Site Background:
The facility has produced chemical dyes since 1936 on the 1,300-acre
site. Opened by Sodyeco, the plant was taken over by American
Martin-Marietta in 1958 and sold to Sandoz Chemicals Company in
1983. Sandoz Chemical Corporation changed its name to Clariant
Corporation in July of 1995. The plant manufactured liquid sulfur
dyes and later in the early 60's expanded its product line to
vat and disperse dyes. Since that time the company has produced
specialty chemical products for the agrochemical, electronic,
explosive, lithographic, pigment, plastic, rubber and general
chemical industries. The facility is currently active and is a
Resource Conservation and Recovery Act (RCRA) regulated facility.
In June 1982 a hazardous waste site investigation of the Sodyeco
Site was conducted by EPA. Results of surface water, groundwater
and sediment samples revealed the presence of organic contaminants
in the groundwater and small amounts in the surface water. The
Sodyeco site was placed on the National Priorities List in December
1982. EPA and Sandoz signed a remedial investigation and feasibility
study Consent Agreement on February 10, 1986. The Record of decision
selecting the remedy for groundwater and soil contamination was
issued in September 1987.
Cleanup Progress: Actual Construction Underway
The groundwater pump and treat system construction was completed in March of 1990. The extraction systems for CERCLA areas A-C were started April 23, 1990, Area D was started the following day. Area E was started in June of 1990. The installation of the asphalt cap proposed for CERCLA Area B was completed October 25, 1989.
During the installation of the in-situ vacuum extraction system in September 1990 at Area C, unknown waste materials were encountered. Exploratory trenching revealed the presence of buried drums, glass jars containing "chemical crystals" and a tar-like substance in one central location. Sandoz contracted GSX Services, Inc. of Pinewood, South Carolina to remove the buried drums and contaminated soil. The excavated drums were emptied and disposed of as non-hazardous waste at the GSX Pinewood secure landfill. The contents of the drums were combined and disposed of by SE Chemicals/Giant Cement using a fuel blending process. Area D, the last area to be treated, was treated via excavation and off-site treatment. Physical construction at all CERCLA areas was complete as of September 1999. The remedial design and remedial action were conducted under an amendment to the Resource Conservation and Recovery Act (RCRA) Part B Permit, and is being overseen by EPA's Superfund program. The first Five Year Review was conducted in September of 2002. It was concluded in that Five Year Review that the remedy had addressed all immediate threats and though there was a need for additional analysis of the containment of the groundwater plume, none of the nearby surface water bodies had be impacted by Site contamination. The Second Five Year Review was completed September of 2007. Although the containment studies that were recommended in the previous five year review have been conducted, information obtain during the process reveal additional work is needed to make the final determination as to the status of the long term protectiveness of the Site. As in the first five year review, the second five year review found the Site to be protective in the short term and further confirmed that all immediate threats have been addressed. |
