NPL Site Narrative for Armstrong World Industries

Macon, Georgia
Bibb County

iconSite Location:
   The Armstrong World Industries site consists of two areas in the southern portion of Macon, Georgia. The first area of concern is located on the Armstrong World Industries property, located at 4520 Broadway Street. The second is a remote landfill on the southern portion of the Armstrong property near Rocky Creek, and partially owned by the City of Macon Water Authority.

iconSite History:
   Since 1948, Armstrong World Industries has operated an acoustic ceiling tile manufacturing plant at the site. Three types of Armstrong ceiling tiles manufactured in 1969 and 1970 were coated with a commercial formulation of polychlorinated biphenyls (PCBs), and were recalled. Although these tiles were not manufactured in Macon, the plant is believed to have been used at some point to recycle the recalled tiles. Armstrong began disposing of general and industrial trash, old equipment and excess bark and scrap wood in the Armstrong remote landfill in the mid-1960s. The former Macon Naval Ordnance Plant (FMNOP), which operated during World War II on property adjacent to the Armstrong facility, also disposed of solid wastes, ordnance, used parts and construction debris in the remote landfill. This landfill area lies in the flood plain of Rocky Creek, and the landfills are eroded and are often partially submerged by Rocky Creek floodwaters. The FMNOP encompassed approximately 433 acres and manufactured flares, small primers, detonators and other triggering mechanisms during World War II.

iconSite Contamination/Contaminants:
   High levels of PCBs have been found in the wastewater treatment plant landfill located on the Armstrong property. The drainage pathways from this area and the adjacent Rocky Creek have become contaminated with high levels of PCBs, and a PCB fish consumption advisory has been placed on Rocky Creek. In addition, soil samples from the remote landfill area contained elevated concentrations of semi-volatile organic compounds, pesticides, PCBs and metals.

iconPotential Impacts on Surrounding Community/Environment:
   PCBs and metals contamination has been detected in Rocky Creek, and a PCB fish consumption advisory has been placed on Rocky Creek in the area of the site.

iconResponse Activities (to date):
   Several investigations have been conducted by EPA, the State of Georgia, and the U.S. Army Corps of Engineers at the site.

iconNeed for NPL Listing:
   The State of Georgia referred the site to EPA because of the extent of contamination of onsite soils and the PCB contamination in Rocky Creek. EPA received a letter from the state supporting listing of the site on the NPL.

[The description of the site (release) is based on information available at the time the site was evaluated with the HRS. The description may change as additional information is gathered on the sources and extent of contamination. See 56 FR 5600, February 11, 1991, or subsequent FR notices.]
