Stipulation No. 10 <br /> Eliminate the words "proposed monitoring plan" from the data and maps <br /> submitted by Greystone in the approved TR-12 and incorporate this <br /> information into the correct sections in the permit document. <br /> Soils <br /> There are two primary soil series present on undisturbed sites within the <br /> present New Horizon Mine 1 permit area. The major soil is the Shavano <br /> series . It is a fine, loamy, mixed, frigid (ustic) Camborthid. Topsoil <br /> quality is good to an average depth of 18 inches on the gentler slopes and <br /> 12 inches on the steeper slopes . <br /> The Persayo series is found in conjunction with the Shavano soils on isolated <br /> ridges and steeper slopes in the permit area. The surface soils may range in <br /> texture from sandy clay loam to clay loam with variable content of shale and <br /> sandstone fragments . These steeply sloping, shallow soils are less suitable <br /> for topsoil than the Shavano series described previously. An average of six <br /> inches of fair topsoil may be obtained from the Persayo Series. <br /> There are three major soils types at the New Horizon Mine 2 area (see Soils <br /> Map of the permit application) : Progresso-Bond Complex, 2 to 15 percent <br /> slopes; Barx sandy loam, 1 to 4 percent slopes; and Haplaquolls , 1 to <br /> 3 percent slopes. <br /> The Progresso-Bond complex is comprised of 40 percent Progresso, 40 percent <br /> Bond, 10 percent Barx (see below) , 5 percent Travesilla, and 5 percent Bowdish <br /> series soils . The Progresso series is classified as a fine-loamy, mixed, <br /> mesic, Ustollic Haplargid. The Bond series is a loamy, mixed, mesic Lithic <br /> Ustollic Haplargid. The main difference between these two is the distance to <br /> bedrock; Bond soils are shallow ( 17 to 19 inches to bedrock) while Progresso <br /> soils are fairly deep (36 inches to bedrock) . This complex is found on gently <br /> to strongly sloping irrigated uplands over much of the New Horizon Mine 2 <br /> area. The soils are shallow to moderately deep, well drained sandy loamy <br /> formed in sandstone derived alluvium. Topsoil quality is good to an average <br /> depth of 2. 1 feet. <br /> The Barx soil is found in the southeast corner of the New Horizon Mine 2 <br /> permit area. It is classified as a fine-loamy, mixed , mesic Ustollic <br /> Haplargid. It is a deep, well drained sandy loam formed in sandstone derived <br /> alluvium. Part of this soil unit (about 15 acres) has been historically used <br /> for hay production, is irrigated with a dependable water supply, and has <br /> therefore been rated as prime farmland by the USDA - Soil Conservation <br /> Service. Special methods of soil handling for this orime farmland are <br /> discussed under "Description of the Operations and Reclamation Plan" below. <br /> Revegetation success standards and reclamation plant materials are discussed <br /> in Section B, Part X - Operations on Prime Farmlands . <br /> The ephemeral drainages of the New Horizon Mine 2 area contain three families <br /> of Haplaquoll soils ; Lithic, Lithic/Typic , and Typic Haplaquolls . The loamy, <br /> mixed, mesic , Lithic Haplaquolls are found in the upper reaches of the swales <br /> in the area and are the shallowest of the three series (bedrock at 11 <br /> inches) . Lithic/Typic Haplaquolls (coarse-loamy, mixed , mesic , moderately <br /> -9- <br />
