• <br /> DESIGN ANALYSIS AND CRITERIA <br /> The proposed mining slopes were analyzed using the XSTABL v5.105a computer <br /> program. XSTABL was designed to analyze the slope stability of earth embankments <br /> subjected to several critical situations that may occur during the life of the embankment. <br /> For this project, four cases were identified as critical during the mining operation. Static <br /> and pseudo-static conditions were analyzed in each case. <br /> Pseudo-static peak acceleration factors were taken from USGS information for the <br /> western United States. The 2% probability of exceedance in 50 years (the most <br /> conservative) was used. <br /> Surface loading equivalent to an HS 20 highway load was applied adjacent to each area <br /> to simulate heavy equipment loading that could be present at that location for <br /> maintenance or construction activities. <br /> All mining side slopes will be 3H:1V. <br /> Case 1 — Right-of-Way and Electric Line on West Side of Northwest Pit. The <br /> mining operation is adjacent to a right-of-way with an electric line to the west. <br /> The proposed setback for mining is 50 feet from the right-of-way. The mining <br /> depth was assumed to be 26 feet. <br /> Case 2— Right-of-Way and Electric Line on North Side of Northwest Pit. The <br /> mining operation is adjacent to a right of way with a road and electric line to the <br /> north. The proposed setback for mining is 50 feet from the right-of-way. The <br /> mining depth was assumed to be 26 feet. <br /> Case 3 — Well Head on North Side of Northwest Pit. The mining operation is <br /> adjacent to a well head to the north. The proposed setback for mining is 150 feet <br /> from the well head. The mining depth was assumed to be 26 feet. <br /> Case 4 — Gas Easement and Gas line on South Side of Northwest Pit and <br /> North Side of Southwest Pit. The mining operation is adjacent to a gas line <br /> easement and gas line. The proposed setback for mining is 50 feet from the <br /> easement. The mining depth was assumed to be 26 feet. <br /> Case 5 — Right-of-Way and Electric Line on East Side of Southwest Pit. The <br /> mining operation is adjacent to a right-of-way and electric line to the east. The <br /> proposed setback for mining is 50 feet from the right-of-way. The mining depth <br /> was assumed to be 28 feet. <br /> Case 6 — Gas Line on East Side of Northeast Pit. The mining operation is <br /> adjacent to a gas line to the east. The proposed setback for mining is 50 feet <br /> from the gas line. The mining depth was assumed to be 27 feet. <br /> Lupton Meadows Sand and Gravel <br /> la Consulting, Inc. upton Meadows Sand and Gravel Mine <br /> gfC.
