Former Watsonville - 1 manufactured gas plant

PG&E has completed the voluntary cleanup of a former manufactured gas plant (MGP) at 618 Main Street in downtown Watsonville. The six-month remediation work involved the removal of impacted shallow soil followed by full site restoration and landscaping to allow the continued operation of an on-site business. The California Department of Toxic Substances Control (DTSC) has certified that the appropriate remedial actions have been completed.

The former Watsonville-1 manufactured gas plant operated from 1871 to 1905. From 1905 to 1931, the site was used for a variety of commercial purposes including an auto dealership and repair shop. In 1931, the Coast Counties Gas and Electric Company (CCGE) opened a customer service center at the site. PG&E acquired CCGE in 1954 and continued to use the site as a customer service center until 1989 when it was leased for commercial purposes.

Site landscaping and concrete driveway post-remediation improved public right-of-ways after remediation

PG&E sold the property in 2001 and today the site contains a restaurant and a parking lot.
