Permit Application for Renewal Complete: On July 16, 2008, Lone Star 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 Cape Girardeau Public Library, 711 N. Clark St., Cape Girardeau (during normal business hours) or agency 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 by mail to Nathan Kraus, PE, Missouri Department of Natural Resources, Hazardous Waste Program, P.O. Box 176, Jefferson City, MO 65102-0176.
The Lone Star Industries Inc. site is located on about 2,023 acres at 2524 S. Sprigg St. in Cape Girardeau. The Harrison Interests began operating a cement plant at the site in 1910. By 1923, the facility was purchased by The Marquette Co., who immediately began a major improvement project. In 1957, The Marquette Co. installed a new “wet process” plant at the site. In 1977, designs began for construction of a “dry process” preheater/precalciner plant to replace the existing wet process plant. The new plant, which is more energy efficient, was put into operation in April 1981. In April 1982, Lone Star Industries Inc. acquired The Marquette Co. and the Cape Girardeau plant. The Marquette Co. and Lone Star merged into a single corporation, Lone Star Industries Inc., in 1987. Dyckerhoff Inc. acquired Lone Star in 1999 and Buzzi Unicem, a majority stockholder of Dyckerhoff, took over operation of the company in January 2004.
Lone Star, doing business as (dba) Buzzi Unicem USA, currently operates a dry process rotary cement kiln with a four-stage preheater and a precalciner. The kiln produces clinker, the main ingredient in Portland cement. The cement production process involves crushing and grinding raw material; such as limestone, fireclay, and shale; into a fine dust. Lone Star feeds the raw material, in dry powder form, into a preheater/precalciner tower, which is made up of a series of cyclones. As the powder slowly falls through the cyclones, it is mixed with increasingly hot gasses from the kiln. The powder enters the kiln when it has been heated to a point to start the chemical reaction that makes clinker. The clinker is then ground with gypsum to make cement. A byproduct of the cement production process is a fine chalky powder waste known as cement kiln dust. Lone Star regularly tests the dust to make sure that it is exempt from being classified as a hazardous waste. The dust is placed in on-site landfills.
Lone Star uses mainly coal to heat their kiln system. To supplement its fuel needs, Lone Star also uses non-hazardous waste fuels, such as shredded plastics, sawdust and used oil, and solid and liquid hazardous wastes fuels. Lone Star is permitted to use hazardous waste fuel in both the rotary kiln and calciner portions of the kiln system. Lone Star has been using specific types of hazardous waste as a fuel since April 1992. Most of the hazardous waste comes from off-site hazardous waste generators or third party hazardous waste blenders or brokers. Lone Star receives the hazardous waste in bulk tanker trucks and 55-gallon drums. The liquid hazardous wastes are “blended” with other hazardous waste to achieve the desired characteristics, such as BTU value and metals and chlorine content. The resulting wastes are stored in tanks until they are used as liquid fuel.
Lone Star currently operates two hazardous waste container storage areas: the drum storage building with a capacity of 54,000 gallons and five truck storage bays with a capacity of 6,000 gallons in each bay; and a tank farm consisting of six 40,000-gallon hazardous waste storage/blend tanks, two 150,000-gallon hazardous waste storage/blend/burn tanks and one 1,100-gallon disperser tank. Lone Star stores and treats characteristic hazardous waste and various F-, K-, P-, and U-listed hazardous wastes, as specified in their Part A permit application.
Corrective Action Status
According to applicable state and federal hazardous waste laws and regulations, all hazardous waste treatment, storage and disposal facilities are required to investigate and clean up hazardous waste releases at their facility resulting from present and past hazardous waste handling practices. In 1993, PRC Environmental Management Inc. performed a Resource Conservation and Recovery Act, or RCRA, Facility Assessment for the site, on behalf of EPA. The assessment was conducted to identify and gather information on potential or actual releases of hazardous waste and hazardous constituents to the environment. The 1993 RCRA Facility Assessment Report identified 56 solid waste management units and seven areas of concern; of which 15 solid waste management units and 4 areas of concern required more investigation.
In response to the assessment, Lone Star investigated the solid waste management units and areas of concern with department oversight. The results of these activities are documented in a Solid Waste Management Unit, Corrective Action Evaluation Report, dated April 1995, and follow-up Summary Report Solid Waste Management Units and Areas of Concern, dated Aug. 27, 1996. Based on review of these documents, the department determined that all issues associated with the solid waste management units and areas of concern had been adequately addressed and no further corrective action was necessary at that time. Lone Star continues to operate, monitor and maintain the cement kiln dust landfill.
Lone Star Industries is operating 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 Feb. 16, 1999. EPA issued the Hazardous and Solid Waste Amendments Part II Permit, effective March 18, 1999. These permits allow Lone Star to receive and store liquid and solid hazardous waste in tanks and containers, mix hazardous waste to meet fuel specifications and burn hazardous waste-derived fuel in their rotary cement kiln. The regulated units consist of two hazardous waste container storage areas, a tank farm, container processing equipment, truck unloading facilities and fuel blending equipment. These permits also require corrective action in the event there is a hazardous waste release to the environment.
On June 29, 2006, the department approved Lone Star’s Class 2 Permit Modification request, allowing Lone Star to add addition waste codes and expand the existing drum storage area. On Nov. 14, 2007, the department and EPA issued Part I and Part II Class 3 Permit Modifications to Lone Star, allowing Lone Star to convert two burn tanks into storage/blending tanks and build and operate two new burn tanks. On June 4, 2012, the department and EPA issued Part I and Part II Class 3 Permit Modifications to Lone Star, allowing Lone Star to use hazardous waste fuel in the calciner, accept additional hazardous waste codes and increase their treatment capacity per day for drum processing. On March 28, 2013, the department approved Lone Star's Class 2 Permit Modification request, allowing Lone Star to build equipment that will allow them to fluidize sludge-like hazardous waste until amenable to pumping into storage and eventually used as fuel in the kiln system.
Lone Star submitted a permit application on July 16, 2008, for renewal of their existing hazardous waste permits. The facility’s existing Part I Permit expired Feb. 16, 2009, and Part II Permit expired March 18, 2009. State and federal regulations, 40 CFR 270.51, allow the existing hazardous waste permits to continue in effect until the department and EPA issue or deny new hazardous waste permits. The department determined the permit application was complete on July 17, 2009. The department is conducting a technical review of the permit application.
