Mining

Coal is a valuable resource and is used as the fuel for most of PacifiCorp's generating plants. Approximately 40 percent of the coal used in the PacifiCorp system is produced from captive mines. PacifiCorp's mines produce approximately 9.6 million tons of coal annually from both surface and underground mines. Surface operations produce approximately 2.7 million tons per year and underground operations produce approximately 6.9 million tons per year.

In Wyoming, PacifiCorp operates and has partial interest in Jim Bridger Mine and owns the Dave Johnston Mine, which is in final reclamation. The company also owns and operates the Deer Creek Mine in Utah, and has a partial interest in the Trapper Mine in Colorado.

These mining operations produce low-cost, quality fuel for PacifiCorp's power plants and are nationally recognized in productivity, safety and the environment.

As part of the company's commitment to the environment, it has introduced new clean technologies to reduce the impact of its mining operations on the environment.
