PG&E Shell Pond

PG&E Shell Pond is a 73-acre former wastewater pond (site) located at the foot of McAvoy Road in Bay Point, California. The pond is located within a larger 292-acre parcel owned by PG&E. Under a plan approved by the California Department of Toxic Substances Control (DTSC), PG&E proposed to clean up the pond and restore the area to its natural tidal wetland habitat and open space. The work to implement this plan began in 2011 and was stopped in January 2012 due to odors caused by the construction activity which could not be contained on-site.

PG&E is studying alternative approaches to the pond cleanup that limit off-site construction impacts. This redesign process will continue through 2013 and will include some small scale testing of additional cleanup and site management methods at the site during the year.

DTSC will continue to oversee and approve all work at the pond and we will continue to keep the community informed as the project progresses.
