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 and Background

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.

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.

Threats and Contaminants

Potential future risks to public health and the environment exist at the site due to contamination documented in on-site soils/sediments and Rocky Creek.  The primary contaminants found in the site soils and sediments are PCBs.

Site Cleanup Plan

On September 16, 2010, an Administrative Order on Consent (AOC) was signed with Armstrong World Industries to conduct an Engineering Evaluation/ Cost Analysis (EE/CA) for Operable Unit One, which was defined as the WWTP Landfill.  The EE/CA was completed in 2013 and identified options for addressing the WWTP Landfill as part of a Non-Time-Critical Removal Action (NTCRA).

On July 7, 2014, an Administrative Order on Consent (AOC) was signed with Armstrong World Industries to conduct a NTCRA on the WWTP Landfill.  The option selected from the EE/CA was “Surface Cap/Liner With a Barrier Wall and Swale Replacement”.

Cleanup Progress

The Woodyard Landfill was officially closed in 2004, following a closure plan approved by the Georgia Environmental Protection Division (GaEPD).

Enforcement Activities

Two Administrative Orders on Consent (AOC), in September 2010 and July 2014, have been signed with Armstrong World Industries to address the WWTP Landfill.

Community Involvement

EPA has conducted community involvement activities at the Armstrong World Industries Site to solicit community input and to ensure that stakeholders and the public remain informed about Site activities throughout the NPL cleanup process.  In April 2011, the Macon City Council and Bibb County Commission were briefed, and a public availability session was held, with EPA and State of Georgia representatives available to answer questions about the site.

Future Work

The Non-Time-Critical Removal Action work should begin on the WWTP Landfill in 2015. 

An Administrative Order on Consent (AOC) will be pursued with Armstrong World Industries to conduct a Remedial Investigation/Feasibility Study for Operable Unit Two, which will include the Armstrong Remote Landfill and Rocky Creek.
