The utility company pursuing a compressor-station upgrade near Carbondale says the underground gas storage field it would serve is in good condition.
Black Hills Energy officials responded Wednesday to concerns from the Carbondale-based conservation group Wilderness Workshop that the addition of a new compressor at the compressor station could lead to leaks and other problems at the Wolf Creek storage field in the Thompson Divide area southwest of Glenwood Springs.
Wilderness Workshop notes that some of the wells date back to the 1960s. The group cites problems at the storage field including a 2009 fire at one well, what are considered historical leaks found in 2013, and emissions from surface equipment documented via an infrared video camera last summer. It says its concerns are heightened by the 2015 Aliso Canyon gas storage field leak in California that forced the evacuation of thousands of residents.
Wilderness Workshop has filed a notice of plans to appeal the Bureau of Land Management’s approval of a new compressor at the station. The upgrade would let Black Hills double the station’s daily compression capability during injection seasons to 14 million cubic feet of gas.
