Former Fresno - 1 Manufactured Gas Plant


PG&E has completed soil remediation activities at the site of a former manufactured gas plant (MGP) that operated at 211 North Thorne Avenue in Fresno (site) from 1918 to 1929. All work was performed voluntarily under the oversight of the California Department of Toxic Substances Control (DTSC).

Cleanup activities included the removal and off-site disposal of roughly 20,370 tons of impacted soil from the site, and in the adjacent railroad right-of-way and public right-of-way (ROW) along North Thorne Avenue and West Voorman Avenue.

After remediation work was complete, PG&E constructed two new buildings and parking at this property to support its continued use as a service yard and gas load center. This work was completed in November 2018. PG&E will continue to keep the community informed about the project as needed.


The former MGP operated from 1918 to 1929 providing a constant source of energy for the community’s lighting, heating and cooking needs. Some byproducts of the gas making process were left buried on-site as the plant was dismantled – a common practice before environmental regulations.
