Moss Landing Air: What air monitoring activities did you do during the January fire response?

Return to: Frequently Asked Questions

During the Fire

At the request of local agencies, EPA conducted perimeter and community air monitoring beginning the morning January 17.

• We had nine air monitors set up at and around the property.
• The monitors looked for mineral acid gases like hydrogen fluoride and particulates.
• After smoke subsided, EPA consulted with Monterey County and transferred air monitoring stations to Vistra to continue monitoring.
• We shared our air monitoring data with state and local officials.
• Please visit Monterey County’s “Moss Landing Vistra Battery Fire” dashboard for more information about their response to the fire.

EPA's air monitoring data was provided to local agencies for analysis to inform public health decisions.
