Uncompahgre Ave. <br />Montrose, CO 81401 <br />(303) 249-8407 <br />' United Companies <br />P.O. Box 3609 <br />'~ Grand Junction, CO 81502 <br />Attention: Paul McGehee <br />The soil located on the property your company intends to mine is a <br />Vernal clay loam. It is a deep, well drained soil formed on <br />stream/river terraces. The soil is at least 60 inches deep and <br />t moderately fine textured. These soils are not highly susceptible to <br />erosion and it's structure is fairly stable. The fields are presently <br />irrigated and support a mixture of grasses and legumes. The Vernal <br />clay loam is considered prime farmland as identified in the Important <br />Farmland Inventory of Colorado, 1982. <br />' It is my understanding after our conversation that your company <br />intends to mine the area to at least a 25-30' depth. With this in <br />mind, our recommendation for reclamation would include the following: <br />' All soil overburden should be stockpiled and replaced over the <br />mined area once the mining is completed. Since there will be no <br />border around the edges of this property, it is our recommendation <br />that at least a 3:1 slope be maintained or replaced next to adjacent <br />landowners. This should ensure that no sloughing or slumping takes <br />place, and the slopes will be easier to reseed. <br />' Reseeding of the area should begin once the topsoil has been <br />spread back over the area. Seeding should be done in the late fall, <br />but before the ground is frozen. A seed mix of the following species <br />' should be drilled: <br />Nezpar - Indian ricegrass - 40% 7 lbs/acre <br />' Sodar - Streambank wheatgrass - 20% 3 lbs/acre <br />Paiute - Orchard grass - 10% 1 lb /acre <br />Galleta - 20% 3 lbs/acre <br /> <br />1 <br /> <br /> <br />t <br />A mulch should be applied over the seeding. Straw would be ok, if it <br />was crimped in. There is no guarantee that the seeding will take as <br />this area only receives around 9 inches of precipitation a year. More <br />than one seeding may be needed to insure a stand of grass. If you <br />have any questions concernipg this report, feel free to contact the <br />Soil Conservation Service at 249-8407 in Montrose. <br />Respectfully, \` <br />^~~et1 ~J ~ v <br />Fred Miller <br />Shawano Soil ~ ation <br />District President <br /> <br />
