Background: The project will remediate impacts to soil from the operations of a former manufactured gas plant (MGP) operated by a predecessor company of PSE&G in Trenton from the late 1840s to late 1890s. Approximately 100,000 tons of MGP-impacted soil will be excavated. Any infrastructure related to the former MGP operations that remain underground also will be removed. Most of the work will be performed within a temporary sprung structure (i.e., tented enclosure). Excavated soil will be transported to a permitted off-site soil treatment and disposal facility. The excavated areas will be backfilled with certified clean fill and restored to the pre-existing conditions. Groundwater encountered during soil remediation activities will be treated and conveyed off site in accordance with permitting.

The project is anticipated to take approximately 18 months to complete. All work is being performed in cooperation with and under the oversight of the Licensed Site Remediation Professional (LSRP), and in accordance with the requirements and guidance of the New Jersey Department of Environmental Protection (NJDEP).
