assumed to be 60 feet in this area based on bore log information in the <br /> geotechnical report. The minimum mining setback was set 150 feet from the river <br /> bank. <br /> Case 4 — Gas Line Easement. The mining operation is adjacent to a pipeline <br /> easement along the East of the mining site. The mining depth was assumed to <br /> be 85 feet in this area based on bore log information in the geotechnical report. <br /> The proposed mining setback was set 50 feet from the pipeline easement. <br /> Case 5 — Gas Line Easement. The mining operation is adjacent to a pipeline <br /> easement along the East side of the mining site. The mining depth was assumed <br /> to be 100 feet in this area based on bore log information in the geotechnical <br /> report. The proposed mining setback was set 50 feet from the pipeline easement. <br /> Case 6 — Weld County Parkway Right-of-Way. The mining operation is <br /> adjacent to the Weld County Parkway right-of-way to the west.

The mining operation is <br /> adjacent to an irrigation ditch and pipeline easement along the South side of the <br /> pit. The mining depth was assumed to be 75 feet in this area based on bore log <br /> information in the geotechnical reports. The proposed mining setback was set 50 <br /> feet from the irrigation ditch. <br /> Case 9 — Power Line. The mining operation is adjacent to an overhead electric <br /> line along the South side of the pit. The mining depth was assumed to be 100 <br /> feet in this area based on bore log information in the geotechnical reports. The <br /> proposed mining setback was set 60 feet from the power line. <br /> Case 10 — Irrigation Ditch. The mining operation is adjacent to an irrigation <br /> ditch along the South side of the pit. The mining depth was assumed to be 100 <br /> feet in this area based on bore log information in the geotechnical reports. The <br /> proposed mining setback was set 60 feet from the ditch. <br /> Case 11 — Gas Line Easement. The mining operation is adjacent to a pipeline <br /> easement along the South side of the pit. The mining depth was assumed to be <br /> 90 feet in this area based on bore log information in the geotechnical reports. <br /> The proposed mining setback was set 60 feet from the pipeline easement. <br /> J-2 Contracting Company-DPG Pit <br /> Slop <br /> J&T Consulting, Inc. e Stabil�tyAPage/3 <br />
