WASHINGTON, Oct. 31, 2013 -- Arch Coal, Inc. (NYSE: ACI) today announced that its ACI Hazard subsidiary earned the national Sentinels of Safety award for achieving the best 2012 safety record among the largest coal processing facilities in the United States.

The prestigious Sentinels of Safety awards were presented at a banquet yesterday evening in the nation's capital. This is the eighth Sentinels of Safety award earned by an Arch subsidiary operation since 2002.

"The best-in-class safety recognition was hard earned by our dedicated Hazard loading employees," said Arch President and CEO John W. Eaves. "This is true safety excellence to accomplish a perfect safety rate for more than three years while shipping millions of tons of American coal."

In 2012, employees at Hazard's Kentucky River loading facility worked 184,859 hours with an incident rate of zero, compared to the national average of 1.39 incidents per 200,000 employee-hours among U.S. coal processing facilities.

"We're honored to be recognized as the nation's safest in our class," said Greg Feltner, Hazard president and general manager. "The dedicated employees at Hazard's loading facility have operated safely for more than half a million employee-hours."

The Sentinels of Safety awards program is sponsored by the National Mining Association. Sentinels of Safety award recipients represent mining operations that have worked the most employee hours in each category without a lost-time incident. Six award winners are chosen from large and small operations in three category types, with a minimum of 4,000 hours logged without a lost-time incident.

Sentinels of Safety awards were initiated in 1925 by then-Commerce Secretary Herbert Hoover and remain the nation's most prestigious awards for recognizing safety in coal, metal and nonmetal mines. More information on the Sentinels of Safety awards is posted at www.nma.org.
