Former Oroville manufactured gas plant

Overview: PG&E is working to cleanup environmental impacts related with a manufactured Gas Plant (MGP) formerly located near the corner of Huntoon and Montgomery Streets in Oroville, California. PG&E has submitted a draft cleanup plan to the California Department of Toxic Substances Control (DTSC), which oversees this work. The draft plan proposes to excavate impacted soil and dispose of it at an off-site licensed facility.


DTSC will invite the public to review and comment on the draft cleanup plan in the fall of 2017. The agency will respond to all comments received before approving or denying the plan. PG&E anticipates site remediation will begin in late 2018 and last roughly six months.

PG&E will work closely with the City of Oroville and area merchants to minimize impacts to local businesses and events. We will continue to keep the public informed with fact sheets, work notices and other outreach.


History: The former MGP operated from 1878 to 1926 providing a constant source of energy for the community’s lighting, heating and cooking needs. PG&E owned the plant from 1916 to its closure. Some byproducts of the gas making process were left buried on-site as the plant was dismantled – a common practice before environmental regulations. PG&E will clean up the property applying today’s standards.
