Pipeline replacement proposed up Four Mile

Black Hills Energy swapping out older pipes at existing natural gas storage facility

COMMUNITY NOTICE
June 19, 2025

Black Hills Energy is proposing to replace existing 3- and 4-inch natural gas pipe in the Four Mile area with new 10-inch pipeline. The proposed work, which is slated for summers of 2026 and ‘27, is in the area near the Wolf Creek Underground Storage Unit in Pitkin County and the haul route accessing the site is Four Mile Road (County Road 117) near Glenwood Springs.

Black Hills Energy is planning to move the 10-inch pipe to its company-owned property near Four Mile Park Monday through Wednesday, June 23-25. A total of eight semi-truck loads of pipes will be delivered over those three days. The proposed project, which is awaiting completion of the U.S. Forest Service’s National Environment Policy Act (NEPA) process, neither increases reservoir capacity at the Wolf Creek Underground Storage Unit, nor is related to any natural gas production.

White River National Forest District Ranger and acting Engineering Staff Officer Kevin Warner is presenting the pipeline project, as well as the details of an upcoming Forest Service timber sale in the same area, to the Board of County Commissioners in a work session on Tuesday, July 8, at the Garfield County Administration Building in Glenwood Springs.
