Thank you for visiting the website for the PSE&G Plainfield former Gas Works Site Remediation and Restoration Project, located in Plainfield, NJ. The remediation work was completed between January 2019 and October 2019. Restoration of roads, parking areas and sidewalks has been completed. A limited remobilization is anticipated to begin the week of April 6, 2020. The work will complete the remaining site restoration and landscaping, and is expected to be completed this spring. Your questions and comments are welcome.
Prior to the widespread availability of natural gas, gas was “manufactured” through a process of heating coal in specialized ovens. These facilities, called Manufactured Gas Plants (MGP), were common in many urban areas of the United States during the late nineteenth and early twentieth centuries.
Predecessor companies of Public Service Electric and Gas Company (PSE&G) operated an MGP in the City of Plainfield in Union County from about the late 1860s or early 1870s until 1926, when gas production facilities were decommissioned. The site was used as a gas holder facility and then for PSE&G’s district operations headquarters until 1953.
The City of Plainfield purchased part of the property for a road expansion in 1953 and the remainder of the property in 1957. The site is currently the location of the parking lot for the Plainfield Police Department, a municipal parking lot and a part of East Fourth Street. Foundations, pipes and other remnants of the MGP operations remain in place below ground. The Police Department building is not located on the footprint of the former MGP site.
An unintended consequence of the MGP industry was adverse effects on the environment from coal tar and various by-products.
