Thank you for visiting the website for the PSE&G Plainfield former Gas Works Site Remediation and Restoration Project, located in Plainfield, NJ. We are committed to providing the community with timely information throughout the duration of our activities. We will issue and post weekly updates on our progress. 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.

Temporary Closure of the East Fourth Street Extension

The East Fourth Street Extension is closed to traffic between Roosevelt and Watchung avenues. The road will be closed for the duration of a PSE&G remediation project that also includes the parking area behind the City of Plainfield Police Department building. Work began in January 2019 and is expected to be substantially completed by the end of the year.

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.
