Sufco’s employees completed 797,517 hours incident-free in 2010. Large coal operators in the states of Utah, Wyoming, Colorado, New Mexico, North Dakota, Montana, Arizona and Texas competed for the top award.

“The employees of Sufco are very deserving of this recognition for their hard work and dedication to workplace safety,” said John W. Eaves, president and COO, Arch Coal. “In addition to a perfect safety record, Sufco also achieved a perfect environmental record during 2010. Sufco achieved Arch Coal’s Perfect Zero and received the Arch Coal President’s Award for such high performance levels last year.” Sufco sold more than 6 million tons of low-sulfur coal in 2010.
