The area southeast of the mill building, between the <br /> prospect pits on the White Cloud and Hercules patented lode mining claims, ~~ <br />~ <br /> are being used to stockpile topsoil. The topsoil will be protected from erosion ~ <br />~ <br /> and will not be disturbed by any Honing operations in this location.

The smaller <br /> trees and shrubs, and the branches and foliage from the larger trees, were <br />• incorporated in the wood fiber mulch that was applied to the surface of the <br /> stockpiled topsoil. <br />Re vegetation has proven to be the most effective reclamation method for sur- <br />face lands affected by mining and milling activities. If properly established, re <br />• vegetation will provide effective erosion control, contribute significantly to <br />water quality, result in aesthetic improvement, and return affected lands to a <br />ailvicultural usefulness. Therefore, the establishment of a permanent cover of <br />indigenous vegetation on the land surface affected by these milling operations <br />will be the primary objective of this reclamation plan. <br />~ Whereas the acne dumps are a mi7:ture of coarse and fine-grained quartz vein <br />material and waste rocks, the mill tailings will consist offine-grained sand and <br />silt that are predominately composed of gangue minerals. Because of the dif- <br />ferent physical and chemical characteristics between the mine dumps and the <br />mill tailings, the establishment of a diverse and effective vegetative cover on <br />these diasinular land surfaces will require separate approaches to re <br />~ vegetation. <br />' ' Heist of compacted, fine-grained, light-colored, siliceous, <br />~-aandyinaterial that have very few of'the essential chemical elements or physi- <br />cal properties needed for plant growth. Therefore, special reclamation techni- <br />~ ques will be employed to establish a permanent, self-sustaining, and diverse <br />cover of vegetation on the land surface affected by the impoundment of the mill <br />tailings. Because the tailings retention structure has three sloping aides and a <br />relatively flat surface, the species selection, site preparation, and planting <br />methods for these two areas will address their different physical characteris- <br />tics. The tailings impoundment area will be reclaimed in a manner that estab- <br />~ lishea a growth of pine trees and low ehnrbs along the starter dike, a cover of <br /> <br />
