Former Merced manufactured gas plant

Project overview: In 2017, PG&E will begin cleanup of soil impacts from a former manufactured gas plant (MGP) that operated at 560 West 15th Street in Merced, CA (site). PG&E conducts all project work voluntarily with oversight provided by the California Department of Toxic Substances Control (DTSC), City of Merced and San Joaquin Valley Air Pollution Control District.

 

Work will last roughly seven months and includes a combination of excavation and off-site disposal of shallow soil and adding a cement mixture to solidify impacts to deeper soil in place. This green approach will protect long-term public health and the environment while minimizing impacts to the local community and the amount of soil being placed in landfills.

Project controls: Safety is of utmost importance to PG&E. Work will be conducted in accordance with a DTSC-approved health and safety plan that includes proven best practices for air and vibration monitoring, dust management and truck traffic control. PG&E will continue to keep the community informed about the project through fact sheets, work notices and other outreach, as appropriate.

 

Site history: The former MGP operated from 1883 to 1930 and provided a constant source of energy for the community's lighting, heating and cooking needs prior to the arrival of natural gas. Some byproducts of the gas making process were left buried on-site as the plant was dismantled – a common practice before environmental regulations – and PG&E will be cleaning up the property in accordance with today's standards.
