UPDATE: In a tense situation, EPB and Chattanooga Fire crews had the intersection of Lindsay and East 11th Streets shut down on Monday.

Initial reports say a transformer exploded, but officials are now saying a minor fault in the ground caused a small fire near a transformer, and the buildup of pressure moved manhole covers.

"It's hard to know if the weather really was a contributing factor in this case or not, so we would hate to speculate on that,” EPB spokesman J.Ed Marston said.

Last November, city workers were evacuated from city hall because of a minor explosion at the same transformer.

An electrical issue was cited as the cause of the explosion.

Fortunately, Monday’s incident was a minor situation.

"This was just more contained. It wasn't as big of an event,” Marston said.

EPB plans to inspect transformers throughout the city and replace what's necessary to make sure they don't run into this issue again.

"So, it's not like it will take a long time but unfortunately this city has been around for a while and we have other places that are like this that will have to be addressed in the future,” Marston said.

There were no reported outages from this incident.

EPB officials say they plan to have crews out first thing on Tuesday to replace the transformer.
