Wyoming: 60,000 pounds of an explosive chemical lost during rail shipment

About 60,000 pounds of a chemical used as both a fertilizer and an explosive is missing after likely disappearing during a rail trip from Wyoming to California last month, according to federal records.

A rail car carrying ammonium nitrate left a plant operated by explosives manufacturer Dyno Nobel in Cheyenne, Wyoming, on April 12, according to an incident report filed May 10 by a representative of the company with the National Response Center.
