Southern Utah Fuel Company, Sufco, has never been a railroad mine. Its coal is trucked to the railroad loadout at Sharp, 78 miles north and west, near Levan, Utah. A railroad has been proposed from Salina to Sharp, but economic conditions continue to delay its construction.

In September 2013, a 8.3 mile paved road was completed in Quitchupah Creek Canyon, allowing Sufco coal to be trucked eastward to customers in Castle Valley, including Rocky Mountain Power's power plants at Hunter, 37 miles, and Huntington, 56 miles.

The following history of Sufco comes from the Garfield County News, November 26, 1981:

The company was born in 1941 when Vernal J. Mortensen, a partner in Western Creamery in Monroe, Sevier County, found himself with a small amount of cash on hand when the Creamery was sold to Pet Milk Co. He met an old friend, a miner and prospector, who talked about some coal property in Convulsion Canyon located northeast of Salina.

Two Salt Lakers, named Thomas and Lund, already had begun development of the coal seam, with the anticipation of shipping the coal on the railroad. The plan was that the Denver and Rio Grande would build a main line from Denver to Los Angeles across the Sevier-Emery summit and through Salina. However, the railroad changed its mind and instead built the main line through Carbon County, to take advantage of the coal mining and shipping there, and on into Provo and Los Angeles. At that point the two Salt Lake developers abandoned the project. Mr. Mortensen recalls that previous work revealed a 13-foot coal seam, free from bone streaks and of a good marketable quality. Mr. Mortensen and three partners incorporated in 1941 and took on, what was then, a formidable task. His partners were Ren Hansen, Gus Hansen and Jack Robinson. Their first purchase was a used Caterpillar tractor and they started to build a road. That road had to be an 11-mile stretch over very rough terrain, requiring several month's of work. The task was finally complete and the road was made passable for small bob-tailed trucks.

The first coal was mined with a used Goodman short-wall cutting machine. The crews hand-loaded the coal for the first six years. By 1948, they had increased production to almost 30,000 tons a year and were selling coal from the Salina tipple instead of at the mine.

By 1973, the SUFCo Mine was producing about 340,000 tons of coal a year. In 1973 the Mortensen family and partners sold the mine to Coastal States Gas Corporation, a Houston energy firm. With growth and expansion continuing, the SUFCo Mine now produces 2.3 million tons a year.

To handle the volume, Coastal last year [1980] built a stockpiling and coal loading facility at Levan to handle 100-car unit trains.

The following comes from United States Department Of Labor, Mine Safety And Health Administration, 2004:

The SUFCO Mine is an underground bituminous coal mine located approximately 30 miles northeast of Salina, Sevier County, Utah. The mine was originally opened in 1941 and was known as the Convulsion Canyon Mine. In 1974, the mine was purchased by Coastal States Energy Company, and a subsidiary, Southern Utah Fuel Company, was created to operate the mine. In 1997, ARCO Uinta Coal Company (ARCO) purchased 65 percent ownership of the property, and Itochu Coal International, Inc. (Itochu) of Japan purchased the remaining 35 percent. At that time, Canyon Fuel Company, LLC (Canyon Fuel) was formed to operate the mine. In 1998, ownership again changed as Arch Western Resources, LLC purchased the 65 percent ownership from ARCO, while Itochu continued its 35 percent ownership.

The mine produced 7.13 million tons of coal in 2003 with 281 employees. Daily production was approximately 28,500 tons. The mine worked two 10-hour production shifts and one overlapping 10-hour maintenance shift per day, five days per week. The mine has one retreating longwall section and two continuous mining machine development sections. The average seam height in the Upper Hiawatha Seam, in which the mine is located, ranges from 8.5 to 13 feet.

The current longwall section is located in the 3 Left Pines East panel, approximately 12 miles from the main portals. The face is 930 feet wide. A Joy 7LS3 shearing machine is used to cut the coal and a DBT PF5/2000/1342 armored face conveyor and stageloader convey the coal to the 60-inch panel belt conveyor. Two-legged Joy 2 x 970 UST shields provide roof support for the face.

February 1976
Construction of the coal loadout at Sharp was started in February 1976, and was completed at a reported cost of $5 million. The initial loading process used just a front-end loader, which was housed in a small building on-site. (Provo Daily Herald, February 29, 1976; The Daily Spectrum, St. George, May 3, 1981)

P&M was presently furnishing 1 million tons per year, half of the generating station's requirements. (Coal Age magazine, August 1983, page 35)
