Ongoing Work: How is the air monitoring and air sampling data being used to protect the community and the environment?

Return to: Frequently Asked Questions

Air monitoring and sampling stations continue to run 24/7 at:

• The site perimeter
• The work areas
• In the community

We oversee results from daily air monitoring reports.

• These reports continue to show no levels of contaminants (pdf)* (particulates, mineral acid gases) above our health standards. Samples are collected at each air monitoring station. This includes at the site and in the community.
• If there were to be any elevated readings, work would stop. If changes to work processes are needed, Vistra will make the changes to fix the problem.
• For more information on these steps, see our FAQ “What will EPA and Vistra do if there are elevated readings detected by the air monitors?”

The air monitoring and air sampling data will be posted for the community to view. We are working with the county to set this up.

You can see the latest air sampling results on Monterey County’s Moss Landing Vistra Battery Fire Data Viewer.

*In the Administrative Order on Consent between EPA and Vistra, at a minimum, Vistra is required to do air monitoring for: “hydrogen fluoride, hydrogen cyanide, total volatile organic compounds, lower explosive limit, percent oxygen, particulates as a general indicator for metals, and carbon monoxide.”

In this order, Vistra is also required to do air sampling for, at a minimum: “asbestos and metals that are contaminants of concern for the site (including cobalt, manganese, nickel, aluminum, copper, lithium, and lead).”
