three plus acre reference area so the vegetation cover will not be compromised. Production yield (tons per acre per year) for Dryland Pasture will be determined by a random sampling method. This system will consist of: 1) Gridding the entire dryland pasture reclaimed field{s) being considered for bond release on a 50 foot by 50 foot pattern. The grid blocks will be sequentially numbered from the upper northwest comer to the lower southeast of each field. Only whole blocks will be numbered for the purpose of use in the random generator discussed below. Ifthere are separate fields, then the block numbers will be combined into one data base.
