### ARMSTRONG WORLD INDUSTRIES Macon, Georgia
Bibb County

 **Site Location :**  The Armstrong World Industries s ite consists of two areas in the southern portion of Macon, Georgia. The first area of

co ncern 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.

 **Site History:** Since 1948, Armstrong World Industries has operated an acoustic ceiling tile manufacturing plant at the site. Three types of Armstrong ceiling tiles (Travertone Sanserra, Santaglio, and Embossed Design) manufactured in 1969 and 1970 were

c oated with a formulation containing a commercial formulation of poly chlorinated biphenyls ( PCBs ) , and were recalled

. Although these tiles were not manufactured in Macon, the plant is believed to have been used to recycle the recalled tiles at some point. 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 fo rmer Macon Naval Ordnance Plant (FMNOP), which operated during World War II on property adja cent 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.

 **Site Contamination/Contaminants:** High levels of PCBs (Aroclor

- 1248, Aroclo r- 1254, and Aroclor

- 1260) have been found in the w astewater 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 con sumption advisory has been placed on Rocky Creek. In addition, soil samples from the remote landfill area contained elevated concentrations of semi

- vo l atile organic c ompounds (SVOCs) , pesticides, PCBs, and metals.

 **Potential Impacts on Surrounding Comm unity/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 s ite.

 **Response Activities (to date):** Several investigations have been conducted by EPA, the State and the U.S. Army Corp s of Engineers ( USACE ) at the Site.

 **Need for NPL Listing:**

The S tate of Georgia referred th e site to EPA because of the extent of contamination of on

- site soils and the PCB contamination in Rocky Creek

. EPA receive d a letter from the s tate 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 evalu ated with the HRS. The description may change as additional information is gathered on the sources and extent of contamination.]
