Cleanup Plan announced for Welsbach & General Gas Mantle Superfund Site (Camden Radiation) at Gloucester Marine Terminal
The U.S. Environmental Protection Agency has finalized changes that add measures to its cleanup plan to address radiological contamination at the former Welsbach Facility at the Welsbach & General Gas Mantle (Camden Radiation) Superfund Site. The former Welsbach Facility is located within the footprint of the Gloucester Marine Terminal in Gloucester City and Camden, New Jersey. These changes adapt the original plan to address some additional radioactive material that was found at the site, while minimizing disruptions to the port facility’s operations.
“This updated cleanup plan highlights EPA’s ongoing commitment to protecting public health and ensuring a safe environment for the port communities,” said EPA Regional Administrator Lisa F. Garcia. “We continuously assess conditions and adapt our strategies to ensure the cleanup remains scientifically sound while accommodating the ongoing operations at the Gloucester Marine Terminal.”
The amended cleanup plan focuses on addressing radiological contamination at the former Welsbach Facility. The plan adds key actions that include:
- Removal of radiologically contaminated soil and waste material from selected areas at the Gloucester Marine Terminal, including under buildings, to a depth of approximately 10 feet.
- Disposal of excavated material at an off-site, licensed, and EPA-approved facility.
- Backfilling of excavated areas with clean soil to restore the site.
- Restoring paved areas to their previous condition.
- Implementing institutional controls, such as deed restrictions, to limit access to remaining contaminated areas.
EPA’s changes to the original cleanup plan are necessary after EPA found a greater volume and depth of soil contamination than initially assessed, including radiologically contaminated materials beneath structures at the port facility. Removing these materials would significantly increase the original cleanup costs, delay the project, and cause major disruptions to port operations. EPA’s study on current site conditions confirms that the amended cleanup plan will protect public health and the safety of port workers, even with some contamination remaining at depth and under certain structures after the cleanup is completed. Removal of contaminated material under structures would only be completed if and when the property owner demolishes those structures.
EPA added the Welsbach & General Gas Mantle (Camden Radiation) site to the federal Superfund list in 1996. Because of the nature, size and complexity of the site, EPA divided the investigation and cleanup into multiple phases. In 1999, EPA selected a plan for the first phase of the cleanup, which included the excavation and off-site disposal of radiologically contaminated soil and building materials, and backfilling of the areas with clean soil. To date, EPA has removed more than 200,000 cubic yards of radiologically contaminated soil and building materials from more than 90 properties in the Gloucester City and Camden areas and has investigated more than 900 properties.
