The AES power plant near Long Beach’s Marina area is firing up its generators, causing yellow smoke to be emitted from its smoke stacks, fire officials said.

Long Beach Fire Department spokesman Brian Fisk said the natural gas power plant, at 690 N. Studebaker Rd, received a permit from South Coast Air Quality Management District to fire up new generators and also conducted community outreach in advance, even though fire officials have continued to receive reports by locals on Sunday.

Plant officials said it is normal for yellow smoke to be emitted, it’s a regular product of combustion, when firing up generators.

The procedure began Oct. 3 and is expected to continue until Oct. 13.

Editor’s Note: A previous version of this story incorrectly identified the source of the smoke as the Haynes Generating Station operated by the Los Angeles Department of Water and Power, per fire officials.
