New Jersey Natural Gas Company Long Branch Plant
(aka Long Branch Manufactured Gas Plant)

Long Branch City, Monmouth County
PI #: 012251

As of 30 September 2016

This site is a 17-acre property located in a primarily residential area of Long Branch. Troutman's Creek, a tributary of the Shrewsbury River, flows through the site. Between 1860 and the 1950s, a series of utility companies operated a manufactured gas plant (MGP) at the property that extracted gas from coal. This process generated a viscous waste known as coal tar, some of which leaked into the ground. The primary contaminants associated with the MGP residues are polycyclic aromatic hydrocarbons (PAHs), and metals, such as arsenic and lead. Although MGP operations were phased out more than 50 years ago, contaminants from the operations remained in the soil, sediments and ground water.

New Jersey Natural Gas (NJNG) acquired the site in 1952, when it purchased the natural gas properties of Jersey Central Power & Light. Since 1991, NJNG has been addressing the soil, sediment and ground water contamination that resulted from the former MGP operations. NJNG removed contaminated soil and ground water from the former plant property and adjacent off-site properties, including Seaview Manor and the former Jerry Morgan Park. The excavated areas were backfilled with clean fill material and a soil cap was installed. The ground water pumped from the excavated areas was treated to remove contaminants prior to being discharged to the local sewage authority.

NJNG also removed contaminated sediments from the portion of Troutman's Creek that traverses the facility and installed a multi-liner system in the creek bed to prevent the underlying contaminated ground water from reaching the surface. NJNG subsequently excavated contaminated sediments from the off-site portion of the creek between the Seaview Avenue and Joline Avenue bridges and restored the wetlands areas. As part of the Troutmans Creek remediation project, NJNG dismantled the Seaview Avenue Bridge, excavated the contaminated sediments and soils near the bridge abutments, and replaced the bridge with a culvert. NJNG has delineated the contaminated soil and sediments near the Joline Avenue bridge abutments, and these contaminated materials will be removed when the bridge is replaced at the end of its normal lifespan.

NJNG is monitoring the contaminated ground water by sampling on-site and off-site monitoring wells. NJNG will use the sampling data to design a remedial action to address the contaminated ground water.

Following is a summary of the removal, restoration, and treatment activities and the amount of money spent through September 2016:

  • Total volume of soil/sediment excavated and disposed of from all on-site and off-site properties and the creek is approximately 368,500 tons.
  • Total treated water is approximately 121.5 million gallons.
  • Approximately three acres of on-site and off-site wetland areas and transitional areas were restored.

Remediation project expenditures by NJNG as of September 30, 2016 have totaled approximately $210.5 million dollars.

Monthly Updates
