Ownership
The Skyline Complex was owned by Arch Coal,[5] as part of Arch Coal's western bituminous mining region, which sold 20.6 million tons of coal in 2008.[6]
In June 2013 Canyon Fuel Co. was sold by Arch Coal Inc. for US$435 million to Bowie Resources, a mining firm from Kentucky. The sale consisted of the Sufco Mine in Sevier County, the Dugout Canyon Mine in Carbon County and the Skyline Complex on the Emery/Carbon county border.[7]
Bowie Resources is now known as Wolverine Fuels LLC [8]

Methane Plumes Detected Nearby
Global Energy Monitor researchers analyze satellite-detected methane plumes in order to determine whether they have been observed at or near the site of GEM energy assets. CarbonMapper provides satellite imagery of individual methane plumes and estimates their emission rates at the time of observation. GEM has reviewed many of these plume detections against Google Earth imagery and GEM’s own energy infrastructure tracker data. (A full description of the analysis process is available in the Global Methane Emitters Tracker methodology wiki page.) The following table lists methane plumes which were observed within the footprint of the energy asset or facility (or, in the case of oil and gas extraction areas, within 10 meters of a well).
