No Injuries in Cheyenne Refinery Fire

by Taylor Viydo, 
A Holly Frontier spokesman says a leak in a refining unit caused a fire at the company's Cheyenne refinery on Wednesday afternoon. 
Don Finley of Holly Frontier says the blaze started just after noon when leaking petroleum from a coker unit caught fire. A coker unit breaks down carbon chains in sour-crude oil. 
Finley says on-site first responders acted quickly and extinguished the fire at 1:45 p.m. The Cheyenne Fire Department was not called and did not respond to the fire. 
No evacuation orders were issued and the fire was contained to the refinery. Finley says the fire had no off-site impacts.
No one was injured during the incident.
