Air Monitoring and Controls

Air monitoring station locations

In an effort to protect the community and site workers, PG&E has established a comprehensive dust control and air monitoring program. The program has been in place since dismantlement work began in 2007.

Under this program, any time our air monitoring results record naturally occurring asbestos (NOA) or dust levels that are greater than or equal to "trigger"” levels (protective levels set by the Bay Area Air Quality Management District [BAAQMD]), we take precautionary measures. We stop work and evaluate on-site and off-site activities and weather and wind patterns to determine whether our NOA and dust control measures are effective or need to be adapted to current conditions. If changes to our dust control measures are needed, we do not resume work in the area until the new measures are in place and the air monitoring results are back below the trigger level.

The program meets or exceeds all federal, state and local regulatory requirements for monitoring and mitigating airborne dust. All air monitoring results are reported to the California Department of Toxic Substances Control (DTSC), the lead agency overseeing the cleanup, and BAAQMD.

Important Resources

Air monitoring results submitted to the agencies are available in the document archive.

In addition, a summary of air monitoring results is sent to the Project Advisory Committee and interested parties on a weekly basis. These weekly updates are also available in the archive. If you would like to receive the weekly project update contact us at communityfirst@pge.com or call 415-626-3055 to be added to the email distribution.

You can also access air monitoring reports on the DTSC online repository of information related to the cleanup called Envirostor. Clicking on the “Activities” tab will take you to a collection of technical documents, including air monitoring reports.
