Current Site Status
The LCP Chemicals Georgia site includes an area where various industrial facilities operated from the early 1920s until 1994. EPA placed the site on the National Priorities List (NPL) in 1996 because of contaminated ground water, soil and sediment resulting from facility operations. EPA, the Georgia Environmental Protection Division (Georgia EPD) and the site’s potentially responsible parties (PRPs) are investigating site conditions and are taking steps to clean up the site in order to protect people and the environment from contamination. Site contamination does not currently threaten people living and working near the site. By investigating site conditions, undertaking removal actions and limiting access to contaminated areas, EPA, Georgia EPD and the site’s PRPs continue to protect people and the environment from site contamination.
The 550-acre site is located north of Brunswick, Georgia, and consists primarily of tidal marsh. The remaining portion of the site includes former petroleum process buildings, former mercury cell buildings and an administration office. The site is located near a paper company, a county facility and an estuary. The site is bordered by the Turtle River marshes to the west and south, and urban populations of Brunswick to the north and east. Several residences are located south of the site. The site also includes a 10.5-acre highly alkaline caustic brine pool. Caustic brine is a salty solution that can cause burning or corrosion.

From the 1920s to 1994, facilities at the site included an oil refinery, a paint manufacturing company, a power plant and a chlor-alkali plant. The companies operating these facilities included Atlantic Refining Company, Georgia Power Company, Dixie Paints and Varnish Company (now the O'Brien Company), Allied Chemical Inc. (now Honeywell International, Inc.), and Hanlin Group subsidiary LCP Chemicals-Georgia, Inc.
Site investigations identified contamination in ground water, soil and sediments that could potentially harm people in the area. The contamination resulted from past manufacturing operations. Contaminants of concern identified include polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons and heavy metals, including mercury, lead, chromium, beryllium, arsenic and vanadium.
Site PRPs fenced areas with soil and sediment contamination to prevent unauthorized access. Although residences are located south of the site, ground water contamination does not threaten nearby residents because they live uphill from the site.
PCBs and mercury detected in the estuary near the site are currently inaccessible. Fishing advisories and signs are in place to discourage people from eating large amounts of certain types of fish from the estuary. EPA also plans to include land use restrictions in the final cleanup plans issued for the site.
The Agency for Toxic Substances and Disease Registry has prepared several reports and other materials on site-related public health issues.
Investigation and Cleanup Responsibility / Oversight
PRPs lead site investigation and cleanup activities, with oversight provided by EPA and Georgia EPD.
Site Cleanup Plan
Site investigations and cleanup activities have focused on three areas, which EPA refers to as operable units, or OUs. There areas include OU-1: Marsh Area; OU-2: Ground Water Contamination; and OU-3: Contaminated Upland Soil. In 1995, EPA initiated a remedial investigation/feasibility study (RI/FS). Site PRPs are currently working on an RI/FS for each OU; following the completion of the three RI/FSs, EPA will issue cleanup plans (Records of Decision, or RODs) for the site.
Between 1994 and 1999, PRPs undertook multiple removal actions, or short-term cleanup actions, to address site contamination considered the greatest potential threat to people and the environment. PRPs completed a removal action on the 70-acre upland portion of the site. The removal action included the excavation, or digging up, of contaminated soils and industrial process waste from 26 contaminated areas. The removal areas contained material contaminated with petroleum hydrocarbons (volatile organic compounds and semi-volatile organic compounds), mercury, alkaline sludges, PCBs and lead. The PRPs removed approximately 167,000 cubic yards of soil, sediment and waste.
Between 1998 and 1999, site PRPs extended the removal action cleanup to include approximately 13 acres of marshland and parts of the tidal channels. PRPs also dismantled petroleum process buildings and mercury cell buildings on site.
OU-1: Marsh Area
In August 2010, EPA approved the most recent draft of the baseline human health risk assessment (HHRA) for OU-1. EPA is currently finalizing a final draft of the OU-1 baseline ecological risk assessment (BERA). The feasibility study for OU-1 began in August 2011.
OU-2: Ground Water
In 2006, EPA authorized a removal action to address the caustic brine pool. The goals of the removal action are to reduce the level of alkalinity and density of the caustic brine pool to slow the spread of heavy metals below the shallowest aquifer. The removal action began in 2007 and included the installation of 12 extraction wells and 19 monitoring well clusters (two wells per cluster). In 2010, EPA determined that the caustic brine pool treatment system was not operating as intended. In late 2010, EPA requested a work plan for the construction of a conventional metals removal treatment system. EPA approved the work plan in April 2011. The site’s PRPs are currently conducting field studies to further evaluate caustic brine pool treatment options.
The RI/FS for OU-2 will begin in 2012.
OU-3: Contaminated Upland Soil
EPA and Georgia EPD are currently reviewing the most recent draft of the OU-3 HHRA submitted in July 2011. In August 2010, EPA approved the BERA for OU-3. Once EPA approves the HHRA, the feasibility study for OU-3 will begin.
EPA negotiated legal agreements with site PRPs to investigate and clean up the site. The PRPs funded site cleanup, monitoring and oversight activities. In 1998, EPA agreed to provide funding to assist with removal action efforts, and site PRPs agreed to reimburse EPA for all future costs.
EPA has worked with the community and its state partner to develop a long-term cleanup plan for the site, reflecting the Agency’s commitment to safe, healthy communities and environmental protection. Community engagement and public outreach are core components of EPA program activities.
EPA has conducted a range of community involvement activities to solicit community input and to make sure the public remains informed about site activities throughout the cleanup process. Outreach efforts have included public meetings and public notices regarding major cleanup activities.
The Glynn Environmental Coalition is an active community group engaged at the site. EPA’s site project manager provides quarterly site updates to the group and speaks at their monthly meetings.
EPA will finalize cleanup plans (RODs) for OU-1 and OU-3 in 2013.
EPA will continue to work with site PRPs to evaluate cleanup options for the caustic brine pool.
EPA keeps additional site documents and information in a site information repository at the location below. EPA also posts site documents, when available, on EPA’s CERCLIS Site Profile page. For documents not available on the website, please contact the Region 4 Freedom of Information Office.
