r <br /> and Pinon soil series. The weighted average potential production for the <br /> Travesilla- Pinon complex is 625 pounds per acre per year. <br /> 3. The success standard requirements for species diversity, seasonal variety, <br /> and woody plant density on all three proposed end land use types will be <br /> waived since post-mining land uses will be pasture and hayland. <br /> The Division proposes to approve these standards. <br /> VIE. Post-mining Land Use <br /> A. The land use within the New Horizon Mine 2 is related to agriculture, grazing, <br /> and related support facilities. Approximately 85% of the proposed permit area <br /> is in irrigated agriculture. The remaining 15% is composed of sagebrush <br /> rangeland, abandoned orchards, farmsteads and facilities. With the exception <br /> of replanting the apple orchard, the mine plans to continue the same post <br /> mining land use. <br /> The Division is proposing to approve the existing post-mining land use of <br /> irrigated agriculture and grazing. (4.16.1) <br /> IX. Protection of Fish, Wildlife and Related Environmental Values <br /> A. Fish and wildlife habitat is a planned post-mining land use. The applicant has <br /> selected appropriate plant species and distributions to benefit fish and wildlife <br /> (4.18(5)(i))• <br /> X. Operations on Alluvial Valley Floors <br /> A. The Division has determined that there are no alluvial valley floors along <br /> Tuttle or Calamity Draws by definition. Geomorphically, these draws are <br /> located in uplands several miles northeast of the San Miguel River. The <br /> uplands are overlain by less than ten feet of unconsolidated material,which has <br /> been classified as aeolian and sheet wash material. (The depths of <br /> unconsolidated material are documented in Appendix 6-1.) These draws would <br /> only have intermittent flow if it were not for irrigation return flows and the <br /> areas are not naturally subirrigated. <br /> These areas are flood-irrigated by waters acquired from a headgate on the San <br /> Miguel River, located approximately 15 miles upstream. San Miguel River <br /> water quality (TDS of 180 mg/1) is far better than that found in either Tuttle <br /> (TDS of 1200 mg/1) or Calamity Draws (TDS of 1950 mg/1). Water from <br /> Tuttle or Calamity Draws could not be used for agriculture without very <br /> controlled management. <br /> 23 <br />
