60,250 cubic yards in Phase VI were moved. A remaining 29,500 cubic yards of 808 soil type <br />• was left in place to allow further de-watering and it will be moved in the first quarter of 1996. <br />Tonsoil Thickness <br />The thickness of soil replaced during 1994 was verified by sampling. Sample sites for the New <br />Horizon 2 mining area were selected systematically utilizing a 467 foot by 467 foot grid pattern. <br />Sites at New Horizon 2 were surveyed and staked in the field using a Geodimeter 510 total <br />survey station. <br />A 2-314 inch bucket auger was used at each site [o excavate a pilot hole through the entire soil <br />strata. An abrupt boundary, defined by color and rock fragment content, typically occurred at <br />the soil/spoil interface. The replaced soil thickness was measured' through the pilot hole <br />immediately after encountering the spoil. <br />Soil thickness was determined at the 15 sample sites at NH2 shown on Exhibit 95.4. Soil <br />thickness information for each sample site is located on the map. <br />New Horizon 2 has many different soil thickness requirements as shown on Exhibit 95.6, which <br />is 2.05.4-4 from the current permit. <br />Topsoil ualit_v <br />At NH2 15 topsoil samples have been taken and sent to CSU for analysis as shown in <br />Attachment 95.B. All sample show good fertility and fertilization amounts have been based off <br />• these tests. <br />Topsoil Salvage and Storaee <br />All suitable soil has been salvaged ahead of mining at New Horizon 2. Approximately 104,900 <br />(LIFT 2), 12,900 (LIFT 1), and 36,000 (MIXED) cubic yards of soil are stored in stockpiles at <br />the end of 1995. The soils were separately stockpiled by soil types as specified by our permit. <br />Cover Cron <br />All topsoil stockpiles have been planted with the approved cover crop seed mixture. Only one <br />stockpile was seeded in 1995. <br />Weed and Pest Control Activities <br />Weed control was carried out in [he summer and fall months of 1995. Target species included <br />Russian Knapweed, Canada Thistle, Sun Flower and Field Bindweed. Spot sparing was done <br />on 194 acres at NH2, see Exhibit 95.3. The treated sites were small and random. To small to <br />plot on a rnap accurately. A log was kept as shown on Attachment 95.C. <br />Fertilization <br />A total of 78.36 acres were fertilized at NH1 and 36.2 acres at NH2. A mixture of 18% <br />nitrogen, 46% phosphate and 0% potassium was spread a various rates according to Topsoil need <br />and projected irrigation. <br />2 <br />
