Manufactured Gas Plants

Former Watsonville-2 Manufactured Gas Plant

History: The former Watsonville-2 manufactured gas plant (MGP) operated from 1905 to 1931. All buildings and plant structures were later torn down. PG&E built an underground gas regulating station on-site in the late 1950s and currently uses the site for storage of construction materials. Investigations were performed at the site to determine the extent of cleanup necessary for soil and groundwater.

Overview: In July 2010, environmental remediation work at the site was completed. This work was part of a voluntary program under the oversight of the California Department of Toxic Substances Control (DTSC). The seven-month-long project involved the removal of impacted soil beneath the footprint of the former MGP. To maintain an open dialogue with the community, PG&E representatives worked with State officials to hold public meetings and conducted door-to-door outreach before, during and after construction activities.

Improved public right-of-ways after remediation

Community Benefits: During the work, PG&E minimized impacts to the community by rerouting trucks to avoid the residential neighborhood, varied work hours to meet the needs of nearby residents and businesses, and performed daily street sweeping. Some benefits of the project included planting of trees, repaving of an alley and installation of sidewalks, fences, curbs and gutters along the public right-of-way.

Sustainability: Sustainable practices are important to PG&E. We try to reduce our carbon footprint on environmental remediation projects to the greatest extent possible. On this project, we were able to recycle 714 tons of material, reduce greenhouse gas emissions by about 132 tons and contribute $1,228,000 to the local economy to date.
