Canton Marathon Oil refinery conducts controlled burn

CANTON, Ohio - Drivers and local residents saw a huge fire at the Marathon Oil refinery in Canton Tuesday evening.

But it was all planned, according to the company.

A Marathon representative told Fox 8 that the fire is called a "controlled flaring" and is used as a "safety valve."  He adds that "operational circumstances often require it."

The burn still made for quite a blaze that could be seen for miles and miles.
