EPA ID: GAN000410033
Location: Macon, Bibb County, GA
Lat/Long: 32.77462N, -83.65170W
Congressional District: 08
NPL Status: Proposed: 10/21/2010; Final: Not Final

Affected Media: Fish Tissue, Groundwater, Sediment, Soil
Cleanup Status: Site Cleanup Planned
Site Reuse/Redevelopment: None
Site Manager: Brian Farrier (farrier.brian@epa.gov)

Current Status

The Site is approximately 130 acres and is divided into two parcels, the northern and southern.  The northern parcel is made up of the manufacturing area and includes the wastewater treatment plant (WWTP) area, the sludge storage landfill, known as the WWTP landfill (approximately 7.7 acres), and a landfill referred to as the Woodyard Landfill (approximately 3.8 acres).  The southern parcel contains a landfill referred to as the Armstrong Remote Landfill. 

Site Location

The Site is located at 4520 Broadway, in an industrial area in the southern portion of Macon, Bibb County, Georgia. The Site is bordered to the north by Guy Paine Road, to the east by Central of Georgia Railroad and Allied Industrial Park, to the south by the LaFarge Industries sand quarry and Rocky Creek, and to the west by Broadway (Highway 29).  Allied Industrial Park is the location of the Former Macon Naval Ordnance Plant (FMNOP), which also operated a 15 acre landfill adjacent to the Armstrong Remote Landfill.

Site Background

Since 1948, Armstrong has operated an acoustic ceiling tile manufacturing facility at the Site location.  Three types of Armstrong ceiling tiles manufactured in 1969 and 1970 were coated with a formulation containing polychlorinated biphenyls (PCBs).  Armstrong representatives have stated that these ceiling tiles were not manufactured at the Site, nor were they ever recycled there; instead, possible sources of PCB contamination at the Site are recycled raw materials and recycled newsprint with older dye formulations.  Armstrong began disposing of general and industrial trash, old equipment, and excess bark/scrap wood in the Armstrong Remote Landfill in the mid-1960s.  From around 1970 to the late 1980s, wastes generated at the Site were stockpiled in the WWTP Landfill, including excess fiber filtered from the WWTP influent.  The Woodyard Landfill was constructed in the late 1970s or early 1980s and was also used for disposal of this filtered fiber material.  During the late 1980s and early 1990s, disposal of filtered sludge waste ceased at the WWTP landfill, after which all this material was disposed at the Woodyard Landfill.  Sludge generated at the WWTP is currently sent off-site to a local industrial landfill.
