Monterey County supervisors on Tuesday declared a state of emergency in response to last week's major fire at the Vistra lithium battery plant in Moss Landing.

A fire at the world’s largest battery storage plant in Northern California is smoldering after sending plumes of toxic smoke into the atmosphere.

A plume of material released from the plant contained hydroflouride, a toxic gas, that is now being monitored by Monterey County.

As the fire lithium battery storage facility that led to evacuations in Moss Landing last week continues to smolder days later, concerns are being raised about the impacts to the surrounding environment.
