The U.S. Attorney's Office says Jamie Billy of Tuba City is charged with one count of willfully and maliciously setting fire to the Navajo Nation Fire Department station.
The Department of Alcohol, Tobacco, Firearms and Explosives says a passer-by noticed the station on fire in the early morning hours of Aug. 5.
The crew was not in the station because of a call.
The fire started in the station truck bay and caused damage to a fire truck and to the station.
Billy is scheduled to appear in U.S. Magistrate Court Thursday to determine whether he should be released from custody until his trial.
