LCP Bridge Street Fact Sheet

LCP Sub-Site Under Review

Description

The LCP Bridge Street plant is located in the Town of Geddes, immediately south of the New York State Fairgrounds. Land uses to the east and west are industrial. The Village of Solvay lies to the south.

Allied Chemical (now a part of Honeywell, Inc.) began operating a “chlor-alkali” chemical plant at this location in 1953. Caustic soda (NaOH) and liquid chlorine (Cl2) were manufactured here using the “diaphragm cell” and “mercury cell” electrolytic processes. Bleach, and hydrochloric acid were also produced here. Allied sold the plant to Linden Chemicals and Plastics (LCP) in 1979. LCP continued to operate this plant until 1988, when it was it was shut down after a series of accidental chlorine releases to the air. The plant owner (Hanlin Group) was also fined by OSHA for numerous safety violations, and in 1992 filed for bankruptcy.

A small portion of the site was used by Allied Chemical from 1956 to 1969 for manufacturing hydrogen peroxide. These operations contaminated local groundwater with xylene.

An aerial photo of the LCP site when surface soils were being processed to remove mercury. The Grandstand at the NYS Fairgrounds can be seen in the background. The turquoise line shows the approximate placement of the slurry wall which is designed to prevent contaminants from leaking off-site. The wall consists of a trench dug 30-70 ft into the earth, filled with bentonite clay.

The wall consists of a trench dug 30-70 ft into the earth, filled with bentonite clay.

In October 2004, a $14 million cleanup effort of the main plant site (Operable Unit-1) began, including these major components:

  • removal of contaminated sediments from the West Flume (these were moved to the LCP site)
  • treatment of mercury-contamination in the top six feet of soils excavated from certain areas of the LCP site. Over seven tons of elemental mercury was recovered using a soil-washing process. All contamination in deeper soils, including many tons of elemental mercury, was left in place.
  • installation of a slurry wall around the perimeter of the site (see Fig. 2)
  • installation of a temporary cap and a groundwater collection system.These activities were completed in 2008. A final cap has yet to be installed. The site is fenced and security is maintained to minimize public exposure to on-site contamination.
Future actions

A final cap over the 20-acre site has yet to be installed. Current plans call for the addition of >100,000 cu. yards of contaminated sediments from Geddes Brook and Ninemile Creek at the site. Groundwater from the site is being pumped and treated continuously. This will need to be continued into the future indefinitely.
The former hydrogen peroxide plant is being treated as a separate cleanup operation (Operable Unit 2, or OU-2). The remedial investigation (RI) for OU-2 has been completed and approved. A Feasibility Study (FS) which examines different cleanup options is currently under review.

Summary of Project Completion Dates

Projects associated with this site are listed in the Project Completion Dates table and are grouped by Operable Unit (OU). A site can be divided into a number of operable units depending on the complexity of the site and the number of issues associated with a site. Sites are often divided into operable units based on the media to be addressed (such as groundwater or contaminated soil), geographic area, or other factors.
