N III IIIIIIIIIIIIIIII ~ <br />SUMMARY -NORTH OF DOUGLAS PASS <br />This application amends an existing 110 permit, M81-043. It increases the area from <br />7.12 acres to 9.59 acres. The present pit excavation and disturbed azea is approaching the <br />maximum 7.12 acres allowed by the existing 110 permit. The increase in acreage will allow for <br />continued use of the pit for 3(1 years at past production rates. Also, it will provides the acreage <br />required to reclaim the existing slope to an average slope of 1:1, more consistent with the <br />existing terrain. The existing pit excavation consists of a very steep cut about 100 feet in height. <br />The shale material in this pit is layered and no[ extremely hazd. Therefore, the most <br />economical method of excavation is ripping with dozers. The shale in this pit makes good road <br />subgrade and fill material but is not suitable for quality aggregates. Therefore, crushed <br />aggregates or hot mixed bituminous paving will not be produced. Blasting is not anticipated. <br />This pit provides fill material for maintaining the upper one half of Highway 139. <br />Normal maintenance of Highway 139 requires small quantities, probably about 1,000 CY per <br />yeaz. Use can be much higher if the Douglas Pass slide moves, requiring reconstruction of miles <br />of road. <br />The pit is located on Bureau of Land Management property and has been mined since <br />1966. It is located west of Highway 139 at milepost 47. <br />
