Former Oakdale manufactured gas plant

As part of our commitment to environmental responsibility, PG&E successfully completed the remediation of a former manufactured gas plant (MGP) in early September 2015 that operated in Oakdale, California from 1913 to 1930. Located at 811 West J Street, PG&E will continue operating a service center, which has been located at the site since 1933. All work was performed voluntarily with oversight provided by the California Department of Toxic Substances Control (DTSC) to bring the property up to today's environmental standards that are protective of human health and the environment.

Remediation work included the excavation and off-site disposal of soil contaminated with historic gas plant residues, backfill of excavated areas with clean fill, and site restoration. In addition, PG&E completed earlier remediation work in summer 2009, 2010 and 2012 to remove residues on neighboring properties.

The new site of PG&E service centre

PG&E conducted extensive community outreach prior to the start of remediation and throughout the remediation process. We will continue to keep the community well informed about this project through fact sheets, work notices and other outreach as appropriate.
