The Chevron refinery in Richmond, CA, is under watch after recent flaring episodes, the most recent of which occurred last Wednesday.
The March 6 episode, as well as flaring events that took place in January and February, were the result of electrical power outages during heavy rain storms, according to the Bay Area Air Quality Management.
The regional agency is investigating each episode “to ensure public health is protected,” Bay Area Air Quality Management officials said.
Flaring also occurred because of a new hydrogen plan, according to the agency.
Flares are “important safety devices” that burn refinery process gasses that would otherwise be directly released to the atmosphere, according to the news release.
Chevron is required to submit a “Flare Causal Report” detailing the cause of each incident and plans to prevent recurrent flaring.
