Moss Landing 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 run during hours of work 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 elevated levels of contaminants are detected,, 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 happens if data shows increased levels of contaminants in the air and how does EPA respond?”
The air monitoring and air sampling data is posted on Monterey County’s Moss Landing Vistra Battery Fire Data Viewer.
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 (pdf) between EPA and Vistra, at a minimum, Vistra is required to do air monitoring for: hydrogen fluoride and particulates. In the case another fire occurs, they much increase their monitoring to include hydrogen cyanide, total volatile organic compounds, lower explosive limit, percent oxygen, 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).”
