What’s New

Facility Closing: On Feb. 15, 2012, Holcim (US) Inc./Geocycle, LLC notified the Missouri Department of Natural Resources and U.S. Environmental Protection Agency Region 7 that they were withdrawing their application to renew their hazardous waste permits and intended to close the facility. On June 28, 2012, Holcim/Geocycle submitted to the department and EPA a notice to begin closure activities. Holcim/Geocycle has begun closing the facility according to their department-approved closure plan. The public can review and copy paper copies of all permits, plans, reports and supporting documents at the agency locations above.

Facility Description

Holcim (US) Inc./Geocycle, LLC was a hazardous waste treatment and storage facility, located at 14744 Highway 79 North, two miles north of Clarksville. Holcim operated a single, wet process cement kiln, which produced approximately 4,000 tons of clinker per day. Clinker is the main ingredient in Portland cement. The main fuel used to heat the kiln was coal/coke. About 470 pounds of coal was needed to produce one ton of cement. To supplement their fuel needs, Holcim used a variety of liquid and solid hazardous waste-derived fuels as well as tires, sawdust, oil filter fluff and other non-hazardous materials. One ton of hazardous waste fuel supplemented about one ton of coal.

Geocycle operated the on-site liquid and solid hazardous waste fuel programs. Geocycle would receive the hazardous waste by both truck and railcar. The liquid hazardous wastes were blended to achieve the desired fuel characteristics and stored until they were fed into the kiln as liquid fuel.

The facility is currently closing. Holcim closed the kiln during the first part of 2009. The department accepted the kiln closure certification in October 2009.  

Hazardous Waste Permit Status

Holcim/Geocycle operated under two hazardous waste permits, one issued by the department and one issued by EPA. The department issued the Missouri Hazardous Waste Management Facility Part I Permit, effective May 2, 2000. EPA issued the Hazardous and Solid Waste Amendments Part II Permit, effective June 16, 2000. These permits allowed Holcim/Geocycle to store hazardous waste in containers and tanks and treat hazardous waste in tanks. The regulated units consisted of eight blend/storage tanks and a railcar storage area. These permits also required corrective action in the event there is a release of hazardous waste or hazardous constituents to the environment.

Holcim/Geocycle submitted a permit application on Oct. 29, 2009, for renewal of their existing hazardous waste permits. Holcim/Gocycle has since decided to permanently stop operations at the facility and begin the closure process. Holcim/Geocycle's existing Part I Permit expired May 2, 2010 and Part II Permit expired June 16, 2010. State regulations allow the existing permits to continue in effect until the facility is closed according to their approved closure plan and a determination is made regarding any corrective action, or cleanup. All hazardous waste treatment, storage and disposal facilities are also required to investigate and clean up hazardous waste releases at their facility resulting from present and past hazardous waste handling practices.
