• drainage or erosion control measures discussed previously. In addition, the haul road <br />constructed along the steep eastern slope of the Revision 1 Area will be reclaimed. A <br />terrace will be constructed from the intersection of Terrace No. 1 and the haul road around <br />the slope to the west. <br />A physical examination of core samples from drill holes showed that no material exists in <br />the overburden or interburden that would make them detrimental as a soil substitute or <br />plant medium. Also, no toxic or acid-forming materials have been encountered in <br />overburden and interburden sampling in the current mine area. No adverse impacts to the <br />water or soils resource is anticipated as a result of surface raining operations. <br />Sealin og f Exploration and Mine Holes <br />The measures to be used to plug, case or manage exploration holes other than bore holes, <br />wells and other opening within the permit area will include filling the hole or opening with <br />cuttings or inert material to the surface, cementing those holes which flow or might flow as <br />a result of any possible artesian conditions, and casing or cementing any holes which <br />penetrate the aquifer with significant groundwater quality and quantity. <br />Those holes which remain open for use as a water supply well or for use as groundwater <br />monitoring sources are completed with casing or piezometers at a sufficient height above the <br />ground surface to prevent drainage of surface water of introduction of foreign material into <br />• the well. All such monitoring points are equipped with caps to prevent the introduction of <br />objects other than groundwater monitoring equipment. Water wells utilized as ground water <br />monitoring consist of domestic deep wells and shallow alluvial valley floor wells. The <br />domestic wells will obviously remain intact upon the cessation of operations while the <br />shallow wells will be removed. If actual removal of the wells is not possible, the cases will <br />be backfilled with bentonite and the well heads will be removed. <br />Reve etg ation <br />After soil replacement has been completed, the area will be seeded. This will be done using <br />a seed drill, hand broadcaster, by hydroseeding, or by the use of other appropriate <br />mechanized methods (e.g., steep slope seeder). Where hand broadcasting is used, the site <br />will be raked or harrowed following seeding in order to cover the seed. <br />Soil amendments will be determined by a nutrient analysis (i.e. N, P, K, pH, Ca, Mg, and <br />Na) of the stored soil material just prior to distribution of these materials on the graded <br />areas. Fertilizer will be applied only in accordance with the results of the nutrient analysis <br />tests and after it has been determined that vegetative success cannot otherwise be achieved <br />without the use of such fertilizer amendments. Fertilizer will be applied by broadcasting and <br />raking or by post-emergence broad-cast techniques. <br />• 2.05-5 <br />
