The Macon Naval Ordnance Plant site includes an active industrial park. Since 1941, manufacturing operations have taken place at the site. The EPA proposed the site for listing on the National Priorities List (NPL) in 2012 because of contaminated ground water, surface water, soil and sediment resulting from facility operations. The EPA, with support from the Georgia Environmental Protection Division (Georgia EPD), will finalize the site on the NPL by May 2013 and is in the process of identifying potentially responsible parties (PRPs) to fund site investigations and cleanup.
Site Location and Background
The 433-acre site is an active industrial park south of Macon, Georgia. The industrial park includes several facilities and storage areas from former operations, along with several new facilities and structures. Guy Paine Road borders the site to the north, while the Armstrong World Industries Superfund site borders the site to the west. Macon Water Authority Rocky Creek Water Reclamation Facility, Rocky Creek, and a former landfill used by both Armstrong and the Navy border the site to the south. Mead Road and Norfolk Southern railroad tracks border the site to the east.
From 1941 until 1965, the U.S. Navy conducted ordnance manufacturing and metal plating at the site. In 1965, Maxon Electronics Company purchased the site property and continued ordnance manufacturing until it sold the property to Allied Chemical Corporation in 1973. It made seat belts at the site from 1973 until 1981. Improper handling, storage and disposal of explosive compounds, chemicals used during ordnance manufacturing and metal plating operations, and wastes resulted in contamination of ground water, surface water, soil and sediment. In 2012, the EPA proposed the site for listing on the NPL.
Macon-Bibb County Industrial Authority has operated Allied Industrial Park on the site property since 1980. It leases or sells on-site buildings for commercial and industrial uses.
Threats and Contaminants
Site investigations found contamination in ground water, surface water, soil and sediment that could potentially harm people in the area. Contamination resulted from improper handling, storage and disposal practices. Contaminants of concern include trichloroethylene (TCE), mercury, cadmium, pesticides and polychlorinated biphenyls (PCBs).
The EPA found PCBs in site soils at levels that would not pose a public health threat given the current land use at the site.
Contamination has affected Rocky Creek and its associated wetlands. Rocky Creek is not a source of drinking water. The public has been advised not to eat fish from Rocky Creek.
In 2009, the EPA found TCE contamination in ground water beneath the site at levels up to 20,000 micrograms per liter (µg/L). The federal drinking water standard for TCE is 5 ug/L. Further work is needed to define this area of TCE-impacted ground water.
Investigation and Cleanup Responsibility / Oversight
The EPA is overseeing NPL listing activities for the site with support from the Georgia EPD.
In 2009, the EPA conducted an expanded site inspection (ESI), which included sampling of site soils, ground water, surface water and sediment. The EPA is using the information from the 2009 ESI as part of its efforts to finalize the site’s listing on the NPL.
Site Cleanup Plan
No physical response actions have been taken to date.
The EPA is planning a preliminary vapor intrusion study in 2013 due to the TCE ground water contamination.
The EPA has conducted preliminary sampling activities as part of the NPL listing process.
The EPA is working to identify PRPs to fund site investigation and cleanup activities.
On March 8, 2013, the EPA hosted an on-site public availability session to update the community regarding the site’s proposed listing on the NPL.
The EPA is working 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.
The EPA will conduct a range of community involvement activities to ask for community input and to make sure the public remains informed about site activities throughout the cleanup process. Outreach efforts will include public notices and meetings.
The EPA will finalize the site on the NPL in 2013.
The EPA keeps additional site documents and information in a site information repository at the location below. The EPA also posts site documents, when available, on the EPA’s CERCLIS Site Profile page. For documents not available on the website, please contact the Region 4 Freedom of Information Office.
The EPA has not yet established a repository for the site.
