Trail Mountain #9 Mine
TRAIL MOUNTAIN #9 MINE - Active Operation, Permit ACT/015/009
The Trail Mountain Mine is located on the eastern edge of the Wasatch Plateau Coal Field, approximately 12 miles west of Orangeville, Utah. Mining at or near the Trail Mountain Mine began in 1898 and a large scale operation started in 1909. Mining continued until 1967 when the mine was shut down for ten years. The mine was re-opened in 1977 and has had several owners since then. The Trail Mountain Mine was purchased from Arco Coal in 1992 by PacifiCorp and is operated by Energy West Mining Company, a wholly owned subsidiary of PacifiCorp.
The Trail Mountain Mine encompasses about 3,500 acres, a combination of fee lands and federal ownership. Mining is by the longwall method in the Hiawatha seam with an annual production of about 4 million tons of coal. Coal produced from the Trail Mountain Mine is transferred via beltline through the Cottonwood/Wilberg Mine to the surface loading facilities located in Grimes Wash. The coal is loaded onto trucks and hauled to the Hunter Power Plant where it is used to produce electricity.
