<br />Sinclair Pipeline Company -Gas Pipeline <br />Starting from the south, the Sinclav Pipeline Company has an underground gas pipeline along <br />the property line between Parcels C-1 and C-2, turns west along the south side of 100'" <br />Avenue, turns northwest under the Fulton Ditch, crosses southwest corner of Parcel B and <br />the S. Platte River, and then continues north along the west side of the S. Platte River on <br />Parcels D-2 and D-3 to 104' Avenue. The Slope Stability Analysis determined that a setback <br />of 35' is sufficient to ensure that a structure such as a pipeline would not be impacted by <br />mining, but per comments from the DMG the mining setback will be 200' from the <br />pipeline except by agreement with Sinclair or acceptance by DMG of a revised Slope <br />Stability Analysis proposing a lesser setback than 200'. /tem #7 - Sorenson's comment <br />City of Northglenn and CCWCD -Non-Pressurized Water Discharge Pipelines <br />Starting from the north side of Fulton Ditch, the City of Northglenn has anon-pressurized <br />underground water discharge pipeline from the Fulton Ditch to the S. Platte River. A second <br />parallel similar pipeline will also be installed by the Central Colorado Water Conservancy <br />District (CCWCD) in the future, between the City ofNorthglenn's pipeline and the Sinclair <br />gas pipeline. The Slope Stability Analysis determined that a setback of 35' is sufficient to <br />ensure that a structure such as a pipeline would not be impacted by mining. Prior to mining <br />being undertaken, the exact location ofthe City of Northglenn's pipeline shall be staked in the <br />field to ensure this setback is followed. As the future CCWCD will be located on the non- <br />mining side of the existing City of Northglenn's non-pressured water pipeline, the nearest <br />mining will be from this future pipeline is 75'+. <br />l04"' Avenue (SH#44-CDOT), Mckay Road and 100"' Avenue (Adams County), and <br />Miscellaneous Utilities in Above Roads -United Power, U.S. West, and Public Service <br />Company of Colorado (PSCo.) <br />The above roads surround and abut major portions of the permit area. Within the right-of- <br />way of these roads are above and underground utility lines owned by United Power, U.S. <br />West, and Public Service Company of Colorado. The Slope Stability Analysis determined that <br />a setback of 35' is sufficient to ensure that these right-of--ways and structures within these <br />rights-of--ways would not be impacted by mining. In most cases, the location of [he utilities <br />within the right-of--way in relation to the minimum setback of 35' from the edge of the right- <br />of-way will lead to a setback of much greater than the minimum 35'. United Power has <br />written that they have no objection to the proposed setback from their power poles in <br />the abutting right-of--way, and the PSCo, agreement on the slurry wall installation and <br />setback from the PSCo. towers will also cover the other power poles in abutting right- <br />of-way. Therfore, per comments from the DMG the mining setback will be 200' from <br />PSCo. towers and power line poles, except by agreement with PSCo. acceptable to <br />DMG or acceptance by DMG of a revised Slope Stability Analysis proposing a lesser <br />setback than 200'.
