A fire broke out Sunday morning in the roof of a lead battery recycling facility on Yankee Doodle Road in Eagan. No one was injured.

The Eagan Fire Department responded to a call from Gopher Resource shortly before 5 a.m. and found the fire in the roof of one of the site's main buildings, according to Eagan Deputy Fire Chief Kip Springer.

About 9:30 a.m., Springer said the fire was limited to the roof, and that, to his knowledge, no products had ignited. Everyone inside the building was evacuated. He said he expected the fire to be extinguished about midday Sunday.

"I would suspect we'll be here for a few hours, but we don't have that big plume of smoke in the sky," he said.

Springer said it's not clear what caused the blaze, but because it was between layers of the roofing, the fire was difficult to reach and labor-intensive to put out.

The building has a water containment system, so water used to fight the fire will not go into storm sewers, he said.
