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 expected to take place in the spring 2020 to complete any remaining site restoration and landscaping. Your questions and comments are welcome.

The project will be separated into four phases. Restoration of each phase will begin immediately following its completion.

Work has been performed to minimize impacts to parking and adjacent roadways as much as possible.


Background

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.

The East Fourth Street Extension Has Re-Opened

The East Fourth Street Extension between Roosevelt and Watchung avenues re-opened to traffic on December 19, 2019. The road was closed as part of a PSE&G remediation project that began in January 2019. The project, which has paused for the winter, will remobilize in spring 2020 to complete the remaining restoration work.

The work is being performed in cooperation with the New Jersey Department of Environmental Protection and the City of Plainfield. For more information visit www.plainfieldmgp.com, call the PSE&G Project Information Line at (888) 970-1006, or email questions to comments@PlainfieldMGP.com.
