Former Monterey manufactured gas plant

Current work: PG&E is in the process of upgrading electrical equipment at the Monterey substation to increase the safety and reliability of our distribution system. This work allows us access to access and remove soil contaminated from historic gas making activities. From late February to October 2022, PG&E will excavate contaminated soil, dispose of it off-site and backfill excavations with clean fill. This work is overseen and approved by the California EPA, Department of Toxic Substances Control, referred to as DTSC. Once contaminated soil is removed, state-of-the-art electrical equipment will then be installed from November 2022 to May 2023.

Former Monterey Manufactured Gas Plant: The former Monterey manufactured gas plant (MGP) operated from 1902 until 1929 at what is now the PG&E Monterey substation at the corner of Figueroa Street and Del Monte Avenue. Historic gas making left gas plant residues in soil and groundwater and PG&E is working with DTSC to remediate the site.

Public Safety and Outreach: Safety is of utmost importance to PG&E. Environmental cleanup work is conducted in accordance with a DTSC-approved health and safety plan that includes proven best practices for air and vibration monitoring, dust management and truck traffic control, as well as safety measures to reduce the risks of COVID-19. PG&E will continue to keep the community informed about the project through fact sheets, work notices and other outreach, as appropriate.
