42.05 APPLICATION FOR PERMIT FOR SURFACE OR ONDERGROUND MINING ACTIVITIES -- <br />MINIMUM REQUIREMENTS FOR OPERATION AND RECLAMATION PLANS. <br />n <br />2.05.4 Reclamation Plan, <br />(2) (e) (Cont'd,) <br />• <br />(ii) Species and Amount Per Acre <br />Three planting mixtures will be utilized dur- <br />ing the reclamation process to achieve the two <br />post mining land uses (rangeland for livestock <br />and wildlife grazing, and cropland), The <br />rangeland planting mir. will be such that a <br />permanent vegetative cover of the same season- <br />al variety native to the Orchard Valley and <br />Orchard Valley West Mines will exist. Topsoil <br />piles which are projected to be inactive for <br />greater than five years would be seeded with <br />the permanent, rangeland planting mix. The <br />cropland planting mix will be such that the <br />agricultural productive capacity of the land <br />is eoual to pre-mining levels. The third mix <br />will be a temporary seeding mixture utilized <br />to stabilize soil or areas which will be tem- <br />porary during the life of Che mine, such as <br />temporary topsoil piles, and will be replaced <br />by either the rangeland planting mix or agri- <br />cultural planting mix, either during or at the <br />end of mining operations, <br />The following rangeland planting mix is in- <br />tended for future use at the Orchard Valley <br />and Orchard Valley Wesi Mines. As mentioned <br />in Section 2,05.10 (4), species diversity data <br />obtained from 3 reference areas in the summers <br />of 1981 and 1932 were used to develop a recla- <br />mation seed mixture to better reflect the naC- <br />ural conditions and post-mine land uses of the <br />Orchard Valley and Orchard Valley West Mines. <br />A variety of species are included on the list, <br />allowing C'dI to choose species, depending on <br />the price and availability of seed and tubl- <br />ings, Refer to the Vegetation Appendix in <br />Volume 9A for specific information on [he de- <br />velopnent of C'dI's reclamation seed mixture. <br />List of Species for Permanent Reclamation at <br />the Orchard Valley and Orchard Valley West <br />Mines is as follows: <br />Revised 10/12/86 <br />Revised 10!01187 <br />Revised 03/28/88 <br />69 <br />
