SAN ANTONIO -

Fire crews battled a massive fire that broke out late Monday night at a compost company on the far East Side.

The fire was reported around 9 p.m. at New Earth Soils and Compost off Interstate 10 near Foster Road.

San Antonio fire fighters believe it was initially an electrical fire that spread to pallets sitting on a conveyor belt.

The fire then spread to a large pile of mulch and caused massive flames to shoot into the sky.

A least a dozen SAFD units responded to the fire along with three Bexar County fire departments.

"We were watching TV and all of a sudden we saw the glare on our door, and we looked outside and the flames were like real high," Salvador Bazaldua,. who lives near New Earth Soils and Compost said.

The smoke is still visible from his front yard.

"You're kind of concerned, because you know it's kind of dry out here and you're always concerned that it could spread a little," Salvador Bazaldua Jr. said.

Fire officials said the fire is under control, and they are working on it in layers.

Fire fighters are putting water on the top of the pile, then as that cools down, they are pulling it back and working on what's underneath it.

No structures or homes have been threatened by the fire.

No injuries have been reported. Crews will be on scene until the fire is put out, but fire officials said the blaze is likely to continue for a few days.

They also expect the smoke in the area to last for days.
