Manufactured Gas Plants
Former San Rafael Manufactured Gas Plant

As part of a voluntary program under the oversight of the California Department of Toxic Substances Control (DTSC), PG&E is working to remediate a former manufactured gas plant (MGP) site at 999 3rd Street in San Rafael.
The former San Rafael manufactured gas plant operated from 1875 to 1930. The plant was shut down and put on standby status until 1960, at which time it
was dismantled.
In the 1980s, the site, as part of a larger parcel, was investigated and remediated by covering impacted soils and installing a groundwater extraction system. PG&E sold much of the site in 1998 and it has been redeveloped as a business park. Ongoing monitoring confirms that the remedy continues to be effective for treating affected groundwater and protecting humanhealth and the environment.
A former PG&E service center and parking lot occupy the portion of the site still owned by PG&E. In July 2010, DTSC approved an investigation report prepared by PG&E for this portion of the property. The report defines the extent of impacts to soil and groundwater from historical gas plant operations.
A cleanup plan, known as a Remedial Action Plan (RAP), has been prepared for this site and was available for public review through November 8, 2012. A public meeting on the RAP was held on October 25, 2012 at the San Rafael Community Center. DTSC considered and responded to all public comments received prior to approving the RAP. Cleanup work is expected to begin in spring 2014.
