correspond to soils mapping units 77PIN and 78 PIN. Most of the Wetland Land Use <br />areas correspond to the Aquolls and heavily irrigated soils types. <br />All of the Intensively Managed Irrigated Pasture Areas possess soils which are classified <br />as being fine - loamy, mixed, mesic Ustollic Haplargids. The Irrigated Pasture soils are <br />classified as consisting mostly of fine- loamy, mixed, mesic Ustollic Haplargids. Most of <br />the Dryland Pasture areas correspond to soils which are classified as consisting of loamy, <br />mixed, mesic Lithic Ustollic Calciorthids. The Sagebrush or Grazing land areas consist <br />mostly of loamy, mixed, mesic, Lithic Ustollic Calciorthids. The Wetland areas <br />correspond mostly to soils which are classified as Aquolls. <br />The topsoil materials within the NHN Mine disturbance area which contain the highest <br />suitable rankings for use in reclamation consist of soils mapping units 81 PRO and 82 <br />PRO. Soil mapping units 71NYS, Nyswonger silty clay loam, 1 to 4 percent slopes is <br />classified by the NRCS to be a "prime farmland ", if it is cropped and irrigated, but as <br />documented in Section 2.04.12, there is no historic evidence of these soils ever being <br />irrigated or cropped and hence they do not meet the definition of a "prime farmland" soil. <br />Generally, those soils having a very high percentage of coarse fragments (greater than 20 <br />percent by volume), very shallow bedrock (0 to 10 inches), and shallow ground water <br />(less than 1 to 2 feet), have little suitable topsoil to be salvaged. No topsoil is available to <br />be salvaged from existing roads, ponds, ditches, residences, or farmyards. <br />The pre -mine soil survey, presented in Section 2.04.9 and the prime farmland soil <br />investigation conducted in response to Section 2.04.12 did not define any soil within the <br />proposed NHN permit boundary as being "prime farmland ". <br />The soil suitability criteria to be used at the proposed NI-IN Mine are presented in Table <br />2.05.4(2(d) -1. <br />Section 2.05.4(2)(d) Page 9 January 2012 <br />
