The Hunters Point Power Plant closure and cleanup
Learn about the closure and cleanup process at the plant
In 1998, PG&E submitted a plan to the California Public Utilities Commission to close the plant as soon as replacement sources of electric power were brought online to ensure reliable energy for residents and businesses in San Francisco. PG&E brought nine new power transmission projects online over the next eight years. Upon completion of those projects in 2006, the CAISO (California Independent System Operator) and FERC (Federal Energy Regulatory Commission) granted approval and the plant was closed.
The cleanup process
The Department of Toxic Substances Control (DTSC) approved the Hunters Point Power Plant site cleanup plan in 2010 and the Shoreline Area cleanup plan in 2015. The plan focused on addressing impacts in soil, groundwater and Naturally Occurring Asbestos (NOA) present in the fill material generally found in the area. Work proceeded as follows:
Began soil cleanup work at the former power plant
Began groundwater cleanup work at the former power plant
Shoreline Area cleanup assessment
Completed a majority of the soil cleanup work
DTSC approved the Shoreline Area cleanup assessment
Completed a majority of the groundwater cleanup work
DTSC approved the Shoreline Area cleanup plan
Began Shoreline Area cleanup
- March 2017

A protective cover is now in place throughout the site to prevent dust and exposure to airborne, naturally occurring asbestos from serpentine rock which is native to the area. PG&E will also work with DTSC to record a deed restriction on the property that requires protective measures to be taken in relation to any redevelopment.
Now that the cleanup is finished, PG&E is working with DTSC to obtain a certificate of completion for the Power Plant and Shoreline Area work. PG&E will continue to monitor groundwater at the larger Power Plant property to confirm the treatments remain effective overtime. This work will continue under DTSC oversight.
