Former Eureka manufactured gas plant

Project update: PG&E has begun an eight-month cleanup project to address contaminated soil at the site of a former manufactured gas plant (MGP) near West 14th and Railroad Streets in Eureka, California (site). The North Coast Regional Water Quality Control Board (Water Board) oversees this voluntary project and work is coordinated with the City of Eureka and the North Coast Unified Air Quality Management District.


Work will include a combination of on-site treatment and off-site disposal of soil containing chemical residues from historical gas-making operations. This plan allows for site remediation while minimizing impacts to the community.


Community Protection Measures: Safety is of the utmost importance to PG&E and work will be conducted in a way that protects workers and the community. This includes conducting most of the work in a large negative-pressure tent to minimize odor and dust impacts; using dust control measures such as water and foam; completing air and vibration monitoring during work activities; working during City-approved hours; using appropriately sized equipment; and using flaggers to safely manage truck, car and pedestrian traffic as trucks enter and exit the site.


PG&E will continue to keep the community informed about this project through fact sheets, work notices and other outreach, as appropriate.

Site history: The MGP and a steam electric power plant began operating at the site in 1902. PG&E acquired the site in 1927, shut down the MGP operations in the early 1940s and removed the operating structures before selling the site in the 1960s.


The former MGP site now consists of a privately-owned parcel operating as a lumber yard on the west side of Railroad Avenue, and a PG&E-owned parcel on the east side of Railroad Avenue used for general construction and substation operations. In 2001, PG&E completed cleanup of the company-owned parcel, and in 1997 and 2012, cleaned and closed in-place former underground fuel oil pipelines beneath Railroad Avenue and Waterfront Drive. In fall 2016, PG&E safely relocated a section of natural gas pipeline that passed beneath the site to enhance long-term operational safety once the property is remediated.
