What’s New

Permit Application for Renewal Complete: On Nov. 19, 2011, Lake City Army Ammunition Plant submitted a permit application to the department and U.S. Environmental Protection Agency Region 7, to renew their existing Missouri Hazardous Waste Management Facility Part I Permit and Hazardous and Solid Waste Amendments Part II Permit. The department is inviting the public to review and offer written comments on the permit renewal application while the department conducts a technical review of the permit application.

The public can review and copy the permit application and supporting documents at the locations above. Comments on the permit application are more effective if they point out legal or technical issues. You may submit written comments online or send comments by mail to Nathan Graessle, Missouri Department of Natural Resources, Hazardous Waste Program, P.O. Box 176, Jefferson City, MO 65102-0176.

Facility Description

The Lake City Army Ammunition Plant site is located on about 3,935 acres at the intersection of Highways 7 and 78 in Independence. This Class II government-owned contractor-operated military industrial installation was established in 1941 to manufacture and test small caliber ammunition for the U.S. Army. The facility has remained in continuous operation except for a five-year period between the end of World War II and the beginning of the Korean conflict. The plant is the largest small-arms manufacturing plant in the world.

Lake City AAP is owned by the Department of the Army and operated by Alliant Lake City Small Caliber Ammunition Co., LLC. The plant routinely manufactures various types of 5.56 mm, 7.62 mm, cal .50 and 20 mm ammunition as required by the Department of Defense. Additional small caliber ammunition has been and may be manufactured upon request. These include .38 special, caliber .45 and 30 mm.

Area 8 of the Lake City AAP contains a landfill that operated from the mid-1960s until 1988. The landfill was used to dispose of sludge and dewatered oil residue from an industrial wastewater treatment plant. The landfill contains four cells, two of which (cell 1 and 2) contain K046 hazardous waste. K046 waste is wastewater treatment sludge from the manufacturing, formulation and loading of lead-based initiating compounds. During the operating life of cells 1 and 2, approximately 35,000 cubic yards of K046 waste was disposed. Cell 3 was never used. Cell 4 was used to dispose of non-hazardous sludges after 1986, when lead-based initiating compound wastewater was no longer being processed.

Lake City AAP currently stores “characteristic” hazardous waste as well as various F-, K- and U-listed hazardous wastes and operates an incinerator for off-specification and obsolete ammunition. Lake City AAP received a hazardous waste permit to incinerate explosives on Nov. 8, 1989. The incinerator consists of a rotary kiln with an air pollution control system and is designed to demilitarize obsolete or unserviceable ammunition items, scrap propellant powders and explosive wastes.

Post-Closure and Corrective Action Status

The department accepted Lake City AAP’s closure report and certification for the Area 8 landfill in September 2010; however, because hazardous waste remained in place after closure, the area is also required to go through a period of post-closure care. As part of the post-closure care, Lake City AAP is required to conduct groundwater monitoring and routine maintenance until all conditions contained in their department-approved post-closure plan have been met.

Historic waste handling and disposal practices of hazardous substances, including oil, grease, solvents, explosives and metals, has led to widespread contamination of the site. Lake City AAP was placed on the Superfund National Priority List on Aug. 21, 1987. Environmental cleanup activities for the units identified in the approved permit application are being performed under the Comprehensive Environmental Response, Compensation, and Liability Act, or CERCLA, through the Lake City Army Ammunition Plant 120 Interagency Agreement. 

Hazardous Waste Permit Status

The Lake City Army Ammunition Plant is operating and conducting post-closure and corrective action activities under two hazardous waste permits, one issued by the department and one issued by EPA, both effective May 17, 2002. The department issued the Missouri Hazardous Waste Management Facility Part I Permit. EPA issued the Hazardous and Solid Waste Amendments Part II Permit. These permits allow Lake City to store “characteristic” hazardous waste as well as various F-, K-, and U-listed hazardous wastes, as specified in their Part A permit application. The hazardous wastes include obsolete and off-specification ammunition produced on- and off-site by Alliant Lake City Small Caliber Ammunition Company LLC, the Department of Defense and Department of Defense contractors, as well as other production and maintenance related wastes generated on site. These permits also require corrective action in the event there is a release of hazardous waste or hazardous constituents to the environment.

Lake City submitted a permit application on Nov. 19, 2011, for renewal of their existing hazardous waste permits, which expired May 17, 2012. The department determined the permit application was not complete. As a result Lake City AAP submitted amendments to the permit application March 8, 2012. The department determined the permit application was complete on March 22, 2012. The department is conducting a technical review of the permit application.
