LCP Chemicals Inc. Site, Linden, New Jersey
Site Description
The LCP Chemicals, Inc. (LCP) site is located in an industrial area on the Tremley Point peninsula adjacent to the Arthur Kill, in
Linden, Union County, New Jersey. The site is bordered by South Branch Creek to the east, ISP Environmental Services (formerly
GAF Corporation) to the north, and Northville Industries, BP Corporation, and Mobil to the northeast, south, and west, respectively.
South Branch Creek, a tributary of the Arthur Kill, flows through a portion of the site via engineered conveyance structures on the
north side of the property. The land, originally a coastal marshland, was filled in and developed for industrial use. LCP Chemicals,
Inc., a division of the Hanlin Group, Inc., purchased the 26-acre chlorine production facility in 1972 from
GAF Corporation, who
owned and operated the facility since 1942. LCP operated the facility from 1972 through 1985, when it ceased operations.
Sludges containing mercury from the chlorine production were discharged to lagoons. In 1972, 1974, and 1979, the State of New
Jersey documented releases from the brine sludge lagoon discharging to South Branch Creek. Over the years, portions of the
site and buildings were leased to other companies, including Union Carbide, Microcell Technologies, and Kuehne Chemical
Company. In July 1991, Hanlin Group, Inc. filed for bankruptcy.

Site Responsibility
This site is being addressed through Potentially Responsible Party (PRP) actions.

Threats and Contaminants
Preliminary sampling of soil, surface water, and sediment revealed elevated levels of mercury, and other metals. Site
contaminants potentially impact the Arthur Kill, which is used for recreational boating and fishing. The peregrine falcon, northern
harrier, great blue heron, and little blue heron, all state-listed species, are reported to either breed or hunt in the salt marshes
near the Site. Prall’s Island, located approximately 1,000 feet east of the mouth of the South Branch Creek, is a breeding area and
rookery for some of these birds.

Eating contaminated fish, shellfish, crabs, and other marine organisms and accidental ingestion of site soils and sediments may
be potential health threats.

Cleanup Approach
The site is being addressed in one stage—a long-term remedial phase focusing on the cleanup of the entire site.

Response Action Status

Entire Site:
A remedial investigation and feasibility study (RI/FS), to determine the nature and extent of the contamination at and emanating
from the site and to identify and evaluate remedial alternatives, is presently underway. It is anticipated that the RI/FS will be
completed in the fall of 2004.

Site Facts:
In July 1998, the site was placed on EPA’s Superfund National Priorities List. Subsequently, EPA initiated a search for Potentially
Responsible Parties (PRPs), and issued to the PRPs that were identified notice letters and a draft Administrative Order on
Consent related to performing an RI/FS at the site. In May 1999, one PRP, ISP Environmental Services, Inc., signed an
Administrative Order on Consent for the performance of the RI/FS.

Cleanup Progress (Studies Underway)
Phase 1 of the RI/FS was conducted from October 2001 - April 2002. The results of the Phase 1 sampling effort indicated that
there were some data gaps and additional field work was necessary in order to fully characterize the nature and extent of the site
contamination. The PRP is preparing the work plan for the scope of activities to be conducted as part of the RI/FS Phase 2. EPA is
conducting a screening level ecological risk assessment for the site. It is anticipated that the RI/FS will be completed in the fall of
