EPA proposes $11 million clean up for New Jersey's standard chlorine chemical suite.
The U.S. Environmental Protection Agency (EPA) has proposed a plan to clean up contamination at the Standard Chlorine Chemical Co. Inc. Superfund site in Kearny, New Jersey. The site is part of the New Jersey Meadowlands and on the banks of the Hackensack River.
Past manufacturing operations by various companies led to extensive contamination of the site with a number of hazardous chemicals including polychlorinated biphenyls (PCBs) and dioxin. This segment of the cleanup is estimated to cost $11 million.
Previous actions have been taken by parties responsible for the pollution with oversight by the New Jersey Department of Environmental Protection (NJDEP) and the EPA to address the immediate risks to the public. Dioxin and asbestos have been collected and disposed of at facilities licensed to receive the waste. Many of the contaminated buildings on the site were demolished and removed. Two contaminated lagoons were emptied of water, filled with clean material and covered.
A slurry wall was installed between the site and the Hackensack River to keep contamination from moving into the river. A system of pumps is being used to bring the polluted groundwater to the surface where it can be cleaned. Fish consumption warnings have been issued for the Hackensack River.
The EPA's plan proposes a targeted cap that would extend over the remaining uncovered areas, as well as upgrades to existing covers, to prevent soil disturbance. Some areas of the site where soil is heavily contaminated have already been covered by a cap to prevent contaminants from spreading.
The proposed plan calls for a cap that would extend over all areas not yet covered, as well as upgrades to existing caps. The plan proposes the demolition of five dilapidated buildings remaining on the site and the continuation, maintenance and operation of all the previous cleanup remedies.
The plan proposes land use controls such as a deed notice and other controls that would prohibit the use of the groundwater and prohibit using the site for any residential purposes.
The 25-acre site was used for chemical manufacturing by various companies from the early 1900s to the 1990s. Operations at the site included the refinement of naphthalene for use in the production of certain industrial products, the processing of liquid petroleum naphthalene, the manufacturing of lead-acid batteries and drain-cleaner products and the packing of dichlorobenzene products.
The soil, groundwater and two lagoons were contaminated with dioxin, benzene, naphthalene, PCBs and volatile organic compounds. The site was littered with tanks and drums containing hazardous substances including dioxin and asbestos. After sampling the site and requiring short-term pollution control measures, NJDEP requested that the EPA add the site to the Superfund list. The site was added to the federal Superfund list in September 2007.
