Project Description

Rocky Mountain Natural Gas (RMNG), a subsidiary of SourceGas LLC, is proposing to upgrade a segment of the Rifle to Avon natural gas pipeline that serves natural gas customers in Garfield, Eagle, Pitkin, and Summit Counties. The segment of pipeline is located within the vicinity of the Eagle Ranch Subdivision south of Eagle, CO and is currently in a Class 3 area as defined by the Pipeline Hazardous Material Safety Administration (PHMSA) and requires an upgraded pipeline wall thickness to maintain the maximum allowable operating pressure (MAOP) and/or relocation away from densely populated areas.

Rocky Mountain Natural Gas is proposing 3 alternatives to complete the necessary pipeline upgrade. Alternative 1 involves replacing the existing pipeline segment within the existing easement through the Class 3 Eagle Ranch Subdivision. Alternatives 2 and 3 involve rerouting the pipeline south of the Class 3 area through BLM land and the Town of Eagle Open Space land. The proposed pipeline upgrade would be approximately 3.4 to 4.6-miles long depending on the alternative selected. SourceGas is requesting a 50-foot permanent ROW on BLM and easement on the Town of Eagle Open Space, plus a 25-foot wide temporary use permit to provide for construction access, equipment operation, and material handling. SourceGas has also requested three 1-acre temporary work areas, for staging equipment and materials. The temporary work areas would be located in Hernage Creek Gulch, Third Gulch, and Hardscrabble Mountain Road. SourceGas is proposing to begin work early summer 2016.

Plant and cultural resource surveys are currently being completed. When the surveys are completed and analyzed, RMNG will submit a final Proposed Action.

Pending a final Proposed Action, please see the Project Proposal and Map on the Documents and Maps links in the navigation pane on this website for additional details. The Project Proposal is expected to be very close to the final Proposed Action and is being posted now to aid the public in understanding the project and for providing comments to the BLM.

The project is located on Bureau of Land management (BLM) – administered lands and Town of Eagle Open Space lands in Eagle County, Colorado. The project area is located south of Eagle in the vicinity of the Eagle Ranch Subdivision.

The legal description for the project is as follows: Sixth Principal Meridian, Colorado, T. 5 S., R. 84 W., Sections 9, 14 - 17, and 20 - 22.
